 ### Functional
 
 - [Reused depth storage](../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp): a storage view with another extent or a format that cannot hold the cached depth plane uses guest memory. Depth rendering is not written back to those guest bytes; this admission rule does not prove allocation reuse or preserve a depth writer through an incompatible view. Matching depth/stencil storage access still throws.
+- [pthread_mutexattr_getpshared and pthread_mutexattr_setpshared](../../core/libs/prx/libkernel/Pthread/Posix/Mutex.cpp) (libkernel) support process-private mutexes. Setting `PTHREAD_PROCESS_SHARED` returns `ENOTSUP` because mutexes use process-local host objects; no attribute is changed on failure. Values 0 and 1 and guest error 45 follow FreeBSD's [pthread.h](https://github.com/freebsd/freebsd-src/blob/main/include/pthread.h) and [errno.h](https://github.com/freebsd/freebsd-src/blob/main/sys/sys/errno.h); the unsupported-sharing error follows [pthread_mutexattr_setpshared](https://man7.org/linux/man-pages/man3/pthread_mutexattr_getpshared.3.html). PS5 shared-mutex behavior and invalid-attribute error precedence are unverified.
 
 - [sceAudioInHqOpen, sceAudioInAsyncOpen](../../core/libs/prx/libSceAudioIn/Export.cpp) (libSceAudioIn) open the same port as `sceAudioInOpen`, so `sceAudioInInput`, `sceAudioInGetSilentState` and `sceAudioInClose` accept their handles. The signatures agree across [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/fc5d2cc219c43c8c8f354153e7b3d0c04a5d506e/src/core/libraries/audio/audioin.cpp), [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/60977b29103452b9681ae10c7a9011d44965bf16/src/SharpProspero/Interop/Audio/AudioIn.cs) and [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/c86c8b4d9333a766cc8c4495f89f893bf35e6199/src/libs/audio.cpp). HqOpen is limited to 128 samples at 48 kHz; AsyncOpen rejects sizes above 384 and throws for currently unverified inputs. Host capture pacing and console behavior remain unverified.

 ### Functional
 
+- [__isfinitel](../../../core/libs/prx/libc/src/Math.cpp) - classifies the x87 80-bit exponent without narrowing to double or performing floating-point comparisons, following [FreeBSD msun](https://github.com/freebsd/freebsd-src/blob/main/lib/msun/src/s_isfinite.c). The signature and classification follow FreeBSD; console behaviour is unmeasured. Requires little-endian x87 long double stored in 16 bytes, as the existing guest long-double ABI does.
+
 - [getc_unlocked, putc_unlocked](../../../core/libs/prx/libc/src/StandardStreams.cpp) (libc) - byte I/O uses the host unlocked operations; guest EOF/error flags and macro counters follow `FileStream`. Linux status queries use `feof_unlocked`/`ferror_unlocked` because [glibc `feof`](https://github.com/bminor/glibc/blob/d2097651cc57834dbfcaa102ddfacae0d86cfb66/libio/feof.c) and [`ferror`](https://github.com/bminor/glibc/blob/d2097651cc57834dbfcaa102ddfacae0d86cfb66/libio/ferror.c) can acquire the stream lock. Windows uses [the CRT no-lock byte operations](https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/fgetc-nolock-fgetwc-nolock) and `feof`/`ferror`, verified under a held stream lock on UCRT. Console behavior and other host CRTs remain unverified.
 - [ftrylockfile](../../../core/libs/prx/libc/src/RuntimeSupport.cpp) (libc) - tries the host CRT stream lock that `flockfile`, `funlockfile` and each locking host stdio call on the stream take, so it returns -1 while another thread holds the stream through `flockfile` or is inside such a call, and 0 when it acquires the lock or already owns it (recursively, released by as many `funlockfile` calls), as FreeBSD 11 [`_ftrylockfile`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdio/_flock_stub.c#L89-L104) does. A libc export holds the lock only for each host call it makes, not across several host calls or while it updates the guest `FILE` prefix. Linux uses glibc `ftrylockfile`. UCRT has no try variant of `_lock_file`, so Windows calls `TryEnterCriticalSection` on the `CRITICAL_SECTION` that `_lock_file` enters, found through the private UCRT stream layout (`__crt_stdio_stream_data` in `ucrt/inc/corecrt_internal_stdio.h`, unchanged from Windows SDK 10.0.19041 to 10.0.26100); another CRT or a change of that layout breaks it. A null or closed stream throws where FreeBSD dereferences it
 - [Wide-character conversions](../../../core/libs/prx/libc/src/Multibyte.cpp) (libc) - The wide `wcsto*` functions parse the ASCII prefix of the guest string, as the C locale accepts only ASCII white space and digits. [`wcsrtombs`](../../../core/libs/prx/libc/src/Multibyte.cpp) uses the guest's single-byte C locale through `wcrtomb`; other encodings and shift states are not supported

Subject: [PATCH 0007/1000] fix(libSceAudiodec): decode HE-AAC as the console
 does

ui_enable_heaac was ignored and FFmpeg applied Parametric Stereo, so an
HE-AAC v2 stream decoded to 48 kHz stereo whatever the flag: 2048
samples in 2 channels per frame, and ERROR_INVALID_PCM_SIZE for a PCM
buffer sized for the console's output. The console returns the 24 kHz
mono core with HE-AAC disabled, and SBR output at 48 kHz in one channel
with it enabled.

AAC access units now reach FFmpeg without their ADTS header, with an
AudioSpecificConfig built from the header or from the raw parameters.
With HE-AAC disabled it signals SBR as absent. With HE-AAC enabled SBR
stays implicit, and a mono stream that FFmpeg decodes to two channels
is reopened with SBR present and Parametric Stereo absent. The new test
decodes fdk-aac HE-AAC v2 and HE-AAC stereo streams, ADTS and raw, with
HE-AAC on and off; it aborts on main.

 ### Unknown function info
 
 - [sceAudiodecDecode](../../../core/libs/prx/libSceAudiodec/src/Codecs.cpp) (libSceAudiodec) - a raw M4AAC stream carries no channel configuration, so the decoder tries the mono/stereo configuration and then configurations 3 to 7 within `ui_max_channels` until one decodes the first access unit, and keeps that one. No reference documents how the library picks the layout (shadPS4 maps the channel count straight to the configuration; SharpProspero only describes the maximum). With the stereo configuration a mono raw stream decodes as 2 channels, so 2 is reported, not 1
+- [sceAudiodecDecode](../../../core/libs/prx/libSceAudiodec/src/Codecs.cpp) (libSceAudiodec) - the HE-AAC handling follows one console measurement of an HE-AAC v2 ADTS stream: SBR output at 48 kHz in one channel with `ui_enable_heaac` 1, the 24 kHz mono core with 0. Not measured: whether the console, like FFmpeg, decodes a stream without SBR data in its first access unit as AAC-LC with `ui_enable_heaac` 1, and what it reports in `ui_sampling_freq` and `ui_heaac` with `ui_enable_heaac` 0 (here the rate of the returned PCM and 0)
 
 ### Functional
 
+- [sceAudiodecDecode](../../../core/libs/prx/libSceAudiodec/src/Codecs.cpp) (libSceAudiodec) - an ADTS stream with channel configuration 0 (layout in a program config element) is still parsed by FFmpeg, so `ui_enable_heaac` 0 does not remove its SBR and a mono one with Parametric Stereo comes out as stereo.
 - [libSceAudiodec](../../../core/libs/prx/libSceAudiodec/Export.cpp) throws for the 24-bit PCM word size (`iBwPcm` 0): its sample layout is unknown. ATRAC9 decoding is covered only by configuration and error tests, as no ATRAC9 encoder is available for a fixture.

Subject: [PATCH 0008/1000] perf(shader): compute scalar f16 add, sub and mul
 with native f16 math

v_add_f16, v_sub_f16, v_subrev_f16 and v_mul_f16 converted their
sources to f32, computed in f32 and converted the result back. When the
device has native f16 that rounds to nearest even and keeps f16
denormals, and FLOAT_MODE does the same for f16 (or the shader has no
FLOAT_MODE), they are now one f16 add or mul on the source bits (sub
adds the negated subtrahend), followed by the FP16_OVFL and clamp rules
on the result bits. Other f16 modes, including the f16 denormal
flushes, keep the f32 path.

Results other than NaN payloads don't change, for the same reason as
for the packed instructions: rounding an f16 sum or product to f32 and
then to f16 gives the correctly rounded f16 result, which Vulkan
requires of f16 OpFAdd and OpFMul. A NaN result keeps the payload the
driver gives, as before (TechnicalDebt lists the NaN payloads of scalar
f16 arithmetic as the driver's); it is now the payload of the driver's
f16 arithmetic rather than of its f32 arithmetic.

v_fma_f16, v_fmac_f16, v_fmamk_f16 and v_fmaak_f16 keep their exact f32
path, since a native f16 Fma is not required to be fused.

New test agc_driver_float16_native compiles one shader with these
instructions and the fma forms (abs, neg, op_sel, clamp, inline
constant and literal variants) with and without Float16, checks that
only add and mul use f16 math, and compares the results bit for bit in
ten float modes, accepting another NaN payload only where both results
are NaN, and checks that a mode that flushes f16 denormals keeps the
f32 path.

Subject: [PATCH 0009/1000] test(agc): bound native f16 SPIR-V scanner reads

FindF16x2Math read spirv[offset + 1] for every instruction once the f16 vector type was known, so a final one-word OpFunctionEnd read past the module. Check the opcode and its minimum word count before reading operands.

Subject: [PATCH 0010/1000] test(agc): word the native f16 skip as a device
 limitation

check_skips.py accepts a skip only when its message reads "skipped, the
device has no ...". Float16Native printed the reason before "skipped",
so the Linux job rejected its expected skip on llvmpipe. Use the wording
PackedFloat16Native already has.

 ### Functional
 
-- [pthread_mutexattr_getpshared and pthread_mutexattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Mutex.cpp) (libkernel) support process-private mutexes. Setting `PTHREAD_PROCESS_SHARED` returns `ENOTSUP` because mutexes use process-local host objects; no attribute is changed on failure. Values 0 and 1 and guest error 45 follow FreeBSD's [pthread.h](https://github.com/freebsd/freebsd-src/blob/main/include/pthread.h) and [errno.h](https://github.com/freebsd/freebsd-src/blob/main/sys/sys/errno.h); the unsupported-sharing error follows [pthread_mutexattr_setpshared](https://man7.org/linux/man-pages/man3/pthread_mutexattr_getpshared.3.html). PS5 shared-mutex behavior and invalid-attribute error precedence are unverified.
-
 - [JIT shared memory](../../../core/libs/prx/libkernel/DirectMemory/Jit.cpp) (libkernel) - `sceKernelJitCreateSharedMemory`, `sceKernelJitCreateAliasOfSharedMemory` and `sceKernelJitMapSharedMemory` take the signatures of [Orbital](https://github.com/AlexAltea/orbital)'s `tools/ida/db_types.json` (name, length, maximum protection, descriptor out; descriptor, maximum protection, descriptor out; descriptor, protection, address in and out), which ps4sdk, ps5-jar-loader and the call sites in RetroArch PPSA99169, XPSemu PPSA97358 and VLC PPSA85300 match; SharpProspero declares the alias as returning the descriptor. The object is a host anonymous file shared by its descriptors (a `memfd` on Linux, a delete-on-close temporary file mapped as an executable section on Windows), the alias is a duplicate descriptor, and every map maps the whole object, so writes through one view show through the others; a non-null address is a hint, as in `mmap` without `MAP_FIXED`. Not measured on the console: a length that is zero or not a multiple of 16 KiB and protection bits other than CPU read, write and execute are `EINVAL`; an alias or a map asking for more than the descriptor's maximum protection (write and execute counting as read) is `EACCES`, as FreeBSD 11's `vm_map_protect` treats a protection past `max_protection`; a descriptor that is not a JIT object is `EBADF`. The name is ignored, the objects do not count against the flexible memory budget, `mprotect` of a view is not limited to the maximum protection, and `mmap` of the descriptors is unsupported, as for `shm_open`. On Linux the `memfd` is created without `MFD_EXEC`, which Linux 6.3 added and older kernels reject with `EINVAL`, and relies on the protection of the mapping: the flag only sets the file's execute permission bits, and the direct memory `memfd` is mapped executable the same way; a host with `vm.memfd_noexec` set to 2 refuses the creation and the call throws
 - [kqueue and kevent](../../../core/libs/prx/libkernel/Equeue/src/Kqueue.cpp) (libkernel) follow FreeBSD 11's [`kern_event.c`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/kern_event.c) (`kqueue_kevent`, `kqueue_register`, `kqueue_scan`, the timer and user filters) over the event queue; nothing is measured on a console. The descriptor is a host null device registered as the kqueue: `close` and `sceKernelClose` close the queue and `dup`/`dup2` of it throw, but `read`, `write` and `fstat` act on the null device instead of failing with `EOPNOTSUPP` or reporting `S_IFIFO`. Read and write events are supported on guest sockets only, plus the timer, user and [vnode](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) filters; other filters, `EV_DISABLE`, `EV_DISPATCH`, `EV_FORCEONESHOT`, `NOTE_LOWAT`, `EV_CLEAR` on a socket, `EVFILT_READ` on another kqueue, a `NOTE_NSECONDS` period above one second with a fraction (11.0 converts the fraction with the microsecond macro), any change to an existing timer (11.0 keeps the armed expiry and applies the new period after it, 11.4's `filt_timertouch` restarts it) and a negative `nevents` throw. A new user event keeps its `fflags` unmasked and is not triggered by `NOTE_TRIGGER`, because `filt_userattach` reads the already cleared `kn_fflags`. The timer limit `kq_calloutmax` (`ENOMEM`) is not enforced, and closing a kqueue wakes a thread waiting on it in `kevent` with `EBADF`, where `kqueue_drain` makes the close wait for that thread. A level-triggered event is reported once per call and moved behind the other events, as in `kqueue_scan`; the `sceKernel*Equeue` calls keep their own collection loop
 - [EVFILT_VNODE, sceKernelAddFileEvent and sceKernelDeleteFileEvent](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) (libkernel) watch the host file or directory behind the descriptor and turn host changes into FreeBSD 11 vnode hints, which [`filt_vfsvnode`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L5032) adds whole when they share a bit with the requested `fflags`: a write that grows a file is `NOTE_WRITE | NOTE_EXTEND`, another write `NOTE_WRITE`, a shrinking truncate or an attribute change `NOTE_ATTRIB`, a higher link count `NOTE_LINK`, a lower one or a pending delete `NOTE_DELETE`, a new path `NOTE_RENAME`; in a directory, an entry created, removed or renamed is `NOTE_WRITE`, with `NOTE_LINK` for a subdirectory, and on Linux an entry moved from or to another directory adds `NOTE_EXTEND`; inotify queues the two halves of a rename one after the other, so a watcher woken by the first can read it alone, and a half read without the other is classified only after a `getdents64` on the watched directory, which takes the directory lock that `rename` holds until both halves are queued ([`do_renameat2`](https://github.com/torvalds/linux/blob/v6.8/fs/namei.c#L4975) around `vfs_rename` and its `fsnotify_move`, [`iterate_dir`](https://github.com/torvalds/linux/blob/v6.8/fs/readdir.c#L103)), an ordering taken from the kernel source, not from inotify(7), which promises none; a directory registered with `NOTE_EXTEND` on Windows is accepted, as `vfs_kqfilter` does not check it, but never receives it, because the directory handle cannot tell a move between directories from a removal plus an addition. FreeBSD's hints depend on the filesystem and the console's filesystems are not known: a growing `ftruncate` reports `NOTE_WRITE | NOTE_EXTEND` where `vop_setattr_post` reports `NOTE_ATTRIB`, and on Windows `utimes` on a file reports `NOTE_WRITE`. Windows uses `FindFirstChangeNotification` on the parent directory (and on a watched directory itself) and compares `GetFileInformationByHandleEx` snapshots at least every 50 ms, because a write through an open handle is reported only when the handle is flushed or closed, so file hints can arrive 50 ms late; Linux uses inotify on the file and is not run. `NOTE_REVOKE`, `NOTE_OPEN`, `NOTE_CLOSE`, `NOTE_CLOSE_WRITE`, `NOTE_READ`, unknown bits and descriptors other than files, directories, pipes and sockets throw. `sceKernelAddFileEvent(eq, fd, watch, udata)` and `sceKernelDeleteFileEvent(eq, fd)` take the [OpenOrbis](https://github.com/OpenOrbis/OpenOrbis-PS4-Toolchain/blob/0a1aaf9d/include/orbis/libkernel.h#L35) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0/src/SharpProspero/Interop/Kernel/KernelEqueue.cs#L164) signatures; `watch` is taken as the `fflags` and the event is added with `EV_CLEAR`, neither confirmed on a title
@@ -108,6 +106,7 @@
 - [sceKernelWriteThrottlingStatus](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) reports no write throttling: the host SSD has no write budget, so the first qword of the 32-byte status is set to `UINT32_MAX` and the rest is zeroed. PPSA17221 reads only that qword: it multiplies it by 64 KiB and compares the product with byte thresholds up to 0x4AF00000 to pick one of five tiers. When the call fails the title assumes 0x4B000001 bytes, which selects the same top tier as `UINT32_MAX`. What the value measures on hardware (a remaining budget or a rate) and the meaning of the other three qwords are unknown
 - [Windows directory descriptors](../../../core/libs/prx/libkernel/File/src/DirectoryDescriptor.cpp) (libkernel) take one snapshot of the directory, on the first `getdents`, `getdirentries` or non-zero `lseek` (`SEEK_SET` or `SEEK_CUR`), and keep it until it is discarded; `lseek` to offset 0 only discards the snapshot, and the next read lists the directory again, so every rewind costs O(entries) on the next read. `lseek` takes the offset as an entry index and `SEEK_CUR` with offset 0 only reports the index. `SEEK_END` throws, where the NUL descriptor used to return 0, because FreeBSD defines it relative to the directory size, which is not modelled. A negative result returns `EINVAL` and a `SEEK_CUR` offset that overflows returns `EOVERFLOW`, as FreeBSD `vn_seek` reports them. Names whose UTF-8 encoding exceeds the one-byte `d_namlen` limit are not representable in this guest directory-record layout: `getdents` returns `ENAMETOOLONG` without consuming the entry. Repeated calls therefore report the same error and entries after that name cannot be reached through this descriptor; FreeBSD's `getdents` behavior for host filenames that exceed its `MAXNAMLEN` is not verified. `getdirentries` still reports 0 through `basep` instead of the position of the block it read, so only 0 and values returned by `lseek` are valid offsets; FreeBSD offsets are filesystem cookies
 - [/dev/random and /dev/urandom](../../../core/libs/prx/libkernel/File/src/RandomDevice.cpp) (libkernel) opened for reading return a descriptor backed by the host null device whose reads are filled with host OS entropy (`getentropy`, `rand_s` on Windows); both paths behave the same, never block, and positioned reads ignore the offset (FreeBSD `random(4)`). Only the exact paths are recognised, `fstat`, `lseek` and `mmap` see the null device, and opening them for writing throws
+- [pthread_mutexattr_getpshared and pthread_mutexattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Mutex.cpp) (libkernel) support process-private mutexes. Setting `PTHREAD_PROCESS_SHARED` returns `ENOTSUP` because mutexes use process-local host objects; no attribute is changed on failure. Values 0 and 1 and guest error 45 follow FreeBSD's [pthread.h](https://github.com/freebsd/freebsd-src/blob/main/include/pthread.h) and [errno.h](https://github.com/freebsd/freebsd-src/blob/main/sys/sys/errno.h); the unsupported-sharing error follows [pthread_mutexattr_setpshared](https://man7.org/linux/man-pages/man3/pthread_mutexattr_getpshared.3.html). PS5 shared-mutex behavior and invalid-attribute error precedence are unverified.
 - [pthread_attr_getinheritsched, pthread_attr_setinheritsched, pthread_attr_getscope, pthread_attr_setscope, pthread_attr_getstackaddr](../../../core/libs/prx/libkernel/Pthread/Posix/Attr.cpp) (libkernel) follow FreeBSD 11 libthr ([thr_attr.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_attr.c), [thr_create.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_create.c)), not measured on the console: the scope defaults to `PTHREAD_SCOPE_SYSTEM` (2), only it and `PTHREAD_SCOPE_PROCESS` (0) are accepted and other values return `EINVAL`, and an inherit value other than `PTHREAD_INHERIT_SCHED` (4) or `PTHREAD_EXPLICIT_SCHED` (0) returns `ENOTSUP`. `pthread_attr_getstackaddr` returns the configured stack address pointer (null by default). A null output of `pthread_attr_getinheritsched` throws, since libthr writes through it unchecked. A thread keeps the scope it was created with, taken from the creating thread under `PTHREAD_INHERIT_SCHED`, and `pthread_attr_get_np` and `scePthreadAttrGet` report it, but every guest thread is a host thread at system scope, so process scope changes nothing
 - [Shared memory](../../../core/libs/prx/libkernel/File/src/SharedMemory.cpp) (libkernel) on Linux implements anonymous and named objects, bounded descriptor writes and seeks, and `shm_unlink` with effective read/write permission checks from FreeBSD 11. Named paths up to 1023 bytes use `/anyps5-shm-` plus SHA-1; collisions are not detected, and the namespace is shared across processes in the host mount namespace. Named creation applies the guest umask without changing the host mask. Linux procfs and `/dev/shm` are required. Operations use an advisory directory lock; external host operations bypass it, unrelated objects serialize, and descriptor operations require two spare host descriptors and compare device/inode with the initial descriptor identity on both the pinned-object and ordinary-file fallback paths. [Guest mappings](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) support shared and private mappings of these descriptors through the allocation tracker and pin a duplicate descriptor during validation and mapping; mapping requires one spare host descriptor; file-backed mappings use the write-watch scan fallback because aliases and descriptor writes bypass per-mapping tracking. Named objects and file-backed mappings on Windows remain unsupported. Invalid non-null name pointers, console behaviour and title compatibility remain unverified.
 - [sceKernelAddReadEvent and sceKernelAddWriteEvent](../../../core/libs/prx/libkernel/Equeue/Equeue.cpp) (libkernel): a write event reports the socket's send buffer size (`SO_SNDBUF`) in `data`, not the free space left in it, as Windows has no query for that space. Only guest sockets are supported; other descriptors and a low watermark above 1 throw

 - [sceKernelWriteThrottlingStatus](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) reports no write throttling: the host SSD has no write budget, so the first qword of the 32-byte status is set to `UINT32_MAX` and the rest is zeroed. PPSA17221 reads only that qword: it multiplies it by 64 KiB and compares the product with byte thresholds up to 0x4AF00000 to pick one of five tiers. When the call fails the title assumes 0x4B000001 bytes, which selects the same top tier as `UINT32_MAX`. What the value measures on hardware (a remaining budget or a rate) and the meaning of the other three qwords are unknown
 - [Windows directory descriptors](../../../core/libs/prx/libkernel/File/src/DirectoryDescriptor.cpp) (libkernel) take one snapshot of the directory, on the first `getdents`, `getdirentries` or non-zero `lseek` (`SEEK_SET` or `SEEK_CUR`), and keep it until it is discarded; `lseek` to offset 0 only discards the snapshot, and the next read lists the directory again, so every rewind costs O(entries) on the next read. `lseek` takes the offset as an entry index and `SEEK_CUR` with offset 0 only reports the index. `SEEK_END` throws, where the NUL descriptor used to return 0, because FreeBSD defines it relative to the directory size, which is not modelled. A negative result returns `EINVAL` and a `SEEK_CUR` offset that overflows returns `EOVERFLOW`, as FreeBSD `vn_seek` reports them. Names whose UTF-8 encoding exceeds the one-byte `d_namlen` limit are not representable in this guest directory-record layout: `getdents` returns `ENAMETOOLONG` without consuming the entry. Repeated calls therefore report the same error and entries after that name cannot be reached through this descriptor; FreeBSD's `getdents` behavior for host filenames that exceed its `MAXNAMLEN` is not verified. `getdirentries` still reports 0 through `basep` instead of the position of the block it read, so only 0 and values returned by `lseek` are valid offsets; FreeBSD offsets are filesystem cookies
 - [/dev/random and /dev/urandom](../../../core/libs/prx/libkernel/File/src/RandomDevice.cpp) (libkernel) opened for reading return a descriptor backed by the host null device whose reads are filled with host OS entropy (`getentropy`, `rand_s` on Windows); both paths behave the same, never block, and positioned reads ignore the offset (FreeBSD `random(4)`). Only the exact paths are recognised, `fstat`, `lseek` and `mmap` see the null device, and opening them for writing throws
-- [pthread_mutexattr_getpshared and pthread_mutexattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Mutex.cpp) (libkernel) support process-private mutexes. Setting `PTHREAD_PROCESS_SHARED` returns `ENOTSUP` because mutexes use process-local host objects; no attribute is changed on failure. Values 0 and 1 and guest error 45 follow FreeBSD's [pthread.h](https://github.com/freebsd/freebsd-src/blob/main/include/pthread.h) and [errno.h](https://github.com/freebsd/freebsd-src/blob/main/sys/sys/errno.h); the unsupported-sharing error follows [pthread_mutexattr_setpshared](https://man7.org/linux/man-pages/man3/pthread_mutexattr_getpshared.3.html). PS5 shared-mutex behavior and invalid-attribute error precedence are unverified.
+- [pthread_mutexattr_getpshared and pthread_mutexattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Mutex.cpp) (libkernel) store and report private or shared attributes, following FreeBSD 11 libthr [thr_mutexattr.c](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libthr/thread/thr_mutexattr.c). Invalid values return `EINVAL` without changing the attribute. Guest threads execute in one host process; sharing mutexes across processes is not modeled. Console behavior and invalid-attribute error precedence are unverified.
 - [pthread_attr_getinheritsched, pthread_attr_setinheritsched, pthread_attr_getscope, pthread_attr_setscope, pthread_attr_getstackaddr](../../../core/libs/prx/libkernel/Pthread/Posix/Attr.cpp) (libkernel) follow FreeBSD 11 libthr ([thr_attr.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_attr.c), [thr_create.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_create.c)), not measured on the console: the scope defaults to `PTHREAD_SCOPE_SYSTEM` (2), only it and `PTHREAD_SCOPE_PROCESS` (0) are accepted and other values return `EINVAL`, and an inherit value other than `PTHREAD_INHERIT_SCHED` (4) or `PTHREAD_EXPLICIT_SCHED` (0) returns `ENOTSUP`. `pthread_attr_getstackaddr` returns the configured stack address pointer (null by default). A null output of `pthread_attr_getinheritsched` throws, since libthr writes through it unchecked. A thread keeps the scope it was created with, taken from the creating thread under `PTHREAD_INHERIT_SCHED`, and `pthread_attr_get_np` and `scePthreadAttrGet` report it, but every guest thread is a host thread at system scope, so process scope changes nothing
 - [Shared memory](../../../core/libs/prx/libkernel/File/src/SharedMemory.cpp) (libkernel) on Linux implements anonymous and named objects, bounded descriptor writes and seeks, and `shm_unlink` with effective read/write permission checks from FreeBSD 11. Named paths up to 1023 bytes use `/anyps5-shm-` plus SHA-1; collisions are not detected, and the namespace is shared across processes in the host mount namespace. Named creation applies the guest umask without changing the host mask. Linux procfs and `/dev/shm` are required. Operations use an advisory directory lock; external host operations bypass it, unrelated objects serialize, and descriptor operations require two spare host descriptors and compare device/inode with the initial descriptor identity on both the pinned-object and ordinary-file fallback paths. [Guest mappings](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) support shared and private mappings of these descriptors through the allocation tracker and pin a duplicate descriptor during validation and mapping; mapping requires one spare host descriptor; file-backed mappings use the write-watch scan fallback because aliases and descriptor writes bypass per-mapping tracking. Named objects and file-backed mappings on Windows remain unsupported. Invalid non-null name pointers, console behaviour and title compatibility remain unverified.
 - [sceKernelAddReadEvent and sceKernelAddWriteEvent](../../../core/libs/prx/libkernel/Equeue/Equeue.cpp) (libkernel): a write event reports the socket's send buffer size (`SO_SNDBUF`) in `data`, not the free space left in it, as Windows has no query for that space. Only guest sockets are supported; other descriptors and a low watermark above 1 throw

It waits only while the thread is inside winpthreads or restoring a context through `NtContinue`, and throws if that lasts 1 s, so a handler that calls into other host code the thread was interrupted in, such as the C runtime's heap or a lock of the emulator, can deadlock on it or reenter it

 - [sigpending](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) reports the intersection of the process-wide pending set of `sigtimedwait` and the blocked mask of `_sigprocmask`, as FreeBSD's `sys_sigpending` intersects the pending list with `td_sigmask`, and returns -1 with `EFAULT` for a null set. Because `_sigprocmask` keeps only the first 32 signals, signals 33 to 128 are never blocked and never appear in the set, and setting `SIG_IGN` (or `SIG_DFL` on a signal whose default action is to ignore) does not clear a signal that was already marked pending.

A null entry crashed the payload and still throws. Joining the calling thread returns `EDEADLK` and a zeroed attribute creates a default thread, as on the console. `scePthreadDetach` on a joined thread answers `EINVAL`, as FreeBSD does on a thread that is not joinable; the console answer for a detach after a join is unverified. A detached thread is still released when it ends, so joining it after it ended reads freed memory. A handle value copied to a second storage and joined there retains the object under the original storage key, so a later `scePthreadCreate` over that original storage releases an object the copy still points at, and the copy reads freed memory
 - [Thread cancellation](../../../core/libs/prx/libkernel/Pthread/src/Thread.cpp) (libkernel) follows FreeBSD libthr (states and types 0/1 and 0/2, `PTHREAD_CANCELED` 1, the `_pthread_cleanup_info` node layout), not measured on the console. A request is acted on only in `scePthreadTestcancel`, the condition variable, `sem` and `scePthreadSem` waits, `scePthreadJoin` and the sleeps, and their POSIX names; file and socket calls are not cancellation points. A sleep is not interrupted: the thread exits when it ends. The asynchronous type acts like the deferred one, except at the two set calls.
 - [cpuset_setaffinity](../../../core/libs/prx/libkernel/Pthread/Posix/Thread.cpp) (libkernel) - only the calling thread or the calling process is handled; other levels (ROOT/CPUSET), other scopes (CPUSET/JAIL) and other threads throw as unmodelled, invalid levels or scopes return `EINVAL` and unknown thread or process IDs return `ESRCH`, following FreeBSD's `cpuset_setaffinity`. Bits outside `sceKernelGetAvailableCpumask` are dropped, and a mask with none of those bits fails with `EDEADLK`, as FreeBSD does when the new set has no CPU in common with the parent set
 - [cpuset_getaffinity](../../../core/libs/prx/libkernel/Pthread/Posix/Thread.cpp) (libkernel) - only the calling thread or the calling process is handled; other levels (ROOT/CPUSET), other scopes (CPUSET/JAIL) and other threads throw as unmodelled, invalid levels or scopes return `EINVAL` and unknown thread or process IDs return `ESRCH`, following FreeBSD's `cpuset_getaffinity`. For the process the mask is the union of the affinities of the live guest threads, as [FreeBSD 11.4](https://github.com/freebsd/freebsd-src/blob/d106002967eff712894ab8b5337bbbff106ce5e0/sys/kern/kern_cpuset.c#L1150-L1156) ORs the mask of every thread in the process; threads the guest did not create through libkernel are not included, and the console result is unverified

 - [environ](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - data export pointing to a fixed empty environment so titles that import it load; it is not the environment libc's `getenv` reads, so it lists none of those variables and `setenv`/`putenv` changes do not appear in it
 - [seteuid, setegid, setuid, setreuid, setregid, setgroups, getgroups](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - the guest process is assumed to run as root, with real, effective and saved user and group ids 0. As in FreeBSD's `sys_seteuid`, `sys_setegid`, `sys_setuid`, `sys_setreuid` and `sys_setregid`, id 0 (or -1 for an unchanged `setreuid`/`setregid` id) is then accepted without a privilege check and changes no credential, so 0 is returned; any other id would change an id, which is not modelled, and throws. `setgroups` keeps the supplementary group list as `kern_setgroups` does (`NGROUPS_MAX` 1023, an empty list leaves the effective group as the only entry, a first entry other than 0 would change the effective group and throws) and `getgroups` reports it. The ids and privileges a title has on a console are unverified
 - [pthread_barrierattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Barrier.cpp) (libkernel) - PTHREAD_PROCESS_SHARED is accepted on the assumption that the console follows FreeBSD 11.0 libthr, which accepts it (9.0 rejects it with EINVAL); unverified on hardware. Guest code runs in one process, so a shared barrier behaves as a private one
-- [pthread_getname_np](../../../core/libs/prx/libkernel/Pthread/Posix/Thread.cpp) (libkernel) - a thread that has already been joined returns `ESRCH` (3) on a PS5 (firmware 13.60), but its object is freed after the join here, so the pointer cannot be told apart from a live thread and its name is read as for a live one
+- [pthread_getname_np](../../../core/libs/prx/libkernel/Pthread/Posix/Thread.cpp) (libkernel) - a thread that has already been joined returns `ESRCH` (3) and its output buffer is left untouched, as measured on a PS5 (firmware 13.60) by the author of this entry; since [#4481](https://github.com/boykopovar/AnyPS5/pull/4481) the joined thread's object is retained, so the posix wrapper answers `ESRCH` for it instead of reading the retained name. A null name buffer is answered with `EFAULT` before that, an order the console table does not measure. The SCE sibling `scePthreadGetname` has no measured joined-thread behaviour on the console and still reads the retained object's name, so it is unchanged, as is the pre-existing dangling case of a thread that ended detached (its object is released at exit; see the scePthreadJoin entry)
 - [sceKernelGetOperationMode](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - the signature `(int* mode, int* submode)` comes from PPSA12544, which logs both values after the call and ignores the result. A homebrew payload on a PS5 (firmware 13.60) reads mode 2 and submode 0, nothing else is written, and the result register holds no status, so the function is taken to return nothing. Whether a title process reads the same values is unverified. Null outputs throw
 - [sceCoredumpGetStopInfoCpu](../../../core/libs/prx/libkernel/System/src/Coredump.cpp) (libkernel) takes `(void* info, size_t size)` as in the [Orbital type database](https://github.com/AlexAltea/orbital/blob/cc408367da6a6ebbf5ac1ac559fefeadc73b2831/tools/ida/db_types.json); the 16-byte, 8-byte-aligned block follows [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Kernel/KernelSystem.cs), which places coredump reads inside the handler. The handler is never invoked here, so a well-formed request returns `NOT_IN_COREDUMP_HANDLER` without reading or writing the block. Its value `0x81180003` follows [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/e0a466753a1aacbc8db8253be685bf7ab4d9daae/src/core/libraries/kernel/coredump/coredump_error.h) and the NHL 27 (PPSA34063) call site reported in [#4275](https://github.com/boykopovar/AnyPS5/discussions/4275), not a PS5 measurement. The console validation order is unverified: null, unaligned or wrapping buffers and sizes other than 16 throw instead of guessing an argument error. Information from an active coredump handler remains unsupported
 - [sceCoredumpAttachMemoryRegion, sceCoredumpAttachUserMemoryFile](../../../core/libs/prx/libkernel/System/src/Coredump.cpp) (libkernel) - both take `(uint32_t userValue, const void* mem, size_t size)`: for the first, the IDA type database of [Orbital](https://github.com/AlexAltea/orbital/blob/master/tools/ida/db_types.json) and the [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/Kernel/KernelSystem.cs) bindings agree; the second has only SharpProspero (the PS4 5.05 firmware does not export it, so Orbital has no entry) and is described there as attaching the region as an unnamed user file. Not confirmed on a title; the RED engine's PS4 crash handler ([Vangaurd](https://github.com/vurimad/Vangaurd/blob/main/source/imported/common/redSystem/src/errorHandlerImplErrorHooksOrbis.cpp)) calls the sibling `sceCoredumpAttachMemoryRegionAsUserFile(999, buffer, bytes, name)` from inside its handler. Attaching belongs inside the core dump handler, which the system runs on its own thread after the process stops (SharpProspero's remark, the RED engine's usage and `SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER`, "function was not called from registered core dump handler", in the Vita's SceCoredump error table, [RivetDB](https://github.com/CreepNT/RivetDB/blob/master/rivetdb.json)). The handler is never invoked here, so every call is outside it and returns that error; nothing is recorded, as there is no dump to attach to. Its value `0x81180003` comes from shadPS4 (PS4), not confirmed on a PS5: [fpPS4](https://github.com/red-prig/fpPS4/blob/master/kernel/ps4_libkernel.pas) has `NOT_REGISTERED` 0x81180001 and `ALREADY_REGISTERED` 0x81180002, shadPS4's `coredump_error.h` has `NOT_IN_COREDUMP_HANDLER` = 0x81180003, and the Vita table numbers `PARAM` 0, `NOT_REGISTERED` 1, `ALREADY_REGISTERED` 2 and `NOT_IN_COREDUMP_HANDLER` 3. Whether the console checks the region before the calling context is unknown, so a null, empty or wrapping region throws. `userValue` is not interpreted; SharpProspero names its bits 31 and 30 as truncation flags for the user file variants

 ### Silent stubs
 
+- [sceVideoOutSetFlipRate](../../../core/libs/prx/libSceVideoOut/src/Output.cpp) stores a rate of 0, 1 or 2 and returns `VIDEO_OUT_ERROR_INVALID_VALUE` for any other rate. PPSA13356 calls it with 60; whether the console accepts that value or returns this error is unverified
 - [sceVideoOutOpen](../../../core/libs/prx/libSceVideoOut/src/Output.cpp) validates the priority and CPU affinity that the open param requests for the VideoOut service thread but does not apply them: the port's present and vblank threads are host threads, and guest priorities and affinities do not reach host scheduling
 - [sceVideoOutAddVrrStatusFlagsPrivilege](../../../core/libs/prx/libSceVideoOut/src/Output.cpp) returns 0 and does nothing: the host output has no VRR state to report. The name comes from an assert message in a title that requires `SCE_VIDEO_OUT_OK`; the NID hashes to it, the arguments are unknown (it is called without any)
 - [sceVideoOutVrrPegToFixedRate, sceVideoOutVrrUnpegFromFixedRate](../../../core/libs/prx/libSceVideoOut/src/Output.cpp) (libSceVideoOut) - PPSA05684 passes the handle to both, two further zero arguments to `sceVideoOutVrrPegToFixedRate`, and ignores the results. The meaning of those two arguments is unknown, so only zeros are accepted. VRR is not modelled and the output always runs at a fixed rate, so both calls only validate the handle and return 0

Subject: [PATCH 0023/1000] fix(savedata): return a parameter error from
 sceSaveDataMount3 for an invalid directory name

An unterminated or empty directory name, "." or "..", or a name
containing "/", "\" or ":" now returns SAVE_DATA_ERROR_PARAMETER and
leaves the mount result unchanged. The SDK 12.000 reference lists that
code for an invalid parameter of sceSaveDataMount3, KytyPS5's
SaveDataMount3 returns it for an invalid name, and sceSaveDataDelete
and sceSaveDataConvert already return it here for the same check.
It threw before, which stopped Minecraft Preview (PPSA19639) on
entering a world.

The Mount3 trace now prints at most the 32 bytes of the directory name
and the 16 bytes of the mount point, since both can be unterminated
when the mount fails.

Subject: [PATCH 0024/1000] fix(libkernel): commit a reserved host stack before
 protecting it

Guest threads run on host stacks that Windows reserves (0x210000 bytes
by default) and commits on demand. Resident Evil Village protects one
thread's whole host stack with 0xc2 at startup while its lowest 0xd000
bytes are still only reserved, so the Windows mprotect emulation threw.
When such a stack sat inside the arena bounds as a host region, the call
took the arena commit path and failed to split a placeholder that was
never one.

Commit the reserved pages of a host range before protecting it, and only
use the arena commit for ranges the arena owns.

Subject: [PATCH 0026/1000] fix(ci): count only earlier open PRs in the intake
 limit

pr-intake runs once per opened PR, and each run lists every open PR by
the author. When an author opens several PRs within seconds, every run
sees all of them and closes its own, so a newcomer opening two PRs at
once loses both, and an author with one merge opening 21 loses all 21.
On opened events the limit now counts only lower-numbered PRs, so the
earliest ones stay open and only the PRs over the limit are closed.
Reopened events still count every open PR, as before.

Subject: [PATCH 0027/1000] fix(ci): clear the stale label once a PR is rebased

Stale conflicts runs actions/stale with only-pr-labels: needs rebase.
actions/stale skips any PR without all only-labels before it looks at
remove-pr-stale-when-updated, so after a rebase removes needs rebase the
PR is never processed again and keeps its stale label for good. A step
before actions/stale now removes stale from open PRs that no longer
carry needs rebase.

Subject: [PATCH 0029/1000] fix(libSceFiber): map fiber host stacks on hosts
 without MAP_STACK

AllocateHostStack passes MAP_STACK to mmap. The macOS SDK defines
MAP_NORESERVE but not MAP_STACK, so Export.cpp does not compile there.
Build the flags in a local variable and add MAP_STACK only where the
host defines it. Linux keeps the same flags.

Subject: [PATCH 0030/1000] fix(tools): count tests registered per
 configuration as run

Ninja Multi-Config writes one add_test per configuration and a final NOT_AVAILABLE one for the same name. The audit kept only the last, so every test executable was reported as never run.

Subject: [PATCH 0031/1000] fix(agc): bind a read-only V# over the cached
 address space through the region that holds it

Since the cached address space keeps a read-only V# that only partly
overlaps its base regions (readsOverBase), a build's own regions can
overlap base regions. UploadPrepare merges overlapping own views, so a
merged region can begin before the base region that holds a view's first
byte. owner() still took whichever candidate began later, so Descriptor
bound such a view through one base region it does not fit:

  guest buffer view 0x1f0494592c+0x1b2190 exceeds its GPU owner
  0x1f04940000-0x1f04950000 (buffer 0, direct 1, mirror 0)

owner() now takes the range's end and prefers the candidate that holds
the whole range. When both or neither do, it keeps the previous rule.
Every caller already knew the end it passes.

Subject: [PATCH 0033/1000] fix(agc): queue 0 waits instead of spinning when
 every queue is idle

With every queue idle, no completions pending and no storage results
pending, queue 0 took the idle branch, found nothing to store
(idleResultsPending() is false since #4410 added the AnyPending() check)
and re-checked at once: the condition kept for "nothing was stored"
continued the loop whenever storeIdleResults was false. Queue 0 never
reached its wait and spun on the driver mutex, a full host core for as
long as the GPU sat idle.

Queue 0 now re-checks only when storage results became pending since the
check or a queue finished work (idle epoch changed); otherwise it waits
for a submission or the next idle epoch as before.

Test: agc_driver_queue_zero_idle_wait submits a NOP on queue 0 and
requires queue 0 to go dormant with nothing pending.

Past the threshold Sony's error helper sets `errno` to `ERANGE` before returning `x * 1e37`; msun itself sets no `errno`. That code, run on a Windows host, gives the same bits as this implementation for every finite argument up to the threshold, of both signs; it was not run on Linux.

For |x| > 1, the infinities and NaN, Sony's error helper raises `FE_INVALID` and sets `errno` to `EDOM` before returning `(x - x) / (x - x)`, so a NaN argument also sets `EDOM`; msun itself sets no `errno`. 20 million random arguments in (-1, 1) give the same bits as that code run on a Windows host. The result needs the x87 precision control at 64 bits, as FreeBSD amd64 starts threads (control word `0x37f`), but guest threads do not set it: on Windows a thread started by `_beginthreadex` runs at 53 bits (`0x27f`), where `asinl(0.75)` returns mantissa `0xd91a98ae3406e000` instead of `0xd91a98ae3406e041`.

For |x| > 1, the infinities and NaN, Sony's error helper raises `FE_INVALID` and sets `errno` to `EDOM` before returning `(x - x) / (x - x)`, and for |x| = 1 it raises `FE_DIVBYZERO` and sets `errno` to `ERANGE` before returning `x / 0`; msun itself sets no `errno`. That code, run on a Windows host, gives the same bits, `errno` and floating-point exceptions as this implementation for all 2^32 arguments; it was not run on Linux.

+- [getenv, setenv, unsetenv, putenv](../../../core/libs/prx/libc/src/Environment.cpp) (libc) keep one guest environment that starts empty, like the `environ` libkernel exports, and never reads or changes the host's. A title sees only the variables it sets itself; host variables such as `HOME` and `PATH` name host paths a guest cannot use (PS5MC, PPSA99420, exits with `XBMC_Run returned -1` when it gets the host's `HOME`). Whether the console starts a title with any variables set is not measured
 - On macOS the [write watch](../../../core/libs/prx/libc/src/GuestWriteWatch.cpp) write-protects watched pages and records the first write to each from a SIGBUS/SIGSEGV handler, because macOS has no counterpart to `userfaultfd` write-protect or `MEM_WRITE_WATCH`. The protection is real, so:
   - a system call that writes into a protected page fails with `EFAULT` instead of faulting. `GuestArena::HostWrite` lifts the protection for the calls it brackets (file reads and socket receives); a host call that writes guest memory without it (`clock_gettime` and the like into a watched page) fails;
   - code that changes the protection of watched pages, or maps over them, has to call `GuestWriteWatchProtectionChanged`, and code that asks the kernel for a page's protection has to ask `GuestWriteWatchProtection` first, since a watched page is read-only between a collection and the next write. Nothing calls either yet: the macOS memory paths are not in the tree;

Subject: [PATCH 0037/1000] fix(ci): label all open PRs, not only the newest
 200

The area-labels workflow listed open PRs with -L 200, so with more than 200
open PRs the older ones never entered the todo list and never got their area
labels (#3295 changes libkernel and has no libkernel label). List up to 1000;
the head -n 40 cap still bounds labeler work per run.

Subject: [PATCH 0039/1000] fix(conventions): accept Depends on answered as a
 list

The pr-template check only accepted "Depends on: #N" or "none" on the same
line, so a checklist answering it as a bulleted list failed CI although
pr_overlap reads exactly that form (test_pr_overlap_dependencies covers
"Depends on:
- #2
- #3"). Allow one list marker before the first answer;
an empty answer is still reported.

Subject: [PATCH 0040/1000] fix(relinker): report RIP-relative operands of far
 indirect CALL and JMP

DecodeInstruction returned before reading the ModRM of FF /3 and FF /5,
so a far CALL or JMP through a RIP-relative pointer had no RIP-relative
displacement. A stub that moved such a JMP copied the displacement
without relocating it.

The decoder was compared with iced-x86 (AMD decoding) over 3.99 million
encodings: every opcode of the legacy, 0F, 0F38 and 0F3A maps under 34
prefix combinations and the VEX 0F, 0F38 and 0F3A maps, each with 48
ModRM forms. Apart from this, it agrees on length, RIP-relative offset,
control flow kind and branch target for every valid Zen 2 instruction
except near branches with a 66 prefix, recorded as technical debt, and
kernel-only returns, which it treats as sequential.

Add the comparison's metadata as cases: one RIP-relative encoding per
opcode, map and immediate size, every FF /r form, and the branch forms
with their flow kind and target. The existing cases check lengths only;
a loop or jrcxz decoded as an unconditional jump passed the whole suite.

 - The executable file that [relinker](../../../core/relinker/elfpatcher/src/windows/WindowsPeWriter.cpp) generates opens a console when launched, unless it is relinked with `--windows-gui`, which selects the GUI subsystem. A GUI build started from Explorer has no standard output or error handle, so everything it prints is lost, including the entry stub's errors and crash reports (#3282).
 - Converted Windows main executables [omit `DYNAMIC_BASE`](../../../core/relinker/elfpatcher/src/windows/WindowsPeWriter.cpp) by default, not only with `--windows-fixed-base`: on the console the executable lies inside the 40-bit window that the title's own `sceLibcMspaceCreate` checks (#3043). Relocations are kept, so if `0x140000000` is taken Windows relocates the image, possibly above that window. Verified only on Windows 10.
 - [SDK memory-management syscall traps](../../../core/relinker/relinker/src/analysis/SyscallScanner.cpp) under `--trap-sdk-syscall-stubs` recognize three exact instruction sequences from [ps5-payload-dev SDK libc/mman.c](https://github.com/ps5-payload-dev/sdk/blob/12cf3dda40/libc/mman.c), observed in Nuvio Maxd 0.5.15 (PPSA99288): syscall 74 and the two syscall 477 paths, with their argument preparation and carry-flag error handling. Matching requires a decoded instruction boundary and the complete sequence inside the scanned code range. Other SDK/compiler output remains rejected. The matched syscall becomes `UD2`; this does not implement mmap or mprotect and a call still faults.
+- The [instruction decoder](../../../core/relinker/codegen/src/x86/X64InstructionDecoder.cpp) decodes a near CALL, JMP or Jcc with an operand-size prefix (`66`) as Intel does, with a 32-bit or 8-bit displacement and a 64-bit target. AMD processors, the console included, read a 16-bit displacement for `66 E8`, `66 E9` and `66 0F 80`-`8F` and truncate the target of every near branch with that prefix, rel8 forms included, to 16 bits. Compilers do not emit these forms; the relinker's length and target for them do not match the console.
 - `--to-intel` does not lower RDPRU/MCOMMIT; the [matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp) fails the relink instead.
 - The length-changing path of the [instruction rewriter](../../../core/relinker/codegen/src/x86/X64InstructionRewriter.cpp) is not used by the [converter](../../../core/relinker/codegen/src/Amd64OnlyConverter.cpp): it does not adjust data-to-code references (relocations, FDEs, jump tables) or segment sizes, so every substitution keeps the instruction length.
 - A `PT_SCE_RELRO` segment that no `PT_LOAD` covers, the PS4 layout, is [loaded](../../../core/relinker/relinker/src/parsing/ElfReader.cpp) as a read-write `PT_LOAD` and stays writable after relocation; FreeBSD rtld makes `PT_GNU_RELRO` read-only once relocation is done, and what the console does with `PT_SCE_RELRO` is not checked.

Subject: [PATCH 0041/1000] perf(recompiler): keep the vector window's
 unindexed slots out of the array

A shader with any v_movreld kept its whole relative-addressing window (167
registers in a PPSA08427 compute shader) in one Function-storage array, which
the device puts in local memory. The window array now holds only the slots the
relative accesses likely reach (from a bound analysis of their indices); every
other slot is a variable of its own the device can keep in a register. A
relative access whose index lands past the array at run time switches over
those variables, so the guess only affects speed. APS5_NO_WINDOW_NARROWING=1
turns it off.

Subject: [PATCH 0042/1000] fix(agc): find a view's region when the cached
 address space dissolves after UploadPrepare

UploadFinish dissolves the cached address space when an import was
retired after the space was built. The space's base regions are then
merged with the build's own regions, which since readsOverBase may
overlap them. owner() searched the merged list for the region with the
greatest begin, a base region of one mapping, so a read-only V# merged
into an own region that began earlier was bound through it again:

  guest buffer view 0x1f0390c1c4+0x10c1cc exceeds its GPU owner
  0x1f03900000-0x1f03910000 (buffer 0, direct 1, mirror 0)

The dissolve now notes when the merged list overlaps, and owner() then
looks back for a region that holds the whole range. The test's third
build retires the imports between UploadPrepare and UploadFinish.

Subject: [PATCH 0043/1000] test(agc): drop a shared range's backing when the
 range goes away

Each SharedRange in agc_host_import_sparse registered a pointer to its
Backing in the global list Resolve searches, and never removed it. The
ranges live on the stack of each check, so by the last check the list
held pointers into stack frames that had been reused. On this machine
Resolve matched one of them for the fourth check's range and returned
an unrelated descriptor (st_size 0, offset 46330441829925), the sparse
path was not chosen, and the check failed with "a failure at
vkQueueBindSparse after the sparse path was chosen did not throw".
Whether it passes depends on what the compiler leaves in those frames.

The range now removes its Backing when it is destroyed. The test passes
20 of 20 here, and fails again when a vkQueueBindSparse failure no

Subject: [PATCH 0044/1000] fix(relinker): move legacy CMPSS and CMPSD out of
 line for Rosetta

The Rosetta split covered only VEX scalar compares. #5642 measured the
same lost load after legacy CMPSS and CMPSD, and the decoder already
hands them to the matcher with the right length and RIP offset.

Recognise F3 or F2, segment overrides and an optional REX before
0F C2 /r ib, with the same predicate rule as the VEX forms. A 66, 67 or
LOCK prefix, or both F2 and F3, keeps the instruction inline as before.

Subject: [PATCH 0045/1000] fix(stubgen): report named stubs by __func__

CONTRIBUTING.md says unimplemented exports call
NotImplemented_nid_no_patch(__func__), and 362 calls in core/ do. A stub
generated for a NID with a known name passed the NID string instead,
so its log line showed tNn5WBkta60 rather than sceAmprCommandBufferNop
and the output had to be edited by hand. Named stubs now use __func__;
stubs with an unknown name keep the NID, the only identifier they have.

Subject: [PATCH 0048/1000] fix(trace_digest): print non-ASCII names on a
 legacy console

On Windows, piped or redirected output uses the ANSI code page, so a
trace whose thread or slice names are not in cp1252 (a Japanese thread
name, for example) made the markdown digest stop with
UnicodeEncodeError after the work was done. stdout is now set to UTF-8
when the tool runs from the command line, as check_conventions.py does.
The --json output was not affected because json.dumps escapes non-ASCII.

The meaning of the second argument is unknown; a value other than 0 throws, and so does a keyboard type other than 0.

PRAGMATA (PPSA02530, #5726) and Onimusha: Way of the Sword (PPSA27836) pass `0x4000000` as a constant: Onimusha calls it for every keycode from 0 to 0x8F to build a table of key names, upper-cases `a` to `z` itself and skips keycodes that fail or return 0, so that bit is ignored and the unshifted character is returned as for 0. Any other bit throws, and so does a keyboard type other than 0.

Subject: [PATCH 0050/1000] fix(libc): ignore the space and + flags for
 unsigned printf conversions

The guest formatter passed the flags of %o, %u, %x and %X to the host, and
MinGW's printf prefixes a space to %u when the space flag is set: "% u" of 5
gave " 5". C17 7.21.6.1 applies both flags to signed conversions only, and
FreeBSD 11.4 vfprintf clears the sign for every unsigned conversion (nosign).

Subject: [PATCH 0051/1000] fix(libc): keep lgamma finite for subnormal
 arguments on Windows

The MinGW-w64 lgamma overflows to infinity for nonzero |x| at or below 2^-1024. FreeBSD msun e_lgamma_r.c returns -log(|x|) for every nonzero |x| below 2^-56, so take that branch before the host function.

 - [SET_PREDICATION](../../../core/libs/prx/libSceAgcDriver/Execution/src/Pm4.cpp) (AGC driver) - boolean predication follows the AMD PM4 encoding [Mesa](https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/amd/common/sid.h) uses: operation 3 reads 64 bits and 4 reads 32 bits, and bit 8 runs predicated packets when the value is non-zero (clear: when it is zero); the bit 12 hint is ignored. The address must have its low 4 bits clear, as `sceAgcDcbSetPredication` writes it. Query predication (Z-pass, primitive count), a predicated COND_EXEC, predicated command buffer chains and flips in predicated command buffers throw
 - [NGG vertex programs on the mesh path](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - an unregistered vertex program with `PRIMGEN_EN` that uses LDS or `s_barrier` runs on the geometry (mesh) path. Each input primitive is assumed to yield at most one output primitive, the subgroup is bounded by `GE_MAX_OUTPUT_PER_SUBGROUP` as a vertex budget, and the GS/ES VGPR count checks are skipped, because the merged inputs keep their positions. Taken from the code Mesa's ACO emits for NGG culling and from PPSA59322 and PPSA99010 draws, not measured on hardware. Registered programs keep the vertex path
 - [Strided buffer overhang](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - a strided buffer descriptor that ends less than one stride past the end of the readable registered allocation holding its base is bound only up to that allocation's end, even when another readable allocation starts right there. This assumes the bytes past the end are the rounded-up `num_records` of the last record (RADV rounds it up), which no fetch inside the buffer reads; a guest that really keeps a vertex split across two adjacent allocations would read zeros for the cut tail. Taken from the RetroArch Dolphin core case in #2912, not measured on hardware.
+- [Buffer descriptors past the range limit](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - a buffer V# whose size is over `maxStorageBufferRange` is bound only up to the end of the readable registered allocation holding its base when that allocation ends before the limit, and as the empty placeholder buffer, like a null V#, when no registered allocation holds its base; a V# over an allocation that reaches the limit still throws. Titles leave such words in descriptor slots their shaders do not reach on the path taken (PPSA10528 binds `c8010002 2c6bec20 c0053c00 04000013`, about 33 TB from an address above the user address space). What the console returns for an access past the bound range is not known; here the device's robust buffer access decides. Follows the review of #3202, not measured on hardware.
 - [Zero-stride vertex fetch range](../../../core/libs/prx/libSceAgcDriver/Graphics/include/VertexInput.hpp) (libSceAgcDriver) - for a stride-0 V# with OOB_SELECT 2 the whole fetch reads memory unless NUM_RECORDS is 0; with OOB_SELECT 3 it reads zero when NUM_RECORDS is 0 and throws when the fetch only partly fits. Rules taken from the GFX10 OOB_SELECT table in Mesa [ac_descriptors.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/amd/common/ac_descriptors.c), not measured on hardware. Whether OOB_SELECT 3 checks each dword of a multi-dword fetch separately is unknown. OOB_SELECT 0 and 1 keep the structured record checks.
 - [Resource registration](../../../core/libs/prx/libSceAgcDriver/Resource/src/Registration.cpp) (libSceAgcDriver) - registration always fails with `RESOURCE_REGISTRATION_UNAVAILABLE`, so the owner and resource queries, `sceAgcDriverSetResourceUserData`, `sceAgcDriverFindResourcesPublic` and `sceAgcDriverUnregisterAllResourcesForOwner` return the same error without reading their arguments. Their parameter lists follow the libSceGnmDriver counterparts and are unverified. `sceAgcDriverGetResourceRegistrationMaxNameLength` writes 0xfc and returns 0, as [prosper](https://github.com/mattias800/prosper) does from a title's registration configuration; the `uint32_t*` parameter matches the SDK wrapper `sce::Agc::ResourceRegistration::getMaxNameLength(unsigned int*)`. sharpemu writes 256 and KytyPS5 returns `RESOURCE_REGISTRATION_UNAVAILABLE`, so the value is unverified; a null output throws
 - [sceAgcDriverRegisterMultipleResources](../../../core/libs/prx/libSceAgcDriver/Resource/src/Registration.cpp) uses the existing unavailable-registration state and leaves caller memory untouched. Its four arguments (uint32 handle output, uint32 owner, descriptor pointer, uint32 count) follow the original PPSA34502 / 01.010.000 codzm call. The caller builds 40-byte descriptors and explicitly accepts 0x8A6C9018 with an invalid output handle. Enabled registration and console argument-validation precedence are unverified.

PPSA21480 treats the code 0x8A6C9018 it returned before as fatal. Console behaviour is unverified: OpenAGC describes the function as a firmware 5.50 stub that returns 0x8A6C9018, SharpEmu returns 0

 - [Inactive vertex point size](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) - `PA_CL_VS_OUT_CNTL.USE_VTX_POINT_SIZE` is accepted for lines, triangles and rectangles with `GS_EN` and `HS_EN` clear, when polygon mode is disabled or both faces are filled. Points, patches and absent routing or rasterization registers still throw. Bit 16 selects the misc export's X component as PointSize ([AMD CIK register reference](https://www.amd.com/content/dam/amd/en/documents/radeon-tech-docs/programmer-references/CIK_3D_registers_v2.pdf), PA_CL_VS_OUT_CNTL); ignoring it for non-point rasterization follows [Vulkan PointSize](https://docs.vulkan.org/refpages/latest/refpages/source/PointSize.html). This is inferred, not measured on console hardware. XashPS5 (PPSA19111 v1.3) sets `0x01210000` on a filled triangle draw.

Subject: [PATCH 0054/1000] fix(kernel): read a zero flexibleMemorySize in
 param.json as the default budget

SONIC SUPERSTARS (PPSA06888) ships "kernel": {"flexibleMemorySize": 0},
which the parser rejected, so the title stopped before its first module
loaded. A zero size now leaves the default budget, like an absent one.

Subject: [PATCH 0058/1000] perf(shader): look up the BDA range of a user-data
 pointer once at program entry

Address-based reads whose 64-bit base is a pair of user-data registers
search the BDA table at every read, although the base is one value for
the whole draw. Where a program has two or more such reads of one base
(at most four bases, those with the most reads), the range holding the
base is now searched once at the program's entry, by the subgroup's
elected lane when the program already uses subgroup ballots. Each read
then takes one branch: when that range holds all of its bytes, and for
dword reads the device address is 4-aligned, it loads them directly;
otherwise it runs the lookup path as before, so data, faults, invocation
stops and wraparound are unchanged. Ranges ending above
0xffffffff00000000, whose base plus a 32-bit offset could wrap, and
ranges whose device addresses wrap are not used.

The direct path relies on the table being ascending and disjoint, which
the driver builds and now requires (BdaAbi::RangesOrdered).

Subject: [PATCH 0059/1000] fix(avplayer): defer loop warnings until frame
 delivery

Queue demux loop epochs and report each once when audio or video first delivers that pass. Discard pending loop boundaries on seek and restart. Add playback regressions and record unverified console callback timing.

AI-assisted: yes (Codex).

 ### Unknown function info
 
+- [AvPlayer loop warnings](../../../core/libs/prx/libSceAvPlayer/src/Source.cpp) are queued when the first audio or video frame of a loop is delivered, following [KytyPS5's playback boundary tracking](https://github.com/KytyPS5/KytyPS5/blob/a6f4e8e7f456b8697d3102823d3f16400c3e121e/src/libs/avPlayer.cpp#L1038-L1043). The console's exact callback timing is unverified. Decode-ahead does not announce a loop while the caller is consuming the previous pass.
+
 - [sceAvPlayerAddSource](../../../core/libs/prx/libSceAvPlayer/src/Source.cpp) (libSceAvPlayer) - requests up to 4 additional decode-ahead video framebuffers from the memory replacement beyond `num_output_video_framebuffers` when memory is available; the console's internal buffering behaviour is unknown
 - [sceAvPlayerStartEx](../../../core/libs/prx/libSceAvPlayer/Export.cpp) (libSceAvPlayer) - start info layout unknown; it is ignored and playback starts as with `sceAvPlayerStart`
 - [sceAvPlayerInit / sceAvPlayerInitEx](../../../core/libs/prx/libSceAvPlayer/src/Player.cpp) (libSceAvPlayer) - behaviour without a memory replacement unknown; frame and sample buffers then come from the guest heap

Subject: [PATCH 0060/1000] refactor(agc): name dbOlWdppb4o and vieBRwlh1Lw the
 _10000 interpolant mappings

The names hash to the NIDs dbOlWdppb4o and vieBRwlh1Lw that the exports
carried as sceAgcUnknownCreateInterpolantMapping and
sceAgcUnknown_vieBRwlh1Lw.

It writes the same rendering-wait packet as `sceAgcDcbWaitUntilSafeForRendering`, which the driver now accepts on compute queues too; the wait blocks only that queue's worker. Whether the console encodes the compute variant differently is not known

It uses the base branch checker and reads pull request Git objects without executing pull request code. The Conventions check runs on every pull request and fails when a rule on this page is broken.

Subject: [PATCH 0064/1000] fix(shader): keep BDA anchors exact on tables whose
 ranges overlap

The driver builds tables whose ranges ascend by begin but can overlap
(a per-build region read over the address space's ranges). A lookup
selects the last range beginning at or below an address, so the anchor's
range now ends at the next range's begin when that comes first, and the
driver requires only ascending begins (BdaAbi::RangesOrdered).

An anchor is also not used for a range longer than 2^62 bytes, whose
offset arithmetic could wrap with a positive immediate. Anchors are
counted per read site after adjacent loads are grouped and reads with
no used dwords are dropped, so a program does not search for one
effective read; read eligibility shares RoutesApertures.

Tests: the anchored test programs can replace the lookup path by a
sentinel, which shows which reads load directly; the anchor table has an
overlapping range; a recompiled compute program reads through an anchor
on the GPU.

AI-assisted: yes

Subject: [PATCH 0067/1000] fix(agc): promote a held import window to its whole
 allocation

A 64 MiB import window held by the active recorder blocked the containing import of the same registered allocation, so an address-based build copied the whole range instead. Demon's Souls then stopped after two frames: "an address-based build copies 358 MiB of 1 registered ranges, past 64 MiB".

Allow the containing import when the recorder is active; the retired window stays alive through the hold (KeepThroughHold). Cover promotion, a sync inside the hold and release after the hold's last batch.

 ### Functional
 
 - Windows direct-memory backing reserves a paging-file section. A [direct memory page](../../../core/libs/prx/libc/include/WindowsMappings.hpp) mapped at one guest address is private write-watched memory at that address and is not committed in the section; a page mapped at a second address moves its whole resident run into the section (committed there) and every address becomes a view of it, tracked by write protection. An unmapped resident page that is not all zeros is kept in a private reservation until it is mapped again. Committed section contents remain across unmap/remap and are released when the backing and its remaining views are destroyed. A host import alias over part of a resident run is refused. Linux retains its existing backing. Peak gameplay memory and Windows versions other than the tested host remain unverified.
-- [getc_unlocked, putc_unlocked](../../../core/libs/prx/libc/src/StandardStreams.cpp) (libc) - byte I/O uses the host unlocked operations; guest EOF/error flags and macro counters follow `FileStream`. Linux status queries use `feof_unlocked`/`ferror_unlocked` because [glibc `feof`](https://github.com/bminor/glibc/blob/d2097651cc57834dbfcaa102ddfacae0d86cfb66/libio/feof.c) and [`ferror`](https://github.com/bminor/glibc/blob/d2097651cc57834dbfcaa102ddfacae0d86cfb66/libio/ferror.c) can acquire the stream lock. Windows uses [the CRT no-lock byte operations](https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/fgetc-nolock-fgetwc-nolock) and `feof`/`ferror`, verified under a held stream lock on UCRT. Console behavior and other host CRTs remain unverified.

+- [fgetws, getwc, getwchar, putwc, putwchar](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - wide stream I/O encodes and decodes wide characters as UTF-8 on the underlying byte stream; `fgetws` reads characters into the destination buffer until newline or EOF and null-terminates, returning null on stream error. Console wide stream buffering and encoding details remain unverified.
 - [ftrylockfile](../../../core/libs/prx/libc/src/RuntimeSupport.cpp) (libc) - tries the host CRT stream lock that `flockfile`, `funlockfile` and each locking host stdio call on the stream take, so it returns -1 while another thread holds the stream through `flockfile` or is inside such a call, and 0 when it acquires the lock or already owns it (recursively, released by as many `funlockfile` calls), as FreeBSD 11 [`_ftrylockfile`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdio/_flock_stub.c#L89-L104) does. A libc export holds the lock only for each host call it makes, not across several host calls or while it updates the guest `FILE` prefix. Linux uses glibc `ftrylockfile`. UCRT has no try variant of `_lock_file`, so Windows calls `TryEnterCriticalSection` on the `CRITICAL_SECTION` that `_lock_file` enters, found through the private UCRT stream layout (`__crt_stdio_stream_data` in `ucrt/inc/corecrt_internal_stdio.h`, unchanged from Windows SDK 10.0.19041 to 10.0.26100); another CRT or a change of that layout breaks it. A null or closed stream throws where FreeBSD dereferences it
 - [Wide-character conversions](../../../core/libs/prx/libc/src/Multibyte.cpp) (libc) - The wide `wcsto*` functions parse the ASCII prefix of the guest string, as the C locale accepts only ASCII white space and digits. [`wcsrtombs`](../../../core/libs/prx/libc/src/Multibyte.cpp) uses the guest's single-byte C locale through `wcrtomb`; other encodings and shift states are not supported
 - [realpath](../../../core/libs/prx/libc/src/RealPath.cpp) (libc) follows FreeBSD 11's [`realpath.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libc/stdlib/realpath.c) except for symlinks. The console's guest filesystem has none, so a host symlink under the guest root is followed for existence and type but not expanded, and `..` drops the previous component lexically, as `Resolve` does for every guest path. Through a host link `linkdir -> sub/deep`, `linkdir/../x` gives `x` beside the link, not beside its target.

Subject: [PATCH 0074/1000] fix(agc): read an unnormalized sampler without a
 mip filter at its base level

A guest sampler with FORCE_UNNORMALIZED and a mip filter of none read a
multi-level texture and the driver refused it: an unnormalized sampler is
accepted on a view with several levels only when every use is image_sample_lz and
the S# has no minimum LOD and no LOD bias. Kena: Bridge of Spirits (PPSA01746)
binds such a sampler (implicit LOD, point filters, mip filter none, LOD bias 7)
to a 9-level texture and stopped with "guest texture sampled with unnormalized
coordinates is not a single-layer 1D or 2D view ...".

With the mip filter off the sampler reads only level 0, so the base-level path
the driver already has for unnormalized samplers is exact for it whatever its
uses, minimum LOD or bias. A sampler with a point or linear mip filter is
unchanged.

Measured on a PS5 (gfx1013) through a sampler descriptor rewritten to force
unnormalized coordinates, a 64x64 texture of four levels with a distinct marker
per level, coordinates in texel units:
- mip filter point, explicit LOD 0, 1, 2, 3: level 0, 1, 2, 3, 256 of 256 texels
  each, coordinates read in texel units of the selected level
- mip filter point, implicit LOD from a quad derivative of 8 texels: level 3
- mip filter none with LOD bias 7: explicit LOD 2, explicit LOD 3 and the implicit
  LOD of 3 each read level 0, 256 of 256 texels

Tested: Windows 11, MinGW-w64 GCC 15.2.0, Release, RTX 4070 SUPER.
agc_shader_memory_tests passes with the change and fails without it on the new
assertion; agc_driver_image_sample_unnormalized_tests, agc_shader_disk_cache_tests
and agc_driver_graphics_tests pass.

Subject: [PATCH 0076/1000] fix(libSceVideodec2): hold an AVC unit of parameter
 sets for the next slice

Twispero (PPSA99474) plays a Twitch stream through its own FFmpeg demuxer
and submits the H.264 sequence and picture parameter sets as an access
unit of their own, before the first slices. libavcodec rejects a packet
with parameter sets and no slice (h264 "no frame!", AVERROR_INVALIDDATA,
with or without AV_EF_EXPLODE), so sceVideodec2Decode threw "packet
submission failed" and the title stopped as soon as a stream was opened.

A unit without a slice NAL (types 1 to 5) is now kept on the decoder and
put in front of the next unit that has one, and the call returns with no
picture. sceVideodec2Reset drops what is kept.

Subject: [PATCH 0077/1000] test(libSceVideodec2): decode an AVC stream whose
 parameter sets come alone

guest_videodec2 splits the first access unit of the H.264 fixture into
its parameter sets and its slices and decodes the parameter sets as a
unit of their own: the call must succeed without a picture, and every
picture after it must still match the reference hashes. With the
previous Export.cpp the first call throws "packet submission failed".

 - [sceVideodec2CreateDecoder](../../../core/libs/prx/libSceVideodec2/Export.cpp) (libSceVideodec2) decodes HEVC (codec type 974921) and VP9 (2382845) through FFmpeg, besides H.264. The tags come from SharpProspero's `Videodec2CodecType` and EVO-PLAYER-PS5's `sce_videodec2.h`, which records them from hardware runs. HEVC input is converted from length-prefixed NAL units to Annex B as for H.264, and VP9 frames are passed through. Output is the same 8-bit NV12 for every codec; a decoder for HEVC Main10 or VP9 Profile 2 is created, but a frame deeper than 8 bits throws, since the console's 10-bit output layout is unknown, and `QueryDecoderMemoryInfo` reports the 8-bit frame size for it. `sceVideodec2GetPictureInfo` and `sceVideodec2GetAvcPictureInfo` throw for HEVC and VP9 pictures, which use other layouts (`SceVideodec2HevcPictureInfo`, `SceVideodec2Vp9PictureInfo`), and `sceVideodec2GetHevcPictureInfo` is not exported; `sceVideodec2GetVp9PictureInfo` has its own VP9 layout
 
 - [sceVideodec2GetVp9PictureInfo](../../../core/libs/prx/libSceVideodec2/Export.cpp) uses the 88-byte layout and two-pointer signature from [SharpProspero Videodec2.cs](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Video/Videodec2.cs). Frame metadata follows the [VP9 specification](https://storage.googleapis.com/downloads.webmproject.org/docs/vp9/vp9-bitstream-specification-v0.7-20170222-draft.pdf), sections 5.26 and 6.2: profile, key/intra-only flags, bit depth, color space/range, coded/render dimensions and superframe count are retained per emitted buffer. Level is 0 because the elementary stream does not signal a level; the console value is unverified. Null pointers, undersized structures and querying another codec throw; console error codes and support for other structure sizes are unknown. Existing NV12 output rejects pictures deeper than 8 bits. Superframes are submitted as individual coded frames to keep each output associated with its input metadata.

Subject: [PATCH 0079/1000] feat(libkernel): answer
 sceCoredumpGetThreadContextInfo outside the coredump handler

sceCoredumpGetThreadContextInfo takes (void* threadContextInfo,
size_t threadContextInfoSize) as in Orbital's IDA type database, and the
144-byte block of 18 64-bit registers follows SharpProspero. It answers
as sceCoredumpGetStopInfoCpu: the handler is never invoked here, so an
aligned 144-byte request returns NOT_IN_COREDUMP_HANDLER without reading
or writing the block, and null, unaligned or wrapping buffers and other
sizes throw, as the console validation order is unverified.

 ### Unknown function info
 
 - [getlogin_r](../../../core/libs/prx/libkernel/System/src/Login.cpp) (libkernel) returns the host effective account name: `GetUserNameW` as UTF-8 on Windows and `getpwuid_r(geteuid())` on POSIX. A valid account returns a name even without a login session; host `getlogin_r`, `USER` and `LOGNAME` are not consulted. The console's login name and behaviour without a session are unknown. Account lookup or encoding failures, a missing or empty account name, and POSIX account records exceeding the 16 KiB lookup buffer throw; there is no replacement name or retry. A short guest buffer returns `ERANGE` without modifying it, and a null output returns `EFAULT`.

 - [sceKernelGetSystemSwVersion](../../../core/libs/prx/libkernel/System/src/SystemConfiguration.cpp) (libkernel) reports baseline system software version `0x01000000` ("01.000.000") for ProsperoStore (PPSA99000); the console's firmware version is not modeled. Measured on PS5 firmware 13.42: record values 0, 24, 39, 40, 41, 48 and 64 in the leading 64-bit field are accepted and preserved, the 28-byte string at offset 8 and packed version at 0x24 are filled, and bytes from 0x28 onward remain untouched. This API reports "13.590.001" / `0x13590001` in that environment, while the Prospero variant reports "13.420.000" / `0x13420000`; their values must not be assumed identical. A null pointer still returns `SCE_KERNEL_ERROR_EFAULT`, which was not measured; other firmware versions and record values remain unverified.
 - [kern.rng_pseudo](../../../core/libs/prx/libkernel/System/src/SystemConfiguration.cpp) (libkernel) - `sysctlbyname` fills the whole output buffer with bytes from the host's `std::random_device` and leaves the length unchanged; a write returns -1 with `EPERM` and a call without an output buffer throws. The only caller seen is mbedTLS's `mbedtls_hardware_poll` in the catalog's ProsperoLight boilerplate, which asks for 64-byte blocks and fails if fewer come back. The console's generator, its per-call maximum and its answer to a size query are unknown
 - [sysconf](../../../core/libs/prx/libkernel/System/src/SystemConfiguration.cpp) (libkernel) - `_SC_CLK_TCK` returns 128, FreeBSD's `CLK_TCK` as its [`sysconf`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/gen/sysconf.c#L100-L101) returns it ([`time.h`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/include/time.h#L48-L54)); the console's value is not checked, and no `times` reports ticks at that rate. CPython's `posix` module stops its import with "cannot read ticks_per_second" when the value is below 1, as the Python in PS5MC (PPSA99420) does. Names other than `_SC_CLK_TCK`, `_SC_PAGESIZE`, `_SC_NPROCESSORS_CONF`, `_SC_NPROCESSORS_ONLN` and `_SC_PHYS_PAGES` fail with `EINVAL`

Not confirmed on a title; the RED engine's PS4 crash handler ([Vangaurd](https://github.com/vurimad/Vangaurd/blob/main/source/imported/common/redSystem/src/errorHandlerImplErrorHooksOrbis.cpp)) calls the sibling `sceCoredumpAttachMemoryRegionAsUserFile(999, buffer, bytes, name)` from inside its handler. Attaching belongs inside the core dump handler, which the system runs on its own thread after the process stops (SharpProspero's remark, the RED engine's usage and `SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER`, "function was not called from registered core dump handler", in the Vita's SceCoredump error table, [RivetDB](https://github.com/CreepNT/RivetDB/blob/master/rivetdb.json)). The handler is never invoked here, so every call is outside it and returns that error; nothing is recorded, as there is no dump to attach to. Its value `0x81180003` comes from shadPS4 (PS4), not confirmed on a PS5: [fpPS4](https://github.com/red-prig/fpPS4/blob/master/kernel/ps4_libkernel.pas) has `NOT_REGISTERED` 0x81180001 and `ALREADY_REGISTERED` 0x81180002, shadPS4's `coredump_error.h` has `NOT_IN_COREDUMP_HANDLER` = 0x81180003, and the Vita table numbers `PARAM` 0, `NOT_REGISTERED` 1, `ALREADY_REGISTERED` 2 and `NOT_IN_COREDUMP_HANDLER` 3. Whether the console checks the region before the calling context is unknown, so a null, empty or wrapping region throws. `userValue` is not interpreted; SharpProspero names its bits 31 and 30 as truncation flags for the user file variants

The handler is never invoked here, so both return `SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER` (0x81180003, PS4 numbering from shadPS4) and attach nothing; whether the console checks the arguments before the calling context is unknown, so a null path or name and a null, empty or wrapping region throw. An empty path or name is passed through to that error, and `userValue` is not interpreted. No title is seen calling either

Subject: [PATCH 0080/1000] perf(libc): add sub-tick spin tail to
 PreciseSleepUs and PreciseSleepUntil

- Windows (`_WIN32`): replace full-duration waitable-timer sleep in `PreciseSleepHundredNanos` and the repeated `PreciseSleepUs` call loop in `PreciseSleepUntil` with a hybrid sleep-then-spin helper (`PreciseSleepFromCounterWithTimer`) that sleeps on the thread-local high-resolution waitable timer up to a 250 us spin tail, falls back to `std::this_thread::sleep_for` if timer setup/wait fails, and finishes the remaining window using `QueryPerformanceCounter` + `YieldProcessor()` (thresholded to 200 ns and ceiling-rounded via `PreciseHundredNanosToQpcTicks` for non-10MHz QPC frequencies).
- Linux & POSIX (`!_WIN32 && !__EMSCRIPTEN__`): replace repeated `nanosleep` loop in `PreciseSleepUs` and `PreciseSleepUntil` with `PreciseSleepFromNanos` using `clock_gettime(CLOCK_MONOTONIC)`. On Linux (`__linux__`), cache `PR_SET_TIMERSLACK` (`1 ns`) once per thread (`thread_local`) and sleep via `clock_nanosleep(CLOCK_MONOTONIC, TIMER_ABSTIME)` up to a 15 us spin tail (falling back to a conservative 100 us tail if `prctl` fails; 100 us `nanosleep` tail on other POSIX platforms) before finishing with `_mm_pause()` on x86 or `std::atomic_signal_fence` on non-x86.
- Tests: expand `core/libs/tests/PreciseWait.cpp` to assert that the 31-sample median of `PreciseSleepUs(50)` stays below 90 us (which fails on `main` at ~118 us on Linux and ~518 us on Windows) and verify ceiling QPC tick conversion and timer fallbacks.

Subject: [PATCH 0082/1000] fix(tools): place an empty segment that ends a load
 segment in unwrap_self

unwrap_self refused a container when a non-load segment with no file data
sat exactly at the end of a PT_LOAD, as an empty PT_TLS does in Sifu
(PPSA03001): "segment 6 vaddr 0x88cb7a0 is in no PT_LOAD". The eboot and
36 of its 37 bundled modules carry such a segment. A segment of size zero
now matches the load segment it ends, so it is placed at that segment's end.

Subject: [PATCH 0083/1000] feat(libSceSsl): record connection verify options,
 minimum version and ALPN

sceSslEnableVerifyOption, sceSslDisableVerifyOption, sceSslSetMinSslVersion,
sceSslSetAlpn and sceSslGetAlpnSelected kept throwing because their
signatures were unknown. SharpProspero, the source already used for the
other connection functions, declares them; the signatures follow it.

The options, minimum version and ALPN list are recorded on the connection
like the verification callback; nothing reads them until sceSslConnect has
a transport. sceSslGetAlpnSelected returns null because no handshake
completes. Unknown connections and terminated contexts throw.

The PPSA07411 functional debt entry moves to libSceJson2.md, now its first
linked library.

CA queries return independently owned snapshots; unload clears active credentials while outstanding snapshots remain valid.

Invalid loads, malformed material, exhausted pools and unsupported keys throw rather than inventing console error codes. No root bundle is shipped; an empty context still returns `NOT_FOUND`. The existing null-list error, unknown-context behavior and legacy clearing of foreign raw CA lists remain unchanged. Certificate readers remain unimplemented.

Subject: [PATCH 0084/1000] fix(ngs2): return the voice-index error from
 sceNgs2RackGetVoiceHandle

An index at or beyond the rack's voice count returned through
APS5_INVALID_ARG_EX, which throws and ends the process. Heretic + Hexen
(PPSA26525) creates a one-voice reverb rack, takes voice 0 and asks for
voice 1 at start-up, so it stopped at 1.5 s on
"sceNgs2RackGetVoiceHandle: invalid argument". Return 0x804A8305 and
leave the output handle untouched, after the existing null-output and
rack-handle checks. The value follows prosper's analysis of
libSceNgs2.native.sprx; shadPS4 lists 0x804A0302 for the PS4 library.
Neither is a PS5 measurement, recorded in the technical debt.

ngs2_voiceindex creates one-voice sampler, submixer, mastering and
reverb racks and a default sampler rack, and checks the error, the
untouched output, the null-output and invalid-rack codes and that the
last valid index still resolves afterwards. It aborts on main's library
with the throw above and passes with this change.

 - [sceNgs2GeomCalcListener](../../../core/libs/prx/libSceNgs2.native/src/Geom.cpp) supports only a listener at the origin with front +Z, up +Y and flags 0. The identity matrix and preserved finite velocity and positive finite sound speed follow [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/df5b9b92be7dfd463b47756b707d6d356a9f0550/src/libs/ngs2.cpp) and [PS5PCEM](https://github.com/iStark/PS5PCEM/blob/d2534bac6325a2c61c0fa88977e5321074304484/src/hle/ngs2_geom.zig) for that case, not a PS5 measurement. Other orientations (including non-unit vectors), translations and flags throw without changing the output; the matrix convention, handedness flags and console error codes remain unverified. Nonfinite input and nonpositive sound speed also throw. Dead Cells (PPSA15552) reaches this call after the custom sampler rack in #4334, but its arguments have not been captured here. Source attenuation, panning and Doppler in `sceNgs2GeomApply` remain unimplemented
 - [NGS2 custom sampler rack](../../../core/libs/prx/libSceNgs2.native/src/Custom.cpp) (libSceNgs2.native, rack 0x4001) - implements bounded support for the custom sampler rack and its built-in module 0x13 (Custom Voice Filter), unblocking PPSA15552 (Dead Cells) startup. Structure layouts come from [shadPS4's ngs2_custom.h](https://raw.githubusercontent.com/shadps4-emu/shadPS4/main/src/core/libraries/ngs2/ngs2_custom.h) (OrbisNgs2CustomVoiceFilterParam, 40 bytes) and live trace correlation from [prosper's hle_audio.cpp](https://raw.githubusercontent.com/mattias800/prosper/main/prosper/src/hle/audio/hle_audio.cpp) (0x40001300 command and parameters like 10000.0f and 0.707f). Routes parameter updates via the 0x40001300 command family into the Biquad filter engine, supporting only filter type 1; other filter types and unmodeled configurations throw.
 - [sceNgs2VoiceGetState custom sampler](../../../core/libs/prx/libSceNgs2.native/src/Voice.cpp) (libSceNgs2.native, rack 0x4001) - only the size and one field come from a title. PPSA15552 (Dead Cells) calls it on custom sampler voices with a 48-byte buffer at two sites (eboot `0x1740f90`, `0x1741009`) and reads only the 64-bit value at offset 16: the first site keeps it and the second subtracts the kept value, so it is filled with the voice's decoded sample count. Other sizes return `INVALID_OUT_SIZE` as for the other racks. The state flags fill the common voice state; the remaining fields stay zero. shadPS4's `OrbisNgs2CustomSamplerVoiceState` is about 80 bytes and does not match the size this title passes, so the field names and the console's value are unverified

+### Functional

+- [sceNgs2RackGetVoiceHandle voice index](../../../core/libs/prx/libSceNgs2.native/src/Rack.cpp) (libSceNgs2.native) - an index at or beyond the rack's voice count returns `0x804A8305` and leaves the output handle untouched, after the null-output and rack-handle checks that keep their order and codes. The value follows [prosper's analysis of `libSceNgs2.native.sprx`](https://github.com/mattias800/prosper/blob/d61eb2c0ad2de879ef74df9c4aa050c512804a18/prosper/src/hle/audio/hle_audio.cpp#L4299) (export `MwmHz8pAdAo` at `0xfbd0`, bounds error at `0xfc73`), which also resolves the rack before the output check; [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/e6faa2e3b6794a2fa79a709352ddfccfaa817ed1/src/core/libraries/ngs2/ngs2_error.h) lists `0x804A0302` for the PS4 library. Neither is a PS5 measurement. Heretic + Hexen (PPSA26525) and STAR WARS: Dark Forces Remaster (PPSA19728) create a one-voice reverb rack, take voice 0 and ask for voice 1 at start-up, log the failure and go on

Subject: [PATCH 0087/1000] fix(libSceNet): read SO_RCVTIMEO and SO_SNDTIMEO as
 a timeval in sceNetSetsockopt

sceNetSetsockopt took the BSD timeout options, SO_SNDTIMEO (0x1005) and
SO_RCVTIMEO (0x1006), like Sony's 0x1105 and 0x1106: as an int of
microseconds read from the first four bytes. A caller passing a struct
timeval got tv_sec taken as microseconds, so {0, 100000} meant to wait
100 ms became 0 and disabled the timeout, and the receive blocked until
data came.

On the console 0x1006 takes a timeval, as FreeBSD 11.4's sosetopt does.
ProsperoLight (PPSA99002) gives it {0, 100000} through sceNetSetsockopt,
and its log from a console (firmware 12.20) shows Moonlight's receive
timing out every 100 ms before the first packet ("Received first video
packet after 400 ms"). Sony moved only these two timeval options to
0x1105 and 0x1106, as ints. On AnyPS5 the receive never times out, so
ProsperoLight's receive threads never wake when the PC stops sending and
LiStopConnection never returns: the stream screen freezes when a session
ends from the PC side. Steam Remote Play (PPSA99350) sets {0, 10000} the
same way and stays on "THE PC DID NOT ANSWER" when the PC doesn't reply.

0x1005 and 0x1006 now go through the timeval path that setsockopt() on a
libSceNet socket already uses (EINVAL for a value shorter than a timeval,
EDOM for a negative or out-of-range one). sceNetGetsockopt gives them
back as a timeval cut to the caller's length, as FreeBSD's sooptcopyout
does. 0x1105 and 0x1106 keep taking an int of microseconds.

 - [sceNetConnect to AF_UNSPEC](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) dissolves a datagram association as FreeBSD 11.4's `udp_disconnect()` does, which resets the local address to the wildcard address and keeps the port. On Linux a socket bound to an explicit port keeps its local address as well (`127.0.0.1:<port>` stays `127.0.0.1:<port>`), because a bound socket cannot be bound again; one bound to port 0 is bound again to the wildcard address with the port it had
 - [sceNetSetsockopt](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) sets `SO_RCVTIMEO` and `SO_SNDTIMEO` as the host socket's timeouts. On Windows a receive or send on a stream socket that times out fails with `ETIMEDOUT`, where FreeBSD returns `EAGAIN` or the partial count: Winsock leaves the connection in an indeterminate state after a timeout and reports no partial count ([SOL_SOCKET options](https://learn.microsoft.com/en-us/windows/win32/winsock/sol-socket-socket-options)), so FreeBSD's behaviour needs the timeout waited for without the host option. A receive on a datagram socket that times out fails with `EAGAIN`
+- [sceNetSetsockopt, sceNetGetsockopt](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) take `SO_SNDTIMEO` and `SO_RCVTIMEO` (0x1005, 0x1006) as a 16-byte `struct timeval`, as FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/d106002967eff712894ab8b5337bbbff106ce5e0/sys/kern/uipc_socket.c#L2657-L2690) do, and Sony's 0x1105 and 0x1106 as an `int` of microseconds. A [console log of ProsperoLight](https://github.com/blackbearreloaded/ProsperoLight/issues/49) (firmware 12.20) shows receives timing out every 100 ms after it gave 0x1006 a `{0, 100000}` timeval. The errors for a value shorter than a timeval (`EINVAL`) or out of range (`EDOM`), and `sceNetGetsockopt` cutting the timeval to the caller's length, follow FreeBSD's `sooptcopyin` and `sooptcopyout` and are not measured on a console
 - [sceNetGetsockopt](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) reads `SO_ERROR` from the host socket. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `sceNetConnect`; a second failure with the same code on the same socket without a `sceNetConnect` in between would be hidden.
 - [sceNetSendmsg and sceNetRecvmsg](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) copy the scatter/gather list through one host buffer and accept only the flags `sceNetSend`/`sceNetRecv` accept. Sending control data throws; a receive never returns control data (`msg_controllen` 0), since no socket option that queues it is supported
 - [MSG_DONTWAIT](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) in `sceNetSend`, `sceNetSendto`, `sceNetRecv`, `sceNetRecvfrom`, `sceNetRecvmsg` and `sceNetSendmsg` makes that one call non-blocking through the host's `MSG_DONTWAIT`, as FreeBSD 11.4's `soreceive_generic` returns `EWOULDBLOCK` for it (`sys/kern/uipc_socket.c`); the value `0x80` is FreeBSD's (`sys/sys/socket.h`) and [shadPS4's](https://github.com/shadps4-emu/shadPS4/blob/e0a466753a1aacbc8db8253be685bf7ab4d9daae/src/core/libraries/net/net_types.h#L104). Winsock has no per-call non-blocking flag, so on Windows these calls still fail with `EOPNOTSUPP` for it

Subject: [PATCH 0090/1000] fix(exports): export the PS VR2 calls
 Phasmophobia's psvr2.prx imports

PPSA09030's Media/Plugins/psvr2.prx imports sceHmd2ReprojectionGetStatus
from libSceHmd2 and sceVrTracker2GetCoordinateSystem and
sceVrTracker2GetPlayAreaBoundaryGeometry from libSceVrTracker2, so the
title does not start with the plugin loaded (discussion #4680). Declare
the three as throwing exports, like the earlier PS VR2 imports of
PPSA29866. The names resolve from the NIDs 8GkaY2B7opM, Y-3JCiU9bbU
and SCph4ZbkqzU with tools/nid_names.py; no reference gives their
signatures.

Subject: [PATCH 0092/1000] fix(libSceNet): let a datagram receive on an
 unbound socket wait on Windows

sceNetRecv, sceNetRecvfrom and sceNetRecvmsg called Winsock's receive
straight away. Winsock fails a receive on a socket with no local address
with WSAEINVAL, so on Windows the call returned EINVAL at once. On the
console the receive waits: FreeBSD 11.4's soreceive_dgram sleeps on the
receive buffer whether or not the socket has an address, returns
EWOULDBLOCK for a non-blocking socket, and a send from another thread
binds the socket so the reply can arrive.

Steam Remote Play (PPSA99350) relies on that. Its stream library opens
its discovery socket, starts receiving on a worker thread, and binds the
socket only when another thread sends the discovery broadcast. On
Windows the worker got EINVAL, took it as fatal and closed the socket
before the broadcast went out, so the title never found a PC running
Steam.

On Windows a receive on a datagram socket with no local address now
waits until a bind, connect or send gives it one, checking every 10 ms.
A non-blocking socket fails with EAGAIN at once, and the receive timeout
ends the wait with EAGAIN. An abort or close ends the wait, and the host
receive then fails as before. Once the socket has an address it is noted
as bound, so later receives skip the check, and a later sceNetBind fails
with EINVAL as it does on the console.

 socket's local address on Windows

 - [sceNetGetsockopt](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) reads `SO_ERROR` from the host socket. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `sceNetConnect`; a second failure with the same code on the same socket without a `sceNetConnect` in between would be hidden.
 - [sceNetSendmsg and sceNetRecvmsg](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) copy the scatter/gather list through one host buffer and accept only the flags `sceNetSend`/`sceNetRecv` accept. Sending control data throws; a receive never returns control data (`msg_controllen` 0), since no socket option that queues it is supported
 - [MSG_DONTWAIT](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) in `sceNetSend`, `sceNetSendto`, `sceNetRecv`, `sceNetRecvfrom`, `sceNetRecvmsg` and `sceNetSendmsg` makes that one call non-blocking through the host's `MSG_DONTWAIT`, as FreeBSD 11.4's `soreceive_generic` returns `EWOULDBLOCK` for it (`sys/kern/uipc_socket.c`); the value `0x80` is FreeBSD's (`sys/sys/socket.h`) and [shadPS4's](https://github.com/shadps4-emu/shadPS4/blob/e0a466753a1aacbc8db8253be685bf7ab4d9daae/src/core/libraries/net/net_types.h#L104). Winsock has no per-call non-blocking flag, so on Windows these calls still fail with `EOPNOTSUPP` for it
+- [sceNetRecv, sceNetRecvfrom and sceNetRecvmsg](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) on a datagram socket with no local address wait on Windows until a bind, connect or send gives it one, checking the host socket every 10 ms. Winsock fails such a receive with `WSAEINVAL`, where FreeBSD 11.4's `soreceive_dgram` waits for a datagram (`sys/kern/uipc_socket.c`). A non-blocking socket fails with `EAGAIN` at once, and the receive timeout ends the wait with `EAGAIN`; when the address comes first, the host receive that follows waits the whole timeout again, so the call can take up to twice the timeout. An abort or close ends the wait, and the host receive then fails as it did before
 - [sceNetResolverAbort and sceNetResolverStartNtoaMultipleRecords](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) follow shadPS4 ([net.cpp](https://github.com/shadps4-emu/shadPS4/blob/811bfcd7d17ed8ae975c477d9ff28abc744e1ca8/src/core/libraries/net/net.cpp), [net_resolver.cpp](https://github.com/shadps4-emu/shadPS4/blob/811bfcd7d17ed8ae975c477d9ff28abc744e1ca8/src/core/libraries/net/net_resolver.cpp)); the `(int rid, int flags)` signature of the abort also matches [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Net/Socket.cs). Unverified on hardware. Lookups run synchronously over the host resolver, which cannot be interrupted: an abort while a lookup runs on another thread returns at once, and that lookup fails with `EINTR` without writing its output only when the host call returns; the abort flags are then ignored, as shadPS4 does for a running lookup. With nothing running, abort flag 1 (NTOA preservation) or 2 (ATON preservation) makes the next `sceNetResolverStartNtoa*` or `sceNetResolverStartAton` call on that resolver fail with `EINTR`, reported by `sceNetResolverGetError`, after its arguments are checked. Unlike shadPS4, which ignores them, other abort flag bits throw, and `sceNetResolverStartNtoaMultipleRecords` throws for any flag, including async (1) and 0x10000 (IP address literals disabled), as `sceNetResolverStartNtoaMultipleRecordsEx` does
 - [sceNetResolverStartNtoa6](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) resolves a host name to its first IPv6 address through the host resolver (`getaddrinfo` with `AF_INET6`) and writes the 16-byte address; the `(rid, hostname, addr, timeout, retry, flags)` signature follows `sceNetResolverStartNtoa`. A name with no IPv6 address fails with `RESOLVER_ENODNS` (`0x804101E1`) like a failed lookup; whether the console returns IPv4-mapped addresses instead is not verified. Timeout and retry are ignored as in `sceNetResolverStartNtoa`, and any nonzero flags throw because their meaning for this call is not known. Unverified on hardware.

On RDNA2 (gfx1036) they follow the `FLOAT_MODE` f16 round and denormal fields, not the f32 round field: -1.5 * 2^-24 + 2^-126 from f32 sources (0xbfc00000, 0x33800000, 0x00800000) gives 0x8001 with f16 denormals kept and round to nearest even, 0x8000 with f16 denormals flushed and 0x8002 with f16 round toward -infinity. With f16 denormals kept, every f16 rounding mode is translated: the exact product-sum is rounded once in the mode's direction. All four modes match RDNA2 (gfx1036) on the 2,233 rows of the #2631 sweep, including `FLOAT_MODE` 0xcc (toward zero, used by ps5-opengl) and the exact cancellations toward -infinity; the PS5's gfx1013 is not measured. A result beyond 65504 becomes infinity or 65504 as IEEE 754 gives for the mode. Flushed f16 denormals still throw, and packed f16 still throws in every mode but round to nearest even with f16 denormals kept. `FP16_OVFL` set is not measured.

A signaling NaN result of `v_cubesc/cubetc/cubema_f32` is quieted by the same rule and keeps the sign the instruction gives it, measured on RDNA2 (gfx1036) in both modes. `v_add/sub/subrev/mul/fma/fmac/fmamk/fmaak/mul_legacy_f32` and `v_fma_mix_f32` with f32 sources choose their NaN result on the bits, measured over 1000 operand triples in both modes: the first NaN source in operand order after its modifiers (the subtrahend negated, as the hardware adds its negation), quieted only with IEEE=1, or the default NaN 0xffc00000 for an invalid operation; in the fma forms an invalid product (inf * 0) gives the default NaN even when src2 is a NaN, and in the legacy forms a zero factor makes the product 0 even when the other factor is a NaN (a NaN src2 still wins). `v_mad_legacy_f32` and `v_mac_legacy_f32` follow the same rule with their separately rounded product, as measured on gfx1010 (#1281, #1290): a NaN source quieted only with IEEE=1, inf - inf giving 0xffc00000, the zero rule hiding a NaN factor and a NaN src2 winning. The f16 and f64 arithmetic, `v_fma_mix_f32` with f16 sources and the separately rounded mad/mac forms (not measurable on RDNA2) follow the same rule on hardware but their NaN bits are left to the driver. `v_cvt_f16_f32`, `v_cvt_f32_f64`, `v_dot2_f32_f16`, `v_fma_mixlo_f16` and `v_fma_mixhi_f16` always quiet and `v_div_scale_f32` never does: the f32 signaling NaN 0x7f812345 as src0 or src2 gives 0x7e09 from mixlo and mixhi at IEEE=0 and IEEE=1 on RDNA2 (gfx1036), where `v_fma_mix_f32` gives 0x7f812345 at IEEE=0 and 0x7fc12345 at IEEE=1. The payload of an f16 NaN source of mixlo and mixhi is left to the driver's f16 to f32 conversion, which NVIDIA replaces.
 - [Scalar f16 add, sub, subrev and mul denormals](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follow the `FLOAT_MODE` f16 denormal field at nearest-even: bit 0 preserves inputs and bit 1 preserves the result; otherwise a denormal is flushed to its signed zero. Measured on RDNA2 (gfx1036) with IEEE=0/1 and FP16_OVFL=0/1, over 32 operand pairs in all four denormal modes, including signed zeros, denormals, minimum normals, infinities and NaNs. Multiply detects tininess after rounding to 11 significant bits with an unbounded exponent, before gradual half packing: `0x3bff * 0x0400` flushes, while `0x3c01 * 0x03ff` rounds to `0x0400` and is kept. Directed rounding and ternary arithmetic keep their previous denormal lowering. Shaders without a known float mode keep the previous lowering. Scalar `v_sub_f16`/`v_subrev_f16` share `float16Binary` with add/mul and were measured on gfx1036 over the same operand set as add (1156 non-NaN-input rows per mode); NaN result bits still depend on the driver as recorded above.
-- [f16 unary, frexp and conversion denormals](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follow the `FLOAT_MODE` f16 denormal field: `v_ceil_f16`, `v_floor_f16`, `v_fract_f16`, `v_rcp_f16`, `v_rsq_f16`, `v_sqrt_f16`, `v_log_f16`, `v_exp_f16`, `v_sin_f16`, `v_frexp_mant_f16`, `v_frexp_exp_i16_f16`, `v_cvt_norm_i16_f16`, `v_cvt_norm_u16_f16` and `v_cvt_f32_f16` flush a denormal half input to its signed zero when bit 0 is clear (0 and 2), and the f16-result ones flush a denormal half result to its signed zero when bit 1 is clear (0 and 1), after the host rounds it to half. Measured on RDNA2 (gfx1036) at IEEE=0 and IEEE=1 with denorm16 0..3 over every non-NaN f16 input (63,490 rows per mode and instruction): the only mismatches are the 1-ULP driver differences of `v_exp_f16` (2 inputs) and `v_sin_f16` (14), which are the same with denormals kept. NaN inputs are not compared. `v_ldexp_f16` shares the input rule. `v_cvt_pknorm_i16_f16` and `v_cvt_pknorm_u16_f16` are not measured and keep their previous lowering.

Shaders without a known float mode keep the previous lowering.
 - [Packed f16 NaN results](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (`v_pk_add/mul/fma/min/max_f16`) follow the hardware measured on RDNA2 (gfx1035) at IEEE=0 and IEEE=1 with f16 round-to-nearest-even and f16 denormals kept: with IEEE=1 a signaling NaN input is quieted and min/max return the other operand only for a quiet NaN; with IEEE=0 NaN inputs pass through unquieted and min/max ignore signaling. In `v_pk_fma_f16` an invalid product (inf * 0) gives the default NaN even when src2 is a NaN. A shader without a known float mode is translated as IEEE=0, the mode titles use; a mode with another f16 rounding or that flushes f16 denormals throws.
 - [f32 denormals](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follow the shader's `FLOAT_MODE` f32 denormal field (bits 5:4) when it flushes them (0, and shaders without a known float mode, as in the 0xc0 most titles use), measured on RDNA2 (gfx1035) over 1444 rows per instruction at IEEE=0 and IEEE=1. `v_add/sub/subrev/mul/mul_legacy/mullit/fma/fmac/fmamk/fmaak/min/max/min3/max3/med3/fract/floor/ceil/frexp_mant/sin/cos_f32` flush their f32 inputs and their result to a zero of the same sign (`v_mullit_f32` measured on RDNA2 (gfx1036) over 6907 rows per mode at IEEE=0 and IEEE=1, so a positive denormal src2 counts as zero); the f32 compares, `v_cvt_i32/u32/rpi_i32/flr_i32_f32`, `v_frexp_exp_i32_f32`, `v_cvt_f64_f32`, `v_cvt_f16_f32`, `v_cvt_pkrtz_f16_f32`, `v_cvt_pknorm_i16/u16_f32` and `v_cvt_pk_u8_f32` flush their f32 inputs. `v_div_scale_f32` flushes all three inputs to signed zeros, measured on RDNA2 (gfx1036) over 2744 operand triples per mode at IEEE=0 and IEEE=1 with f32 denormals flushed and kept; its scale-down behaviour and host denormal preservation remain incomplete. `v_div_fixup_f32` flushes its src1 and src2 and keeps a denormal src0 and result, measured on RDNA2 (gfx1036) over 6859 rows per mode at IEEE=0 and IEEE=1. Tininess is detected after rounding, measured on RDNA2 (gfx1036) for `v_mul_f32` and `v_mullit_f32` at IEEE=0 and IEEE=1: a product is flushed when its value rounded to 24 bits with an unbounded exponent is below 2^-126, so `0x3f7ffffe * 0x00800001` (2^-126 * (1 - 2^-46)) gives `0x00800000` and `0x3f7fffff * 0x00800000` (2^-126 * (1 - 2^-24)) gives zero. The check rounds in the f32 round mode of `FLOAT_MODE` (bits 1:0), measured in all four modes, while the products themselves are still rounded to nearest even. This applies to `v_mul_f32`, `v_mul_legacy_f32`, `v_mullit_f32`, and to `v_fma_f32`, `v_fmac_f32`, `v_fmamk_f32`, `v_fmaak_f32` and `v_fma_mix_f32` when the addend is zero; with a nonzero addend the fused result is kept, so an exact result just below 2^-126 that rounds to it is not flushed. In the three directed modes the check is computed exactly from the significands. To nearest even (0, the mode of shaders without a known float mode) one factor is multiplied by 2^64, which is exact below 2^64, and the product with the other factor is compared with 2^-62. That multiply is a plain `OpFMul` like the product, and no f32 rounding mode is requested in the SPIR-V, so the check relies on the driver rounding f32 to nearest even by default, as the products do, and a product that rounds up to 2^-126 is the emitted product. `v_fma_mix_f32` follows this rule with mixed f16/f32 sources too, measured on RDNA2 (gfx1036) with f16 in either multiplicand slot, low and high half selection, and an f32 or f16 zero addend: f32 `0x00801002` times f16 `0x3bff` gives `0x00800000` to nearest at IEEE=0 and IEEE=1, while the neighbours `0x00801001` and `0x00801003` give zero and `0x00800001`. The tiny-product boundary was also measured for both signs in all four f32 round modes at IEEE=0; f16 inputs retain their previous conversion and denormal handling. `v_fma_mixlo_f16` and `v_fma_mixhi_f16` flush their f32 sources too and keep a product below 2^-126, measured on RDNA2 (gfx1036). `v_mad_legacy_f32` and `v_mac_legacy_f32` flush their inputs, their product and their result in every mode, see its entry; their product is still checked for tininess on its exact value, so one below 2^-126 gives zero even when it rounds to 2^-126, as the console's separately rounded encoding is not measured at this boundary. Denormal modes 1 and 2 throw for the other instructions. Not covered, and not measurable on RDNA2 (no such opcodes) or not measured: `v_mac_f32`, `v_mad_f32`, `v_madak_f32` and `v_madmk_f32` (rounded separately), `v_dot2_f32_f16` and `v_div_fmas_f32` (on hardware `v_div_fmas_f32` flushes only its result), f32 interpolation and `ds_add_f32` keep the previous lowering; `ds_min/max/cmpst_f32` flush both operands by the field, see the LDS float atomics entry. With f32 denormals kept (3) the results depend on the driver's default denormal behaviour, as no `DenormPreserve` execution mode is requested; `v_ldexp_f32` and the f32 compares are the exceptions. `v_cmp_X_f32` and `v_cmpx_X_f32` compare the operands as sign-magnitude integers with the NaN cases handled apart, so a denormal is not read as zero, measured on RDNA2 (gfx1036) over 256 operand pairs per opcode at IEEE=0 and IEEE=1 with f32 denormals kept and flushed. `v_ldexp_f32` preserves subnormal inputs and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, measured on RDNA2 (gfx1036) over 2163 rows in each of the four round modes at IEEE=0 and IEEE=1. An overflow rounds like any other result (infinity, or the largest finite value when the mode rounds that sign toward zero). With f32 denormals flushed it flushes a subnormal input and result, measured over the same rows in each round mode at IEEE=0 only. A device whose driver splits `Fma` into a multiply and an add flushes a product below 2^-126 before adding a non-zero addend in `v_fma_f32` and `v_fmac_f32`: `0x1fffffff * 0x1fffffff + 0x00800000` gives `0x00800000` instead of the fused `0x00ffffff` on RADV RENOIR (Mesa 26.2.4), whose compiled shader has `v_mad_f32` and no `v_fma_f32`. [F32DenormalFlush](../../../core/libs/prx/libSceAgcDriver/tests/execution/F32DenormalFlush.cpp) accepts that sum on such a device.
 - [v_rcp, v_rsq, v_sqrt, v_log, v_exp, v_sin and v_cos](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (f32 and f16) use the driver's approximation for finite results, not the console's: the low bits can differ. Only NaN, invalid, zero and infinite results and the exact sin/cos zeros are chosen on the bits. Measured on RDNA2 (gfx1036) over every f16 input and 32,832 f32 inputs: RADV returns the hardware's bits for every input of rcp, rsq, sqrt and log and all but one of exp (f16 0x11c5, 1 ULP); NVIDIA (615.71.09) stays within 2 ULP except `v_log_f32` near 1.0 (next entry). [v_sin and v_cos](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) take the driver's sine or cosine of the radians of the exact cycle, except within 2^-12 of a turn from a zero of the function, where the result is the linear term of the exact distance to the zero: the hardware's constant 6.2831826 (0x40c90fd5) at the integers, which the hardware applies exactly to inputs below 2^-12 of a turn, and the f32 2π at the half and quarter turns, where the hardware is within 7 ULP of it. Outside those bands, a driver result more than 4 ULP from a Taylor series in turns of the exact cycle is replaced by the series, which is within 2 ULP of the true sine and cosine; the hardware is up to 9 ULP from them (gfx1035, 243,092 f32 inputs), so results stay within 13 ULP of the hardware on any driver. RADV returns the hardware's bits for every f16 input and for 32,422 sine and 32,486 cosine results of the 32,832 f32 inputs; the rest are 1 ULP off, except up to 14 ULP on either side of non-zero integers and up to 15 ULP beyond ±256 cycles, where the hardware's own reduction differs from the exact fraction, and up to 6 ULP inside the half- and quarter-turn bands. NVIDIA's own sine is within 1 ULP on 93% of the f32 inputs and up to 1,166 ULP off just outside the bands, its cosine within 163 ULP; the series replaces those results. A denormal f32 input with f32 denormals kept gives the hardware the input times 6.2831826; both hosts flush it.

 - The [output modifier](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) (`mul:2`, `mul:4`, `div:2`) follows the shader's float mode as measured on RDNA2 (gfx1035): the hardware applies it only with IEEE mode off and output denormals of the result's precision flushed (bit 1 of the `FLOAT_MODE` denormal field clear), and ignores it otherwise. On f32 results it is applied as the hardware does with f32 denormals flushed; a shader without a known float mode is translated with IEEE mode off and f32 denormals flushed, the mode titles use. On f16 and f64 results it is ignored, and it throws in the modes where the hardware applies it.
 - The [clamp modifier](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follows `DX10_CLAMP`, measured on RDNA2 (gfx1035) for f32, f16, packed f16 and f64 results at IEEE=0 and IEEE=1: with `DX10_CLAMP`=1 (and in shaders without a known float mode) a NaN result clamps to +0, including the quieted NaN that `v_pk_min_f16` and `v_pk_max_f16` return for a signaling NaN operand with IEEE=1 (measured on RDNA2 gfx1036 at both `IEEE_MODE` and both `DX10_CLAMP` settings); with `DX10_CLAMP`=0 a NaN result is written unchanged and every other value clamps to [0, 1] as before. f64 results follow the same rule on hardware, but a clamped f64 result with `DX10_CLAMP`=0 throws until it has an execution test. With `DX10_CLAMP`=0 the NaN's bits are those the translation already produces for the instruction without clamp, so where those are left to the driver (f32 and scalar f16 arithmetic) the payload is the driver's, not the hardware's input propagation. `v_dot2_f32_f16` and the integer clamps are unchanged.
 - [FP16_OVFL](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follows the shader's float mode as measured on RDNA2 (gfx1036) at IEEE=0 and IEEE=1 with f16 denormals kept and flushed: with `FP16_OVFL`=1 an f16 result that rounds to ±infinity is written as ±0x7bff unless a source operand is infinite, so `v_rcp_f16`, `v_rsq_f16` and `v_log_f16` of ±0 and `v_exp_f16` of 16 or more are clamped while an infinite input passes through, and `v_div_fixup_f16` keeps the infinity it writes for a zero denominator or an infinite numerator and clamps any other infinite quotient, a NaN one included. `v_cvt_pkrtz_f16_f32` rounds toward zero and never overflows. The sources are checked as the f32 values the translation computes with; the rule is applied to `v_fma_mix*_f16` with f32 sources and to `v_interp_p2_f16` without a measurement of infinite f32 sources or parameters. Round modes other than nearest even are not modelled, so the overflow threshold is the nearest-even one (65520).
-- [Directed f16 rounding](../../../core/shader/recompiler/Translation/src/TranslationContext/SubwordPacking.cpp) for `v_cvt_f16_f32`, `v_cvt_f16_i16`, `v_cvt_f16_u16` and `v_ldexp_f16` follows `FLOAT_MODE` bits 3:2 only when f16 denormals are preserved (bits 7:6 = 3), measured on RDNA2 (gfx1036). With f16 denormals flushed (bits 7:6 = 0), or flushed on one side (modes 1 and 2, not measured), the hardware also flushes the f16 result and the directed path does not model that, so those shaders keep round-to-nearest-even. The `clamp` modifier with directed rounding is not measured.
+- [Directed f16 rounding](../../../core/shader/recompiler/Translation/src/TranslationContext/SubwordPacking.cpp) for `v_cvt_f16_f32`, `v_cvt_f16_i16`, `v_cvt_f16_u16` and `v_ldexp_f16` follows `FLOAT_MODE` bits 3:2 in every f16 denormal mode, measured on RDNA2 (gfx1036 with f16 denormals preserved, gfx1030 in all sixteen combinations of f16 rounding and denormal mode). When bit 7 flushes f16 results, `v_cvt_f16_f32`, `v_cvt_f16_i16` and `v_cvt_f16_u16` write a zero of the result's sign for a value that, rounded in that mode with an unbounded exponent, is below 2^-14, so a value just below 2^-14 that rounds up to it stays 0x0400; `v_ldexp_f16` keeps its rule above. The `clamp` modifier is applied before the rounding. On gfx1030 every row matches: 8,996 f32 inputs around the half denormal, normal and overflow boundaries with and without `clamp`, every 16-bit integer, and 2,470 `v_ldexp_f16` operands.
 - [Comparison sampling of a color texture](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) (`image_sample_c`/`image_sample_c_lz` on a texture that is not R32 float or R16 unorm) is emulated in the shader, since Vulkan compares only depth formats: the red channel is fetched, compared and, for bilinear filtering, blended (compare, then filter). Only 2D, 2D array and cube views, float/unorm/snorm formats, wrap, clamp-to-edge and clamp-to-border addressing (border red 0 for the black borders, 1 for opaque white) and point or bilinear filtering at one level are implemented, with texel offsets added to the texel indices; LOD biases and clamps are accepted, as they cannot select another level of a single-level sample. Half-border addressing, the border color table, gradients, gathers, other dimensions, anisotropy (except on the 8-bit formats below) and mip filtering throw. Under bilinear filtering, taps past a clamp-to-border edge compare the border value and blend with the texel taps, so results near the edge depend on the filter weights. AMD documentation does not say how a color format's reference is handled: it is clamped to [0, 1] for unorm and [-1, 1] for snorm, as Vulkan does for unorm depth, and not clamped for float. 8-bit sRGB and UNORM (`Format8Srgb`, `Format8_8Srgb`, `Format8_8_8_8Srgb`, `Format8UNorm`, `Format8_8UNorm`, `Format8_8_8_8UNorm`) return 0 for every compare function, measured with `image_sample_c_lz` on gfx1035 over references -0.5..1.5 and texel codes 0..255. A bilinear cube of those 8-bit formats without `DISABLE_CUBE_WRAP`, and an anisotropic S# on them, return 0 for the same reason; float, snorm and the other unorm bilinear cubes without that bit still throw. Bilinear weights are full float, not the hardware's fixed-point subtexel weights
 - [Negative color-texture comparison wrap indices](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) (libSceAgcDriver) use explicit `OpSRem` normalization to implement modulo; the negative-offset point-wrap regression fails with direct `OpSMod` and passes with normalization on Mesa 22.3.6 llvmpipe (LLVM 15.0.6), but negative-index wrap has not been measured on PS5 hardware.
 - [Converted unorm images](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) (10_11_11_UNORM, read and written through an R32_UINT view): samples, gathers, LOD queries, 16-bit data and a DST_SEL of the missing W channel throw.

Subject: [PATCH 0097/1000] fix(tools): key compile commands relative to the
 checkout in check_compile

The key was the source path relative to the common parent of the build
directory and the source. With a build directory beside the checkout
that parent is above the checkout, so the key carried the checkout
directory name and no changed file matched. The key is now the source
path relative to the repository root.

 ### Functional
 
-- [sceNgs2RackGetVoiceHandle voice index](../../../core/libs/prx/libSceNgs2.native/src/Rack.cpp) (libSceNgs2.native) - an index at or beyond the rack's voice count returns `0x804A8305` and leaves the output handle untouched, after the null-output and rack-handle checks that keep their order and codes. The value follows [prosper's analysis of `libSceNgs2.native.sprx`](https://github.com/mattias800/prosper/blob/d61eb2c0ad2de879ef74df9c4aa050c512804a18/prosper/src/hle/audio/hle_audio.cpp#L4299) (export `MwmHz8pAdAo` at `0xfbd0`, bounds error at `0xfc73`), which also resolves the rack before the output check; [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/e6faa2e3b6794a2fa79a709352ddfccfaa817ed1/src/core/libraries/ngs2/ngs2_error.h) lists `0x804A0302` for the PS4 library. Neither is a PS5 measurement. Heretic + Hexen (PPSA26525), DOOM + DOOM II (PPSA21444) and STAR WARS: Dark Forces Remaster (PPSA19728) create a one-voice reverb rack, take voice 0 and ask for voices 1 to 3 at start-up, log the failures and go on
+- [sceNgs2RackGetVoiceHandle voice index](../../../core/libs/prx/libSceNgs2.native/src/Rack.cpp) (libSceNgs2.native) - an index at or beyond the rack's voice count returns `0x804A8305` and leaves the output handle untouched, after the null-output and rack-handle checks that keep their order and codes. The value is read from the PS5 `libSceNgs2.native.sprx` export `MwmHz8pAdAo` (firmware 10.01 at `0x11f10`, 12.70 at `0x12130`, and every module from 1.00 to 12.70 checked in [#5916](https://github.com/boykopovar/AnyPS5/pull/5916#issuecomment-6172832590)): an index at or past the rack's voice count returns it through the same error helper that answers `0x804A8010` for a null output, and the output handle is written only on success. That export also checks the rack handle before the output pointer and returns `0x804A8202` for a bad one, while this library checks the output first and returns `0x804A0261`, which does not appear in the module; that order and code are unchanged here.

Subject: [PATCH 0100/1000] feat(agc): draw a performance overlay over
 presented frames

ANYPS5_OVERLAY=1 shows frames per second over the last second, the last
frame time, a graph of the last 120 frame times with their minimum,
average and maximum, and with APS5_PROFILE_GPU and APS5_PROFILE_DRAW the
GPU and driver time per frame, in the corner ANYPS5_OVERLAY_POS names.

A 5x7 bitmap font and solid rectangles are drawn as instanced quads by one
render pass after the frame reaches the swapchain image, on the
presentation pass and the blit paths alike, in SDR and at 203 nits on an
HDR10 swapchain. The text scales with the swapchain height. While hidden,
the presentation records nothing for it.

Subject: [PATCH 0101/1000] feat(videoout): toggle the performance overlay with
 F10

TogglePerformanceOverlay is bound to F10 by default and, like
ToggleFullscreen, accepts only a keyboard key in anyps5-input.ini.

 HDR output is available on Windows only. Titles see it when the monitor showing the window runs in HDR mode (Settings > Display > Use HDR), the window's Vulkan surface offers an HDR10 (`VK_COLOR_SPACE_HDR10_ST2084_EXT`) swapchain in a 10-bit format, the instance has `VK_EXT_swapchain_colorspace` and the device `VK_EXT_hdr_metadata`. The monitor's luminance comes from DXGI; a monitor that reports no peak luminance is taken as 1000 nits peak and full-frame, 0 nits black. On Linux and other hosts the output is always SDR, because the surface's formats do not show whether the display is in HDR. A title's BT.2100 PQ display buffers then reach the display unchanged; without HDR output they are converted to SDR.

+F10 shows or hides a performance overlay over the presented image; `ANYPS5_OVERLAY=1` shows it from the first frame. `ANYPS5_OVERLAY_POS` puts it in a corner of the window: `tl` (top left, the default), `tr`, `bl` or `br`. For either variable an empty value is the same as an unset one, and any other value stops the game at its first frame with an error that names the variable. The key can be moved with `TogglePerformanceOverlay` in the [input mapping](INPUT_MAPPING.md). The text scales with the window height, at a whole multiple of its 5x7 pixel font; on an HDR10 swapchain the overlay is drawn at 203 nits.
+
+| Line | Meaning |
+|------|---------|
+| `FPS` | Frames presented per second, over the last second. |
+| `FRAME` | Time between the last two presented frames, in ms. |
+| graph | The last 120 frame times, the newest on the right. The full height is the longest of them or twice their average, whichever is larger. |
+| `MIN/AVG/MAX` | The shortest, average and longest of the 120 frame times, in ms. |
+| `GPU` | GPU time per frame over the last second, in ms: the span of each recorded batch from its first to its last command, from the timestamp queries of `APS5_PROFILE_GPU=1`. Shown only with that variable. Batches are counted when they complete, so the line trails a sudden change by up to a second. |
+| `DRIVER` | CPU time per frame over the last second, in ms, that the packet workers spent in dispatch and draw packets (the `dispatch` and `draw` time of the `[gpu] worker` line of `APS5_PROFILE_DRAW=1`). Shown only with that variable. |
+
+Times are shown with one decimal below 100 and as whole numbers above, up to 9999. While the overlay is hidden the presentation records nothing for it and the presented image is unchanged; while it is shown, one small render pass draws it over each presented frame.
+
 ### Storing GPU results at each flip
 
 GPU results in storage images and render targets stay on the GPU until something reads their memory. A title that frees such an image after waiting for its GPU work and reuses the memory can have its new data overwritten when the results are stored later ([TechnicalDebt](../dev/TechnicalDebt.md)). `APS5_STORE_AT_FLIP=1` stores every pending result when a display buffer is flipped, at the cost of one write-back per pending image and frame. Any other value stops the title at its first flip.

The pool size is the one given to `sceNpWebApi2Initialize`, and the peak and current use are 0. The error codes are unknown, so a null output or an unknown context throws

An unknown library context throws, as in `sceNpWebApi2GetMemoryPoolStats`, since its error code is unknown. The handle is not checked, as push event handles are not tracked (`sceNpWebApi2PushEventDeleteHandle` accepts any handle), and the timeout is not kept, as nothing waits on a handle offline

Subject: [PATCH 0106/1000] test(agc): skip the sparse dma-buf import tests
 when udmabuf size_limit_mb is above 1024

Both tests build a range one chunk above udmabuf's size_limit_mb. When the limit is set very high (for example to its maximum, as a workaround for a dma-buf import larger than the default 64 MB), that range is petabytes and mmap fails: agc_host_import_sparse stopped with 'cannot reserve the guest range' and agc_driver_sparse_dma_buf_import with 'cannot map the backing file'. The driver does not take the sparse path for such a limit either, so there is nothing to test; both now skip, which ctest reports as skipped.

 - [gethostname](../../../core/libs/prx/libc/src/Hostname.cpp) (libc) reports the fixed guest name `AnyPS5` without querying the host machine name. Buffer copying, null queries and `ENAMETOOLONG` follow [FreeBSD gethostname](https://github.com/freebsd/freebsd-src/blob/main/lib/libc/gen/gethostname.c); the console's configurable hostname and its integration with `sysctl` and name resolution are unverified and not implemented.
 - [wcsrtombs_s](../../../core/libs/prx/libc/src/Multibyte.cpp) (libc) follows the console's `libc.prx`, but a runtime-constraint violation only returns its error: the default handler there writes the message and a newline to `stderr` before returning, which is not done here. Conversion uses the C locale of `wcrtomb` (`MB_CUR_MAX` 1), so the path where a multibyte character does not fit the remaining space is not reached
 - [The narrow printf family](../../../core/libs/prx/libc/src/Formatting.cpp) (libc) converts 16-bit guest wide arguments to UTF-8 on both platforms, independently of the host locale. It does not use the guest's single-byte `wcrtomb`; the console's treatment of invalid UTF-16 and locale-specific encoding remains unverified. Linux retains host formatting for formats without wide arguments or `%m`, so a narrow `%p` and a NaN there still follow the host (glibc prints a null pointer as `(nil)`, where FreeBSD prints `0x0`, and a NaN with its sign, `-nan`, and with the `+` and space flags, where FreeBSD prints `nan`); argument positions above 99 (FreeBSD's `NL_ARGMAX`) throw when a format requires the guest formatter
-- [collate<char>::_Getcat](../../../core/libs/prx/libc/src/LocaleSupport.cpp) (libc) builds the facet for the C locale only and throws for any other locale name. The console's `libc.prx` stores pointers to its collation state tables at offsets 0x10 and 0x18 of the facet; ours leaves them null, as only the facet's own functions read them. `do_transform` throws for input with embedded null characters, which the console drops depending on the output buffer size. Its result capacity (`length | 15`) and the over-aligned storage of results of 4080 characters or more follow the console's `libc.prx` code and are not checked on hardware.
+- [collate<char> and collate<wchar_t> _Getcat](../../../core/libs/prx/libc/src/LocaleSupport.cpp) (libc) build the facet for the C locale only and throw for any other locale name, the wide entry point following the narrow one it sits next to. The wide facet carries the narrow vtable because [GuestLocale](../../../core/libs/prx/libc/include/GuestLocale.hpp) models one facet layout and one vtable for both element types, so a `collate<wchar_t>` comparison, transform or hash runs the narrow `do_compare`, `do_transform` and `do_hash` over the guest's 16-bit characters read as bytes; the console's `libc.prx` exports both `_Getcat` (NIDs BSVJqITGCyI and 2wz4rthdiy8) with identical 0x19d-byte bodies, believed to build the same 0x20-byte facet; the console bodies themselves are unreadable (obfuscated dynsym), the wide vtable is not reproduced here and no console run checks the two. The console's `libc.prx` stores pointers to its collation state tables at offsets 0x10 and 0x18 of the facet; ours leaves them null, as only the facet's own functions read them. `do_transform` throws for input with embedded null characters, which the console drops depending on the output buffer size. Its result capacity (`length | 15`) and the over-aligned storage of results of 4080 characters or more follow the console's `libc.prx` code and are not checked on hardware. No module of the PPSA59322, PPSA76677 or PPSA97358 dumps in this tree imports either `_Getcat`, so neither has been exercised by a title.
 - [The scanf family](../../../core/libs/prx/libc/src/Formatting.cpp) (libc), the `_s` forms included, on Linux throws for the 16-bit wide conversions (`%ls`, `%lc`, `%l[`, `%S`, `%C`): glibc would store a 32-bit `wchar_t` per character into the guest's 16-bit buffer. Windows hands `%ls`, `%lc` and `%l[` to the host, whose `wchar_t` is 16 bits
 - [The scanf family](../../../core/libs/prx/libc/include/WindowsScanning.hpp) (libc) on Windows returns 0, as C17 and FreeBSD do, when input fails after only suppressed conversions have completed (`sscanf("12", "%*d%d", &value)`). Linux hands the format to glibc, which returns `EOF` there. On Windows the host stops a `%x`, `%X`, `%i` or `%p` after the `x` of a `0x` that no hex digit follows (or that the width cuts off), and a float conversion (`%e`, `%f`, `%g`, `%a`) after the `e` of an exponent with no digits (`1e`), where C17 and FreeBSD stop before the `x` or the `e`
 - [Guest path resolution](../../../core/libs/prx/libc/src/General.cpp) falls back to ASCII case-insensitive component lookup, following [shadPS4's host filesystem](https://github.com/shadps4-emu/shadPS4/blob/945dbc3cc3eee80ac3e053b438502ed936fa6bb2/src/core/file_sys/backends/host_fs.cpp). PPSA03747 requests `Skyrim.INI`, `Data/Video` and lowercase archive/plugin names that differ from the dump's filenames. Exact host names take precedence; multiple fallback matches throw instead of selecting an arbitrary file. Existing parent names are resolved when creating a new file, and guest mount aliases use the same ASCII comparison. Results are not cached, so renames and newly created files remain visible. Unicode case folding and PS5 behaviour for case-colliding host entries are unverified; host roots are used as supplied. Explicit native Windows drive and UNC paths bypass guest parent-component validation.. A relinked module's `<name>.guest.prx` is matched the same way when the original module is not beside it: Borderlands 4 (PPSA01494) loads `/app0/prx/libRenoirCore.PS5.prx`, which it ships as `librenoircore.ps5.prx`

Subject: [PATCH 0112/1000] feat(libSceVideoOut): register PS4 display buffers

Add the PS4 functions sceVideoOutSetBufferAttribute and
sceVideoOutRegisterBuffers on top of the existing registration. The PS4
call uses the first free attribute set and returns its index. It
accepts linear A8R8G8B8_SRGB and A8B8G8R8_SRGB buffers, which map to the
PS5 B8G8R8A8 and R8G8B8A8 formats. It throws for tiled buffers, whose
PS4 layout differs from the PS5 one. Linear PS4 buffers may be 4 KiB
aligned: the OpenOrbis graphics sample places its second 1920x1080
buffer 8,294,400 bytes after the first. PS5 buffers keep the 64 KiB
rule. A handle with PS4 buffers writes the PS4 flip status (64 bytes)
and vblank status (32 bytes). Writing the 128-byte PS5 flip status into
the sample's stack structure overwrote its saved frame pointer.

 - [sceVideoOutGetBufferLabelAddress](../../../core/libs/prx/libSceVideoOut/src/Buffer.cpp) exposes a port-owned contiguous array of 16 aligned 64-bit labels and returns its count. Astro Bot PPSA21564's bundled AGC driver passes a pointer output and addresses each label at `base + index * 8`. The count, zero initialization on registration, and release of the previous displayed buffer when its replacement completes follow [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/23c41333822fe8eca4c609b43119180af63ae4ac/src/core/libraries/videoout/video_out.cpp) and its driver; PS5 console equivalence has not been measured. Labels live until the port closes, and reopening creates a new array. Error precedence follows the reference for null output and the existing open-port policy for handles. Exact scanout release timing, repeated same-buffer flips and concurrent guest label stores remain unverified. EOP-flip registration and interrupt tokens remain unimplemented; exposing these labels does not implement that separate API.
 - [GPU flips](../../../core/libs/prx/libSceVideoOut/src/VideoOutDriver.cpp) (libSceVideoOut) - a command-buffer flip of a buffer index with no registered buffer when the GPU reaches it presents black and completes like any flip (flip event, count, `flipPendingNum`). The console's behaviour is unknown; PPSA05684 requires that it completes: its renderer submits a flip of buffer 0 while another thread waits for `sceVideoOutIsFlipPending` to reach 0 before registering the buffers, and `flipPendingNum` counts that flip from its submission as in shadPS4
 - [sceVideoOutAddPreVblankStartEvent](../../../core/libs/prx/libSceVideoOut/src/Event.cpp) (libSceVideoOut) - how long before the vblank the console signals pre-vblank start is unknown. The event is triggered on each emulated vblank tick immediately before the vblank event, with its own count as the event data
+- [sceVideoOutRegisterBuffers, sceVideoOutGetFlipStatus, sceVideoOutGetVblankStatus](../../../core/libs/prx/libSceVideoOut/src/Buffer.cpp) (libSceVideoOut) - PS4 callers. A handle is treated as PS4 once buffers are registered through the PS4 `sceVideoOutRegisterBuffers`; from then on its flip and vblank status are written in the PS4 64- and 32-byte layouts, with `tsc` and `submitTsc` 0. A PS4 title that reads a status before it registers buffers gets the larger PS5 layout. The PS4 function accepts only linear A8R8G8B8_SRGB (0x80000000) and A8B8G8R8_SRGB (0x80002200) buffers without options; tiled PS4 buffers throw, as their layout differs from the PS5 tiling. Linear PS4 buffers may be 4 KiB aligned: the OpenOrbis graphics sample registers its second 1920x1080 buffer 8,294,400 bytes after the first. The PS4 alignment rule is not known

Subject: [PATCH 0113/1000] fix(libkernel): export _readv, _writev, _fcntl,
 _fstat, __sys_socketex

OpenOrbis programs and modules import these PS4 libkernel names (the
graphics, library and networking samples). The underscore names
forward to readv, writev, fcntl and fstat, as _ioctl already does;
_fcntl passes its argument on as a full 64-bit value, so the record
lock commands keep their whole pointer. __sys_socketex creates a
socket like socket(); its name argument is ignored, as sceNetSocket
does.

Subject: [PATCH 0114/1000] fix(relinker): stop module syscall scans at the PLT
 and skip the PS4 loader path

OpenOrbis modules keep read-only data after their code, as executables
do. The syscall scan of sce_module modules decoded it, and the module of
the OpenOrbis library sample (libExample.prx) failed with "Forbidden
syscall instruction". For modules with a PT_SCE_DYNLIBDATA segment, the
scan now stops at the end of the PLT after the last unwind function,
found by FindSceCodeEnd as for executables.

The same modules begin their executable segment with the
/libexec/ld-elf.so.1 string but have no PT_INTERP header, so code
analysis decoded the string and failed with "Unsupported Windows guest
TLS instruction (bytes: 64 2d 65 6c 66 2e)", which is the text "d-elf.".
When no PT_INTERP header covers the start of a PS4 code segment, code
analysis now starts after that exact string.

 - The length-changing path of the [instruction rewriter](../../../core/relinker/codegen/src/x86/X64InstructionRewriter.cpp) is not used by the [converter](../../../core/relinker/codegen/src/Amd64OnlyConverter.cpp): it does not adjust data-to-code references (relocations, FDEs, jump tables) or segment sizes, so every substitution keeps the instruction length.
 - A `PT_SCE_RELRO` segment that no `PT_LOAD` covers, the PS4 layout, is [loaded](../../../core/relinker/relinker/src/parsing/ElfReader.cpp) as a read-write `PT_LOAD` and stays writable after relocation; FreeBSD rtld makes `PT_GNU_RELRO` read-only once relocation is done, and what the console does with `PT_SCE_RELRO` is not checked.
 - In executables with a `PT_SCE_DYNLIBDATA` segment, the PS4 layout, the executable segment also holds read-only data after the code (CUSA00900: 37 MiB after its last function). The [relinker pipeline](../../../core/relinker/relinker/src/pipeline/RelinkerPipeline.cpp) therefore scans for syscalls and import call sites only up to the end of the PLT that follows the last function of the unwind table; code after the PLT without an unwind entry is not scanned. `--to-intel` and the `unused-filter=1` and `unused-filter=2` analyses are not limited this way.
-- In executables and guest modules with a `PT_SCE_DYNLIBDATA` segment, the [code analysis](../../../core/relinker/relinker/src/analysis/CodeInstructionCollector.cpp) of the Windows and macOS outputs follows code only from the end of `PT_INTERP` to the end of the PLT after the last function of the unwind table, the end the pipeline's scans above use; a guest module with PLT relocations and no PLT after its last unwind function fails as the executable does. Code after that PLT is not analyzed: a TLS access in it is not rewritten, an entry point or pointer into it is ignored, and a function symbol or init/fini array entry pointing into it fails the conversion.
+- The [syscall scan of `sce_module` modules](../../../core/relinker/relinker/src/guest/GuestModuleBuilder.cpp) with a `PT_SCE_DYNLIBDATA` segment stops at the same end of the PLT; code after it is not scanned.
+- In executables and guest modules with a `PT_SCE_DYNLIBDATA` segment, the [code analysis](../../../core/relinker/relinker/src/analysis/CodeInstructionCollector.cpp) of the Windows and macOS outputs follows code only from the end of `PT_INTERP`, or of the `/libexec/ld-elf.so.1` string that begins the segment when no `PT_INTERP` covers it, as in OpenOrbis modules, to the end of the PLT after the last function of the unwind table, the end the pipeline's scans above use; a guest module with PLT relocations and no PLT after its last unwind function fails as the executable does. Code after that PLT is not analyzed: a TLS access in it is not rewritten, an entry point or pointer into it is ignored, and a function symbol or init/fini array entry pointing into it fails the conversion.
 - A relocation against a dynamic symbol entry that is all zero, like the null symbol, takes the value 0 plus its addend, as the gABI defines for `STN_UNDEF` ([pipeline](../../../core/relinker/relinker/src/pipeline/RelinkerPipeline.cpp)). The Linux output imports such an entry as an unnamed weak symbol, which the host loader resolves to 0; the Windows and macOS outputs write the value into the slot ([relocation builder](../../../core/relinker/elfpatcher/src/windows/WindowsRelocationBuilder.cpp)). What the console's loader does with such an entry is not measured. OliSe Player (PPSA01153) has seven of them, and its code calls through those slots only when they are not 0 ([#4437](https://github.com/boykopovar/AnyPS5/issues/4437)).
 - The Linux placement of the `--to-intel` stubs in the [ELF patcher](../../../core/relinker/elfpatcher/src/linux/LinuxElfPatcher.cpp) is covered only by a synthetic test.
 - `--to-rosetta` lowers what Rosetta lacks on top of `--to-intel` ([matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp)). Rosetta runs AVX2, FMA, BMI1/2, F16C and MOVBE but reports none of them through CPUID, so code that checks CPUID takes its baseline path. RDSEED becomes RDRAND and CLWB a NOP. RDPID returns processor 0, because Rosetta's TSC_AUX is the constant 0xAAAAAAAB; the same value reaches RDTSCP's ECX, which is not converted. ADCX/ADOX fault under Rosetta and are not converted: compilers do not emit them, and code that checks CPUID sees no ADX. The conversions are covered by the converter tests; that the converted code runs under Rosetta was checked on an M5 Max only, outside this repository's CI.

Subject: [PATCH 0115/1000] docs: list the performance overlay with the
 diagnostics in USAGE

Its section moves from after HDR output to before Windows crash diagnostics, next to the other switches for looking into a run. Other open changes add their own sections right after HDR output.

 HDR output is available on Windows only. Titles see it when the monitor showing the window runs in HDR mode (Settings > Display > Use HDR), the window's Vulkan surface offers an HDR10 (`VK_COLOR_SPACE_HDR10_ST2084_EXT`) swapchain in a 10-bit format, the instance has `VK_EXT_swapchain_colorspace` and the device `VK_EXT_hdr_metadata`. The monitor's luminance comes from DXGI; a monitor that reports no peak luminance is taken as 1000 nits peak and full-frame, 0 nits black. On Linux and other hosts the output is always SDR, because the surface's formats do not show whether the display is in HDR. A title's BT.2100 PQ display buffers then reach the display unchanged; without HDR output they are converted to SDR.

The key can be moved with `TogglePerformanceOverlay` in the [input mapping](INPUT_MAPPING.md).

 ### Storing GPU results at each flip
 
 GPU results in storage images and render targets stay on the GPU until something reads their memory. A title that frees such an image after waiting for its GPU work and reuses the memory can have its new data overwritten when the results are stored later ([TechnicalDebt](../dev/TechnicalDebt.md)). `APS5_STORE_AT_FLIP=1` stores every pending result when a display buffer is flipped, at the cost of one write-back per pending image and frame. Any other value stops the title at its first flip.

Subject: [PATCH 0118/1000] fix(shader): translate f32 compares in f32 denormal
 modes 1 and 2

v_cmp_X_f32 and v_cmpx_X_f32 flush their denormal inputs by bit 0 of the
FLOAT_MODE f32 denormal field, as measured on RDNA2 (gfx1030): mode 1
keeps them and mode 2 flushes them. Both modes threw before.

 - [v_rcp, v_rsq, v_sqrt, v_log, v_exp, v_sin and v_cos](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (f32 and f16) use the driver's approximation for finite results, not the console's: the low bits can differ. Only NaN, invalid, zero and infinite results and the exact sin/cos zeros are chosen on the bits. Measured on RDNA2 (gfx1036) over every f16 input and 32,832 f32 inputs: RADV returns the hardware's bits for every input of rcp, rsq, sqrt and log and all but one of exp (f16 0x11c5, 1 ULP); NVIDIA (615.71.09) stays within 2 ULP except `v_log_f32` near 1.0 (next entry). [v_sin and v_cos](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) take the driver's sine or cosine of the radians of the exact cycle, except within 2^-12 of a turn from a zero of the function, where the result is the linear term of the exact distance to the zero: the hardware's constant 6.2831826 (0x40c90fd5) at the integers, which the hardware applies exactly to inputs below 2^-12 of a turn, and the f32 2π at the half and quarter turns, where the hardware is within 7 ULP of it. Outside those bands, a driver result more than 4 ULP from a Taylor series in turns of the exact cycle is replaced by the series, which is within 2 ULP of the true sine and cosine; the hardware is up to 9 ULP from them (gfx1035, 243,092 f32 inputs), so results stay within 13 ULP of the hardware on any driver. RADV returns the hardware's bits for every f16 input and for 32,422 sine and 32,486 cosine results of the 32,832 f32 inputs; the rest are 1 ULP off, except up to 14 ULP on either side of non-zero integers and up to 15 ULP beyond ±256 cycles, where the hardware's own reduction differs from the exact fraction, and up to 6 ULP inside the half- and quarter-turn bands. NVIDIA's own sine is within 1 ULP on 93% of the f32 inputs and up to 1,166 ULP off just outside the bands, its cosine within 163 ULP; the series replaces those results. A denormal f32 input with f32 denormals kept gives the hardware the input times 6.2831826; both hosts flush it.
 - [v_log_f32 and v_log_f16](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) keep the driver's log2 unless, for inputs within 1/8 of 1.0, it is more than 4 ULP from an eight-term series in x - 1, which then replaces it. `v_log_f16` goes through the same f32 lowering and is rounded to half. The series is evaluated for every `v_log` and chosen with `OpSelect` rather than a branch, so its seven fused multiply-adds and two multiplies are an unconditional cost. Measured on RDNA2 over all 3,145,728 f32 inputs within 1/8 of 1.0 (gfx1035, IEEE 0, f32 denormals flushed), the hardware is within 1 ULP of the correctly rounded log2 and the series within 2 ULP of it and within 3 ULP of the hardware (2 except at 0x3f752e47, 0x3f7baab0 and 0x3f7bc4fb), so a kept driver value is within 7 ULP of the hardware and a driver that returns the hardware's bits never triggers the gate; RADV (Mesa 26.2.4) returns the hardware's bits on the 9,280 such inputs measured on gfx1036; NVIDIA (615.71.09) was up to 23,947,836 ULP off at 1 - 2^-24 and is within 6 ULP inside the band after the change; outside it its own log2 stays up to 9 ULP off (measured up to 1.375). Over every f16 input, the change moves one `v_log_f16` result on NVIDIA (0x3bed, 1 ULP, onto the hardware's bits) and none on RADV.
 - [Ordered not-equal, less-than and greater-than compares](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) (shader recompiler) - `FPOrdNotEqual32` is emitted as `OpFUnordNotEqual`, and `FPOrdLessThan32` and `FPOrdGreaterThan32` as their ordered forms, each with both operands checked for NaN on their bits; the results are the same for every input. The AMD Windows driver 32.0.13058.8001 (Radeon 860M, RDNA 3.5) returns 1 for a NaN operand when any float form of not-equal feeds a ballot on a 32-wide subgroup (#825), and so does a less-than or greater-than against an infinity the driver sees as a constant (#3536), presumably rewritten into a not-equal by its compiler
+- [f32 compares in denormal modes 1 and 2](../../../core/shader/recompiler/Translation/src/VectorInstructions.cpp) (`v_cmp_X_f32` and `v_cmpx_X_f32` with X = eq, ge, gt, le, lg, lt, neq, nge, ngt, nle, nlg, nlt) flush their f32 denormal inputs by bit 0 of the `FLOAT_MODE` f32 denormal field: mode 1 keeps them as mode 3 does, and mode 2 flushes them as mode 0 does. Measured on RDNA2 (gfx1030, Radeon RX 6800, AMD Windows driver 32.0.21045.5002 through HIP) over 484 operand pairs of zeros, denormals, minimum normals, ones, the largest finite value, infinities and quiet and signaling NaNs of both signs, in VOPC form, at IEEE=0 and IEEE=1 with each f32 denormal mode 0 to 3, f32 round to nearest even, DX10_CLAMP=1, f16 denormals kept, f16 round to nearest even and FP16_OVFL=0. The PS5's gfx1013 is not measured.
 - [DB_SHADER_CONTROL.PRIMITIVE_ORDERED_PIXEL_SHADER](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - the host pixel interlock spans the whole shader, not only up to `s_sendmsg` ORDERED_PS_DONE.
 - [POPS collision SGPRs](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - the collision wave ID and intrawave collision mask read 0, so a title skips its POPS wait and runs its per-collision loop once.
 - [Image loads](../../../core/shader/recompiler/Optimization/src/ResourceTracker.cpp) (shader recompiler) - an image_load reads a sampled binding, also of an image the shader stores to, so in a primitive-ordered pixel shader it misses an earlier overlapping primitive's image_store in the same draw.

Subject: [PATCH 0119/1000] fix(shader): translate v_ldexp_f32 in f32 denormal
 modes 1 and 2

Mode 1 keeps subnormal inputs and flushes a result below 2^-126 to a
zero of its sign; mode 2 flushes subnormal inputs and rounds a subnormal
result in the f32 round mode, as measured on RDNA2 (gfx1030) in every
f32 round mode at IEEE=0 and IEEE=1. Both modes threw before.

 - [Packed f16 NaN results](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (`v_pk_add/mul/fma/min/max_f16`) follow the hardware measured on RDNA2 (gfx1035) at IEEE=0 and IEEE=1 with f16 round-to-nearest-even and f16 denormals kept: with IEEE=1 a signaling NaN input is quieted and min/max return the other operand only for a quiet NaN; with IEEE=0 NaN inputs pass through unquieted and min/max ignore signaling. In `v_pk_fma_f16` an invalid product (inf * 0) gives the default NaN even when src2 is a NaN. A shader without a known float mode is translated as IEEE=0, the mode titles use; a mode with another f16 rounding or that flushes f16 denormals throws.
 - [f32 denormals](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follow the shader's `FLOAT_MODE` f32 denormal field (bits 5:4) when it flushes them (0, and shaders without a known float mode, as in the 0xc0 most titles use), measured on RDNA2 (gfx1035) over 1444 rows per instruction at IEEE=0 and IEEE=1. `v_add/sub/subrev/mul/mul_legacy/mullit/fma/fmac/fmamk/fmaak/min/max/min3/max3/med3/fract/floor/ceil/frexp_mant/sin/cos_f32` flush their f32 inputs and their result to a zero of the same sign (`v_mullit_f32` measured on RDNA2 (gfx1036) over 6907 rows per mode at IEEE=0 and IEEE=1, so a positive denormal src2 counts as zero); the f32 compares, `v_cvt_i32/u32/rpi_i32/flr_i32_f32`, `v_frexp_exp_i32_f32`, `v_cvt_f64_f32`, `v_cvt_f16_f32`, `v_cvt_pkrtz_f16_f32`, `v_cvt_pknorm_i16/u16_f32` and `v_cvt_pk_u8_f32` flush their f32 inputs. `v_div_scale_f32` flushes all three inputs to signed zeros, measured on RDNA2 (gfx1036) over 2744 operand triples per mode at IEEE=0 and IEEE=1 with f32 denormals flushed and kept; its scale-down behaviour and host denormal preservation remain incomplete. `v_div_fixup_f32` flushes its src1 and src2 and keeps a denormal src0 and result, measured on RDNA2 (gfx1036) over 6859 rows per mode at IEEE=0 and IEEE=1. Tininess is detected after rounding, measured on RDNA2 (gfx1036) for `v_mul_f32` and `v_mullit_f32` at IEEE=0 and IEEE=1: a product is flushed when its value rounded to 24 bits with an unbounded exponent is below 2^-126, so `0x3f7ffffe * 0x00800001` (2^-126 * (1 - 2^-46)) gives `0x00800000` and `0x3f7fffff * 0x00800000` (2^-126 * (1 - 2^-24)) gives zero. The check rounds in the f32 round mode of `FLOAT_MODE` (bits 1:0), measured in all four modes, while the products themselves are still rounded to nearest even. This applies to `v_mul_f32`, `v_mul_legacy_f32`, `v_mullit_f32`, and to `v_fma_f32`, `v_fmac_f32`, `v_fmamk_f32`, `v_fmaak_f32` and `v_fma_mix_f32` when the addend is zero; with a nonzero addend the fused result is kept, so an exact result just below 2^-126 that rounds to it is not flushed. In the three directed modes the check is computed exactly from the significands. To nearest even (0, the mode of shaders without a known float mode) one factor is multiplied by 2^64, which is exact below 2^64, and the product with the other factor is compared with 2^-62. That multiply is a plain `OpFMul` like the product, and no f32 rounding mode is requested in the SPIR-V, so the check relies on the driver rounding f32 to nearest even by default, as the products do, and a product that rounds up to 2^-126 is the emitted product. `v_fma_mix_f32` follows this rule with mixed f16/f32 sources too, measured on RDNA2 (gfx1036) with f16 in either multiplicand slot, low and high half selection, and an f32 or f16 zero addend: f32 `0x00801002` times f16 `0x3bff` gives `0x00800000` to nearest at IEEE=0 and IEEE=1, while the neighbours `0x00801001` and `0x00801003` give zero and `0x00800001`. The tiny-product boundary was also measured for both signs in all four f32 round modes at IEEE=0; f16 inputs retain their previous conversion and denormal handling. `v_fma_mixlo_f16` and `v_fma_mixhi_f16` flush their f32 sources too and keep a product below 2^-126, measured on RDNA2 (gfx1036). `v_mad_legacy_f32` and `v_mac_legacy_f32` flush their inputs, their product and their result in every mode, see its entry; their product is still checked for tininess on its exact value, so one below 2^-126 gives zero even when it rounds to 2^-126, as the console's separately rounded encoding is not measured at this boundary. Denormal modes 1 and 2 throw for the other instructions. Not covered, and not measurable on RDNA2 (no such opcodes) or not measured: `v_mac_f32`, `v_mad_f32`, `v_madak_f32` and `v_madmk_f32` (rounded separately), `v_dot2_f32_f16` and `v_div_fmas_f32` (on hardware `v_div_fmas_f32` flushes only its result), f32 interpolation and `ds_add_f32` keep the previous lowering; `ds_min/max/cmpst_f32` flush both operands by the field, see the LDS float atomics entry. With f32 denormals kept (3) the results depend on the driver's default denormal behaviour, as no `DenormPreserve` execution mode is requested; `v_ldexp_f32` and the f32 compares are the exceptions. `v_cmp_X_f32` and `v_cmpx_X_f32` compare the operands as sign-magnitude integers with the NaN cases handled apart, so a denormal is not read as zero, measured on RDNA2 (gfx1036) over 256 operand pairs per opcode at IEEE=0 and IEEE=1 with f32 denormals kept and flushed. `v_ldexp_f32` preserves subnormal inputs and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, measured on RDNA2 (gfx1036) over 2163 rows in each of the four round modes at IEEE=0 and IEEE=1. An overflow rounds like any other result (infinity, or the largest finite value when the mode rounds that sign toward zero). With f32 denormals flushed it flushes a subnormal input and result, measured over the same rows in each round mode at IEEE=0 only. A device whose driver splits `Fma` into a multiply and an add flushes a product below 2^-126 before adding a non-zero addend in `v_fma_f32` and `v_fmac_f32`: `0x1fffffff * 0x1fffffff + 0x00800000` gives `0x00800000` instead of the fused `0x00ffffff` on RADV RENOIR (Mesa 26.2.4), whose compiled shader has `v_mad_f32` and no `v_fma_f32`. [F32DenormalFlush](../../../core/libs/prx/libSceAgcDriver/tests/execution/F32DenormalFlush.cpp) accepts that sum on such a device.
 - [v_rcp, v_rsq, v_sqrt, v_log, v_exp, v_sin and v_cos](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (f32 and f16) use the driver's approximation for finite results, not the console's: the low bits can differ. Only NaN, invalid, zero and infinite results and the exact sin/cos zeros are chosen on the bits. Measured on RDNA2 (gfx1036) over every f16 input and 32,832 f32 inputs: RADV returns the hardware's bits for every input of rcp, rsq, sqrt and log and all but one of exp (f16 0x11c5, 1 ULP); NVIDIA (615.71.09) stays within 2 ULP except `v_log_f32` near 1.0 (next entry). [v_sin and v_cos](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) take the driver's sine or cosine of the radians of the exact cycle, except within 2^-12 of a turn from a zero of the function, where the result is the linear term of the exact distance to the zero: the hardware's constant 6.2831826 (0x40c90fd5) at the integers, which the hardware applies exactly to inputs below 2^-12 of a turn, and the f32 2π at the half and quarter turns, where the hardware is within 7 ULP of it. Outside those bands, a driver result more than 4 ULP from a Taylor series in turns of the exact cycle is replaced by the series, which is within 2 ULP of the true sine and cosine; the hardware is up to 9 ULP from them (gfx1035, 243,092 f32 inputs), so results stay within 13 ULP of the hardware on any driver. RADV returns the hardware's bits for every f16 input and for 32,422 sine and 32,486 cosine results of the 32,832 f32 inputs; the rest are 1 ULP off, except up to 14 ULP on either side of non-zero integers and up to 15 ULP beyond ±256 cycles, where the hardware's own reduction differs from the exact fraction, and up to 6 ULP inside the half- and quarter-turn bands. NVIDIA's own sine is within 1 ULP on 93% of the f32 inputs and up to 1,166 ULP off just outside the bands, its cosine within 163 ULP; the series replaces those results. A denormal f32 input with f32 denormals kept gives the hardware the input times 6.2831826; both hosts flush it.
+- [v_ldexp_f32 in denormal modes 1 and 2](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follows the `FLOAT_MODE` f32 denormal field: mode 1 keeps a subnormal input and flushes a result below 2^-126 to a zero of its sign in every f32 round mode, also one that rounds to 2^-126 at subnormal precision (`0x3fffffff` scaled by 2^-127); mode 2 flushes a subnormal input to a zero of its sign and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, as mode 3 does. Measured on RDNA2 (gfx1030, Radeon RX 6800, AMD Windows driver 32.0.21045.5002 through HIP) over 10,260 rows (54 inputs of both signs: zeros, subnormals, normals near 2^-126 and 1.0, the largest finite value, infinities and NaNs, each scaled by 190 exponents from -2^31 to 2^31-1) at IEEE=0 and IEEE=1 with each f32 denormal mode 0 to 3 and f32 round mode 0 to 3, DX10_CLAMP=1, f16 denormals kept, f16 round to nearest even and FP16_OVFL=0; with the `clamp` modifier the result is clamped as in the other modes. The PS5's gfx1013 is not measured.
 - [v_log_f32 and v_log_f16](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) keep the driver's log2 unless, for inputs within 1/8 of 1.0, it is more than 4 ULP from an eight-term series in x - 1, which then replaces it. `v_log_f16` goes through the same f32 lowering and is rounded to half. The series is evaluated for every `v_log` and chosen with `OpSelect` rather than a branch, so its seven fused multiply-adds and two multiplies are an unconditional cost. Measured on RDNA2 over all 3,145,728 f32 inputs within 1/8 of 1.0 (gfx1035, IEEE 0, f32 denormals flushed), the hardware is within 1 ULP of the correctly rounded log2 and the series within 2 ULP of it and within 3 ULP of the hardware (2 except at 0x3f752e47, 0x3f7baab0 and 0x3f7bc4fb), so a kept driver value is within 7 ULP of the hardware and a driver that returns the hardware's bits never triggers the gate; RADV (Mesa 26.2.4) returns the hardware's bits on the 9,280 such inputs measured on gfx1036; NVIDIA (615.71.09) was up to 23,947,836 ULP off at 1 - 2^-24 and is within 6 ULP inside the band after the change; outside it its own log2 stays up to 9 ULP off (measured up to 1.375). Over every f16 input, the change moves one `v_log_f16` result on NVIDIA (0x3bed, 1 ULP, onto the hardware's bits) and none on RADV.
 - [Ordered not-equal, less-than and greater-than compares](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) (shader recompiler) - `FPOrdNotEqual32` is emitted as `OpFUnordNotEqual`, and `FPOrdLessThan32` and `FPOrdGreaterThan32` as their ordered forms, each with both operands checked for NaN on their bits; the results are the same for every input. The AMD Windows driver 32.0.13058.8001 (Radeon 860M, RDNA 3.5) returns 1 for a NaN operand when any float form of not-equal feeds a ballot on a 32-wide subgroup (#825), and so does a less-than or greater-than against an infinity the driver sees as a constant (#3536), presumably rewritten into a not-equal by its compiler
 - [DB_SHADER_CONTROL.PRIMITIVE_ORDERED_PIXEL_SHADER](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - the host pixel interlock spans the whole shader, not only up to `s_sendmsg` ORDERED_PS_DONE.

Subject: [PATCH 0120/1000] feat(libSceFont): implement
 sceFontCharactersRefersTextCodes and text code stepping

sceFontCharactersRefersTextCodes fills a 64-byte FontTextCodes with the
order and code of a text character and keeps the current, start and
term characters at +0x28, +0x30 and +0x38. The traversal follows the
PS4 11.00 libSceFont.sprx disassembly posted in the review of #4050,
which implemented the same rules: Refers never compares the character
with the term and returns null for a clustered or synthetic character,
sceFontTextCodesStepNext returns null at the term after visiting it,
sceFontTextCodesStepBack returns null at the start character, and both
steps skip synthetic characters. Null from StepNext at the end of the
chain and from StepBack at the head of the chain is assumed and not
covered by the report.

The signatures follow Orbital's IDA type database and SharpProspero. A
null cursor or output returns null as in KytyPS5; a null text character
throws. guest_font_tests gets configure_windows_unwind so the expected
exception reaches the test on Windows.

 - [sceFontWritingRefersRenderStepCharacter](../../../core/libs/prx/libSceFont/src/Text.cpp) (libSceFont) - the second argument is an out pointer to the writing's letter step, as in [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/d2413fc2ebd91d1b7234197c2dd5bd48e1cb6a51/src/libs/libFont.cpp#L1882-L1896) and the [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/Font/SceFont.Engine.cs) bindings. Measured on PS4 firmware 11.00 `libSceFont.sprx` (not on a PS5): exactly 8 bytes are written, the address of a step stored inside the writing, and a null writing writes null; shadPS4 and prosper treat the argument as a struct, which the measurement contradicts. The letter step lives in the writing, so the pointer stays valid as long as the writing does, and its contents are rebuilt by each call of this function. On the PS4 library repeated calls on one step walk the characters it covers and then return null; here every call returns the step's one character, so the second call differs. Assumed: each step covers one character and one glyph. PPSA06699 (Hot Shots Golf 2) dereferences the returned pointer for its character counts.
 - [sceFontWritingLineGetOrderingSpace](../../../core/libs/prx/libSceFont/src/WritingLine.cpp) (libSceFont) - the four outputs are written in the order the PS4 11.00 `libSceFont.sprx` writes them (line advance, leading space, space between spaced runs, trailing space); the parameter names in the [Orbital](https://github.com/AlexAltea/orbital/blob/master/tools/ida/db_types.json) IDA type database and the [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/Font/SceFont.Engine.cs) bindings order them differently (head, inline, tail, advance), and the PS5 library was not measured. PPSA01325's only call uses them in the PS4 order: it computes first - second - fourth - 0.25 * third and compares that, divided by a scale, with its width limit. The PS4 library writes the trailing space through its pointer without a null check whenever the leading-space pointer is set; that call throws here
 - [sceFontCharacterGetSyllableStringState](../../../core/libs/prx/libSceFont/src/Text.cpp) (libSceFont) - the signature `(textCharacter, int* syllableStringState)` follows [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/Font/SceFont.Engine.cs). Measured on PS4 firmware 11.00 `libSceFont.sprx` (not on a PS5): the state is 0 for Latin, CJK, Hangul, Arabic, Hebrew, Devanagari and the other scripts tried, and the library sets 1, 3 or 4 (never 2 on real text) for Thai while it creates the string; a null character or a null result returns `SCE_FONT_ERROR_INVALID_PARAMETER`, and a null character writes 0 to a non-null result. This returns 0 for every character outside the Thai block (U+0E00 to U+0E7F), as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/d2413fc2ebd91d1b7234197c2dd5bd48e1cb6a51/src/libs/libFont.cpp#L1805-L1815) does, and throws for Thai characters, whose cluster states are not modelled. SharpProspero's `SceFontSyllableString` names 0 NonDetection, 1 Starting, 2 Following, 3 Depending and 4 Connecting. PPSA06699 (Hot Shots Golf 2) calls it.
+- [sceFontCharactersRefersTextCodes, sceFontTextCodesStepNext and sceFontTextCodesStepBack](../../../core/libs/prx/libSceFont/src/Text.cpp) (libSceFont) - the signatures follow the [Orbital](https://github.com/AlexAltea/orbital/blob/cc408367da6a6ebbf5ac1ac559fefeadc73b2831/tools/ida/db_types.json#L679) IDA type database and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Font/SceFont.Engine.cs#L395-L406), and the 64-byte `FontTextCodes` with the order pointer at 0 and the code at 8 follows SharpProspero's [SceFontTextCodes](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Font/SceFontStructs.cs#L216-L228). The traversal follows the PS4 11.00 `libSceFont.sprx` disassembly posted in [#4050](https://github.com/boykopovar/AnyPS5/pull/4050#issuecomment-6114504202), not a PS5 measurement: the cursor keeps the current, start and term characters at +0x28, +0x30 and +0x38; `Refers` never compares the character with the term and returns null for a clustered or synthetic character; `StepNext` returns null at the term after visiting it; `StepBack` returns null when the current character is the start; both steps skip synthetic characters. Assumed and not covered by the report, which says `StepNext` returns null only at the term: `StepNext` also returns null at the end of the chain (for example with a null term), and `StepBack` at the head of the chain. A null cursor or output returns null as in [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/d2413fc2ebd91d1b7234197c2dd5bd48e1cb6a51/src/libs/libFont.cpp#L1696-L1740); a null text character throws, as its console result is unknown

Subject: [PATCH 0121/1000] feat(libSceAppContent): implement
 sceAppContentGetAddcontDownloadProgress

The signature (uint32_t service label, const NpUnifiedEntitlementLabel*,
progress*) follows SharpProspero Interop/AppContent/AppContent.cs.
dlc_emu dlc_content.cpp (fcf69b16) answers PARAMETER for a null label or
progress and NOT_FOUND for a label that is not installed additional
content. No additional content is ever installed here, as
sceAppContentAddcontMount, sceAppContentAddcontEnqueueDownload and
sceAppContentAddcontDelete already model, so every other call answers
NOT_FOUND and the progress, whose 16-byte layout SharpProspero gives,
is never written.

 - [sceAppContentDownloadDataFormat](../../../core/libs/prx/libSceAppContent/Export.cpp) (libSceAppContent) - empties the `/download0` directory, creating it if needed. Imported by PPSA01317. A null mount point returns `PARAMETER` as `sceAppContentTemporaryDataFormat` does, and another mount point throws as in `sceAppContentDownloadDataGetAvailableSpaceKb`; the console's error codes for both and its behaviour with files still open are unverified

 - [Temporary app-content storage](../../../core/libs/prx/libSceAppContent/Export.cpp) tracks one `/temp0` mount, preserves its files on unmount, and rejects new path resolutions until remount. Mount, format, space-query and unmount errors follow [fpPS4](https://github.com/red-prig/fpPS4/blob/04cefd43e6fddd1ab033e7980cd356d14c964905/sys/sys_path.pas); the pointer ABI is also declared by [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/AppContent/AppContent.cs). Existing open host descriptors remain usable after unmount; console behaviour with open files is unverified. Host filesystem failures still throw.

Subject: [PATCH 0123/1000] fix(libSceFiber): run a fiber on its own context
 when the context is large

Since 794714983 every fiber ran on an mmap'd host stack so that host calls
cannot overrun the small contexts PPSA01341 packs next to each other. A
title that derives state from the stack pointer then reads the wrong
memory: PPSA05684's job fibers have 512 KiB contexts at 1 MiB-aligned
addresses and find their job record by masking rsp with ~0xfffff, so the
job system lost track of a GameInit job and the game waited forever
right after loading big4r/actor76.txt. Its 64 KiB fibers fault later on
a host stack too.

A fiber now gets a host stack only when its context is smaller than
64 KiB; a larger context is the stack again, as on the console. The
limit sits between the 16 KiB contexts that need protection and the
64 KiB ones that need the guest stack (technical debt entry). The fiber
test runs a 512 KiB fiber and checks that its stack is in its context;
it fails without this change.

 ### Unknown function info
 
 - [_sceFiberGetThreadFramePointerAddress](../../../core/libs/prx/libSceFiber/Export.cpp) (libSceFiber, NID `0dy4JtMUcMQ`) forwards to `sceFiberGetThreadFramePointerAddress`; that the argument list matches is inferred from the export without the underscore, as for the underscore Ult exports, not measured
+- [Fiber stacks](../../../core/libs/prx/libSceFiber/Export.cpp) (libSceFiber) - a fiber whose context is smaller than 64 KiB runs on an mmap'd host stack of its context size plus 1 MiB, so host calls made from it (21 KiB deep when PPSA01341 reaches SPIRV-Tools from a 16 KiB context) do not overwrite the contexts packed next to it; a larger context is the stack, as on the console. PPSA05684 needs the second: its job fibers have 64 KiB and 512 KiB contexts, the 512 KiB ones at 1 MiB-aligned addresses, and find their job record by masking the stack pointer (`~0xfffff` for the 512 KiB ones), which a host stack breaks (the game waits forever in GameInit, or faults later in a 64 KiB fiber). The 64 KiB limit is chosen between these two titles, not measured: a title with small contexts that also derives state from the stack pointer, or one whose host calls exceed what is left of a large context, is not covered

Subject: [PATCH 0124/1000] fix(agc): write nothing for an empty register list

sceAgcCbSetShRegistersDirect and the other register list writers threw on
a count of 0 although the matching size functions report 0 words for it.
PPSA05684 calls the writer with an empty list at its main menu and
terminated. An empty list now writes no packet and returns the cursor,
as its size says; a null buffer still throws.

Subject: [PATCH 0125/1000] fix(agc): show the last frame's numbers in the
 performance overlay below 1 fps

Below 1 fps no one-second window holds two presents, so the overlay
showed FPS: 0.0, GPU: 0.0 MS and DRIVER: 0.0 MS, which is the common
case for titles that run slowly today. When the last second holds fewer
than two presents, FPS is now the last frame's rate, 1000 divided by its
time in ms, and GPU and DRIVER are that frame's growth of each total.
With two or more presents in the last second the numbers are the last
second's as before, so the two modes meet at 1 fps.

FPS below 1 is shown with two decimals: a frame every 2 s reads 0.50 and
one every 12 s reads 0.08. Times keep their format and their 9999 cap,
which USAGE.md now states for frames of 10 s or more. Nothing changes
while the overlay is hidden.

 - [fstat on a guest socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) fills the fields FreeBSD 11's soo_stat and pru_sense_null fill and zeroes the rest: S_IFSOCK, the read bits while the receive side is open or data is queued, the write bits while the send side is open, st_size and st_blksize. Only this process's shutdown closes a side here; a peer's shutdown, close or reset does not clear the bits as FreeBSD's socantrcvmore and socantsendmore do. st_size is the host's FIONREAD, which for a Linux datagram socket is the size of the next datagram where FreeBSD counts every queued byte, and st_blksize is the host's SO_SNDBUF, which Linux reports as twice the size that was set. A socketpair end reports st_dev and st_ino 0, where FreeBSD's uipc_sense reports NODEV and a per-socket number
 - [poll](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) waits on guest sockets and pipes, through `WSAPoll` on Windows and `poll` on Linux; the `pollfd` layout and flag values are FreeBSD's. A libSceNet socket joins the same host wait through the native socket libSceNet lends to libkernel. `WSAPoll` rejects `POLLPRI`, so on Windows a socket's `POLLPRI` is asked as `POLLRDBAND` and `POLLIN` as `POLLRDNORM`; Winsock reports urgent data until it is read with `MSG_OOB`, where FreeBSD 11.4's `sopoll_generic` stops once the normal stream passes the mark. Guest `send` and `recv` refuse `MSG_OOB` with `EOPNOTSUPP`, so urgent data can only come from an outside peer and Windows keeps reporting `POLLPRI` after the stream passes the mark. A pipe follows FreeBSD's `pipe_poll`: the read end is readable when data is buffered, either end reports `POLLHUP` once the other end is closed, with the requested `POLLIN` and `POLLRDNORM` bits and without `POLLOUT`, which `pollscan` clears, and the write end is writable when `PIPE_BUF` (512) bytes are free on Windows, or when the host kernel says so on Linux. `POLLOUT` on a read end throws: FreeBSD opens both ends for reading and writing and reports it writable, and host pipes are one-way. Windows pipes cannot be waited on, so while a pipe is polled `poll` checks it with `NtQueryInformationFile` and waits on the sockets in slices of 1 ms. A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket nor a pipe (files, stdio) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on. A closed socket descriptor reports `POLLNVAL`; the console's limit on the descriptor count is unknown and not checked
 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
-- [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the send and receive timeouts and low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.

A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.
 - [connect to AF_UNSPEC](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) dissolves a datagram association as FreeBSD 11.4's `udp_disconnect()` does, which resets the local address to the wildcard address and keeps the port. On Linux a socket bound to an explicit port keeps its local address as well (`127.0.0.1:<port>` stays `127.0.0.1:<port>`), because a bound socket cannot be bound again; one bound to port 0 is bound again to the wildcard address with the port it had
 - [msync](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) follows FreeBSD 11's `kern_msync` and `vm_map_sync`, not measured on the console: the address is rounded down to the page, a range that wraps is `EINVAL`, as is `MS_ASYNC` with `MS_INVALIDATE`, and a range whose start or any page is not mapped (as `sceKernelVirtualQuery` reports it, reservations included) is `ENOMEM`; a page unmapped from inside a larger mapping still counts as mapped there, since `sceKernelVirtualQuery` keeps reporting the whole mapping. The guest has no file mappings, so a successful call writes nothing back. `MS_INVALIDATE` on a mapped range throws: FreeBSD returns `EBUSY` when the range holds `mlock`ed pages, and locked pages are not tracked
 - [madvise](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) accepts `MADV_PROTECT` (10) as a no-op hint without modifying process protection. FreeBSD 11's `kern_madvise` (`sys/vm/vm_mmap.c`) handles it before the address check, ignores the address and length, and calls `kern_procctl(..., PROC_SPROTECT, PPROT_SET)`, which requires `PRIV_VM_MADV_PROTECT` and fails with `EPERM` without it. Returning 0 unconditionally assumes the calling process is privileged. Console behaviour is unverified

Subject: [PATCH 0127/1000] perf(shader): intersect dominator sets as bitsets

Structurizing recomputes dominators after every CFG rewrite, and each block started from a vector of every block id. The same fixed point now runs on bitsets and still writes the sorted id lists.

Subject: [PATCH 0128/1000] feat(libc): export the fmin and fmax family

Adds fmin, fminf, fminl, fmax, fmaxf and fmaxl, the remaining
missing members of the C99 minimum/maximum family, with the NaN
propagation and signed-zero handling guest_fminf pins down (host
std::fmin does not guarantee the sign of a zero result). The
previous libSceLibcInternal copy of fminf is removed so the export
stays single-owner. PPSA28319 imports fmaxf from libc.prx; the
other five names were exported by nothing.

The app type and the block are not used. The endpoint calls assume the PS4 `libSceVoiceQoS` signatures (`CreateLocalEndpoint(int* id, user, device)`, `DeleteLocalEndpoint(id)`, `CreateRemoteEndpoint(int* id)`, `DeleteRemoteEndpoint(id)`, `Connect(int* id, local, remote)`, `Disconnect(connection)`, `SetLocalEndpointAttribute(id, attribute, value, size)`), not confirmed on a PS5 title. Endpoints and connections are tracked (an endpoint in a connection cannot be deleted, a pair connects once); local endpoint attributes are stored as given, as their ids and defaults are unknown; other endpoint and packet calls remain throwing stubs. The not-initialized error 0x804E0901 is assumed from the 0x804E09xx numbering, and unknown ids return `ARGUMENT_INVALID`.

Subject: [PATCH 0131/1000] test(relinker): run the file writer's replacement
 test on a copy of itself

The running-executable replacement test copied /bin/sleep under the
names "running" and "leftover" and started the copy. On Ubuntu 26.04
/bin/sleep is the uutils multi-call coreutils binary, which picks the
utility from the file name of the path it was started through, not
from argv[0], so the copy printed "coreutils: unknown program
'running'" and exited, and file_writer_binary and file_writer_text
failed without ever replacing a running executable. The test now
copies its own executable and starts it with a "wait" argument that
sleeps, so it no longer depends on how a system binary reads its name.

Subject: [PATCH 0132/1000] refactor(agc): make the largest device-local heap
 lookup public

LargestDeviceLocalHeap picks the heap that the texture cache budgets
read their VK_EXT_memory_budget numbers from. It moves out of the
anonymous namespace of ShaderResources.cpp so the performance overlay
can report the same heap.

 ### Functional
 
 - [sceKernelMprotect, sceKernelMtypeprotect](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) (libkernel) over a range with a gap that is not registered in the allocation tracker protect the registered parts and skip the gap, and return 0, as FreeBSD 11.4's [`vm_map_protect`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/vm/vm_map.c) does (it has no check for holes); a range whose start is unmapped (also when later pages are mapped) returns `SCE_KERNEL_ERROR_EINVAL` (`mprotect`: `EINVAL`) because an existing test pins that for an unmapped start; FreeBSD answers 0 there too (`vm_map_protect` takes the next entry), so this errno is not taken from the source and was not changed. `sceKernelMprotect` threw for a gap before, which ended the title. Every part is checked for a GPU or image pin before the first one is protected; the parts are then protected one after the other, so a host protection failure in a later part leaves the earlier parts changed (FreeBSD's `vm_map_protect` cannot fail in its second pass). The behaviour on the console is not known. None of this was measured on a console.
+- [sceKernelMprotect protection bits](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) (libkernel) - bits outside `0x3F7` are dropped instead of refused, as FreeBSD 11's [`sys_mprotect`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/vm/vm_mmap.c#L606) does with `VM_PROT_ALL`. Onimusha: Way of the Sword (PPSA27836 01.000.001) maps direct memory with `0xf2` and then protects it with `0xfffffff2`. Not measured on a console; the map calls and `sceKernelMtypeprotect` still refuse undefined bits
 - [JIT shared memory](../../../core/libs/prx/libkernel/DirectMemory/Jit.cpp) (libkernel) - `sceKernelJitCreateSharedMemory`, `sceKernelJitCreateAliasOfSharedMemory` and `sceKernelJitMapSharedMemory` take the signatures of [Orbital](https://github.com/AlexAltea/orbital)'s `tools/ida/db_types.json` (name, length, maximum protection, descriptor out; descriptor, maximum protection, descriptor out; descriptor, protection, address in and out), which ps4sdk, ps5-jar-loader and the call sites in RetroArch PPSA99169, XPSemu PPSA97358 and VLC PPSA85300 match; SharpProspero declares the alias as returning the descriptor. The object is a host anonymous file shared by its descriptors (a `memfd` on Linux, a delete-on-close temporary file mapped as an executable section on Windows), the alias is a duplicate descriptor, and every map maps the whole object, so writes through one view show through the others; a non-null address is a hint, as in `mmap` without `MAP_FIXED`. Not measured on the console: a length that is zero or not a multiple of 16 KiB and protection bits other than CPU read, write and execute are `EINVAL`; an alias or a map asking for more than the descriptor's maximum protection (write and execute counting as read) is `EACCES`, as FreeBSD 11's `vm_map_protect` treats a protection past `max_protection`; a descriptor that is not a JIT object is `EBADF`. The name is ignored, the objects do not count against the flexible memory budget, `mprotect` of a view is not limited to the maximum protection, and `mmap` of the descriptors is unsupported, as for `shm_open`. On Linux the `memfd` is created without `MFD_EXEC`, which Linux 6.3 added and older kernels reject with `EINVAL`, and relies on the protection of the mapping: the flag only sets the file's execute permission bits, and the direct memory `memfd` is mapped executable the same way; a host with `vm.memfd_noexec` set to 2 refuses the creation and the call throws
 - [kqueue and kevent](../../../core/libs/prx/libkernel/Equeue/src/Kqueue.cpp) (libkernel) follow FreeBSD 11's [`kern_event.c`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/kern_event.c) (`kqueue_kevent`, `kqueue_register`, `kqueue_scan`, the timer and user filters) over the event queue; nothing is measured on a console. The descriptor is a host null device registered as the kqueue: `close` and `sceKernelClose` close the queue and `dup`/`dup2` of it throw, but `read`, `write` and `fstat` act on the null device instead of failing with `EOPNOTSUPP` or reporting `S_IFIFO`. Read and write events are supported on guest sockets only, plus the timer, user and [vnode](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) filters; other filters, `EV_DISABLE`, `EV_DISPATCH`, `EV_FORCEONESHOT`, `NOTE_LOWAT`, `EV_CLEAR` on a socket, `EVFILT_READ` on another kqueue, a `NOTE_NSECONDS` period above one second with a fraction (11.0 converts the fraction with the microsecond macro), any change to an existing timer (11.0 keeps the armed expiry and applies the new period after it, 11.4's `filt_timertouch` restarts it) and a negative `nevents` throw. A new user event keeps its `fflags` unmasked and is not triggered by `NOTE_TRIGGER`, because `filt_userattach` reads the already cleared `kn_fflags`. The timer limit `kq_calloutmax` (`ENOMEM`) is not enforced, and closing a kqueue wakes a thread waiting on it in `kevent` with `EBADF`, where `kqueue_drain` makes the close wait for that thread. A level-triggered event is reported once per call and moved behind the other events, as in `kqueue_scan`; the `sceKernel*Equeue` calls keep their own collection loop
 - [EVFILT_VNODE, sceKernelAddFileEvent and sceKernelDeleteFileEvent](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) (libkernel) watch the host file or directory behind the descriptor and turn host changes into FreeBSD 11 vnode hints, which [`filt_vfsvnode`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L5032) adds whole when they share a bit with the requested `fflags`: a write that grows a file is `NOTE_WRITE | NOTE_EXTEND`, another write `NOTE_WRITE`, a shrinking truncate or an attribute change `NOTE_ATTRIB`, a higher link count `NOTE_LINK`, a lower one or a pending delete `NOTE_DELETE`, a new path `NOTE_RENAME`; in a directory, an entry created, removed or renamed is `NOTE_WRITE`, with `NOTE_LINK` for a subdirectory, and on Linux an entry moved from or to another directory adds `NOTE_EXTEND`; inotify queues the two halves of a rename one after the other, so a watcher woken by the first can read it alone, and a half read without the other is classified only after a `getdents64` on the watched directory, which takes the directory lock that `rename` holds until both halves are queued ([`do_renameat2`](https://github.com/torvalds/linux/blob/v6.8/fs/namei.c#L4975) around `vfs_rename` and its `fsnotify_move`, [`iterate_dir`](https://github.com/torvalds/linux/blob/v6.8/fs/readdir.c#L103)), an ordering taken from the kernel source, not from inotify(7), which promises none; a directory registered with `NOTE_EXTEND` on Windows is accepted, as `vfs_kqfilter` does not check it, but never receives it, because the directory handle cannot tell a move between directories from a removal plus an addition. FreeBSD's hints depend on the filesystem and the console's filesystems are not known: a growing `ftruncate` reports `NOTE_WRITE | NOTE_EXTEND` where `vop_setattr_post` reports `NOTE_ATTRIB`, and on Windows `utimes` on a file reports `NOTE_WRITE`. Windows uses `FindFirstChangeNotification` on the parent directory (and on a watched directory itself) and compares `GetFileInformationByHandleEx` snapshots at least every 50 ms, because a write through an open handle is reported only when the handle is flushed or closed, so file hints can arrive 50 ms late, and a file deleted while watched, which the POSIX delete of Windows 10 1903 moves into `$Extend\$Deleted` until its last handle closes, reports `NOTE_DELETE` without `NOTE_RENAME` and keeps its handle without a parent directory watch, as that directory cannot be watched; Linux uses inotify on the file and is not run. `NOTE_REVOKE`, `NOTE_OPEN`, `NOTE_CLOSE`, `NOTE_CLOSE_WRITE`, `NOTE_READ`, unknown bits and descriptors other than files, directories, pipes and sockets throw. `sceKernelAddFileEvent(eq, fd, watch, udata)` and `sceKernelDeleteFileEvent(eq, fd)` take the [OpenOrbis](https://github.com/OpenOrbis/OpenOrbis-PS4-Toolchain/blob/0a1aaf9d/include/orbis/libkernel.h#L35) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0/src/SharpProspero/Interop/Kernel/KernelEqueue.cs#L164) signatures; `watch` is taken as the `fflags` and the event is added with `EV_CLEAR`, neither confirmed on a title

Subject: [PATCH 0135/1000] fix(tools): write technical debt files with LF line
 endings

On Windows debt_split rewrote the index and the debt files with CRLF, and resolve staged them that way when core.autocrlf is off. The files are now written through open(..., newline="\n"), which also works on Python 3.9, where Path.write_text has no newline argument.

Subject: [PATCH 0136/1000] feat(agc): show draws, pipelines, memory and
 resolution in the performance overlay

The overlay gains five lines below the first ones, each shown only when
its data exists:

- DRAWS: draw and dispatch packets per frame over the last second. Each
  packet worker counts them in its own counter, one relaxed load, add
  and store per packet without a lock prefix, which the overlay sums
  once per shown frame.
- SHADERS: pipelines created in the last second and in total, counted
  where a graphics pipeline is built for a draw state the cache had not
  seen and where a compute pipeline is created for a dispatch shader.
- VRAM: usage and budget of the largest device-local heap from
  VK_EXT_memory_budget.
- RAM: the process's private memory, PrivateUsage on Windows and
  RssAnon plus VmSwap from /proc/self/status on Linux.
- RES: the display buffer's and the swapchain's size.

VRAM and RAM are read at most once a second, and only while the overlay
is shown; hidden, the only added work is the packet and pipeline
increments. The font gains B, C, H, K, L, O, T and W. With every line
the panel is 232 pixels tall at 1080p, a fifth of the window, so it
keeps one mode.

Subject: [PATCH 0137/1000] test(agc): cover the performance overlay's new
 lines

agc_performance_overlay_statistics checks the per-frame draw and
dispatch averages, the pipelines of the last second, the per-worker
packet counters across threads, the count and size formats, the order
and omission of the new lines, the RES fallback for long sizes, the
glyph bits of every line of the full panel and of the new letters, the
once-a-second sampling and that touching 64 MiB raises the private
memory. It also prints what a counted packet costs.

agc_performance_overlay draws the full panel at 1920x1080 on lavapipe
and compares every glyph pixel of every line, with nothing changed
outside the panel; reads VRAM through VK_EXT_memory_budget; checks that
a shown frame samples the memory and draws the VRAM, RAM and RES lines;
and keeps the hidden presentation bit-identical with the full panel.

 performance overlay below 1 fps

SHADERS counted the pipelines created between the first and the last present of the last second, so below 1 fps, with one present in that second, it read 0, as FPS did before. It now counts those created during the last frame there, like the other lines. The statistics test checks DRAWS, DISPATCH and SHADERS for a present alone in its second.

Subject: [PATCH 0140/1000] feat(agc): mark the performance overlay PROFILED
 while a profile switch is on

GPU and DRIVER need APS5_PROFILE_GPU or APS5_PROFILE_DRAW, and those switches add timestamp queries to every batch and timers to every packet, which changes the timings the panel shows. A screenshot of such a run could pass for an unprofiled one, so while either switch is on the panel now starts with a PROFILED line.

Subject: [PATCH 0141/1000] fix(agc): rasterize a multisampled target without
 MSAA_ENABLE at the pixel center

A draw with PA_SC_AA_CONFIG.MSAA_NUM_SAMPLES > 0 and
PA_SC_MODE_CNTL_0.MSAA_ENABLE clear threw. On GFX10 and later the bit
is what makes the rasterizer use the programmed sample locations; with
it clear the draw now keeps the target's sample count with every sample
at the pixel center. Points, lines, a depth target and
alpha-to-coverage still throw.

 - [GS_FAST_LAUNCH geometry](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - `VGT_SHADER_STAGES_EN.GS_FAST_LAUNCH = 1` with a point list and `GE_CNTL` groups of one vertex and one primitive decodes as one point per subgroup, with the primitive limit taken from `GE_NGG_SUBGRP_CNTL.PRIM_AMP_FACTOR` and the GS/ES VGPR counts not required. Follows how RADV drives mesh shaders on gfx10.3 (`ac_nir_lower_ngg.c`, the workgroup index comes from the vertex id of the first thread), not measured on the console. Fast launch 2, other group sizes or input primitives and indexed fast-launch draws still throw. PPSA03671's fast-launch draws decode, but the title stops earlier in a wave64 vertex program, so they have not reached the GPU yet.
 - [Alpha-to-coverage](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - only `DB_ALPHA_TO_MASK = 0xaa01` is accepted: the enable bit with the four quad offsets at 2 and no `OFFSET_ROUND`, the undithered setting [radeonsi](https://gitlab.freedesktop.org/mesa/mesa/-/blob/bffd91947efc1932da99aca69fc540d6d4201b0c/src/gallium/drivers/radeonsi/si_state.c#L371-L381) programs. Draws are single-sampled, so the pixel shader [writes](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) `SampleMask` 0 when its MRT0 alpha is below one half or NaN and all ones otherwise, and runs with late fragment tests. That rule was measured on a Radeon 660M (gfx1035, RADV with `RADV_DEBUG=noatocdithering`, which programs the same register) for 0, -0, 0.25, the two floats below one half, one half, the two above, 0.75, 1, 2, -1, both infinities and both NaNs, and is pinned in [AlphaToCoverage.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/AlphaToCoverage.cpp); it is not measured on gfx1013. Vulkan's `alphaToCoverageEnable` is not used: the NVIDIA driver 615.78.08 dithers single-sample coverage (an alpha of 0.25 writes half the pixels of an RTX 3050 Laptop target). Other offsets, `OFFSET_ROUND`, a sample-mask export, and an MRT0 that is missing, swizzled, packed or exported without a floating-point alpha throw. A draw without a color target on MRT0 keeps alpha-to-coverage from its MRT0 export, as [radeonsi exports MRT0 as `32_AR` for alpha-to-coverage without a color buffer](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-24.0.0/src/gallium/drivers/radeonsi/si_state_shaders.cpp#L2425-L2431). A draw that enables alpha-to-coverage with no MRT0 export still throws: what the console covers then is not measured. Default dithered `DB_ALPHA_TO_MASK = 0x18701` additionally uses a per-quad sample-mask table [measured on gfx1036](https://github.com/boykopovar/AnyPS5/pull/4451#issuecomment-6124848921) for eight standard samples with FP16_ABGR or 32_ABGR exports; other sample counts, custom locations, EQAA combinations and dithered UNORM16/SNORM16 exports throw. The dithered rule is not measured on gfx1013.
 - [MSAA_ENABLE on a single-sample target](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - `PA_SC_MODE_CNTL_0.MSAA_ENABLE` with `PA_SC_AA_CONFIG.MSAA_NUM_SAMPLES = 0` is drawn like the same state without the bit when sample 0 of the four `PA_SC_AA_SAMPLE_LOCS_PIXEL_*_0` registers is at the pixel center and the draw rasterizes filled triangles with alpha-to-coverage and conservative rasterization off. [RADV](https://gitlab.freedesktop.org/mesa/mesa/-/blob/745709a000482a4a24c91faef5c5a40bd653a863/src/amd/vulkan/radv_cmd_buffer.c#L13606-13609) programs this state for one-sample custom sample locations on GFX10 and later, where the bit makes the rasterizer use the programmed location of sample 0 ([061bc615](https://gitlab.freedesktop.org/mesa/mesa/-/commit/061bc6151a11597f720535f00e79a5752e24aff6)); that the bit changes nothing else for such a draw is inferred from that and is not measured on hardware. Other locations of sample 0, absent location registers, points, lines, rectangles, alpha-to-coverage and conservative rasterization throw
+- [A multisampled target rasterized without MSAA_ENABLE](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - `PA_SC_AA_CONFIG.MSAA_NUM_SAMPLES` > 0 with `PA_SC_MODE_CNTL_0.MSAA_ENABLE` clear is drawn with the target's sample count and every sample at the pixel center, as a single-sample scan into a multisampled target already is. On GFX10 and later the bit is what makes the rasterizer use the programmed sample locations ([RADV 061bc615](https://gitlab.freedesktop.org/mesa/mesa/-/commit/061bc6151a11597f720535f00e79a5752e24aff6)), and with multisampling disabled GL rasterizes at the pixel center and gives the fragment full coverage, which radeonsi programs by clearing the bit; that the hardware does the same with `MSAA_NUM_SAMPLES` > 0 is inferred from these and is not measured on hardware. Points, lines, a depth target and alpha-to-coverage throw. SONIC SUPERSTARS (PPSA06888) draws such a 2x target.
 - [sceAgcDriverGetEqContextId](../../../core/libs/prx/libSceAgcDriver/Eq/src/Query.cpp) (libSceAgcDriver) - returns `ident`: an end-of-pipe interrupt is delivered only to the registration whose id equals the raising queue, so `ident` is that context's id (titles register 0 or 1 for graphics and `0x20 + 8 * pipe + queue` for compute). The console's value is not known; KytyPS5 returns the event's `data`, which it fills with the interrupt's context id, whereas `data` here is the EV_CLEAR trigger count. Other event filters throw
 - [User data registers](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Diagnostics.cpp) (AGC driver) - a `SPI_SHADER_USER_DATA_*` or `COMPUTE_USER_DATA_*` register the title never wrote reads as 0 when a stage's RSRC2 count covers it, as Kyty (zeroed `UserSgprInfo`) and SharpEmu (missing registers read 0) do, and as AMD PAL and Mesa initialize them; the console's value is not confirmed
 - [SET_PREDICATION](../../../core/libs/prx/libSceAgcDriver/Execution/src/Pm4.cpp) (AGC driver) - boolean predication follows the AMD PM4 encoding [Mesa](https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/amd/common/sid.h) uses: operation 3 reads 64 bits and 4 reads 32 bits, and bit 8 runs predicated packets when the value is non-zero (clear: when it is zero); the bit 12 hint is ignored. The address must have its low 4 bits clear, as `sceAgcDcbSetPredication` writes it. Query predication (Z-pass, primitive count), a predicated COND_EXEC, predicated command buffer chains and flips in predicated command buffers throw

Subject: [PATCH 0144/1000] refactor(agc): count compute pipelines in the
 helper that creates them

The overlay's SHADERS count for compute pipelines sat in VulkanDevice::dispatch, inside a block that another open change moves. CreateComputePipeline now counts each pipeline it creates, so the count follows the creation wherever it runs. The capture replay path, which creates the same title pipelines, is counted too.

Subject: [PATCH 0146/1000] docs(progress): the README links the history page,
 not its chart

The README no longer embeds history.svg; it links history.html, which the progress page also links.

 ## History
 
-[`tools/progress_history.py`](../../tools/progress_history.py) measures the first-parent history of `main` with the same rules as `progress.py` and writes `history.json`, `history.svg` (shown in the README) and `history.html` (the chart with a tooltip per day plus a table, linked from the end of the progress page). The chart plots counts, not percentages: implemented and declared library functions and decoded shader instructions, so it shows how much is added over time; the percentages are on the progress map and the badges. It takes one point per day, at the last commit of the day, and skips commits whose tree lacks the scanned paths. The chart compacts as days accumulate: up to 31 days it labels every day, up to 150 days one label per Monday, beyond that one per month; points (and their tooltips) are drawn up to 45 days, after which the table and `history.json` keep every day. Old trees are measured with today's counting rules and instruction list, so the series is comparable but not what the page showed on that day. The workflow checks out the full history for it.

 - A pull request that conflicts with `main` and has no activity for 7 days is labeled `stale` with a reminder. It is not closed.
 - If a pull request needs another one first, say so on the checklist line (`Depends on: #N`; `none` otherwise).
 - If a pull request fixes a stop or a wrong result seen on a title, name it on the checklist line with the title ID and its [Game bring-up](https://github.com/boykopovar/AnyPS5/discussions/categories/game-bring-up) discussion (`Unblocks: PPSA01325 #3232`; `none` otherwise). Reviewers review these first.
+- For GPU changes, list each tested GPU's vendor, model, driver and OS on the checklist line. CI runs GPU tests only on lavapipe, so reviewers may ask for a run on another vendor before merging.
 - Fixes a title needs go to `main` as pull requests. A Game bring-up discussion lists the open pull requests and local changes the title still needs; update the list when one is merged, closed or replaced.
 - The PR overlap comment lists open pull requests that change the same lines or exports; agree with their authors which one goes first and declare it with `Depends on`.
 - Run the tests before opening the pull request and describe what was tested (OS, title or homebrew).

+- [sceAjmInstanceCreate](../../../core/libs/prx/libSceAjm.native/src/Ajm.cpp) (libSceAjm.native) - a full 14-bit instance slot namespace returns `0x80930007` (`OUT_OF_RESOURCES`), as [shadPS4's InstanceCreate](https://github.com/shadps4-emu/shadPS4/blob/15abf68c9b52c4b04d094f2837719fdb871021f3/src/core/libraries/ajm/ajm_context.cpp) does for its own instance pool (PS4). The 16384 slots per codec prefix are this runtime's existing ID layout, not a measured console capacity; the PS5 capacity and exhaustion result are unverified.
 - [sceAjmDecWVorbisCreateHeaderPacket, sceAjmDecWVorbisCreateSetupPacket](../../../core/libs/prx/libSceAjm.native/Export.cpp) (libSceAjmWVorbis, implemented in libSceAjm.native) - unknown signatures
 - [sceAjmBatchJobGetInfo](../../../core/libs/prx/libSceAjm.native/src/Ajm.cpp) (libSceAjm.native) - writes the result and format sideband of a run job without buffers with the `SIDEBAND_FORMAT` flag (0x400000000000), as [KytyPS5](https://github.com/KytyPS5/KytyPS5) does, not confirmed on a PS5 title; the format reports bitrate 0 for ATRAC9 as in KytyPS5, while [shadPS4](https://github.com/shadps4-emu/shadPS4) derives it from the superframe size; before the instance is initialized it returns the not-initialized result (1) and no format, like the other run jobs here, while KytyPS5 returns result 0 with the format of the uninitialized decoder
 - [sceAjmDecMp3ParseFrame](../../../core/libs/prx/libSceAjm.native/src/Ajm.cpp) (libSceAjm.native) - signature, result layout and rate tables taken from the [shadPS4](https://github.com/shadps4-emu/shadPS4) reimplementation of the PS4 library, not confirmed on a PS5 title: the layer field is not checked and MPEG-2.5 stops at 64 kbps; the original file length (`parse_ofl`) layout (Xing/Info + LAME tag, VBRI, Fraunhofer `0xB4` block with its CRC, encoder delay = samples per frame + LAME delay + 529) also comes from shadPS4 only, and the Fraunhofer block has no other public description

A title may declare a larger budget through `kernel.flexibleMemorySize` in `param.json`; this does not reduce the 13.5 GiB direct-memory size. Rejection of zero or a value not aligned to 16 KiB has not been measured on a console. This segment-accounting model follows [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/3a9f57265d28975658f1ca941daa5c879c7a74bd/src/core/module.cpp#L165), which maps every segment of a module outside its system module directory as flexible memory on the PS4. [Counted](../../../core/libs/prx/libkernel/Module/src/ModuleInfo.cpp) are the segments the title's ELF gives permissions, each rounded to 16 KiB pages; not counted are segments without permissions, the relinker's own blocks (on Linux both are the read/write/execute `PT_LOAD`s, plus the header block at file offset 0; on Windows everything outside the `.elf` sections) and the host system libraries. The Linux image carries no marker for the relinker's blocks, so they are told apart by those flags and that offset only: a title segment that is writable and executable, or starts at file offset 0, is not counted. A module whose segments exceed what is left still loads, and the available size then reads 0; shadPS4 fails the segment map instead ([memory.cpp](https://github.com/shadps4-emu/shadPS4/blob/3a9f57265d28975658f1ca941daa5c879c7a74bd/src/core/memory.cpp#L519-L524) returns `EINVAL`, [module.cpp](https://github.com/shadps4-emu/shadPS4/blob/3a9f57265d28975658f1ca941daa5c879c7a74bd/src/core/module.cpp#L168-L169) asserts). Which segments the PS5 charges, its rounding, whether system modules use the title's budget and when an unload releases the charge are not measured. PPSA15508 subtracts the reported size and a 10 MiB module allowance from its own 448 MiB budget at start-up and stops when the result exceeds its 146 MiB code and data limit ([#2883](https://github.com/boykopovar/AnyPS5/issues/2883))

Waiters share the queue of `sceKernelSyncOnAddressWait`. Operation 0 fails with `EOPNOTSUPP` and operations above 26 with `EINVAL`, as in FreeBSD 11; `UMTX_OP_WAIT_UINT` with a value that does not fit in 32 bits returns 0 at once, as FreeBSD's zero-extended compare does. Operation 1 throws, since PPSA12544's call_once uses it in a way FreeBSD rejects; the other operations throw, and so does a misaligned object. PPSA12544's `libc.prx` passes `UMTX_OP_WAIT` and `UMTX_OP_WAIT_UINT` a pointer to a 4-byte microsecond timeout with size argument 0, which FreeBSD reads as a `timespec`, and waits for a running call_once with operation 1; its `PS5Util.prx` passes a `timespec`. Whether the console reads a microsecond timeout there, and what operation 1 does on it, is unverified. A libc call cannot be told apart from a `timespec` call by the size argument alone, so a timeout with size argument 0 is read as a `timespec` and only throws when it is not a valid one (negative seconds, nanoseconds outside [0, 1e9)), which is where FreeBSD would return `EINVAL`; a microsecond value that happens to read as a valid `timespec` is waited on as one

Whether the console reads a microsecond timeout there in all cases, and what operation 1 does on it, is unverified. A call with size argument 0 is read unconditionally as a 4-byte microsecond timeout, matching callers like `libc.prx` and `PS5Util.prx`'s `zlqfTyrQSPk` wrapper which pass size 0 with a 32-bit microsecond count
 - [sceKernelSyncOnAddressWait](../../../core/libs/prx/libkernel/SyncOnAddress/src/SyncOnAddress.cpp) (libkernel) - the only known caller passes a null timeout and a name string as the fourth argument; the timeout is assumed to point to microseconds like the other kernel waits, and the name is ignored
 - [sceKernelSyncOnAddressWait8 / sceKernelSyncOnAddressWait16 / sceKernelSyncOnAddressWait32 / sceKernelSyncOnAddressWait64](../../../core/libs/prx/libkernel/SyncOnAddress/src/SyncOnAddress.cpp) (libkernel) - libc's `__std_atomic_wait_direct_8/16/32/64` pass a microsecond timeout or null and ignore the result; the by-value comparand, return values and the 2- and 8-byte alignment of Wait16 and Wait64 are assumed
 - [scePthreadRwlockDestroy, pthread_rwlock_destroy](../../../core/libs/prx/libkernel/Pthread/src/Rwlock.cpp) (libkernel) - measured on a PS5 (firmware 13.60): destroying a rwlock returns 0 whether it is free or held for reading or writing, and leaves 1 in the handle; every call on that handle then returns `EINVAL` until it is initialized again, and a zero handle is initialized on first use by the `scePthreadRwlock` calls as by the POSIX ones. A rwlock destroyed while held is not freed, so its memory leaks. Destroying a rwlock while another thread is acquiring it is not guarded

Subject: [PATCH 0154/1000] perf(libSceSysmodule): cache the unwind region of
 loaded images on Windows

sceSysmoduleGetModuleInfoForUnwind called VirtualQuery and GetMappedFileNameA on every call. VirtualQuery on a large image section costs time proportional to the section (2 us for 16 KiB, 51 us for 8 MiB, 167 us for 32 MiB), and a title that unwinds exceptions while loading calls it for every frame of every throw.

The region and file name of an address inside an image of the Windows loader's module list are kept per region and used while the loader still reports the same image (base, time stamp and size). Other addresses are queried every time.

+- [sceSysmoduleGetModuleInfoForUnwind](../../../core/libs/prx/libSceSysmodule/Export.cpp) (libSceSysmodule) - on Windows the region and file name of an address inside a loaded image are cached after the first lookup, because `VirtualQuery` on a large image section is slow. An entry is used only while the loader still reports the same image for the address (same base, time stamp and size). A page protection change inside the image after the first lookup, which would split or merge the region `VirtualQuery` reports, is not noticed. Addresses outside loaded images are queried every time

+- [libScePlayerSelectionDialog](../../../core/libs/prx/libScePlayerSelectionDialog/Export.cpp) - the player-selection dialog runs the common-dialog state machine but shows nothing and reports the user as having cancelled. `GetResult` writes only the first `int32` (`USER_CANCELED`); the rest of `ScePlayerSelectionDialogResult` (player list pointer and length) is not filled. EA SPORTS FC 27 (PPSA34015) fails to load `libScePlayerSelectionDialog.prx` without `Initialize`, `Open`, `UpdateStatus` and `GetResult` (`unresolved ELF import` / `GetLastError: 127`)

Subject: [PATCH 0156/1000] fix(relinker): trap guest GS accesses in Windows
 output instead of refusing the module

On Windows the host owns GS (the thread environment block), so a guest
instruction that reads or writes through GS cannot be translated the way FS
thread-pointer accesses are. Such an instruction refused the whole module.
Overwrite it in place with ud2 and NOP padding instead, so the module converts
and the instruction reports itself through the crash reporter if it runs.

Subject: [PATCH 0157/1000] test(relinker): cover GS loads, stores and ALU
 reads trapped in Windows output

Each form converts and is replaced by ud2 and NOP padding of its own length,
leaving the next instruction in place. The forms are the ones Wine's ntdll in
Prospero Win (PPSA99995) uses, plus a register-address form shorter than the
jump an FS access is rewritten with.

The Windows TLS builder returns early for a module without PT_TLS. A GS access
there must still be trapped; left in place it would read the host's thread
environment block.

The six signatures, 640-byte opaque state allocation and byte-count return follow [public PS5 decoder research](https://github.com/blackbearreloaded/ps5-hardware-audio-decoding/blob/26be5a12f92b2cdc67f8a9e082fd69ae0e9a35a2/docs/DECODING.md#direct-opus-abi) and [ProsperoRadio](https://github.com/blackbearreloaded/ProsperoRadio/blob/2c4029c3a8f43e9e1dfef98374d94d99b14d745d/src/opus_decoder.cpp). Console PCM equivalence and error codes are unverified. Other sample rates, packet loss concealment, invalid inputs and termination with live decoders throw. Context identifiers and host decoder state are private registries; the firmware's opaque state layout and error recovery are unknown.
+- [libSceOpusDec](../../../core/libs/prx/libSceOpusDec/Export.cpp) uses FFmpeg for mono/stereo signed-16 decoding at the creation rates the research lists: 8000, 12000, 16000, 24000 and 48000 Hz. The six signatures, 640-byte opaque state allocation and byte-count return follow [public PS5 decoder research](https://github.com/blackbearreloaded/ps5-hardware-audio-decoding/blob/26be5a12f92b2cdc67f8a9e082fd69ae0e9a35a2/docs/DECODING.md#direct-opus-abi) and [ProsperoRadio](https://github.com/blackbearreloaded/ProsperoRadio/blob/2c4029c3a8f43e9e1dfef98374d94d99b14d745d/src/opus_decoder.cpp). Console PCM equivalence and error codes are unverified. Other sample rates, packet loss concealment, invalid inputs and termination with live decoders throw. Context identifiers and host decoder state are private registries; the firmware's opaque state layout and error recovery are unknown.
 - [sceOpusDecDecode](../../../core/libs/prx/libSceOpusDec/Export.cpp) (libSceOpusDec) returns exactly the packet's duration, as libopus does. FFmpeg resamples narrowband SILK from 8 kHz and holds back 24 samples of the first narrowband packet after the decoder starts or after a packet of another bandwidth, releasing them with the next packet that is not narrowband. The decoder keeps FFmpeg's output in order and pads the start with silence, so such a packet begins with 24 samples (0.5 ms) of silence and the output after it is 24 samples late; libopus has no such gap
+- [sceOpusDecDecode](../../../core/libs/prx/libSceOpusDec/include/OpusDecoder.hpp) (libSceOpusDec, libSceOpusCeltDec) decodes at 48000 Hz and converts to a lower creation rate with FFmpeg's resampler, where libopus decodes at that rate directly. The resampler's filter delay is padded with silence at the start of the stream like the narrowband delay above, so the output is late by that delay and is not sample-identical to libopus; which of the two the console matches is not measured

Subject: [PATCH 0162/1000] fix(libkernel): use precise waits for select and
 poll on pipes on Windows

On Windows, select over pipes polls readiness in HostPoll and sleeps
std::this_thread::sleep_for(1 ms) between rounds, and poll with pipes
but no native sockets sleeps sleep_for(slice). winpthreads ends these
sleeps on 15.6 ms timer ticks (#1471), so a guest select or poll with a
short timeout on an idle pipe waits about 15 ms per call instead of its
timeout, and a longer wait checks the pipes only every 15.6 ms.

Both paths now sleep with PreciseSleepUntil. Each sleep requests at
most 1 ms and ends no later than the deadline; the old HostPoll sleep
could pass its deadline by a whole tick. poll on pipes also stops
spinning through the last partial millisecond before its deadline,
where the remaining time truncated to 0 ms and no sleep was made.
Infinite timeouts still sleep 1 ms per round.

The pipes are now checked about every 1.5 ms instead of every 15.6 ms:
a pipe that becomes ready is noticed sooner, and a thread blocked on an
idle pipe wakes about ten times as often. A 1 ms poll on an idle pipe
returns after about 1.5 ms instead of spinning for 1 ms.

guest_poll times 20 polls with a 2 ms timeout on an empty pipe read end
and guest_select times 20 selects with a 1 ms timeout on it; each set
must take less than 200 ms. A 1 ms poll does not reach the old sleep,
because the remaining time truncates to 0 ms and the old loop spins
until the deadline, so the poll check uses 2 ms. On Windows Server 2025
both sets took 312 ms before this change and about 50 ms and 30 ms
after it.

Subject: [PATCH 0164/1000] fix(agc): refuse last-vertex strips only for reads
 of a vertex slot

With fragmentShaderBarycentric (RADV, NVIDIA), v_interp_p1_f32 and
v_interp_p2_f32 are translated as P0 + I * P10 + J * P20 over the
per-vertex values, so every smooth input became per-vertex. A triangle
strip drawn with PROVOKING_VTX_LAST then threw "last provoking vertex
with explicit per-vertex triangle-strip interpolation is unsupported"
for any shader that interpolates, which stops OliSe Player (PPSA01153)
and RetroArch's ES-DE frontend (PPSA99169), both ps5-opengl titles
whose shaders use only v_interp_p1/p2.

I and J come from gl_BaryCoordKHR[1] and [2], in the same vertex order
as the pervertexEXT values, so the result is b0 * v0 + b1 * v1 + b2 * v2
whatever order the device gives an odd strip triangle. Only a shader
that reads a slot itself depends on that order. The translator now
records the inputs read through v_interp_mov_f32 or 16-bit
interpolation, FragmentParameter carries that as vertexOrder, and the
strip check refuses those alone. 16-bit interpolation would cancel out
the same way but has not been checked, so it stays refused.

Subject: [PATCH 0165/1000] test(agc): check the strip guard on interpolated
 and slot-read inputs

A pixel shader that interpolates its input with v_interp_p1/p2 compiles
to a per-vertex input without vertexOrder and passes a last-vertex
strip; the same input read through v_interp_mov P10 is vertexOrder and
still throws on a strip, not on a list. The synthetic matrix gets
vertexOrder as a third axis. The first check fails with the guard on
perVertex, the second without the v_interp_mov record.

The device still reads guest memory when the dispatch is issued; when that memory no longer matches the capture, the dispatch is resolved again from current memory.
 - [PA_CL_CLIP_CNTL](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - `DX_LINEAR_ATTR_CLIP_ENA` (bit 24) clear is drawn like bit 24 set, with Vulkan's clipping of `NoPerspective` outputs; what a clear bit changes on the console is undocumented.
 - [10_11_11 unorm color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) render into R32_UINT attachments: the pixel shader packs each export, rounded to nearest even like format-30 image stores, which is assumed to match the CB's conversion.

Last mode throws without `VK_EXT_provoking_vertex`, for generated rectangle, mesh or tessellation primitives, explicit per-vertex flat inputs, and triangle strips with per-vertex inputs, whose [ordering depends on the device](https://docs.vulkan.org/refpages/latest/refpages/source/VkPhysicalDeviceFragmentShaderBarycentricPropertiesKHR.html). A FLAT_SHADE input without pass-through that is read through `v_interp_mov_f32` P10 and not P20 [returns the provoking vertex's value](../../../core/shader/recompiler/Optimization/src/ShaderInfoCollector.cpp), like P0. ps5-opengl reads every flat input that way, and its driver passes the GL 4.6 CTS on a PS5 (#1413).

A FLAT_SHADE input without pass-through that is read through `v_interp_mov_f32` P10 and not P20 [returns the provoking vertex's value](../../../core/shader/recompiler/Optimization/src/ShaderInfoCollector.cpp), like P0. ps5-opengl reads every flat input that way, and its driver passes the GL 4.6 CTS on a PS5 (#1413).

 - [Dual-source blending](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) takes the MRT1 export as the second source of the MRT0 blend, as RADV and radeonsi program it; what the CB does with other export or target layouts is unknown, so they throw.
 - [DB_SHADER_CONTROL.CONSERVATIVE_Z_EXPORT](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderInputState.cpp) (libSceAgcDriver) becomes `DepthLess`/`DepthGreater`. For a pixel shader that breaks the promise, the host driver decides whether its interpolated Z is depth-tested before shading; what the console does then was not measured.
 - [DB_SHADER_CONTROL.STENCIL_TEST_VAL_EXPORT_ENABLE](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) becomes `FragStencilRefEXT` when available, taken from the second MRTZ channel of the 32_GR and 32_ABGR formats as Mesa's AMD drivers write it ([`emit_ps_mrtz_export`](https://gitlab.freedesktop.org/mesa/mesa/-/blob/3e32b0e1f132231b7a972c1b0b5b06c7e16cf8b9/src/amd/common/nir/ac_nir_lower_ps_late.c#L194)); the console was not measured. The host value is the test value of both faces and what `REPLACE_TEST` writes, so a stencil operation that writes all ones or the operation value throws with it, as do a stencil clear draw, the UINT16_ABGR layout and `STENCIL_OP_VAL_EXPORT_ENABLE`. A device without the extension uses the bounded replay described above.

Subject: [PATCH 0170/1000] fix(shader): allow 32 sampler pairs per shader

A pixel shader of MXGP 26 (PPSA30839) uses 17 samplers, over the limit
of 16 sampler pairs. The sampler heap now holds 64 descriptors, ShaderData
grows by 32 sampler metadata records and the runtime ABI version moves
to 13.

 - [sceKernelSyncOnAddressWait](../../../core/libs/prx/libkernel/SyncOnAddress/src/SyncOnAddress.cpp) (libkernel) - the only known caller passes a null timeout and a name string as the fourth argument; the timeout is assumed to point to microseconds like the other kernel waits, and the name is ignored
 - [sceKernelSyncOnAddressWait8 / sceKernelSyncOnAddressWait16 / sceKernelSyncOnAddressWait32 / sceKernelSyncOnAddressWait64](../../../core/libs/prx/libkernel/SyncOnAddress/src/SyncOnAddress.cpp) (libkernel) - libc's `__std_atomic_wait_direct_8/16/32/64` pass a microsecond timeout or null and ignore the result; the by-value comparand, return values and the 2- and 8-byte alignment of Wait16 and Wait64 are assumed
 - [scePthreadRwlockDestroy, pthread_rwlock_destroy](../../../core/libs/prx/libkernel/Pthread/src/Rwlock.cpp) (libkernel) - measured on a PS5 (firmware 13.60): destroying a rwlock returns 0 whether it is free or held for reading or writing, and leaves 1 in the handle; every call on that handle then returns `EINVAL` until it is initialized again, and a zero handle is initialized on first use by the `scePthreadRwlock` calls as by the POSIX ones. A rwlock destroyed while held is not freed, so its memory leaks. Destroying a rwlock while another thread is acquiring it is not guarded

An untouched adaptive static initializer (slot value 1) therefore returns `EPERM`; the test covers this, an uninitialized slot, a mutex owned by another thread, and the destroyed marker for both timed and untimed sce and POSIX waits. A recursive mutex locked several times is released completely for the wait and relocked to the same depth afterwards, as FreeBSD libthr does (`_mutex_cv_unlock`, `_mutex_cv_lock`).

A recursive mutex locked several times is released completely for the wait and relocked to the same depth afterwards, as FreeBSD libthr does (`_mutex_cv_unlock`, `_mutex_cv_lock`). These FreeBSD-derived behaviors remain unverified on console hardware. Cancellation follows the [POSIX condition wait contract](https://pubs.opengroup.org/onlinepubs/9799919799/functions/pthread_cond_clockwait.html): the original mutex and recursive depth are restored before cleanup, and a canceled waiter forwards a wake to the remaining waiters. The host condition state is retained across mutex reacquisition so the guest can destroy and free its condition after notification; cancellation ordering and signal replacement are not measured on a console

 - [scePthreadAttr setters and getters](../../../core/libs/prx/libkernel/Pthread/src/Attr.cpp) (libkernel) - measured on a PS5 (firmware 13.60): a null or uninitialized attribute returns `EINVAL`, as does a null output of the stack size, detach state and scheduling parameter getters; a policy other than 1 and 3, an inheritance other than 0 and 4, or a priority outside 256 to 767 (or a null parameter) returns `ENOTSUP` (`0x8002002D`); a detach state other than 0 and 1 and a stack size below 16384 return `EINVAL`; any affinity mask is accepted. A null attribute pointer to `scePthreadAttrInit` and a null output of `scePthreadAttrGetaffinity` crashed the payload, so they still throw. A new attribute holds a 64 KiB stack size on the console and 1 MiB here, which the host code that runs on guest threads needs
 - [sceKernelGetAvailableCpumask](../../../core/libs/prx/libkernel/Pthread/src/Thread.cpp) (libkernel) - returns the default thread affinity, 0x1FFF (CPUs 0 to 12), as KytyPS5 does. Titles pin threads within it (PPSA02664 passes 0x1FFB, Hades II PPSA36082 0x3 and 0x3F); whether CPU 13 is available to a title is not confirmed

 - `--to-intel` does not lower RDPRU/MCOMMIT; the [matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp) fails the relink instead.
 - The length-changing path of the [instruction rewriter](../../../core/relinker/codegen/src/x86/X64InstructionRewriter.cpp) is not used by the [converter](../../../core/relinker/codegen/src/Amd64OnlyConverter.cpp): it does not adjust data-to-code references (relocations, FDEs, jump tables) or segment sizes, so every substitution keeps the instruction length.
 - A `PT_SCE_RELRO` segment that no `PT_LOAD` covers, the PS4 layout, is [loaded](../../../core/relinker/relinker/src/parsing/ElfReader.cpp) as a read-write `PT_LOAD` and stays writable after relocation; FreeBSD rtld makes `PT_GNU_RELRO` read-only once relocation is done, and what the console does with `PT_SCE_RELRO` is not checked.
+- In Windows output, a guest instruction that addresses memory through GS becomes `UD2` and NOP padding of its own length ([TLS builder](../../../core/relinker/elfpatcher/src/windows/WindowsTlsBuilder.cpp)): the host owns GS, and the guest GS base that FreeBSD's `sysarch(AMD64_SET_GSBASE)` would set is not emulated. A converted module runs until such an instruction is reached, which then faults. Prospero Win (PPSA99995) has six in its Wine `ntdll`.
 - In executables with a `PT_SCE_DYNLIBDATA` segment, the PS4 layout, the executable segment also holds read-only data after the code (CUSA00900: 37 MiB after its last function). The [relinker pipeline](../../../core/relinker/relinker/src/pipeline/RelinkerPipeline.cpp) therefore scans for syscalls and import call sites only up to the end of the PLT that follows the last function of the unwind table; code after the PLT without an unwind entry is not scanned. `--to-intel` and the `unused-filter=1` and `unused-filter=2` analyses are not limited this way.
 - In executables and guest modules with a `PT_SCE_DYNLIBDATA` segment, the [code analysis](../../../core/relinker/relinker/src/analysis/CodeInstructionCollector.cpp) of the Windows and macOS outputs follows code only from the end of `PT_INTERP` to the end of the PLT after the last function of the unwind table, the end the pipeline's scans above use; a guest module with PLT relocations and no PLT after its last unwind function fails as the executable does. Code after that PLT is not analyzed: a TLS access in it is not rewritten, an entry point or pointer into it is ignored, and a function symbol or init/fini array entry pointing into it fails the conversion.
 - A relocation against a dynamic symbol entry that is all zero, like the null symbol, takes the value 0 plus its addend, as the gABI defines for `STN_UNDEF` ([pipeline](../../../core/relinker/relinker/src/pipeline/RelinkerPipeline.cpp)). The Linux output imports such an entry as an unnamed weak symbol, which the host loader resolves to 0; the Windows and macOS outputs write the value into the slot ([relocation builder](../../../core/relinker/elfpatcher/src/windows/WindowsRelocationBuilder.cpp)). What the console's loader does with such an entry is not measured. OliSe Player (PPSA01153) has seven of them, and its code calls through those slots only when they are not 0 ([#4437](https://github.com/boykopovar/AnyPS5/issues/4437)).

Subject: [PATCH 0178/1000] feat(agc): accept SAMPLE_STREAMOUTSTATS events
 without a destination in EVENT_WRITE

EVENT_WRITE (PM4 opcode 0x46) with event type SAMPLE_STREAMOUTSTATS1-3
(0x01-0x03) or SAMPLE_STREAMOUTSTATS (0x20) failed submission validation
with "EVENT_WRITE event type 1 is not implemented". Minecraft Preview
(PPSA19639, discussion #1277, stop 9) submits a 2-dword type-1 packet
while entering a world, and the GPU thread aborted intermittently.

The four values are VGT_EVENT_TYPE entries in Linux
drivers/gpu/drm/amd/include/navi10_enum.h L14155-14188 at
0fcb05b72344f40806cbe810de8872f1698bf053.
drivers/gpu/drm/amd/amdgpu/nvd.h L326-347 at the same commit documents
these events only with the sampling index (3, or
EVENT_INDEX__SAMPLE_STREAMOUTSTATS* 8-11 on gfx10), followed by
ADDRESS_LO/HI. The 2-dword index-0 packet has no destination dwords, and
what the CP does with it is neither documented nor measured. AnyPS5 does
not emulate the VGT stream-out counters, so there is nothing to sample.
Packet execution already skips EVENT_WRITE.

These event types are now accepted on the graphics queue as 2-dword
packets with event index 0. The sampling indices 3 and 8-11 throw that
stream-out statistics sampling to memory is not implemented, before the
size and reserved-bit checks. Other indices, other sizes and the compute
queue still throw.

sceAgcDcbEventWrite ignores the address for every event type except 0x38
and 0x39, so a call with one of these event types and an address now
builds a packet that validates and writes nothing. This is recorded in
docs/dev/debt/libSceAgcDriver.md with the unmeasured hardware behaviour.

 - [1_5_5_5 color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) render into A1R5G5B5. AMD formats keep the first component in the least significant bits (X in bits 0-4, Y in 5-9, Z in 10-14, W in bit 15, as in the [fpPS4](https://github.com/red-prig/fpPS4) `kSurfaceFormat1_5_5_5` doc comment and as measured for textures in the packed 16-bit textures entry), while A1R5G5B5 keeps R in bits 10-14 and B in bits 0-4, so the pixel exports are written with X and Z exchanged, which makes the stored bits follow the guest layout. The decoded format, component mapping and write mask are tested, and an execution test draws 32_ABGR exports into tiled and linear targets and compares every stored texel with the guest layout on the host device; the export direction is not measured on a PS5. Only UNORM with the standard component swap is accepted. Constant blend colors go through the same component-swap handling as other targets with that export mapping (`0xc6`), which is not tested for this format. PPSA06699 renders into this format.
 - [COPY_DATA from the GPU clock](../../../core/libs/prx/libSceAgcDriver/Execution/src/Pm4.cpp) (libSceAgcDriver, `SRC_SEL` 9) writes the host steady clock in 10 ns ticks when the packet runs, the same counter as the `RELEASE_MEM` timestamp, not the console's GPU clock. The `COPY_DATA` cache policy fields are accepted and have no effect.
 - [COPY_DATA from a register](../../../core/libs/prx/libSceAgcDriver/Execution/src/Pm4.cpp) (libSceAgcDriver, `SRC_SEL` 0) copies the value the queue holds for a shader, context or user config register (`COUNT_SEL` two consecutive ones) and throws for a register with no value. A dispatch records `COMPUTE_DISPATCH_INITIATOR` and, for `DISPATCH_DIRECT`, `COMPUTE_DIM_X/Y/Z` in the shader registers; `DISPATCH_INDIRECT` clears the three counts. Neither the register values the CP writes nor the copy's ordering against in-flight dispatches have been measured on hardware.
+- [EVENT_WRITE stream-out statistics events](../../../core/libs/prx/libSceAgcDriver/Execution/src/Pm4.cpp) (libSceAgcDriver, opcode 0x46) - `SAMPLE_STREAMOUTSTATS1`-`3` and `SAMPLE_STREAMOUTSTATS` (event types 0x01-0x03 and 0x20 in [navi10_enum.h](https://github.com/torvalds/linux/blob/0fcb05b72344f40806cbe810de8872f1698bf053/drivers/gpu/drm/amd/include/navi10_enum.h#L14155-L14188)) are accepted on the graphics queue as a 2-dword packet with event index 0 and do nothing. [nvd.h](https://github.com/torvalds/linux/blob/0fcb05b72344f40806cbe810de8872f1698bf053/drivers/gpu/drm/amd/amdgpu/nvd.h#L326-L347) documents these events only with the sampling index (3, or `EVENT_INDEX__SAMPLE_STREAMOUTSTATS*` 8-11 on gfx10); the index-0 packet has no destination dwords, and what the CP does with it is neither documented nor measured on hardware. AnyPS5 does not emulate the VGT stream-out counters, so there is nothing to sample. The sampling indices throw that sampling to memory is not implemented, and other indices, other sizes and the compute queue throw. [sceAgcDcbEventWrite](../../../core/libs/prx/libSceAgc/DcbFlow/src/Sync.cpp) ignores the address for every event type except 0x38 and 0x39, so a call with one of these event types and an address builds the index-0 packet: nothing is written and nothing throws. Whether the console's builder emits a sampling packet for an address is not known.
 - [INDEX_ATTRIBUTES_INDIRECT](../../../core/libs/prx/libSceAgcDriver/Execution/src/Pm4.cpp) (libSceAgcDriver, opcode 0x91) loads INDEX_BASE, INDEX_BUFFER_SIZE (in indices) and INDEX_TYPE from the 16-byte record at `attribute_base + attribute_index * 16`, read when the packet runs. The record layout (address low, address high, size, type) is PAL's [`IndexAttribIndirect`](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/hw/gfxip/gfx9/gfx9Chip.h#L60-L67) and the packet is the one [`BuildIndexAttributesIndirect`](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/hw/gfxip/gfx9/gfx9CmdUtil.cpp#L2586-L2613) writes; neither is measured on a PS5 or seen in a title. `indirect_mode` 1 (`addr_offset`, which only PAL's ExecuteIndirect path emits) throws, and so does a record whose index type is above 3, as INDEX_TYPE does.
 - [16-bit RGBA color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) support the standard and the alternate (`COMP_SWAP` 1) component order. Alternate swaps red and blue in shader exports, write masks and constant-color blend factors, following `ac_translate_colorswap` in [Mesa 26.2.2 ac_formats.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/amd/common/ac_formats.c). The reverse orders (`COMP_SWAP` 2 and 3) keep throwing when blending, and simultaneous targets requiring conflicting blend constants throw. Console equivalence has not been measured on hardware.
 - [UINT16_ABGR color exports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - export format 7 is accepted only into an unsigned integer target, and each 16-bit value reaches the target unchanged; a value beyond a narrower target's range (`R8_UINT`) is undefined in Vulkan, and whether the console clamps or truncates it is not confirmed. SINT16_ABGR (8) throws

Subject: [PATCH 0179/1000] feat(libSceNpManager): register NP state callbacks
 and report signed-out from sceNpCheckCallback

sceNpRegisterStateCallback and sceNpRegisterStateCallbackA stored nothing,
the unregister calls always succeeded and sceNpCheckCallback did nothing,
so a title that waits for its NP state callback never learned the user's
state. #1277 reports that Minecraft Preview (PPSA19639) needs the callback
(stop 2).

sceNpRegisterStateCallbackA now keeps up to 8 callbacks and returns the
slot plus 1. A null callback returns INVALID_ARGUMENT, a callback that is
already registered CALLBACK_ALREADY_REGISTERED and a ninth one
CALLBACK_MAX (0x8055001D). sceNpUnregisterStateCallbackA returns
INVALID_ARGUMENT for an id outside 1..8 and CALLBACK_NOT_REGISTERED for an
empty slot. The legacy sceNpRegisterStateCallback keeps one callback with
the same errors. The rules follow shadPS4
src/core/libraries/np/np_manager.cpp @15abf68c9b52 (RegisterStateCallbackA
and UnregisterStateCallbackAById L857-L901, the legacy pair L981-L1005,
ORBIS_NP_STATE_CALLBACK_MAX L36) and np_error.h L38.

Each registration is marked pending. sceNpCheckCallback takes the pending
registrations under the lock and calls them after releasing it, on the
calling thread, with SIGNED_OUT for the initial user 0x10000000. For the A
form this follows KytyPS5 src/libs/network.cpp @9e41d8320a27
(NpRegisterStateCallbackA L4021-L4034 marks the registration pending,
NpCheckCallback L3959-L3974 delivers it once). KytyPS5 never calls the
legacy callback (NpRegisterStateCallback and NpUnregisterStateCallback,
L4009-L4019, do nothing). The legacy callback is called as
(user, SIGNED_OUT, nullptr, userdata), as in shadPS4, which passes an NpId
only for SIGNED_IN (L823, L938-L940).

shadPS4 queues SIGNED_OUT from the user service login event instead
(DispatchPendingNpStateCallbacks L903-L962), and the same event calls the
reachability callback once with UNAVAILABLE (L922-L931, L959-L961). The
reachability callback is still not called here. These differences and the
unmeasured console behaviour are recorded in
docs/dev/debt/libSceNpManager.md.

 - [NP reachability callbacks](../../../core/libs/prx/libSceNpManager/Export.cpp) retain one callback and its user data; duplicate registration and unregistering an absent callback return the errors used by [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/945dbc3cc3eee80ac3e053b438502ed936fa6bb2/src/core/libraries/np/np_manager.cpp). No callback is delivered because the existing NP model remains signed out with reachability unavailable.

Each registration gets `SIGNED_OUT` for the initial user (0x10000000) once, from the next `sceNpCheckCallback` on the calling thread. For the A form this follows [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/9e41d8320a2774b303fbad344c2347e8d0292e83/src/libs/network.cpp#L3959-L3974), whose [sceNpRegisterStateCallbackA](https://github.com/KytyPS5/KytyPS5/blob/9e41d8320a2774b303fbad344c2347e8d0292e83/src/libs/network.cpp#L4021-L4034) marks the registration pending. KytyPS5 never calls the legacy callback ([sceNpRegisterStateCallback](https://github.com/KytyPS5/KytyPS5/blob/9e41d8320a2774b303fbad344c2347e8d0292e83/src/libs/network.cpp#L4009-L4019) stores nothing); it is called as `(user, SIGNED_OUT, nullptr, userdata)`, as in shadPS4, which passes an NpId only for `SIGNED_IN` ([L823](https://github.com/shadps4-emu/shadPS4/blob/15abf68c9b52c4b04d094f2837719fdb871021f3/src/core/libraries/np/np_manager.cpp#L823), [L938-L940](https://github.com/shadps4-emu/shadPS4/blob/15abf68c9b52c4b04d094f2837719fdb871021f3/src/core/libraries/np/np_manager.cpp#L938-L940)). shadPS4 instead queues `SIGNED_OUT` from the user service login event and delivers it from `sceNpCheckCallback` ([DispatchPendingNpStateCallbacks](https://github.com/shadps4-emu/shadPS4/blob/15abf68c9b52c4b04d094f2837719fdb871021f3/src/core/libraries/np/np_manager.cpp#L903-L962)); the reachability callback is not given an initial `UNAVAILABLE`, unlike that function ([L922-L961](https://github.com/shadps4-emu/shadPS4/blob/15abf68c9b52c4b04d094f2837719fdb871021f3/src/core/libraries/np/np_manager.cpp#L922-L961)). A callback being delivered when another thread unregisters it is still called once. When and how often the console calls the state callbacks, and the errors, are not measured

Subject: [PATCH 0180/1000] feat(libSceVideoOut): export the hardware cursor
 functions as not implemented

sceVideoOutCursorEnable, sceVideoOutCursorDisable,
sceVideoOutCursorSetImageAddress and sceVideoOutCursorSetPosition are imported
by Prospero Win's (PPSA99995) Vulkan module, so on Windows, where imports are
bound at load, the title cannot load without them. They report that they are
not implemented when called.

Subject: [PATCH 0181/1000] test(libSceVideoOut): check that the cursor
 functions report they are not implemented

guest_video_out_cursor calls each of the four cursor functions with a handle,
a cursor index, an image and a position, and requires the "not implemented"
error. Without the exports it does not link.

 ### Unknown function info
 
 - [sceVideoOutDeleteVrrActiveStatusEvent](../../../core/libs/prx/libSceVideoOut/src/Event.cpp) (libSceVideoOut, NID `-q-vbO859Tw`) - the name hashes to the NID PPSA02530 imports and is listed in [sce_symbols](https://github.com/zecoxao/sce_symbols) `aerolib.csv` at `fe2cc2948e`. The signature `(eq, handle)` and the behaviour, removing the handle's VRR status registration from the queue as the other `Delete*Event` calls do, follow sceVideoOutAddVrrActiveStatusEvent; no title has been observed calling it
+- [sceVideoOutCursorEnable, sceVideoOutCursorDisable, sceVideoOutCursorSetImageAddress, sceVideoOutCursorSetPosition](../../../core/libs/prx/libSceVideoOut/Unimplemented.cpp) (libSceVideoOut, NIDs `UPZWCH8qTM4`, `fEPEwROdCwM`, `u-9bhWQApq8`, `N17AK88NdD0`) - the names hash to the NIDs Prospero Win (PPSA99995) imports, and the parameter lists `(handle, index, address)`, `(handle, index)`, `(handle, index, address)` and `(handle, index, x, y)` follow its [declarations](https://github.com/mpereiraesaa/prospero-win/blob/644e32e400c555e340d507383398c5d21b39b0b0/wine/ps5/pw_vulkan_radv.c#L65-L68). The cursor image's format and size and the console's return values are not known; the functions report that they are not implemented.
 - [sceVideoOutGetOutputStatusWithVrr](../../../core/libs/prx/libSceVideoOut/src/Output.cpp) (libSceVideoOut, NID `gWT7X8H0bYs`) - `(int handle, void* status)`, the 80-byte layout and the return codes follow the clean-room description in #2746. Bytes 0-47 are `sceVideoOutGetOutputStatus`'s; bytes 48-53, which the console copies from an internal query whose fields are not established, are written as zero, as are the rest, so the 16-bit value at byte 52 never adjusts `refreshRate`. A null `status` returns `0x80290002` and an unknown handle `0x8029000B`. The console's earlier global-flag check (`0x8029001C`) and its object-field check (`0x8029001B`) test states that are not modelled and are never reported.
 - [sceVideoOutRegisterBuffers2](../../../core/libs/prx/libSceVideoOut/src/Buffer.cpp) (libSceVideoOut) - buffer option 8 (STRICT_COLORIMETRY) is presented as option 0, with the stored values unchanged; what the console changes for it is unknown. Only options 0 and 8 are accepted
 - [sceVideoOutAddBufferAttributeOption](../../../core/libs/prx/libSceVideoOut/src/Buffer.cpp) (libSceVideoOut, NID `MBlv8YWoyOk`) - the signature `(VideoOutBufferAttribute2*, uint64_t option)` comes from [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/60977b29103452b9681ae10c7a9011d44965bf16/src/SharpProspero/Interop/VideoOut/VideoOut.cs#L174-L176) and the call site in PPSA25380, which passes 0x20 and ignores the result. The option is ORed into `attribute->option`; whether the console validates the bits, keeps them elsewhere or fails on an unknown option is unknown. A null attribute throws. Option 0x20 makes `sceVideoOutRegisterBuffers2` throw, as every option other than 0 and 8; what it selects for an overlay buffer is unknown

Subject: [PATCH 0188/1000] feat(libc): reserve the guest arena on macOS

macOS has no /proc/self/maps or MAP_FIXED_NOREPLACE, so the arena never came up and every guest allocation threw. Enumerate host regions with mach_vm_region and reserve free chunks with a fixed mach_vm_map, which fails instead of replacing. This skips dyld, the Rosetta runtime, and ranges the kernel never lets a process map (0x10_0000_0000-0x70_0000_0000). The POSIX commit/protection paths now build on macOS unchanged. Adds standalone guest_arena tests (x86_64 under Rosetta and arm64).

   - a system call that writes into a protected page fails with `EFAULT` instead of faulting. `GuestArena::HostWrite` lifts the protection for the calls it brackets (file reads and socket receives); a host call that writes guest memory without it (`clock_gettime` and the like into a watched page) fails;
   - code that changes the protection of watched pages, or maps over them, has to call `GuestWriteWatchProtectionChanged`, and code that asks the kernel for a page's protection has to ask `GuestWriteWatchProtection` first, since a watched page is read-only between a collection and the next write. Nothing calls either yet: the macOS memory paths are not in the tree;
   - the handler is installed when libc loads and passes other faults to the handler installed before it. A handler installed later has to do the same.
+- On macOS the [guest arena](../../../core/libs/prx/libc/src/GuestArena.cpp) finds host regions with `mach_vm_region` and reserves the rest with a fixed `mach_vm_map`, which fails instead of replacing, as macOS has no `/proc/self/maps` or `MAP_FIXED_NOREPLACE`. The kernel keeps 0x10_0000_0000-0x70_0000_0000 unmappable for every process (max protection none; macOS 26.5, M1 Pro, arm64 and x86_64 under Rosetta), and dyld and the Rosetta runtime sit near 0x2_0200_0000 and 0x3_0400_0000, so a guest mapping fixed inside those ranges fails where the console places it; mappings without a fixed address are placed around them.
 - [sceKernelSync](../../../core/libs/prx/libc/src/General.cpp) (libkernel) flushes only the host files and directories recorded through `RecordWrittenPath_nid_no_patch` (the libc, libkernel, save data and app content file functions) and their changed parent directories. A host write in a library that does not record its path is not flushed by `sceKernelSync`
 - [sceKernelSync](../../../core/libs/prx/libc/src/General.cpp) (libkernel) on Windows skips a recorded file it cannot open for writing (read-only, or held open by a handle that denies write sharing), since `FlushFileBuffers` needs a writable handle. On Linux, it skips a recorded file it cannot open for reading. Such a file's data may not reach the disk before a host crash; the guest reads the same data either way
 - [`fopen` streams](../../../core/libs/prx/libc/src/FileAndHeap.cpp) (libc) on Windows share delete access, like the descriptors [`sceKernelOpen`](../../../core/libs/prx/libkernel/File/src/Open.cpp) opens, so a file the guest holds open can be removed or renamed. A stream reopened with `freopen` still goes through `_wfreopen`, which does not share delete access. On Windows, opening a directory in a read mode fails with `EACCES`, where FreeBSD opens it; directory streams are not emulated

Subject: [PATCH 0190/1000] fix(agc): print the VGT_TF_PARAM and
 VGT_LS_HS_CONFIG fields of a refused tessellation draw

A tessellation draw whose domain, partitioning or output topology the
reference path does not support was refused with only VGT_SHADER_STAGES_EN,
so a log did not show which configuration was refused. The refusal now
prints VGT_TF_PARAM with TYPE, PARTITIONING and TOPOLOGY, and
VGT_LS_HS_CONFIG with NUM_PATCHES, HS_NUM_INPUT_CP and HS_NUM_OUTPUT_CP.
The fields come before the explanation, so the reason that the
APS5_CAPTURE_TRACE log cuts at 256 characters still holds all of them.

Field and enumerator names are those of Mesa's
src/amd/registers/gfx103.json (enums VGT_TESS_TYPE, VGT_TESS_PARTITION and
VGT_TESS_TOPOLOGY). A value with no name there is printed as a number only.
The accepted configurations are unchanged.

The new UnsupportedTessellationFieldTests drives DecodeState into the
refusal with power-of-two triangle and quad patches, an isoline domain,
line and point output and unnamed TYPE, PARTITIONING and TOPOLOGY values,
and checks the decoded fields of both registers, including the order of
the input and output control-point counts.

Subject: [PATCH 0192/1000] feat(libkernel): add munlockall export

Follows mlockall (#4386) for XPSemu (PPSA97358, QEMU os-posix.c), which
imports munlockall (NpLBpgVV7PU) from libkernel.prx. Predicted stop:

  FAIL: unresolved ELF import NpLBpgVV7PU from libkernel.prx

The NID is computed with tools/nid_names.py and matches aerolib.

Follows FreeBSD 11.4 sys/vm/vm_mmap.c sys_munlockall
(8c639945a44588f6cfdddfb057bb5aad88735da0): checks PRIV_VM_MUNLOCK,
clears wire state and returns 0. To match, munlockall unlocks ranges
locked by mlock (through VirtualUnlock on Windows, tolerating
ERROR_NOT_LOCKED, and munlockall on Linux).

 - [msync](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) follows FreeBSD 11's `kern_msync` and `vm_map_sync`, not measured on the console: the address is rounded down to the page, a range that wraps is `EINVAL`, as is `MS_ASYNC` with `MS_INVALIDATE`, and a range whose start or any page is not mapped (as `sceKernelVirtualQuery` reports it, reservations included) is `ENOMEM`; a page unmapped from inside a larger mapping still counts as mapped there, since `sceKernelVirtualQuery` keeps reporting the whole mapping. The guest has no file mappings, so a successful call writes nothing back. `MS_INVALIDATE` on a mapped range throws: FreeBSD returns `EBUSY` when the range holds `mlock`ed pages, and locked pages are not tracked
 - [madvise](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) accepts `MADV_PROTECT` (10) as a no-op hint without modifying process protection. FreeBSD 11's `kern_madvise` (`sys/vm/vm_mmap.c`) handles it before the address check, ignores the address and length, and calls `kern_procctl(..., PROC_SPROTECT, PPROT_SET)`, which requires `PRIV_VM_MADV_PROTECT` and fails with `EPERM` without it. Returning 0 unconditionally assumes the calling process is privileged. Console behaviour is unverified
 - [mincore](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) follows FreeBSD 11's `sys_mincore` (`sys/vm/vm_mmap.c`), not measured on the console: the address is rounded down to the page, length 0 returns 0, a null vector over a mapped range returns `EFAULT`, an overflowing range or any unmapped page in the range (as reported by `sceKernelVirtualQuery`) returns `ENOMEM`. For valid ranges, a page reports `MINCORE_INCORE` (0x1) when `sceKernelVirtualQuery` reports it committed and 0 when it is only reserved; actual residency, referenced and modified bits are not modelled. Length 0 returns 0 when the start page is mapped and `ENOMEM` otherwise, and the range and mapping checks come before the null vector `EFAULT`, as in `kern_mincore` Java 25 LAN / DNS (PPSA99869) imports it
-- [mlockall](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) returns `EINVAL` for zero or unknown flags. Valid `MCL_CURRENT` throws because it would lock host stacks, heaps, modules and driver mappings along with guest memory; `MCL_FUTURE` throws because later mappings are not tracked for locking. On main, XPSemu (PPSA97358) fails to load at this import; its `MCL_CURRENT | MCL_FUTURE` calls execute only when `-overcommit mem-lock=on` is enabled. The call has not been observed in a run with this implementation.
+- [mlockall, munlockall](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) - `mlockall` returns `EINVAL` for zero or unknown flags. Valid `MCL_CURRENT` throws because it would lock host stacks, heaps, modules and driver mappings along with guest memory; `MCL_FUTURE` throws because later mappings are not tracked for locking. FreeBSD 11.4's `sys_munlockall` (`sys/vm/vm_mmap.c`:1133-1165) checks `priv_check(td, PRIV_VM_MUNLOCK)` first (returning `EPERM` without it) and unwires the user map (`vm_map_unwire` over `vm_map_min`...`vm_map_max` with `VM_MAP_WIRE_HOLESOK`). Returning 0 unconditionally assumes the calling process is privileged. `munlockall` unlocks memory locked by `mlock` (`VirtualUnlock` on Windows, tolerating `ERROR_NOT_LOCKED` for pages never locked, and `munlockall` on Linux). On main, XPSemu (PPSA97358) fails to load at these imports (mlockall #4386, munlockall); their calls in QEMU `os-posix.c` execute only when `-overcommit mem-lock=on` is enabled. The call has not been observed in a run with this implementation.
 - [sigtimedwait](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) waits on a process-wide pending set instead of throwing: a signal raised while blocked stays pending and is taken by `sigwait`, `sigwaitinfo` or `sigtimedwait`, delivered to the handler when `_sigprocmask` unblocks it, or delivered by `pause`. The set covers all 128 signals and the lowest number that is pending and in the set is selected (FreeBSD specifies the lowest number only among real-time signals). Selection, `EAGAIN` on timeout, `EINVAL` for a `tv_nsec` outside 0 to 1000000000 while nothing is pending and `NULL` timeout blocking indefinitely follow FreeBSD's [sigtimedwait(2)](https://man.freebsd.org/cgi/man.cgi?query=sigtimedwait). `sigwait` returns 0 with the number in its output, as POSIX specifies, and `sigwaitinfo` and `sigtimedwait` return the number, as FreeBSD does. The guest `siginfo_t` follows FreeBSD 11's `sys/sys/siginfo.h`: 80 bytes, `si_signo` at 0, `si_code` at 8, `si_pid` at 12, `si_uid` at 16, `si_addr` at 24, `si_value` at 32 and `si_band` at 40; only `si_signo`, `si_code` (`SI_USER`) and `si_pid` (the guest pid) are written, `si_uid` stays 0 because no uid is modelled, and the console's layout is not verified. PPSA85300 imports `sigtimedwait` and fails to load without it; its only call site is VLC's `vlc_writev` ([filesystem.c](https://github.com/videolan/vlc/blob/6de05adcbaf2e8b85fe86aad4169393098628119/src/posix/filesystem.c#L243-L278)), which polls with a zero timeout to drain a `SIGPIPE` only after `writev` fails with `EPIPE`. The waits are not cancellation points and an unblocked caught signal does not interrupt them with `EINTR`, where FreeBSD's `sigwaitinfo` and `sigtimedwait` may return it. `SIGPIPE` has no host equivalent and is never raised by a host write here (see `read, write and vector I/O`), so VLC's drain finds nothing
 - [pause, sigsuspend, sigwait, sigwaitinfo](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) take the pending set of `sigtimedwait` instead of throwing. `pause` waits for a pending signal that is not blocked and whose disposition can be delivered, runs its handler on the calling thread and returns -1 with `EINTR`; an ignored signal is discarded and the wait continues, and it never returns for a signal whose handler cannot run. A signal whose registered handler has `SA_SIGINFO` still throws, and one whose disposition is the default action and that has no host equivalent (every signal except 2, 4, 6, 8, 11 and 15) is neither delivered nor discarded: it stays pending until a wait takes it, where FreeBSD runs the default action, which terminates the process for most of them. PPSA68091, PPSA99169, PPSA99420 and PPSA97358 import them and fail to load without them. PPSA68091 calls `pause` at one site (0x8F7266), in a loop that waits while a global holds another thread's `errno` address. PPSA99169 only stores the address of `pause` in a table of symbol addresses (0x30DB1). PPSA99420 calls `pause` at 0x3BD80F6 and 0x3C9E220, `sigwait` at 0x3C9E4C7 and `sigwaitinfo` at 0x3C9E588. PPSA97358 calls `sigwait` from QEMU's `sigwait_compat` thread ([compatfd.c](https://github.com/ZiZc3/XPSemu/blob/8eec07b4e31f66dce8e0b05c1ca1281af303e933/util/compatfd.c#L28-L53)), which `qemu_signal_init` ([main-loop.c](https://github.com/ZiZc3/XPSemu/blob/8eec07b4e31f66dce8e0b05c1ca1281af303e933/util/main-loop.c#L110-L147)) starts for `SIGIO`, `SIGALRM` and `SIGBUS` when the main loop is created, so it reaches the wait at start-up, and from the vCPU thread of the dummy accelerator ([dummy-cpus.c](https://github.com/ZiZc3/XPSemu/blob/8eec07b4e31f66dce8e0b05c1ca1281af303e933/accel/dummy-cpus.c#L48-L56)). `sigsuspend` swaps the process-wide mask of `_sigprocmask` for its argument, waits as `pause` does through the same helper, then restores the mask through `_sigprocmask`, and returns -1 with `EINTR`; a null set throws, as the console faults in libthr instead of returning `EFAULT`. Like `_sigprocmask`, only the first 32 signals are blocked: words 1 to 3 of the argument are not applied, so signals 33 to 128 stay deliverable during the wait; widening the shared mask is a follow-up. Java 25 LAN / DNS (PPSA99869, #5501) imports it and fails to load without it, after `sysctlnametomib`, `fegetenv` and `mincore`. None of the five waits is a cancellation point
 - [getsid](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) returns the calling process ID for pid 0 and the calling process, and `ESRCH` for other process IDs, assuming the single guest process is its own session leader. PPSA74126 imports it and fails to load without it

Subject: [PATCH 0197/1000] test(libkernel): deny the kqueue parent listing to
 the token user's SID

DeniedParentWatch denied FILE_LIST_DIRECTORY to the name GetUserNameW
returns. When the user name equals the computer name, LookupAccountNameW
resolves that bare name to the computer's domain SID (SidTypeDomain), so
the deny entry matched no one, the parent watch was allowed and the test
aborted on an empty error. The entry now names the SID of the process
token's user.

Subject: [PATCH 0199/1000] fix(agc): read unregistered graphics programs
 beside registered shaders

Since 39fdc48b5 a graphics program outside every registered shader was
read raw only while the registry was empty, and any RegisterShader after
the first raw draw threw. A title that registers some shaders through
sceAgcCreateShader and also draws programs it never registers stops at
its first such draw with "graphics program does not belong to a
compatible registered shader": oops-sdk homebrew registers its display
shaders while radeonsi (oops-mesa) submits raw programs.

Graphics programs now resolve as compute dispatches already do: an
address inside a registered shader resolves to that registration (a
registration of another type still throws), any other address is read
raw. RegisterShader throws only when the new shader's code overlaps a
graphics program that was drawn raw, where the program would get a
second identity (the draw cache revalidates raw programs by reading them
raw), instead of after any raw draw.

The drawn range is recorded once per raw snapshot: a flag on the
snapshot keeps later decodes of the same program off the lock. Recorded
ranges are merged, so the overlap check looks only at the predecessor of
the queried end.

Tests: agc_driver_prepared_graphics (a draw whose programs are registered
as compute shaders is refused, where it used an address outside every
registration before), agc_driver (ProgramSnapshot reads raw beside registered shaders
and refuses a registered program of another type; nested, overlapping
and adjacent raw ranges), agc_driver_prepared_unregistered_graphics
(raw-drawn ranges recorded exactly, unrelated code not reported).

Subject: [PATCH 0202/1000] fix(agc): rasterize a multisampled depth target
 without MSAA_ENABLE at the pixel center

A draw with PA_SC_AA_CONFIG.MSAA_NUM_SAMPLES 2 (4x) and MSAA_ENABLE
clear into a 4x depth/stencil and color pair threw "multisampled
targets rasterized without MSAA_ENABLE are unsupported for points,
lines, a depth target or alpha-to-coverage", which stops METAL GEAR
SOLID: Peace Walker (PPSA18216) at its first presentation (draw B on
#5268). A depth target with the same sample count now gets the same
pixel center samples as the color targets, so each depth and stencil
sample is tested and written with the depth at the pixel center, as GL
allows when multisampling is disabled.

DB_EQAA Z interpolation or overrasterization and a sample-mask export
with a depth target throw on this path.

 - [GS_FAST_LAUNCH geometry](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - `VGT_SHADER_STAGES_EN.GS_FAST_LAUNCH = 1` with a point list and `GE_CNTL` groups of one vertex and one primitive decodes as one point per subgroup, with the primitive limit taken from `GE_NGG_SUBGRP_CNTL.PRIM_AMP_FACTOR` and the GS/ES VGPR counts not required. Follows how RADV drives mesh shaders on gfx10.3 (`ac_nir_lower_ngg.c`, the workgroup index comes from the vertex id of the first thread), not measured on the console. Fast launch 2, other group sizes or input primitives and indexed fast-launch draws still throw. PPSA03671's fast-launch draws decode, but the title stops earlier in a wave64 vertex program, so they have not reached the GPU yet.
 - [Alpha-to-coverage](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - only `DB_ALPHA_TO_MASK = 0xaa01` is accepted: the enable bit with the four quad offsets at 2 and no `OFFSET_ROUND`, the undithered setting [radeonsi](https://gitlab.freedesktop.org/mesa/mesa/-/blob/bffd91947efc1932da99aca69fc540d6d4201b0c/src/gallium/drivers/radeonsi/si_state.c#L371-L381) programs. Draws are single-sampled, so the pixel shader [writes](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) `SampleMask` 0 when its MRT0 alpha is below one half or NaN and all ones otherwise, and runs with late fragment tests. That rule was measured on a Radeon 660M (gfx1035, RADV with `RADV_DEBUG=noatocdithering`, which programs the same register) for 0, -0, 0.25, the two floats below one half, one half, the two above, 0.75, 1, 2, -1, both infinities and both NaNs, and is pinned in [AlphaToCoverage.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/AlphaToCoverage.cpp); it is not measured on gfx1013. Vulkan's `alphaToCoverageEnable` is not used: the NVIDIA driver 615.78.08 dithers single-sample coverage (an alpha of 0.25 writes half the pixels of an RTX 3050 Laptop target). Other offsets, `OFFSET_ROUND`, a sample-mask export, and an MRT0 that is missing, swizzled, packed or exported without a floating-point alpha throw. A draw without a color target on MRT0 keeps alpha-to-coverage from its MRT0 export, as [radeonsi exports MRT0 as `32_AR` for alpha-to-coverage without a color buffer](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-24.0.0/src/gallium/drivers/radeonsi/si_state_shaders.cpp#L2425-L2431). A draw that enables alpha-to-coverage with no MRT0 export still throws: what the console covers then is not measured. Default dithered `DB_ALPHA_TO_MASK = 0x18701` additionally uses a per-quad sample-mask table [measured on gfx1036](https://github.com/boykopovar/AnyPS5/pull/4451#issuecomment-6124848921) for eight standard samples with FP16_ABGR or 32_ABGR exports; other sample counts, custom locations, EQAA combinations and dithered UNORM16/SNORM16 exports throw. The dithered rule is not measured on gfx1013.

[RADV](https://gitlab.freedesktop.org/mesa/mesa/-/blob/745709a000482a4a24c91faef5c5a40bd653a863/src/amd/vulkan/radv_cmd_buffer.c#L13606-13609) programs this state for one-sample custom sample locations on GFX10 and later, where the bit makes the rasterizer use the programmed location of sample 0 ([061bc615](https://gitlab.freedesktop.org/mesa/mesa/-/commit/061bc6151a11597f720535f00e79a5752e24aff6)); that the bit changes nothing else for such a draw is inferred from that and is not measured on hardware.

A depth target with the same sample count also has every sample at the pixel center, so each depth and stencil sample is tested and written with the depth at the pixel center, as GL allows when multisampling is disabled ([L185-L190](https://github.com/KhronosGroup/OpenGL-Registry/blob/6af574a14089ccfee87efe230ebcdd8742859813/extensions/ARB/ARB_multisample.txt#L185-L190), [L422-L425](https://github.com/KhronosGroup/OpenGL-Registry/blob/6af574a14089ccfee87efe230ebcdd8742859813/extensions/ARB/ARB_multisample.txt#L422-L425)). GL also lets an implementation test only a centermost sample and set every sample from it ([L425-L434](https://github.com/KhronosGroup/OpenGL-Registry/blob/6af574a14089ccfee87efe230ebcdd8742859813/extensions/ARB/ARB_multisample.txt#L425-L434)), which differs when a pixel's stored samples differ; which one the console does, and how its occlusion queries count such a draw, is not measured on hardware. `DB_EQAA` Z interpolation or overrasterization and a sample-mask export with a depth target throw. Points, lines and alpha-to-coverage throw. SONIC SUPERSTARS (PPSA06888) draws such a 2x target, and METAL GEAR SOLID: Peace Walker (PPSA18216) a 4x depth and color pair.

Subject: [PATCH 0203/1000] fix(libSceAudioOut): check the audio buffer size
 for 32-bit overflow

prepareBuffer and queueAudio computed frames * channels * bytesPerSample
in 32-bit arithmetic. A large samplesNum from sceAudioOutOpen (which
only rejects len == 0) wraps the product, so buf.resize allocates a
truncated buffer while the mixing loops write frames * channels samples
past it. Compute the size in 64 bits and throw past INT32_MAX, which
also keeps the downstream int casts well-defined.

Subject: [PATCH 0204/1000] perf(shader): select the record of a T# whose
 offset the CPU evaluates

Since #757, a T# loaded from a buffer heap at a runtime offset is an
image table column, and every capture snapshots the whole heap, up to
65,536 records, even when user data or an SRT read fixes the offset.
When the T#'s eight dwords and its offset are runtime values the SRT
walker evaluates, the column is now selected: the offset is kept as a
descriptor source, the shader indexes entry 0, and the snapshot reads
only the record at the evaluated offset, with the heap base moved to
that record.

The column keeps a table's semantics. An invalid T#, an unmapped record
or an offset that carries past 32 bits is poison that faults only when a
lane selects it; an offset the walker cannot read faults the table
instead of throwing; the record's mode is picked per entry, so no
pipeline variant is added; and a dispatch that writes the record faults
it as written by its dispatch. Dwords past the heap read zeros, as the
scalar loads would, and a record past the key cap is read rather than
poisoned.

A column stays a whole table when its offset is chosen per lane, or when
the shader may write the memory the offset is read from at run time: the
buffer it is read from (by V#), or any memory when the read or a write
goes through a pointer or a GPU-only descriptor. Samplers are unchanged:
an S# the walker evaluates is already a direct sampler. The plan stores
the selection, so the disk cache format is 36.

Five agc_shader_memory and agc_shader_bindless checks asserted the old
planning and now assert the selected record:
- "image table SRT key": a key read through the SRT narrowed a 4-key
  table to records 0 and 2. It now selects record 2 alone, captures no
  other record, and a changed key moves the capture without changing the
  module or its disk key.
- "image table key union" and "image table late key": two keys of one
  heap shared one column with two value key domains. Each key now
  selects its own record, as two one-record tables.
- "image table unkeyed access": a read keyed through the SRT shared a
  whole column with a read keyed per lane. The first now selects its
  record; the second keeps the whole, unnarrowed table.
- "uniform table image": the T# at a user data offset was one key of a
  full table. It is now the one selected record, and the record the user
  data does not select is not read.
A value key domain only arises for a key the walker evaluates, so it no
longer narrows an image column; key buffer domains (keys loaded per
lane) still do.

 A T# or S# that a shader loads from a buffer at a runtime offset (`key * stride + addend`, or `(key << n) & mask`) is not a direct descriptor. [`ResourceTracker.cpp`](../../core/shader/recompiler/Optimization/src/ResourceTracker.cpp) plans it as a table column (`TableColumn`): the heap V#'s descriptor source, the record stride and addend, the descriptor's offset in the record, and the key domains that may narrow it. Accesses with the same heap and record shape share one column. The shader keeps computing the offset and indexes a table binding: images use one variable-count `SAMPLED_IMAGE` array (`RuntimeAbi::ImageTableBinding`, in the fragment set when pipeline libraries split the sets), samplers a `SAMPLER` array (`Binding::SamplerTable`). Devices without `runtimeDescriptorArray`, `descriptorBindingPartiallyBound` and `descriptorBindingVariableDescriptorCount` refuse such shaders.
 
-At every invocation, `TableSnapshotter` in [`ResourceMaterializer.cpp`](../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) reads each column's records from guest memory into `ResourceSnapshot::tables`: heap base and size, the record count (at most `ImageTableAbi::MaxKeys`), one code per record (an index into the distinct descriptor words, or a poison code) and the ranges it read. A column narrows to the records its keys select, plus record 0, when every access has a key domain: a value the SRT walker evaluates from user data, SRT reads and constants, or a key buffer of at most 256 positions (`APS5_IMAGE_TABLE_KEY_SCAN`). A loop-carried, lane-reduced or masked key keeps the whole column, so the cost of an invocation grows with the column's records and its distinct T#s. The snapshot is part of the invocation, not of the compiled variant: a changed table changes neither the SPIR-V nor the variant's disk key.
+A T# whose eight dwords and record offset the SRT walker can evaluate is planned as a selected column (`TableColumn::selected`): the offset is kept as a descriptor source (`TableColumn::selection`) and the shader indexes entry 0 of a one-record table. The column stays a whole table when the shader may write the memory its offset is read from at run time: the buffer it is read from, or any memory when the read or a write goes through a pointer or a GPU-only descriptor. Samplers are not selected: an S# the walker can evaluate is a direct sampler.

+At every invocation, `TableSnapshotter` in [`ResourceMaterializer.cpp`](../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) reads each column's records from guest memory into `ResourceSnapshot::tables`: heap base and size, the record count (at most `ImageTableAbi::MaxKeys`), one code per record (an index into the distinct descriptor words, or a poison code) and the ranges it read. A selected column evaluates its offset and reads only that record, as the scalar loads would: dwords past the heap read zeros, an unmapped record or an offset that carries past 32 bits is poison, and an offset the walker cannot read faults the table instead of throwing. Its heap base moves to the record, so the shader's fault address and the written-heap check cover that record alone. Any other column narrows to the records its keys select, plus record 0, when every access has a key domain: a key buffer of at most 256 positions (`APS5_IMAGE_TABLE_KEY_SCAN`), or a value the SRT walker evaluates from user data, SRT reads and constants (which, for an image, selects its record before it could narrow). A loop-carried, lane-reduced or masked key keeps the whole column, so the cost of an invocation grows with the column's records and its distinct T#s. The snapshot is part of the invocation, not of the compiled variant: a changed table or key changes neither the SPIR-V nor the variant's disk key.
 
 `ResolveImageTables` turns the snapshot into the map buffer (`DescriptorRole::ImageTableMap`, layout in [`ImageTableAbi.hpp`](../../core/shader/recompiler/ImageTableAbi.hpp)): a header, eight words per table (map start, key count, heap base and size, the code for keys past the snapshot, a table fault) and one record per key (flags with the decode mode, the swizzle dword and the element for images; flags and element for samplers). The shader reads `map[key]` and switches over the image's prepared runtime modes. Each distinct T# becomes one element, up to `ImageElementBudget` and the device's capacity. An entry that does not decode, is multisampled or over budget, pairs a reducing sampler with a point-only mode, is an unnormalized or reducing S#, or whose surface has no mapped byte is poisoned: it reads zeros and reports a fault through the BDA fault buffer only when a lane selects it (`APS5_IMAGE_TABLE_STRICT=1` throws at the snapshot instead). The driver's `resolveImageTables` in [`ShaderResources.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) looks up or creates a texture per element and keeps the last four resolved tables per thread for reuse within one collect epoch while their memory is unchanged. Cached objects grow with their tables, so the resource cache keeps at most `ResourceCache::TableElementBudget()` table elements (65,536, `APS5_RESOURCE_CACHE_TABLE_ELEMENTS`) and evicts its least recently used table objects past that, and the dispatch cache evicts its least recently used entries while their captured words exceed `Driver::DispatchCacheBytes()` (256 MiB, `APS5_DISPATCH_CACHE_BYTES`).

At dispatch the callee is read from guest memory up to its `s_setpc_b64` on the link pair, one copy of it is appended per call after the caller's last instruction, and the call is rewritten to `s_call_b64` to that copy. The words after the caller's last instruction are dropped from the recompiled code; in the shaders seen they are metadata or constants the caller reads relative to its program counter, and those reads go to the captured guest code, which linking does not change. A caller that jumps through a table among those words, which the control flow analysis reads from the recompiled code, throws. A copy runs at another program counter than the callee, so a callee that reads its program counter, makes a call, ends the program, jumps through another pair, returns before code it branches to, spans more than 64 KiB or is not readable throws. Callees are read again whenever a dispatch misses the dispatch cache; a dispatch that hits it reuses the linked program, so a title that rewrote a callee in place at the same address would keep running the old code.
 - [Table callees](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Shaders/ShaderRegistry.cpp) (libSceAgcDriver) - a compute shader's `s_swappc_b64` whose source pair is two consecutive dwords of an `s_buffer_load_dword*`, or a copy of them made with `s_mov_b32` or `s_mov_b64` in the same block, calls one of the targets that buffer holds when the load's buffer descriptor comes from an `s_load_dwordx4` without SOFFSET from a user-data pointer and the load's SOFFSET from an `s_lshl_b32` by 2 to 24 bits. At dispatch the descriptor and the buffer are read from guest memory, and every non-zero 64-bit value at the loaded offset plus a multiple of the shift's stride, below the descriptor's size (stride times num_records, or num_records bytes with stride 0), is read as a user-data callee and appended once per call. The call becomes a branch to a chain that compares the source pair with each target (`s_cmp_lg_u32` with a literal and `s_cbranch_scc1` per dword) and `s_call_b64`s the copy that matches; no match runs the original `s_swappc_b64` as an unlinked call. There is one chain for each value SCC has at the call, and the chain sets SCC back to that value (`s_cmp_eq_u32 0, 0` or `s_cmp_lg_u32 0, 0`) before the callee or the unlinked call runs. The searched range is the descriptor's whole size, which covers the range the load can reach whether it is checked in bytes or in strides; which one the PS5 uses for `s_buffer_load` was not measured. More than 64 distinct targets, a buffer above 64 MiB or a copy out of `s_call_b64` range throws. As with user-data callees, the buffer is read again only when a dispatch misses the dispatch cache, so a target a title adds to the buffer later is an unlinked call when a cached program runs.

Subject: [PATCH 0205/1000] feat(shader): name why image table narrowing is
 skipped

The [image-table] line under APS5_PROFILE_DRAW now splits the skipped
narrowings by reason: a value key that cannot be evaluated, a key
descriptor that is not a buffer, a key buffer with more positions than
APS5_IMAGE_TABLE_KEY_SCAN (with the most positions seen), pending GPU
writes over the key buffer, and an unmapped key page. Selected records
never narrow, so the line counts them apart.

Subject: [PATCH 0206/1000] fix(agc): copy an indirect draw's vertex buffer
 only up to its last element

For an indirect draw, whose counts only the GPU knows, the driver copies
the whole range a vertex buffer descriptor covers, records * stride from
the descriptor's address. The last record's element ends sooner when the
attribute sits at an offset in its record, and the fetch can read at most
(records - 1) * stride plus the element.

Forspoken (PPSA03984) draws instances from a 48 MiB buffer of 96-byte
records with six attributes at offsets 0 to 0x50 in each record. The copy
for the attribute at 0x50 ran 0x50 bytes past the buffer into the
unmapped page after it, and the draw stopped with "guest memory is not
readable".

VertexBufferExtent now ends at the last record's element, as
VertexBufferReadSize does for the last record of a direct draw.

Subject: [PATCH 0207/1000] docs(debt): describe the narrowed vector window and
 its measurement

The relative vector addressing entry still said every window register
lives in one function-scope array. It now describes the array of the
bounded slots, the per-slot variables, the OpSwitch fallback and
APS5_NO_WINDOW_NARROWING, with the RTX 3060 measurement.

 - [EmitSetAttribute](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - a primitive with a vertex whose clip position is (0,0,0,0) is clipped away through an extra `gl_ClipDistance` element on vertex and tessellation evaluation shaders, matching what a Radeon 610M (RDNA2, RADV) and llvmpipe rasterise; NVIDIA 615.78.08 without it draws the vertex at the viewport centre. Measured for triangles (strip and list) and for a point at (0,0,0,0), which the Radeon 610M does not draw, NVIDIA draws at the viewport centre and llvmpipe at the top-left corner; lines with such a vertex are clipped by the same element and were not measured. Mesh, geometry and the generated rect-list and barycentric stages do not write it, a device without `shaderClipDistance` cannot compile vertex shaders (the compile throws), and guest clip distances are still refused by the pipeline validator. The PS5 rasteriser was not measured.
 - [LINE_STIPPLE_TEX](../../../core/shader/recompiler/Translation/src/InstructionTranslator.cpp) (recompiler) reads as 0: line stipple is not emulated. RADV enables the input only as the required pixel input of a shader that reads no interpolants, because it initializes the fewest VGPRs ([Mesa](https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/amd/vulkan/radv_shader.c) `radv_compute_spi_ps_input`), and never reads it
 - [Static scalar calls](../../../core/shader/recompiler/ControlFlow/src/GraphBuilder.cpp) (`s_call_b64` and `s_swappc_b64`) require an ordinary even-aligned SGPR link pair (s0:s1 through s104:s105) and a later `s_setpc_b64` return reading that exact pair. A pair serves one call, or several calls whose regions are disjoint, each closed by the first return reading the pair after its target. Outside every region of its calls the pair may only be overwritten whole, by `s_mov_b32`, `s_mov_b64`, an SOP2 result or a scalar load, as the caller of a user-data callee does before each call. Regions must nest or be disjoint; recursion, other shared links, escaping link values (including overlapping tuples and resource descriptors), invalid targets, interleaved regions, cross-region branches or fall-through, relative SGPR reads and dynamic `s_setpc_b64` in a program with calls throw. The analysis checks all decoded instructions, including unreachable code. Arbitrary indirect calls and general call frames are not implemented.
-- [Relative vector addressing](../../../core/shader/recompiler/Translation/src/ControlFlowInstructions.cpp) (`v_movrels_b32`, `v_movreld_b32`, `v_movrelsd_b32`, `v_movrelsd_2_b32`, `v_swaprel_b32`) keeps every vector register from the lowest base register the program addresses relatively up to the last register the program names in a zero-initialised function-scope array per invocation (`LoadVectorWindow`/`StoreVectorWindow`, one element per register), so an indexed access is one load or store instead of a compare-and-select chain over the window; the host compiler decides whether that array stays in registers or spills to scratch, which is not measured. A register in the window the program never wrote reads 0, as an unwritten SSA register does; the console's value is undefined. M0 is unsigned: an index at or past the window reads `v0` and drops its write, and `v_swaprel_b32` writes neither side when either is out of range, as measured on RDNA2 (gfx1035, `agc_driver_relative_indexing`). The window ends at the last register the program names rather than at the shader's VGPR allocation, which the recompiler does not receive, so a relative write past the named registers but inside the allocation is dropped where the hardware keeps it for a later relative read. Killzone: Liberation's PSP vertex program (PPSA11142, 3176 ISA words, 104 relative accesses over 154 registers) went from 649,515 to 392,333 SPIR-V words with this. Pixel programs whose relative span contains the packed ancillary input instead keep that span in SSA and implement indexed operations with compare/select chains. This keeps ancillary definitions visible to field lowering and masked-write proofs; storing the unmodelled whole word in a private array would require composing unknown bits. A fold after masked-select elimination lowers fields whose consumers become visible only after redundant copies are removed. A whole-word use that the masked-select pass keeps gets the composed word described under the packed pixel ancillary word. Both representations include implicit entry inputs in the inferred register limit and retain unsigned M0, inactive-write and DPP update rules; wave32/wave64 native Vulkan readbacks cover relative reads, writes, split-offset swaps, inactive writes, DPP masks and out-of-range accesses, but console comparison and the performance cost of selecting over this span are unverified.

[`IndexedWindowSlots`](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvModuleSetup.cpp) bounds each relative index through the IR (bit-field extracts, masks, shifts, adds, selects, phis, `ReadFirstLane` and the window stores that reach a load); the storage is an array of the slots below the largest bound that is under half the window, and one function variable per slot after it. A constant index uses the array element or the slot's variable; a relative access whose index has no such bound, or lands past the array at run time, indexes the array below its size and otherwise branches through an `OpSwitch` over the slot variables, so the bound only decides speed. When no index has a bound under half the window, the whole window is the array, as with `APS5_NO_WINDOW_NARROWING=1` (a recompiler switch in the shader cache key). Measured on an NVIDIA GeForce RTX 3060 (driver 615.78.08, Linux) with a compute program whose 167-register window an ALU loop reads and writes in full and whose relative accesses take `m0 = s8 & 3`: a 2048-group dispatch took 70.2 ms in wave32 and 123.3 ms in wave64 with the whole window in the array (as before narrowing) and 1.9-2.1 ms and 7.8 ms narrowed; with a second relative access whose index has no bound and lands past the array at run time (index 50 or 166), 113 ms and 5.8-6.0 ms in wave32. In the PPSA08427 (Killing Floor 3) hub it made no measurable difference to presents or to the GPU time of the eight most expensive programs. Whether the host compiler keeps the array and the slot variables in registers or spills them to scratch is not measured. A register in the window the program never wrote reads 0, as an unwritten SSA register does; the console's value is undefined. M0 is unsigned: an index at or past the window reads `v0` and drops its write, and `v_swaprel_b32` writes neither side when either is out of range, as measured on RDNA2 (gfx1035, `agc_driver_relative_indexing`).

 - [s_call_b64](../../../core/shader/recompiler/Translation/src/ScalarInstructions.cpp) saves `PC + 4` over `GetShaderBase` and branches to `PC + 4 + signext(SIMM16) * 4`, following [AMD RDNA2 ISA](https://gpuopen.com/download/rdna2-shader-instruction-set-architecture.pdf) sections 3.6.3, 12.2 and 12.3. Forward callees after `s_endpgm` are decoded. Measured on RDNA2 (gfx1036) in wave32 and wave64 with SIMM16 = 3: the link pair receives `PC + 4`, the branch goes to `PC + 4 + signext(SIMM16) * 4`, and `s_setpc_b64` of the link returns to the instruction after the call. Execution on the PS5 (gfx1013) and title compatibility for these bounded scalar calls remain unverified; `s_rfe_b64` still throws in translation.
 - [BDA span reads](../../../core/shader/recompiler/SpirvBackend/src/SpirvBdaRead.cpp) (shader recompiler) - `read_bda_span` is one selection: one arm calls `load_bda_span`, a `DontInline` function that holds the in-place dword loads and calls nothing, and the other arm is the per-dword byte fallback. Two other shapes of the same reads each hang a group of NVIDIA drivers, where a dispatch never finishes and the device is lost. With the loads emitted in the arm itself, a dispatch whose lanes took both arms hung on an RTX 3060 and an RTX 4060 Laptop GPU (Windows, driver 591.86) and an RTX 5060 (Linux, driver 590.48.01) ([#3291](https://github.com/boykopovar/AnyPS5/issues/3291)). With the loads and the fallback as two selections, the first under the span's condition and the second under its negation, it hung on an RTX 4070 Laptop GPU (Windows, drivers 595.97 and 596.36), an RTX 5080 (Windows, driver 610.62) and an RTX 4090 (Linux, driver 610.57.04) ([#4975](https://github.com/boykopovar/AnyPS5/issues/4975)). The current shape is measured on the RTX 4090 with driver 610.57.04 only, where it does not hang with or without SPIRV-Tools; a shape with the loads in their own `DontInline` function was reported passing on driver 591.86 in #3291. The cause inside the driver is not known.
 - [SDWA source selects on `v_cvt_f32_ubyte1`, `v_cvt_f32_ubyte2` and `v_cvt_f32_ubyte3`](../../../core/shader/recompiler/RdnaDecoder/src/RdnaVectorOpDecoder.cpp) (shader recompiler) - byte N is taken from source 0 after `SRC0_SEL` and `SRC0_SEXT` select and extend it, since SDWA supplies source 0 (RDNA 2 ISA guide 6.8 and 13.3.7) and the opcode reads `S0.u[8N+7:8N]` (12.8). Not measured on hardware.

Subject: [PATCH 0208/1000] test(shader): cover selected image table records
 and their fallbacks

agc_shader_memory and agc_shader_bindless: an invalid selected T# is
poisoned with its words without changing the artifact; a key past the
heap selects a null image without reading the heap; an unmapped selected
record is Unmapped poison and is not read; a key loaded from a constant
buffer at an SRT offset selects its record, and one that cannot be read
faults the table instead of throwing; a key loaded from a buffer the
shader writes keeps the whole table; a key chosen per lane keeps the
table; a record past the 65,536-key cap is selected; and a selected
record whose second load carries past 32 bits is OffsetCarry poison while
the record past the wrap is read.

agc_driver_image_table: a dispatch keyed from a constant buffer at an SRT
offset samples three records exactly as their direct bindings do, with
one module and one bound image; samples zeros for a key past the table;
does not fault for an invalid record under a clear EXEC; reports the
invalid record's address, words and reason when it selects it; and faults
when it stores over its selected record.

agc_shader_disk_cache: a selected column round-trips in the hand-built
plan, a fixture plans one and materializes it after a round trip, and a
selection past the sources is rejected.

Subject: [PATCH 0209/1000] fix(libSceNetCtl): answer the DHCP host name, PPPoE
 name and proxy server as empty strings

Since #5056, sceNetCtlGetInfo throws for every info code it does not
model. Ghost of Yotei (PPSA26344) asks for code 12, the DHCP host name,
during boot and now aborts one second in.

The configuration #5056 reports (wired, DHCP, HTTP proxy off) sets no
DHCP host name, no PPPoE user name and no proxy server, so codes 12, 13
and 20 now return 0 with an empty string. The Wi-Fi codes (5-10) and
the proxy port (21) still throw. GuestNetCtl checks the three empty
answers and keeps the throw check for the rest; the libSceNetCtl debt
line says the same.

 - [gethostname](../../../core/libs/prx/libc/src/Hostname.cpp) (libc) reports the fixed guest name `AnyPS5` without querying the host machine name. Buffer copying, null queries and `ENAMETOOLONG` follow [FreeBSD gethostname](https://github.com/freebsd/freebsd-src/blob/main/lib/libc/gen/gethostname.c); the console's configurable hostname and its integration with `sysctl` and name resolution are unverified and not implemented.
 - [wcsrtombs_s](../../../core/libs/prx/libc/src/Multibyte.cpp) (libc) follows the console's `libc.prx`, but a runtime-constraint violation only returns its error: the default handler there writes the message and a newline to `stderr` before returning, which is not done here. Conversion uses the C locale of `wcrtomb` (`MB_CUR_MAX` 1), so the path where a multibyte character does not fit the remaining space is not reached
 - [The narrow printf family](../../../core/libs/prx/libc/src/Formatting.cpp) (libc) converts 16-bit guest wide arguments to UTF-8 on both platforms, independently of the host locale. It does not use the guest's single-byte `wcrtomb`; the console's treatment of invalid UTF-16 and locale-specific encoding remains unverified. Linux retains host formatting for formats without wide arguments or `%m`, so a narrow `%p` and a NaN there still follow the host (glibc prints a null pointer as `(nil)`, where FreeBSD prints `0x0`, and a NaN with its sign, `-nan`, and with the `+` and space flags, where FreeBSD prints `nan`); argument positions above 99 (FreeBSD's `NL_ARGMAX`) throw when a format requires the guest formatter
-- [collate<char> and collate<wchar_t> _Getcat](../../../core/libs/prx/libc/src/LocaleSupport.cpp) (libc) build the facet for the C locale only and throw for any other locale name, the wide entry point following the narrow one it sits next to. The wide facet carries the narrow vtable because [GuestLocale](../../../core/libs/prx/libc/include/GuestLocale.hpp) models one facet layout and one vtable for both element types, so a `collate<wchar_t>` comparison, transform or hash runs the narrow `do_compare`, `do_transform` and `do_hash` over the guest's 16-bit characters read as bytes; the console's `libc.prx` exports both `_Getcat` (NIDs BSVJqITGCyI and 2wz4rthdiy8) with identical 0x19d-byte bodies, believed to build the same 0x20-byte facet; the console bodies themselves are unreadable (obfuscated dynsym), the wide vtable is not reproduced here and no console run checks the two. The console's `libc.prx` stores pointers to its collation state tables at offsets 0x10 and 0x18 of the facet; ours leaves them null, as only the facet's own functions read them. `do_transform` throws for input with embedded null characters, which the console drops depending on the output buffer size. Its result capacity (`length | 15`) and the over-aligned storage of results of 4080 characters or more follow the console's `libc.prx` code and are not checked on hardware. No module of the PPSA59322, PPSA76677 or PPSA97358 dumps in this tree imports either `_Getcat`, so neither has been exercised by a title.
+- [collate<char> and collate<wchar_t> _Getcat](../../../core/libs/prx/libc/src/LocaleSupport.cpp) (libc) build the facet for the C locale only and throw for any other locale name, the wide entry point following the narrow one it sits next to. The wide facet carries its own vtable, whose `compare`, `transform` and `hash` take the guest's 16-bit characters, so the length of a range is a count of characters: `compare` orders by 16-bit value (the C locale, as Dinkumware's `char_traits<wchar_t>::compare` does), `transform` copies the characters into the result as the guest's bytes and sizes the result in bytes (two per character, a 16-bit terminator, the 7 characters that still fit next to it and `length * 2 | 15` plus two bytes of storage beyond that), and `hash` mixes one whole character per round, so wide text below 0x100 hashes like its narrow spelling and a character above 0xff hashes as one value instead of the two bytes it holds. The console's `libc.prx` exports both `_Getcat` (NIDs BSVJqITGCyI and 2wz4rthdiy8) with identical 0x19d-byte bodies, believed to build the same 0x20-byte facet; the console bodies themselves are unreadable (obfuscated dynsym, and the text of the relinked `libc.prx` is zeroed), so the wide entries follow the narrow algorithm and the C locale instead of the console's wide code, and no console run checks the two. The console's `libc.prx` stores pointers to its collation state tables at offsets 0x10 and 0x18 of the facet; ours leaves them null, as only the facet's own functions read them. `do_transform` throws for input with embedded null characters, which the console drops depending on the output buffer size.

 - [The scanf family](../../../core/libs/prx/libc/src/Formatting.cpp) (libc), the `_s` forms included, on Linux throws for the 16-bit wide conversions (`%ls`, `%lc`, `%l[`, `%S`, `%C`): glibc would store a 32-bit `wchar_t` per character into the guest's 16-bit buffer. Windows hands `%ls`, `%lc` and `%l[` to the host, whose `wchar_t` is 16 bits
 - [The scanf family](../../../core/libs/prx/libc/include/WindowsScanning.hpp) (libc) on Windows returns 0, as C17 and FreeBSD do, when input fails after only suppressed conversions have completed (`sscanf("12", "%*d%d", &value)`). Linux hands the format to glibc, which returns `EOF` there. On Windows the host stops a `%x`, `%X`, `%i` or `%p` after the `x` of a `0x` that no hex digit follows (or that the width cuts off), and a float conversion (`%e`, `%f`, `%g`, `%a`) after the `e` of an exponent with no digits (`1e`), where C17 and FreeBSD stop before the `x` or the `e`
 - [Guest path resolution](../../../core/libs/prx/libc/src/General.cpp) falls back to ASCII case-insensitive component lookup, following [shadPS4's host filesystem](https://github.com/shadps4-emu/shadPS4/blob/945dbc3cc3eee80ac3e053b438502ed936fa6bb2/src/core/file_sys/backends/host_fs.cpp). PPSA03747 requests `Skyrim.INI`, `Data/Video` and lowercase archive/plugin names that differ from the dump's filenames. Exact host names take precedence; multiple fallback matches throw instead of selecting an arbitrary file. Existing parent names are resolved when creating a new file, and guest mount aliases use the same ASCII comparison. Results are not cached, so renames and newly created files remain visible. Unicode case folding and PS5 behaviour for case-colliding host entries are unverified; host roots are used as supplied. Explicit native Windows drive and UNC paths bypass guest parent-component validation.. A relinked module's `<name>.guest.prx` is matched the same way when the original module is not beside it: Borderlands 4 (PPSA01494) loads `/app0/prx/libRenoirCore.PS5.prx`, which it ships as `librenoircore.ps5.prx`

Subject: [PATCH 0216/1000] refactor(agc): keep the private heap lookup and
 expose a public wrapper

LargestDeviceLocalHeap now calls ShaderResources.cpp's private
largestDeviceLocalHeap instead of replacing it, so the file's callers
stay as they are on main and other changes that call the private helper
still build with this one.

 - [sceNpGetSandboxInfo](../../../core/libs/prx/libSceNpManager/Export.cpp) (libSceNpManager, NID `ZVZ++68nNI8`) - the name hashes to the imported NID (found with nidhunt, confirmed with `tools/nid_names.py`). STAR WARS: Galactic Racer (PPSA28416) imports it; its OnlineSubsystemPS5 calls it with one pointer to a 0x50-byte stack buffer and reads the buffer as a string (discussions/3086). The returned string, the exact parameter struct and console errors are unknown, so every call throws without reading or writing caller memory. A working implementation belongs with that title's bring-up.
 - [sceNpSetTimeout](../../../core/libs/prx/libSceNpManager/Export.cpp) (libSceNpManager) - the signature follows [orbital](https://github.com/AlexAltea/orbital/blob/b321fcdbd700cc02da1cb1ad25412781d5ec73c6/tools/ida/db_types.json), [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/0fe263a4760dfbfa973366890061749b4af0de97/src/core/libraries/np/np_manager.cpp) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Np/NpAccount.cs); the rejected values (all five 0, negative retries, a resolve timeout under 1 s or another timeout under 10 s, 0 meaning the default) are shadPS4's, not checked on a console. An id that was never created or was deleted returns `REQUEST_NOT_FOUND`, as in shadPS4; there is no network, so the timeouts are not stored
+- [sceNpGetUserIdByAccountId](../../../core/libs/prx/libSceNpManager/Export.cpp) - the `(account id, user id output)` signature and its errors follow [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/np/np_manager.cpp): account id 0 or a null output returns `SCE_NP_ERROR_INVALID_ARGUMENT`, and a signed-out NP returns `SCE_NP_ERROR_SIGNED_OUT` without writing the output. NP is always signed out here, so no account id resolves to a user

Subject: [PATCH 0220/1000] feat(libkernel): implement kevent EV_DISABLE,
 EV_DISPATCH and EV_FORCEONESHOT

A knote registered or modified with EV_DISABLE stays registered but is
not polled, fired or reported until an EV_ENABLE change re-arms it, as
kern_event.c does with KN_DISABLED. EV_DISPATCH reports an event once
and then disables the knote, and EV_FORCEONESHOT registers as oneshot.
A negative nevents fails with EINVAL instead of throwing.

Every part is checked for a GPU or image pin before the first one is protected; the parts are then protected one after the other, so a host protection failure in a later part leaves the earlier parts changed (FreeBSD's `vm_map_protect` cannot fail in its second pass). The behaviour on the console is not known. None of this was measured on a console.
 - [JIT shared memory](../../../core/libs/prx/libkernel/DirectMemory/Jit.cpp) (libkernel) - `sceKernelJitCreateSharedMemory`, `sceKernelJitCreateAliasOfSharedMemory` and `sceKernelJitMapSharedMemory` take the signatures of [Orbital](https://github.com/AlexAltea/orbital)'s `tools/ida/db_types.json` (name, length, maximum protection, descriptor out; descriptor, maximum protection, descriptor out; descriptor, protection, address in and out), which ps4sdk, ps5-jar-loader and the call sites in RetroArch PPSA99169, XPSemu PPSA97358 and VLC PPSA85300 match; SharpProspero declares the alias as returning the descriptor. The object is a host anonymous file shared by its descriptors (a `memfd` on Linux, a delete-on-close temporary file mapped as an executable section on Windows), the alias is a duplicate descriptor, and every map maps the whole object, so writes through one view show through the others; a non-null address is a hint, as in `mmap` without `MAP_FIXED`. Not measured on the console: a length that is zero or not a multiple of 16 KiB and protection bits other than CPU read, write and execute are `EINVAL`; an alias or a map asking for more than the descriptor's maximum protection (write and execute counting as read) is `EACCES`, as FreeBSD 11's `vm_map_protect` treats a protection past `max_protection`; a descriptor that is not a JIT object is `EBADF`. The name is ignored, the objects do not count against the flexible memory budget, `mprotect` of a view is not limited to the maximum protection, and `mmap` of the descriptors is unsupported, as for `shm_open`. On Linux the `memfd` is created without `MFD_EXEC`, which Linux 6.3 added and older kernels reject with `EINVAL`, and relies on the protection of the mapping: the flag only sets the file's execute permission bits, and the direct memory `memfd` is mapped executable the same way; a host with `vm.memfd_noexec` set to 2 refuses the creation and the call throws

A new user event keeps its `fflags` unmasked and is not triggered by `NOTE_TRIGGER`, because `filt_userattach` reads the already cleared `kn_fflags`. The timer limit `kq_calloutmax` (`ENOMEM`) is not enforced, and closing a kqueue wakes a thread waiting on it in `kevent` with `EBADF`, where `kqueue_drain` makes the close wait for that thread. A level-triggered event is reported once per call and moved behind the other events, as in `kqueue_scan`; the `sceKernel*Equeue` calls keep their own collection loop

FreeBSD's hints depend on the filesystem and the console's filesystems are not known: a growing `ftruncate` reports `NOTE_WRITE | NOTE_EXTEND` where `vop_setattr_post` reports `NOTE_ATTRIB`, and on Windows `utimes` on a file reports `NOTE_WRITE`. The three Windows notifications are told apart in the error, which names the `parent`, `entries` or `subdirectories` watch, the path it was given and `GetLastError`, but a `FindFirstChangeNotification` that fails still throws rather than returning an error to the guest: the EVFILT_VNODE attach path is [`vfs_kqfilter`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L4936), which returns `EINVAL`, `ENOMEM` or 0 after `fget` has turned a descriptor that is not open into `EBADF`, and consults no directory permission, so no FreeBSD errno stands for a host that refuses to notify, and what the console does on such a host is not measured. Only the `parent` watch can fail this way in practice: `entries` and `subdirectories` need the `FILE_LIST_DIRECTORY` that opening the watched directory already took. The parent handle produces no hint of its own, as `RunHostWatch` only calls `FindNextChangeNotification` on it, so a later change may leave the watch on its 50 ms poll instead of throwing; that is not done here. Windows uses `FindFirstChangeNotification` on the parent directory (and on a watched directory itself) and compares `GetFileInformationByHandleEx` snapshots at least every 50 ms, because a write through an open handle is reported only when the handle is flushed or closed, so file hints can arrive 50 ms late, and a file deleted while watched, which the POSIX delete of Windows 10 1903 moves into `$Extend\$Deleted` until its last handle closes, reports `NOTE_DELETE` without `NOTE_RENAME` and keeps its handle without a parent directory watch, as that directory cannot be watched; Linux uses inotify on the file and is not run. `NOTE_REVOKE`, `NOTE_OPEN`, `NOTE_CLOSE`, `NOTE_CLOSE_WRITE`, `NOTE_READ`, unknown bits and descriptors other than files, directories, pipes and sockets throw. `sceKernelAddFileEvent(eq, fd, watch, udata)` and `sceKernelDeleteFileEvent(eq, fd)` take the [OpenOrbis](https://github.com/OpenOrbis/OpenOrbis-PS4-Toolchain/blob/0a1aaf9d/include/orbis/libkernel.h#L35) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0/src/SharpProspero/Interop/Kernel/KernelEqueue.cs#L164) signatures; `watch` is taken as the `fflags` and the event is added with `EV_CLEAR`, neither confirmed on a title

 - [sem_timedwait](../../../core/libs/prx/libkernel/Pthread/Posix/Sem.cpp) (libkernel) consumes an available count before checking the timeout and waits indefinitely for a null timeout, following FreeBSD 11's `sem_timedwait`. Console behavior for null and invalid timeouts when a count is available is unverified.
 - [tcsendbreak, tcdrain, tcflush, tcflow, tcgetpgrp, tcsetpgrp](../../../core/libs/prx/libkernel/File/src/Terminal.cpp) (libkernel) follow FreeBSD 11.4's [`termios.c`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/gen/termios.c): `tcflush` answers `EINVAL` for a queue other than `TCIFLUSH`, `TCOFLUSH` or `TCIOFLUSH` and `tcflow` for an action outside `TCOOFF`..`TCION` before the descriptor is looked at, and every other call fails as its terminal ioctl does on a descriptor that is not a terminal, with the errors `tcgetattr` gives, so `tcsendbreak` never reaches its 0.4 s pause. FreeBSD's `pipe_ioctl` answers `TIOCGPGRP` and `TIOCSPGRP` on a pipe or FIFO with the descriptor's SIGIO owner, which is not modelled, so `tcgetpgrp` and `tcsetpgrp` throw on a host pipe or FIFO above descriptor 2; descriptors 0 to 2 are taken as non-terminals that are not pipes, whatever the host attaches to them, so a pipe the guest creates on a freed descriptor 0 to 2 gets `ENOTTY` there. The PS5 `libkernel` is assumed to use this FreeBSD code, and `tcdrain` is not a cancellation point here
 - [Windows file timestamps](../../../core/libs/prx/libkernel/File/include/WindowsFileTime.hpp) use the host filesystem's timestamp range and resolution. `utimes`, `futimes`, and `lutimes` reject timestamps outside nonnegative signed 64-bit Windows file-time ticks with `EINVAL`, including exactly 1601-01-01 00:00:00 UTC, whose zero value means "leave unchanged" to `SetFileTime`. Guest directory descriptors still resolve through their recorded path. Filesystems with coarser timestamp resolution cannot retain every guest microsecond

Subject: [PATCH 0221/1000] fix(libkernel): follow kqueue_register for
 EV_FORCEONESHOT and modify flags

On a new knote EV_FORCEONESHOT is dropped from the flags; on an
existing one it sets EV_ONESHOT and fires the knote, as
kqueue_register does at l.1339-1341. A modify no longer ORs
EV_ONESHOT, EV_CLEAR or EV_DISPATCH into the knote.

-- [EVFILT_VNODE, sceKernelAddFileEvent and sceKernelDeleteFileEvent](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) (libkernel) watch the host file or directory behind the descriptor and turn host changes into FreeBSD 11 vnode hints, which [`filt_vfsvnode`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L5032) adds whole when they share a bit with the requested `fflags`: a write that grows a file is `NOTE_WRITE | NOTE_EXTEND`, another write `NOTE_WRITE`, a shrinking truncate or an attribute change `NOTE_ATTRIB`, a higher link count `NOTE_LINK`, a lower one or a pending delete `NOTE_DELETE`, a new path `NOTE_RENAME`; in a directory, an entry created, removed or renamed is `NOTE_WRITE`, with `NOTE_LINK` for a subdirectory, and on Linux an entry moved from or to another directory adds `NOTE_EXTEND`; inotify queues the two halves of a rename one after the other, so a watcher woken by the first can read it alone, and a half read without the other is classified only after a `getdents64` on the watched directory, which takes the directory lock that `rename` holds until both halves are queued ([`do_renameat2`](https://github.com/torvalds/linux/blob/v6.8/fs/namei.c#L4975) around `vfs_rename` and its `fsnotify_move`, [`iterate_dir`](https://github.com/torvalds/linux/blob/v6.8/fs/readdir.c#L103)), an ordering taken from the kernel source, not from inotify(7), which promises none; a directory registered with `NOTE_EXTEND` on Windows is accepted, as `vfs_kqfilter` does not check it, but never receives it, because the directory handle cannot tell a move between directories from a removal plus an addition. FreeBSD's hints depend on the filesystem and the console's filesystems are not known: a growing `ftruncate` reports `NOTE_WRITE | NOTE_EXTEND` where `vop_setattr_post` reports `NOTE_ATTRIB`, and on Windows `utimes` on a file reports `NOTE_WRITE`. The three Windows notifications are told apart in the error, which names the `parent`, `entries` or `subdirectories` watch, the path it was given and `GetLastError`, but a `FindFirstChangeNotification` that fails still throws rather than returning an error to the guest: the EVFILT_VNODE attach path is [`vfs_kqfilter`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L4936), which returns `EINVAL`, `ENOMEM` or 0 after `fget` has turned a descriptor that is not open into `EBADF`, and consults no directory permission, so no FreeBSD errno stands for a host that refuses to notify, and what the console does on such a host is not measured. Only the `parent` watch can fail this way in practice: `entries` and `subdirectories` need the `FILE_LIST_DIRECTORY` that opening the watched directory already took. The parent handle produces no hint of its own, as `RunHostWatch` only calls `FindNextChangeNotification` on it, so a later change may leave the watch on its 50 ms poll instead of throwing; that is not done here. Windows uses `FindFirstChangeNotification` on the parent directory (and on a watched directory itself) and compares `GetFileInformationByHandleEx` snapshots at least every 50 ms, because a write through an open handle is reported only when the handle is flushed or closed, so file hints can arrive 50 ms late, and a file deleted while watched, which the POSIX delete of Windows 10 1903 moves into `$Extend\$Deleted` until its last handle closes, reports `NOTE_DELETE` without `NOTE_RENAME` and keeps its handle without a parent directory watch, as that directory cannot be watched; Linux uses inotify on the file and is not run. `NOTE_REVOKE`, `NOTE_OPEN`, `NOTE_CLOSE`, `NOTE_CLOSE_WRITE`, `NOTE_READ`, unknown bits and descriptors other than files, directories, pipes and sockets throw. `sceKernelAddFileEvent(eq, fd, watch, udata)` and `sceKernelDeleteFileEvent(eq, fd)` take the [OpenOrbis](https://github.com/OpenOrbis/OpenOrbis-PS4-Toolchain/blob/0a1aaf9d/include/orbis/libkernel.h#L35) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0/src/SharpProspero/Interop/Kernel/KernelEqueue.cs#L164) signatures; `watch` is taken as the `fflags` and the event is added with `EV_CLEAR`, neither confirmed on a title (feat(libkernel): implement kevent EV_DISABLE, EV_DISPATCH and EV_FORCEONESHOT)
+- [kqueue and kevent](../../../core/libs/prx/libkernel/Equeue/src/Kqueue.cpp) (libkernel) follow FreeBSD 11's [`kern_event.c`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/kern_event.c) (`kqueue_kevent`, `kqueue_register`, `kqueue_scan`, the timer and user filters) over the event queue; nothing is measured on a console. The descriptor is a host null device registered as the kqueue: `close` and `sceKernelClose` close the queue and `dup`/`dup2` of it throw, but `read`, `write` and `fstat` act on the null device instead of failing with `EOPNOTSUPP` or reporting `S_IFIFO`. Read and write events are supported on guest sockets only, plus the timer, user and [vnode](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) filters; other filters, `NOTE_LOWAT`, `EV_CLEAR` on a socket, `EVFILT_READ` on another kqueue, a `NOTE_NSECONDS` period above one second with a fraction (11.0 converts the fraction with the microsecond macro) and any change to an existing timer (11.0 keeps the armed expiry and applies the new period after it, 11.4's `filt_timertouch` restarts it) throw. `EV_DISABLE`, `EV_DISPATCH` and `EV_FORCEONESHOT` follow kern_event.c: a disabled knote stays registered, stops polling or firing and is not reported, a trigger raised while it is disabled is kept and reported after `EV_ENABLE`, where `knote` would drop it, `EV_DISPATCH` reports once and then disables the knote, and `EV_FORCEONESHOT` is ignored on a new knote while on an existing one it sets `EV_ONESHOT` and fires the knote; a negative `nevents` fails with `EINVAL`. A new user event keeps its `fflags` unmasked and is not triggered by `NOTE_TRIGGER`, because `filt_userattach` reads the already cleared `kn_fflags`. The timer limit `kq_calloutmax` (`ENOMEM`) is not enforced, and closing a kqueue wakes a thread waiting on it in `kevent` with `EBADF`, where `kqueue_drain` makes the close wait for that thread. A level-triggered event is reported once per call and moved behind the other events, as in `kqueue_scan`; the `sceKernel*Equeue` calls keep their own collection loop

 - [sem_timedwait](../../../core/libs/prx/libkernel/Pthread/Posix/Sem.cpp) (libkernel) consumes an available count before checking the timeout and waits indefinitely for a null timeout, following FreeBSD 11's `sem_timedwait`. Console behavior for null and invalid timeouts when a count is available is unverified.
 - [tcsendbreak, tcdrain, tcflush, tcflow, tcgetpgrp, tcsetpgrp](../../../core/libs/prx/libkernel/File/src/Terminal.cpp) (libkernel) follow FreeBSD 11.4's [`termios.c`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/gen/termios.c): `tcflush` answers `EINVAL` for a queue other than `TCIFLUSH`, `TCOFLUSH` or `TCIOFLUSH` and `tcflow` for an action outside `TCOOFF`..`TCION` before the descriptor is looked at, and every other call fails as its terminal ioctl does on a descriptor that is not a terminal, with the errors `tcgetattr` gives, so `tcsendbreak` never reaches its 0.4 s pause. FreeBSD's `pipe_ioctl` answers `TIOCGPGRP` and `TIOCSPGRP` on a pipe or FIFO with the descriptor's SIGIO owner, which is not modelled, so `tcgetpgrp` and `tcsetpgrp` throw on a host pipe or FIFO above descriptor 2; descriptors 0 to 2 are taken as non-terminals that are not pipes, whatever the host attaches to them, so a pipe the guest creates on a freed descriptor 0 to 2 gets `ENOTTY` there. The PS5 `libkernel` is assumed to use this FreeBSD code, and `tcdrain` is not a cancellation point here
 - [Windows file timestamps](../../../core/libs/prx/libkernel/File/include/WindowsFileTime.hpp) use the host filesystem's timestamp range and resolution. `utimes`, `futimes`, and `lutimes` reject timestamps outside nonnegative signed 64-bit Windows file-time ticks with `EINVAL`, including exactly 1601-01-01 00:00:00 UTC, whose zero value means "leave unchanged" to `SetFileTime`. Guest directory descriptors still resolve through their recorded path. Filesystems with coarser timestamp resolution cannot retain every guest microsecond

Subject: [PATCH 0223/1000] perf(agc): draw an indirect rect list from its
 records on the GPU

ClassifyIndirectDraw sent every indirect rect-list draw to the CPU path
(non-vertex path), which reads the records on the CPU. When the GPU writes
those records earlier in the frame, the read waits for every batch up to
the producer: in Kena (PPSA01802) each such DRAW_INDIRECT waited about
15 ms, about once per frame.

A rect list on the vertex path is drawn by its generated tessellation
stages from three-vertex patches, with no draw-dependent constants, so the
records can be consumed on the GPU like any vertex-path draw. The
classifier now keeps a rect list without mesh or tessellation stages on
the GPU path, and Graphics::Draw accepts it. APS5_NO_RECT_INDIRECT=1
restores the CPU path.

agc_driver_rect_list_indirect submits a direct rect-list draw and the
same rectangle from a DRAW_INDIRECT record and requires the same bytes,
and a record without vertices to draw nothing; it passes on either path.
agc_driver_draw_offset_indices requires an auto indirect rect-list record
whose packet names no offset registers to be classified to the GPU.

Subject: [PATCH 0229/1000] fix(agc): keep a build's BDA table disjoint where
 its read-only copy overlaps the address space

A read-only V# that crosses imports of the cached address space is bound
through a copy of its bytes, and that copy can begin inside an import. The
BDA table listed the copy and the space's ranges by begin, and a shader
takes the last range beginning at or below an address, so the bytes from
the copy's begin to the end of that import resolved to the copy. The copy
is read-only, so a BDA store or atomic into a writable import faulted with
Permission, the GPU side of the rule owner() no longer applies on the CPU.

The table now gives every byte one range: the space's ranges, or after a
dissolve the direct and mirrored regions, keep the bytes they hold, and a
build's copies keep only the bytes nothing live holds.

Subject: [PATCH 0231/1000] test(agc): prove the merged read-only V# test keeps
 the address space, and cross access

The test of two read-only V#s merged over three imports now asserts that
its second build hits the cached address space without a dissolve and that
the third leaves it only for the import change. One crossed piece is
writable, so a join of the crossed run cannot erase the overlap the test is
about.

Subject: [PATCH 0232/1000] test(agc): store through a written V# merged with a
 read-only V# past an import

A read-only V# across two imports into unregistered memory, a read-only and
a written V# in that memory: UploadPrepare merges the three into one copy
that begins inside the first import. The written V# maps its own bytes in
that copy, counts as a copied write, and WriteBack lands its store on its
bytes alone.

Subject: [PATCH 0233/1000] test(agc): name the overlay statistics test's
 tolerance check within

MinGW's minwindef.h defines near and far as empty macros, so a helper
named near stops compiling in any test that comes to include windows.h.
The project keeps those names out of its code.

Subject: [PATCH 0234/1000] test(agc): lift the host import budget in the
 sparse dma-buf import test

The test imports ranges just above udmabuf's size limit and keeps the first
one live. With size_limit_mb=8192 each range is 8257 MiB, so on a host with
32 GB of RAM the default budget (half the physical memory) refuses the second
import and HostImportFor returns nullptr instead of reaching the sparse path:
"a failure at UDMABUF_CREATE after the sparse path was chosen did not throw".

Subject: [PATCH 0236/1000] fix(shader): bind a T# whose record the CPU
 evaluates directly when a table cannot express its operation

An image table cannot store, update atomically or read PCK and BY2/BY4
through its records (#757): those operations fault and read zeros. #6243
turns a heap T# whose words and record offset the SRT walker evaluates
into a selected one-record table, which kept that limitation although
such a T# is one known descriptor, as #5188's direct images were.

PlanTableColumns now binds such a T# directly, for every operation of the
shader on it, when any of them is a store, an atomic, a packed or a
BY2/BY4 access. A T# keyed per lane, or by a value the walker cannot
evaluate, keeps its table and its unsupported-operation fault. The disk
format moves to 37 so that plans cached by #6243's builds are not reused.

A key the walker evaluates selects its one record instead, unless the shader may write the memory the key is read from at run time (the same buffer, or any memory when the read or a write goes through a pointer or a GPU-only descriptor); then the column binds the whole domain too. A write to the key's memory through another V# over the same bytes is not detected.

Subject: [PATCH 0237/1000] test(shader): store, update atomically and read
 packed through a T# whose record the CPU evaluates

verifySelectedRecordDirectOperations plans image_store, image_atomic_add,
image_load_pck and image_load_by2 through a heap T# keyed by an SRT value,
which must be bound directly, and through a T# keyed per lane, which must
stay a table with its unsupported mark. A T# that is both sampled and
stored is bound directly for both, and one that is only sampled still
selects its record.

RunSelectedStoreTests stores through a record keyed by an SRT value on the
GPU and reads the texels back. Before the fix both failed: the T# was
planned through an image table, and the store faulted as an unsupported
operation.

Subject: [PATCH 0238/1000] test(shader): pin that an S# whose record the CPU
 evaluates is bound directly

A sampler column is planned only when DirectSampler cannot evaluate the
S#, so no sampler record is ever selected: an S# read from a heap at an
offset the SRT walker evaluates is a direct sampler, and one keyed per
lane is a sampler table.

Subject: [PATCH 0239/1000] perf(shader): drop NonUniform from the index of a
 selected image table record

A selected record is one map entry for the whole dispatch, so its
descriptor index is dynamically uniform. The emitter decorated it
NonUniform like any table index whenever the workgroup spans more than
one subgroup, and on every graphics stage, which makes drivers scalarize
the access. The element index, its access chain, the loaded image and the
sampled image of a selected record are no longer decorated; table
samplers and tables keyed per lane keep the decoration.

Subject: [PATCH 0241/1000] fix(shader): clear the key domains of a column
 deselected because its key may be written

CheckTableStores deselects a selected column whose key the dispatch may
write: a key read through a pointer or a V# while the shader stores
through a pointer, or through a V# the shader writes. The column kept the
key domains narrowed from that same key buffer, which the domain rule
clears only when the domain's own V# is written, so a shader storing
through a pointer still narrowed its whole table on a key it may
overwrite. Deselection now clears them as well.

On Windows a receive on a datagram socket with no local address waits
for one. A sceNetShutdown of the receive side now ends that wait, and
later receives return 0 at once; a zero-length receive returns 0 without
waiting. FreeBSD's soreceive_dgram returns 0 in both cases. Before, a
thread blocked in such a receive kept waiting after the socket was shut

 - [sceNetGetsockopt](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) reads `SO_ERROR` from the host socket. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `sceNetConnect`; a second failure with the same code on the same socket without a `sceNetConnect` in between would be hidden.
 - [sceNetSendmsg and sceNetRecvmsg](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) copy the scatter/gather list through one host buffer and accept only the flags `sceNetSend`/`sceNetRecv` accept. Sending control data throws; a receive never returns control data (`msg_controllen` 0), since no socket option that queues it is supported
 - [MSG_DONTWAIT](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) in `sceNetSend`, `sceNetSendto`, `sceNetRecv`, `sceNetRecvfrom`, `sceNetRecvmsg` and `sceNetSendmsg` makes that one call non-blocking through the host's `MSG_DONTWAIT`, as FreeBSD 11.4's `soreceive_generic` returns `EWOULDBLOCK` for it (`sys/kern/uipc_socket.c`); the value `0x80` is FreeBSD's (`sys/sys/socket.h`) and [shadPS4's](https://github.com/shadps4-emu/shadPS4/blob/e0a466753a1aacbc8db8253be685bf7ab4d9daae/src/core/libraries/net/net_types.h#L104).

Winsock fails such a receive with `WSAEINVAL`, where FreeBSD 11.4's `soreceive_dgram` waits for a datagram (`sys/kern/uipc_socket.c`). A non-blocking socket fails with `EAGAIN` at once, and the receive timeout ends the wait with `EAGAIN`; when the address comes first, the host receive that follows waits the whole timeout again, so the call can take up to twice the timeout. An abort or close ends the wait, and the host receive then fails as it did before

A non-blocking socket fails with `EAGAIN` at once, and the receive timeout ends the wait with `EAGAIN`; when the address comes first, the host receive that follows waits the whole timeout again, so the call can take up to twice the timeout. A `sceNetShutdown` of the receive side ends the wait and the receive returns 0, and a zero-length receive returns 0 without waiting, as `soreceive_dgram` does when the socket can't receive more or nothing was asked for. An abort or close ends the wait, and the host receive then fails as it did before
 - [sceNetResolverAbort and sceNetResolverStartNtoaMultipleRecords](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) follow shadPS4 ([net.cpp](https://github.com/shadps4-emu/shadPS4/blob/811bfcd7d17ed8ae975c477d9ff28abc744e1ca8/src/core/libraries/net/net.cpp), [net_resolver.cpp](https://github.com/shadps4-emu/shadPS4/blob/811bfcd7d17ed8ae975c477d9ff28abc744e1ca8/src/core/libraries/net/net_resolver.cpp)); the `(int rid, int flags)` signature of the abort also matches [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Net/Socket.cs). Unverified on hardware. Lookups run synchronously over the host resolver, which cannot be interrupted: an abort while a lookup runs on another thread returns at once, and that lookup fails with `EINTR` without writing its output only when the host call returns; the abort flags are then ignored, as shadPS4 does for a running lookup. With nothing running, abort flag 1 (NTOA preservation) or 2 (ATON preservation) makes the next `sceNetResolverStartNtoa*` or `sceNetResolverStartAton` call on that resolver fail with `EINTR`, reported by `sceNetResolverGetError`, after its arguments are checked. Unlike shadPS4, which ignores them, other abort flag bits throw, and `sceNetResolverStartNtoaMultipleRecords` throws for any flag, including async (1) and 0x10000 (IP address literals disabled), as `sceNetResolverStartNtoaMultipleRecordsEx` does
 - [sceNetResolverStartNtoa6](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) resolves a host name to its first IPv6 address through the host resolver (`getaddrinfo` with `AF_INET6`) and writes the 16-byte address; the `(rid, hostname, addr, timeout, retry, flags)` signature follows `sceNetResolverStartNtoa`. A name with no IPv6 address fails with `RESOLVER_ENODNS` (`0x804101E1`) like a failed lookup; whether the console returns IPv4-mapped addresses instead is not verified. Timeout and retry are ignored as in `sceNetResolverStartNtoa`, and any nonzero flags throw because their meaning for this call is not known. Unverified on hardware.

The argument registers match [Jelly5](https://github.com/02dnot/Jelly5/blob/552b866d89b2a58b27f7f7b0484dc743ce235526/app/src/jelly5_bitstream.cpp#L26-L28) and PPSA99051's [bitstream_out.cpp](https://github.com/sainsaji/PS5-Audio-Passthrough-Research/blob/cf3c921d79bf00db4847f31b68a7bd95a8037cd7/sample-app/src/platform/ps5/bitstream_out.cpp#L29-L32). Audio reaches the host through SDL as PCM and the host has no HDMI bitstream output, so an Ex port has no host device: `sceAudioOutOutput` paces it at its own rate and drops its IEC 61937 bursts, and `sceAudioOutExConfigureOutput` changes nothing. Nonzero `flags` or `option`, other modes or targets, `sceAudioOutExClose` of a handle that is not an Ex port, and `sceAudioOutGetPortState` on an Ex port throw, since the console's answers are unknown

Subject: [PATCH 0245/1000] test(libSceNet): receive on an unbound datagram
 socket that another thread binds or connects

The test covered a send that names the waiting socket. A bind and a
datagram connect from another thread name it too: each case now waits in
sceNetRecv on the unbound socket, binds or connects it, and checks that a
peer's datagram to the new address reaches the waiting receive.

Subject: [PATCH 0246/1000] perf(libSceNet): end the wait for a local address
 when a bind, connect or send gives one

A receive on an unbound datagram socket checked the host socket every
10 ms, so it went on waiting up to 10 ms after another thread's bind,
connect or send had named the socket. sceNetBind now wakes the waiting
receives. On Windows a datagram connect or a send marks the socket bound
and wakes them once the host socket has its local address; a raw socket
that a send leaves without one stays unmarked and keeps waiting.

Subject: [PATCH 0247/1000] fix(agc-driver): release the texture caches when a
 device allocation runs out of memory

A buffer allocation that still fails after the pool trimmed its own free slots now asks the texture caches for the request plus a reserve (the request again, at least 256 MiB) and retries once more: sampled textures go first, oldest first, then cached storage images, oldest first, with their resource cache entries removed and kept by the active recorder as an eviction from the lookup does. Only bytes whose images die now count; images a recorded batch still holds do not. The caches are skipped when the calling thread holds their mutex (an allocation inside a lookup) or the device lock cannot be taken, so the retry never waits behind a lookup. The recovered line names the released bytes next to the reclaimed ones, as does the failure.

Before this, the title PPSA15304 died 460 s into its second section on a 128 MiB buffer allocation while 2.5 GiB of cached storage images were idle.

(cherry picked from commit 31b1b227657dd7b9ced8d808a224411673d6de1c)

Subject: [PATCH 0248/1000] fix(agc-driver): allocate texture and storage image
 memory through the buffer pool's recovery path

Sampled textures, depth copies and storage images allocated their device memory directly and threw on the first VK_ERROR_OUT_OF_DEVICE_MEMORY. They now go through BufferPool::AllocateMemory, so a failed image allocation trims the pool's idle buffers, releases the texture caches and retries like a buffer allocation does, and reports the recovery the same way.

Subject: [PATCH 0249/1000] fix(agc-driver): release clean storage images
 before ones with pending results

Evicting a storage image whose results are still on the GPU stores them to guest memory first, and that store needs a staging buffer: under memory pressure the release itself ran out of device memory and the title died on the nested allocation (PPSA15304 at 125 s on a 64 MiB write-back buffer). The release now takes clean images oldest first and turns to dirty ones only when the clean ones did not free enough; a failure inside the release is reported and ends it, leaving the outer allocation to retry with what was freed.

Subject: [PATCH 0250/1000] fix(agc-driver): size the staging pool from the
 device's reported memory budget

The device tier of the buffer pool kept an eighth of the device-local heap (2 GiB on a 16 GiB card) whatever VK_EXT_memory_budget said the process may use. Its budget is now the smaller of an eighth of the heap and an eighth of the reported budget, at least 512 MiB; APS5_STAGING_POOL_MIB still overrides it.

(cherry picked from commit b039e1da12d7cedc3bfdf0c1d3c0c354f3cd58aa)

Subject: [PATCH 0251/1000] fix(libSceNet): keep one receive timeout across the
 wait for a local address

When the address came during the wait, the host receive that followed
waited its whole SO_RCVTIMEO again, so a receive could take up to twice
the timeout. FreeBSD's soreceive_dgram sleeps once per timeout. Now the
receive waits for a datagram with WSAPoll only for what is left of the
timeout, and fails with EAGAIN when it runs out, as before. Nothing
changes when the socket already had an address or has no timeout.

Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `sceNetConnect`; a second failure with the same code on the same socket without a `sceNetConnect` in between would be hidden.
 - [sceNetSendmsg and sceNetRecvmsg](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) copy the scatter/gather list through one host buffer and accept only the flags `sceNetSend`/`sceNetRecv` accept. Sending control data throws; a receive never returns control data (`msg_controllen` 0), since no socket option that queues it is supported
 - [MSG_DONTWAIT](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) in `sceNetSend`, `sceNetSendto`, `sceNetRecv`, `sceNetRecvfrom`, `sceNetRecvmsg` and `sceNetSendmsg` makes that one call non-blocking through the host's `MSG_DONTWAIT`, as FreeBSD 11.4's `soreceive_generic` returns `EWOULDBLOCK` for it (`sys/kern/uipc_socket.c`); the value `0x80` is FreeBSD's (`sys/sys/socket.h`) and [shadPS4's](https://github.com/shadps4-emu/shadPS4/blob/e0a466753a1aacbc8db8253be685bf7ab4d9daae/src/core/libraries/net/net_types.h#L104).

Winsock fails such a receive with `WSAEINVAL`, where FreeBSD 11.4's `soreceive_dgram` waits for a datagram (`sys/kern/uipc_socket.c`). A non-blocking socket fails with `EAGAIN` at once, and the receive timeout ends the wait with `EAGAIN`; when the address comes first, the host receive that follows waits the whole timeout again, so the call can take up to twice the timeout. A `sceNetShutdown` of the receive side ends the wait and the receive returns 0, and a zero-length receive returns 0 without waiting, as `soreceive_dgram` does when the socket can't receive more or nothing was asked for. An abort or close ends the wait, and the host receive then fails as it did before

Unverified on hardware. Lookups run synchronously over the host resolver, which cannot be interrupted: an abort while a lookup runs on another thread returns at once, and that lookup fails with `EINTR` without writing its output only when the host call returns; the abort flags are then ignored, as shadPS4 does for a running lookup. With nothing running, abort flag 1 (NTOA preservation) or 2 (ATON preservation) makes the next `sceNetResolverStartNtoa*` or `sceNetResolverStartAton` call on that resolver fail with `EINTR`, reported by `sceNetResolverGetError`, after its arguments are checked. Unlike shadPS4, which ignores them, other abort flag bits throw, and `sceNetResolverStartNtoaMultipleRecords` throws for any flag, including async (1) and 0x10000 (IP address literals disabled), as `sceNetResolverStartNtoaMultipleRecordsEx` does
 - [sceNetResolverStartNtoa6](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) resolves a host name to its first IPv6 address through the host resolver (`getaddrinfo` with `AF_INET6`) and writes the 16-byte address; the `(rid, hostname, addr, timeout, retry, flags)` signature follows `sceNetResolverStartNtoa`. A name with no IPv6 address fails with `RESOLVER_ENODNS` (`0x804101E1`) like a failed lookup; whether the console returns IPv4-mapped addresses instead is not verified. Timeout and retry are ignored as in `sceNetResolverStartNtoa`, and any nonzero flags throw because their meaning for this call is not known. Unverified on hardware.

+### Silent stubs
+- [fchmodat](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) - `AT_SYMLINK_NOFOLLOW` on a symbolic link (on Windows and Linux)
+
 ### Functional
 
 - [fchdir](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) changes the guest working directory to the descriptor's directory: on Windows through the path recorded when the descriptor was opened, on Linux through the `/proc/self/fd` link target. It returns `EBADF` for a descriptor that is not open and `ENOTDIR` for one that is not a directory. FreeBSD `change_dir`'s search-permission check (`EACCES`) is not modelled, and a directory renamed after it was opened is still reached through the recorded path. Console behaviour is unverified
 - [openat](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) passes `AT_FDCWD` (-100) and absolute paths to `open`. Any other relative path is joined to the descriptor's host directory, found the same way as for `fchdir`, so guest path aliases and case-insensitive name matching do not apply to it, and a `..` component is not kept inside the guest root. It returns `EBADF` for a descriptor that is not open and `ENOTDIR` for one that is not a directory. As with `open`, `O_NOFOLLOW` and `O_NONBLOCK` are ignored. PPSA99003 opens directory entries this way. Console behaviour is unverified
-- [fchmodat](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) passes `AT_FDCWD` (-100) and absolute paths to `chmod`; any other relative path is joined to the descriptor's host directory the same way as for `openat`, so guest path aliases and case-insensitive name matching do not apply to it and a `..` component is not kept inside the guest root. A flag other than `0` or `AT_SYMLINK_NOFOLLOW` (0x200) returns `EINVAL`; the mode is masked to `07777`. With `AT_SYMLINK_NOFOLLOW` a symbolic link throws, since the host cannot change a link's own mode, while a regular file is changed either way. The mode maps to the host file mode, which on Windows is only the CRT's read-only bit. PPSA99621 calls it through `std::filesystem::permissions`. Console behaviour is unverified

The mode maps to the host file mode, which on Windows is only the CRT's read-only bit. PPSA99621 calls it through `std::filesystem::permissions`. Console behaviour is unverified
 - [pathconf](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) looks the path up as FreeBSD 11's `kern_pathconf` does (links followed, `ENAMETOOLONG` for a path of 1024 bytes or more or a component over 255) and returns the constants of FreeBSD 11's UFS `ufs_pathconf` for files and directories alike: `_PC_LINK_MAX` 32767, `_PC_NAME_MAX` 255, `_PC_PATH_MAX` and `_PC_SYMLINK_MAX` 1024, `_PC_PIPE_BUF` 512, `_PC_CHOWN_RESTRICTED` and `_PC_NO_TRUNC` 1, `_PC_FILESIZEBITS` 64, `_PC_REC_MAX_XFER_SIZE` -1, `_PC_PRIO_IO` and `_PC_SYNC_IO` 0. Whether the console's filesystems report the same is not verified. It throws for the names whose UFS value depends on the mount (`_PC_ALLOC_SIZE_MIN`, `_PC_REC_INCR_XFER_SIZE`, `_PC_REC_MIN_XFER_SIZE`, `_PC_MIN_HOLE_SIZE`), the kernel options (`_PC_ACL_EXTENDED`, `_PC_ACL_PATH_MAX`, `_PC_ACL_NFS4`, `_PC_MAC_PRESENT`) or the page size (`_PC_REC_XFER_ALIGN`), and on which UFS and `vop_stdpathconf` disagree (`_PC_MAX_CANON`, `_PC_MAX_INPUT`, `_PC_VDISABLE`, `_PC_ASYNC_IO`); other names fail with `EINVAL`
 - [mkdirat](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) passes `AT_FDCWD` (-100) and absolute paths to `mkdir`. Any other relative path is joined to the descriptor's host directory, found the same way as for `fchdir`, so guest path aliases and case-insensitive name matching do not apply to it, and a `..` component is not kept inside the guest root. It returns `EBADF` for a descriptor that is not open and `ENOTDIR` for one that is not a directory. On Windows, `mode` is ignored. Console behaviour is unverified
 - [readlink](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) on Windows reads a symbolic link's target from its reparse data and returns it with `/` separators, only when the target is relative, as `symlink` creates them. A symbolic link with an absolute target and a junction throw, as a host path has no guest form. Any other reparse point throws too, where FreeBSD reports `EINVAL` for a file that is not a link

 - [wcsftime](../../../core/libs/prx/libc/src/Time.cpp) (libc) follows FreeBSD 11.4's [wcsftime.c](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/locale/wcsftime.c) over this library's `wcsrtombs`, `strftime` and `mbsrtowcs` in the single-byte C locale of [none.c](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/locale/none.c), with the guest's 16-bit `wchar_t`, without console verification. It has the `strftime` gaps above. A format unit above 255 returns 0 with `EILSEQ`; an empty result, a result that does not fit and a null buffer return 0 with `errno` unchanged, discarding the `ERANGE` or `EINVAL` that the Windows CRT's `strftime` sets. A null format or `tm` throws, where FreeBSD dereferences it (a null `tm` is read there only when the format has a conversion that needs it)
 - [syslog](../../../core/libs/prx/libc/src/Syslog.cpp) (libc) writes each message to `stderr` as `[syslog:<priority>] <message>`, with a newline added when missing, instead of sending it to the console's system log. Priority and facility handling follow FreeBSD's `vsyslog`: `%m` expands to the guest errno's message, unknown bits are reported (as priority 0x23, since FreeBSD passes `LOG_ERR|LOG_CONS|LOG_PERROR|LOG_PID` as the priority) and masked, a missing facility becomes `LOG_USER` or the facility set by `openlog`, and errno is preserved. `openlog` applies its identity and `LOG_PID`; a null identity retains the previous one, and a valid nonzero facility replaces the default. `closelog` clears the identity but retains the options and facility, as in FreeBSD 11; when no identity is set, FreeBSD falls back to the program name, which this backend does not emit. `LOG_PERROR` has no extra effect because stderr is the emulated log sink; `LOG_NDELAY`/`LOG_ODELAY`, `LOG_NOWAIT` and `LOG_CONS` have no daemon, child or console backend to control. `setlogmask` follows [FreeBSD 11](https://github.com/freebsd/freebsd-src/blob/8d2708de5d6112a492744d367cfdfb8fd219227a/lib/libc/gen/syslog.c): the process-wide mask defaults to 0xff, zero queries it, and nonzero values replace it; masked messages are skipped before formatting, including the unknown-priority diagnostic. The console's mask behaviour is unverified
 - [daemon](../../../core/libs/prx/libc/src/Process.cpp) (libc) throws: forking into the background is not supported. PPSA85300 imports it and fails to load without it. VLC 3.0 calls it only when its `daemon` option is set ([libvlc.c](https://github.com/videolan/vlc/blob/6de05adcbaf2e8b85fe86aad4169393098628119/src/libvlc.c#L190-L197)), and the title starts libVLC with `--ignore-config` and without `--daemon` ([player.cc](https://github.com/ZiZc3/VLC/blob/f3253020a64368153233ede29183014c0b6c8979/src/player.cc#L960-L981))
-- [Call tracing](../../../core/libs/prx/libc/src/specifics/windows/CallTrace.cpp) (`APS5_TRACE_CALLS`) exists on Windows only and records the entry of a call, not its arguments or its result. Nothing passes imports through `TraceImport_nid_no_patch` yet, so no title is traced. One process-wide ring keeps the last 65536 calls, so a thread that calls often pushes the others out. Calls are also counted per traced target since start-up; an import bound to a target already traced under another name is counted under the first name. The thunk saves the integer argument registers and `xmm0` to `xmm7`; arguments in wider vector registers pass only as long as the recording code stays free of AVX instructions, which is not tested
 - [_WStoul](../../../core/libs/prx/libc/src/Strings.cpp), [_Iswctype](../../../core/libs/prx/libc/src/RuneLocale.cpp), [swscanf_s and swscanf](../../../core/libs/prx/libc/src/ScanningWide.cpp) (libc) - `_WStoul` is `wcstoul` and throws for a base other than 0 or 2 to 36. `_Iswctype` takes the class numbers of Dinkumware's [xwcc.h](https://github.com/superna9999/ti-cgt6x/blob/cgt6x_7_3_4/include/xwcc.h) (1 `alnum` to 11 `xdigit`, 12 `blank`) and throws for any other value, including the FreeBSD masks `wctype` returns; the numbering is not confirmed on the console's `libc.prx`. `swscanf_s` follows C11 7.29.2.2 and K.3.9.1.5, but reads the size argument as `unsigned int` like `sscanf_s` where K.3.9.1.5 specifies `rsize_t`; the console's width is unverified. A runtime-constraint violation (null buffer, format or receiving pointer) only returns `EOF`, and a too small array gets a null first element as in `sscanf_s`. A literal mismatch is a matching failure and a field that is only a prefix, such as `0x` or `1e`, does not convert, as C11 requires; FreeBSD's `vfwscanf` reports an input failure for the first and converts the second. Integers out of range are truncated from `strtoll`/`strtoull`. It throws for `%p`, `%S`, `%C`, unknown length modifiers, scanset ranges, `%n` with suppression or width, and narrow `%s`, `%c` or `%[` input that the C-locale `wcrtomb` cannot convert. `swscanf` runs the same scanner without the size arguments of `%s`, `%c` and `%[`, as FreeBSD's [swscanf.c](https://github.com/freebsd/freebsd-src/blob/d106002967eff712894ab8b5337bbbff106ce5e0/lib/libc/stdio/swscanf.c) passes its arguments to `vswscanf`, so everything above except the sizes applies to it; it also keeps the null buffer, format and receiving pointer checks returning `EOF`, where C leaves those undefined. Neither variant is confirmed on a PS5 title
 - [flock](../../../core/libs/prx/libc/src/FileLock.cpp) (libkernel) on Windows shares one lock state between duplicated descriptors, following FreeBSD 11.4's [flock(2)](https://github.com/freebsd/freebsd-src/blob/releng/11.4/lib/libc/sys/flock.2). Independent opens have separate states; closing a descriptor or reopening a stream drops only its reference. Lock transitions on one open file description are serialized. The lock is a host [LockFileEx](https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-lockfileex) lock on one byte at offset 2^63 - 2, which no file reaches, so it excludes other `flock` calls and leaves reads, writes and mapped views alone, like FreeBSD's advisory locks. Console behavior, signal interruption and concurrent closure of a descriptor while its lock call is pending are unverified.
 - [std::_Throw_Cpp_error](../../../core/libs/prx/libc/src/exception/StandardExceptions.cpp) (libSceAmpr) follows Dinkumware's `thread0.cpp` as shipped with [Visual C++ 2013](https://github.com/ganboing/crt.vc12/blob/f1d47126bf13d1c9dccaa6c53b72217fd0474968/src/thread0.cpp) and in [microsoft/STL](https://github.com/microsoft/STL/blob/da52dc0fcadbd83690cfd1ed32408d2847439493/stl/src/thread0.cpp), without console verification. `_Cpp_error` codes 0 to 6 throw a guest `std::system_error` whose `error_code` holds the FreeBSD errno of the `errc` value (EBUSY 16, EINVAL 22, ESRCH 3, ENOMEM 12, EPERM 1, EDEADLK 11, EAGAIN 35) and the generic category, and whose `what()` is the table message, `": "` and the generic category's message for that errno, selected by the first matching errno entry in VC12's [`syserror.cpp`](https://github.com/ganboing/crt.vc12/blob/f1d47126bf13d1c9dccaa6c53b72217fd0474968/src/syserror.cpp); another code throws `std::out_of_range` on the host instead of reading past the table. The guest `system_error` is taken to be [VC12's](https://github.com/ganboing/crt.vc12/blob/f1d47126bf13d1c9dccaa6c53b72217fd0474968/src/system_error): the 16-byte `runtime_error` followed by `error_code {int, const error_category*}`, 32 bytes, so its copy constructor and assignment copy the code too. The generic category is a static libc object with VC12's `error_category` virtual order (destructors, `name`, `message`, `default_error_condition`, the two `equivalent`), not the console's `_Error_objects<int>::_Generic_object`, and the new `generic_category()` export returns that object; a title's inline category object in a bundled libc can still have a different identity. Its `message` and direct message export construct the existing [GuestLocale::String](../../../core/libs/prx/libc/include/GuestLocale.hpp) model: a reserved eight-byte word, 16-byte inline buffer, length and capacity, with guest `operator new` storage above 15 bytes. This 40-byte string layout and virtual return ABI have not been verified against a console library. The deleting destructor still throws. `_Syserror_map` covers the 72 distinct Dinkumware `errc` values present in FreeBSD 11.4 [errno.h](https://github.com/freebsd/freebsd-src/blob/releng/11.4/sys/sys/errno.h), returning null for other values; category messages use `unknown error` for those. First-match aliases are `EAGAIN`/`EWOULDBLOCK` -> `operation would block` and `ENOTSUP`/`EOPNOTSUPP` -> `not supported`. STREAMS-only errno assignments absent from that header (`ENODATA`, `ENOSR`, `ENOSTR`, `ETIME`) are not inferred

Subject: [PATCH 0254/1000] fix(relinker): check PT_LOAD and uncovered
 PT_SCE_RELRO file ranges

ElfReader::ReadProgramHeaders checked that a PT_LOAD's file size does
not exceed its memory size, but not that its file range lies inside the
input. The Windows and macOS writers reject such a segment later; the
Linux patcher keeps the original PT_LOADs and appends its own block at
the old end of the file, so a load reaching past the input mapped the
relinker's .dynstr, .dynsym and entry stub into the guest segment.

A PT_SCE_RELRO that no PT_LOAD covers is turned into a PT_LOAD after
the per-header checks, so it skipped them: a file size larger than its
memory size was accepted for Linux, and Windows and macOS reported a
file-range error instead.

Reject a PT_LOAD whose file range exceeds the input, and run the same
two checks on an uncovered PT_SCE_RELRO before converting it.

Subject: [PATCH 0255/1000] fix(relinker): drop the PT_LOAD range check made
 redundant in translation

ReadProgramHeaders now rejects a PT_LOAD whose file range exceeds the
input, so TranslateVirtualAddress no longer needs its own check. An
uncovered PT_SCE_RELRO outside the file reports the same "Segment offset
out of bounds" as a PT_LOAD, and a test pins that a load or uncovered
PT_SCE_RELRO ending exactly at the end of the file is still accepted.

Subject: [PATCH 0256/1000] ci(build): accept merged pull requests in the
 relinker author check

The eligibility job enabled the relinker matrix for a pull request only
when repos.listCommits on main with the author's login returned a
commit. That filter misses authors whose commits in main are not
matched to their login. On 2026-10-13 it found no commit for 26 authors
of open pull requests who have 1 to 44 pull requests merged into main,
so their pull requests skip the relinker, against CONTRIBUTING.md ("if
its author already has a commit in main").

When listCommits finds nothing, the job now also searches for the
author's merged pull requests into main, with the query pr-intake.yml
uses. Incomplete search results count as none. A failed search, such as
the search API's own rate limit, skips the relinker with a warning
instead of failing the job. Both requests now run only when the pull
request changes a relinker file, so other pull requests make neither.

test_build_eligibility.py runs the step's script in node with a mocked
github object and skips when node is missing.

Subject: [PATCH 0257/1000] feat(libSceAmpr): implement __cxa_call_unexpected

__cxa_call_unexpected takes the in-flight exception's unwind header and
never returns, as in libcxxabi. No std::set_unexpected is exported and
the exception header's unexpected handler is never set, so the handler
is always the default one, which calls std::terminate. It therefore
forwards to libc's __cxa_call_terminate, which begins the catch and runs
the current terminate handler; a null header terminates in libc's
__cxa_begin_catch. libcxxabi's std::terminate would instead run the
terminate handler saved in the exception header at throw time; the two
differ only if std::set_terminate was called in between, which the debt
entry records.

The test shares the forked-child helper of the std::_Pad test, which now
takes the terminate handler to install.

 - [AMPR command sizes](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - commands use the emulator's own encoding with an 8-byte header, so `Nop(n)` takes 8 + 4n bytes where the console record is n dwords including its header (`NopWithData(n)`: (n + 1) dwords). The measure functions agree with the appended sizes, but a title that pads to an exact offset or the end of the buffer with `Nop(remaining / 4)` gets `SCE_AMPR_ERROR_BUFFER_FULL` or a shifted offset. The at-start flag of the `_04_00` writes is ignored; commands run in order, each after the previous one completes
 - [APR map begin and end](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - as in ampr_emu, `MapBegin`/`MapDirectBegin` map when they run and `MapEnd` only closes the region; while a region is open a second begin and every completion write return `EPERM`, the at-start `_04_00` writes are accepted
 - [AMPR markers](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - signatures taken from the [ampr_emu](https://github.com/drakmor/ampr_emu) reimplementation, not confirmed on a title: `sceAmprCommandBufferSetMarkerWithColor` takes the color by pointer, the push and measure variants by value. Colors are not recorded
+- [__cxa_call_unexpected](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - takes the in-flight exception's unwind header and never returns, as [libcxxabi 18.1.8](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_personality.cpp#L1171-L1211) does. No `std::set_unexpected` is exported and the exception header's unexpected handler is never set, so the handler is always the default one, which calls `std::terminate` ([cxa_default_handlers.cpp](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_default_handlers.cpp#L88-L99)); it therefore forwards to libc's `__cxa_call_terminate`, which begins the catch and runs the current terminate handler. That matches libcxxabi except for which terminate handler runs: there `std::terminate` after `__cxa_begin_catch` ([cxa_exception.cpp L470-L477](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_exception.cpp#L470-L477)) runs the handler saved in the caught exception's header ([cxa_handlers.cpp L72-L93](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_handlers.cpp#L72-L93)), which `__cxa_throw` and `__cxa_init_primary_exception` set to `std::get_terminate()` when the exception is thrown ([cxa_exception.cpp L209-L214](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_exception.cpp#L209-L214), [L279](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_exception.cpp#L279)), while here the current global handler runs, as AnyPS5's own `std::terminate` does. The two differ only if `std::set_terminate` was called between the throw and this call. A null header terminates because this emulator's libc `__cxa_begin_catch` terminates on null (libcxxabi does not define that case). Dynamic exception specifications that would let a replaced unexpected handler throw a permitted type are not modelled

Subject: [PATCH 0258/1000] refactor(agc): add the overlay's driver time after
 the worker profile report

#6292 moves the APS5_PROFILE_DRAW check in Driver::timed to the top and
rewrites the report's condition, the two lines this branch's driver-time
line sat between, so the two conflicted. The line now follows the
report. It reads the same flag and times, so it counts the same.

Subject: [PATCH 0262/1000] fix(agc): fold bounded vertex lane masks before
 stencil replay

Preserve replay refusal for observable lane-dependent values, non-vertex stages, unknown subgroup widths and varying-size modules. Validate the actual native vertex subgroup contract and retain compiled single-lane targets.

Subject: [PATCH 0263/1000] fix(shader): fold only constant lower-half lane
 words of vertex programs

FoldVertexLaneBounds replaced every LaneId < 32 compare of a vertex
program on a fixed 32-lane host subgroup with true. The half-wave scan
matcher of the SPIR-V backend recognises a lane word by the select of its
low and high words on that compare. A scan keyed by the entry EXEC ballot
lost that shape, so its v_readlane_b32 of lane 63 was no longer read as a
half-wave reduction and the recompile failed (agc_shader_memory).

Fold the lane word select itself instead, and only when both words are
constants. Lane words built from ballots or other values keep their
lower-half test.

Subject: [PATCH 0264/1000] fix(agc): disable optional BMP dumps after host I/O
 failures

Use checked host stdio for BMP output and stop requesting dumps after the first write failure. Keep pixel validation, allocation and non-I/O failures on the existing fatal path.

 ### Unknown function info
 
+- [Optional BMP frame dumps](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) use checked host stdio. An open, header, pixel or close failure prints one diagnostic and disables subsequent BMP dumps for the process; queued frames drain without more file I/O. Pixel validation and allocation failures retain the existing fatal path. The CPU fixture checks identical BMP bytes and real pipe failures; hardware presentation after a storage error is unmeasured.
+
 - [Inactive vertex point size](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) - `PA_CL_VS_OUT_CNTL.USE_VTX_POINT_SIZE` is accepted for lines, triangles and rectangles with `GS_EN` and `HS_EN` clear, when polygon mode is disabled or both faces are filled. Points, patches and absent routing or rasterization registers still throw. Bit 16 selects the misc export's X component as PointSize ([AMD CIK register reference](https://www.amd.com/content/dam/amd/en/documents/radeon-tech-docs/programmer-references/CIK_3D_registers_v2.pdf), PA_CL_VS_OUT_CNTL); ignoring it for non-point rasterization follows [Vulkan PointSize](https://docs.vulkan.org/refpages/latest/refpages/source/PointSize.html). This is inferred, not measured on console hardware. XashPS5 (PPSA19111 v1.3) sets `0x01210000` on a filled triangle draw.
 - [Native MSAA depth attachment feedback](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) is not implemented. A draw sampling a native multisampled depth view while attaching its source image throws before pipeline creation or render-pass recording, including read-only attachment feedback. Sampling that image in a separate draw or dispatch remains supported. The refusal compares the held native image views and their device and attachment identity; single-sample depth behavior is retained.
 - [Native multisampled depth sampling](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) accepts numeric D16 or D32, two/four/eight samples, one Z_X slice and mip, and pipe-aligned ITERATE_256 HTILE without stencil or VRS. Sampling eligibility is recorded before the attachment's first host clear: every HTILE word must prove the same initial clear of zero or one, and the complete sample-aware depth and HTILE ranges must be accessible and write-watched. Unsupported initial state or device sampling support retains attachment rendering but sampling throws; eligibility is never retried. Sampling rejects later guest writes, queued external GPU writes, and HTILE clear/fill transitions. Guest publication, arbitrary guest depth import, stencil/raw-bit sampling, arrays, storage access and allocation retirement remain unimplemented. The block footprint follows main's AMD Addrlib thin-block rule; the accepted HTILE clear words and PS5 equivalence are not measured on console hardware. PPSA99902's historical resident eight-sample D32 reader is documented in [#419](https://github.com/boykopovar/AnyPS5/pull/419#issuecomment-6105597729); the subsequent completed HTILE transition needs separate support.

Subject: [PATCH 0265/1000] fix(ngs2): accept empty waveform blocks and matrix
 levels on a voice without a format

A sampler voice set up with an all-zero format has no channels. Adding no
waveform blocks to it, or setting a matrix with no levels, threw
std::invalid_argument, which ends the title.

Accept both on such a voice: the empty add only applies RESET and the
CONTINUE state, and the empty matrix clears that matrix, which rendering
already treats as unset. Blocks with data, APPEND, and an empty matrix on
a voice with a format are still refused.

Steins;Gate Re:Boot (PPSA36591) clears a voice this way when a button is
pressed at its title screen.

 - [NGS2 ATRAC9 streaming](../../../core/libs/prx/libSceNgs2.native/src/Atrac9.cpp) keeps waveform duration and skip counts across compressed input blocks. The shared `APPEND` flag (2), called `ONLY_DATA` in the compressed-data reference, ignores an ATRAC9 continuation block's sample, skip and repeat counts, following [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/bb98f26433fa9e711c219aac1711fe8ecba5bf3a/src/libs/ngs2.cpp); PPSA03747 confirms a 262044-byte initial buffer declaring 11310532 samples, followed by 16384-byte buffers with flags 3. Incomplete superframes are retained until more input arrives. Input-block completion callbacks allow refills; the final callback of a logical waveform waits for its buffered PCM to drain, preserving the existing complete-block repeat behaviour. This buffering, callback timing, decoded-byte accounting and starvation silence are unverified on hardware. A closed ATRAC9 stream ending before its declared samples throws; fragmented ATRAC9 waveforms with repeats are unsupported. PCM streaming retains its existing append validation and early-close behaviour.
 - [NGS2 mastering voice gain](../../../core/libs/prx/libSceNgs2.native/src/Voice.cpp) (libSceNgs2.native) - the param id 0x30000004 is taken from PPSA22520 and the layout from [shadPS4](https://github.com/shadps4-emu/shadPS4)'s `OrbisNgs2MasteringVoiceGainParam`; no reference gives the units or range. The levels are assumed to be linear factors applied when the mastering voice is mixed into the render buffer, so the voice's own samples stay unscaled; the LFE level applies to channel 3 of 6- and 8-channel voices, assuming the L R C LFE order of the AudioOut2 entries above, and the full-band level to the rest. Negative levels are accepted, and a new setup resets both levels to 1
 - [NGS2 stereo mastering voice into a surround buffer](../../../core/libs/prx/libSceNgs2.native/src/Render.cpp) (libSceNgs2.native) - PPSA21402 renders a 2-channel mastering voice into a 6- or 8-channel render buffer, which the mixing stage rejected. The console's conversion is unknown: the left and right channels are assumed to go to the first two buffer channels (front left and right) and the remaining channels stay silent, with no centre, LFE or surround content. Any other channel count mismatch still throws
+- [NGS2 voices without a format](../../../core/libs/prx/libSceNgs2.native/src/Voice.cpp) (libSceNgs2.native) - a sampler voice whose setup has no format (all zero) accepts an add of no waveform blocks without `APPEND`, which only applies `RESET` and the `CONTINUE` state, and matrix levels with no levels, which clear that matrix. PPSA36591 sets such a voice up, adds no blocks and sets no levels when a button is pressed at its title screen. Whether the console returns success or an error there is not measured; blocks with data, `APPEND` and an empty matrix on a voice with a format are still refused
 - [NGS2 silent waveform blocks](../../../core/libs/prx/libSceNgs2.native/src/Voice.cpp) (libSceNgs2.native): flag `0x10` (named `SILENCE` here; no public reference names it) lets a waveform block declare samples without data. PPSA04867 adds one block with flags `0x11`, `data_size` 0 and `num_samples` 16385, then another with flags `0x11` and a fully specified 0x800-byte, 1024-sample mono block, which takes the ordinary path. A dataless block under the flag outputs `num_samples` frames of silence, reports them through `decoded_data_size`, and finishes like a complete block; a dataless block without the flag still throws as not fitting its data. The flag's real name, its interaction with ATRAC9 and repeats, and the console's `waveform_data` for silent blocks are unverified on hardware
 - [NGS2 streaming PCM waveforms](../../../core/libs/prx/libSceNgs2.native/src/Voice.cpp) (libSceNgs2.native) - PPSA21402 streams its music by adding one block whose `num_samples` is the whole track and whose `data_size` is a 16 KiB first piece, with `CONTINUE`, and then adds each following piece with flag `0x2` (called `APPEND` here) and the same `num_samples`. No reference describes flag `0x2`. A 16-bit PCM block without skipped samples or repeats whose `num_samples` exceed its data is assumed to start such a stream; flag `0x2` is assumed to append the block's data to the last streaming block, ignoring its `num_samples`; the voice is assumed to output silence without advancing while it has played all appended data and `CONTINUE` is set; and the waveform is assumed to end at `num_samples` or, once `CONTINUE` is cleared, at the end of the appended data. `sceNgs2VoiceGetState` reports the bytes played as `decoded_data_size`, which the title uses to release its queued data, and the read position as `waveform_data`.

When the console sets and clears EMPTY, and whether it also reports it for other voice types, is unverified on hardware.
 - [NGS2 port matrix](../../../core/libs/prx/libSceNgs2.native/src/Render.cpp) (libSceNgs2.native) - a port without a matrix, or with a selected matrix whose levels were never set, mixes through a default channel map: mono reaches both stereo channels at -3 dB and the 5.1 and 7.1 centre, stereo folds to mono at -3 dB per side, and wider sources fold down with 0.5 and -3 dB gains. The map and the equivalence of an unset matrix with no matrix were measured from the PS4 firmware 11.00 `libSceNgs2.sprx`, not yet from the PS5 library. That library only accepts submixer and mastering voices with 1, 2, 6 or 8 channels, so the map into 3, 4, 5 or 7 channels throws. A matrix set with fewer levels than the destination needs still mixes only the rows it has
 - [NGS2 custom submixer rack](../../../core/libs/prx/libSceNgs2.native/src/Custom.cpp) (libSceNgs2.native, rack 0x4002) - structure layouts from [shadPS4](https://github.com/shadps4-emu/shadPS4)'s `ngs2_custom.h`; module id 0x1f for UserFx2 and 0x1d for UserFx, voice parameter ids `0x40001f00 | module index` and `0x40001d00 | module index`, the process flags (1 on the first process call after setup, 2 after a parameter change, 0 otherwise) and the call order (setup per voice at rack creation, process after the inputs are mixed, cleanup at destruction) come only from [KytyPS5](https://github.com/KytyPS5/KytyPS5) and shadPS4. Only UserFx and UserFx2 modules on a single buffer are accepted: other module ids, more buffers, a module control handler, different input and output channel counts, setup flags and default rack options throw. Each module's state is a separate buffer, not the `state_offset` slice of the voice state, and `sceNgs2VoiceGetState` still throws for this rack. As in KytyPS5, UserFx2 process runs only on grains where an input produced samples, so an effect tail stops with the input and a pending flag 2 waits for the next audible grain

 - [Descriptor pool chain](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - each pool holds two storage buffer descriptors more than a set can take, as a workaround: RADV (Mesa 26.0 and later) lets a `FREE_DESCRIPTOR_SET` pool place a set up to 32 bytes past the pool's buffer ([`util_vma_heap_init`](https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/amd/vulkan/radv_descriptor_pool.c) is given `bo_size + RADV_POOL_HEAP_OFFSET` as a size), and with a page-multiple pool size those bytes are an unmapped page
 - [CMASK fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver) - each fast-cleared CMASK tile (code 0) is stored as `CB_COLOR_CLEAR_WORD` into its 8x8 texels at the first draw into the target or at its fast-clear eliminate or DCC decompress pass, not as the color block writes the tile, and the CMASK is then stored as expanded (0xF): a texture or copy read of the target after that draw and before the title's eliminate sees the clear value in tiles no draw wrote, where the console keeps their previous bytes. Tile addresses follow the pipe-aligned SW_64KB_Z_X CMASK equation for 16 pipes; other CMASK swizzle modes, a cleared tile of a DCC target and a fast clear of a mipmapped (base mip 0), 3D or array color target throw. A tile with a code other than 0 and 0xF keeps its texels like an expanded tile: PPSA18391 (engine: Clickteam Fusion) fast clears a target whose CMASK it never initialized, so some of its nibbles hold leftover values such as 1 and 10; what the console does with such codes on a single-sample target is unverified on hardware. Single-sample views with `viewMip > 0` skip CMASK fast-clear decoding since CMASK metadata only covers base mip 0 on AMD hardware (Mesa `si_state.c` similarly clears `FAST_CLEAR` for level > 0).
 - [HTILE depth fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - HTILE is not modeled. Only RADV's `clear_htile_mask` compute kernel (17 GFX10 words, 64x1x1 groups) is recognized, and only when it leaves ZMASK at 0 (`user[4]` and `user[5]` low nibbles both 0); the dispatch still runs, and the host depth image is cleared to `DB_DEPTH_CLEAR` the next time the surface with that `DB_HTILE_DATA_BASE` address is bound. The address match is exact, so a clear of a different HTILE range does not hit. HTILE initialization, the stencil-only update, and fast clears made by the SDK's own paths, CP DMA fills or other kernels are not covered and leave the depth image as it was. The kernel words are the ones the PR author saw RADV submit; they are not compared with Mesa's source. A second kernel, the 9-word dword fill PPSA01802 (Kena: Bridge of Spirits) clears its depth HTILE with (64x1x1 groups, one `buffer_store_format_x` per thread through the stride-4 V# in `user[0..3]`, the value read by `s_buffer_load_dword` through the V# in `user[4..7]`), is taken as a fill of that range when the store format is 32_UINT, 32_SINT or 32_FLOAT and the value V# covers the dword (NUM_RECORDS times its stride, or NUM_RECORDS bytes when the stride is 0) ([`MatchMemoryValueFill`](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp), then the whole-HTILE and ZMask rules of `NoteDepthMetadataFill`). The value is read from guest memory when the dispatch is decoded, so a value that earlier GPU work in the same submission has not written back yet is not seen. When the [fill HLE](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Memory/BufferFill.cpp) takes the dispatch instead (an output descriptor of one 32-bit value per element, a value descriptor that covers the loaded dword, a 16-byte aligned range), the value is read again when the fill is recorded, after the labels queued before it, and the HTILE fill is noted with that value.
+- [HTILE written by other kernels](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - when a depth target is bound and its HTILE was written since it was last read, the words are read: when every one marks the depth (ZMask 0) or the stencil (SMem 0) cleared, the surface takes that fast clear and the words are stored back as expanded (depth only: ZMask 15 over the full Z range; with stencil: ZMask 15, Z range and SMem, SR1 and SR0 3), so only the title's next clear clears it again. PPSA29141 clears its depth every frame with a compute kernel the fill hooks do not recognize (`InvokeHTileClearComputeShader` in its `ClearMRT` pass); without this its depth kept every earlier frame and moving objects left black trails. The word layouts are Mesa radv's for GFX10. Metadata with some tiles cleared is not modelled, and the compression state draws leave in HTILE is not tracked, so a title reading its HTILE after a draw sees the stored expanded words
 - [Host imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver) on Linux skip ranges that are not mapped read-write, which are copied instead. The NVIDIA driver (595.91.07) refuses `VK_EXT_external_memory_host` imports of read-only or executable mappings (and shared mappings of regular files) with `VK_ERROR_OUT_OF_DEVICE_MEMORY`, after which every `vkAllocateMemory` on the device fails the same way. Read-only ranges are never imported, even on drivers that accept them. Shared mappings of regular files are not checked for. On Windows, an alias of adjacent registered ranges is refused if any page is not a shared view; a range made entirely of shared views is aliased run by run, including across sections or nonconsecutive section offsets. Adjacent registered ranges are joined into one import where they fill a whole 8 MiB aligned window; ranges of a partly filled window, and ranges larger than the window, are imported one at a time. A buffer bound across adjacent ranges that are each larger than the window, or bound exactly over adjacent ranges of any size (from the first one's start to the last one's end), joins them into one import when it is bound, and their own imports are retired; a buffer that crosses any other two imports is copied. A heap grown in pieces re-imports its joined run only when a buffer is bound exactly over all of its pieces, or when a sparse descriptor heap over it is bound: a heap a shader binds whole while only the pieces from its base are mapped is bound in place from the import of that run, its views ending at the import's end as the copy's do, once the previous bind of that address saw the same last mapped byte (a heap that grows between every two of its binds stays copied; one bound more often than it grows is joined again after each growth) and at most 64 times per joined run base; past that, with a message, it is not joined again: it is bound in place while an existing import covers its run and copied otherwise, until no registered range starts at that base or the device changes. Ranges larger than the window are taken to be registered whole and never grown in pieces: a title that grows a heap in pieces larger than 8 MiB re-imports the joined run each time a bound buffer crosses into a new piece. The 8 MiB window is a choice: unbounded runs were re-imported whole on every growth of a heap mapped in small pieces, and the NVIDIA driver (610.57.04, 615.78.08) then refused imports or lost the device. Not measured on RADV.
 - [Cube texture descriptors](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) with equal `BASE_ARRAY` and `DEPTH` expose six faces starting at `BASE_ARRAY`. Measured with `image_load`, `image_sample` and `image_get_resinfo` on RX 6600 (gfx1032), using 64x64 R32_UINT faces and base slices 0, 5 and 6. Other ranges containing fewer than six faces or incomplete cube arrays still throw: hardware load bounds and filtered-sample addressing differ. Out-of-range cube-array sampling remains unimplemented. Samplers with `DISABLE_CUBE_WRAP` are created with `VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT`, the flag RADV maps to that bit (Mesa `src/amd/vulkan/radv_sampler.c`, `src/amd/common/ac_descriptors.c`); without `VK_EXT_non_seamless_cube_map` a cube texture sampled through such a sampler throws. PS5 equivalence has not been measured on console hardware.
 - [Array layer views](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) (libSceAgcDriver) - `ArrayLayersServeView` lets a 2D texture at a 2D array image's base address, or a 2D array texture over its first layers, view that image (`Texture::CanCopyFrom`). Mesa-built homebrew (ps5-opengl) writes the view's last slice plus one to `CB_COLOR_ATTRIB3.MIP0_DEPTH`, so a slice-0 render target is a two-layer array image, and the title samples it as a plain 2D texture (SuperTuxKart PPSA69421 drew a black 3D scene and minimap without this). The per-layer layout of a mipmapped array is assumed equal to a standalone surface's; it is not measured on the console. A 2D texture at a later slice's address still gets an image of its own.

Subject: [PATCH 0269/1000] fix(agc): read and store back the whole
 pipe-aligned HTILE outside the surfaces lock

The bind-time HTILE read covered one word per 8x8 tile from DB_HTILE_DATA_BASE, but main models the
HTILE as the pipe-aligned SW_64KB_Z_X metadata (HtileMetadataBytes, the extent HtileFillCovers takes):
at 1920x1080, 1856 of the 32400 tile words lie past the first tiles*4 bytes, so they kept ZMask 0
after a store-back. The read and the store-back now cover the whole metadata and run before the
surfaces mutex is taken, since both wait for recorded work over the range. The tests' HTILE arrays
hold the whole metadata.

PPSA25344 (Unreal Engine 5) decodes its depth through HTILE in its Nanite depth export after the
depth prepass and takes ZMask 0 as a tile holding the clear value; the new
agc_driver_depth_fast_clear_submit case checks that a draw after a fast clear leaves every word
expanded.

 - [CMASK fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver) - each fast-cleared CMASK tile (code 0) is stored as `CB_COLOR_CLEAR_WORD` into its 8x8 texels at the first draw into the target or at its fast-clear eliminate or DCC decompress pass, not as the color block writes the tile, and the CMASK is then stored as expanded (0xF): a texture or copy read of the target after that draw and before the title's eliminate sees the clear value in tiles no draw wrote, where the console keeps their previous bytes. Tile addresses follow the pipe-aligned SW_64KB_Z_X CMASK equation for 16 pipes; other CMASK swizzle modes, a cleared tile of a DCC target and a fast clear of a mipmapped (base mip 0), 3D or array color target throw. A tile with a code other than 0 and 0xF keeps its texels like an expanded tile: PPSA18391 (engine: Clickteam Fusion) fast clears a target whose CMASK it never initialized, so some of its nibbles hold leftover values such as 1 and 10; what the console does with such codes on a single-sample target is unverified on hardware. Single-sample views with `viewMip > 0` skip CMASK fast-clear decoding since CMASK metadata only covers base mip 0 on AMD hardware (Mesa `si_state.c` similarly clears `FAST_CLEAR` for level > 0).
 - [HTILE depth fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - HTILE is not modeled. Only RADV's `clear_htile_mask` compute kernel (17 GFX10 words, 64x1x1 groups) is recognized, and only when it leaves ZMASK at 0 (`user[4]` and `user[5]` low nibbles both 0); the dispatch still runs, and the host depth image is cleared to `DB_DEPTH_CLEAR` the next time the surface with that `DB_HTILE_DATA_BASE` address is bound. The address match is exact, so a clear of a different HTILE range does not hit. HTILE initialization, the stencil-only update, and fast clears made by the SDK's own paths, CP DMA fills or other kernels are not covered and leave the depth image as it was. The kernel words are the ones the PR author saw RADV submit; they are not compared with Mesa's source. A second kernel, the 9-word dword fill PPSA01802 (Kena: Bridge of Spirits) clears its depth HTILE with (64x1x1 groups, one `buffer_store_format_x` per thread through the stride-4 V# in `user[0..3]`, the value read by `s_buffer_load_dword` through the V# in `user[4..7]`), is taken as a fill of that range when the store format is 32_UINT, 32_SINT or 32_FLOAT and the value V# covers the dword (NUM_RECORDS times its stride, or NUM_RECORDS bytes when the stride is 0) ([`MatchMemoryValueFill`](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp), then the whole-HTILE and ZMask rules of `NoteDepthMetadataFill`). The value is read from guest memory when the dispatch is decoded, so a value that earlier GPU work in the same submission has not written back yet is not seen. When the [fill HLE](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Memory/BufferFill.cpp) takes the dispatch instead (an output descriptor of one 32-bit value per element, a value descriptor that covers the loaded dword, a 16-byte aligned range), the value is read again when the fill is recorded, after the labels queued before it, and the HTILE fill is noted with that value.

The NVIDIA driver (595.91.07) refuses `VK_EXT_external_memory_host` imports of read-only or executable mappings (and shared mappings of regular files) with `VK_ERROR_OUT_OF_DEVICE_MEMORY`, after which every `vkAllocateMemory` on the device fails the same way. Read-only ranges are never imported, even on drivers that accept them. Shared mappings of regular files are not checked for.

Adjacent registered ranges are joined into one import where they fill a whole 8 MiB aligned window; ranges of a partly filled window, and ranges larger than the window, are imported one at a time. A buffer bound across adjacent ranges that are each larger than the window, or bound exactly over adjacent ranges of any size (from the first one's start to the last one's end), joins them into one import when it is bound, and their own imports are retired; a buffer that crosses any other two imports is copied. A heap grown in pieces re-imports its joined run only when a buffer is bound exactly over all of its pieces, or when a sparse descriptor heap over it is bound: a heap a shader binds whole while only the pieces from its base are mapped is bound in place from the import of that run, its views ending at the import's end as the copy's do, once the previous bind of that address saw the same last mapped byte (a heap that grows between every two of its binds stays copied; one bound more often than it grows is joined again after each growth) and at most 64 times per joined run base; past that, with a message, it is not joined again: it is bound in place while an existing import covers its run and copied otherwise, until no registered range starts at that base or the device changes. Ranges larger than the window are taken to be registered whole and never grown in pieces: a title that grows a heap in pieces larger than 8 MiB re-imports the joined run each time a bound buffer crosses into a new piece. The 8 MiB window is a choice: unbounded runs were re-imported whole on every growth of a heap mapped in small pieces, and the NVIDIA driver (610.57.04, 615.78.08) then refused imports or lost the device. Not measured on RADV.
 - [Cube texture descriptors](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) with equal `BASE_ARRAY` and `DEPTH` expose six faces starting at `BASE_ARRAY`. Measured with `image_load`, `image_sample` and `image_get_resinfo` on RX 6600 (gfx1032), using 64x64 R32_UINT faces and base slices 0, 5 and 6. Other ranges containing fewer than six faces or incomplete cube arrays still throw: hardware load bounds and filtered-sample addressing differ. Out-of-range cube-array sampling remains unimplemented. Samplers with `DISABLE_CUBE_WRAP` are created with `VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT`, the flag RADV maps to that bit (Mesa `src/amd/vulkan/radv_sampler.c`, `src/amd/common/ac_descriptors.c`); without `VK_EXT_non_seamless_cube_map` a cube texture sampled through such a sampler throws. PS5 equivalence has not been measured on console hardware.
 - [Array layer views](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) (libSceAgcDriver) - `ArrayLayersServeView` lets a 2D texture at a 2D array image's base address, or a 2D array texture over its first layers, view that image (`Texture::CanCopyFrom`). Mesa-built homebrew (ps5-opengl) writes the view's last slice plus one to `CB_COLOR_ATTRIB3.MIP0_DEPTH`, so a slice-0 render target is a two-layer array image, and the title samples it as a plain 2D texture (SuperTuxKart PPSA69421 drew a black 3D scene and minimap without this). The per-layer layout of a mipmapped array is assumed equal to a standalone surface's; it is not measured on the console. A 2D texture at a later slice's address still gets an image of its own.

Subject: [PATCH 0270/1000] fix(agc): take a slice of a depth array from its
 own HTILE only when its words are uniform

A fill or clear the driver recognizes over an HTILE drops the range's last-read generation, so the
next bind reads the words and stores them back even when the write tracker did not see the fill's
stores. A depth view of slice 1 or later reads the HTILE at its own address
(DB_HTILE_DATA_BASE + slice * HtileMetadataBytes); the HTILE word layout is only modelled for slice 0,
so such a slice takes the clear and the store-back only when all its words are equal and keeps its
fill-time fast clears otherwise. DepthTarget::slice carries DB_DEPTH_VIEW SLICE_START.

agc_driver_depth_fast_clear_submit: an unrecognized kernel clears the HTILE on two frames in a row and
both clears are taken; slice 1 with words that are not all equal is refused and stored back untouched;
slice 1 with equal words takes the clear. agc_driver_graphics checks the decoded slice.

 - [Descriptor pool chain](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - each pool holds two storage buffer descriptors more than a set can take, as a workaround: RADV (Mesa 26.0 and later) lets a `FREE_DESCRIPTOR_SET` pool place a set up to 32 bytes past the pool's buffer ([`util_vma_heap_init`](https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/amd/vulkan/radv_descriptor_pool.c) is given `bo_size + RADV_POOL_HEAP_OFFSET` as a size), and with a page-multiple pool size those bytes are an unmapped page
 - [CMASK fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver) - each fast-cleared CMASK tile (code 0) is stored as `CB_COLOR_CLEAR_WORD` into its 8x8 texels at the first draw into the target or at its fast-clear eliminate or DCC decompress pass, not as the color block writes the tile, and the CMASK is then stored as expanded (0xF): a texture or copy read of the target after that draw and before the title's eliminate sees the clear value in tiles no draw wrote, where the console keeps their previous bytes. Tile addresses follow the pipe-aligned SW_64KB_Z_X CMASK equation for 16 pipes; other CMASK swizzle modes, a cleared tile of a DCC target and a fast clear of a mipmapped (base mip 0), 3D or array color target throw. A tile with a code other than 0 and 0xF keeps its texels like an expanded tile: PPSA18391 (engine: Clickteam Fusion) fast clears a target whose CMASK it never initialized, so some of its nibbles hold leftover values such as 1 and 10; what the console does with such codes on a single-sample target is unverified on hardware. Single-sample views with `viewMip > 0` skip CMASK fast-clear decoding since CMASK metadata only covers base mip 0 on AMD hardware (Mesa `si_state.c` similarly clears `FAST_CLEAR` for level > 0).
 - [HTILE depth fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - HTILE is not modeled. Only RADV's `clear_htile_mask` compute kernel (17 GFX10 words, 64x1x1 groups) is recognized, and only when it leaves ZMASK at 0 (`user[4]` and `user[5]` low nibbles both 0); the dispatch still runs, and the host depth image is cleared to `DB_DEPTH_CLEAR` the next time the surface with that `DB_HTILE_DATA_BASE` address is bound. The address match is exact, so a clear of a different HTILE range does not hit. HTILE initialization, the stencil-only update, and fast clears made by the SDK's own paths, CP DMA fills or other kernels are not covered and leave the depth image as it was. The kernel words are the ones the PR author saw RADV submit; they are not compared with Mesa's source. A second kernel, the 9-word dword fill PPSA01802 (Kena: Bridge of Spirits) clears its depth HTILE with (64x1x1 groups, one `buffer_store_format_x` per thread through the stride-4 V# in `user[0..3]`, the value read by `s_buffer_load_dword` through the V# in `user[4..7]`), is taken as a fill of that range when the store format is 32_UINT, 32_SINT or 32_FLOAT and the value V# covers the dword (NUM_RECORDS times its stride, or NUM_RECORDS bytes when the stride is 0) ([`MatchMemoryValueFill`](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp), then the whole-HTILE and ZMask rules of `NoteDepthMetadataFill`). The value is read from guest memory when the dispatch is decoded, so a value that earlier GPU work in the same submission has not written back yet is not seen. When the [fill HLE](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Memory/BufferFill.cpp) takes the dispatch instead (an output descriptor of one 32-bit value per element, a value descriptor that covers the loaded dword, a 16-byte aligned range), the value is read again when the fill is recorded, after the labels queued before it, and the HTILE fill is noted with that value.
-- [HTILE written by other kernels](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - when a depth target is bound and its HTILE was written since it was last read, the words over its whole pipe-aligned metadata (`HtileMetadataBytes`, the extent `HtileFillCovers` takes) are read, outside the surfaces mutex since the read waits for recorded work: when every one marks the depth (ZMask 0) or the stencil (SMem 0) cleared, the surface takes that fast clear and the words are stored back as expanded (depth only: ZMask 15 over the full Z range; with stencil: ZMask 15, Z range and SMem, SR1 and SR0 3), so only the title's next clear clears it again. PPSA29141 clears its depth every frame with a compute kernel the fill hooks do not recognize (`InvokeHTileClearComputeShader` in its `ClearMRT` pass); without this its depth kept every earlier frame and moving objects left black trails. PPSA25344 (Unreal Engine 5) reads its HTILE after the depth prepass in its Nanite depth export, which takes a tile with ZMask 0 as holding the clear value; without the expanded words the export put Nanite depth over the prepass and the Nanite material pass painted over the meshes in front.

A slice other than 0 of a depth array is read at its own HTILE (`DB_HTILE_DATA_BASE` plus the slice times `HtileMetadataBytes`) but the HTILE word layout of slices 1 and up is not modelled (PPSA05684's tile masks need X8 and Y8 to take Z0 and Z1 as well, slices 4 and up unmeasured), so such a slice takes the clear only when all its words are equal and otherwise keeps the fill-time fast clears. A depth-only HTILE whose tiles all have ZMask 0 but different Min/Max Z (per-tile clear values, PPSA05684's cascades) is taken as a whole-surface clear to `DB_DEPTH_CLEAR`.
 - [Host imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver) on Linux skip ranges that are not mapped read-write, which are copied instead. The NVIDIA driver (595.91.07) refuses `VK_EXT_external_memory_host` imports of read-only or executable mappings (and shared mappings of regular files) with `VK_ERROR_OUT_OF_DEVICE_MEMORY`, after which every `vkAllocateMemory` on the device fails the same way. Read-only ranges are never imported, even on drivers that accept them. Shared mappings of regular files are not checked for. On Windows, an alias of adjacent registered ranges is refused if any page is not a shared view; a range made entirely of shared views is aliased run by run, including across sections or nonconsecutive section offsets. Adjacent registered ranges are joined into one import where they fill a whole 8 MiB aligned window; ranges of a partly filled window, and ranges larger than the window, are imported one at a time. A buffer bound across adjacent ranges that are each larger than the window, or bound exactly over adjacent ranges of any size (from the first one's start to the last one's end), joins them into one import when it is bound, and their own imports are retired; a buffer that crosses any other two imports is copied. A heap grown in pieces re-imports its joined run only when a buffer is bound exactly over all of its pieces, or when a sparse descriptor heap over it is bound: a heap a shader binds whole while only the pieces from its base are mapped is bound in place from the import of that run, its views ending at the import's end as the copy's do, once the previous bind of that address saw the same last mapped byte (a heap that grows between every two of its binds stays copied; one bound more often than it grows is joined again after each growth) and at most 64 times per joined run base; past that, with a message, it is not joined again: it is bound in place while an existing import covers its run and copied otherwise, until no registered range starts at that base or the device changes. Ranges larger than the window are taken to be registered whole and never grown in pieces: a title that grows a heap in pieces larger than 8 MiB re-imports the joined run each time a bound buffer crosses into a new piece. The 8 MiB window is a choice: unbounded runs were re-imported whole on every growth of a heap mapped in small pieces, and the NVIDIA driver (610.57.04, 615.78.08) then refused imports or lost the device. Not measured on RADV.
 - [Cube texture descriptors](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) with equal `BASE_ARRAY` and `DEPTH` expose six faces starting at `BASE_ARRAY`. Measured with `image_load`, `image_sample` and `image_get_resinfo` on RX 6600 (gfx1032), using 64x64 R32_UINT faces and base slices 0, 5 and 6. Other ranges containing fewer than six faces or incomplete cube arrays still throw: hardware load bounds and filtered-sample addressing differ. Out-of-range cube-array sampling remains unimplemented. Samplers with `DISABLE_CUBE_WRAP` are created with `VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT`, the flag RADV maps to that bit (Mesa `src/amd/vulkan/radv_sampler.c`, `src/amd/common/ac_descriptors.c`); without `VK_EXT_non_seamless_cube_map` a cube texture sampled through such a sampler throws. PS5 equivalence has not been measured on console hardware.
 - [Array layer views](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) (libSceAgcDriver) - `ArrayLayersServeView` lets a 2D texture at a 2D array image's base address, or a 2D array texture over its first layers, view that image (`Texture::CanCopyFrom`). Mesa-built homebrew (ps5-opengl) writes the view's last slice plus one to `CB_COLOR_ATTRIB3.MIP0_DEPTH`, so a slice-0 render target is a two-layer array image, and the title samples it as a plain 2D texture (SuperTuxKart PPSA69421 drew a black 3D scene and minimap without this). The per-layer layout of a mipmapped array is assumed equal to a standalone surface's; it is not measured on the console. A 2D texture at a later slice's address still gets an image of its own.

 - [mincore](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) follows FreeBSD 11's `sys_mincore` (`sys/vm/vm_mmap.c`), not measured on the console: the address is rounded down to the page, length 0 returns 0, a null vector over a mapped range returns `EFAULT`, an overflowing range or any unmapped page in the range (as reported by `sceKernelVirtualQuery`) returns `ENOMEM`. For valid ranges, a page reports `MINCORE_INCORE` (0x1) when `sceKernelVirtualQuery` reports it committed and 0 when it is only reserved; actual residency, referenced and modified bits are not modelled. Length 0 returns 0 when the start page is mapped and `ENOMEM` otherwise, and the range and mapping checks come before the null vector `EFAULT`, as in `kern_mincore` Java 25 LAN / DNS (PPSA99869) imports it
 - [mlockall](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) returns `EINVAL` for zero or unknown flags. Valid `MCL_CURRENT` throws because it would lock host stacks, heaps, modules and driver mappings along with guest memory; `MCL_FUTURE` throws because later mappings are not tracked for locking. On main, XPSemu (PPSA97358) fails to load at this import; its `MCL_CURRENT | MCL_FUTURE` calls execute only when `-overcommit mem-lock=on` is enabled. The call has not been observed in a run with this implementation.
 - [sigtimedwait](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) waits on a process-wide pending set instead of throwing: a signal raised while blocked stays pending and is taken by `sigwait`, `sigwaitinfo` or `sigtimedwait`, delivered to the handler when `_sigprocmask` unblocks it, or delivered by `pause`. The set covers all 128 signals and the lowest number that is pending and in the set is selected (FreeBSD specifies the lowest number only among real-time signals). Selection, `EAGAIN` on timeout, `EINVAL` for a `tv_nsec` outside 0 to 1000000000 while nothing is pending and `NULL` timeout blocking indefinitely follow FreeBSD's [sigtimedwait(2)](https://man.freebsd.org/cgi/man.cgi?query=sigtimedwait). `sigwait` returns 0 with the number in its output, as POSIX specifies, and `sigwaitinfo` and `sigtimedwait` return the number, as FreeBSD does. The guest `siginfo_t` follows FreeBSD 11's `sys/sys/siginfo.h`: 80 bytes, `si_signo` at 0, `si_code` at 8, `si_pid` at 12, `si_uid` at 16, `si_addr` at 24, `si_value` at 32 and `si_band` at 40; only `si_signo`, `si_code` (`SI_USER`) and `si_pid` (the guest pid) are written, `si_uid` stays 0 because no uid is modelled, and the console's layout is not verified. PPSA85300 imports `sigtimedwait` and fails to load without it; its only call site is VLC's `vlc_writev` ([filesystem.c](https://github.com/videolan/vlc/blob/6de05adcbaf2e8b85fe86aad4169393098628119/src/posix/filesystem.c#L243-L278)), which polls with a zero timeout to drain a `SIGPIPE` only after `writev` fails with `EPIPE`. The waits are not cancellation points and an unblocked caught signal does not interrupt them with `EINTR`, where FreeBSD's `sigwaitinfo` and `sigtimedwait` may return it. `SIGPIPE` has no host equivalent and is never raised by a host write here (see `read, write and vector I/O`), so VLC's drain finds nothing

A signal whose registered handler has `SA_SIGINFO` still throws, and one whose disposition is the default action and that has no host equivalent (every signal except 2, 4, 6, 8, 11 and 15) is neither delivered nor discarded: it stays pending until a wait takes it, where FreeBSD runs the default action, which terminates the process for most of them.

Only handlers without `SA_SIGINFO` on the signals `signal` already delivers (`SIGINT`, `SIGILL`, `SIGABRT`, `SIGFPE`, `SIGSEGV`, `SIGTERM`) run, the same way `signal` handlers do; their mask and flags are not applied. `SA_SIGINFO` handlers are recorded but never called, since that needs FreeBSD's `siginfo_t` and `ucontext_t`, and neither are the handlers of other signals (`SIGBUS`, `SIGHUP`, ...), whether they are set by `sigaction` or by `signal`, which records them too (every number from 1 to 128, with `SA_RESTART` and an empty mask replacing what `sigaction` stored; `SIGKILL` and `SIGSTOP` accept only the default handler in both calls, as in FreeBSD's `kern_sigaction`). `raise` and `kill` accept every number from 1 to 128 now: a blocked one stays pending on the set of `sigtimedwait`, an unblocked one whose handler is registered runs it on the calling thread, and an unblocked one that has no host equivalent and no handler still fails with `EINVAL`, where FreeBSD runs its default action. `raise` of an `SA_SIGINFO` handler still throws instead of terminating
 - [kill, killpg](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) follow FreeBSD's `kern_kill` and `killpg1` for the only guest process: `EINVAL` for signals outside 0 to 128 and for negative `killpg` process groups, signal 0 only checks that the target exists, and its own pid, 0 and minus its own pid (the guest is taken to lead its own process group) signal it through `raise`, so they share `raise`'s limits above. Any other pid, and -1, which skips the caller, report `ESRCH`, so `EPERM` is never reported

Subject: [PATCH 0272/1000] fix(agc): route native-owned depth binds before the
 HTILE read and store-back

A multisampled depth target is created as, or already is, the native depth owner, and a target whose HTILE overlaps a resident depth guard aliases one. Neither may have its HTILE read or rewritten by the generic store-back: the expanded words would be a guest write over the owner's range. DepthSurfaceView decides this before the store-back, which still runs before GpuMutex() and the surfaces mutex are taken. NativeMultisampleDepth binds the owner and a single-sample alias of its HTILE and checks the words stay untouched.

 - [CMASK fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver) - each fast-cleared CMASK tile (code 0) is stored as `CB_COLOR_CLEAR_WORD` into its 8x8 texels at the first draw into the target or at its fast-clear eliminate or DCC decompress pass, not as the color block writes the tile, and the CMASK is then stored as expanded (0xF): a texture or copy read of the target after that draw and before the title's eliminate sees the clear value in tiles no draw wrote, where the console keeps their previous bytes. Tile addresses follow the pipe-aligned SW_64KB_Z_X CMASK equation for 16 pipes; other CMASK swizzle modes, a cleared tile of a DCC target and a fast clear of a mipmapped (base mip 0), 3D or array color target throw. A tile with a code other than 0 and 0xF keeps its texels like an expanded tile: PPSA18391 (engine: Clickteam Fusion) fast clears a target whose CMASK it never initialized, so some of its nibbles hold leftover values such as 1 and 10; what the console does with such codes on a single-sample target is unverified on hardware. Single-sample views with `viewMip > 0` skip CMASK fast-clear decoding since CMASK metadata only covers base mip 0 on AMD hardware (Mesa `si_state.c` similarly clears `FAST_CLEAR` for level > 0).
 - [HTILE depth fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - HTILE is not modeled. Only RADV's `clear_htile_mask` compute kernel (17 GFX10 words, 64x1x1 groups) is recognized, and only when it leaves ZMASK at 0 (`user[4]` and `user[5]` low nibbles both 0); the dispatch still runs, and the host depth image is cleared to `DB_DEPTH_CLEAR` the next time the surface with that `DB_HTILE_DATA_BASE` address is bound. The address match is exact, so a clear of a different HTILE range does not hit. HTILE initialization, the stencil-only update, and fast clears made by the SDK's own paths, CP DMA fills or other kernels are not covered and leave the depth image as it was. The kernel words are the ones the PR author saw RADV submit; they are not compared with Mesa's source. A second kernel, the 9-word dword fill PPSA01802 (Kena: Bridge of Spirits) clears its depth HTILE with (64x1x1 groups, one `buffer_store_format_x` per thread through the stride-4 V# in `user[0..3]`, the value read by `s_buffer_load_dword` through the V# in `user[4..7]`), is taken as a fill of that range when the store format is 32_UINT, 32_SINT or 32_FLOAT and the value V# covers the dword (NUM_RECORDS times its stride, or NUM_RECORDS bytes when the stride is 0) ([`MatchMemoryValueFill`](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp), then the whole-HTILE and ZMask rules of `NoteDepthMetadataFill`). The value is read from guest memory when the dispatch is decoded, so a value that earlier GPU work in the same submission has not written back yet is not seen. When the [fill HLE](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Memory/BufferFill.cpp) takes the dispatch instead (an output descriptor of one 32-bit value per element, a value descriptor that covers the loaded dword, a 16-byte aligned range), the value is read again when the fill is recorded, after the labels queued before it, and the HTILE fill is noted with that value.
-- [HTILE written by other kernels](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - when a depth target is bound and its HTILE was written since it was last read, the words over its whole pipe-aligned metadata (`HtileMetadataBytes`, the extent `HtileFillCovers` takes) are read, outside the surfaces mutex since the read waits for recorded work: when every one marks the depth (ZMask 0) or the stencil (SMem 0) cleared, the surface takes that fast clear and the words are stored back as expanded (depth only: ZMask 15 over the full Z range; with stencil: ZMask 15, Z range and SMem, SR1 and SR0 3), so only the title's next clear clears it again. PPSA29141 clears its depth every frame with a compute kernel the fill hooks do not recognize (`InvokeHTileClearComputeShader` in its `ClearMRT` pass); without this its depth kept every earlier frame and moving objects left black trails. PPSA25344 (Unreal Engine 5) reads its HTILE after the depth prepass in its Nanite depth export, which takes a tile with ZMask 0 as holding the clear value; without the expanded words the export put Nanite depth over the prepass and the Nanite material pass painted over the meshes in front. The word layouts are Mesa radv's for GFX10. Metadata with some tiles cleared is not modelled, and the compression state draws leave in HTILE is not tracked, so a title reading its HTILE after a draw sees the stored expanded words. A recognized HTILE fill or clear makes the next bind read the words again. A slice other than 0 of a depth array is read at its own HTILE (`DB_HTILE_DATA_BASE` plus the slice times `HtileMetadataBytes`) but the HTILE word layout of slices 1 and up is not modelled (PPSA05684's tile masks need X8 and Y8 to take Z0 and Z1 as well, slices 4 and up unmeasured), so such a slice takes the clear only when all its words are equal and otherwise keeps the fill-time fast clears. A depth-only HTILE whose tiles all have ZMask 0 but different Min/Max Z (per-tile clear values, PPSA05684's cascades) is taken as a whole-surface clear to `DB_DEPTH_CLEAR`.

A multisampled depth target, and any target whose HTILE overlaps a resident native depth guard, skips this read and store-back and goes to the native multisample depth owner, which keeps its own refusal for a fast-clear transition.
 - [Host imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver) on Linux skip ranges that are not mapped read-write, which are copied instead. The NVIDIA driver (595.91.07) refuses `VK_EXT_external_memory_host` imports of read-only or executable mappings (and shared mappings of regular files) with `VK_ERROR_OUT_OF_DEVICE_MEMORY`, after which every `vkAllocateMemory` on the device fails the same way. Read-only ranges are never imported, even on drivers that accept them. Shared mappings of regular files are not checked for. On Windows, an alias of adjacent registered ranges is refused if any page is not a shared view; a range made entirely of shared views is aliased run by run, including across sections or nonconsecutive section offsets. Adjacent registered ranges are joined into one import where they fill a whole 8 MiB aligned window; ranges of a partly filled window, and ranges larger than the window, are imported one at a time. A buffer bound across adjacent ranges that are each larger than the window, or bound exactly over adjacent ranges of any size (from the first one's start to the last one's end), joins them into one import when it is bound, and their own imports are retired; a buffer that crosses any other two imports is copied. A heap grown in pieces re-imports its joined run only when a buffer is bound exactly over all of its pieces, or when a sparse descriptor heap over it is bound: a heap a shader binds whole while only the pieces from its base are mapped is bound in place from the import of that run, its views ending at the import's end as the copy's do, once the previous bind of that address saw the same last mapped byte (a heap that grows between every two of its binds stays copied; one bound more often than it grows is joined again after each growth) and at most 64 times per joined run base; past that, with a message, it is not joined again: it is bound in place while an existing import covers its run and copied otherwise, until no registered range starts at that base or the device changes. Ranges larger than the window are taken to be registered whole and never grown in pieces: a title that grows a heap in pieces larger than 8 MiB re-imports the joined run each time a bound buffer crosses into a new piece. The 8 MiB window is a choice: unbounded runs were re-imported whole on every growth of a heap mapped in small pieces, and the NVIDIA driver (610.57.04, 615.78.08) then refused imports or lost the device. Not measured on RADV.
 - [Cube texture descriptors](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) with equal `BASE_ARRAY` and `DEPTH` expose six faces starting at `BASE_ARRAY`. Measured with `image_load`, `image_sample` and `image_get_resinfo` on RX 6600 (gfx1032), using 64x64 R32_UINT faces and base slices 0, 5 and 6. Other ranges containing fewer than six faces or incomplete cube arrays still throw: hardware load bounds and filtered-sample addressing differ. Out-of-range cube-array sampling remains unimplemented. Samplers with `DISABLE_CUBE_WRAP` are created with `VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT`, the flag RADV maps to that bit (Mesa `src/amd/vulkan/radv_sampler.c`, `src/amd/common/ac_descriptors.c`); without `VK_EXT_non_seamless_cube_map` a cube texture sampled through such a sampler throws. PS5 equivalence has not been measured on console hardware.
 - [Array layer views](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) (libSceAgcDriver) - `ArrayLayersServeView` lets a 2D texture at a 2D array image's base address, or a 2D array texture over its first layers, view that image (`Texture::CanCopyFrom`). Mesa-built homebrew (ps5-opengl) writes the view's last slice plus one to `CB_COLOR_ATTRIB3.MIP0_DEPTH`, so a slice-0 render target is a two-layer array image, and the title samples it as a plain 2D texture (SuperTuxKart PPSA69421 drew a black 3D scene and minimap without this). The per-layer layout of a mipmapped array is assumed equal to a standalone surface's; it is not measured on the console. A 2D texture at a later slice's address still gets an image of its own.

Subject: [PATCH 0273/1000] docs(agc): record the BMP open failure measured on
 presentation

VideoOut flips on an RTX 3060 now show that a first frame dump that cannot be opened no longer stops presentation. Header, pixel and close failures remain measured only by the CPU fixture.

An open, header, pixel or close failure prints one diagnostic and disables subsequent BMP dumps for the process; queued frames drain without more file I/O. Pixel validation and allocation failures retain the existing fatal path. The CPU fixture checks identical BMP bytes and real pipe failures; hardware presentation after a storage error is unmeasured.

 - [Inactive vertex point size](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) - `PA_CL_VS_OUT_CNTL.USE_VTX_POINT_SIZE` is accepted for lines, triangles and rectangles with `GS_EN` and `HS_EN` clear, when polygon mode is disabled or both faces are filled. Points, patches and absent routing or rasterization registers still throw. Bit 16 selects the misc export's X component as PointSize ([AMD CIK register reference](https://www.amd.com/content/dam/amd/en/documents/radeon-tech-docs/programmer-references/CIK_3D_registers_v2.pdf), PA_CL_VS_OUT_CNTL); ignoring it for non-point rasterization follows [Vulkan PointSize](https://docs.vulkan.org/refpages/latest/refpages/source/PointSize.html). This is inferred, not measured on console hardware. XashPS5 (PPSA19111 v1.3) sets `0x01210000` on a filled triangle draw.
 - [Native MSAA depth attachment feedback](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) is not implemented. A draw sampling a native multisampled depth view while attaching its source image throws before pipeline creation or render-pass recording, including read-only attachment feedback. Sampling that image in a separate draw or dispatch remains supported. The refusal compares the held native image views and their device and attachment identity; single-sample depth behavior is retained.

 ### Unknown function info
 
 - [Inactive vertex point size](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) - `PA_CL_VS_OUT_CNTL.USE_VTX_POINT_SIZE` is accepted for lines, triangles and rectangles with `GS_EN` and `HS_EN` clear, when polygon mode is disabled or both faces are filled. Points, patches and absent routing or rasterization registers still throw. Bit 16 selects the misc export's X component as PointSize ([AMD CIK register reference](https://www.amd.com/content/dam/amd/en/documents/radeon-tech-docs/programmer-references/CIK_3D_registers_v2.pdf), PA_CL_VS_OUT_CNTL); ignoring it for non-point rasterization follows [Vulkan PointSize](https://docs.vulkan.org/refpages/latest/refpages/source/PointSize.html). This is inferred, not measured on console hardware. XashPS5 (PPSA19111 v1.3) sets `0x01210000` on a filled triangle draw.
+- [Native multisampled depth clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) accept the recognized HTILE mask kernel's direct full-range dispatch after its GPU writes complete. Every metadata byte needs tracked driver-store coverage since notification, no intervening CPU or depth write, and HTILE words proving the current clear value of zero or one. Partial, overlapping, indirect and unproven producers remain unsupported. Existing sampled views retain the native image; guest depth publication and metadata-fill transitions remain unimplemented. Windows shared imports retain write tracking through separate aliases; private host imports that lose tracking and copied or mirrored HTILE uploads remain unsupported. Clear-word encoding and console equivalence remain unmeasured on PS5 hardware.
 - [Native depth allocation retirement](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) covers sampling-eligible multisampled owners only. Successful release notifications must cumulatively cover both complete depth and HTILE ranges; protection changes, failed releases and partial coverage keep the original guards. Retired owners leave lookup and metadata routing, while held views and recorded work retain their images. Retirement of single-sample or sampling-ineligible depth attachments and console equivalence remain unimplemented or unmeasured. The regression uses real allocation-registry operations with a no-op host-release callback, so it does not validate the host unmap backend.
 - [Native MSAA depth attachment feedback](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) is not implemented. A draw sampling a native multisampled depth view while attaching its source image throws before pipeline creation or render-pass recording, including read-only attachment feedback. Sampling that image in a separate draw or dispatch remains supported. The refusal compares the held native image views and their device and attachment identity; single-sample depth behavior is retained.
-- [Native multisampled depth sampling](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) accepts numeric D16 or D32, two/four/eight samples, one Z_X slice and mip, and pipe-aligned ITERATE_256 HTILE without stencil or VRS. Sampling eligibility is recorded before the attachment's first host clear: every HTILE word must prove the same initial clear of zero or one, and the complete sample-aware depth and HTILE ranges must be accessible and write-watched. Unsupported initial state or device sampling support retains attachment rendering but sampling throws; eligibility is never retried. Sampling rejects later guest writes, queued external GPU writes, and HTILE clear/fill transitions. Guest publication, arbitrary guest depth import, stencil/raw-bit sampling, arrays and storage access remain unimplemented. The block footprint follows main's AMD Addrlib thin-block rule; the accepted HTILE clear words and PS5 equivalence are not measured on console hardware. PPSA99902's historical resident eight-sample D32 reader is documented in [#419](https://github.com/boykopovar/AnyPS5/pull/419#issuecomment-6105597729); the subsequent completed HTILE transition needs separate support.

The parameters (a 32-bit mode or frequency, a mode output, a configuration pointer) follow OpenAGC and are never read. Whether later retail firmware enables submit validation or shader debugging is unverified; no title in this repository is known to call them
 - [Indices far past every vertex fetch](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver) - when a draw's highest index is at least 64Ki vertices past the largest per-vertex record count, every index past that count is moved to it in a copy of the indices, so the zero-padded vertex copies are not sized to the original index (PPSA04159 draws a list of `0xffffffff` with primitive restart off, which asked for 160 GiB). Each attribute fetched by vertex index reads zeros there as at the original index (out-of-bounds select 0 or 1); a draw with another out-of-bounds select keeps its indices. The vertex index the shader sees changes for the moved indices, which a shader that reads it directly would notice
 - [Depth clear draws](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - a draw with `DB_RENDER_CONTROL.DEPTH_CLEAR_ENABLE` is taken to write `DB_DEPTH_CLEAR` to every pixel it covers whatever the depth test, depth bounds and depth bias say: it is drawn with an always-passing depth write and the viewport depth range pinned to the clear value. The draw is rasterized as submitted, so its coverage is the draw's own. Whether the DB still applies the depth test or HiZ to such a draw is not measured

 - [chflags](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) follows FreeBSD 11.4's [`kern_chflagsat`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/vfs_syscalls.c#L2366-L2383) and UFS's [`ufs_setattr`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/ufs/ufs/ufs_vnops.c#L509-L556) for a root caller: the path lookup reports `EFAULT`, `ENOENT` and `ENOTDIR`, a flag outside the 17 UFS stores (`VNOVAL` included) `EOPNOTSUPP`, and `SF_SNAPSHOT` `EPERM`. Neither host keeps BSD file flags, so every file is taken to have none (`stat` reports `st_flags` 0): flags 0 succeed without touching the file, and any other flag throws, naming the flags. `UF_READONLY`, `UF_HIDDEN`, `UF_SYSTEM` and `UF_ARCHIVE` are FreeBSD's names for the Windows attributes but are not mapped to them: UFS stores them without enforcing them, `FILE_ATTRIBUTE_READONLY` already carries the owner write bit of `chmod` on Windows, and Linux has no equivalent a process can set without `CAP_LINUX_IMMUTABLE`. The console's filesystem types, `EROFS` on read-only mounts and the change-time update are not modelled
 - [getpriority](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) follows FreeBSD 11.4's [`sys_getpriority`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_resource.c#L93-L165) for the only guest process, which is taken to run at nice 0: `PRIO_PROCESS` and `PRIO_PGRP` with 0 or its own pid (the guest is taken to lead its own process group, see `kill`) and `PRIO_USER` with 0 or its user id 0 return 0, any other id fails with `ESRCH` and any other `which` with `EINVAL`. As in FreeBSD's libc, where `getpriority` is the bare system call, errno is left unchanged on success. The nice value of a title process on the console is unverified, and the host nice of the process or of the threads `APS5_THREAD_PRIORITY=high` raises is not reported. `setpriority` accepts the same target ids (any other id fails with `ESRCH`, any other `which` with `EINVAL`), clamps the value to FreeBSD's `PRIO_MIN`-`PRIO_MAX` (-20 to 20) and stores it as the guest process's nice value, which `getpriority` returns; the host scheduling class is not changed, and whether a title process may lower the value without privilege is unverified
 - [rtprio_thread, pthread_setconcurrency, pthread_getconcurrency](../../../core/libs/prx/libkernel/Pthread/Posix/Thread.cpp) (libkernel) - `rtprio_thread` follows FreeBSD 11.4's `rtprio_thread(2)`. Every guest thread here runs under `SCHED_FIFO` or `SCHED_RR` (priority 256-767), whose rtprio class is real-time; the console's mapping from that priority to the rtprio `prio` range (0-31) is unmeasured, so `RTP_LOOKUP` and `RTP_SET` throw for such a thread rather than report an impossible priority. A thread that is not real-time reports `RTP_PRIO_NORMAL` (3) with 0, and `RTP_SET` accepts only that value. Another function fails with `EINVAL`, a null `rtprio` with `EFAULT`, a thread other than the calling one throws, and an id that is not a live guest thread with `ESRCH`. `pthread_setconcurrency` stores 0 or more and returns `EINVAL` for a negative level (the error itself, as FreeBSD's libthr does, with errno untouched); `pthread_getconcurrency` returns the level, which is a hint and changes nothing about the host's concurrency. Morrowind (`mshivam019/morrowind-ps5`) imports all three at start-up
+- [sceKernelVirtualQuery](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) returns [VirtualQueryInfo](../../../core/libs/SceTypes.hpp) with a one-byte flag allocation unit so Windows and SysV hosts return the same 72-byte representation, with the name at byte 33 and GPU mask at byte 65. This preserves the existing SysV representation; the console offsets beyond the address, protection and size fields observed in Astro Bot's AGC calls are not hardware-measured. Size and offset assertions plus a raw-byte named-mapping regression guard the host ABI.

Subject: [PATCH 0288/1000] fix(conventions): check comments in GLSL shaders

The comment rule only scanned C++, Python and CMake files, so a
comment added to a .comp, .frag or .vert shader passed the check.
TextureDetile.comp and ColorTransfer.comp carry such comments today.
Shaders are now masked with the same C-style lexer and report
comment on changed lines, with the same #endif allowance and the
same technical-debt exemption as C++.

Argument and encoding checks match `snwprintf_s`
 - [vsnwprintf_s](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - `va_list` counterpart of `snwprintf_s` (C11 K.3.9.1.3): truncates to the buffer and returns the full length, with the same constraints and argument checks
 - [vsnprintf_s and vsscanf_s](../../../core/libs/prx/libc/src/Formatting.cpp) (libc) - `vsnprintf_s` forwards to `vsnprintf` semantics: the C11 K.3.7.1.5 runtime constraints (null buffer, `size == 0`, `%n`, null `%s`) are not checked, so `size == 0` returns the would-be length instead of a negative value, and no constraint handler is invoked. `vsscanf_s` returns the count of items converted before an undersized `%s`/`%c`/`%[` destination (0 when it is the first), not EOF.

It is a fixed C-locale table: whether the console changes it with `setlocale` is not known, and `_Frac_grouping`, `_Frac_sep`, `_No`, `_Yes` are empty strings as in that dump
 - [set_constraint_handler_s](../../../core/libs/prx/libc/src/WideConversion.cpp) (libc, re-exported by libSceAmpr) - the default handler is assumed to abort; each module keeps its own handler state, so a handler set through one library is not seen by the other. `ctime_s` and `asctime_s` follow the Dinkumware 26-byte format with `EINVAL` for a buffer under 26 bytes, a null pointer or an out-of-range weekday/month; `ctime_s` uses the guest time zone of `localtime_s`, and the console's exact checks are not verified

Subject: [PATCH 0295/1000] fix(agc): resolve a GPU-read indirect dispatch at
 the gate when the run writes its arguments

The dispatch look-ahead stopped before every DISPATCH_INDIRECT whose
arguments an earlier dispatch of the run may write, or whose earlier
dispatches have unknown writes. That stop protects a CPU read of the
arguments at the resolve, which only the thread-dimensions, misaligned and
APS5_NO_GPU_INDIRECT paths make. A GPU-read indirect dispatch never reads
its arguments on the CPU, so the stop left it and every dispatch behind it
to be captured when the worker reached them, after the GPU mutex waits
between dispatches. That is the late read the group capture exists to
avoid: by then the title had re-armed the gate and reused its table slots,
and the capture read descriptors the title had not written yet. The
look-ahead now stops only before an indirect dispatch whose arguments it
would read on the CPU; the path choice is shared with dispatchIndirect.

AgcDriverDispatchesAdoptedAhead_nid_postfix counts the dispatches adopted
from the look-ahead so a test can tell a gate-time capture from a late one.
Two tests check through it that both dispatches of a gated group are
captured at the gate: one whose writer stores the indirect arguments
through a registered binding, and one whose writer stores them through a
binding misaligned in its host import.

Subject: [PATCH 0296/1000] fix(agc): sample a depth surface's stencil plane
 through an R8_UNORM view

Vulkan cannot view a stencil aspect as UNORM, so an 8-bit UNORM view of
a stencil plane threw. Copy the stencil aspect through a buffer into an
R8_UNORM image of the surface's extent and sample that. The copy is kept
on the surface and refreshed when the surface was written since, or while
it is the bound depth target.

Subject: [PATCH 0297/1000] test(relinker): convert the SCE module extent
 fixtures for every target

The two fixtures were converted for Windows only. They now run for
Linux, Windows and macOS. The syscall scan of a module with data after
its code fails on all three without the fix, and the loader path
without PT_INTERP fails on Windows and macOS, so the macOS code
analysis stays under test.

Trailing padding stays, as it does there, so an AMD host's name ends in spaces. The name a PS5 reports is unknown. A write returns -1 with `EPERM`. A host without an x86 CPUID brand string, such as an Apple Silicon Mac, throws. PPSA99203 only prints it (`[console] hw.model: %s`)

FreeBSD lets root write it to change the TSC timecounter's frequency; a write here returns -1 with `EPERM`. PPSA99203 reads it at start-up and measures the TSC itself when the value is 100 MHz or less

The console's limit is not known; XPSemu (PPSA97358) reads it in QEMU's `os_setup_limits` and raises the soft limit to the hard one when they differ. `RLIMIT_STACK`, `RLIMIT_RSS`, `RLIMIT_MEMLOCK` and `RLIMIT_NPROC` throw because no console values are established.
 - [setrlimit](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) validates the resource and input in FreeBSD order, maps negative limits to infinity, and lowers a soft limit above the hard limit. A request succeeds only when its normalized values match `getrlimit`; changing limits throws because guest limit state is not stored.

 - In executables and guest modules with a `PT_SCE_DYNLIBDATA` segment, the [code analysis](../../../core/relinker/relinker/src/analysis/CodeInstructionCollector.cpp) of the Windows and macOS outputs follows code only from the end of `PT_INTERP` to the end of the PLT after the last function of the unwind table, the end the pipeline's scans above use; a guest module with PLT relocations and no PLT after its last unwind function fails as the executable does. Code after that PLT is not analyzed: a TLS access in it is not rewritten, an entry point or pointer into it is ignored, and a function symbol or init/fini array entry pointing into it fails the conversion.
 - A relocation against a dynamic symbol entry that is all zero, like the null symbol, takes the value 0 plus its addend, as the gABI defines for `STN_UNDEF` ([pipeline](../../../core/relinker/relinker/src/pipeline/RelinkerPipeline.cpp)). The Linux output imports such an entry as an unnamed weak symbol, which the host loader resolves to 0; the Windows and macOS outputs write the value into the slot ([relocation builder](../../../core/relinker/elfpatcher/src/windows/WindowsRelocationBuilder.cpp)). What the console's loader does with such an entry is not measured. OliSe Player (PPSA01153) has seven of them, and its code calls through those slots only when they are not 0 ([#4437](https://github.com/boykopovar/AnyPS5/issues/4437)).
 - The Linux placement of the `--to-intel` stubs in the [ELF patcher](../../../core/relinker/elfpatcher/src/linux/LinuxElfPatcher.cpp) is covered only by a synthetic test.
-- `--to-rosetta` lowers what Rosetta lacks on top of `--to-intel` ([matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp)). Rosetta runs AVX2, FMA, BMI1/2, F16C and MOVBE but reports none of them through CPUID, so code that checks CPUID takes its baseline path. RDSEED becomes RDRAND and CLWB a NOP. RDPID returns processor 0, because Rosetta's TSC_AUX is the constant 0xAAAAAAAB; the same value reaches RDTSCP's ECX, which is not converted. ADCX/ADOX fault under Rosetta and are not converted: compilers do not emit them, and code that checks CPUID sees no ADX. The conversions are covered by the converter tests; that the converted code runs under Rosetta was checked on an M5 Max only, outside this repository's CI.
+- `--to-rosetta` lowers what Rosetta lacks on top of `--to-intel` ([matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp)). AVX2, FMA, BMI1/2, F16C and MOVBE were observed to execute on an M5 Max without being reported through CPUID; this is not a guarantee for other Rosetta hosts. ANDN and RDRAND fault on an M1 running macOS 15.3.1. ANDN is lowered, but RDRAND and other BMI instructions still depend on the host. RDSEED becomes RDRAND and CLWB a NOP. RDPID returns processor 0, because Rosetta's TSC_AUX is the constant 0xAAAAAAAB; the same value reaches RDTSCP's ECX, which is not converted. ADCX/ADOX fault under Rosetta and are not converted: compilers do not emit them, and code that checks CPUID sees no ADX. The conversions are covered by the converter tests. ANDN lowering is also executed by an x86-64 test build under Rosetta on the M1; the other conversions were originally checked on an M5 Max, outside this repository's CI.
 - `--to-intel` replaces the approximate legacy SSE and VEX.128 register forms of RSQRTPS/RCPPS and VRSQRTPS/VRCPPS with [correctly rounded](../../../core/relinker/codegen/src/x86/ReciprocalLowering.cpp) 1/sqrt(x) and 1/x, not with the AMD approximation: its tables are not public. Intel's approximation of 1/sqrt(1.0) is 0x3F7FF000, and two Newton-Raphson steps on it settle on 0.99999994 instead of 1.0; a renormalised identity quaternion then turns into a NaN axis in PPSA21564, which the console does not show. Refined results now reach the exact value; unrefined ones can still differ from the console in the low bits. Each site costs an out-of-line stub (two jumps, a spill below the red zone, SQRTPS/DIVPS). Legacy SSE forms preserve the destination's upper YMM bits; VEX forms clear them. The 256-bit, scalar and memory forms keep the native instruction, as does a site shorter than 5 bytes with no movable instruction after it for the jump (5 sites in PPSA21564, counted before a following RIP-relative instruction could move into the stub; not recounted).
 - `--trace-imports` ([entry stub](../../../core/relinker/elfpatcher/src/windows/WindowsEntryStubBuilder.cpp)) exists for Windows output only. Only imports bound through a PLT slot, or through a GOT slot whose symbol is a function, are traced; a function reached through any other relocation, or looked up at run time with `sceKernelDlsym`, is not, and neither are weak imports or the imports of modules loaded at run time
+
+- [ANDN lowering](../../../core/relinker/codegen/src/x86/AndnLowering.cpp) uses scalar NOT and AND for 32- and 64-bit register and memory operands under `--to-rosetta`, following the ANDN entry in [Intel SDM volume 2A](https://cdrdv2-public.intel.com/812383/253666-sdm-vol-2a.pdf). SF and ZF follow the result, CF and OF clear, and AF and PF are undefined. The scratch register is saved below the 128-byte red zone. A 64-bit stack-relative displacement that exceeds signed disp32 after reserving the spill frame throws; other BMI instructions are not lowered. The M1 test covers register overlap, RSP operands, memory addressing, RIP relocation, flags and red-zone preservation; precise fault delivery inside a spill sequence has not been verified.

Subject: [PATCH 0301/1000] fix(libSceNgs2): support listener transforms in
 sceNgs2GeomCalcListener

Restore world-to-listener matrix construction instead of rejecting
non-default orientation, translation or flags.

- Build an orthonormal row-major matrix from position, orient_front
  and orient_up; apply the right-handed axis flip for flag 1.
- Store the negated dotted translation in each matrix row.
- Validate unknown flags, invalid or non-finite input, short
  orientation axes, and unrepresentable translation without changing
  the output.
- Preserve finite velocity and positive finite sound speed.
- Update NGS2 geometry tests and the libSceNgs2 technical debt note.

Other locations and types throw. The voice keeps playing a filter tail after its last block until the history is zero, with outputs below 1e-20 flushed to zero (a KytyPS5 choice); the console's tail length is unknown

Speakers are taken in the order L R, L R Ls Rs, L R C Ls Rs or L R C Ls Rs Lb Rb and kept in a fixed circular order, not sorted; without angles the defaults are 90/270, 40/110/250/320, 0/40/110/250/320 and 0/40/110/150/210/250/320 degrees. As in that library, defaults converted to radians keep the wrap-around entry in degrees, so angles past the last speaker pan almost fully to it. Error codes are not known for the PS5, so invalid arguments throw, including a speaker angle equal to the unit angle, on which that library loops forever. Angles so large that adding or subtracting a turn leaves them unchanged throw for the same reason

The defaults (orient front +Z, orient up +Y, sound speed 343, cone 1/360/1/360, rolloff 0/1000000/1/1, doppler factor, full-band, LFE and maximum level 1, two speakers and matrix format 2) are unverified on a PS5 title; KytyPS5 and iStark/PS5PCEM agree on them. PPSA15552 (Dead Cells) calls `sceNgs2GeomResetSourceParam` after creating its racks.

Other orientations (including non-unit vectors), translations and flags throw without changing the output; the matrix convention, handedness flags and console error codes remain unverified. Nonfinite input and nonpositive sound speed also throw. Dead Cells (PPSA15552) reaches this call after the custom sampler rack in #4334, but its arguments have not been captured here. Source attenuation, panning and Doppler in `sceNgs2GeomApply` remain unimplemented

 - [sceNgs2VoiceGetState custom sampler](../../../core/libs/prx/libSceNgs2.native/src/Voice.cpp) (libSceNgs2.native, rack 0x4001) - only the size and one field come from a title. PPSA15552 (Dead Cells) calls it on custom sampler voices with a 48-byte buffer at two sites (eboot `0x1740f90`, `0x1741009`) and reads only the 64-bit value at offset 16: the first site keeps it and the second subtracts the kept value, so it is filled with the voice's decoded sample count. Other sizes return `INVALID_OUT_SIZE` as for the other racks. The state flags fill the common voice state; the remaining fields stay zero. shadPS4's `OrbisNgs2CustomSamplerVoiceState` is about 80 bytes and does not match the size this title passes, so the field names and the console's value are unverified

Subject: [PATCH 0305/1000] fix(agc): accept a min or max reduction sampler
 with anisotropic filtering

A guest S# with FILTER_MODE min or max and an anisotropic XY filter
threw "combines a min or max reduction with anisotropic filtering",
which stops High on Life (PPSA15388) in its home base. It now decodes
to a Vulkan sampler with both anisotropy and the reduction mode, as a
weighted-average anisotropic S# already does. RADV programs the same
S# for such a Vulkan sampler.

Tamalero's gfx1030 measurement on #5156 covers a sample without
derivatives through a 2x anisotropic S# over a single-level texture:
min or max with anisotropic bilinear returns the bilinear minimum or
maximum, and min with anisotropic point the point result. The
execution test checks the bilinear case on the host GPU; the debt
entry records what is not measured.

Measured on RDNA2 (gfx1035), not on the console: through `image_load` and `image_sample_lz`, X, Y, Z (and W of `1_5_5_5` and `4_4_4_4`) come from the low, middle and high fields, and W of `5_6_5` returns X (the low 5 bits), not 1.
 - [Min/max S# reduction](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) - `FILTER_MODE` 1 and 2 use Vulkan's min and max reduction (the same `SQ_IMG_FILTER_MODE` values RADV programs). Measured on RDNA2 (gfx1035), not on the console: only texels of non-zero weight are reduced, and the weight is taken after rounding to the 8-bit subtexel grid (a sample within 1/512 texel of a centre reduces that texel alone); a driver with other `subTexelPrecisionBits` reduces a different set there.

Only a sample without derivatives is measured: on gfx1030, a 2x anisotropic S# over a single-level texture returns the bilinear minimum or maximum, and min with anisotropic point the point result ([#5156](https://github.com/boykopovar/AnyPS5/pull/5156#issuecomment-6155265616)). A real anisotropic footprint and max with anisotropic point are not measured, and Vulkan leaves nearest filtering with anisotropy to the host driver.

Measured on RDNA2 (gfx1035), not on the console: `8`, `8_8` and `8_8_8_8` sRGB textures sample bit for bit the same with and without the bit (point and bilinear; BC formats not measured). Other textures throw; on the same hardware their UNORM `8`, `8_8` and `8_8_8_8` forms sample bit for bit as the sRGB format (decoded before filtering).
 - [Tessellation factor ring](../../../core/libs/prx/libSceAgcDriver/State/src/Configuration.cpp) (libSceAgcDriver) - `sceAgcDriverSetTFRing` records the ring and `sceAgcDriverGetTFRing` reports it. Before a title sets one, it reports the console's default, 0xFF0000000 and 128 KiB, as measured in [PS5_Vulkan's hardware findings](https://github.com/mihawk-99/PS5_Vulkan/blob/fde9e3798c2ec1d8fccc90d5067cd6060490607f/docs/HARDWARE_FINDINGS.md). Nothing is written to the recorded ring: tessellated draws run as Vulkan tessellation stages, which keep their factors on the host, so a title that reads tessellation factors from the ring finds none. A null base or a zero size throws; [ps5-opengl's AGC runtime](https://github.com/blackbearreloaded/ps5-opengl/blob/67c873f985eaefe0a72f713529e5632eaa01139c/src/platform/ps5_agc_native_runtime.c) calls `sceAgcDriverSetTFRing(0, 0)` in its cleanup, and what that does on the console is unknown.

The copy still spans the whole fetch, but the bytes from `num_records * stride` onward read as zeros, so the out-of-range vertex is `(0, 0, 0, 0)`. Measured with `buffer_load_format_xyzw` (`idxen`) through the [hardware oracle](../HW_ORACLE.md) on RDNA2 gfx1036 for PPSA01325's word 3 `0x0004dfac` (`OOB_SELECT` 0) in #2241: indices 3, 4 and 5 over 3 records each return `00000000 00000000 00000000 00000000`, W included, unlike Vulkan `robustBufferAccess`, which returns `(0, 0, 0, 1)`. The zeros come from the record check, not from memory: stored values placed past the records are ignored, and a `num_records` 6 control returns them. `RESOURCE_LEVEL` 1, `OOB_SELECT` 1 and FORMAT 74 `32_32_32_FLOAT` give the same zeros, in wave32 and wave64; gfx1013 (the console) is not measured. `OOB_SELECT` 2 returns the stored values past the records and `OOB_SELECT` 3 compares `num_records` against the byte offset, both measured on the same setup in #2241; the two keep throwing past `num_records` here, since each needs its own rule. Zero-stride descriptors (`stride` 0) keep their separate byte-count check and are not covered here. Each out-of-range fetch is copied alone and outside the draw-snapshot cache, which is neither read nor written for it: a reused snapshot would carry another draw's bytes into the zero region, and a stored zero-padded copy would hand zeros to a later in-range draw at the same address. The valid prefix is still flushed for GPU writes before it is read.

Subject: [PATCH 0308/1000] fix(agc): settle dma-buf imports on Linux on the
 settle queue

The kernel maps a dma-buf import's pages for the GPU at the first submission that uses it. On RADV
that took about 2 s for a 3 GiB import, in the second frame of Hades (PPSA03355), and its staging
pool ran out while the frame was held.

Linux now makes the settle queue from #6060 when the device imports dma-buf memory, and settles
every dma-buf import of 1 MiB or more right after it is made with settleImport's 4-byte copy. The
settle queue needs neither the GPU mutex nor the main queue's work to finish. A dma-buf import's
buffer is shared with the settle queue's family instead of aliased, since a sparse import is bound
to many memory objects. Where the sparse queue already takes that family, the settle queue is a
second queue of it.

 - A draw whose `PA_SC_AA_CONFIG` selects 2, 4 or 8 samples renders into host-only multisampled images. [`MultisampleTarget.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) keeps one image per device, surface address, format, extent and sample count (`MultisampleTargetView`); the pipeline, render pass and library keys carry `State::samples`, and a multisampled depth target is a multisampled depth surface. The guest sample planes and FMASK are never read or written, so the registry also guards the target's guest range: a CPU read (`GuestMemory::SetReadGuard`), a DMA copy, and a sampled or storage image read of it throw. A `CB_COLOR_CONTROL` resolve mode over a multisampled CB0 runs as a render pass whose resolve attachment is CB1's resident image (`ResolveMultisampleTarget`). A zero fill of the target's CMASK (`NoteColorMetadataFill`, from fill kernels and CP DMA fills) clears the image at its next use.
 - A texture over a depth surface samples the depth image itself when it views one 2D slice of the plane's own format (`DepthSurfaceTexture` in [`DepthSurface.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp)). A view of several slices (a 2D array or a cube) or an integer view of a D16 plane is served by a `DepthPlaneCopy`, an image the slices are copied into at every use: from the depth surface bound at each slice's address, else from guest memory. Such a texture is never kept in the resource templates (`RefreshedPerUse`).
 - Guest memory reaches the GPU through host imports (`VK_EXT_external_memory_host`) where the driver accepts them, and through copies otherwise ([`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp)). A registered range larger than the import window (64 MiB) is imported per window for buffer and fill accesses and whole for an address-based build. Live imports stay under a budget, with the least recently used import retired first (see TechnicalDebt, Host import windows and budget).
-- On Windows, a host import of private `MEM_WRITE_WATCH` memory (singly mapped direct memory) stays on `GetWriteWatch` when `ProbeImportWriteProtection` shows the driver reports nothing written after the second GPU read and a GPU write, and a CPU store is collected (`decideImportWatch`). The driver marks every page of such an import written, asynchronously, until its first GPU use completes, so `settleImport` in [`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) copies 4 bytes out of the new import on a second queue of the graphics family, or on a queue of another copy-capable family when the graphics family has only one (`Context::settleQueue`, own pool and mutex) inside `ImportWatched`'s window and waits for it, only for imports of 1 MiB or more (a smaller import is compared, so a title that maps, imports and unmaps a small buffer around every submission does not block its mapping thread); the main queue can't be used there because `importAllocation` holds the imports lock and `GpuMutex` comes before it in the lock order. Imports through a section alias keep tracking on the guest views, and every other Windows host import is compared. A device without such a queue keeps the comparisons.

On Linux the settle queue is made when the device imports dma-buf memory, and every dma-buf import of 1 MiB or more is settled right after it is made, for another reason: the kernel maps an import's pages for the GPU at the first submission that uses it, which took about 2 s for a 3 GiB import on RADV and held up the title's frame. The import's buffer is shared with the settle queue's family instead of aliased, since a sparse import is bound to many memory objects.

 - [Pending storage-image results over memory outside the write watch](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) leave to the CPU the 64 KiB blocks whose bytes differ from the ones saved at the upload, the fill, the image copy, the previous store or the moment their range left the watch (`Unwatch`, or a host import that does not stay watched), and the blocks the watch saw the CPU write before that moment. A store made on the GPU saves its bytes through a host-visible copy that becomes the saved bytes when its batch completes; a store or a refresh that needs them earlier waits for that batch. A unit without a write generation saves the guest bytes when results land in it outside the watch. One whose range leaves the watch while its results are pending, and ranges that leave the watch through a failed collect, have no saved bytes; storing such results throws.
 - Windows host-pointer imports of the guest mapping itself are compared instead of write-watched, except writable imports of private `MEM_WRITE_WATCH` memory of 1 MiB or more when the import probe keeps the write watch and a settle queue exists (see Pages under an import window): a driver can mark imported pages dirty after the synchronous import window. Shared memory imported through a separate writable alias retains protection-based tracking on the guest views; driver access to the import alias does not disarm those views. [GuestMemory](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) excludes every overlapping 64 KiB tracker block while its backing is retained. A full block replaced by fresh private backing regains tracking and gets a new generation; protection changes, partial replacements and shared remappings do not restore it. Excluded blocks keep their write-watch marks as a hint only (`UntrackedHint`): a storage image or a sampled texture snapshot over them compares its bytes again after a mark in its range, a driver store, a mapping change or a recorded GPU write instead of at every collect epoch or lookup, and a mark the driver makes without a CPU store costs one comparison. This preserves CPU edits through byte comparisons but limits snapshot reuse on excluded blocks to draws of one collect epoch and disables unit shadows for them; restoring tracking on import retirement without replacing the backing remains unimplemented.
 - [Pages under an import window](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) (libSceAgcDriver) whose write protection was resolved while a host import that leaves its range watched was made are compared with the bytes they held before the import and count as stored over only when those differ. A CPU store of the bytes already there within the window cannot be told apart from an import that resolves the write protection without storing, as the NVIDIA driver (610.57.04) does for every imported page, so such a store does not win over pending results. Where host-pointer and dma-buf imports differ in whether they stay watched, a failed host-pointer import and the dma-buf import after it are two windows, and the pages the failed one resolved count as stored over. On Windows, the NVIDIA driver (617.42) marks every page of a host import of private `MEM_WRITE_WATCH` memory written, asynchronously, until the import's first GPU use completes. Such an import stays watched only after a 4-byte read of it on the settle queue has completed inside the window. Each one waits for that read, which keeps its window open for one round trip on the settle queue, so a same-value CPU store from another thread in that time counts as unchanged too. An import made where no settle queue exists, and an import of under 1 MiB, is compared instead: the settle blocks the importing thread, and a title that imports a 64 KiB buffer around every submission lost about 19 % of its frame rate to that wait (Dripl1x, #6060). Settling without blocking the importing thread (submit the read, keep the import compared until its fence signals, then switch it to the write watch) is not implemented.
+- [Settled dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a dma-buf import of 1 MiB or more is read by a 4-byte copy on the settle queue right after it is made (`settleImport`), so the kernel maps its pages for the GPU there and not in the first submission that uses it (about 2 s for a 3 GiB import on RADV). The import's buffer is shared with the settle queue's family. An import made from a submission settles under the GPU mutex, so its frame still pays for it; a smaller import, and every import on a device with no settle queue (one without a copy-capable queue besides the main one), pays in its first submission
 - [Sparse dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a shared-backed range larger than one 64 MiB udmabuf buffer is imported as one sparse buffer bound to the 64 MiB buffers, on a queue of its own when the device has a second family that binds sparse memory. The path is decided before anything is imported, and a failure after that throws. A range takes the single udmabuf import instead, which udmabuf's `size_limit_mb` refuses above 64 MiB by default so the range is copied, when its offset in the backing file is not a multiple of the buffer's sparse block size (64 KiB on RADV), when the sparse buffer does not accept every memory type a chunk import can have, when the backing file ends inside its last chunk, or when it is imported at map time on a device with no second family (the bind then needs the GPU mutex); the NVIDIA proprietary driver imports no dma-buf memory
 - [Unnormalized S# coordinates](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) - `FORCE_UNNORMALIZED` uses a Vulkan `unnormalizedCoordinates` sampler, so the S# LOD range, LOD bias and mip filter are not applied, which is exact only on a one-level view.
 - An [unnormalized S#](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) maps clamp mode 0 (repeat) on X and Y to clamp-to-edge as required by Vulkan unnormalized coordinates, and assigns the magnification filter when minification and magnification filters differ (since unnormalized coordinates sample at LOD 0). Anisotropy, TRUNC_COORD, MC_COORD_TRUNC and other clamp modes still throw. Secondary LOD bias (LOD_BIAS_SEC, bits [19:14]) is accepted and ignored, matching RDNA2 hardware measurements across explicit and implicit samples. High on Life (PPSA15388, #4736) uses secondary LOD bias and unnormalized coordinates with clamp mode 0 and differing min/mag filters during home base and city rendering.

Subject: [PATCH 0309/1000] ci(windows): find the CA bundle of Git for Windows
 under ucrt64 too

Git for Windows 2.56 (runner image 20261002) moved from mingw64 to ucrt64,
so the fixed SSL_CERT_FILE path no longer exists and the WinLibs CMake
fails the FFmpeg download with status 60 on every Windows build. Take the
bundle from whichever of ucrt64 and mingw64 exists.

 ### Unknown function info
 
 - [fdopen](../../../core/libs/prx/libc/src/FileAndHeap.cpp) (libc) validates descriptor access modes as FreeBSD 11.4 [fdopen.c](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdio/fdopen.c) does: a requested mode incompatible with a descriptor not opened for both reading and writing returns null with `EINVAL`, leaving the descriptor open. Windows reads the handle's granted access through the same host helper as `fcntl(F_GETFL)`; a closed descriptor returns null with `EBADF`. Console behavior is unverified.
+- [scriptingGetMem, scriptingFreeMem](../../../core/libs/prx/libc/src/ApplicationHeap.cpp) (libc) - runtime allocator hooks for Unity titles. The allocation signature `(alignment, size)`, minimum alignment 16 and null result for a non-power-of-two alignment follow [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/df5b9b92be7dfd463b47756b707d6d356a9f0550/src/libs/libKernel.cpp); the free hook's one-pointer signature follows [Raeen's recorded contract](https://github.com/Whoisraeen/Raeen/blob/2db56923204b89719916b95e29c2f3c4e1d9f90b/docs/unity-dlsym-blocker.md). Both use the registered application allocator. No console measurement; null allocation returns null and other allocator errors throw.
+
 - [_Mtx_trylock](../../../core/libs/prx/libc/src/Threads.cpp) (libc, NID `k6pGNMwJB08`) - returns busy for a non-recursive mutex already owned by the caller, assumed to match `_Mtx_lock`'s ownership handling; exact console behavior is unverified.
 - [nearbyintf](../../../core/libs/prx/libc/src/Math.cpp) (libc, NID `c+4r-T-tEIc`) uses the host rounding mode, not the console's; console rounding mode state remains unverified.
 - [_Thrd_sleep](../../../core/libs/prx/libc/src/Threads.cpp) (libc, NID `jfRI3snge3o`) follows the Dinkumware threads library shipped with [Visual C++ 2013](https://github.com/adityaramesh/concurrency_runtime/tree/master/VS2013_SP2/crt/src/thr) (`xtime.c`) and C11 Annex K, without console verification. It reads a 16-byte xtime (64-bit seconds and nanoseconds) on the guest `CLOCK_REALTIME`, normalizes the nanoseconds and sleeps through `nanosleep`, retrying on `EINTR`, so it is a cancellation point; a null xtime or one whose normalization overflows throws. The console's `_Thrd_sleep` (disassembled from a title's `libc.prx`) also takes an optional `xtime*` of remaining time and returns `int`; here the sleep is never cut short, so it returns 0 and leaves the remaining time untouched.

Subject: [PATCH 0312/1000] perf(agc): load the pipeline cache file only on the
 windowed device and save without re-reading an unchanged file

The headless device is replaced by the windowed one at window attach and then only
lingers for in-flight workers, but it parsed its own full copy of the cache file.
It now starts empty (it still merges what it compiles into the file). Load reuses
the file buffer as the initial data instead of copying it, and save() writes the
live data directly when the file still carries the header this object loaded or
wrote, skipping the read-back and the merge cache.

 - Fedora: if CMake reports `Could NOT find Threads`, install `glibc-static` and `libstdc++-static` with `sudo dnf install glibc-static libstdc++-static`, then rerun configuration. The project enables static executable linking, and FFmpeg's thread check needs these libraries.
 - Windows: only MinGW-w64 GCC 15.2.0 (WinLibs `x86_64-ucrt-posix-seh`, release [`15.2.0posix-14.0.0-ucrt-r7`](https://github.com/brechtsanders/winlibs_mingw/releases/tag/15.2.0posix-14.0.0-ucrt-r7), archive `winlibs-x86_64-posix-seh-gcc-15.2.0-mingw-w64ucrt-14.0.0-r7.zip`) is currently supported. Add its `mingw64/bin` directory to `PATH` before configuring.
 - Windows antivirus software can quarantine the executables that the relinker tests create in the temp directory, which fails `optional_plt`, `empty_tls`, `windows_address_space` and `windows_icon`. Set `TEMP` and `TMP` to a directory the scanner excludes before running `ctest`.
+- Bitdefender Advanced Threat Defense hooks Windows calls that `sceKernelRaiseException` makes while its target thread is suspended. When the target is suspended inside ntdll's exception dispatch while it holds an ntdll lock, the hook waits for that lock and `guest_raise_exception` hangs until its timeout. A scanning exception for the build directory does not prevent it; add `guest_raise_exception_tests.exe` to the Advanced Threat Defense exceptions.
 - FFmpeg binaries are downloaded during configuration unless `FFMPEG_PREBUILT_DIR` is set. With the WinLibs CMake, the download fails with status 60 (`SSL peer certificate or SSH remote key was not OK`) unless `SSL_CERT_FILE` names a CA bundle, for example `C:\Program Files\Git\ucrt64\etc\ssl\certs\ca-bundle.crt` from Git for Windows 2.56 and later (`mingw64` instead of `ucrt64` before 2.56), as in CI.

The PS5's gfx1013 is not measured. A plain `image_sample` (implicit LOD) through such a pair takes its LOD from the derivatives of the first coordinate alone, measured on RDNA2 (gfx1036) with the [hardware oracle](../HW_ORACLE.md) on the quads of a compute kernel (wave32 and wave64, IEEE off, DX10 clamp on, denormals preserved, round to nearest even): on a 16-texel, 5-mip 32_UINT T# with point filters it picks the same mip and texel as DIM 1D for first-coordinate steps of 0, 1, 2, 4 and 8 texels per lane along x or along y, whatever the second coordinate does (normalised steps up to 16 per lane), while the same rows on a 16x16 2D T# move the mip with the second coordinate. Outside the pixel stage a plain `image_sample` is emitted with LOD 0 for every image type, so this pair reads mip 0 there, where the kernel measurement shows the quad's derivatives being used. `image_sample_c_lz` and plain `image_sample_c` through such a pair compare against the texel the DIM 1D comparison with the same reference and first coordinate reads, measured on RDNA1 (gfx1010, RX 5700 XT) with the [hardware oracle](../HW_ORACLE.md) template run through the Windows driver's comgr and HIP runtime (wave32 and wave64, IEEE off, DX10 clamp on, denormals preserved, round to nearest even): 8-texel 32_FLOAT and 16_UNORM T#s, also with HEIGHT 3, point and bilinear filters, wrap, clamp and opaque-white border addressing, less and gequal functions, second coordinates 0, 0.5, 1, 1.5, -0.25 and 3; on a 64-texel, 7-mip 32_FLOAT T# `image_sample_c` picks its LOD from the first coordinate's steps alone (1, 4 and 16 texels per lane give mips 0, 2 and 4; second-coordinate steps up to 64 texels leave it unchanged). Only comparisons the runtime does natively (32_FLOAT, 16_UNORM) reach the 1D view; comparisons the runtime emulates for other color formats still throw through such a pair. Other 2D accesses through a 1D T# (storage, depth, packed, BY loads, mips other than explicit LOD, explicit LOD with comparison, bias, offsets, derivatives) still throw.

A plain `image_sample` (implicit LOD) through such a pair takes its LOD from the derivatives of the first coordinate alone, measured on RDNA2 (gfx1036) with the [hardware oracle](../HW_ORACLE.md) on the quads of a compute kernel (wave32 and wave64, IEEE off, DX10 clamp on, denormals preserved, round to nearest even): on a 16-texel, 5-mip 32_UINT T# with point filters it picks the same mip and texel as DIM 1D for first-coordinate steps of 0, 1, 2, 4 and 8 texels per lane along x or along y, whatever the second coordinate does (normalised steps up to 16 per lane), while the same rows on a 16x16 2D T# move the mip with the second coordinate. Outside the pixel stage a plain `image_sample` is emitted with LOD 0 for every image type, so this pair reads mip 0 there, where the kernel measurement shows the quad's derivatives being used. `image_sample_c_lz` and plain `image_sample_c` through such a pair compare against the texel the DIM 1D comparison with the same reference and first coordinate reads, measured on RDNA1 (gfx1010, RX 5700 XT) with the [hardware oracle](../HW_ORACLE.md) template run through the Windows driver's comgr and HIP runtime (wave32 and wave64, IEEE off, DX10 clamp on, denormals preserved, round to nearest even): 8-texel 32_FLOAT and 16_UNORM T#s, also with HEIGHT 3, point and bilinear filters, wrap, clamp and opaque-white border addressing, less and gequal functions, second coordinates 0, 0.5, 1, 1.5, -0.25 and 3; on a 64-texel, 7-mip 32_FLOAT T# `image_sample_c` picks its LOD from the first coordinate's steps alone (1, 4 and 16 texels per lane give mips 0, 2 and 4; second-coordinate steps up to 64 texels leave it unchanged). Only comparisons the runtime does natively (32_FLOAT, 16_UNORM) reach the 1D view; comparisons the runtime emulates for other color formats still throw through such a pair. 2D-array `image_sample_l` and `image_sample_lz` through a 1D T# read as DIM 1D too, ignoring v and the slice: measured on gfx1036 with the hardware oracle (template assembled by the AMD Windows driver's `amd_comgr_2.dll` and launched through its `amdhip64_6.dll`) against the same sample with DIM 1D on a 16-texel 8_8_8_8 UNORM T# with 1 or 5 levels, HEIGHT or DEPTH 3, for u inside, on and past the edges, v of 0, 0.5, 1, -0.25 and 3, slices 0, 1, 2.7, -1 and 5, LOD -1 to 6, and the five filter and address cases above: all 48000 rows matched. A 2D-array `image_load` through a 1D T# is not the same: on gfx1036 it returns the DIM 1D texel only at slice 0, and zeros at slices 1, 2, 5 and -1 even with DEPTH 3, so it, the plain `image_sample` and the other 2D-array accesses still throw. Other 2D accesses through a 1D T# (storage, depth, packed, BY loads, mips other than explicit LOD, explicit LOD with comparison, bias, offsets, derivatives) still throw.
 - [3D image accesses bound to a 1D T#](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) follow a [hardware oracle](../HW_ORACLE.md) measurement on RDNA1 (RX 5700 XT, gfx1010; wave32 and wave64, IEEE off, DX10 clamp on, denormals preserved, round to nearest even), not the PS5's gfx1013, on 8x1 R8G8B8A8_UNORM linear 1D T#s with HEIGHT and DEPTH 0 or 3 and point filters. `image_sample_lz` reads the texel u selects for v and r in {0, 0.5, 1, 1.5, -0.25, 3}, with wrap, clamp and border addressing, and v and r never produce the border; u wraps, clamps and borders as with DIM 1D. Mip-less `image_load` reads the x texel for any y in {0, 1, 2, 3, -1} when z is 0, returns zero for z in {1, 2, 3, -1}, whatever DEPTH says, and returns zero for x past the width. A plain `image_sample` (implicit LOD) on the quads of a compute kernel takes its texel and LOD from u alone: on a 64-texel, 7-mip 1D T# steps of 1, 4 and 16 texels per lane pick mips 0, 2 and 4, as DIM 1D `image_sample_l` does, and steps in v or r alone stay at mip 0. Outside the pixel stage a plain `image_sample` is emitted with LOD 0, as for 2D accesses through a 1D T#. Every other 3D access of such an image (`image_load` with mips, storage, explicit LOD, bias, derivatives, offsets, comparison, gathers, queries) keeps throwing. SONIC SUPERSTARS (PPSA06888) samples a 1x1 1D T# this way with plain `image_sample` and `image_load`.
 - [Emulated comparison of a 2D-array access through a 2D T#](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) samples the 2D image and ignores the slice, as the native modes of a 2D-array access through a 2D T# already do. This follows the T# type deciding the addressing; it is not measured on hardware for comparison samples
 - [Flat aperture bases](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (core/shader/recompiler) - the layout follows the gfx9+ one in the AMD KFD driver's `kfd_flat_memory.c` (`MAKE_LDS_APP_BASE_V9`, `MAKE_LDS_APP_LIMIT`): each aperture is a 4 GB window whose base is the high dword, so a flat address is routed by its whole high dword, as measured on RDNA2 (gfx1035: `src_shared_base` 0x00010000_00000000, `src_shared_limit` 0x00010000_ffffffff). The PS5's base values, high dwords 0x80000000 (shared, `SharedApertureHigh`) and 0x70000000 (private, `PrivateApertureHigh`), are inferred from GTA V's traversal addresses, not measured on a console or read from SH_MEM_BASES. The scalar aperture sources read the same two values

Subject: [PATCH 0318/1000] fix(shader): count a selected record's dwords past
 its buffer as read

Since 682b07eb0, an image whose dword 3 wasn't captured is poisoned
(OutsideSnapshot). A record selected past the end of its heap reads
nothing there, so it was poisoned instead of selecting a null image, and
agc_shader_bindless and agc_driver_image_table failed after the merge of
main. A scalar buffer load returns zeros past the end of the buffer, so
those dwords now count as read zeros, and the dwords the selection reads
count as captured. Every other path keeps main's rule.

 ### Functional
 
+- [sceImeKeyboardOpen, sceImeKeyboardClose](../../../core/libs/prx/libSceIme/Export.cpp) (libSceIme) - opening a keyboard that is already open for the same user returns `0x80bc0001` (busy) and closing one that is not open returns `0x80bc0002`, as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/main/src/libs/ime.cpp) does; it tracks one keyboard for all users, while the open state is kept per user id here, and the PS5 result is unverified
 - [sceImeKeyboardGetInfo](../../../core/libs/prx/libSceIme/Export.cpp) (libSceIme) returns `0x80bc0023` (no resource id) for every id while a keyboard is open, since the IME keyboard never reports a connected device. [sceImeKeyboardSetMode](../../../core/libs/prx/libSceIme/Export.cpp) validates the mode bits but the mode has no effect, as no IME keyboard events are delivered.
 - [sceImeKeyboardGetResourceId](../../../core/libs/prx/libSceIme/Export.cpp) (libSceIme) reports that no USB keyboard is connected (`0x80bc0004`, as [shadPS4](https://github.com/shadps4-emu/shadPS4) does) because IME keyboard events are not delivered to the handler, although [libSceKeyboard](../../../core/libs/prx/libSceKeyboard/src/keyboard_impl.cpp) exposes the host keyboard

 - [Shared memory](../../../core/libs/prx/libkernel/File/src/SharedMemory.cpp) (libkernel) on Linux implements anonymous and named objects, bounded descriptor writes and seeks, and `shm_unlink` with effective read/write permission checks from FreeBSD 11. Named paths up to 1023 bytes use `/anyps5-shm-` plus SHA-1; collisions are not detected, and the namespace is shared across processes in the host mount namespace. Named creation applies the guest umask without changing the host mask. Linux procfs and `/dev/shm` are required. Operations use an advisory directory lock; external host operations bypass it, unrelated objects serialize, and descriptor operations require two spare host descriptors and compare device/inode with the initial descriptor identity on both the pinned-object and ordinary-file fallback paths. [Guest mappings](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) support shared and private mappings of these descriptors through the allocation tracker and pin a duplicate descriptor during validation and mapping; mapping requires one spare host descriptor; file-backed mappings use the write-watch scan fallback because aliases and descriptor writes bypass per-mapping tracking. Named objects and file-backed mappings on Windows remain unsupported. Invalid non-null name pointers, console behaviour and title compatibility remain unverified.
 - [sceKernelAddReadEvent and sceKernelAddWriteEvent](../../../core/libs/prx/libkernel/Equeue/Equeue.cpp) (libkernel): a write event reports the socket's send buffer size (`SO_SNDBUF`) in `data`, not the free space left in it, as Windows has no query for that space. Only guest sockets are supported; other descriptors and a low watermark above 1 throw
 - [close](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) and [setsockopt](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) reach a [libSceNet](../../../core/libs/prx/libSceNet/Export.cpp) socket through hooks libSceNet registers, as `select` polls them; the other libkernel socket calls do not. libSceNet numbers its sockets from 32 in its own table, so a CRT file descriptor and a socket can share a number; `close` then closes the socket. On the console both are one kernel descriptor space
-- [sceKernelPread, sceKernelPwrite, sceKernelPreadv, sceKernelPwritev](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on Windows transfer at the given offset with an overlapped `ReadFile`/`WriteFile` and restore the descriptor's file pointer afterwards, so a concurrent `read`/`write` on the same descriptor can see the moved pointer in between, unlike on the console. Handles that are not disk files return `ESPIPE`. `readv` on a pipe or console handle stops after the first iovec read, a short read the console is assumed to allow; each iovec is transferred separately, so a failure after the first transfer returns the bytes already done
+- [sceKernelPread, sceKernelPwrite, sceKernelPreadv, sceKernelPwritev](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on Windows transfer at the given offset with an overlapped `ReadFile`/`WriteFile` and restore the descriptor's file pointer afterwards. Guest scalar transfers, positioned transfers, vectored transfers and seeks share a position lock across duplicated descriptors; a vector holds it for the whole operation. Independently opened descriptors and other processes do not share that lock, so vector transfers over their overlapping file ranges are not coordinated. Handles that are not disk files return `ESPIPE`. A pipe or console `readv` can return a short read when no more input is available; each iovec is transferred separately, so a failure after the first transfer returns the bytes already done
 - [sceKernelAioSubmitReadCommands, sceKernelAioSubmitWriteCommands and their Multiple variants](../../../core/libs/prx/libkernel/Aio/src/Aio.cpp) (libkernel) on Windows transfer through the same positioned path as `sceKernelPread`/`sceKernelPwrite` and restore the descriptor's file pointer afterwards; positioned transfers, plain transfers and seeks of one descriptor are serialized per descriptor (shared across duplicated descriptors), so a concurrent transfer observes a stable file pointer
 - [sceKernelAioSetParam](../../../core/libs/prx/libkernel/Aio/src/Aio.cpp) (libkernel) writes the five values into the 20-byte scheduling struct the first argument points to, following the declarations in [Orbital](https://github.com/AlexAltea/orbital/blob/cc408367da6a6ebbf5ac1ac559fefeadc73b2831/tools/ida/db_types.json), [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Kernel/KernelAio.cs) and [ampr_emu](https://github.com/drakmor/ampr_emu/blob/cfa85df379f6eeeb165d7badf9b648e266fe77b7/ps5/include/sce/_fs.h). Whether the console checks the values is unknown, so a null struct, a scheduling window or delayed count limit outside 0..128, a split flag other than 0 or 1 and a split size or chunk size above 0x1000000 (SharpProspero's maximums) throw. The scheduling settings are not used: `sceKernelAioInitializeImpl` ignores the struct and requests run synchronously on submit
 - [sceKernelGetFsSandboxRandomWord](../../../core/libs/prx/libkernel/System/src/Sandbox.cpp) (libkernel) returns a fixed directory name, `gkbHtXc3Wq`. On the console the name is the process's randomized path (syscall 602, `randomized_path`), and the sandbox exposes system files under it, such as `common/lib` and `common/cert`. Nothing is mounted under the name here, so `/gkbHtXc3Wq/common/...` resolves under the guest root like any other path and does not exist

Subject: [PATCH 0325/1000] test(agc): keep waiting for the neighbour copy
 case's result

The NeighbourCopied case returned Missed as soon as the surface image was
live with nothing pending, although its result had not reached guest
memory yet. It now waits until the result is pending or stored, as
HoldPending does, and only a stored result is a miss.

Fixes #6383

Subject: [PATCH 0334/1000] fix(agc): treat a TYPE 1 T# in a read-only static
 image slot as null

A static, read-only image slot whose T# has TYPE 1 is now bound as a null
image, like TYPE 0 since #5473 and #4779. On gfx1010, image_sample_lz,
image_sample_b, image_load and image_get_resinfo through a format-22
TYPE 1 T# return zeros without a fault, and gfx1035 reads it as zeros
too. Written, atomic and table slots still throw, and the reserved
types 2-7 stay refused.

 ### Functional
 
 - [Initial stencil state](../../../core/libs/prx/libSceAgcDriver/Execution/include/QueueState.hpp) uses zero for `DB_STENCIL_CONTROL`, `DB_STENCILREFMASK` and `DB_STENCILREFMASK_BF` (context `0x10b`-`0x10d`), including after `CLEAR_STATE`. The public V0, V4, V5 and V7-V11 [register-default tables](../../../core/libs/prx/libSceAgc/Command/include/RegisterDefaultsData.hpp) supply these values. Linux's [GFX10 clear-state table](https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/amd/amdgpu/clearstate_gfx10.h) agrees on the control register but uses `0x01000000` for the reference masks; the console reset values have not been measured. Planet Coaster (PPSA01736 v01.017) enables stencil tests without writing the control register.
-- [Type-0 texture descriptors](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) (`TYPE` = 0 in dword 3) with a nonzero base are bound as null images, like a zero base. The behaviour comes from a gfx1036 (RDNA2) measurement in issue #4139 (image sample, load and resinfo return zero, no fault); it was not measured on the console's gfx1013.

TYPE 0 comes from a gfx1036 (RDNA2) measurement in issue #4139 (image sample, load and resinfo return zero, no fault). TYPE 1 comes from a gfx1010 (RDNA1) measurement in #4139 and #5828 (`image_sample_lz`, `image_sample_b`, `image_load` and `image_get_resinfo` return zero, no fault) with format 22 only; TYPE 1 is not measured on RDNA2, with other formats or with depth-compare reads (`image_sample_c*`). Neither type was measured on the console's gfx1013.
 - [Multisampled color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) lose their guest-read guards and cannot be reused after a successful allocation removal or unmap covers their full guarded range. Retired Vulkan images remain allocated until device teardown to preserve outstanding references. Partial unmaps keep the guard; partial allocation reuse and guest access to live multisampled data remain unsupported.
 - [Stencil reference export replay](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) on devices without `VK_EXT_shader_stencil_export` supports at most sixteen values proved from constant, select and phi exports, with an export proved on every kept path. It records instances, then their triangles, then the reference classes of each triangle. One pipeline filters fragments at shader termination against a dynamic push value before late stencil and depth tests. The [Vulkan stencil-reference replacement rule](https://docs.vulkan.org/refpages/latest/refpages/source/FragStencilRefEXT.html) discards bits above the attachment's stencil width; supported stencil attachments have eight bits. Numeric subgroup observations throw except bounded own-lane mask plumbing and group control with kept-lane and derivative-helper coverage proved. WQM inputs must exclude helper contributions, since [non-quad subgroup operations may treat helpers as inactive](https://docs.vulkan.org/glslext/latest/glslext/khr/GL_KHR_shader_subgroup.html). Readonly guarded SRT reads may report internal host faults; these draws wait and check faults before publishing results, and loops throw. Indirect draws, restart, strips, fans, tessellation, mesh, multisampling, early tests, ordered pixel execution, guest shader memory writes, other fault-producing memory access, clocks, primitive ID inputs, attachment feedback and pipeline face/channel splits throw. An exhausted stage push range throws. Equivalence to console ordering has not been measured on console hardware.

 - [Graphics pipeline libraries](../../../core/libs/prx/libSceAgcDriver/Graphics/src/PipelineLibrary.cpp) (libSceAgcDriver): a pipeline is fast-linked at the draw and relinked with `VK_PIPELINE_CREATE_LINK_TIME_OPTIMIZATION_BIT_EXT` on a background thread, and binds the optimized one from the next draw on. Draws recorded before that use the fast link, whose vertex stage keeps the outputs the fragment stage does not read: on RADV (Radeon 660M, Mesa 26.2.4) 346 of 483 Astro's Playroom vertex shaders paired with a fragment stage that reads none of them used more VGPRs (median 8 more, up to 2.5 times), and on an RTX 4090 13 of 15 PPSA36082 vertex shaders up to 68 instead of 38 (#2242). The optimized link compiles to the same code as a whole pipeline
 - [Prebuilt pipeline libraries](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) (libSceAgcDriver): each registered vertex or pixel shader in registration form gets its pre-rasterization or fragment-shader library built on one background thread, with a fixed state the draw may not use: triangle list, counter-clockwise front face, no depth clamp, depth bias or conservative rasterization, first provoking vertex, one sample. Libraries are kept until the device is torn down; on Astro's Playroom 1948 of them added 0.44 GB of peak memory on RADV.

An unprivileged process cannot raise the hard limit again, so it stays lowered for the process and its threads even when rtkit then refuses the request (burst limit, user or start-time checks) and the thread throws. rtkit's `MaxRealtimePriority` and `RTTimeUSecMax` are read first, so an unreachable rtkit or a priority above its maximum leaves the limit untouched. The lowered limit only matters for threads that later run under a real-time policy
-- AMD image descriptors with `TYPE=0` are treated as null for read-only image slots even when the base and other words are nonzero: `image_load` on a gfx1035 with such a T# returns 0,0,0,0, and the same descriptors were seen in direct reads in PPSA01341 on an RTX 4070.

 - On a device without VK_EXT_robustness2's `nullDescriptor`, such as MoltenVK, a null image descriptor in a typed heap is a [placeholder image](../../../core/libs/prx/libSceAgcDriver/Graphics/src/PlaceholderImages.cpp) of that heap's type, 1×1 and cleared to zero, which every null descriptor of the heap shares. Reads give zeros, as `nullDescriptor` allows, but stores and atomics to it are kept, so a later read of a null storage image can return them, and a depth comparison compares against depth 0. A heap whose placeholder the device cannot create, for example 1D or 3D depth, 64-bit atomics without 64-bit image atomics, or multisampled storage without `shaderStorageImageMultisample`, throws when a null descriptor reaches it.
 - [Draw input snapshots](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver): `PrepareDrawBindings` caps read-only input buffer snapshots at 64 MiB (overridable via `APS5_DRAW_SNAPSHOT_MAX_MIB`). Larger inputs (streaming heaps, bindless pools) or draws exceeding the cumulative budget skip the per-draw snapshot and bind in place, avoiding multi-gigabyte CPU copy stalls (such as Ratchet & Clank: Rift Apart PPSA01474 stalling at frame ~380 copying 36 GB every 5 s). If the title rewrites those large ranges on the CPU before GPU completion, the in-place binding observes the modification, as verified by `drawSnapshotCapTests`.
 - [Pending storage-image results](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) are stored when something reads their memory, not when the GPU work that wrote them completes. A title that waits for that work, frees the image and reuses its memory can have the new data overwritten by the late store (#1970). A title's own CPU reads are not seen either, so a title that reads the results after waiting for a label reads stale memory. `APS5_STORE_AT_FLIP=1` stores every pending result at each flip and `APS5_STORE_AT_LABEL=1` before each label the GPU writes; both store every pending image, not only the ones the waited-for work wrote, and neither is on by default.

Subject: [PATCH 0336/1000] test(agc): delete mapped shader cache entries with
 POSIX semantics on Windows

The disk cache keeps loaded and persisted entries mapped for the life of
the process. On Windows 10 DeleteFileW refuses a file that still has a
mapped view with ERROR_ACCESS_DENIED, so agc_shader_disk_cache failed in
its final remove_all after every check had passed and left its directory
in the temp folder.

Delete each file with FILE_DISPOSITION_FLAG_POSIX_SEMANTICS before
removing the directories, as WriteFileAtomically already renames with
POSIX semantics. The mapped views stay valid, and the test still fails
when a file or the directory cannot be removed. Linux is unchanged.

Subject: [PATCH 0337/1000] perf(recompiler): report which user-data words a
 resource capture only reads through

The SRT evaluator records every raw read with the user-data word its address is
based on, and marks a word used as a plain value. The result also names the
user-data word behind each shader-data dword.

+# Tracing
+
+Set a switch before starting the emulator. Unless noted, any value enables it. Most output goes to the emulator log or standard error. Performance captures are written to files as described in [Build](BUILD.md#performance-trace). Traces can be large and can affect timing.
+
+## Kernel and libraries
+
+| Switch | Output |
+| --- | --- |
+| `APS5_TRACE_AFFINITY` | Thread role, host thread ID, requested CPU mask and whether pinning succeeded. |

+| `APS5_TRACE_BUFFER_WRITTEN` | Guest buffer elements classified as writable or read-only after descriptor population. |
+| `APS5_TRACE_CAPSYNC` | Waits for GPU writes needed by CPU accesses, including submission and range details. |
+| `APS5_TRACE_CONTEXT_STATE` | PM4 context-state operations and registers written while context state is pushed. |
+| `APS5_TRACE_COPY_HLE` | Pending host-side copies, their ranges, GPU batches and known writers. |
+| `APS5_TRACE_DCC_KEYS` | Display and storage-image DCC key reads, writes, fills and clears. |
+| `APS5_TRACE_DISPATCH_CACHE` | Compute dispatch cache hits, misses and changed user-data words. |

+| `APS5_TRACE_QUERY` | Every sixteenth guest-memory page query, including cost and caller address. |
+| `APS5_TRACE_RESOURCE_KEY_MISSES` | Resource-content key changes that cause draw or dispatch resource-cache misses. |
+| `APS5_TRACE_SHADOW` | Unit-shadow publish, seed, eviction and retirement events; a number limits publish output. |

+See [Build](BUILD.md#performance-trace) for the trace format, summary fields and capture limits.
+
+| Switch | Output |
+| --- | --- |
+| `APS5_TRACE_FRAMES=<start>:<count>` | Records a window of presents by zero-based frame number. |
+| `APS5_TRACE_SECONDS=<start>:<length>` | Records a window of presents by elapsed seconds after the first present. Cannot be set with `APS5_TRACE_FRAMES`. |

+| `APS5_TRACE_DIR=<path>` | Writes performance capture and summary files to this directory instead of the working directory. |
+
+## Shader registers
+
+`APS5_TRACE_SHADER_REGS=all` prints register snapshots for every shader. Set it to a shader code address in hexadecimal to print one shader's registers.

Subject: [PATCH 0340/1000] fix(libc): defer resident alias demotion during a
 host write

Retain Pipodi safety guard from closed PR5851 without its resident alias expansion or automatic AGC alias routing. Main still refuses aliases over partial resident runs. Five unmodified-main regression runs fail before this guard; positive validation pending. Fork proposal only; no duplicate upstream PR intended.

Subject: [PATCH 0341/1000] test(libc): retain the open-host-write alias
 regression

Retain the regression originally supplied by Pipodi in closed PR5851 (22091410a), adapted here through e1c6af65b. Current-main-equivalent libc/kernel source returns an alias during the open HostWrite and fails this assertion five times. This test is a reproduction, not a new implementation or an upstream PR.

Subject: [PATCH 0342/1000] perf(agc): find cached draws across moved user-data
 pointers

A draw whose user-data words differ only in pointers the capture read through
looks up an alias key built from the contents behind them, shifts the cached
variant's runs by the pointer delta, validates them by value and patches the
forwarded shader-data words.

Subject: [PATCH 0344/1000] test(agc): a draw whose user-data pointer moved
 reuses the cached draw

A pixel shader loads its colour through a user-data pointer. Drawn from a third address with the same contents it hits the cached draw; with other contents it does not; the addresses seen before still hit exactly.

AI-assisted (Claude Code).

Subject: [PATCH 0356/1000] fix(libkernel): refuse a closed loopback TCP port
 at once on Windows

Windows answers a SYN to a closed port with a RST and then retransmits
the SYN, so connect to a closed loopback port takes about 2 s before
ECONNREFUSED; FreeBSD fails at once. PS5VR (PPSA99177) makes about 33
such connects to 127.0.0.1:17600 and reaches its home screen 45 s late.

When no socket listens on the destination port (GetExtendedTcpTable),
a loopback connect now sets SIO_TCP_INITIAL_RTO with no SYN
retransmissions and fails at once. A port with a listener keeps the
retransmissions: Windows also answers a SYN to a full accept backlog
with a RST, and the retransmission connects once the server accepts,
as the console's does after FreeBSD drops the SYN.

guest_refused_connect requires ECONNREFUSED in under a second for a
closed port through libkernel connect and sceNetConnect, and a second
connect to a listener with backlog 1 to succeed once the server accepts
the first, through both.

PPSA18605 resolves its settings file once, rewrites it one byte shorter and reads it again with the size that resolve returned. The console's behaviour for a read past the end of a file is unverified: it may zero-fill, leave the destination untouched or fail the command

The counters are taken as 32 bits each: the 8-byte access of counter n spans n (low) and n + 1 (high), the 2- and 1-byte accesses select a half or a byte of the counter by its offset, waits compare at the access width (signed and wrapped compares included), the AND mask applies to both sides and the atomic writes wrap within the access.

Recording one needs a read file since the last `ResetGatherScatterState`; like ampr_emu, `sceAmprCommandBufferReset` keeps that state, and a gather or scatter with no read before it in the submitted buffer throws instead of returning `SCE_AMPR_ERROR_APR_INVALIDGATHERSCATTERSTATE`

Not confirmed on a title. The AMM virtual address ranges are a 32 GiB range and a 32 GiB multimap range reserved on first use at the top of the guest arena, above the addresses that maps without `MAP_FIXED` are given lowest first and that titles derive their next hints from; the console's addresses are not known (ampr_emu takes them from `sceKernelMapperGetParam`), and a reservation that cannot be made there throws. Maps outside them throw. Addresses, sizes and direct offsets must be 16 KiB aligned. The memory type and the GPU mask are ignored, AMPR and ACP access maps as CPU access, unmapped pages go back to the pool and stay reserved. Submission runs the buffer before returning, the submit result is always 0 and a failing command throws; the AMM measures return errors sign-extended, as ampr_emu does. A map returns its target to the reservation before releasing the old pages, so pool exhaustion leaves that target reserved; mapping failure also restores the reservation before returning newly taken pages to the pool.

A remap moves every page of a fully mapped range to the new address with the given protection and leaves the old range reserved; a multimap maps the same pages at a second address, anywhere in the AMM ranges, and a pool page goes back to the pool once its last mapping is unmapped; a multimap onto its own source range throws. A protection change sets the masked bits on every page of a fully mapped range; the memory type is recorded and ignored. A command on a range that is not fully mapped throws

Unbacked PRT pages are zero-filled pages with GPU read access, so CPU reads see zeros instead of faulting and GPU writes fault instead of being dropped. `AllocatePaForPrt` backs each unbacked page with a pool page and sets the type and protection of backed ones; `RemapIntoPrt` moves a fully mapped range into a PRT range, its opcode argument (1011 when 0, as in ampr_emu) is recorded and ignored; `UnmapToPrt` returns the pages to the pool and zero-fills them again. A plain map, unmap or remap over a PRT range ends it; `AllocatePaForPrt`, `RemapIntoPrt` or `UnmapToPrt` outside a PRT range throws

The range, protection and mask checks mirror the `libSceAmpr` siblings, and the recorded bytes match them exactly so the submitted buffer executes on the existing paths

Subject: [PATCH 0358/1000] fix(libSceSystemService): give LoadExec's next
 executable the host standard error

A guest dup2 onto descriptor 2 keeps a close-on-exec duplicate of the
host's standard error (#4792), so the runtime's own output stays on the
console while the title's stderr goes where the title pointed it. The
duplicate did not survive LoadExec's execv, and the next executable
started with descriptor 2 still on the title's redirect: its runtime
output, terminate report included, went there.

RetroArch (PPSA99169) points stderr at app0/trace.txt and then starts
its picker. The picker's [gpu] and sceKernelDebugOutText lines landed
in trace.txt, and its abort on an unconverted es-de.bin showed up
nowhere; the message was found only in the core dump.

Before execv, the kept descriptor now goes back onto descriptor 2.

Subject: [PATCH 0359/1000] test(libSceSystemService): check stderr after
 LoadExec of a redirected title

A forked child with stderr on a pipe moves the guest's descriptor 2 to a
second pipe with dup2, then starts itself again through
sceSystemServiceLoadExec("/app0/eboot.bin"). What the new image writes
to stderr must reach the first pipe and nothing the second. It fails
with the previous execv, where the text goes to the guest's pipe.

The main executable is the one `APS5_EBOOT` names, which the first call sets to its own path. After the guest shutdown the old process ends without running guest exit handlers or host destructors. `"exit"` ends the process after the host shutdown without running the title's `atexit` and `__cxa_atexit` handlers, since the console's shell closes the title instead; a line the title writes just before through its own thread, such as a forwarded standard error line, may not be printed.

For such a list Linux replaces the process with `fexecve`: the PID and the standard streams stay, the other descriptors are closed and the working directory becomes the executable's. Windows starts a suspended process that inherits only the standard streams and a handle of the old process, and its entry stub waits for the old process to end before it loads the title's libraries, so a shell or script that started the title sees it end. A null list or one without a first entry keeps the earlier launch: the new executable gets only its own path as its command line (`CreateProcessW` on Windows, `execv` on Linux), so its `argv[0]` is the host path, and the old process ends without waiting for it.

Subject: [PATCH 0361/1000] fix(libSceSystemService): give the host standard
 error back before LoadExec's fexecve

A LoadExec with an argument list replaces the process through Replace (fexecve), which runs before StartHostExecutable, so the next image still wrote to the title's redirect. Descriptor 2 now gets the kept host descriptor there too, after the shutdown and the flush and before close_range closes it.

 LoadExec on both exec paths

The re-executed image is told apart by an environment variable. With an argument list (fexecve) it sees argc 1 and the marker as argv[0]; with a null list (execv) it sees only its path.

 - Windows direct-memory backing reserves a paging-file section. A [direct memory page](../../../core/libs/prx/libc/include/WindowsMappings.hpp) mapped at one guest address is private write-watched memory at that address and is not committed in the section; a page mapped at a second address moves its whole resident run into the section (committed there) and every address becomes a view of it, tracked by write protection. An unmapped resident page that is not all zeros is kept in a private reservation until it is mapped again. Committed section contents remain across unmap/remap and are released when the backing and its remaining views are destroyed. A host import alias over part of a resident run is refused. Linux retains its existing backing. Peak gameplay memory and Windows versions other than the tested host remain unverified.
 - [getc_unlocked, putc_unlocked, getchar_unlocked, putchar_unlocked](../../../core/libs/prx/libc/src/StandardStreams.cpp) (libc) - byte I/O uses the host unlocked operations; guest EOF/error flags and macro counters follow `FileStream`. Linux status queries use `feof_unlocked`/`ferror_unlocked` because [glibc `feof`](https://github.com/bminor/glibc/blob/d2097651cc57834dbfcaa102ddfacae0d86cfb66/libio/feof.c) and [`ferror`](https://github.com/bminor/glibc/blob/d2097651cc57834dbfcaa102ddfacae0d86cfb66/libio/ferror.c) can acquire the stream lock. Windows uses [the CRT no-lock byte operations](https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/fgetc-nolock-fgetwc-nolock) and `feof`/`ferror`, verified under a held stream lock on UCRT. Console behavior and other host CRTs remain unverified.
 - [fgetws, getwc, getwchar, putwc, putwchar](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - wide stream I/O encodes and decodes wide characters as UTF-8 on the underlying byte stream; `fgetws` reads characters into the destination buffer until newline or EOF and null-terminates, returning null on stream error. Console wide stream buffering and encoding details remain unverified.
+- [Closed standard descriptors](../../../core/libs/prx/libc/src/StandardStreams.cpp) (libc) - on Linux and macOS, a descriptor 0, 1 or 2 that is closed when libc loads is opened on `/dev/null` (read-only for 0, write-only for 1 and 2) by a static initializer of libc, which runs before the libraries that depend on libc initialize and before the title starts. Within libc this relies on no static initializer opening a descriptor before it, which `guest_closed_standard_descriptors` checks. glibc does the same for set-user-ID programs ([`check_fds.c`](https://sourceware.org/git/?p=glibc.git;a=blob;f=csu/check_fds.c)). Without it the first descriptor a library opens, the write watch's `userfaultfd` for one, becomes the guest's standard input or output. What the console gives a title as its standard descriptors is not measured, and on Windows a process started without standard handles is not handled.
 - [ftrylockfile](../../../core/libs/prx/libc/src/RuntimeSupport.cpp) (libc) - tries the host CRT stream lock that `flockfile`, `funlockfile` and each locking host stdio call on the stream take, so it returns -1 while another thread holds the stream through `flockfile` or is inside such a call, and 0 when it acquires the lock or already owns it (recursively, released by as many `funlockfile` calls), as FreeBSD 11 [`_ftrylockfile`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdio/_flock_stub.c#L89-L104) does. A libc export holds the lock only for each host call it makes, not across several host calls or while it updates the guest `FILE` prefix. Linux uses glibc `ftrylockfile`. UCRT has no try variant of `_lock_file`, so Windows calls `TryEnterCriticalSection` on the `CRITICAL_SECTION` that `_lock_file` enters, found through the private UCRT stream layout (`__crt_stdio_stream_data` in `ucrt/inc/corecrt_internal_stdio.h`, unchanged from Windows SDK 10.0.19041 to 10.0.26100); another CRT or a change of that layout breaks it. A null or closed stream throws where FreeBSD dereferences it
 - [Wide-character conversions](../../../core/libs/prx/libc/src/Multibyte.cpp) (libc) - The wide `wcsto*` functions parse the ASCII prefix of the guest string, as the C locale accepts only ASCII white space and digits. [`wcsrtombs`](../../../core/libs/prx/libc/src/Multibyte.cpp) uses the guest's single-byte C locale through `wcrtomb`; other encodings and shift states are not supported
 - [realpath](../../../core/libs/prx/libc/src/RealPath.cpp) (libc) follows FreeBSD 11's [`realpath.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libc/stdlib/realpath.c) except for symlinks. The console's guest filesystem has none, so a host symlink under the guest root is followed for existence and type but not expanded, and `..` drops the previous component lexically, as `Resolve` does for every guest path. Through a host link `linkdir -> sub/deep`, `linkdir/../x` gives `x` beside the link, not beside its target.

Subject: [PATCH 0367/1000] fix(agc): stamp the watched blocks of a partly
 watched store

MarkWritten and StoreOwnBytes return 0 for a range that is not wholly
watched, and they stamped none of its blocks. The watched blocks such a
store wrote kept their old stamps, so UnchangedSince and StoredOver over
them still read as unchanged after a GPU write that crossed into an
unwatched import. A vouched shader table column or a cached range then
kept bytes that had been replaced.

Both now stamp each block whose part of the store starts or ends in
watched memory, as the wholly watched path stamps every block. They still
return 0 and note the store as unstamped. This costs one or two coverage
lookups per block, and only on this path.

Subject: [PATCH 0368/1000] test(agc): check the stamps of a store into partly
 watched memory

A driver store and an own store across a watched block and an unwatched
one must stamp the watched block and no other. On Linux, a store across
the halves of a split block must stamp it, and a store into its unwatched
half alone must not.

Subject: [PATCH 0369/1000] feat(libc): ask whether any part of a range is
 write-watched

GuestWriteWatchCovers says whether a range is watched in full. The
Linux and macOS watches unregister page ranges, so a range can hold
watched pages between unwatched ones, and code that must act on every
watched byte of a store has had no way to find them short of asking
page by page. GuestWriteWatchOverlaps answers with one lookup in the
registered ranges, like Covers.

The macOS write-watch test and agc_write_tracking on Linux check it
around watched pages between unwatched ones, at both edges and for an
empty range.

Subject: [PATCH 0370/1000] fix(agc): stamp a block whose watched pages lie
 inside a partly watched store

stampWatchedPart stamped a block when the store's part of it started or
ended in watched memory. That is exact on Windows, where the watch
excludes whole 64 KiB blocks and the arena's host regions are 64 KiB
holes. On Linux and macOS the watch unregisters page ranges, so a
block can be watched only between two unwatched ranges, and a store
across all three left its watched pages with their old stamps.

Off Windows the block is now stamped when the store's part of it
overlaps any watched page (GuestWriteWatchOverlaps). A store that
overlaps no watched page at all returns after that one lookup, where
it made two coverage lookups per block before.

The test watches only the middle pages of a block: a driver store and
an own store around them must stamp it, a store into an unwatched end
must not.

Subject: [PATCH 0371/1000] test(agc): check a store across a watched import
 and one that left the watch

Since #6060 a settled Windows host import of private write-watched
memory stays watched, and its bytes are vouched by the write tracker's
stamps instead of compared. A GPU write that runs from such an import
into a neighbouring import that left the watch reaches the tracker as
one MarkWritten over a partly watched range. The test imports two
blocks that stay watched next to one that leaves the watch, and checks
that a driver store and an own store across the boundary stamp the
watched block they wrote, are seen over exactly its stored bytes, and
leave the other watched block unchanged.

Subject: [PATCH 0374/1000] fix(libSceAudioOut): count completed AudioOut2
 grains in the queue level

sceAudioOut2ContextGetQueueLevel left out the grains that
sceAudioOut2ContextAdvance completed and no push had consumed yet. While
pushes filled the 40 ms cushion the level stayed at 0, so a title that
renders as many grains as the level leaves room for and pushes them on
another thread rendered a full queue again after each push. PPSA23226's
Wwise sink does that and stopped once more than 16 completed grains
awaited a push.

 - [sceAudioOut2EnableChat](../../../core/libs/prx/libSceAudioOut/src/AudioOut2System.cpp) (libSceAudioOut) takes no arguments and returns 0, as declared by [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Audio/AudioOut2.cs#L460-L464) ("Allows chat audio alongside the application's own"). The host mixes no chat audio and AudioOut2 has no chat port, so the call only records that chat audio is allowed. Whether the console fails it without a chat session, when repeated or before `sceAudioOut2Initialize` is unknown. [sceAudioOut2DisableChat](../../../core/libs/prx/libSceAudioOut/src/AudioOut2System.cpp) is the counterpart, imported by PPSA18216: it takes no arguments, returns 0 and records that chat audio is no longer allowed; its signature is not confirmed by a console measurement, and whether the console fails it without a chat session or when repeated is unknown.
 - [sceAudioOut2Set3DLatency](../../../core/libs/prx/libSceAudioOut/src/AudioOut2System.cpp) and [sceAudioOut2MasteringInit, sceAudioOut2MasteringTerm and sceAudioOut2MasteringSetParam](../../../core/libs/prx/libSceAudioOut/src/AudioOut2Mastering.cpp) (libSceAudioOut) have no effect: there is no 3D rendering or mastering stage.
 - [AudioOut2 contexts](../../../core/libs/prx/libSceAudioOut/src/AudioOut2Context.cpp) (libSceAudioOut) with an SDL device and no `sceAudioOut2ContextAdvance` calls read a grain's port buffers at the next push, at least 100 us after the grain was pushed, and play the mix behind a 40 ms cushion that the queue level leaves out. When the hardware reads the buffers is not known. The timing follows a title whose mixer fills a buffer after pushing it, reuses it two pushes later, and may still be writing it when the next push follows within microseconds. The last grain pushed before a title stops pushing is never read or played.
+- [sceAudioOut2ContextGetQueueLevel](../../../core/libs/prx/libSceAudioOut/src/AudioOut2Context.cpp) (libSceAudioOut) with an SDL device counts the grains that `sceAudioOut2ContextAdvance` completed and no push has consumed as queued, together with the pushed grains beyond the 40 ms cushion, up to `queue_depth`. Whether the console counts them is unknown. Pushes that fill the cushion leave the level at 0, so a title that renders as many grains as the level leaves room for and pushes them on another thread rendered a full queue again after each of those pushes: PPSA23226's Wwise sink passes the available count to the sound engine as the number of frames to render, advances once per frame and pushes on a separate thread, and exceeded 16 completed grains. Counted, the completed grains keep such a title at most `queue_depth` grains ahead of its pushes.
 - [sceAudioOutSysGetHdmiMonitorInfo](../../../core/libs/prx/libSceAudioOut/src/AudioOut.cpp) (libSceAudioOut) reports an HDMI sink without a monitor name or audio descriptors: it zeroes the 0x180 bytes and returns 0, since audio reaches the host through SDL as PCM and there is no EDID to describe. The arguments `(type, info, size)`, the required size 0x180 and the fields titles read (monitor name at +0x0B, 13 bytes; descriptor count as a 32-bit value at +0x94; 8-byte descriptors `[coding type, channels, rate mask, 0, extra, 0, 0, 0]` from +0x98) come from [PS5-Audio-Passthrough-Research](https://github.com/sainsaji/PS5-Audio-Passthrough-Research/blob/c3be9c2afcb8f7838784ead0fe1c12a2ceea965a/docs/FINDINGS.md) (firmware 12.70, one monitor). What a console without an HDMI audio sink returns, an error or no descriptors, is unknown. The other bytes, among them the header at +0x90 (`01 09 4f 00` on that monitor), have no known meaning and are written as 0. No LPCM descriptor is reported for the host device, as the rate mask and extra byte of one are not known. A null buffer returns `0x80260004` like the other AudioOut calls; the console's code is not measured. Monitor type 0x10, which the console also accepts, other types and sizes other than 0x180 throw: their results and error codes are unknown.

Subject: [PATCH 0376/1000] fix(agc): keep each set's image table writes in its
 own draw snapshot set

The vertex and fragment image tables both sit at ImageTableBinding, in
sets 0 and 1. PrepareDrawBindings matched the recorded writes to their
bindings by binding number alone, so the set 0 table also took the
fragment table's writes: they went into the snapshot's set 0, past its
variable descriptor count and into the next set in the pool, and the
snapshot's set 1 table was left unwritten.

Match a write by its original set as well. The recorder test device now
enables the descriptor indexing features image tables need.

Subject: [PATCH 0377/1000] fix(agc): accept a copy's sample selection on a
 draw that copies nothing

DB_RENDER_CONTROL.COPY_CENTROID and COPY_SAMPLE select the sample that
DEPTH_COPY or STENCIL_COPY copies. Forspoken (PPSA03984) draws with
DB_RENDER_CONTROL 0xc0, DEPTH_COMPRESS_DISABLE and COPY_CENTROID with
neither copy bit set, and stopped at 43 s because both
DepthMaintenanceRejection and decodeDepth took the selection for a copy.

Accept the selection fields when no copy is enabled; draws that copy are
still rejected.

Subject: [PATCH 0378/1000] fix(agc): treat a view past a depth surface's first
 level as memory

A depth surface is one level: the driver rejects draws that render a
depth mip. A sampled or storage view at the surface's address and extent
that starts at a later level, or a storage access to a later level, does
not touch that level, so it is not the depth plane. DepthSurfaceTexture
and DepthSurfaceStorage still sent such views to the surface, which
rejected the level. Forspoken (PPSA03984) builds a depth pyramid from its
1984x1116 D32 depth surface with a compute shader that samples one level
of a five-level R32F view and stores the next, and stopped there.

Both now leave such views to the texture and storage caches, as they
already do for a view of another extent or format.

Subject: [PATCH 0379/1000] fix(agc): drop resource-cache entries that hold
 released sampled textures

A resource-cache entry keeps every sampled texture of its descriptor sets alive. The sampled texture cache passes over textures something else holds and, past its ceiling, drops them anyway; textures it makes without caching are never in it. Entries holding either kept them alive with no budget counting them, bounded only by the 1,024-entry and 65,536-element counts, until device memory ran out.

The texture cache now marks such textures released. ResourceCache::Insert refuses descriptor sets holding one and hands the entries that hold one back to the caller, like RemoveImage does for evicted storage images.

 - [Flip packets raise the graphics end-of-pipe event](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Packets/PacketExecution.cpp) (libSceAgcDriver) - a flip delivers the queue's end-of-pipe event (`sceAgcDriverAddEqEvent`) once the work recorded before it completes, as a `RELEASE_MEM` with `INT_SEL` does. Minecraft (PPSA17221) registers the graphics event, never requests an interrupt in its releases, and waits on the event after every flip while holding its render lock, so without this it never presents a second frame. Whether the console raises the event from the flip itself or from an interrupt its flip sequence contains is not measured; a title that waits only on release interrupts sees one extra event per flip, with `data` counting it.
 - [Host import windows and budget](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): a registered range larger than 64 MiB is imported one 64 MiB window at a time for buffer and fill accesses; an access across window edges imports the cells it touches, grown to the union of the range's imports it overlaps. An address-based build (`AcquireRegistered`) imports the range whole and replaces its windows. Live imports stay under a budget: `APS5_HOST_IMPORT_MIB`, else the larger of 6 GiB and half the physical memory, at most the largest host heap less 2 GiB (imports and type-3 mirrors share it; #167's rule). A new import beyond it retires the least recently used imports not used in the last 256 lookups; one that would not fit even then is refused before anything is retired, and imports made when a range is mapped never evict. A refused import is tried again at its next use. The 64 MiB window, the 256-lookup protection and the 2 GiB reserve are choices, not measured.
 - [Registration preparation at submit](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Queues/Submission.cpp) (libSceAgcDriver) - `Driver::Submit` waits for every registration-time shader preparation queued before the call, not only those of the shaders the commands use, so a submission behind a long queue of unrelated preparations waits for all of them on the submitting thread. Waiting there instead of in the queue worker keeps the GPU side of a submission short: a title that sees a submission take seconds treats the GPU as hung (Goat Simulator 3, PPSA04159, then stops submitting and its garbage collector fails a 10 s timeout). On the console shaders are compiled ahead of time, so neither wait exists; how long a title tolerates a slow submit call is not known.
+- [Resource cache entries holding released textures](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - a sampled texture the texture cache drops while something else holds it, or makes without caching (`admitTexture` refusing a first use), is marked released, and `ResourceCache::Insert` refuses descriptor sets that hold one and removes the entries that do. The removal waits for the next insert: until then `Find` still returns those entries and their textures stay alive. One process-wide flag starts the sweep, so while the sampled cache is over its budget every insert scans all entries (up to 1,024, each with its textures); that cost is not measured. A draw or dispatch whose textures the cache refused builds its descriptor sets again on each use for as long as the cache stays full; the count bounds (`APS5_RESOURCE_CACHE_ENTRIES`, `APS5_RESOURCE_CACHE_TABLE_ELEMENTS`) still bound nothing by bytes, and sampled textures made outside the texture cache (the disabled cache, depth-surface copies) are never marked. Measured only on Ghost of Yōtei (PPSA26344), and before this change with the env bounds lowered as a stand-in: with 256 entries and 16,384 table elements, sampled textures held outside the cache fell from up to 7,830 MiB to 2,541 MiB at the wolf scene and device-local heap 0 stayed under its 23 GB budget.

 - [Flip packets raise the graphics end-of-pipe event](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Packets/PacketExecution.cpp) (libSceAgcDriver) - a flip delivers the queue's end-of-pipe event (`sceAgcDriverAddEqEvent`) once the work recorded before it completes, as a `RELEASE_MEM` with `INT_SEL` does. Minecraft (PPSA17221) registers the graphics event, never requests an interrupt in its releases, and waits on the event after every flip while holding its render lock, so without this it never presents a second frame. Whether the console raises the event from the flip itself or from an interrupt its flip sequence contains is not measured; a title that waits only on release interrupts sees one extra event per flip, with `data` counting it.
 - [Host import windows and budget](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): a registered range larger than 64 MiB is imported one 64 MiB window at a time for buffer and fill accesses; an access across window edges imports the cells it touches, grown to the union of the range's imports it overlaps. An address-based build (`AcquireRegistered`) imports the range whole and replaces its windows. Live imports stay under a budget: `APS5_HOST_IMPORT_MIB`, else the larger of 6 GiB and half the physical memory, at most the largest host heap less 2 GiB (imports and type-3 mirrors share it; #167's rule). A new import beyond it retires the least recently used imports not used in the last 256 lookups; one that would not fit even then is refused before anything is retired, and imports made when a range is mapped never evict. A refused import is tried again at its next use. The 64 MiB window, the 256-lookup protection and the 2 GiB reserve are choices, not measured.
 - [Registration preparation at submit](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Queues/Submission.cpp) (libSceAgcDriver) - `Driver::Submit` waits for every registration-time shader preparation queued before the call, not only those of the shaders the commands use, so a submission behind a long queue of unrelated preparations waits for all of them on the submitting thread. Waiting there instead of in the queue worker keeps the GPU side of a submission short: a title that sees a submission take seconds treats the GPU as hung (Goat Simulator 3, PPSA04159, then stops submitting and its garbage collector fails a 10 s timeout). On the console shaders are compiled ahead of time, so neither wait exists; how long a title tolerates a slow submit call is not known.
-- [Resource cache entries holding released textures](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - a sampled texture the texture cache drops while something else holds it, or makes without caching (`admitTexture` refusing a first use), is marked released, and `ResourceCache::Insert` refuses descriptor sets that hold one and removes the entries that do. The removal waits for the next insert: until then `Find` still returns those entries and their textures stay alive. One process-wide flag starts the sweep, so while the sampled cache is over its budget every insert scans all entries (up to 1,024, each with its textures); that cost is not measured. A draw or dispatch whose textures the cache refused builds its descriptor sets again on each use for as long as the cache stays full; the count bounds (`APS5_RESOURCE_CACHE_ENTRIES`, `APS5_RESOURCE_CACHE_TABLE_ELEMENTS`) still bound nothing by bytes, and sampled textures made outside the texture cache (the disabled cache, depth-surface copies) are never marked. Measured only on Ghost of Yōtei (PPSA26344), and before this change with the env bounds lowered as a stand-in: with 256 entries and 16,384 table elements, sampled textures held outside the cache fell from up to 7,830 MiB to 2,541 MiB at the wolf scene and device-local heap 0 stayed under its 23 GB budget.

Subject: [PATCH 0383/1000] fix(relinker): search libc.prx for libkernel-only
 Windows executables

AnyPS5 exports some libkernel functions, such as __error, from
libc.prx, which libkernel.prx links. On Linux they resolve through that
dependency. On Windows, the import stubs search only the listed
modules, and libc.prx was listed only when libSceLibcInternal.prx was
needed. A PS4 homebrew that needs libkernel.prx but no C library (the
OpenOrbis graphics sample) failed with "unresolved ELF import
9BcDykPmo1I". libc.prx is now also listed when libkernel.prx is needed.
PS5 executables need libSceLibcInternal.prx and convert unchanged.

+- On macOS, [libc.prx](../../../core/relinker/elfpatcher/src/macos/MacOsMachOPatcher.cpp) is a dependency only when `libSceLibcInternal.prx` is needed, so a program that needs only `libkernel.prx` cannot resolve the libkernel functions that AnyPS5 exports from libc.prx, such as `__error`. Windows also lists libc.prx for `libkernel.prx`.

Subject: [PATCH 0384/1000] fix(agc-driver): keep storage images with pending
 results out of the memory release

Storing a storage image's pending results needs a staging buffer, and under memory pressure that buffer comes from the heap whose allocation just failed. The release turned to dirty images once the clean ones did not cover the request, so with the device and shared heaps full it failed on a 4 MiB write-back buffer at every call (PPSA26344 on Windows). StorageTexture::Flush clears the pending state before it stores, so each failed store also dropped that image's results. The release now takes only sampled entries and storage images without pending results, and its line reports how many images with pending results it kept.

Subject: [PATCH 0386/1000] perf(agc): allow shader preparation on first use

APS5_LAZY_SHADER_PREPARE=1 keeps registration validation and decoding but skips queueing the preparation. Draws and dispatches prepare a deferred snapshot on first use and cache it; explicit ABI resolution still prepares its stages. Titles that register thousands of shaders at boot no longer hold every prepared shader in memory before the first frame.

Cover lazy dispatch, metadata and failure cases in both asynchronous and synchronous modes.

 - Queue 0's packet worker decodes, captures and prepares a draw and hands its recording (`Graphics::Draw` under the GPU lock) to a committer thread in [`DrawPipeline.cpp`](../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Draw/DrawPipeline.cpp), so the next packet is decoded while the previous draw is recorded. Each queued item carries the guest ranges it will write (`DrawWriteRanges`: written buffers and storage images, color targets with their DCC and CMASK, depth and stencil). A later packet that reads or writes one of those ranges, or that the pipeline can't order, drains it first; labels, submission ends, buffer fills and (with `APS5_PIPELINE_DMA=1`) DMA packets are queued as items instead. An exception thrown by a commit is rethrown on the worker at its next enqueue or drain, as an inline draw error would be. On by default; `APS5_PIPELINED_DRAWS=0` records every draw inline, and `APS5_EXACT_DRAW_WRITES=0` widens the color and depth ranges to estimates.
 - The shader registry maps a code address to every header registered for that code, in registration order. Static, graphics and rectangle ABI resolution pick the header at the bound address (or one equal to it, `SameHeader`, which also takes a hull header fused by `sceAgcFuseShaderHalves` (type 3) as the registered back half (type 7) it copies, the fused registers aside; graphics ABI resolution then uses the fused header's shader registers); draws and dispatches pick the program by the stage's binary type (`RegisteredProgram`), and a front entry matching both type 2 and type 4 throws. Within a type the last registration wins; re-registering an identical earlier header makes its snapshot current again without preparing it again, and changed code drops the older headers.
 - The snapshot is published as pending. `SourceHandleFor`, `InvocationFor` and `ShaderPreparationTransaction::Edit` / `Read` wait for the pending job before reading `PreparedShaders`, and rethrow its failure. `APS5_SYNC_SHADER_PREPARE=1` prepares on the registering thread instead.
+- `APS5_LAZY_SHADER_PREPARE=1` retains registration validation and decoding but discards the temporary plan without queueing preparation. The snapshot is deferred, not pending; draws and dispatches prepare and cache it on first use. Explicit ABI resolution still prepares its requested stages. This opt-in mode takes precedence over synchronous registration preparation and trades background CPU/memory use for possible first-use stalls; disk caches and shader output are unchanged.
 - On devices with graphics pipeline libraries (`SpirvTarget::registrationModules`), a vertex or pixel artifact is emitted in registration form: the buffer V# words, image modes, swizzles and mip ranges, depth-compare state, export mappings and vertex component selectors it used to specialize on per draw are read at run time (image `ResourceMetadata` and a few state dwords in the shader data), descriptor heaps keep every element in place (an unused one gets a null or placeholder descriptor), and the pixel stage's bindings live in descriptor set 1 so each stage's library depends only on its own set layout (`INDEPENDENT_SETS`). An artifact above `registrationWordLimit` SPIR-V words is re-emitted specialized, and `CompiledShaderArtifact::registrationModule` records which form it has. For artifacts in registration form, `RegistrationResult` materializes the module once, and `PrebuildStageLibrary` builds its pre-rasterization or fragment-shader library on a separate one-thread pool (`APS5_PREBUILD_THREADS`) with a fixed default state, pairing it with a stub stage. A later draw with that state finds both libraries in the store and only links.
 - A draw or dispatch whose state matches no artifact prepared at registration (a title that builds its static ABI state itself, without `sceAgcDriverResolve*Abi`) gets one prepared at use by `SourceHandleFor` or `InvocationFor`, logged once per artifact and kept in the snapshot for the next use.
 - A compute shader whose `s_swappc_b64` calls a user-data pointer cannot be linked at registration, because the callee's address is only known at dispatch. `InvocationFor` in [`ShaderRegistry.cpp`](../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Shaders/ShaderRegistry.cpp) reads each callee from guest memory, appends one copy per call after the caller (`LinkUserDataCalls`) and prepares that linked code, so a different callee gets its own prepared entry.

Subject: [PATCH 0387/1000] test(agc): check that lazy registration defers
 preparation

The lazy mode of agc_driver_prepared_shaders only checked dispatch output and failure reporting, which eager preparation also produces. Read the registered snapshot through Driver::RegisteredShaders: registration leaves it deferred with no prepared artifact, and the first dispatch prepares it.

 - [gethostname](../../../core/libs/prx/libc/src/Hostname.cpp) (libc) reports the fixed guest name `AnyPS5` without querying the host machine name. Buffer copying, null queries and `ENAMETOOLONG` follow [FreeBSD gethostname](https://github.com/freebsd/freebsd-src/blob/main/lib/libc/gen/gethostname.c); the console's configurable hostname and its integration with `sysctl` and name resolution are unverified and not implemented.
 - [wcsrtombs_s](../../../core/libs/prx/libc/src/Multibyte.cpp) (libc) follows the console's `libc.prx`, but a runtime-constraint violation only returns its error: the default handler there writes the message and a newline to `stderr` before returning, which is not done here. Conversion uses the C locale of `wcrtomb` (`MB_CUR_MAX` 1), so the path where a multibyte character does not fit the remaining space is not reached
 - [The narrow printf family](../../../core/libs/prx/libc/src/Formatting.cpp) (libc) converts 16-bit guest wide arguments to UTF-8 on both platforms, independently of the host locale. It does not use the guest's single-byte `wcrtomb`; the console's treatment of invalid UTF-16 and locale-specific encoding remains unverified. Linux retains host formatting for formats without wide arguments or `%m`, so a narrow `%p` and a NaN there still follow the host (glibc prints a null pointer as `(nil)`, where FreeBSD prints `0x0`, and a NaN with its sign, `-nan`, and with the `+` and space flags, where FreeBSD prints `nan`); argument positions above 99 (FreeBSD's `NL_ARGMAX`) throw when a format requires the guest formatter
-- [collate<char> and collate<wchar_t> _Getcat](../../../core/libs/prx/libc/src/LocaleSupport.cpp) (libc) build the facet for the C locale only and throw for any other locale name, the wide entry point following the narrow one it sits next to. The wide facet carries its own vtable, whose `compare`, `transform` and `hash` take the guest's 16-bit characters, so the length of a range is a count of characters: `compare` orders by 16-bit value (the C locale, as Dinkumware's `char_traits<wchar_t>::compare` does), `transform` copies the characters into the result as the guest's bytes and sizes the result in bytes (two per character, a 16-bit terminator, the 7 characters that still fit next to it and `length * 2 | 15` plus two bytes of storage beyond that), and `hash` mixes one whole character per round, so wide text below 0x100 hashes like its narrow spelling and a character above 0xff hashes as one value instead of the two bytes it holds. The console's `libc.prx` exports both `_Getcat` (NIDs BSVJqITGCyI and 2wz4rthdiy8) with identical 0x19d-byte bodies, believed to build the same 0x20-byte facet; the console bodies themselves are unreadable (obfuscated dynsym, and the text of the relinked `libc.prx` is zeroed), so the wide entries follow the narrow algorithm and the C locale instead of the console's wide code, and no console run checks the two. The console's `libc.prx` stores pointers to its collation state tables at offsets 0x10 and 0x18 of the facet; ours leaves them null, as only the facet's own functions read them. `do_transform` throws for input with embedded null characters, which the console drops depending on the output buffer size. The narrow result capacity (`length | 15`) and the over-aligned storage of results of 4080 characters or more follow the console's `libc.prx` code and are not checked on hardware. No module of the PPSA59322, PPSA76677 or PPSA97358 dumps in this tree imports either `_Getcat`, so neither has been exercised by a title.

 - [The scanf family](../../../core/libs/prx/libc/src/Formatting.cpp) (libc), the `_s` forms included, on Linux throws for the 16-bit wide conversions (`%ls`, `%lc`, `%l[`, `%S`, `%C`): glibc would store a 32-bit `wchar_t` per character into the guest's 16-bit buffer. Windows hands `%ls`, `%lc` and `%l[` to the host, whose `wchar_t` is 16 bits
 - [The scanf family](../../../core/libs/prx/libc/include/WindowsScanning.hpp) (libc) on Windows returns 0, as C17 and FreeBSD do, when input fails after only suppressed conversions have completed (`sscanf("12", "%*d%d", &value)`). Linux hands the format to glibc, which returns `EOF` there. On Windows the host stops a `%x`, `%X`, `%i` or `%p` after the `x` of a `0x` that no hex digit follows (or that the width cuts off), and a float conversion (`%e`, `%f`, `%g`, `%a`) after the `e` of an exponent with no digits (`1e`), where C17 and FreeBSD stop before the `x` or the `e`
 - [Guest path resolution](../../../core/libs/prx/libc/src/General.cpp) falls back to ASCII case-insensitive component lookup, following [shadPS4's host filesystem](https://github.com/shadps4-emu/shadPS4/blob/945dbc3cc3eee80ac3e053b438502ed936fa6bb2/src/core/file_sys/backends/host_fs.cpp). PPSA03747 requests `Skyrim.INI`, `Data/Video` and lowercase archive/plugin names that differ from the dump's filenames. Exact host names take precedence; multiple fallback matches throw instead of selecting an arbitrary file. Existing parent names are resolved when creating a new file, and guest mount aliases use the same ASCII comparison. Results are not cached, so renames and newly created files remain visible. Unicode case folding and PS5 behaviour for case-colliding host entries are unverified; host roots are used as supplied. Explicit native Windows drive and UNC paths bypass guest parent-component validation.. A relinked module's `<name>.guest.prx` is matched the same way when the original module is not beside it: Borderlands 4 (PPSA01494) loads `/app0/prx/libRenoirCore.PS5.prx`, which it ships as `librenoircore.ps5.prx`

The prototype is not documented. PS5LM Plus (PPSA99581) passes a zeroed 128-byte buffer and, on success, reads its first 32-bit word as milliwatts, accepting 1000 to 350000; on failure it shows 0 W
 - [scePthreadMutexattrSetprotocol](../../../core/libs/prx/libkernel/Pthread/src/Mutex.cpp) (libkernel) - accepts 0 to 2 as a PS5 (firmware 13.60) does and returns `EINVAL` otherwise, but the protocol is not stored or applied: priority inheritance and protection are not modelled. On the console a null or uninitialized mutex attribute returns `EINVAL` from the SCE attribute calls, `scePthreadMutexInit` takes an uninitialized attribute as the default one, and a destroyed mutex returns `EINVAL` from `scePthreadMutexDestroy`; a null mutex pointer crashed the payload and still throws

A null, uninitialized or destroyed attribute returns `EINVAL` before the other arguments are checked; this error behavior is unverified on the console.

The PS5's SoC id and CPU mode are unknown; shadPS4's PS4 values are [0x710f10/0x740f30 and 0, 2 or 5 from the param.sfo CPU-mode flags](https://github.com/shadps4-emu/shadPS4/blob/e0a466753a1a/src/core/libraries/kernel/process.cpp).

The no-argument `int` signature follows shadPS4 and ProsperoEden (PPSA99008), which calls it before mapping the same direct memory again. Whether the PS5 refuses such a mapping without the call is unverified
 - [sceKernelInternalMemoryGetAvailableSize](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) (libkernel) reports 0 bytes and returns 0: what the console's internal memory pool holds and how large it is are unknown. The `int (size_t*)` signature is from [xUtilty](https://github.com/Backporter/xUtilty/blob/328a856af1ef/source/SystemWrapper.cpp#L85) (PS4). PPSA99203 calls it once beside `sceKernelAvailableFlexibleMemorySize` while starting its GS renderer and never reads the result ([GS.cpp](https://github.com/Swordpdf/PS5SX2/blob/b4cf55e87c34/pcsx2/GS/GS.cpp#L233-L247))

Subject: [PATCH 0391/1000] test(relinker): execute the AMD64-only conversion
 stubs on macOS

The execution part of the AMD64-only converter tests was compiled for
Linux x86-64 only, so the SSE4A, SHA-1, SHA-256, CLZERO and reciprocal
stubs were never run on a macOS x86-64 build, unlike the ANDN lowering
tests. Rosetta maps no memory below 4 GiB, so the CLZERO case that needs
a 32-bit address is left out when that mapping is unavailable.

Subject: [PATCH 0392/1000] perf(agc): format and write steady-state log lines
 off the queue worker

Texture creation logged one stdout line per texture and per mip through
WriteLogLine, which formatted with the mingw printf and flushed every
line on the queue worker (about 786k lines in a 25 minute cave run).

AsyncLog keeps a bounded queue and a logger thread. AGC_LOG_DEFERRED
captures numeric arguments on the caller and formats them on the logger
thread; WriteLogLine hands finished lines to a per-module sink in
libc/LogMacros.hpp that AgcDriver installs, so all AgcDriver stdout
lines keep their order and are written one flush per batch. A full queue
blocks the caller, so no line is dropped. Flush runs on driver failure,
shutdown and at exit. APS5_LOG_SYNC=1 restores the synchronous path.

Identical "deferred write-back failed" notes are printed three times per
10 s and then counted into one "repeated N more times" line. A
"[log] 10 s" line reports lines, bytes, caller time and logger time
(APS5_LOG_STATS=0 hides it).

Subject: [PATCH 0394/1000] test(agc): Flush waits for a held stream and a full
 queue blocks the caller

Flush must not return while the logger still waits for a stream that
another thread holds (the regression reported on the pull request: it gave
up after two seconds), and a full queue must block its caller instead of
dropping a line. AsyncLog::Capacity becomes public so the test sizes its
load from it.

Subject: [PATCH 0395/1000] fix(agc): flush the log queue, bounded, where the
 process ends without exit handlers

Lines queued behind the logger were lost when the process ended through
abort(), std::terminate, the Windows crash report or a guest _Exit,
because only driver failure, Driver::stop and a normal exit flushed the
queue.

libc keeps one end flush (LibcSetEndFlush_nid_no_patch) and runs it from
those paths. Its first registration chains a SIGABRT handler in front of
the previous one, so every abort() and std::terminate in the process is
covered, on Linux as well; with the default disposition the handler
restores it and raises again, so raise(SIGABRT) still ends the process.
Guest abort() and _Exit, and ReportCrash for the first fatal exception,
run the flush directly. AsyncLog registers a bounded flush (FlushFor, 2 s)
that polls two counters and takes no lock, so a dying process cannot hang
on a blocked stream or on the queue lock; after its first timeout it
returns at once. Flush counts queued and finished entries instead of
watching the queue and the writer flag, so it waits for the lines queued
before the call and not for a moment in which no thread is logging.

agc_async_log_fatal runs the test executable as a child that queues lines
behind a held stream and ends in abort(), std::terminate(), raise(SIGABRT)
(POSIX) or an access violation (Windows), and once more with the stream
never released. The lines of the first four must arrive in order, the last
child must end after the bound, and every child has a watchdog.
agc_async_log gains the bounded flush case.

Subject: [PATCH 0396/1000] docs: describe the log queue, its flush points and
 the stream order in ARCHITECTURE.md

The logger thread, the bounded queue that blocks its caller, the LogSink
hook, APS5_LOG_SYNC and APS5_LOG_STATS, where the queue is flushed and
what stays outside it: direct fprintf(stderr) and printf calls are written
at once, so they can appear before older queued lines.

 - Guest memory reaches the GPU through host imports (`VK_EXT_external_memory_host`) where the driver accepts them, and through copies otherwise ([`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp)). A registered range larger than the import window (64 MiB) is imported per window for buffer and fill accesses and whole for an address-based build. Live imports stay under a budget, with the least recently used import retired first (see TechnicalDebt, Host import windows and budget).
 - On Windows, a host import of private `MEM_WRITE_WATCH` memory (singly mapped direct memory) stays on `GetWriteWatch` when `ProbeImportWriteProtection` shows the driver reports nothing written after the second GPU read and a GPU write, and a CPU store is collected (`decideImportWatch`). The driver marks every page of such an import written, asynchronously, until its first GPU use completes, so `settleImport` in [`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) copies 4 bytes out of the new import on a second queue of the graphics family, or on a queue of another copy-capable family when the graphics family has only one (`Context::settleQueue`, own pool and mutex) inside `ImportWatched`'s window and waits for it, only for imports of 1 MiB or more (a smaller import is compared, so a title that maps, imports and unmaps a small buffer around every submission does not block its mapping thread); the main queue can't be used there because `importAllocation` holds the imports lock and `GpuMutex` comes before it in the lock order. Imports through a section alias keep tracking on the guest views, and every other Windows host import is compared. A device without such a queue keeps the comparisons.

+
+`WriteLogLine` ([`LogMacros.hpp`](../../core/libs/prx/libc/include/general/LogMacros.hpp), behind `APS5_LOG_OUT` and `APS5_LOG_ERR`) formats a line on the calling thread and hands it to the module's `LogSink()` when one is installed; without a sink it writes and flushes it there. `Driver` installs [`AsyncLog`](../../core/libs/prx/libSceAgcDriver/Execution/include/AsyncLog.hpp) as the sink of `libSceAgcDriver`, so the queue workers no longer wait for the console or the log file for those lines. `APS5_LOG_SYNC` (any value) skips the installation and restores the synchronous path.
+
+- **Queue.** One logger thread drains a queue that holds at most 16 MiB of waiting lines; the batch the logger is writing comes on top. A caller that finds the queue full blocks until the logger has taken the pending batch, so no line is dropped. The logger writes entries in queue order and joins consecutive entries of one stream; it writes them with one `fwrite` and flush when the text reaches 64 KiB, the stream changes or the batch ends. `AGC_LOG_DEFERRED` queues the format string with numeric, enum and `LogLiteral` arguments and formats them on the logger thread; `APS5_LOG_TIMESTAMPS` stamps a line when it is queued.
+- **Order.** Lines that pass through the sink, on stdout and stderr alike, appear in call order. A direct `fprintf(stderr, ...)` or `printf` does not pass through it and is written at once, so it can appear before older queued lines; the coalesced `deferred write-back failed` notes are of this kind. `APS5_LOG_SYNC=1` keeps one order for all of them.
+- **Flush.** `Flush` waits without a limit until every line queued before the call has been written, including while another thread holds the stream. It runs when the driver fails, in `Driver::stop` and at exit. `AsyncLog` also registers a bounded flush (`FlushFor`, 2 s) with `LibcSetEndFlush_nid_no_patch`; libc runs it where the process ends without those: `abort()` and `std::terminate` (a `SIGABRT` handler that the first registration chains in front of the previous one, so `raise(SIGABRT)` still ends the process), guest `abort()`, the Windows crash report of a fatal exception and guest `_Exit`. A title that installs its own `SIGABRT` disposition replaces that handler. The bounded flush polls two counters and takes no lock, so a thread that dies holding the queue lock or a stream cannot stall it. After 2 s it gives up, later calls return at once, and the lines still queued are lost.
+- **Statistics.** A `[log]` line every 10 s in which lines were logged reports lines, bytes, the time spent by the callers and by the logger, and the queue peak; `APS5_LOG_STATS=0` hides it. Identical `deferred write-back failed` notes print three times per 10 s and are then counted in one `repeated N more times` line.
+
+`agc_async_log` checks the order of deferred and written lines, long lines, the repeat limit, a `Flush` that waits for a held stream, a bounded flush that gives up, and a full queue that blocks its caller. `agc_async_log_fatal` starts the test executable as a child that queues lines behind a held stream and then calls `abort()`, calls `std::terminate()`, raises an access violation (Windows) or `SIGABRT` (elsewhere), or aborts without ever releasing the stream; the first four must leave every line in the file in order, the last must still end after the bound.
+
 ### Runtime image and sampler tables
 
 A T# or S# that a shader loads from a buffer at a runtime offset (`key * stride + addend`, or `(key << n) & mask`) is not a direct descriptor. [`ResourceTracker.cpp`](../../core/shader/recompiler/Optimization/src/ResourceTracker.cpp) plans it as a table column (`TableColumn`): the heap V#'s descriptor source, the record stride and addend, the descriptor's offset in the record, and the key domains that may narrow it. Accesses with the same heap and record shape share one column. The shader keeps computing the offset and indexes a table binding: images use one variable-count `SAMPLED_IMAGE` array (`RuntimeAbi::ImageTableBinding`, in the fragment set when pipeline libraries split the sets), samplers a `SAMPLER` array (`Binding::SamplerTable`). Devices without `runtimeDescriptorArray`, `descriptorBindingPartiallyBound` and `descriptorBindingVariableDescriptorCount` refuse such shaders.

Subject: [PATCH 0397/1000] fix(agc): a relocation trial counts the hits the
 verification captured again

With APS5_VERIFY_DRAW_ENTRIES=1 every hit is captured again, so drawHit is false and no relocated hit counted for its shader set's trial, which judged every set unproductive and turned the relocation off under the very mode meant to check it.

Subject: [PATCH 0398/1000] fix(nid): reject ELF exports that patch to
 different symbols under one name

Two defined ELF exports that are renamed to the same name, such as foo
and foo_nid_disambig1, were both written as one name and the patcher
exited 0, leaving a lookup that can reach only one of them. The PE and
Mach-O back ends already reject this.

The ELF patcher now remembers the address (st_value and st_shndx) of
each patched export name and throws "duplicate patched export name"
only when the name comes from a symbol at a different address. Aliases
of one address are kept: the Linux libc defines __cxa_throw and
__cxa_throw_nid_no_patch_cut as aliases of __cxa_throw_nid_postfix, so
both become __cxa_throw, and any lookup of that name resolves to the
same code.

The Linux libc also exported __gxx_personality_v0 twice at different
addresses: the forwarding function in Personality.cpp and the
__gxx_personality_v0_nid_no_patch_cut alias of the guest personality.
Drop that alias, so the name keeps only the forwarding function, as
in the PE build.

Subject: [PATCH 0399/1000] fix(tools): allow unwrap_self to place zero-size
 segments without a PT_LOAD host

When a decrypted SELF contains a non-PT_LOAD segment (such as PT_TLS for pure TBSS) with p_filesz == 0 whose virtual address lies outside any PT_LOAD memory range, unwrap_self previously refused the container with 'segment N vaddr 0x... is in no PT_LOAD'.

Allow zero-size segments without a matching PT_LOAD host to be placed with source offset 0 and new offset 0, preserving valid ELF headers for titles like Unity/IL2CPP PS5 builds.

Also allow file-empty PT_LOAD segments with stale out-of-file source offsets to skip the segment-extent bounds check, preserving memory sizes, addresses and alignments without reading container metadata.

Because `_sigprocmask` keeps only the first 32 signals, signals 33 to 128 are never blocked and never appear in the set, and setting `SIG_IGN` (or `SIG_DFL` on a signal whose default action is to ignore) does not clear a signal that was already marked pending. PPSA99420 imports it

A null entry crashed the payload and still throws. Joining the calling thread returns `EDEADLK` and a zeroed attribute creates a default thread, as on the console
 - [Thread cancellation](../../../core/libs/prx/libkernel/Pthread/src/Thread.cpp) (libkernel) follows FreeBSD libthr (states and types 0/1 and 0/2, `PTHREAD_CANCELED` 1, the `_pthread_cleanup_info` node layout), not measured on the console. A request is acted on only in `scePthreadTestcancel`, the condition variable, `sem` and `scePthreadSem` waits, `scePthreadJoin` and the sleeps, and their POSIX names; file and socket calls are not cancellation points. A sleep is not interrupted: the thread exits when it ends. The asynchronous type acts like the deferred one, except at the two set calls.

Subject: [PATCH 0401/1000] feat(agc): draw line-strip output of NGG geometry
 programs as mesh lines

A geometry program with VGT_GS_OUT_PRIM_TYPE 1 was refused as an
unsupported output assembly. Each primitive export of an NGG line-strip
program is one line whose indices are packed like a triangle's, so the
mesh module now declares OutputLinesEXT with PrimitiveLineIndicesEXT for
it. A subgroup gets VGT_GS_MAX_VERT_OUT - 1 lines per input primitive and
at least GE_MAX_OUTPUT_PER_SUBGROUP line slots; fast launch keeps using
PRIM_AMP_FACTOR. The output size is part of the cache, draw, validation
and pipeline keys, and the request serialization version becomes 31.
Triangle-strip geometry is unchanged.

 - [Indices far past every vertex fetch](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver) - when a draw's highest index is at least 64Ki vertices past the largest per-vertex record count, every index past that count is moved to it in a copy of the indices, so the zero-padded vertex copies are not sized to the original index (PPSA04159 draws a list of `0xffffffff` with primitive restart off, which asked for 160 GiB). Each attribute fetched by vertex index reads zeros there as at the original index (out-of-bounds select 0 or 1); a draw with another out-of-bounds select keeps its indices. The vertex index the shader sees changes for the moved indices, which a shader that reads it directly would notice
 - [Depth clear draws](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - a draw with `DB_RENDER_CONTROL.DEPTH_CLEAR_ENABLE` is taken to write `DB_DEPTH_CLEAR` to every pixel it covers whatever the depth test, depth bounds and depth bias say: it is drawn with an always-passing depth write and the viewport depth range pinned to the clear value. The draw is rasterized as submitted, so its coverage is the draw's own. Whether the DB still applies the depth test or HiZ to such a draw is not measured
 - [GS_FAST_LAUNCH geometry](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - `VGT_SHADER_STAGES_EN.GS_FAST_LAUNCH = 1` with a point list and `GE_CNTL` groups of one vertex and one primitive decodes as one point per subgroup, with the primitive limit taken from `GE_NGG_SUBGRP_CNTL.PRIM_AMP_FACTOR` and the GS/ES VGPR counts not required. Follows how RADV drives mesh shaders on gfx10.3 (`ac_nir_lower_ngg.c`, the workgroup index comes from the vertex id of the first thread), not measured on the console. Fast launch 2, other group sizes or input primitives and indexed fast-launch draws still throw. PPSA03671's fast-launch draws decode, but the title stops earlier in a wave64 vertex program, so they have not reached the GPU yet.
+- [Line-strip geometry output](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - a geometry program with `VGT_GS_OUT_PRIM_TYPE = 1` (line strip) runs as a mesh shader with `OutputLinesEXT`: each primitive export is one line whose two vertex indices are packed like the three of a triangle, as Mesa's NGG lowering exports line strips (`ac_nir_lower_ngg_gs.c`), and each input primitive gets `VGT_GS_MAX_VERT_OUT - 1` lines where a triangle strip gets `- 2` triangles. A subgroup gets at least `GE_MAX_OUTPUT_PER_SUBGROUP` line slots, because Mesa's lowering exports one primitive, possibly null, per emitted vertex; whether the console's compiler does the same is not known, and triangle strips keep `- 2` per input. A fast-launch subgroup takes its line count from `GE_NGG_SUBGRP_CNTL.PRIM_AMP_FACTOR` as for triangles. Line output counts as lines for the polygon offset decode, as on the vertex path. The lines are drawn 1 pixel wide with Vulkan's default line rasterization, like lines on the vertex path: `PA_SU_LINE_CNTL` is not read, and neither its width nor the console's line rules were measured. Points, rectangle lists, per-stream types and line strips from a vertex program on the mesh path still throw.
 - [Alpha-to-coverage](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - only `DB_ALPHA_TO_MASK = 0xaa01` is accepted: the enable bit with the four quad offsets at 2 and no `OFFSET_ROUND`, the undithered setting [radeonsi](https://gitlab.freedesktop.org/mesa/mesa/-/blob/bffd91947efc1932da99aca69fc540d6d4201b0c/src/gallium/drivers/radeonsi/si_state.c#L371-L381) programs. Draws are single-sampled, so the pixel shader [writes](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) `SampleMask` 0 when its MRT0 alpha is below one half or NaN and all ones otherwise, and runs with late fragment tests. That rule was measured on a Radeon 660M (gfx1035, RADV with `RADV_DEBUG=noatocdithering`, which programs the same register) for 0, -0, 0.25, the two floats below one half, one half, the two above, 0.75, 1, 2, -1, both infinities and both NaNs, and is pinned in [AlphaToCoverage.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/AlphaToCoverage.cpp); it is not measured on gfx1013. Vulkan's `alphaToCoverageEnable` is not used: the NVIDIA driver 615.78.08 dithers single-sample coverage (an alpha of 0.25 writes half the pixels of an RTX 3050 Laptop target). Other offsets, `OFFSET_ROUND`, a sample-mask export, and an MRT0 that is missing, swizzled, packed or exported without a floating-point alpha throw. A draw without a color target on MRT0 keeps alpha-to-coverage from its MRT0 export, as [radeonsi exports MRT0 as `32_AR` for alpha-to-coverage without a color buffer](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-24.0.0/src/gallium/drivers/radeonsi/si_state_shaders.cpp#L2425-L2431). A draw that enables alpha-to-coverage with no MRT0 export still throws: what the console covers then is not measured. Default dithered `DB_ALPHA_TO_MASK = 0x18701` additionally uses a per-quad sample-mask table [measured on gfx1036](https://github.com/boykopovar/AnyPS5/pull/4451#issuecomment-6124848921) for eight standard samples with FP16_ABGR or 32_ABGR exports; other sample counts, custom locations, EQAA combinations and dithered UNORM16/SNORM16 exports throw. The dithered rule is not measured on gfx1013.
 - [MSAA_ENABLE on a single-sample target](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - `PA_SC_MODE_CNTL_0.MSAA_ENABLE` with `PA_SC_AA_CONFIG.MSAA_NUM_SAMPLES = 0` is drawn like the same state without the bit when sample 0 of the four `PA_SC_AA_SAMPLE_LOCS_PIXEL_*_0` registers is at the pixel center and the draw rasterizes filled triangles with alpha-to-coverage and conservative rasterization off. [RADV](https://gitlab.freedesktop.org/mesa/mesa/-/blob/745709a000482a4a24c91faef5c5a40bd653a863/src/amd/vulkan/radv_cmd_buffer.c#L13606-13609) programs this state for one-sample custom sample locations on GFX10 and later, where the bit makes the rasterizer use the programmed location of sample 0 ([061bc615](https://gitlab.freedesktop.org/mesa/mesa/-/commit/061bc6151a11597f720535f00e79a5752e24aff6)); that the bit changes nothing else for such a draw is inferred from that and is not measured on hardware. Other locations of sample 0, absent location registers, points, lines, rectangles, alpha-to-coverage and conservative rasterization throw
 - [sceAgcDriverGetEqContextId](../../../core/libs/prx/libSceAgcDriver/Eq/src/Query.cpp) (libSceAgcDriver) - returns `ident`: an end-of-pipe interrupt is delivered only to the registration whose id equals the raising queue, so `ident` is that context's id (titles register 0 or 1 for graphics and `0x20 + 8 * pipe + queue` for compute). The console's value is not known; KytyPS5 returns the event's `data`, which it fills with the interrupt's context id, whereas `data` here is the EV_CLEAR trigger count. Other event filters throw

Subject: [PATCH 0402/1000] fix(libSceSysmodule): report the region of the
 queried page from a cached unwind region

VirtualQuery describes the pages from the queried address to the end of the run of equal pages, so the reported seg0 begins at the queried page. The cached entry returned the first lookup's page for every later address in the run. It now returns the queried page and the bytes up to the end of the cached run, which is what VirtualQuery returns.

Subject: [PATCH 0403/1000] test(relinker): link the converter tests with a
 small macOS zero page

The CLZERO case that needs a 32-bit address found no mapping because a
64-bit Mach-O executable reserves 4 GiB as `__PAGEZERO`, not because
Rosetta withholds low memory: the same `mmap` succeeds once the
executable is linked with a smaller zero page. The Apple x86-64 build
links the test that way and the case runs with the other three, so the
skip it had is gone and the Linux mapping failure stays fatal. The arm64
build keeps the 4 GiB zero page, which it requires to start.

Subject: [PATCH 0404/1000] Revert "fix(agc): validate mesh index descriptors
 on cached draws" (#5791)

agc_driver_mesh_index_cache aborts on the linux job (lavapipe, LLVM 20.1.2:
"LLVM ERROR: Cannot emit physreg copy instruction") on every main push build
since the merge (first red: 38777177302). The PR was merged on a
windows-only run after a linux-red batch was split.

Subject: [PATCH 0405/1000] test(libSceSysmodule): look up an earlier page of a
 cached unwind region after a later one

The backward lookup added with the region fix compared the address with a page it could not reach and never ran. The test now queries an ntdll address three pages in, then the first page, then the pages between, and compares each with VirtualQuery. The lookups after the first fail on the cache before the region fix.

Subject: [PATCH 0406/1000] fix(libSceSysmodule): test and document unknown
 module ids

sceSysmoduleIsLoaded, sceSysmoduleLoadModule and sceSysmoduleUnloadModule
return success for an id missing from the module table, because titles that
load or unload such an id aborted otherwise (b4db9fdd6, a2520aa07). Nothing
tested or recorded it, and two commented-out throws were left in the code.

Remove the commented-out throws, list the three functions under Silent stubs
in the library's technical debt file, and test that unknown ids succeed
without changing state while the internal variants still throw.

Written with AI assistance (Claude).

+### Silent stubs
+
+- [sceSysmoduleIsLoaded, sceSysmoduleLoadModule, sceSysmoduleUnloadModule](../../../core/libs/prx/libSceSysmodule/Export.cpp) (libSceSysmodule) accept a module id missing from the module table: they log it and return 0 without loading anything, so `sceSysmoduleIsLoaded` reports an unknown module as loaded and unloading it succeeds, because titles that load or unload such an id aborted otherwise. The internal variants (`sceSysmoduleLoadModuleInternal`, `sceSysmoduleUnloadModuleInternal`, `sceSysmoduleLoadModuleInternalWithArg`, `sceSysmoduleGetModuleHandleInternal`) throw for an unknown id. What the console returns for an id it does not know is not verified.

Subject: [PATCH 0407/1000] fix(libSceVideoOut): keep mouse clicks and motion
 off the pad while the title reads the mouse

The default bindings map the left and right mouse buttons to Square and
R2, and mouse mode maps motion to the right stick. A title that opens the
mouse with sceMouseOpen therefore gets every click twice: as a mouse
button and as a pad press. PPSA15388 treats the pad press as a switch to
gamepad input, re-centres its cursor and drops the click, so menu items
cannot be clicked.

While libSceMouse has a handle open, KeyboardMouse ignores mouse motion
and mouse-button presses. Releases still pass, so a button held before
the title opened the mouse is let go. Keys and the wheel are unchanged,
as with the IME guard next to it.

Subject: [PATCH 0408/1000] test(agc): zero the whole pending key store block

agc_pending_key_stores cleared only the first 256 bytes of its 64 KiB block and
then asked for the keys of 512 bytes. The other 256 were whatever the heap
held: when they were not all equal the range read as mixed (correctly) and
the check that it is unknown failed, so the test passed or failed with the
allocator's state (main builds after #5784).

Subject: [PATCH 0409/1000] fix(agc): validate mesh index descriptors on cached
 draws (reapply #5791)

Reapplies #5791 (reverted by #6552). agc_driver_mesh_index_cache now skips
on llvmpipe like agc_driver_mesh does: llvmpipe aborts compiling these mesh
programs (LLVM ERROR: Cannot emit physreg copy), which is what turned main's
linux job red.

Subject: [PATCH 0410/1000] fix(check_compile): take changed units from the
 merge base

changed() diffed the working tree against the tip of the base, so files
changed only on upstream main since the branch point were reported and
compiled. It now diffs against the merge base of the base and HEAD.
A regression test covers a base-only change.

Subject: [PATCH 0411/1000] docs(usage): state that the shader cache directory
 has no size limit

The Shader cache section says only that subdirectories of other versions are removed after 14 days. housekeeping() in ShaderDiskCache.cpp removes nothing from the current version, and no size or entry limit applies there.

Subject: [PATCH 0412/1000] fix(check_main_sync): fetch an explicit --base
 before resolving it

main() resolved the base before running --fetch, so an explicit base on a
remote that was never fetched failed with "no base ref found" and never
fetched. The fetch is now a local helper and runs first when --base is
given; the default base still resolves first, then fetches.

Subject: [PATCH 0413/1000] test(agc): write more pixels than a pipe holds in
 the closed-pipe case

PixelFailure wrote a 128x128 payload, exactly the 64 KiB a default Linux
pipe holds. Once the consumer read the 54-byte header, the whole payload
fit in the pipe, so the write could finish before the reader closed and
the expected EPIPE never came. agc_frame_dump_io failed in 147 of 300 runs
on Linux. A 512x512 payload exceeds the default pipe capacity on Linux and
macOS, so the write always reaches the closed reader.

Subject: [PATCH 0414/1000] test(libc): wait on a _Cnd_timedwait deadline
 beyond the nanosecond range

A deadline of 10^10 seconds does not fit a nanosecond count but fits the
host clock where system_clock counts microseconds, as on macOS. There the
wait must block until it is woken; where the clock cannot hold the
deadline, _Cnd_timedwait must throw the overflow error as for any other
deadline past the clock's range.

Subject: [PATCH 0415/1000] fix(libc): keep the _Cnd_timedwait deadline in the
 host clock's unit

The deadline was built as seconds plus nanoseconds, a nanosecond duration,
and converted implicitly to a system_clock time point. Where system_clock
counts microseconds, as on macOS, that conversion is lossy and does not
compile, so libc did not build there.

The seconds now stay in the clock's unit and only the nanoseconds are
rounded up to it, so the wait never ends before the requested time. With
a nanosecond system_clock nothing changes. Converting the nanosecond sum
instead would compile but overflow above 2^63 nanoseconds, which the
clock range check above allows on macOS: a 10^10 second deadline then
wraps into the past and the wait times out at once.

Subject: [PATCH 0417/1000] test(libc): keep intentional aborts away from the
 system crash handler

guest_host_standard_error and exception_runtime fork children that end in
SIGABRT on purpose. When kernel.core_pattern pipes cores to a handler, as
Ubuntu's apport and systemd-coredump do, the kernel starts it for every
dumpable crash even with RLIMIT_CORE at 0. apport takes about 1.1 s per
crash here, so guest_host_standard_error spent 2.3 s waiting and timed out
at its 10 s limit under parallel ctest load. Marking those children
non-dumpable on Linux skips the handler: 2.29 s to 0.01 s and
1.17 s to 0.01 s, with the same SIGABRT and message checks.

 - [Multisampled color fills](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) (libSceAgcDriver) - a multisampled target's samples are on the host, so a fill of its color memory is applied at its next use: a uniform fill over the whole of it clears the host image to that value, and a pending CMASK fast clear takes precedence over the fill and over a fill that would throw. Its color memory is a single mip and slice of addrlib's block dimensions for its sample count (ComputeThinBlockDimension). A fill over part of it, a fill reaching the start of a target whose footprint is not computed (linear), and a fill value with no exact clear value in the format (sRGB channels other than 0 and 1) throw at the next use. A fill before the target's first use is not seen (the host image starts at 0), nor are copies or shader writes into its color memory. A uniform compute fill over exactly the whole color memory with an exact clear value is not stored into guest memory, since only the host image holds the samples. A target is retired only when its whole guarded range is unmapped or its allocation removed, so if a title reuses that memory for other data while it stays mapped, a read the guard does not check (a buffer read through a V# or a pointer) sees the bytes from before the fill.
 - [Multisampled texture no draw rendered to](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) (libSceAgcDriver) - sampling a multisampled texture whose surface no draw rendered to creates the host target from the T# and clears it to the color a single 32-bit value repeated over the whole footprint encodes, padding up to whole tile blocks included. Inferred, not measured on the console: that the samples of such a surface are the guest color memory, as a title that clears its canvas on the CPU (ps5-opengl `ps5_clear_msaa4_color`) relies on. Memory that is not one repeated value, tile modes other than Standard4KB, Standard64KB and RenderTarget, unmapped memory and values with no exact clear color throw. CPU writes to the surface after its host target exists are not seen by the host.
 - [Multisampled targets in CB passes](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - a CB eliminate or DCC pass over a multisampled target throws, since its texels are on the host and only a CB resolve and an FMASK decompress (`CB_COLOR_CONTROL` mode 5) are modeled. The FMASK decompress only applies the pending CMASK fast clear to the host image; it requires a CMASK address, and the target's DCC and FMASK contents are not interpreted. DCC over a multisampled target is accepted only in that pass and throws everywhere else. A CB resolve into a fast-clear destination throws: the resolve writes the destination's texels but not its CMASK, which would still read as cleared.

 - [CB resolve sample count](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - a draw with CB_COLOR_CONTROL in resolve mode is a CB resolve when either PA_SC_AA_CONFIG or CB_COLOR0_ATTRIB.NUM_SAMPLES is multisampled, and takes its sample count from CB0. Inferred, not from documentation: PPSA36082 resolves its 4x targets with no sample count in PA_SC_AA_CONFIG, and radeonsi sets PA_SC_AA_CONFIG to 0 for a multisampled framebuffer when rasterizer multisampling and line smoothing are off.
 - [Custom MSAA sample locations](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) support a uniform 1x1 pattern for 2, 4 or 8 samples through VK_EXT_sample_locations. Patterns varying across the guest's 2x2 pixel grid use a 2x2 sample location grid, anchored at the framebuffer origin like the guest's while the window offset is zero, on devices whose `maxSampleLocationGridSize` for the sample count is a multiple of 2x2, and throw on others. The RTX 5070 reports 2x4 for 2 samples, 2x2 for 4 and 1x2 for 8; an AMD Radeon integrated GPU reports 2x2 for each. Devices without the required sample count, four subpixel bits or the full guest coordinate range refuse custom patterns. Depth images remain in GENERAL between draws, and render passes cannot continue across pattern changes. Guest offsets retain the existing decoder's signed four-bit, sixteenth-pixel interpretation; PS5 coverage and interpolation equivalence have not been measured on hardware.
 - [DCC display buffers](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) are presented only when all keys of the console's DCC extent agree on uncompressed or a fast-clear code, padding keys included; other keys, and register-clear keys over a pending image, throw.

Subject: [PATCH 0419/1000] feat(libkernel): support EVFILT_READ on the read
 end of a pipe

kevent threw for any descriptor that is not a guest socket. The read end
of a pipe now gets the descriptor knote, following FreeBSD 11's
filt_piperead: data is the number of buffered bytes and EV_EOF is set
once the write end is closed. GuestSockets::Ready falls back to the new
PipeReadState for a descriptor that is not a socket, and WaitAny waits on
the pipe with ppoll on Linux or in 1 ms WSAPoll slices on Windows, only
when the queue holds a pipe. On Windows the equeue waker now starts
Winsock itself, since a queue can wait on a pipe before any socket exists.

 - [sceKernelMprotect, sceKernelMtypeprotect](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) (libkernel) over a range with a gap that is not registered in the allocation tracker protect the registered parts and skip the gap, and return 0, as FreeBSD 11.4's [`vm_map_protect`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/vm/vm_map.c) does (it has no check for holes); a range whose start is unmapped (also when later pages are mapped) returns `SCE_KERNEL_ERROR_EINVAL` (`mprotect`: `EINVAL`) because an existing test pins that for an unmapped start; FreeBSD answers 0 there too (`vm_map_protect` takes the next entry), so this errno is not taken from the source and was not changed. `sceKernelMprotect` threw for a gap before, which ended the title. Every part is checked for a GPU or image pin before the first one is protected; the parts are then protected one after the other, so a host protection failure in a later part leaves the earlier parts changed (FreeBSD's `vm_map_protect` cannot fail in its second pass). The behaviour on the console is not known. None of this was measured on a console.
 - [sceKernelMprotect protection bits](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) (libkernel) - bits outside `0x3F7` are dropped instead of refused, as FreeBSD 11's [`sys_mprotect`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/vm/vm_mmap.c#L606) does with `VM_PROT_ALL`. Onimusha: Way of the Sword (PPSA27836 01.000.001) maps direct memory with `0xf2` and then protects it with `0xfffffff2`. Not measured on a console; the map calls and `sceKernelMtypeprotect` still refuse undefined bits
 - [JIT shared memory](../../../core/libs/prx/libkernel/DirectMemory/Jit.cpp) (libkernel) - `sceKernelJitCreateSharedMemory`, `sceKernelJitCreateAliasOfSharedMemory` and `sceKernelJitMapSharedMemory` take the signatures of [Orbital](https://github.com/AlexAltea/orbital)'s `tools/ida/db_types.json` (name, length, maximum protection, descriptor out; descriptor, maximum protection, descriptor out; descriptor, protection, address in and out), which ps4sdk, ps5-jar-loader and the call sites in RetroArch PPSA99169, XPSemu PPSA97358 and VLC PPSA85300 match; SharpProspero declares the alias as returning the descriptor. The object is a host anonymous file shared by its descriptors (a `memfd` on Linux, a delete-on-close temporary file mapped as an executable section on Windows), the alias is a duplicate descriptor, and every map maps the whole object, so writes through one view show through the others; a non-null address is a hint, as in `mmap` without `MAP_FIXED`. Not measured on the console: a length that is zero or not a multiple of 16 KiB and protection bits other than CPU read, write and execute are `EINVAL`; an alias or a map asking for more than the descriptor's maximum protection (write and execute counting as read) is `EACCES`, as FreeBSD 11's `vm_map_protect` treats a protection past `max_protection`; a descriptor that is not a JIT object is `EBADF`. The name is ignored, the objects do not count against the flexible memory budget, `mprotect` of a view is not limited to the maximum protection, and `mmap` of the descriptors is unsupported, as for `shm_open`. On Linux the `memfd` is created without `MFD_EXEC`, which Linux 6.3 added and older kernels reject with `EINVAL`, and relies on the protection of the mapping: the flag only sets the file's execute permission bits, and the direct memory `memfd` is mapped executable the same way; a host with `vm.memfd_noexec` set to 2 refuses the creation and the call throws

A new user event keeps its `fflags` unmasked and is not triggered by `NOTE_TRIGGER`, because `filt_userattach` reads the already cleared `kn_fflags`. The timer limit `kq_calloutmax` (`ENOMEM`) is not enforced, and closing a kqueue wakes a thread waiting on it in `kevent` with `EBADF`, where `kqueue_drain` makes the close wait for that thread.

 - [EVFILT_VNODE, sceKernelAddFileEvent and sceKernelDeleteFileEvent](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) (libkernel) watch the host file or directory behind the descriptor and turn host changes into FreeBSD 11 vnode hints, which [`filt_vfsvnode`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L5032) adds whole when they share a bit with the requested `fflags`: a write that grows a file is `NOTE_WRITE | NOTE_EXTEND`, another write `NOTE_WRITE`, a shrinking truncate or an attribute change `NOTE_ATTRIB`, a higher link count `NOTE_LINK`, a lower one or a pending delete `NOTE_DELETE`, a new path `NOTE_RENAME`; in a directory, an entry created, removed or renamed is `NOTE_WRITE`, with `NOTE_LINK` for a subdirectory, and on Linux an entry moved from or to another directory adds `NOTE_EXTEND`; inotify queues the two halves of a rename one after the other, so a watcher woken by the first can read it alone, and a half read without the other is classified only after a `getdents64` on the watched directory, which takes the directory lock that `rename` holds until both halves are queued ([`do_renameat2`](https://github.com/torvalds/linux/blob/v6.8/fs/namei.c#L4975) around `vfs_rename` and its `fsnotify_move`, [`iterate_dir`](https://github.com/torvalds/linux/blob/v6.8/fs/readdir.c#L103)), an ordering taken from the kernel source, not from inotify(7), which promises none; a directory registered with `NOTE_EXTEND` on Windows is accepted, as `vfs_kqfilter` does not check it, but never receives it, because the directory handle cannot tell a move between directories from a removal plus an addition. FreeBSD's hints depend on the filesystem and the console's filesystems are not known: a growing `ftruncate` reports `NOTE_WRITE | NOTE_EXTEND` where `vop_setattr_post` reports `NOTE_ATTRIB`, and on Windows `utimes` on a file reports `NOTE_WRITE`. The three Windows notifications are told apart in the error, which names the `parent`, `entries` or `subdirectories` watch, the path it was given and `GetLastError`, but a `FindFirstChangeNotification` that fails still throws rather than returning an error to the guest: the EVFILT_VNODE attach path is [`vfs_kqfilter`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L4936), which returns `EINVAL`, `ENOMEM` or 0 after `fget` has turned a descriptor that is not open into `EBADF`, and consults no directory permission, so no FreeBSD errno stands for a host that refuses to notify, and what the console does on such a host is not measured. Only the `parent` watch can fail this way in practice: `entries` and `subdirectories` need the `FILE_LIST_DIRECTORY` that opening the watched directory already took. The parent handle produces no hint of its own, as `RunHostWatch` only calls `FindNextChangeNotification` on it, so a later change may leave the watch on its 50 ms poll instead of throwing; that is not done here. Windows uses `FindFirstChangeNotification` on the parent directory (and on a watched directory itself) and compares `GetFileInformationByHandleEx` snapshots at least every 50 ms, because a write through an open handle is reported only when the handle is flushed or closed, so file hints can arrive 50 ms late, and a file deleted while watched, which the POSIX delete of Windows 10 1903 moves into `$Extend\$Deleted` until its last handle closes, reports `NOTE_DELETE` without `NOTE_RENAME` and keeps its handle without a parent directory watch, as that directory cannot be watched; Linux uses inotify on the file and is not run. `NOTE_REVOKE`, `NOTE_OPEN`, `NOTE_CLOSE`, `NOTE_CLOSE_WRITE`, `NOTE_READ`, unknown bits and descriptors other than files, directories, pipes and sockets throw. `sceKernelAddFileEvent(eq, fd, watch, udata)` and `sceKernelDeleteFileEvent(eq, fd)` take the [OpenOrbis](https://github.com/OpenOrbis/OpenOrbis-PS4-Toolchain/blob/0a1aaf9d/include/orbis/libkernel.h#L35) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0/src/SharpProspero/Interop/Kernel/KernelEqueue.cs#L164) signatures; `watch` is taken as the `fflags` and the event is added with `EV_CLEAR`, neither confirmed on a title (feat(libkernel): implement kevent EV_DISABLE, EV_DISPATCH and EV_FORCEONESHOT) (fix(libkernel): follow kqueue_register for EV_FORCEONESHOT and modify flags)
 - [sem_timedwait](../../../core/libs/prx/libkernel/Pthread/Posix/Sem.cpp) (libkernel) consumes an available count before checking the timeout and waits indefinitely for a null timeout, following FreeBSD 11's `sem_timedwait`. Console behavior for null and invalid timeouts when a count is available is unverified.
 - [tcsendbreak, tcdrain, tcflush, tcflow, tcgetpgrp, tcsetpgrp](../../../core/libs/prx/libkernel/File/src/Terminal.cpp) (libkernel) follow FreeBSD 11.4's [`termios.c`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/gen/termios.c): `tcflush` answers `EINVAL` for a queue other than `TCIFLUSH`, `TCOFLUSH` or `TCIOFLUSH` and `tcflow` for an action outside `TCOOFF`..`TCION` before the descriptor is looked at, and every other call fails as its terminal ioctl does on a descriptor that is not a terminal, with the errors `tcgetattr` gives, so `tcsendbreak` never reaches its 0.4 s pause. FreeBSD's `pipe_ioctl` answers `TIOCGPGRP` and `TIOCSPGRP` on a pipe or FIFO with the descriptor's SIGIO owner, which is not modelled, so `tcgetpgrp` and `tcsetpgrp` throw on a host pipe or FIFO above descriptor 2; descriptors 0 to 2 are taken as non-terminals that are not pipes, whatever the host attaches to them, so a pipe the guest creates on a freed descriptor 0 to 2 gets `ENOTTY` there. The PS5 `libkernel` is assumed to use this FreeBSD code, and `tcdrain` is not a cancellation point here

 - [Socket descriptor numbers](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel, libSceNet) - `socket`, `accept`, `socketpair`, `dup`, `sceNetSocket` and `sceNetAccept` take the lowest free number of the host descriptor table that files use, as FreeBSD 11.4 `fdalloc` takes the lowest free entry of the one process table (`kern_descrip.c`), so every number stays below `FD_SETSIZE` (1024) while fewer than 1024 descriptors are open. The number holds a zero-access `NUL` handle on Windows and a duplicate of the host socket on Linux, and the socket tables map it to the socket. The host table also holds the runtime's own files, so the numbers differ from the console's; the first number `socket` and `sceNetSocket` return on a console and its `getdtablesize` are not measured. Paths that bypass the socket tables see the placeholder: libc `fdopen` on a socket opens it, and libkernel `close` of a libSceNet socket releases the number but leaves the libSceNet socket open. Palworld (PPSA23126), The Mound (PPSA26223) and Dying Light 2 (PPSA02262) set socket bits in a 1024-bit `fd_set`
 - [fstat on a guest socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) fills the fields FreeBSD 11's soo_stat and pru_sense_null fill and zeroes the rest: S_IFSOCK, the read bits while the receive side is open or data is queued, the write bits while the send side is open, st_size and st_blksize. Only this process's shutdown closes a side here; a peer's shutdown, close or reset does not clear the bits as FreeBSD's socantrcvmore and socantsendmore do. st_size is the host's FIONREAD, which for a Linux datagram socket is the size of the next datagram where FreeBSD counts every queued byte, and st_blksize is the host's SO_SNDBUF, which Linux reports as twice the size that was set. A socketpair end reports st_dev and st_ino 0, where FreeBSD's uipc_sense reports NODEV and a per-socket number
 - [poll](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) waits on guest sockets and pipes, through `WSAPoll` on Windows and `poll` on Linux; the `pollfd` layout and flag values are FreeBSD's. A libSceNet socket joins the same host wait through the native socket libSceNet lends to libkernel. `WSAPoll` rejects `POLLPRI`, so on Windows a socket's `POLLPRI` is asked as `POLLRDBAND` and `POLLIN` as `POLLRDNORM`; Winsock reports urgent data until it is read with `MSG_OOB`, where FreeBSD 11.4's `sopoll_generic` stops once the normal stream passes the mark. Guest `send` and `recv` refuse `MSG_OOB` with `EOPNOTSUPP`, so urgent data can only come from an outside peer and Windows keeps reporting `POLLPRI` after the stream passes the mark. A pipe follows FreeBSD's `pipe_poll`: the read end is readable when data is buffered, either end reports `POLLHUP` once the other end is closed, with the requested `POLLIN` and `POLLRDNORM` bits and without `POLLOUT`, which `pollscan` clears, and the write end is writable when `PIPE_BUF` (512) bytes are free on Windows, or when the host kernel says so on Linux. `POLLOUT` on a read end throws: FreeBSD opens both ends for reading and writing and reports it writable, and host pipes are one-way. Windows pipes cannot be waited on, so while a pipe is polled `poll` checks it with `NtQueryInformationFile` and waits on the sockets in slices of 1 ms. A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket nor a pipe (files, stdio) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on. A closed socket descriptor reports `POLLNVAL`; the console's limit on the descriptor count is unknown and not checked
+- [kevent on a pipe](../../../core/libs/prx/libkernel/Equeue/src/Kqueue.cpp) (libkernel) - `EVFILT_READ` on the read end of a pipe follows FreeBSD 11's [`filt_piperead`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/sys_pipe.c#L1787-L1806): `data` is the number of buffered bytes, and `EV_EOF` is set once the write end is closed. Windows pipes cannot be waited on, so while a kqueue waits on a pipe it checks it with `NtQueryInformationFile` and waits on its sockets in slices of 1 ms; a wait with no pipe is not sliced. `EVFILT_READ` on the write end of a pipe throws: FreeBSD's `pipe` opens both ends for reading and writing ([`kern_pipe`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/sys_pipe.c#L422)), and host pipes are one-way. `EVFILT_WRITE` on a pipe and `NOTE_LOWAT` on a pipe, which `filt_piperead` ignores, throw too.
 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
 - [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.
 - [connect to AF_UNSPEC](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) dissolves a datagram association as FreeBSD 11.4's `udp_disconnect()` does, which resets the local address to the wildcard address and keeps the port. On Linux a socket bound to an explicit port keeps its local address as well (`127.0.0.1:<port>` stays `127.0.0.1:<port>`), because a bound socket cannot be bound again; one bound to port 0 is bound again to the wildcard address with the port it had

Subject: [PATCH 0420/1000] fix(agc): close only the shader preparation pools
 that exist at shutdown

CloseRegistrationPreparation took RegistrationPreparePool::Instance(),
which creates the pool and starts its detached workers (half the
hardware threads, at least two) when nothing was queued for preparation
yet. In a process that prepared nothing in the background, the driver's
shutdown started the workers only to close the pool, and the process
exited while they were still starting. Their first waits take the
global lock of winpthreads' statically initialized condition variables;
ExitProcess killed them holding it, and the destructor of the next
static condition variable that was never waited on spun on it forever
at DLL detach (~DeviceUseGate in ~Driver, or one of libkernel's). On
GitHub's Windows runners agc_interpolant_mapping hung that way in 15 of
60 rounds of eight test runs.

Shutdown now closes only the pools that exist, and a pool first used
after it starts no workers, so later preparations run on the caller as

Subject: [PATCH 0421/1000] fix(agc): join the shader preparation workers when
 their pool closes

Closing a preparation pool waited until its queue was empty, but its
detached workers stayed parked on the queue until ExitProcess killed
them. A pool first used shortly before shutdown still had workers
starting at exit, inside the first waits that take winpthreads' global
condition-variable lock, which the next DLL-detach destructor of an
unwaited static condition variable then waits for forever.

The workers are now joinable and leave once their pool is closed and
idle, and Close joins them, so after the driver's shutdown no
preparation worker is running or starting.

Subject: [PATCH 0422/1000] fix(agc): stop and join the compare helpers and the
 pipeline library worker at shutdown

Two more detached driver threads were never stopped: the helpers of the
parallel compare pool, started at the first large compare, and the
pipeline library's job thread, started at the first link-time optimized
pipeline. A process that exited right after starting them killed them
inside the first waits that take winpthreads' global condition-variable
lock, as with the preparation workers.

The driver's shutdown now stops both and joins them, after the device
is reset. A compare in progress finishes first and later compares run
on the caller. The library worker finishes the job it is running, the
jobs still queued are dropped and counted off their device, and later
pipelines are not optimized in the background.

Subject: [PATCH 0423/1000] test(libkernel): drop backup privileges in denied
 parent watch

An elevated Windows process can bypass the parent directory DACL while holding SeBackupPrivilege or SeRestorePrivilege. Remove both privileges before DeniedParentWatch so the test exercises the denied-open path reliably.

Subject: [PATCH 0426/1000] fix(tools): find Python and CMake comments across
 multi-line strings

The comment check looked at each added .py, .cmake and CMakeLists.txt
line on its own and treated any # outside a string closed on that line
as a comment. A # inside a Python triple-quoted string or a CMake
quoted or bracket argument that spans lines was reported, so adding an
#include to the C++ held in PatchSpirvTools.cmake's [=[ ]=] arguments
failed the check. An escaped \# in CMake was reported too, while the
inner lines of a multi-line #[[ ]] bracket comment were not.

Find comments over the whole file instead: Python COMMENT tokens from
tokenize, and a CMake scan that skips quoted and bracket arguments and
escapes and covers every line of a bracket comment. A Python file that
does not tokenize keeps the previous per-line check.

Subject: [PATCH 0427/1000] fix(tools): read workflow job keys at the
 indentation the file uses

The ci-gate check read a job's needs and if only two spaces deeper
than the job name. In a workflow indented by four spaces those keys
were never found, so a job gated with needs: eligibility and an if on
its outputs was reported as ungated. Read the keys at the indentation
of the job's first child instead.

Subject: [PATCH 0428/1000] fix(tools): fail when the trace_digest --summary
 file does not exist

load_summary returned None for a missing file whether the path was the
default aps5-summary.jsonl next to the trace or one named with
--summary. A mistyped --summary path was therefore silently ignored:
the digest printed "no summary line found" and, without the window end,
dropped the last frame of the window. Report an explicitly named file
that does not exist as a usage error; the default stays optional.

outlive the device, because ClearPipelineLibraries waits for the
device's jobs to finish, but that was only visible inside the wait.

The worker now stops first: a running job finishes, queued jobs are
dropped, and no job runs once the device's teardown starts.
agc_driver_draw_cache_reuse checks that the driver's own shutdown
leaves no library worker running.

Subject: [PATCH 0431/1000] feat(agc): return whole 64 KiB blocks to the
 Windows write watch

GuestMemory::Rewatch takes ranges that left the write watch back into
it. Only whole tracker blocks whose pages can be collected return:
their write-watch marks are collected and dropped, and every block is
stamped as a CPU store with a new generation, so a snapshot or a proof
made before the block left the watch reads as changed, and the blocks'
untracked hints stop applying. It does nothing outside Windows.

Subject: [PATCH 0432/1000] perf(agc): settle Windows imports under 1 MiB
 without waiting

Since #6060 a Windows host import of private write-watched memory stays
in the write watch only after its settle, a 4-byte GPU read that the
importing thread waits for, and only imports of 1 MiB or more are
settled: SuperTuxKart imports a 64 KiB buffer around every submission,
and the wait cost it about 19% of its frame rate. A smaller import is
compared instead, and its range leaves the write watch for good.
Resident Evil Village maps its GPU heap in 64 KiB pieces, so every
texture over that heap is compared with guest memory.

An import under 1 MiB is still compared when it is made, but its read is
now queued. The next import lookup that holds the device lock records
the reads queued since into one batch on the settle queue and submits
it, so the thread that maps and imports neither submits nor waits.
Once the batch's fence has signalled, a later lookup returns the
imports' blocks to the write watch, except where storage results are
pending over them, which waits for a later lookup. An import retired
while its read is in flight waits for that batch first.

A settled import whose range had already left the write watch, such as
a whole range imported over a piece that was compared, returns to it
the same way.

Subject: [PATCH 0433/1000] docs(agc): describe the settle of Windows imports
 under 1 MiB

ARCHITECTURE.md and the debt entry describe how imports under 1 MiB are
settled without waiting and return to the write watch, which the debt
entry listed as not implemented.

 - A draw whose `PA_SC_AA_CONFIG` selects 2, 4 or 8 samples renders into host-only multisampled images. [`MultisampleTarget.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) keeps one image per device, surface address, format, extent and sample count (`MultisampleTargetView`); the pipeline, render pass and library keys carry `State::samples`, and a multisampled depth target is a multisampled depth surface. The guest sample planes and FMASK are never read or written, so the registry also guards the target's guest range: a CPU read (`GuestMemory::SetReadGuard`), a DMA copy, and a sampled or storage image read of it throw. A `CB_COLOR_CONTROL` resolve mode over a multisampled CB0 runs as a render pass whose resolve attachment is CB1's resident image (`ResolveMultisampleTarget`). A zero fill of the target's CMASK (`NoteColorMetadataFill`, from fill kernels and CP DMA fills) clears the image at its next use.
 - A texture over a depth surface samples the depth image itself when it views one 2D slice of the plane's own format (`DepthSurfaceTexture` in [`DepthSurface.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp)). A view of several slices (a 2D array or a cube) or an integer view of a D16 plane is served by a `DepthPlaneCopy`, an image the slices are copied into at every use: from the depth surface bound at each slice's address, else from guest memory. Such a texture is never kept in the resource templates (`RefreshedPerUse`).
 - Guest memory reaches the GPU through host imports (`VK_EXT_external_memory_host`) where the driver accepts them, and through copies otherwise ([`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp)). A registered range larger than the import window (64 MiB) is imported per window for buffer and fill accesses and whole for an address-based build. Live imports stay under a budget, with the least recently used import retired first (see TechnicalDebt, Host import windows and budget).
-- On Windows, a host import of private `MEM_WRITE_WATCH` memory (singly mapped direct memory) stays on `GetWriteWatch` when `ProbeImportWriteProtection` shows the driver reports nothing written after the second GPU read and a GPU write, and a CPU store is collected (`decideImportWatch`). The driver marks every page of such an import written, asynchronously, until its first GPU use completes, so `settleImport` in [`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) copies 4 bytes out of the new import on a second queue of the graphics family, or on a queue of another copy-capable family when the graphics family has only one (`Context::settleQueue`, own pool and mutex) inside `ImportWatched`'s window and waits for it, only for imports of 1 MiB or more (a smaller import is compared, so a title that maps, imports and unmaps a small buffer around every submission does not block its mapping thread); the main queue can't be used there because `importAllocation` holds the imports lock and `GpuMutex` comes before it in the lock order. Imports through a section alias keep tracking on the guest views, and every other Windows host import is compared. A device without such a queue keeps the comparisons.

A smaller import is compared when it is made, so a title that maps, imports and unmaps a small buffer around every submission does not block its mapping thread. Its 4-byte read is queued instead: the next import lookup that holds `GpuMutex` while the imports match the registry (`settleUnwatchedImports`) records the queued reads into one batch on the settle queue, and once the batch's fence has signalled a later lookup returns the import's whole 64 KiB blocks to the write watch (`GuestMemory::Rewatch` drops their marks and stamps every block as a CPU store), except while storage results are pending over them. A settled import whose range had already left the watch returns the same way, and an import retired while its read is in flight waits for that batch. Imports through a section alias keep tracking on the guest views, and every other Windows host import is compared. A device without such a queue keeps the comparisons.

 - [Draw input snapshots](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver): `PrepareDrawBindings` caps read-only input buffer snapshots at 64 MiB (overridable via `APS5_DRAW_SNAPSHOT_MAX_MIB`). Larger inputs (streaming heaps, bindless pools) or draws exceeding the cumulative budget skip the per-draw snapshot and bind in place, avoiding multi-gigabyte CPU copy stalls (such as Ratchet & Clank: Rift Apart PPSA01474 stalling at frame ~380 copying 36 GB every 5 s). If the title rewrites those large ranges on the CPU before GPU completion, the in-place binding observes the modification, as verified by `drawSnapshotCapTests`.
 - [Pending storage-image results](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) are stored when something reads their memory, not when the GPU work that wrote them completes. A title that waits for that work, frees the image and reuses its memory can have the new data overwritten by the late store (#1970). A title's own CPU reads are not seen either, so a title that reads the results after waiting for a label reads stale memory. `APS5_STORE_AT_FLIP=1` stores every pending result at each flip and `APS5_STORE_AT_LABEL=1` before each label the GPU writes; both store every pending image, not only the ones the waited-for work wrote, and neither is on by default.
 - [Pending storage-image results over memory outside the write watch](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) leave to the CPU the 64 KiB blocks whose bytes differ from the ones saved at the upload, the fill, the image copy, the previous store or the moment their range left the watch (`Unwatch`, or a host import that does not stay watched), and the blocks the watch saw the CPU write before that moment. A store made on the GPU saves its bytes through a host-visible copy that becomes the saved bytes when its batch completes; a store or a refresh that needs them earlier waits for that batch. A unit without a write generation saves the guest bytes when results land in it outside the watch. One whose range leaves the watch while its results are pending, and ranges that leave the watch through a failed collect, have no saved bytes; storing such results throws.
-- Windows host-pointer imports of the guest mapping itself are compared instead of write-watched, except writable imports of private `MEM_WRITE_WATCH` memory of 1 MiB or more when the import probe keeps the write watch and a settle queue exists (see Pages under an import window): a driver can mark imported pages dirty after the synchronous import window. Shared memory imported through a separate writable alias retains protection-based tracking on the guest views; driver access to the import alias does not disarm those views. [GuestMemory](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) excludes every overlapping 64 KiB tracker block while its backing is retained. A full block replaced by fresh private backing regains tracking and gets a new generation; protection changes, partial replacements and shared remappings do not restore it. Excluded blocks keep their write-watch marks as a hint only (`UntrackedHint`): a storage image or a sampled texture snapshot over them compares its bytes again after a mark in its range, a driver store, a mapping change or a recorded GPU write instead of at every collect epoch or lookup, and a mark the driver makes without a CPU store costs one comparison. This preserves CPU edits through byte comparisons but limits snapshot reuse on excluded blocks to draws of one collect epoch and disables unit shadows for them; restoring tracking on import retirement without replacing the backing remains unimplemented.
-- [Pages under an import window](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) (libSceAgcDriver) whose write protection was resolved while a host import that leaves its range watched was made are compared with the bytes they held before the import and count as stored over only when those differ. A CPU store of the bytes already there within the window cannot be told apart from an import that resolves the write protection without storing, as the NVIDIA driver (610.57.04) does for every imported page, so such a store does not win over pending results. Where host-pointer and dma-buf imports differ in whether they stay watched, a failed host-pointer import and the dma-buf import after it are two windows, and the pages the failed one resolved count as stored over. On Windows, the NVIDIA driver (617.42) marks every page of a host import of private `MEM_WRITE_WATCH` memory written, asynchronously, until the import's first GPU use completes. Such an import stays watched only after a 4-byte read of it on the settle queue has completed inside the window. Each one waits for that read, which keeps its window open for one round trip on the settle queue, so a same-value CPU store from another thread in that time counts as unchanged too. An import made where no settle queue exists, and an import of under 1 MiB, is compared instead: the settle blocks the importing thread, and a title that imports a 64 KiB buffer around every submission lost about 19 % of its frame rate to that wait (Dripl1x, #6060).

It is compared until its read, submitted in a batch by a later import lookup under `GpuMutex` while the imports match the registry, has completed; a later lookup then returns its whole blocks to the write watch, each stamped as a CPU store, so whatever was derived from them while they were compared reads as changed once. Its blocks stay compared while storage results are pending over them, and those of an import retired before that stay compared.
 - [Sparse dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a shared-backed range larger than one 64 MiB udmabuf buffer is imported as one sparse buffer bound to the 64 MiB buffers, on a queue of its own when the device has a second family that binds sparse memory. The path is decided before anything is imported, and a failure after that throws. A range takes the single udmabuf import instead, which udmabuf's `size_limit_mb` refuses above 64 MiB by default so the range is copied, when its offset in the backing file is not a multiple of the buffer's sparse block size (64 KiB on RADV), when the sparse buffer does not accept every memory type a chunk import can have, when the backing file ends inside its last chunk, or when it is imported at map time on a device with no second family (the bind then needs the GPU mutex); the NVIDIA proprietary driver imports no dma-buf memory
 - [Unnormalized S# coordinates](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) - `FORCE_UNNORMALIZED` uses a Vulkan `unnormalizedCoordinates` sampler, so the S# LOD range, LOD bias and mip filter are not applied, which is exact only on a one-level view.
 - An [unnormalized S#](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) maps clamp mode 0 (repeat) on X and Y to clamp-to-edge as required by Vulkan unnormalized coordinates, and assigns the magnification filter when minification and magnification filters differ (since unnormalized coordinates sample at LOD 0). Anisotropy, TRUNC_COORD, MC_COORD_TRUNC and other clamp modes still throw. Secondary LOD bias (LOD_BIAS_SEC, bits [19:14]) is accepted and ignored, matching RDNA2 hardware measurements across explicit and implicit samples. High on Life (PPSA15388, #4736) uses secondary LOD bias and unnormalized coordinates with clamp mode 0 and differing min/mag filters during home base and city rendering.

Subject: [PATCH 0434/1000] fix(agc): stop and join the draw pipeline's
 committer at shutdown

The committer of pipelined draws, started at the first pipelined
submission, was never stopped. The driver's shutdown joined the queue
workers and left the committer parked on its queue, and a commit the
last submission left queued, such as its deferred completion, could
still run after the shutdown had reset the device. A process that
exited right after its first pipelined submissions could kill the
committer inside its first wait on the queue, which takes winpthreads'
global condition-variable lock, as with the preparation workers.

The driver's shutdown now stops the committer after joining the queue
workers and before taking the GPU lock. The committer runs the commits
still queued and leaves, and the shutdown joins it. A commit enqueued
after that runs on the caller.

Subject: [PATCH 0435/1000] fix(agc): stop and join the shader disk cache
 writer at shutdown

The shader disk cache's writer, started with the cache at the first
shader lookup, was detached and never stopped. It stayed parked in a
timed wait on its queue until the process exit killed it, and entries
still queued at exit were never written. A process that exited right
after its first shaders could kill the writer inside its first wait,
which takes winpthreads' global condition-variable lock, as with the
driver's own threads.

The writer is now joinable. The driver's shutdown stops it after the
other driver threads: the writer writes the entries still queued and
leaves, and the shutdown joins it. A store after that is written on the
caller, and a cache first used after the shutdown starts no writer.
ShaderDiskCache::Shutdown joins the names the cache key check has
reviewed, since it changes nothing a recompile produces.

 - [realpath](../../../core/libs/prx/libc/src/RealPath.cpp) (libc) follows FreeBSD 11's [`realpath.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libc/stdlib/realpath.c) except for symlinks. The console's guest filesystem has none, so a host symlink under the guest root is followed for existence and type but not expanded, and `..` drops the previous component lexically, as `Resolve` does for every guest path. Through a host link `linkdir -> sub/deep`, `linkdir/../x` gives `x` beside the link, not beside its target.
 - [strtod, strtof, strtold](../../../core/libs/prx/libc/src/Strings.cpp) (libc) - `NAN(n-char-sequence)` converts to the quiet NaN that `nan` and `nanf` return, negated after a minus sign, and ignores the sequence as they ignore their tag. This is inferred from C17 7.12.11.2p2, which makes `nan("n")` equivalent to `strtod("NAN(n)", NULL)`, and not observed on the console. No console `nanl` was observed, so `strtold` returns the x87 default quiet NaN (exponent `0x7fff`, significand `0xc000000000000000`)
 - [nan and nanf](../../../core/libs/prx/libc/src/Math.cpp) (libc) return fixed quiet NaN values (`0x7fc00000` and `0x7ff8000000000000`), ignoring the tag argument as observed in the console's `libc.prx` (both exports load a global constant via `mov rax,[rip+..]; vmovsd xmm0,[rax]; ret`); VLC (PPSA85300) stops on nanf at start-up after strsep.
-- [lgamma](../../../core/libs/prx/libc/src/Math.cpp) (libc) returns the host's `lgamma` but does not store the sign of Γ(x) in the guest's `signgam`, as FreeBSD 11's [`e_lgamma.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/msun/src/e_lgamma.c) does through `__ieee754_lgamma_r`, because no guest `signgam` is exported. PPSA99004 imports it. Console behaviour is unverified
+- [lgamma and signgam](../../../core/libs/prx/libc/src/Math.cpp) (libc) - `lgamma` returns the host's `lgamma` and stores the sign of Γ(x) in the exported `signgam` (NID `5gOOC0kzW0c`, starting at 0 as in FreeBSD 11's [`s_signgam.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/msun/src/s_signgam.c)) by the rules of [`e_lgamma_r.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/msun/src/e_lgamma_r.c): -1 for -0 and for a negative non-integer whose floor is odd, 1 otherwise, including poles, infinities and NaN. Taken from the FreeBSD source, not measured on the console. The NID is in the aerolib symbol list; no title is known to read `signgam`. PPSA99004 imports `lgamma`
 - [sinhf](../../../core/libs/prx/libc/src/Math.cpp) (libc) follows the `sinhf` of the `libc.prx` bundled with PPSA28319 (disassembly): FreeBSD msun's [`e_sinhf.c`](https://github.com/freebsd/freebsd-src/blob/5aa554c7e5b6fd9042986df07f12ac5687e41392/lib/msun/src/e_sinhf.c) from before `__ldexp_expf`, which squares `expf(|x| / 2)` between `logf(FLT_MAX)` and the overflow threshold, calling msun's [`expm1f`](https://github.com/freebsd/freebsd-src/blob/59bc2f095289a10b8cfa55cbb2b45c3bd6c2d4ae/lib/msun/src/s_expm1f.c) and [`expf`](https://github.com/freebsd/freebsd-src/blob/59bc2f095289a10b8cfa55cbb2b45c3bd6c2d4ae/lib/msun/src/e_expf.c), whose paths for the arguments it passes are inlined here. Past the threshold Sony's error helper sets `errno` to `ERANGE` before returning `x * 1e37`; msun itself sets no `errno`. That code, run on a Windows host, gives the same bits as this implementation for every finite argument up to the threshold, of both signs; it was not run on Linux. That the system `libSceLibcInternal`, which Ruffle (PPSA68091) and RetroArch (PPSA99169) import while bundling a zero-return `libc.prx`, has the same code is assumed
 - [asinl](../../../core/libs/prx/libc/src/Math.cpp) (libc) follows the `asinl` of the `libc.prx` bundled with PPSA28319 (disassembly), FreeBSD msun's [`e_asinl.c`](https://github.com/freebsd/freebsd-src/blob/9f0432041b8fb69832f10c32da50a67f34feeb61/lib/msun/src/e_asinl.c) with the ld80 [`invtrig.c`](https://github.com/freebsd/freebsd-src/blob/9f0432041b8fb69832f10c32da50a67f34feeb61/lib/msun/ld80/invtrig.c) coefficients, which the binary holds as the same 80-bit constants. For |x| > 1, the infinities and NaN, Sony's error helper raises `FE_INVALID` and sets `errno` to `EDOM` before returning `(x - x) / (x - x)`, so a NaN argument also sets `EDOM`; msun itself sets no `errno`. 20 million random arguments in (-1, 1) give the same bits as that code run on a Windows host. The result needs the x87 precision control at 64 bits, as FreeBSD amd64 starts threads (control word `0x37f`), but guest threads do not set it: on Windows a thread started by `_beginthreadex` runs at 53 bits (`0x27f`), where `asinl(0.75)` returns mantissa `0xd91a98ae3406e000` instead of `0xd91a98ae3406e041`. The system `libSceLibcInternal` that RetroArch (PPSA99169) imports is assumed to have the same code
 - [atanhf](../../../core/libs/prx/libc/src/Math.cpp) (libc) follows the `atanhf` of the `libc.prx` bundled with PPSA28319 (disassembly): FreeBSD msun's [`e_atanhf.c`](https://github.com/freebsd/freebsd-src/blob/59bc2f095289a10b8cfa55cbb2b45c3bd6c2d4ae/lib/msun/src/e_atanhf.c) calling msun's [`log1pf`](https://github.com/freebsd/freebsd-src/blob/59bc2f095289a10b8cfa55cbb2b45c3bd6c2d4ae/lib/msun/src/s_log1pf.c), whose paths for the positive arguments it passes are inlined here; the exported `log1pf` is still the host's. For |x| > 1, the infinities and NaN, Sony's error helper raises `FE_INVALID` and sets `errno` to `EDOM` before returning `(x - x) / (x - x)`, and for |x| = 1 it raises `FE_DIVBYZERO` and sets `errno` to `ERANGE` before returning `x / 0`; msun itself sets no `errno`. That code, run on a Windows host, gives the same bits, `errno` and floating-point exceptions as this implementation for all 2^32 arguments; it was not run on Linux. That the system `libSceLibcInternal`, which Dusklight (PPSA99305) imports while bundling a zero-return `libc.prx`, has the same code is assumed

Subject: [PATCH 0440/1000] docs(debt): list the unimplemented AJM codec 23 of
 PPSA21480

Broken Sword - Shadow of the Templars: Reforged stops at AJM decoding codec 23, which is not one of the codec ids known in Ajm.cpp (MP3 0, ATRAC9 1, M4AAC 2, Opus 24).

The gapless sideband reports the total and skip counts the title set and does not count them down: RPCSX does the same, shadPS4 counts them down and BryKytyPS5 returns its current counts
 - [AJM Opus decoder](../../../core/libs/prx/libSceAjm.native/src/Ajm.cpp) (libSceAjm.native, codec 24) - the initialize parameter layout and little-endian `u16` packet byte count come from The Smurfs Dreams (`2, 48000, 0`) and Lost Soul Aside (`4, 48000, 1`). The third word is interpreted as the mapping family, as in [KytyPS5's initialize structure](https://github.com/KytyPS5/KytyPS5/blob/984cfcebd141b211aa9e0a8cde63b0ebe652d07a/src/libs/ajm/opus_decoder.h#L11-L15). Family 1 uses the conventional stream counts, coupled counts and channel map from [libopus 1.5.2's surround layout](https://github.com/xiph/opus/blob/v1.5.2/src/opus_multistream_encoder.c#L47-L55), passed to FFmpeg through an [RFC 7845 section 5.1](https://datatracker.ietf.org/doc/html/rfc7845#section-5.1) header with zero pre-skip and gain; gapless skipping remains controlled by AJM sideband parameters. FFmpeg returns PCM in its native speaker order. The implicit stream layout, PCM channel order and invalid family-0 channel count result are not verified on a console. NHL 27 (PPSA34063) passes `1, 48000, 255`. Family 255 with one channel is decoded as one mono stream, the same as family 0; this is assumed, since the stream count, coupled stream count and channel mapping that a family-255 Opus header carries ([RFC 7845 section 5.1.1](https://datatracker.ietf.org/doc/html/rfc7845#section-5.1.1)) are not passed. Only 48000 Hz, mapping families 0 and 1, and family 255 with one channel are implemented; other rates and families, and family 255 with more channels, throw

How a non-zero change ramps the ratio is not confirmed on a console (no source: KytyPS5 ignores it, prosper stubs it, the PS5 firmware does not export the batch builders to a payload): it is assumed to be added to the ratio after each emitted output frame, clamped at zero, and kept across batches. RIDE 4 (PPSA01599) passes one call with a change of 4.6e-7, so the exact rule matters little there.

 - [NGS2 sampler voice state flag EMPTY](../../../core/libs/prx/libSceNgs2.native/src/Render.cpp) (libSceNgs2.native) - a playing sampler voice that still accepts blocks (`CONTINUE`) and has played all queued blocks reports `INUSE|PLAYING|EMPTY` (0x20) and keeps playing, so blocks added later play on. PPSA18391 (engine: Clickteam Fusion) reads `state_flags & 0x22 != 2` from `sceNgs2VoiceGetState` as the end of a sound and only then reuses the voice. When the console sets and clears EMPTY, and whether it also reports it for other voice types, is unverified on hardware.
 - [NGS2 port matrix](../../../core/libs/prx/libSceNgs2.native/src/Render.cpp) (libSceNgs2.native) - a port without a matrix, or with a selected matrix whose levels were never set, mixes through a default channel map: mono reaches both stereo channels at -3 dB and the 5.1 and 7.1 centre, stereo folds to mono at -3 dB per side, and wider sources fold down with 0.5 and -3 dB gains. The map and the equivalence of an unset matrix with no matrix were measured from the PS4 firmware 11.00 `libSceNgs2.sprx`, not yet from the PS5 library. That library only accepts submixer and mastering voices with 1, 2, 6 or 8 channels, so the map into 3, 4, 5 or 7 channels throws. A matrix set with fewer levels than the destination needs still mixes only the rows it has

Only UserFx and UserFx2 modules on a single buffer are accepted: other module ids, more buffers, a module control handler, different input and output channel counts, setup flags and default rack options throw. Each module's state is a separate buffer, not the `state_offset` slice of the voice state, and `sceNgs2VoiceGetState` still throws for this rack. As in KytyPS5, UserFx2 process runs only on grains where an input produced samples, so an effect tail stops with the input and a pending flag 2 waits for the next audible grain
+- [NGS2 custom module ids](../../../core/libs/prx/libSceNgs2.native/src/Custom.cpp) (libSceNgs2.native) - a custom rack with a module id other than 0x13 (sampler rack), 0x1d and 0x1f (submixer rack) throws. Trails in the Sky 2nd Chapter (PPSA35169) creates a rack with module id 0x20 (`NGS2: custom module id 0x20 is not implemented`, #4246); which module it is, and its structure, are unknown.
 - [NGS2 reverb rack](../../../core/libs/prx/libSceNgs2.native/src/Reverb.cpp) (libSceNgs2.native, rack 0x2001) - follows the PS4 firmware 11.00 `libSceNgs2.sprx`, read and checked against its output at 11.025 to 48 kHz, including parameter changes during playback (differences at float rounding level); not yet compared with the PS5 library. Structure layouts come from [shadPS4](https://github.com/shadps4-emu/shadPS4)'s `ngs2_reverb.h` and the param ids 0x20010000 (setup) and 0x20010001 (I3DL2) from PPSA22520. Only the default `reverb_size` of 1 is handled, with its 14400-sample reflection buffer; other sizes and the library's half-rate mode throw. System sample rates below about 7.5 kHz, where an allpass delay would have no samples, throw. Setup only accepts equal input and output channel counts
 - [sceNgs2ReportRegisterHandler, sceNgs2ReportUnregisterHandler](../../../core/libs/prx/libSceNgs2.native/src/Unimplemented.cpp) (libSceNgs2.native, NIDs `uBIN24Tv2MI`, `nPzb7Ly-VjE`) are throwing stubs. The signatures (report type, handler, user data, out handle) and (report handle) follow [SharpProspero](https://github.com/SvenGDK/SharpProspero) and [shadPS4](https://github.com/shadps4-emu/shadPS4)'s `ngs2_report.h`. No report is produced yet, so registering a handler cannot be honoured. PPSA04540 imports both and registers a CPU load handler (type 5)

A sample rate of 0 and a null user data pointer throw, any other rate is accepted, and changing the rate while a sampler filter is enabled throws because the filter coefficients were computed for the old rate. Lock and unlock take the same lock as `sceNgs2RackLock`

 - [Resource registration](../../../core/libs/prx/libSceAgcDriver/Resource/src/Registration.cpp) (libSceAgcDriver) - registration always fails with `RESOURCE_REGISTRATION_UNAVAILABLE`, so the owner and resource queries, `sceAgcDriverSetResourceUserData`, `sceAgcDriverFindResourcesPublic` and `sceAgcDriverUnregisterAllResourcesForOwner` return the same error without reading their arguments. Their parameter lists follow the libSceGnmDriver counterparts and are unverified. `sceAgcDriverGetResourceRegistrationMaxNameLength` writes 0xfc and returns 0, as [prosper](https://github.com/mattias800/prosper) does from a title's registration configuration; the `uint32_t*` parameter matches the SDK wrapper `sce::Agc::ResourceRegistration::getMaxNameLength(unsigned int*)`. sharpemu writes 256 and KytyPS5 returns `RESOURCE_REGISTRATION_UNAVAILABLE`, so the value is unverified; a null output throws
 - [sceAgcDriverRegisterMultipleResources](../../../core/libs/prx/libSceAgcDriver/Resource/src/Registration.cpp) uses the existing unavailable-registration state and leaves caller memory untouched. Its four arguments (uint32 handle output, uint32 owner, descriptor pointer, uint32 count) follow the original PPSA34502 / 01.010.000 codzm call. The caller builds 40-byte descriptors and explicitly accepts 0x8A6C9018 with an invalid output handle. Enabled registration and console argument-validation precedence are unverified.
 - [Shader headers](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Shaders/ShaderRegistry.cpp) (libSceAgcDriver) - registration and ABI resolution read fixed header fields through aligned copies, so the header pointer itself may have any alignment. PPSA26344 passes headers 4 and 1 bytes past an 8-byte boundary, and PPSA01317 passes 4-byte-aligned headers to ABI resolution; console alignment requirements are unknown
+- [Registered shader types](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Shaders/ShaderRegistry.cpp) (libSceAgcDriver) - types 0, 1, 2, 4, 6 and 7 are prepared and type 5 is skipped. Any other type, such as type 8, is logged (`unsupported registered shader type 8; it is not prepared at registration`) and left unprepared at registration, and throws when it is used later. Hello Neighbor 2 (PPSA07426), Ad Infinitum (PPSA10600) and Ghostrunner (PPSA03685) register type 8 headers and run on past them; what a type 8 header describes is unknown, #1892 found no context registers in it.
 - [NGG vertex workgroups](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Shaders/ShaderRegistry.cpp) (libSceAgcDriver) - type-2 PRIMGEN programs using DS instructions or `s_barrier` are prepared with the draw's routing and primitive registers on the existing mesh path. The workgroup requirement follows [Mesa's NGG lowering](https://github.com/mihawk-99/PS5_Mesa/blob/b3588f78dd7fd46fbadc7ecd487e5f14d4213e4b/src/amd/common/nir/ac_nir_lower_ngg.c#L1135); the mesh path supplies LDS and two guest lanes per host invocation for wave64 on a 32-lane host subgroup. Console routing has not been measured. Passthrough and tessellation keep their existing paths; unsupported mesh assembly and subgroup budgets throw.
 - [Shader header copies](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Shaders/ShaderRegistry.cpp) (libSceAgcDriver) - a header bound for a draw or dispatch at another address than the registered one is accepted when its fixed fields match the registered header except `user_data`; the registered header's metadata is used. PPSA21567 binds such a copy of a vertex shader header with `user_data` set to null. Whether the console reads the copy's `user_data` is unknown
 - [HtileFillCovers](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - a fill is taken to cover a depth surface's whole HTILE when it spans 32 KiB per 1024x512 pixel block from DB_HTILE_DATA_BASE, the pipe-aligned SW_64KB_Z_X metadata extent AMD PAL's gfx10 addrlib gives for GB_ADDR_CONFIG 0x00100044 (1-8 samples, D16/D32); other metadata layouts are not decoded. A partial fill is ignored (the surface keeps its contents); not measured on the console.

 - [sceKernelGetModuleInfoForUnwind](../../../core/libs/prx/libkernel/Module/src/Module.cpp) (libkernel) - on Linux the tables come from `sceKernelGetModuleInfoFromAddr`, whose `eh_frame_size` includes the zero terminator, as measured on firmware 13.60 (reported in [#2419](https://github.com/boykopovar/AnyPS5/issues/2419), not reproduced here); on Windows it is assumed to stop before the terminator. LLVM libunwind's `CFI_Parser::findFDE` stops at the terminator or the length, whichever comes first, so it finds the same FDEs either way. Only the main executable and `.guest.prx` images report tables; other host images report none, as on Windows
 - [sceKernelGetModuleInfoForUnwind](../../../core/libs/prx/libkernel/Module/src/Module.cpp) (libkernel) - on Windows the `.ehmeta` tables and the image file name are cached per allocation base and dropped after a loader free (`dlclose`, `sceKernelStopUnloadModule`, the thread atexit release) when the module is no longer loaded. A table changed in place, or an image freed by anything other than the loader, is not noticed. An address inside an image of the Windows loader's module list whose tables are cached is resolved with `RtlPcToFileHeader` and no `VirtualQuery`; other addresses, and images without tables, still use `VirtualQuery`. The `.eh_frame` walk that finds its end is done once per image instead of once per call

Subject: [PATCH 0447/1000] perf(agc): free an import retired during its settle
 read after the read

Retiring a Windows import whose settle read was still running waited for
the read's batch under the imports mutex, so lookups on every thread
waited with it. The retired import is now kept with that batch and freed
once the batch has completed. Only a guest unmap of its memory still
waits for the batch, in the pin waiter, which waits for the main queue
there anyway.

The [buffers] profile line counts these retirements and the unmaps that
waited, apart from the imports of 1 MiB or more settled inside their
window, which the old wait counter mixed with the retirement waits.

agc_import_settle_retire replaces a 64 KiB window import with the import
of its whole range, 64 times, right after its settle read was submitted.
No replacement may wait, at least one must find the read running, and
the last import must return to the write watch.

Subject: [PATCH 0448/1000] test(agc): check that a settle read ends the
 driver's marking of an import

A Windows import under 1 MiB returns to the write watch once its settle
read has completed, though main-queue work submitted before the read may
have used the import first, and an earlier import of the same pages may
not have run its first use yet. On the NVIDIA driver (617.42) neither
marks the pages once the read has completed, so the rewatch needs no wait
for the main queue. The docs said the marking lasts until the import's
first GPU use completes; they now say that a completed GPU use ends it,
the settle read included.

agc_import_settle_first_use submits 4096 copies of a 64 KiB import on
the main queue before its settle read is queued. The import must return
to the write watch while the copies still run, and the driver must mark
none of its pages afterwards.

agc_import_settle_earlier_import records 4096 copies of a 64 KiB window
import, replaces it with the import of its whole 128 KiB range, and
submits the copies only once the range is back in the write watch. The
driver must mark none of the range's pages while they run. A driver that
keeps marking fails either test.

A smaller import is compared when it is made, so a title that maps, imports and unmaps a small buffer around every submission does not block its mapping thread. Its 4-byte read is queued instead: the next import lookup that holds `GpuMutex` while the imports match the registry (`settleUnwatchedImports`) records the queued reads into one batch on the settle queue, and once the batch's fence has signalled a later lookup returns the import's whole 64 KiB blocks to the write watch (`GuestMemory::Rewatch` drops their marks and stamps every block as a CPU store), except while storage results are pending over them. A settled import whose range had already left the watch returns the same way, and an import retired while its read is in flight is kept with that batch and freed once the batch has completed, without waiting for it; a guest unmap of its memory waits for the batch instead. Imports through a section alias keep tracking on the guest views, and every other Windows host import is compared. A device without such a queue keeps the comparisons.

 - [Pending storage-image results](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) are stored when something reads their memory, not when the GPU work that wrote them completes. A title that waits for that work, frees the image and reuses its memory can have the new data overwritten by the late store (#1970). A title's own CPU reads are not seen either, so a title that reads the results after waiting for a label reads stale memory. `APS5_STORE_AT_FLIP=1` stores every pending result at each flip and `APS5_STORE_AT_LABEL=1` before each label the GPU writes; both store every pending image, not only the ones the waited-for work wrote, and neither is on by default.
 - [Pending storage-image results over memory outside the write watch](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) leave to the CPU the 64 KiB blocks whose bytes differ from the ones saved at the upload, the fill, the image copy, the previous store or the moment their range left the watch (`Unwatch`, or a host import that does not stay watched), and the blocks the watch saw the CPU write before that moment. A store made on the GPU saves its bytes through a host-visible copy that becomes the saved bytes when its batch completes; a store or a refresh that needs them earlier waits for that batch. A unit without a write generation saves the guest bytes when results land in it outside the watch. One whose range leaves the watch while its results are pending, and ranges that leave the watch through a failed collect, have no saved bytes; storing such results throws.
 - Windows host-pointer imports of the guest mapping itself are compared instead of write-watched, except writable imports of private `MEM_WRITE_WATCH` memory when the import probe keeps the write watch and a settle queue exists: those of 1 MiB or more stay watched, and smaller ones return to the watch once their settle has completed (see Pages under an import window): a driver can mark imported pages dirty after the synchronous import window. Shared memory imported through a separate writable alias retains protection-based tracking on the guest views; driver access to the import alias does not disarm those views. [GuestMemory](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) excludes every overlapping 64 KiB tracker block while its backing is retained. A full block replaced by fresh private backing regains tracking and gets a new generation; protection changes, partial replacements and shared remappings do not restore it. Excluded blocks keep their write-watch marks as a hint only (`UntrackedHint`): a storage image or a sampled texture snapshot over them compares its bytes again after a mark in its range, a driver store, a mapping change or a recorded GPU write instead of at every collect epoch or lookup, and a mark the driver makes without a CPU store costs one comparison. This preserves CPU edits through byte comparisons but limits snapshot reuse on excluded blocks to draws of one collect epoch and disables unit shadows for them; restoring tracking on import retirement without replacing the backing remains unimplemented.
-- [Pages under an import window](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) (libSceAgcDriver) whose write protection was resolved while a host import that leaves its range watched was made are compared with the bytes they held before the import and count as stored over only when those differ. A CPU store of the bytes already there within the window cannot be told apart from an import that resolves the write protection without storing, as the NVIDIA driver (610.57.04) does for every imported page, so such a store does not win over pending results. Where host-pointer and dma-buf imports differ in whether they stay watched, a failed host-pointer import and the dma-buf import after it are two windows, and the pages the failed one resolved count as stored over. On Windows, the NVIDIA driver (617.42) marks every page of a host import of private `MEM_WRITE_WATCH` memory written, asynchronously, until the import's first GPU use completes. Such an import stays watched only after a 4-byte read of it on the settle queue has completed inside the window. Each one waits for that read, which keeps its window open for one round trip on the settle queue, so a same-value CPU store from another thread in that time counts as unchanged too. An import made where no settle queue exists is compared instead. An import of under 1 MiB is not settled inside its window, because the settle blocks the importing thread and a title that imports a 64 KiB buffer around every submission lost about 19 % of its frame rate to that wait (Dripl1x, #6060). It is compared until its read, submitted in a batch by a later import lookup under `GpuMutex` while the imports match the registry, has completed; a later lookup then returns its whole blocks to the write watch, each stamped as a CPU store, so whatever was derived from them while they were compared reads as changed once. Its blocks stay compared while storage results are pending over them, and those of an import retired before that stay compared.

 - [Sparse dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a shared-backed range larger than one 64 MiB udmabuf buffer is imported as one sparse buffer bound to the 64 MiB buffers, on a queue of its own when the device has a second family that binds sparse memory. The path is decided before anything is imported, and a failure after that throws. A range takes the single udmabuf import instead, which udmabuf's `size_limit_mb` refuses above 64 MiB by default so the range is copied, when its offset in the backing file is not a multiple of the buffer's sparse block size (64 KiB on RADV), when the sparse buffer does not accept every memory type a chunk import can have, when the backing file ends inside its last chunk, or when it is imported at map time on a device with no second family (the bind then needs the GPU mutex); the NVIDIA proprietary driver imports no dma-buf memory
 - [Unnormalized S# coordinates](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) - `FORCE_UNNORMALIZED` uses a Vulkan `unnormalizedCoordinates` sampler, so the S# LOD range, LOD bias and mip filter are not applied, which is exact only on a one-level view.
 - An [unnormalized S#](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) maps clamp mode 0 (repeat) on X and Y to clamp-to-edge as required by Vulkan unnormalized coordinates, and assigns the magnification filter when minification and magnification filters differ (since unnormalized coordinates sample at LOD 0). Anisotropy, TRUNC_COORD, MC_COORD_TRUNC and other clamp modes still throw. Secondary LOD bias (LOD_BIAS_SEC, bits [19:14]) is accepted and ignored, matching RDNA2 hardware measurements across explicit and implicit samples. High on Life (PPSA15388, #4736) uses secondary LOD bias and unnormalized coordinates with clamp mode 0 and differing min/mag filters during home base and city rendering.

Subject: [PATCH 0449/1000] feat(agc): rasterize a multisampled draw into
 one-sample targets at sample 0's locations

A draw whose rasterizer has more samples than its color or depth targets
threw "a color target's sample count differs from the rasterizer's" or
"the depth target's sample count differs from the rasterizer's". When
every target has one sample, MSAA_ENABLE is set, and there is no
alpha-to-coverage, no PS_ITER_SAMPLE and no sample-dependent pixel input,
only sample 0's coverage reaches the targets, so draw it with one sample
at sample 0's location in each pixel of the grid. One-sample depth images
are created sample-location compatible when the device allows it.

The tiled layout is assumed to be the 8-byte SW_64KB_R_X equation of `TextureSwizzleEquations.hpp` applied to full coordinates, as addrlib applies it, by analogy with the 32-bit scanout; `ColorTargetLayout` applies the equations to in-block coordinates, which for 8-byte texels differs in every odd 64-row block row (address bit 11 takes y bit 6) and for 16-byte texels also differs, so a float display buffer written through `WriteColorTarget` and presented from guest memory would show those rows misplaced. The values are assumed to be linear light and are encoded with the sRGB curve for the 8-bit output. Bits 32-39 of these formats are `0x06`, as in the 10-bit formats SharpProspero lists without sRGB transfer, while its sRGB formats have `0x00`, its 10-bit PQ formats `0x04` (with `0x07` in bits 40-47) and its float BT.2100 PQ formats `0x07`: they show only that these formats are not the sRGB ones. NaN and negative values give 0, values of 1 and above give 255, alpha is linear. Neither the layout nor the transfer is verified against console or title frames, and HDR output is not modelled. DCC metadata on a float buffer throws.

Subject: [PATCH 0450/1000] feat(agc): keep sample, sample-index and per-sample
 shading on the sample-zero path

A multisampled rasterizer drawing into one-sample targets keeps
PERSP_SAMPLE, LINEAR_SAMPLE and ANCILLARY inputs, and with PS_ITER_SAMPLE
also centroid inputs, since only sample 0's coverage reaches the targets.
Coverage inputs, and the sample index with POS_X_FLOAT or POS_Y_FLOAT,
still throw. The input rule for the non-iterated case follows
fdfawef324's proposal on #5907 (PPSA07411).

 - [Storage image write-back](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) stores the GPU results over a CPU-stamped range whose guest bytes equal the copy taken when the image's layers got their generation (images up to 1 MiB whose guest bytes were settled at that point, with no unit shadow, pending image results or recorded GPU store over them; other images keep the previous rule: the CPU's bytes win). A CPU store that rewrites the baseline value after the GPU changed it is not told apart from no store, and the GPU result wins there. The 1 MiB limit is a choice, not a console value.
 - [16-bit float display buffers](../../../core/libs/prx/libSceAgcDriver/Execution/src/DisplayBuffer.cpp) (libSceAgcDriver, libSceVideoOut) - pixel formats `0xC001000622000000` and `0xC001000600000000` are taken as R16G16B16A16 and B16G16R16A16 float, eight bytes per texel, as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/59183dbfa81ed7efdff6069177fed50de0552725/src/graphics/host_gpu/renderer/image/imageInfo.h) maps them and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/VideoOut/VideoOutTypes.cs) names them (`Rgba16Float`, `Bgra16Float`); PPSA11386 registers 3840x2160 tiled buffers of the first. The tiled layout is assumed to be the 8-byte SW_64KB_R_X equation of `TextureSwizzleEquations.hpp` applied to full coordinates, as addrlib applies it, by analogy with the 32-bit scanout; `ColorTargetLayout` applies the equations to in-block coordinates, which for 8-byte texels differs in every odd 64-row block row (address bit 11 takes y bit 6) and for 16-byte texels also differs, so a float display buffer written through `WriteColorTarget` and presented from guest memory would show those rows misplaced. The values are assumed to be linear light and are encoded with the sRGB curve for the 8-bit output. Bits 32-39 of these formats are `0x06`, as in the 10-bit formats SharpProspero lists without sRGB transfer, while its sRGB formats have `0x00`, its 10-bit PQ formats `0x04` (with `0x07` in bits 40-47) and its float BT.2100 PQ formats `0x07`: they show only that these formats are not the sRGB ones. NaN and negative values give 0, values of 1 and above give 255, alpha is linear. Neither the layout nor the transfer is verified against console or title frames, and HDR output is not modelled. DCC metadata on a float buffer throws.

Subject: [PATCH 0451/1000] test(agc): expect the color sample-count refusal
 for a one-sample target under a 2x scan without MSAA_ENABLE

#5882 lets a multisampled scan without MSAA_ENABLE through the earlier
check, so the draw is now refused where its one-sample color target meets
the rasterizer's sample count.

Subject: [PATCH 0455/1000] test(agc): wait for a result pending over the
 neighbour copy surface

The NeighbourCopied wait accepted any pending result once the surface
image was live, so a pending result of the source surface could end it.
It now waits for a pending result overlapping the surface's range.

Subject: [PATCH 0456/1000] feat(agc): keep the last submissions per queue and
 dump them on a stall or crash

A GPU hang or a crash in a title leaves no record of what the queues
were last given: APS5_TRACE_GPU prints every submission (too much to
leave on), and the WAIT_REG_MEM timeout message shows only the packet
before the wait on the waiting queue.

Each queue now keeps a ring of its last 16 submissions
(APS5_PM4_RING=<n>, 0 to 4096, 0 disables): the TraceMs time in tenths
of a millisecond, serial, size, guest address and a copy of the first
512 dwords after indirect buffers are inlined, recorded under the
driver lock next to the serial, REWIND tails included. The ring of a
queue and the failure report registration are set up at the top of
Submit, before any output is reserved, so recording under the lock
does not allocate. Disabled, Submit only tests a static flag; enabled,
it costs one bounded copy per submission.

DumpSubmissionRings decodes the kept dwords with Pm4::PacketWords and
the new Pm4::KnownName, which returns the decoder's names as views of
static strings (empty for an unknown opcode, printed as UNKNOWN_0x%02x);
Pm4::Name now builds its std::string from it. Every line is formatted
with integer and string conversions only into a 512-byte stack buffer
and written with one WriteFile / write(2) on the stderr handle, so the
dump does not allocate from the C runtime heap, lines from other
threads do not interleave and the CRT stream lock is not taken (the
rule of #3871). The header gives the number of queues and the ring
size, and each queue line the submissions recorded and kept.

libc gets a small registry of failure reports
(LibcRegisterFailureReport_nid_no_patch, Unregister, Run); Run runs
the registered reports the first time it is called and returns at once
after that. The Windows crash report runs it after the thread dump of
an unhandled exception, after SIGABRT (which also covers the
APS5_HANG_DUMP_SECS timed dump, since it aborts) and after an invalid
CRT parameter, so an abort after a reported exception does not print
the rings twice. The driver registers its dump at the first submission
and unregisters at static destruction; the dump there waits a bounded
time for each ring lock. What the crash-path dump cannot do (a ring
held by the crashed thread, rings corrupted by the crash, Linux) is
recorded in technical debt.

APS5_STALL_WATCHDOG_SECS=<n> (0 to 86400, 0 disables) makes a waiter
that has not progressed for n seconds dump the rings once per wait: a
WAIT_REG_MEM (progress as for APS5_GPU_WAIT_TIMEOUT_MS: another packet
runs or completes), a REWIND waiting for the title, and a compute
submission held behind queue 0. The last one prints under the driver
lock, so submissions and the other queues wait for it (USAGE.md says
so). Both variables are read at the top of Submit, so an invalid value
of either throws at the first submission and never later inside a GPU
worker. The order wait behind queue 0 releases its order hold on scope
exit, so a throwing dump cannot leave it counted.

No packet semantics change; packet sizes and names are those of the
existing decoder (PM4 type-3 header layout as in Mesa
src/amd/common/sid.h). The queue bound of Submit and of the rings is
one constant, SubmissionQueueEnd.

Tests: agc_driver_pm4_tests gets ten modes, each its own ctest:
agc_driver_pm4_ring (APS5_PM4_RING=4, six submissions on queue 0 and
two on 0x20: the dump holds #3..#6 and #1..#2 in order, nothing
older), agc_driver_pm4_ring_empty (one line), _ring_disabled (one
line), _ring_invalid and agc_driver_pm4_stall_watchdog_invalid
(APS5_STALL_WATCHDOG_SECS=1x: the submission throws and is not
executed), _ring_report (LibcRunFailureReports_nid_no_patch dumps the
rings), _ring_report_heap (Windows: with ucrtbase.dll's HeapAlloc and
HeapReAlloc imports counting calls from the reporting thread, the
failure report of a submission holding INDEX_BUFFER_SIZE names it and
allocates nothing, while Pm4::Name of the same header is seen
allocating), and with APS5_STALL_WATCHDOG_SECS=1 a WAIT_REG_MEM
(agc_driver_pm4_stall_watchdog), a REWIND (_stall_watchdog_rewind) and
a compute submission held behind a queue 0 rendering wait
(_stall_watchdog_order), each held for about 2.5 s, dump once and
complete when released. The PM4 catalog test checks KnownName against
every opcode and custom name. windows_backtrace_failure_report checks
that abort() runs the registered reports once and not an unregistered
one; windows_backtrace_failure_report_once that abort() does not run
them again after an earlier run. With the dump decoding through
Pm4::Name, agc_driver_pm4_ring_report_heap fails with "the failure
report allocated from the C runtime heap"; with Run resetting its
flag, windows_backtrace_failure_report_once prints the report twice.

 - An [unnormalized S#](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) maps clamp mode 0 (repeat) on X and Y to clamp-to-edge as required by Vulkan unnormalized coordinates, and assigns the magnification filter when minification and magnification filters differ (since unnormalized coordinates sample at LOD 0). Anisotropy, TRUNC_COORD, MC_COORD_TRUNC and other clamp modes still throw. Secondary LOD bias (LOD_BIAS_SEC, bits [19:14]) is accepted and ignored, matching RDNA2 hardware measurements across explicit and implicit samples. High on Life (PPSA15388, #4736) uses secondary LOD bias and unnormalized coordinates with clamp mode 0 and differing min/mag filters during home base and city rendering.
 - [Background link-time-optimized relink of library pipelines](../../../core/libs/prx/libSceAgcDriver/Execution/include/PipelineLinkOptimization.hpp) (libSceAgcDriver) is skipped on every GPU under NVIDIA's proprietary Vulkan driver (`VK_DRIVER_ID_NVIDIA_PROPRIETARY`), so those pipelines keep their fast-linked form. The optimized link loses the device when bound on an RTX 3080 (Ampere, #2866) and an RTX 4060 (Ada, #3434); an RTX 5060 and an RTX 5080 (Blackwell) on the same driver do not, so the scope is wider than the evidence. No standard Vulkan query tells the architecture apart, and the driver version that fixes it is unknown. `APS5_NO_PIPELINE_LTO` disables the relink on every driver.
 - [8_SRGB and 8_8_SRGB textures](../../../core/libs/prx/libSceAgcDriver/Graphics/src/TextureFormat.cpp) (libSceAgcDriver) that the device samples as R8_SRGB or R8G8_SRGB use its own decode, which need not match gfx1035: NVIDIA's R8_SRGB is one bf16 step off in 29 of 256 codes.
+- [PM4 submission rings](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Queues/SubmissionRing.cpp) (libSceAgcDriver) keep only the first 512 dwords of each submission, so the packets past them are not printed. The [failure report](../../../core/libs/prx/libc/src/FailureReport.cpp) dump does not allocate from the C runtime heap: packet names come from static strings, each line is formatted with integer and string conversions into a 512-byte stack buffer and written with one `WriteFile`. It still runs on whatever state the crash left. It waits about 100 yields for each ring's lock and otherwise prints that queue as busy, so a crash while recording a submission loses that queue's ring. It reads the rings without checking them, so a crash that corrupted them can fault inside the dump; such a fault during the report of an unhandled exception stops in that report's `Sleep(INFINITE)` and the process hangs instead of ending. The reports run at most once per process. Linux has no crash report: there the rings are printed only by `APS5_STALL_WATCHDOG_SECS`.
 - [WAIT_REG_MEM](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Synchronization/WaitMemory.cpp) reports a diagnostic after `APS5_GPU_WAIT_TIMEOUT_MS` without treating the timeout as completion. An unsatisfied wait keeps polling and checking driver failures; a missing producer can therefore leave its queue waiting indefinitely. Existing recorded-label shortcuts remain in use.
 - [COND_EXEC](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Packets/PacketExecution.cpp) reads its condition after the earlier packets of its queue complete. Without PFP_SYNC_ME the console's graphics PFP reads it ahead of the ME, so a title that races the read sees a later value here.
 - A [flip inside a COND_EXEC range](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Packets/CommandValidation.cpp) throws: the flip is reserved with the video output when the buffer is submitted, and how the console withdraws a skipped one is unknown.

 Set `APS5_CRASH_INDIRECT_MEMORY=1` before launching the executable to include up to 64 bytes from each pointer found in the register memory dump.

This additional dump is disabled when the variable is unset or empty.
 
+### GPU submission rings and stall dumps
+
+Each GPU queue keeps its last 16 command buffer submissions: when each was submitted, its serial, size and guest address, and a copy of its first 512 dwords after indirect buffers are inlined. `APS5_PM4_RING=<n>` keeps the last `n` instead, from 0 to 4096; 0 keeps none, and any other value stops the title at its first submission. The rings are printed to stderr, one line per submission and one per decoded packet, when the Windows crash report runs: an unhandled exception, `abort()`, an invalid CRT parameter or the timed dump of `APS5_HANG_DUMP_SECS`.
+
+With `APS5_STALL_WATCHDOG_SECS=<n>`, a queue that has waited `n` seconds without progress in a `WAIT_REG_MEM`, a `REWIND` or behind queue 0 prints the rings once for that wait, and the title keeps running. A `WAIT_REG_MEM` progresses while any other packet runs or completes, as for `APS5_GPU_WAIT_TIMEOUT_MS`. `n` is from 0 to 86400 and 0, the default, disables the watchdog; any other value stops the title at its first submission, as for `APS5_PM4_RING`. While the rings are printed for a queue held behind queue 0, new submissions and the other queues wait.
+
 ## Exit codes
 
 `0`: conversion succeeded or help was displayed. `1`: invalid arguments. `2`: conversion failed; the error is printed to stderr. With `--autorun`, successful conversion returns the launched application's exit code.

The mode returns 77 on Linux with a message that tools/check_skips.py does not accept as a device limitation, so the full Build failed the skip check.

Subject: [PATCH 0458/1000] perf(libSceAgcDriver): order in-place vertex inputs
 behind pending GPU writes with a barrier

An in-place draw input flushed pending GPU writes over its range on the
CPU before the bind, a submit-and-wait of the open batch when a dispatch
in it wrote the buffer. The CPU never reads a vertex buffer's bytes, so a
vertex input under a pending write is bound in place behind a barrier from
shader and transfer writes to vertex attribute reads, recorded before the
draw's rendering begins; index inputs keep the flush, since the highest
index is read on the CPU. Minecraft generates a vertex buffer with a
compute dispatch every frame and drew from it one CPU wait later.

Subject: [PATCH 0460/1000] docs(debt): record that guest thread priorities are
 not applied to host threads

The sched_get_priority_max/min entry was rewritten by each fix that
matched a PS5 measurement, until it described only behaviour that now
matches the console. What remains is the gap no entry named: the
priorities are recorded and reported but never reach the host
scheduler.

The console's SoC channel count and meanings are hardware-dependent and differ from the host's, the host sensors are not the console's, the ACPI reading is unavailable on many machines, and the storage temperature property is numbered 52 on Windows 10 2004 and later and 22 before it, so the mapping, the values and the unsupported-input error are unverified; the storage channel was checked against the drive's own SMART composite temperature on one NVMe host (`StorageDeviceTemperatureProperty`, 36 °C on a WD_BLACK SN7100). `sceKernelGetCpuTemperature` reports sensor 0.

 - [inet_pton, inet_ntop](../../../core/libs/prx/libkernel/Socket/src/AddressConversion.cpp) (libkernel) - the text forms are assumed to be those of FreeBSD 11.4 and are unverified on a console: `inet_pton` accepts only four decimal parts without leading zeros for `AF_INET` and the RFC 4291 forms for `AF_INET6` (one `::` standing for at least one group, a dotted-quad tail only as the last 32 bits, no zone id), and `inet_ntop` prints lowercase hex with the first longest run of two or more zero groups compressed, and a dotted tail only for `::a.b.c.d` and `::ffff:a.b.c.d`. They no longer depend on the host resolver library

 ### Functional
 
+- [Guest thread scheduling](../../../core/libs/prx/libkernel/Pthread/src/Thread.cpp) (libkernel) - the policies and priorities that `sched_get_priority_max`, `sched_get_priority_min`, `pthread_setschedparam` and `scePthreadSetschedparam` accept, and those a created thread takes, follow a PS5 (firmware 13.60), but they are only recorded and reported: they are not applied to host threads, so a title's priority order has no effect on host scheduling
 - [sceKernelMprotect, sceKernelMtypeprotect](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) (libkernel) over a range with a gap that is not registered in the allocation tracker protect the registered parts and skip the gap, and return 0, as FreeBSD 11.4's [`vm_map_protect`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/vm/vm_map.c) does (it has no check for holes); a range whose start is unmapped (also when later pages are mapped) returns `SCE_KERNEL_ERROR_EINVAL` (`mprotect`: `EINVAL`) because an existing test pins that for an unmapped start; FreeBSD answers 0 there too (`vm_map_protect` takes the next entry), so this errno is not taken from the source and was not changed. `sceKernelMprotect` threw for a gap before, which ended the title. Every part is checked for a GPU or image pin before the first one is protected; the parts are then protected one after the other, so a host protection failure in a later part leaves the earlier parts changed (FreeBSD's `vm_map_protect` cannot fail in its second pass). The behaviour on the console is not known. None of this was measured on a console.
 - [sceKernelMprotect protection bits](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) (libkernel) - bits outside `0x3F7` are dropped instead of refused, as FreeBSD 11's [`sys_mprotect`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/vm/vm_mmap.c#L606) does with `VM_PROT_ALL`. Onimusha: Way of the Sword (PPSA27836 01.000.001) maps direct memory with `0xf2` and then protects it with `0xfffffff2`. Not measured on a console; the map calls and `sceKernelMtypeprotect` still refuse undefined bits
 - [JIT shared memory](../../../core/libs/prx/libkernel/DirectMemory/Jit.cpp) (libkernel) - `sceKernelJitCreateSharedMemory`, `sceKernelJitCreateAliasOfSharedMemory` and `sceKernelJitMapSharedMemory` take the signatures of [Orbital](https://github.com/AlexAltea/orbital)'s `tools/ida/db_types.json` (name, length, maximum protection, descriptor out; descriptor, maximum protection, descriptor out; descriptor, protection, address in and out), which ps4sdk, ps5-jar-loader and the call sites in RetroArch PPSA99169, XPSemu PPSA97358 and VLC PPSA85300 match; SharpProspero declares the alias as returning the descriptor. The object is a host anonymous file shared by its descriptors (a `memfd` on Linux, a delete-on-close temporary file mapped as an executable section on Windows), the alias is a duplicate descriptor, and every map maps the whole object, so writes through one view show through the others; a non-null address is a hint, as in `mmap` without `MAP_FIXED`. Not measured on the console: a length that is zero or not a multiple of 16 KiB and protection bits other than CPU read, write and execute are `EINVAL`; an alias or a map asking for more than the descriptor's maximum protection (write and execute counting as read) is `EACCES`, as FreeBSD 11's `vm_map_protect` treats a protection past `max_protection`; a descriptor that is not a JIT object is `EBADF`. The name is ignored, the objects do not count against the flexible memory budget, `mprotect` of a view is not limited to the maximum protection, and `mmap` of the descriptors is unsupported, as for `shm_open`. On Linux the `memfd` is created without `MFD_EXEC`, which Linux 6.3 added and older kernels reject with `EINVAL`, and relies on the protection of the mapping: the flag only sets the file's execute permission bits, and the direct memory `memfd` is mapped executable the same way; a host with `vm.memfd_noexec` set to 2 refuses the creation and the call throws

The shader reads `map[key]` and switches over the image's prepared runtime modes. Each distinct T# becomes one element, up to `ImageElementBudget` and the device's capacity. An entry that does not decode, is multisampled or over budget, pairs a reducing sampler with a point-only mode, is an unnormalized or reducing S#, or whose surface has no mapped byte is poisoned: it reads zeros and reports a fault through the BDA fault buffer only when a lane selects it (`APS5_IMAGE_TABLE_STRICT=1` throws at the snapshot instead). The driver's `resolveImageTables` in [`ShaderResources.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) looks up or creates a texture per element and keeps the last four resolved tables per thread for reuse within one collect epoch while their memory is unchanged. Cached objects grow with their tables, so the resource cache keeps at most `ResourceCache::TableElementBudget()` table elements (65,536, `APS5_RESOURCE_CACHE_TABLE_ELEMENTS`) and evicts its least recently used table objects past that, and the dispatch cache evicts its least recently used entries while their captured words exceed `Driver::DispatchCacheBytes()` (256 MiB, `APS5_DISPATCH_CACHE_BYTES`).

Subject: [PATCH 0464/1000] ci(linux): size build and test parallelism to what
 the shared host has free

The self-hosted runners share one 32-thread host and were fixed at one job each, so
a build with many ccache misses compiled them one after another (686 misses took 37 min).
Pick jobs from the free CPUs and available memory (1 to 8, ctest at most 4) and pass a
load limit to ninja so a busy host backs off.

Subject: [PATCH 0465/1000] perf(agc): journal the pipelines of a run and build
 them ahead on the next one

A graphics pipeline the store builds or a compute pipeline a dispatch builds is
appended to pipelines.journal next to the shader cache entries, as the
materialized result of each stage (the specialized SPIR-V, bindings and push
constants) plus the recipe the pipeline was built from: the stages'
identities, vertex input layout, descriptor set layout keys and the state
fields the Pipeline constructor reads. When a VulkanDevice is created with a
window (a headless device waits for its first draw or dispatch, since the
window's device usually replaces it first) the journal is loaded and its
pipelines are built on a pool of threads while the title loads, so the first
draw or dispatch of a configuration seen on an earlier run finds its pipeline
resident instead of compiling it on the queue worker.

The pipeline stores key on RecompileResult::Identity, a hash of the module
words, specialization constants, subgroup width and bindings that is the same
on every run (SharedSpirv::ContentHash, computed once per shared module),
rather than on the process-lifetime variant ids; a generated stage is keyed
like any other. CachedPipeline builds outside the store's mutex and the
library parts and link are built outside the library store's mutex, so replay
threads and queue workers build in parallel; a concurrent build of the same
key keeps the first inserted. A replayed pipeline enters the store at its
least recently used end and a full store takes none, and its optimized relink
waits for the first draw that binds it, so the title's own pipelines come
first in both. The compute pipeline creation moves into
VulkanDevice::createComputePipeline, shared by dispatches and the replay. The
store key also covers the color component mapping, the depth target's sample
count and a depth bias clamp, which the constructor reads.

The file names the device it was written for (the properties the driver's
pipeline cache file is named by) and starts over for another; a torn tail is
cut at a record boundary; two runs sharing the directory take turns on a lock
file and keep each other's records; a read failure never starts the file
over. A device cancels its replay before it is replaced or destroyed, and a
replaced device destroys its pipelines then rather than at the driver's stop.

APS5_NO_PIPELINE_JOURNAL=1 disables it; APS5_PIPELINE_JOURNAL_THREADS,
APS5_PIPELINE_JOURNAL_ENTRIES (the first recorded), APS5_PIPELINE_STORE_ENTRIES
and APS5_PIPELINE_JOURNAL_MAX_MIB bound it; APS5_PROFILE_DRAW prints a
[pipeline-journal] summary. APS5_VERIFY_SET_LAYOUTS=1 now also checks a
dispatch's set layout against the one described from its shader. The lavapipe
test suite, which shares one cache directory, runs with the journal off except
for the journal's own tests.

Before the writable cache, a miss is also looked up in read-only prebuilt packs and loose entry folders under `shader_cache/prebuilt`; pack entries are ordinary encoded cache entries behind a sorted key-hash index, validated by magic, compiler source version and index checksum when mapped, and a miss or rejected entry falls through to the writable cache and the compiler. Cache format 35 also stores the finite stencil-reference set, its replay-safety proof and reserved push-data word in the artifact and binding layouts. Entries from formats 31 to 34 are rejected.
+- The Vulkan pipelines are journaled as well ([`PipelineJournal.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/PipelineJournal.cpp)): a graphics pipeline the store builds (`CachedPipeline`) or a compute pipeline a dispatch builds is appended to `pipelines.journal` next to the shader cache entries, as the materialized result of each stage (the specialized SPIR-V, bindings and push constants, through `ShaderDiskCache::EncodeResult`) plus the recipe the pipeline was built from (`GraphicsPipelineRecipe`: the stages' identities, vertex input layout, descriptor set layout keys and the state fields the `Pipeline` constructor reads, `CanonicalPipelineState`). When a `VulkanDevice` is created, the journal is loaded and its pipelines are built on a pool of `hardware_concurrency() / 2` threads (`APS5_PIPELINE_JOURNAL_THREADS`) while the title loads, so the first draw or dispatch of a configuration seen on an earlier run finds its pipeline resident. The pipeline stores key on `RecompileResult::Identity`, a hash of the module words, specialization constants, subgroup width and bindings that is the same on every run (`SharedSpirv::ContentHash`, computed once per shared module), rather than on the process-lifetime variant ids, and a graphics pipeline is built outside the store's mutex, so the replay threads and the queue workers build in parallel. A draw that arrives before its replayed entry builds the pipeline itself; the first inserted wins. A replayed entry enters the store at its least recently used end and a full store takes none, so the title's own pipelines are never evicted for a replayed one, and the optimized relink of a replayed pipeline (`OptimizedPipeline::Schedule`) waits for the first draw that binds it, so the relink thread serves the title's pipelines first. A device created without a window starts its replay at its first draw or dispatch rather than at creation, since `Driver::AttachWindow` usually replaces it before the title draws. The journal records a pipeline once (modules and recipes are deduplicated by content), keeps at most `APS5_PIPELINE_JOURNAL_MAX_MIB` (1024), replays the first `APS5_PIPELINE_JOURNAL_ENTRIES` recorded (1024, the pipeline store's bound, `APS5_PIPELINE_STORE_ENTRIES`; a run reaches those first), and is disabled with `APS5_NO_PIPELINE_JOURNAL=1` or without a shader cache directory. The file header names the device (`PipelineJournalDeviceFingerprint`, the properties the driver's pipeline cache file is named by), so a journal written for another GPU or driver is started over rather than replayed; appends and reads hold `pipelines.journal.lock` against another process sharing the directory, and a device cancels its replay before it is replaced (`PrepareForReplacement`) or destroyed, so a replaced headless device never inserts entries the window's device then sweeps. `APS5_PROFILE_DRAW=1` prints a `[pipeline-journal]` summary when the replay finishes and at teardown.
 - A compute shader whose LDS plus its lock dword exceeds the host's `maxComputeSharedMemorySize` is not given a `Workgroup` array. `Recompile` sets `ShaderInfo::sharedMemoryBytes` for it and the SPIR-V backend addresses the LDS in a coherent storage buffer at descriptor set 1 (`WorkgroupMemoryDescriptorSet`), with a slice of `RecompileResult::workgroupMemoryDwords` per workgroup, indexed by `WorkgroupID` and `NumWorkGroups`. `VulkanDevice` keeps one such buffer, sized from the dispatch dimensions, and binds it after the resource set; programs that fit keep using shared memory.
 - `Driver::RegisterShader` splits shader preparation in two. `PlanRegistered` runs on the registering guest thread: it validates the registers and entry point, decodes the code and builds the recompile request, so invalid registrations still fail there. The RDNA to IR translation and resource plan (`PrepareShader`) run on a background pool of `hardware_concurrency() / 2` detached threads (at least 2, 64 MiB stacks).
 - Queue 0's packet worker decodes, captures and prepares a draw and hands its recording (`Graphics::Draw` under the GPU lock) to a committer thread in [`DrawPipeline.cpp`](../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Draw/DrawPipeline.cpp), so the next packet is decoded while the previous draw is recorded. Each queued item carries the guest ranges it will write (`DrawWriteRanges`: written buffers and storage images, color targets with their DCC and CMASK, depth and stencil). A later packet that reads or writes one of those ranges, or that the pipeline can't order, drains it first; labels, submission ends, buffer fills and (with `APS5_PIPELINE_DMA=1`) DMA packets are queued as items instead. An exception thrown by a commit is rethrown on the worker at its next enqueue or drain, as an inline draw error would be. On by default; `APS5_PIPELINED_DRAWS=0` records every draw inline, and `APS5_EXACT_DRAW_WRITES=0` widens the color and depth ranges to estimates.

 - [Compute LDS beyond the device's shared-memory limit](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) (libSceAgcDriver) lives in a coherent storage buffer with one slice of `LDS bytes / 4 + 1` dwords per workgroup (the last dword is the atomic lock), shared by all such dispatches and grown in 1 MiB steps up to `maxStorageBufferRange`; a dispatch whose slices do not fit throws. It is slower than shared memory and its cost was not measured. An indirect dispatch of such a program always reads its group counts on the CPU. Its results are pinned against the in-limit semantics in `agc_driver_lds_beyond_device_limit`, not measured on hardware.
 - [AGC buffer allocations](../../../core/libs/prx/libSceAgcDriver/Graphics/src/BufferPool.cpp) retry host/device out-of-memory once after reclaiming idle pool buffers and fully unused slab blocks. Live buffers and blocks with live slots are retained. Live images and other retained resources have no global memory bound; allocation failure still throws when reclaim cannot satisfy the request.
+- [Pipeline journal](../../../core/libs/prx/libSceAgcDriver/Graphics/src/PipelineJournal.cpp) (libSceAgcDriver): the journal is append-only and never compacted, so a module a later run no longer builds pipelines from stays in the file until it is deleted, and the whole file is read into memory while the replay runs (its modules reference that buffer until the last replayed pipeline was built). Only the first `APS5_PIPELINE_JOURNAL_ENTRIES` pipelines recorded are replayed (a record is never rewritten, so a pipeline past the bound stays past it), and the pipeline store evicts the least recently used entry past `APS5_PIPELINE_STORE_ENTRIES` (1024 each): a title with more configurations rebuilds the rest at the draw as before. A compute pipeline is replayed over the set layout `DescribeSetLayouts` derives from the result's bindings, which a dispatch that finds it resident checks against its `ShaderResources` layout only under `APS5_VERIFY_SET_LAYOUTS=1`. Recording and replay are best effort: a record whose write fails is lost, an entry whose build fails is skipped, and both are counted in the `[pipeline-journal]` line rather than stopping the run. A replayed pipeline that the title never asks for again costs its build time and its driver memory (its optimized relink is deferred to its first draw, so a run whose first frames bind many replayed pipelines queues their relinks then); nothing ages recipes out of the file. Two runs sharing the file take turns under its lock file, but each only knows the modules it loaded or wrote itself, so a module the other run appended meanwhile may be appended again (the loader keeps the first copy). Records a run appends after another run's load are replayed by that run only after its next start. The file header's format number is the only guard against a change of the recipe codec, `CanonicalPipelineState` or the store key that keeps the structures' sizes (the recompiler's source version does not cover the driver's sources).
 - [Graphics pipeline libraries](../../../core/libs/prx/libSceAgcDriver/Graphics/src/PipelineLibrary.cpp) (libSceAgcDriver): a pipeline is fast-linked at the draw and relinked with `VK_PIPELINE_CREATE_LINK_TIME_OPTIMIZATION_BIT_EXT` on a background thread, and binds the optimized one from the next draw on. Draws recorded before that use the fast link, whose vertex stage keeps the outputs the fragment stage does not read: on RADV (Radeon 660M, Mesa 26.2.4) 346 of 483 Astro's Playroom vertex shaders paired with a fragment stage that reads none of them used more VGPRs (median 8 more, up to 2.5 times), and on an RTX 4090 13 of 15 PPSA36082 vertex shaders up to 68 instead of 38 (#2242). The optimized link compiles to the same code as a whole pipeline
 - [Prebuilt pipeline libraries](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) (libSceAgcDriver): each registered vertex or pixel shader in registration form gets its pre-rasterization or fragment-shader library built on one background thread, with a fixed state the draw may not use: triangle list, counter-clockwise front face, no depth clamp, depth bias or conservative rasterization, first provoking vertex, one sample. Libraries are kept until the device is torn down; on Astro's Playroom 1948 of them added 0.44 GB of peak memory on RADV.
 - [`APS5_THREAD_PRIORITY=rt`](../../../core/libs/prx/libSceAgcDriver/Execution/src/ThreadPriority.cpp) (libSceAgcDriver) lowers the process's hard `RLIMIT_RTTIME` when it is above `APS5_THREAD_RTTIME_US` or rtkit's `RTTimeUSecMax`, because [rtkit](https://github.com/heftig/rtkit/blob/c295fa849f52b487be6433e69e08b46251950399/rtkit-daemon.c#L592-L637) (`verify_process_rttime`) reads the hard limit from `/proc/<pid>/limits` and refuses real-time scheduling when it is higher. An unprivileged process cannot raise the hard limit again, so it stays lowered for the process and its threads even when rtkit then refuses the request (burst limit, user or start-time checks) and the thread throws. rtkit's `MaxRealtimePriority` and `RTTimeUSecMax` are read first, so an unreachable rtkit or a priority above its maximum leaves the limit untouched. The lowered limit only matters for threads that later run under a real-time policy

 Recompiled shaders and the Vulkan pipeline cache are kept in a `shader_cache/` directory beside the output executable, so later runs skip recompilation. Set `ANYPS5_SHADER_CACHE_DIR` to use another directory, or set `ANYPS5_NO_SHADER_CACHE` to any non-empty value other than `0` to disable both caches. Shaders are stored in a subdirectory named after the recompiler's source version; subdirectories of other versions unused for 14 days are removed the first time a run looks up a shader. The pipeline cache is one `vk-pipelines-*.bin` file per GPU and driver version. Deleting the directory is safe: it is rebuilt on the next run.
 
+### Pipeline journal

+Besides the recompiled shaders, the shader cache directory holds `pipelines.journal`: every Vulkan graphics pipeline the pipeline store kept and every compute pipeline a run built, with the specialized shader modules they were built from. The next run of the title builds those pipelines on background threads while it loads, so a draw or dispatch the earlier run already made does not compile its pipeline when it is first reached. The journal belongs to the GPU and driver that wrote it, like the driver's pipeline cache file next to it: a run on another GPU or driver version starts it over, and the driver's own pipeline cache decides how fast each pipeline is rebuilt. Two runs sharing the directory take turns on `pipelines.journal.lock`. `APS5_NO_PIPELINE_JOURNAL=1` disables recording and replay; `APS5_PIPELINE_JOURNAL_THREADS` sets the replay threads (half the CPU threads by default; `0` records without replaying), `APS5_PIPELINE_JOURNAL_ENTRIES` how many pipelines are replayed (the first recorded, which a run reaches first) and `APS5_PIPELINE_STORE_ENTRIES` how many graphics pipelines stay resident (1024 each), and `APS5_PIPELINE_JOURNAL_MAX_MIB` (1024) the file size at which recording stops. Deleting the file loses nothing but the head start. With `APS5_PROFILE_DRAW=1` a `[pipeline-journal]` line reports what was loaded, replayed and recorded.

 ### Storing GPU results at each flip
 
 GPU results in storage images and render targets stay on the GPU until something reads their memory. A title that frees such an image after waiting for its GPU work and reuses the memory can have its new data overwritten when the results are stored later ([TechnicalDebt](../dev/TechnicalDebt.md)). `APS5_STORE_AT_FLIP=1` stores every pending result when a display buffer is flipped, at the cost of one write-back per pending image and frame. Any other value stops the title at its first flip.

Subject: [PATCH 0466/1000] fix(agc): journal the sample location grid and
 per-sample shading of a pipeline

#5861 added both to the pipeline state and its store key; the recipe dropped them, so a
replayed pipeline keyed another configuration.

Subject: [PATCH 0469/1000] fix(agc): journal the pipeline state fields main
 added

The replayed stencil reference, the reversed blend, the quad sample masks
and the tessellation instance patches and draw parameters change the
pipeline a draw creates, so the recipe carries them; the file format is
bumped and the layout guards follow the new sizes.

Subject: [PATCH 0470/1000] test(agc): give the new program of
 compute_pipeline_outside_gpu_mutex its own module

Pipelines are now shared by every program that recompiles to the same
module, and a leading s_nop recompiles to the same one, so the second
dispatch reused the first pipeline. The new program also stores to the
second word.

Subject: [PATCH 0472/1000] perf(agc): dispatch-cache recipe hits as ordered
 commit items (APS5_PIPELINE_DISPATCH)

With pipelined draws, a DISPATCH_DIRECT on queue 0 whose dispatch-cache entry hits with a
recipe runs as an ordered commit item instead of draining the pipeline first. Misses, reads
that overlap writes still pending in the pipeline, verified data hits and writes that cannot
be ranged still drain. A dispatch that is resolved ahead (or adopted from a group resolved
ahead) and copy kernels keep the drained path; with the switch on, queue 0 does not resolve
dispatch groups ahead, since that drains the pipeline at every group. Off by default.
agc_driver_pipelined_dispatch counts drains per opcode (each dispatch drains with the switch
off); agc_driver_pipelined_dispatch_item checks that repeated dispatches do not drain, and that
a dispatch whose descriptor table a pending fill retargets drains and reads the new buffer.

 - `ShaderRecompiler::Recompile` keeps compiled variants in memory, and `ShaderDiskCache` stores them on disk so later runs reuse them. Before the writable cache, a miss is also looked up in read-only prebuilt packs and loose entry folders under `shader_cache/prebuilt`; pack entries are ordinary encoded cache entries behind a sorted key-hash index, validated by magic, compiler source version and index checksum when mapped, and a miss or rejected entry falls through to the writable cache and the compiler. Cache format 35 also stores the finite stencil-reference set, its replay-safety proof and reserved push-data word in the artifact and binding layouts. Entries from formats 31 to 34 are rejected.
 - A compute shader whose LDS plus its lock dword exceeds the host's `maxComputeSharedMemorySize` is not given a `Workgroup` array. `Recompile` sets `ShaderInfo::sharedMemoryBytes` for it and the SPIR-V backend addresses the LDS in a coherent storage buffer at descriptor set 1 (`WorkgroupMemoryDescriptorSet`), with a slice of `RecompileResult::workgroupMemoryDwords` per workgroup, indexed by `WorkgroupID` and `NumWorkGroups`. `VulkanDevice` keeps one such buffer, sized from the dispatch dimensions, and binds it after the resource set; programs that fit keep using shared memory.
 - `Driver::RegisterShader` splits shader preparation in two. `PlanRegistered` runs on the registering guest thread: it validates the registers and entry point, decodes the code and builds the recompile request, so invalid registrations still fail there. The RDNA to IR translation and resource plan (`PrepareShader`) run on a background pool of `hardware_concurrency() / 2` detached threads (at least 2, 64 MiB stacks).
-- Queue 0's packet worker decodes, captures and prepares a draw and hands its recording (`Graphics::Draw` under the GPU lock) to a committer thread in [`DrawPipeline.cpp`](../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Draw/DrawPipeline.cpp), so the next packet is decoded while the previous draw is recorded. Each queued item carries the guest ranges it will write (`DrawWriteRanges`: written buffers and storage images, color targets with their DCC and CMASK, depth and stencil). A later packet that reads or writes one of those ranges, or that the pipeline can't order, drains it first; labels, submission ends, buffer fills and (with `APS5_PIPELINE_DMA=1`) DMA packets are queued as items instead. An exception thrown by a commit is rethrown on the worker at its next enqueue or drain, as an inline draw error would be. On by default; `APS5_PIPELINED_DRAWS=0` records every draw inline, and `APS5_EXACT_DRAW_WRITES=0` widens the color and depth ranges to estimates.

A later packet that reads or writes one of those ranges, or that the pipeline can't order, drains it first; labels, submission ends, buffer fills and (with `APS5_PIPELINE_DMA=1`) DMA packets are queued as items instead. With `APS5_PIPELINE_DISPATCH=1` (off by default), a `DISPATCH_DIRECT` whose dispatch-cache entry hits with a recipe is queued as an item too, carrying the dispatch's written buffers and storage images (`DispatchWriteRanges`); the capture and the cache lookup stay on the worker and the recipe is recorded on the committer. A dispatch still drains when its lookup misses, when what it reads overlaps a write still pending, when the hit is verified against data or when its writes cannot be ranged (bindless access, GDS, fault buffer). An exception thrown by a commit is rethrown on the worker at its next enqueue or drain, as an inline draw error would be. On by default; `APS5_PIPELINED_DRAWS=0` records every draw inline, and `APS5_EXACT_DRAW_WRITES=0` widens the color and depth ranges to estimates.
 - The shader registry maps a code address to every header registered for that code, in registration order. Static, graphics and rectangle ABI resolution pick the header at the bound address (or one equal to it, `SameHeader`, which also takes a hull header fused by `sceAgcFuseShaderHalves` (type 3) as the registered back half (type 7) it copies, the fused registers aside; graphics ABI resolution then uses the fused header's shader registers); draws and dispatches pick the program by the stage's binary type (`RegisteredProgram`), and a front entry matching both type 2 and type 4 throws. Within a type the last registration wins; re-registering an identical earlier header makes its snapshot current again without preparing it again, and changed code drops the older headers.
 - The snapshot is published as pending. `SourceHandleFor`, `InvocationFor` and `ShaderPreparationTransaction::Edit` / `Read` wait for the pending job before reading `PreparedShaders`, and rethrow its failure. `APS5_SYNC_SHADER_PREPARE=1` prepares on the registering thread instead.
 - On devices with graphics pipeline libraries (`SpirvTarget::registrationModules`), a vertex or pixel artifact is emitted in registration form: the buffer V# words, image modes, swizzles and mip ranges, depth-compare state, export mappings and vertex component selectors it used to specialize on per draw are read at run time (image `ResourceMetadata` and a few state dwords in the shader data), descriptor heaps keep every element in place (an unused one gets a null or placeholder descriptor), and the pixel stage's bindings live in descriptor set 1 so each stage's library depends only on its own set layout (`INDEPENDENT_SETS`). An artifact above `registrationWordLimit` SPIR-V words is re-emitted specialized, and `CompiledShaderArtifact::registrationModule` records which form it has. For artifacts in registration form, `RegistrationResult` materializes the module once, and `PrebuildStageLibrary` builds its pre-rasterization or fragment-shader library on a separate one-thread pool (`APS5_PREBUILD_THREADS`) with a fixed default state, pairing it with a stub stage. A later draw with that state finds both libraries in the store and only links.

Subject: [PATCH 0476/1000] fix(recompiler): terminate pixel invocation on BDA
 fault when supported

Pixel invocations stopped by a BDA fault now end with OpTerminateInvocation when the target offers SPV_KHR_terminate_invocation, and keep OpKill otherwise. OpKill is not enough on AMD driver branch 21045, where a guest atomic after the kill still lands once per faulting pixel.

Based on the approach in poonasor/AnyPS5@73969879.

Subject: [PATCH 0477/1000] feat(agc): gate SPV_KHR_terminate_invocation on
 shaderTerminateInvocation

Shader validation accepts the extension only in fragment shaders and only when the device enabled shaderTerminateInvocation. The flag is part of the validation memo key.

Subject: [PATCH 0478/1000] fix(agc): validate OpTerminateInvocation itself,
 not only its extension

The validator only checked SPV_KHR_terminate_invocation when it saw the
OpExtension, so a module using OpTerminateInvocation without declaring
the extension, or in a non-fragment stage, was accepted. Require the
fragment stage, the enabled shaderTerminateInvocation feature and the
declared extension at the instruction itself.

Subject: [PATCH 0480/1000] feat(agc): enable
 VK_KHR_shader_terminate_invocation on the device

The device queries and enables shaderTerminateInvocation when available, advertises SPV_KHR_terminate_invocation to the recompiler and validation, and the shader device profile rejects a target that advertises the extension without the enabled feature.

Based on the approach in poonasor/AnyPS5@73969879.

Subject: [PATCH 0485/1000] feat(shader): store D16 data to SINT storage images

image_store with D16 data to a storage image of a SINT format threw
"stores 16-bit data to an image of a SINT format", both when the
descriptor is decoded and in the SPIR-V image emitter, and the runtime
image modes left out the SINT conversions for such images. God of War
Ragnarok (PPSA08330) stops on it in compute shader 0x1052a17900 right
after its MFSR setup.

Each 16-bit half is now converted like the D16 format buffer stores
(EmitD16StoreComponent): sign-extended, then saturated to the
component width as for 32-bit data. The buffer form was measured on
RDNA2 in #331; the image form is not measured (TechnicalDebt).

agc_driver_image_store_sint now stores D16 data with DMASK 0xf and 0x5
to all eight SINT formats and after an image_atomic_add on 32_SINT,
instead of expecting the refusal.

They follow the shader's float mode, measured on RDNA2 (gfx1035) in all eight combinations of `IEEE_MODE` and kept/flushed f32 and f16 denormals over 768 special and 1,024 random rows. With IEEE=1 a NaN operand is returned quieted; with IEEE=0 it is returned unquieted, except that v_interp_p2_f16's f16 result is always quiet.

Denormal modes 1 and 2 (flush only inputs or only outputs) and rounding other than to nearest even are not measured and throw. An unknown mode follows IEEE=0 with denormals kept. Lavapipe has no barycentrics, so the draw test is skipped in CI; `agc_driver_interpolation_modes` checks the arithmetic in every mode against the hardware rows on any device with Float64.

Any other read of them or of a raw vertex parameter takes the weights and the three vertex values from a [generated geometry stage](../../../core/shader/recompiler/SpirvBackend/src/BarycentricGeometryShader.cpp), which needs `geometryShader` and a vertex shader before it: tessellation, mesh and rect-list pipelines, primitives other than triangles, more than 32 fragment input locations and interfaces beyond the device's geometry limits throw.

Shaders with f64 instructions declare `DenormPreserve` for 64-bit floats only when `shaderDenormPreserveFloat64` is true and Vulkan reports `denormBehaviorIndependence` as `ALL`; other independence modes are not handled by the current backend because they require coupled execution modes.

Subject: [PATCH 0488/1000] fix(agc): note where a map-time settle blocks, and
 expect settles only for dma-buf imports

An import made at map time settles inside the guest's map call, so the mapping thread waits while the kernel maps the pages. A device that imports shared memory through host pointers settles nothing, so the test expects a settle only for a dma-buf import.

 - [Pending storage-image results over memory outside the write watch](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) leave to the CPU the 64 KiB blocks whose bytes differ from the ones saved at the upload, the fill, the image copy, the previous store or the moment their range left the watch (`Unwatch`, or a host import that does not stay watched), and the blocks the watch saw the CPU write before that moment. A store made on the GPU saves its bytes through a host-visible copy that becomes the saved bytes when its batch completes; a store or a refresh that needs them earlier waits for that batch. A unit without a write generation saves the guest bytes when results land in it outside the watch. One whose range leaves the watch while its results are pending, and ranges that leave the watch through a failed collect, have no saved bytes; storing such results throws.
 - Windows host-pointer imports of the guest mapping itself are compared instead of write-watched, except writable imports of private `MEM_WRITE_WATCH` memory of 1 MiB or more when the import probe keeps the write watch and a settle queue exists (see Pages under an import window): a driver can mark imported pages dirty after the synchronous import window. Shared memory imported through a separate writable alias retains protection-based tracking on the guest views; driver access to the import alias does not disarm those views. [GuestMemory](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) excludes every overlapping 64 KiB tracker block while its backing is retained. A full block replaced by fresh private backing regains tracking and gets a new generation; protection changes, partial replacements and shared remappings do not restore it. Excluded blocks keep their write-watch marks as a hint only (`UntrackedHint`): a storage image or a sampled texture snapshot over them compares its bytes again after a mark in its range, a driver store, a mapping change or a recorded GPU write instead of at every collect epoch or lookup, and a mark the driver makes without a CPU store costs one comparison. This preserves CPU edits through byte comparisons but limits snapshot reuse on excluded blocks to draws of one collect epoch and disables unit shadows for them; restoring tracking on import retirement without replacing the backing remains unimplemented.
 - [Pages under an import window](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) (libSceAgcDriver) whose write protection was resolved while a host import that leaves its range watched was made are compared with the bytes they held before the import and count as stored over only when those differ. A CPU store of the bytes already there within the window cannot be told apart from an import that resolves the write protection without storing, as the NVIDIA driver (610.57.04) does for every imported page, so such a store does not win over pending results. Where host-pointer and dma-buf imports differ in whether they stay watched, a failed host-pointer import and the dma-buf import after it are two windows, and the pages the failed one resolved count as stored over. On Windows, the NVIDIA driver (617.42) marks every page of a host import of private `MEM_WRITE_WATCH` memory written, asynchronously, until the import's first GPU use completes. Such an import stays watched only after a 4-byte read of it on the settle queue has completed inside the window. Each one waits for that read, which keeps its window open for one round trip on the settle queue, so a same-value CPU store from another thread in that time counts as unchanged too. An import made where no settle queue exists, and an import of under 1 MiB, is compared instead: the settle blocks the importing thread, and a title that imports a 64 KiB buffer around every submission lost about 19 % of its frame rate to that wait (Dripl1x, #6060). Settling without blocking the importing thread (submit the read, keep the import compared until its fence signals, then switch it to the write watch) is not implemented.
-- [Settled dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a dma-buf import of 1 MiB or more is read by a 4-byte copy on the settle queue right after it is made (`settleImport`), so the kernel maps its pages for the GPU there and not in the first submission that uses it (about 2 s for a 3 GiB import on RADV). The import's buffer is shared with the settle queue's family. An import made from a submission settles under the GPU mutex, so its frame still pays for it; a smaller import, and every import on a device with no settle queue (one without a copy-capable queue besides the main one), pays in its first submission

The import's buffer is shared with the settle queue's family. An import made at map time settles on the guest thread that maps the range, inside its map call, so that thread waits while the kernel maps the pages: 0.47 to 2.2 s for the 3 GiB range of Hades (PPSA03355) and 0.49 to 4.3 s for the 4.5 GiB range of ASTRO BOT (PPSA21567) on RADV. Both titles map these ranges at start-up; a title that maps large ranges during gameplay stalls its mapping thread for as long. An import made from a submission settles under the GPU mutex, so its frame still pays for it; a smaller import, and every import on a device with no settle queue (one without a copy-capable queue besides the main one), pays in its first submission. A range imported through a host pointer, as lavapipe imports shared memory, is not settled
 - [Sparse dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a shared-backed range larger than one 64 MiB udmabuf buffer is imported as one sparse buffer bound to the 64 MiB buffers, on a queue of its own when the device has a second family that binds sparse memory. The path is decided before anything is imported, and a failure after that throws. A range takes the single udmabuf import instead, which udmabuf's `size_limit_mb` refuses above 64 MiB by default so the range is copied, when its offset in the backing file is not a multiple of the buffer's sparse block size (64 KiB on RADV), when the sparse buffer does not accept every memory type a chunk import can have, when the backing file ends inside its last chunk, or when it is imported at map time on a device with no second family (the bind then needs the GPU mutex); the NVIDIA proprietary driver imports no dma-buf memory
 - [Unnormalized S# coordinates](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) - `FORCE_UNNORMALIZED` uses a Vulkan `unnormalizedCoordinates` sampler, so the S# LOD range, LOD bias and mip filter are not applied, which is exact only on a one-level view.
 - An [unnormalized S#](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) maps clamp mode 0 (repeat) on X and Y to clamp-to-edge as required by Vulkan unnormalized coordinates, and assigns the magnification filter when minification and magnification filters differ (since unnormalized coordinates sample at LOD 0). Anisotropy, TRUNC_COORD, MC_COORD_TRUNC and other clamp modes still throw. Secondary LOD bias (LOD_BIAS_SEC, bits [19:14]) is accepted and ignored, matching RDNA2 hardware measurements across explicit and implicit samples. High on Life (PPSA15388, #4736) uses secondary LOD bias and unnormalized coordinates with clamp mode 0 and differing min/mag filters during home base and city rendering.

Subject: [PATCH 0490/1000] fix(agc): journal the mesh output primitive size

#5884 added MeshConfiguration::outputPrimitiveSize, and #5875's pipeline
journal guards the layouts it encodes. The two merged separately, so on
Linux with libstdc++ PipelineJournal.cpp no longer compiles:
MeshConfiguration is 40 bytes, ShaderStages (which holds an optional
one) 112. The guards now name those sizes, and the recipe codec writes
and reads the new field, so a replayed line-strip geometry pipeline
keeps its two-vertex primitives.

Subject: [PATCH 0491/1000] feat(ssl): run TLS 1.2 client connections over Mbed
 TLS

sceSslConnect performs the client handshake on the host socket that the
guest number maps to in the libkernel or libSceNet socket table, and
sceSslRead and sceSslWrite carry application data. Session state comes
from the context's memory pool, and the server is verified against the
CAs loaded with sceSslLoadCert; a loaded client certificate is sent when
the server asks for one.

libkernel exports KernelLookupSocketNative_nid_no_patch, which checks
its own socket table before the one libSceNet registers. Pools take a
lock so connections can allocate outside the library lock.

TLS 1.3 is compiled out. A missing CA, a verify callback, would-block
sockets and every failure whose console code is unknown throw, as
recorded in the libSceSsl debt entry.

-- [sceSslCreateConnection, sceSslDeleteConnection, sceSslSetVerifyCallback, sceSslConnect, sceSslRead, sceSslWrite](../../../core/libs/prx/libSceSsl/Export.cpp) (libSceSsl) - imported by `ffmpeg.prx`. The repository has no TLS client, so a connection only records its context, socket, host and verification callback, and `sceSslConnect`, `sceSslRead` and `sceSslWrite` throw `NotImplemented_nid_no_patch(__func__)` until there is a transport. Signatures follow [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/60977b29103452b9681ae10c7a9011d44965bf16/src/SharpProspero/Interop/Net/Http.cs#L195-L252), which also says the socket stays open after `sceSslDeleteConnection`. An unknown context returns `SSL_ERROR_INVALID_ID` (0x8095F006), as `sceSslGetMemoryPoolStats` does on the console and as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/4865dd92ca6b6bb907748f125883093af038f53b/src/libs/network.cpp#L2688-L2720) and [sharpemu](https://github.com/sharpemu/sharpemu/blob/29021b5a71bbc80f262d887e6ba18b3a72963f49/src/SharpEmu.Libs/Network/SslExports.cs#L41-L54) return for other context calls; for an unknown connection, a connection whose context was terminated and a null host the console's codes are unknown, so these throw. The socket is not checked when the connection is created, `sceSslTerm` leaves the context's connections to `sceSslDeleteConnection`, and `sceSslSetVerifyCallback` accepts any callback, null included, and returns 0; none of this is verified on the console. `SSL_ERROR_BEFORE_INIT` (0x8095F001) is never returned, as the library keeps no state apart from its contexts

An unknown context returns `SSL_ERROR_INVALID_ID` (0x8095F006), as `sceSslGetMemoryPoolStats` does on the console and as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/4865dd92ca6b6bb907748f125883093af038f53b/src/libs/network.cpp#L2688-L2720) and [sharpemu](https://github.com/sharpemu/sharpemu/blob/29021b5a71bbc80f262d887e6ba18b3a72963f49/src/SharpEmu.Libs/Network/SslExports.cs#L41-L54) return for other context calls; for an unknown connection, a connection whose context was terminated and a null host the console's codes are unknown, so these throw. `sceSslConnect` runs a TLS 1.2 client handshake with Mbed TLS 3.6.7 over the host socket that the guest number maps to in the libkernel or libSceNet socket table, and `sceSslRead` and `sceSslWrite` carry application data over it. TLS 1.3 is compiled out: SharpProspero's `SceSslVersion` ends at TLS 1.2, and Mbed TLS 1.3 needs PSA crypto state that is process-wide rather than allocated from a context's pool. Connection state is allocated from the context's pool and returned to it by `sceSslDeleteConnection`; a connection keeps the pool alive after `sceSslTerm`. The server is verified against the CAs loaded with `sceSslLoadCert`: chain, validity dates and the host name the connection was created with, which is also sent as SNI. A client certificate loaded with `sceSslLoadCert` is sent when the server asks for one. With no CA loaded `sceSslConnect` throws, because no root bundle is shipped and the console's built-in roots are unknown. With a verify callback set it throws: SharpProspero describes the arguments as an id, bits saying what failed, the chain, its length and the user argument, with a negative return failing the handshake with that value, but whether the id is the context or the connection, the bit values, the chain element type and when the callback runs are unknown. Handshake, verification and socket failures, a second `sceSslConnect`, a read or write before the handshake, a descriptor that is not a socket, a null buffer, write flags other than 0 and read flags other than 0 and `MsgFlagPartialRead` (1) throw, as their console codes are unknown; `MsgFlagPeek` (3) is not implemented. A non-blocking socket that would block throws, and so does a libSceNet socket whose `SO_RCVTIMEO` or `SO_SNDTIMEO` expires, as libSceNet sets them on the host socket; libkernel keeps them above the host socket, so they do not bound SSL reads and writes on a libkernel socket. `sceSslRead` returns what one Mbed TLS read delivers, up to `len`, with flags 0 and with `MsgFlagPartialRead` alike; SharpProspero describes `sceSslRead` as reading up to `len` but `MsgFlagPartialRead` as returning before the buffer is full, so whether flags 0 waits to fill the buffer is unknown. It returns 0 after the server's close_notify and also when the transport ends without one. `sceSslWrite` sends all of `len`, capped at `INT_MAX`, and returns the count. A connection serializes its reads and writes, so a read blocked in one thread holds back a write on the same connection from another. `sceSslDeleteConnection` sends no close_notify. The socket is not checked when the connection is created, `sceSslTerm` leaves the context's connections to `sceSslDeleteConnection`, and `sceSslSetVerifyCallback` accepts any callback, null included, and returns 0. None of this is verified on the console. `SSL_ERROR_BEFORE_INIT` (0x8095F001) is never returned, as the library keeps no state apart from its contexts

Subject: [PATCH 0493/1000] fix(recompiler): keep spanned wave invocations
 running after a BDA fault

A spanned wave64 program exchanges ballots and shuffles through
workgroup-scope barriers. When a BDA fault stopped one invocation early,
the other 63 would wait at the next barrier forever. Spanned programs
now keep every invocation running and read zeros after a fault, as
programs with wave LDS barriers already do.

 - [SDWA source selects on `v_cvt_f32_ubyte1`, `v_cvt_f32_ubyte2` and `v_cvt_f32_ubyte3`](../../../core/shader/recompiler/RdnaDecoder/src/RdnaVectorOpDecoder.cpp) (shader recompiler) - byte N is taken from source 0 after `SRC0_SEL` and `SRC0_SEXT` select and extend it, since SDWA supplies source 0 (RDNA 2 ISA guide 6.8 and 13.3.7) and the opcode reads `S0.u[8N+7:8N]` (12.8). Not measured on hardware.
 - [Flag structurization](../../../core/shader/recompiler/ControlFlow/src/Structurizer.cpp) (shader recompiler) - a graph that every structurizer attempt refuses, irreducible and non-terminating graphs included, is rebuilt with one reach flag per block and one again flag per loop (`structurizeWithFlags`): each block keeps one copy and runs behind a guard on its flag, and each strongly connected component becomes a loop whose single latch repeats it while a back edge set its flag. The output has about 8 times the input's blocks and one route variable per block, and ends in an empty Return that never runs. Only blocks that start the top-level order unconditionally run unguarded, so resource planning also sees the static paths that skip a guarded block and can plan extra descriptor candidates for them. The attempts still run first. Shared merge splitting refuses an attempt once the graph has grown past 16 times its block count at the start of splitting (at least 64 blocks); succeeding attempts grew at most 10.6 times on random graphs of up to 128 blocks, and an attempt that would succeed only beyond the budget leaves the graph to a later attempt or to this construction. Splitting that adds one block per round stays within that budget until its 4 rounds per block run out, so the attempts can still take more than 10 s (9 of 2,000 random graphs of up to 128 blocks, 63 s at most). `APS5_FORCE_STRUCTURIZER_FALLBACK=1` builds every graph this way, for tests
 - [Scalar buffer descriptors](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) use only the base address, stride and record count for resources accessed exclusively by scalar loads; their fourth word is normalized to zero, following AMD RDNA2 ISA section 7.2.2. Vector and mixed accesses retain descriptor validation. Native Vulkan readbacks cover ignored fourth-word fields on Windows/NVIDIA; their console behavior has not been measured.
+- [Spanned wave64 compute](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvSubgroup.cpp) (shader recompiler) - `APS5_SPANNED_WAVE=1`, off by default, runs a single-wave wave64 compute program at one lane per invocation on a 32-lane host subgroup and exchanges ballots, shuffles and reductions between the two host subgroups through workgroup memory and barriers. On Ghost of Yōtei (PPSA26344, RTX 4090, Windows, with #6402's image-table stores, which the title needs to get that far), the first dispatch of the second variant of the compute program at 0x80001e5f00 (about 830k SPIR-V words, 125-145 storage images through an image table) lost the device (NVIDIA TDR, `vkQueueSubmit` returns `VK_ERROR_DEVICE_LOST`) in five runs, with warm and cold shader caches; without the variable the same dispatch runs. The device-fault report gives no instruction address the module maps to, so the cause is not attributed. Keeping a faulting invocation running in its spanned wave (`bdaStopsInvocations` off for spanned programs) and #6416 did not change it. Stray (PPSA02101) on Intel ANV and a Demon's Souls (PPSA01342) request replay showed no fault

Subject: [PATCH 0496/1000] fix(recompiler): ballot a spanned wave's LDS lock
 loop within its host subgroup

The lock loop that emulates 64-bit LDS atomics runs only on the lanes
the guest's exec mask keeps, so a spanned wave's barrier-based ballot
there was not reached by both host subgroups. When one subgroup had no
active lane the other one paired its barriers with unrelated ones and
left the loop with lanes still pending, or the GPU hung (Ghost of
Yotei, program 0x80003af600). The elect and the lock are already per
host subgroup, so each subgroup now loops until its own lanes are done.

Not measured on hardware.
 - [Flag structurization](../../../core/shader/recompiler/ControlFlow/src/Structurizer.cpp) (shader recompiler) - a graph that every structurizer attempt refuses, irreducible and non-terminating graphs included, is rebuilt with one reach flag per block and one again flag per loop (`structurizeWithFlags`): each block keeps one copy and runs behind a guard on its flag, and each strongly connected component becomes a loop whose single latch repeats it while a back edge set its flag. The output has about 8 times the input's blocks and one route variable per block, and ends in an empty Return that never runs. Only blocks that start the top-level order unconditionally run unguarded, so resource planning also sees the static paths that skip a guarded block and can plan extra descriptor candidates for them. The attempts still run first. Shared merge splitting refuses an attempt once the graph has grown past 16 times its block count at the start of splitting (at least 64 blocks); succeeding attempts grew at most 10.6 times on random graphs of up to 128 blocks, and an attempt that would succeed only beyond the budget leaves the graph to a later attempt or to this construction. Splitting that adds one block per round stays within that budget until its 4 rounds per block run out, so the attempts can still take more than 10 s (9 of 2,000 random graphs of up to 128 blocks, 63 s at most). `APS5_FORCE_STRUCTURIZER_FALLBACK=1` builds every graph this way, for tests
 - [Scalar buffer descriptors](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) use only the base address, stride and record count for resources accessed exclusively by scalar loads; their fourth word is normalized to zero, following AMD RDNA2 ISA section 7.2.2. Vector and mixed accesses retain descriptor validation. Native Vulkan readbacks cover ignored fourth-word fields on Windows/NVIDIA; their console behavior has not been measured.

On Ghost of Yōtei (PPSA26344, RTX 4090, Windows, with #6402's image-table stores, which the title needs to get that far), the first dispatch of the second variant of the compute program at 0x80001e5f00 (about 830k SPIR-V words, 125-145 storage images through an image table) lost the device (NVIDIA TDR, `vkQueueSubmit` returns `VK_ERROR_DEVICE_LOST`) in five runs, with warm and cold shader caches; without the variable the same dispatch runs. The device-fault report gives no instruction address the module maps to, so the cause is not attributed. Keeping a faulting invocation running in its spanned wave (`bdaStopsInvocations` off for spanned programs) and #6416 did not change it. Stray (PPSA02101) on Intel ANV and a Demon's Souls (PPSA01342) request replay showed no fault
+- [Spanned wave64 compute](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvSubgroup.cpp) (shader recompiler) - `APS5_SPANNED_WAVE=1`, off by default, runs a single-wave wave64 compute program at one lane per invocation on a 32-lane host subgroup and exchanges ballots, shuffles and reductions between the two host subgroups through workgroup memory and barriers. Those barriers are correct only where every invocation of the workgroup reaches them, which holds for the guest's wave-uniform control flow. The emulated 64-bit LDS atomics ([LockedLdsUpdate](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp)) run only on the lanes the exec mask keeps, so their lock loop ballots within its own host subgroup, as its elect already does. Any other cross-lane exchange emitted inside per-lane control flow would hang a spanned wave in the same way. In Ghost of Yōtei's program 0x80003af600 (PPSA26344), the lock loop was the only place where barriers sat inside per-invocation conditionals (3 of 111, found by scanning the SPIR-V). Other programs and titles have not been scanned. Measured on an RTX 4090 (Windows): an offline replay of that program and two Yōtei runs that previously lost the device (NVIDIA TDR) now run past it, and [LdsMaskWaterfall.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/LdsMaskWaterfall.cpp) covers a half-inactive wave. Stray (PPSA02101) on Intel ANV and a Demon's Souls (PPSA01342) request replay showed no fault, before this fix

+Registry `nid` fields may contain either encoded NIDs or ordinary ELF symbol names such as `strcmp`. Imports are matched against literal exports first, then against their computed NIDs when the literal lookup misses. Reports retain the original import name. Export availability does not establish that every platform loader supports that lookup path.

Subject: [PATCH 0499/1000] fix(agc): discard pipeline journals written before
 the mesh field

The layout guards only build on Linux with libstdc++, so a Windows or
macOS build of main after #5884 wrote journals whose mesh records lack
outputPrimitiveSize under the new shader-cache source version. The
journal format is now 3, so such a file is discarded instead of being
read with the new codec. MarcZX100 pointed this out.

Subject: [PATCH 0500/1000] feat(agc): write a multisampled color target
 through a storage image

A program that stores to a 2D multisampled texture writes the samples of
its host multisampled color target through a storage view. Targets are
created without storage usage; the first storage binding that resolves
to a target moves it to an image with storage usage, copying its samples
once, and keeps the previous image until the target is released. Storage
usage needs the device's shaderStorageImageMultisample feature and its
format at the target's sample count. A surface no draw rendered to is
created from its uniform color memory, as for sampling; other color
memory still throws.

Subject: [PATCH 0502/1000] feat(agc): carry spanned waves in the target and
 require full subgroups

APS5_SPANNED_WAVE is now read once by the driver, which sets
SpirvTarget::spannedWaves only on a device with 32-lane compute subgroup
control and computeFullSubgroups. The recompiler no longer reads the
environment. The field is part of the cache key and of the request
serialization (version 32), so a cached or replayed module keeps the mode
it was built in.

A spanned module numbers its lanes SubgroupId * 32 +
SubgroupLocalInvocationId, which needs two full 32-lane subgroups. The
artifact records this as fullSubgroups (disk cache and pipeline identity
included), and the driver creates those pipelines with
REQUIRE_FULL_SUBGROUPS. Compute pipeline captures accept the flag with a
required subgroup size.

The two-lane fallback now catches only SpannedWaveUnsupported, thrown for
a shuffle wider than 32 bits; other emit errors surface as before.

Subject: [PATCH 0503/1000] test(agc): run the LDS mask waterfall in both wave
 modes

The test set neither mode, so ctest ran only the two-lane form. It now
recompiles each program two-lane and then spanned through
SpirvTarget::spannedWaves, checks that the spanned module asks for full
subgroups, and skips the spanned pass on a device without full 32-lane
compute subgroups.

Not measured on hardware.
 - [Flag structurization](../../../core/shader/recompiler/ControlFlow/src/Structurizer.cpp) (shader recompiler) - a graph that every structurizer attempt refuses, irreducible and non-terminating graphs included, is rebuilt with one reach flag per block and one again flag per loop (`structurizeWithFlags`): each block keeps one copy and runs behind a guard on its flag, and each strongly connected component becomes a loop whose single latch repeats it while a back edge set its flag. The output has about 8 times the input's blocks and one route variable per block, and ends in an empty Return that never runs. Only blocks that start the top-level order unconditionally run unguarded, so resource planning also sees the static paths that skip a guarded block and can plan extra descriptor candidates for them. The attempts still run first. Shared merge splitting refuses an attempt once the graph has grown past 16 times its block count at the start of splitting (at least 64 blocks); succeeding attempts grew at most 10.6 times on random graphs of up to 128 blocks, and an attempt that would succeed only beyond the budget leaves the graph to a later attempt or to this construction. Splitting that adds one block per round stays within that budget until its 4 rounds per block run out, so the attempts can still take more than 10 s (9 of 2,000 random graphs of up to 128 blocks, 63 s at most). `APS5_FORCE_STRUCTURIZER_FALLBACK=1` builds every graph this way, for tests
 - [Scalar buffer descriptors](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) use only the base address, stride and record count for resources accessed exclusively by scalar loads; their fourth word is normalized to zero, following AMD RDNA2 ISA section 7.2.2. Vector and mixed accesses retain descriptor validation. Native Vulkan readbacks cover ignored fourth-word fields on Windows/NVIDIA; their console behavior has not been measured.
-- [Spanned wave64 compute](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvSubgroup.cpp) (shader recompiler) - `APS5_SPANNED_WAVE=1`, off by default, runs a single-wave wave64 compute program at one lane per invocation on a 32-lane host subgroup and exchanges ballots, shuffles and reductions between the two host subgroups through workgroup memory and barriers. Those barriers are correct only where every invocation of the workgroup reaches them, which holds for the guest's wave-uniform control flow. The emulated 64-bit LDS atomics ([LockedLdsUpdate](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp)) run only on the lanes the exec mask keeps, so their lock loop ballots within its own host subgroup, as its elect already does. Any other cross-lane exchange emitted inside per-lane control flow would hang a spanned wave in the same way. In Ghost of Yōtei's program 0x80003af600 (PPSA26344), the lock loop was the only place where barriers sat inside per-invocation conditionals (3 of 111, found by scanning the SPIR-V).

+- [Spanned wave64 compute](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvSubgroup.cpp) (shader recompiler) - `APS5_SPANNED_WAVE=1`, off by default, runs a single-wave wave64 compute program at one lane per invocation on a 32-lane host subgroup and exchanges ballots, shuffles and reductions between the two host subgroups through workgroup memory and barriers. The driver turns it on only where compute subgroups can be pinned at 32 full lanes (`subgroupSizeControl` and `computeFullSubgroups`), passes it as `SpirvTarget::spannedWaves` (part of the cache key and the serialized request), and creates the pipelines of spanned programs with `REQUIRE_FULL_SUBGROUPS`, since the lane number `SubgroupId * 32 + SubgroupLocalInvocationId` needs two full subgroups. Those barriers are correct only where every invocation of the workgroup reaches them, which holds for the guest's wave-uniform control flow. The emulated 64-bit LDS atomics ([LockedLdsUpdate](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp)) run only on the lanes the exec mask keeps, so their lock loop ballots within its own host subgroup, as its elect already does. Any other cross-lane exchange emitted inside per-lane control flow would hang a spanned wave in the same way, and the emitter does not reject one: there is no uniformity check. The only check so far is manual: disassemble the module (`spirv-dis`), list the selection and loop constructs that enclose each `OpControlBarrier`, and read the condition of each enclosing selection. In Ghost of Yōtei's program 0x80003af600 (PPSA26344), 108 of 111 barriers sat only in loops on wave-uniform conditions and 3 inside per-invocation conditionals, all in the lock loop. Other programs and titles have not been scanned. An earlier, cheaper ballot (one barrier instead of three) also lost the device for a reason that is not understood, which may be another barrier placement problem. Measured on an RTX 4090 (Windows): an offline replay of that program and two Yōtei runs that previously lost the device (NVIDIA TDR) now run past it, and [LdsMaskWaterfall.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/LdsMaskWaterfall.cpp) runs both modes and covers a half-inactive wave.

Subject: [PATCH 0505/1000] perf(agc): pre-sync the DCC key writers of a
 dispatch's images before the GPU mutex

The stage-A pre-sync of a dispatch listed only the surfaces that stage B reads on the CPU. The DCC
keys of an image that a recorded kernel writes were not in the list, so stage B waited for that
kernel in WaitForKeyWriters with the GPU mutex held and every other worker queued behind the wait.
At the Minecraft Dungeons II title the pre-sync fired once in 296,000 dispatch checks while
WaitForKeyWriters synchronized 400 times per 10 s.

PresyncSurfaces now also returns the key range of every image binding (PresyncSurface::dccKeys).
presync waits for a key range only while recorded work writes it, the key-store memo does not
already give its value (DccKeyWritersPending) and, under the mutex it takes for a moment anyway, the
pending stores do not give the keys either (DccKeyWriterNeedsSync, the test WaitForKeyWriters makes
before it synchronizes). Which keys the dispatch reads, and when, is unchanged: the locked lookup runs
as before and finds nothing pending.

APS5_NO_DCC_PRESYNC=1 leaves the key ranges out. The [presync] line counts key ranges checked,
pre-syncs that only the keys required and the outcomes of WaitForKeyWriters. The test
agc_driver_dcc_key_presync covers a kernel that writes the keys, a recorded fill of the keys and
nothing pending, and skips with the reasons check_skips.py expects when the device has no timeline
semaphores or no host import.

 - A compute shader whose LDS plus its lock dword exceeds the host's `maxComputeSharedMemorySize` is not given a `Workgroup` array. `Recompile` sets `ShaderInfo::sharedMemoryBytes` for it and the SPIR-V backend addresses the LDS in a coherent storage buffer at descriptor set 1 (`WorkgroupMemoryDescriptorSet`), with a slice of `RecompileResult::workgroupMemoryDwords` per workgroup, indexed by `WorkgroupID` and `NumWorkGroups`. `VulkanDevice` keeps one such buffer, sized from the dispatch dimensions, and binds it after the resource set; programs that fit keep using shared memory.
 - `Driver::RegisterShader` splits shader preparation in two. `PlanRegistered` runs on the registering guest thread: it validates the registers and entry point, decodes the code and builds the recompile request, so invalid registrations still fail there. The RDNA to IR translation and resource plan (`PrepareShader`) run on a background pool of `hardware_concurrency() / 2` detached threads (at least 2, 64 MiB stacks).
 - Queue 0's packet worker decodes, captures and prepares a draw and hands its recording (`Graphics::Draw` under the GPU lock) to a committer thread in [`DrawPipeline.cpp`](../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Draw/DrawPipeline.cpp), so the next packet is decoded while the previous draw is recorded. Each queued item carries the guest ranges it will write (`DrawWriteRanges`: written buffers and storage images, color targets with their DCC and CMASK, depth and stencil). A later packet that reads or writes one of those ranges, or that the pipeline can't order, drains it first; labels, submission ends, buffer fills and (with `APS5_PIPELINE_DMA=1`) DMA packets are queued as items instead. With `APS5_PIPELINE_DISPATCH=1` (off by default), a `DISPATCH_DIRECT` whose dispatch-cache entry hits with a recipe is queued as an item too, carrying the dispatch's written buffers and storage images (`DispatchWriteRanges`); the capture and the cache lookup stay on the worker and the recipe is recorded on the committer. A dispatch still drains when its lookup misses, when what it reads overlaps a write still pending, when the hit is verified against data or when its writes cannot be ranged (bindless access, GDS, fault buffer). An exception thrown by a commit is rethrown on the worker at its next enqueue or drain, as an inline draw error would be. On by default; `APS5_PIPELINED_DRAWS=0` records every draw inline, and `APS5_EXACT_DRAW_WRITES=0` widens the color and depth ranges to estimates.
+- A dispatch's resource build runs stage A (binding plan, buffers, descriptor set) without the GPU lock and stage B (image lookups) under it. Between them `VulkanDevice::presync` waits, still without the lock, for recorded work that writes a surface stage B would read on the CPU and for recorded work that writes the DCC keys of an image the dispatch binds (`ShaderResources::PresyncSurfaces`), so the locked `WaitForKeyWriters` finds nothing pending to synchronize with. A key range is waited for only when recorded work writes it, the key-store memo does not give its value (`DccKeyWritersPending`, without the mutex) and the pending stores do not give it either (`DccKeyWriterNeedsSync`, under the mutex, the same test `WaitForKeyWriters` makes before it synchronizes). Stage A's own key scan runs before that wait, and stage B compares it with the keys it reads under the lock as before. `APS5_NO_DCC_PRESYNC=1` leaves the key ranges out; `APS5_NO_PRESYNC=1` disables the whole pre-sync.
 - The shader registry maps a code address to every header registered for that code, in registration order. Static, graphics and rectangle ABI resolution pick the header at the bound address (or one equal to it, `SameHeader`, which also takes a hull header fused by `sceAgcFuseShaderHalves` (type 3) as the registered back half (type 7) it copies, the fused registers aside; graphics ABI resolution then uses the fused header's shader registers); draws and dispatches pick the program by the stage's binary type (`RegisteredProgram`), and a front entry matching both type 2 and type 4 throws. Within a type the last registration wins; re-registering an identical earlier header makes its snapshot current again without preparing it again, and changed code drops the older headers.
 - The snapshot is published as pending. `SourceHandleFor`, `InvocationFor` and `ShaderPreparationTransaction::Edit` / `Read` wait for the pending job before reading `PreparedShaders`, and rethrow its failure. `APS5_SYNC_SHADER_PREPARE=1` prepares on the registering thread instead.
 - `APS5_LAZY_SHADER_PREPARE=1` retains registration validation and decoding but discards the temporary plan without queueing preparation. The snapshot is deferred, not pending; draws and dispatches prepare and cache it on first use. Explicit ABI resolution still prepares its requested stages. This opt-in mode takes precedence over synchronous registration preparation and trades background CPU/memory use for possible first-use stalls; disk caches and shader output are unchanged.

Subject: [PATCH 0506/1000] perf(agc): spin before blocking on the GPU mutex
 and the draw committer hand-offs

At the Minecraft Dungeons II title the queue-0 worker, the draw committer and the compute worker
hand work to each other 49,000 times per 10 s through the GPU mutex, the committer's condition
variable and DrawPipeline::Drain, and each hand-off that has to wait costs a kernel wake-up. The
three workers are busy 21-34 % of the time: the GPU idles because the chain of hand-offs is slow,
not because a thread runs out of CPU.

GpuMutexType::lock retries try_lock for a window before it blocks, the committer polls its item
count for the window before it waits on its condition variable, and Drain polls for twice the
window before it waits for the committer. A hand-off that completes within the window costs no
wake-up. The window is 150 us on machines with at least 8 logical processors and 0 below that;
APS5_HANDOFF_SPIN_US sets it (0 turns it off). Ordering and the lock's semantics are unchanged.
The test agc_handoff_spin covers the window policy, the spin helpers and contended locks, and
docs/dev/ARCHITECTURE.md describes the spin.

 - The Vulkan pipelines are journaled as well ([`PipelineJournal.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/PipelineJournal.cpp)): a graphics pipeline the store builds (`CachedPipeline`) or a compute pipeline a dispatch builds is appended to `pipelines.journal` next to the shader cache entries, as the materialized result of each stage (the specialized SPIR-V, bindings and push constants, through `ShaderDiskCache::EncodeResult`) plus the recipe the pipeline was built from (`GraphicsPipelineRecipe`: the stages' identities, vertex input layout, descriptor set layout keys and the state fields the `Pipeline` constructor reads, `CanonicalPipelineState`). When a `VulkanDevice` is created, the journal is loaded and its pipelines are built on a pool of `hardware_concurrency() / 2` threads (`APS5_PIPELINE_JOURNAL_THREADS`) while the title loads, so the first draw or dispatch of a configuration seen on an earlier run finds its pipeline resident. The pipeline stores key on `RecompileResult::Identity`, a hash of the module words, specialization constants, subgroup width and bindings that is the same on every run (`SharedSpirv::ContentHash`, computed once per shared module), rather than on the process-lifetime variant ids, and a graphics pipeline is built outside the store's mutex, so the replay threads and the queue workers build in parallel. A draw that arrives before its replayed entry builds the pipeline itself; the first inserted wins. A replayed entry enters the store at its least recently used end and a full store takes none, so the title's own pipelines are never evicted for a replayed one, and the optimized relink of a replayed pipeline (`OptimizedPipeline::Schedule`) waits for the first draw that binds it, so the relink thread serves the title's pipelines first. A device created without a window starts its replay at its first draw or dispatch rather than at creation, since `Driver::AttachWindow` usually replaces it before the title draws. The journal records a pipeline once (modules and recipes are deduplicated by content), keeps at most `APS5_PIPELINE_JOURNAL_MAX_MIB` (1024), replays the first `APS5_PIPELINE_JOURNAL_ENTRIES` recorded (1024, the pipeline store's bound, `APS5_PIPELINE_STORE_ENTRIES`; a run reaches those first), and is disabled with `APS5_NO_PIPELINE_JOURNAL=1` or without a shader cache directory. The file header names the device (`PipelineJournalDeviceFingerprint`, the properties the driver's pipeline cache file is named by), so a journal written for another GPU or driver is started over rather than replayed; appends and reads hold `pipelines.journal.lock` against another process sharing the directory, and a device cancels its replay before it is replaced (`PrepareForReplacement`) or destroyed, so a replaced headless device never inserts entries the window's device then sweeps. `APS5_PROFILE_DRAW=1` prints a `[pipeline-journal]` summary when the replay finishes and at teardown.
 - A compute shader whose LDS plus its lock dword exceeds the host's `maxComputeSharedMemorySize` is not given a `Workgroup` array. `Recompile` sets `ShaderInfo::sharedMemoryBytes` for it and the SPIR-V backend addresses the LDS in a coherent storage buffer at descriptor set 1 (`WorkgroupMemoryDescriptorSet`), with a slice of `RecompileResult::workgroupMemoryDwords` per workgroup, indexed by `WorkgroupID` and `NumWorkGroups`. `VulkanDevice` keeps one such buffer, sized from the dispatch dimensions, and binds it after the resource set; programs that fit keep using shared memory.
 - `Driver::RegisterShader` splits shader preparation in two. `PlanRegistered` runs on the registering guest thread: it validates the registers and entry point, decodes the code and builds the recompile request, so invalid registrations still fail there. The RDNA to IR translation and resource plan (`PrepareShader`) run on a background pool of `hardware_concurrency() / 2` detached threads (at least 2, 64 MiB stacks).
+- A thread that needs the GPU mutex, the committer's next item or the end of the committer's queue spins before it blocks (`HandoffSpin.hpp`): `GpuMutexType::lock` retries `try_lock` for the window, the committer polls its item count, and `DrawPipeline::Drain` polls it for twice the window, so a hand-off that completes within the window costs no kernel wake-up. The window is 150 us on machines with at least 8 logical processors and 0 below that, where the spinning threads would compete with the holder; `APS5_HANDOFF_SPIN_US=<n>` sets it (0 turns it off, at most 10000). Ordering and the lock's semantics are unchanged.
 - Queue 0's packet worker decodes, captures and prepares a draw and hands its recording (`Graphics::Draw` under the GPU lock) to a committer thread in [`DrawPipeline.cpp`](../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Draw/DrawPipeline.cpp), so the next packet is decoded while the previous draw is recorded. Each queued item carries the guest ranges it will write (`DrawWriteRanges`: written buffers and storage images, color targets with their DCC and CMASK, depth and stencil). A later packet that reads or writes one of those ranges, or that the pipeline can't order, drains it first; labels, submission ends, buffer fills and (with `APS5_PIPELINE_DMA=1`) DMA packets are queued as items instead. With `APS5_PIPELINE_DISPATCH=1` (off by default), a `DISPATCH_DIRECT` whose dispatch-cache entry hits with a recipe is queued as an item too, carrying the dispatch's written buffers and storage images (`DispatchWriteRanges`); the capture and the cache lookup stay on the worker and the recipe is recorded on the committer. A dispatch still drains when its lookup misses, when what it reads overlaps a write still pending, when the hit is verified against data or when its writes cannot be ranged (bindless access, GDS, fault buffer). An exception thrown by a commit is rethrown on the worker at its next enqueue or drain, as an inline draw error would be. On by default; `APS5_PIPELINED_DRAWS=0` records every draw inline, and `APS5_EXACT_DRAW_WRITES=0` widens the color and depth ranges to estimates.
 - The shader registry maps a code address to every header registered for that code, in registration order. Static, graphics and rectangle ABI resolution pick the header at the bound address (or one equal to it, `SameHeader`, which also takes a hull header fused by `sceAgcFuseShaderHalves` (type 3) as the registered back half (type 7) it copies, the fused registers aside; graphics ABI resolution then uses the fused header's shader registers); draws and dispatches pick the program by the stage's binary type (`RegisteredProgram`), and a front entry matching both type 2 and type 4 throws. Within a type the last registration wins; re-registering an identical earlier header makes its snapshot current again without preparing it again, and changed code drops the older headers.
 - The snapshot is published as pending. `SourceHandleFor`, `InvocationFor` and `ShaderPreparationTransaction::Edit` / `Read` wait for the pending job before reading `PreparedShaders`, and rethrow its failure. `APS5_SYNC_SHADER_PREPARE=1` prepares on the registering thread instead.

Subject: [PATCH 0507/1000] fix(agc): bound the async log's exit flush

On Windows the atexit handlers of a DLL run after the process has ended
its other threads, so the logger thread can be gone with lines still
queued and the unbounded Flush waits forever (guest_shader_link timed
out on 4 of the last 7 completed main builds since #6371). Run the bounded
FlushAtEnd there instead.

 - **Queue.** One logger thread drains a queue that holds at most 16 MiB of waiting lines; the batch the logger is writing comes on top. A caller that finds the queue full blocks until the logger has taken the pending batch, so no line is dropped. The logger writes entries in queue order and joins consecutive entries of one stream; it writes them with one `fwrite` and flush when the text reaches 64 KiB, the stream changes or the batch ends. `AGC_LOG_DEFERRED` queues the format string with numeric, enum and `LogLiteral` arguments and formats them on the logger thread; `APS5_LOG_TIMESTAMPS` stamps a line when it is queued.
 - **Order.** Lines that pass through the sink, on stdout and stderr alike, appear in call order. A direct `fprintf(stderr, ...)` or `printf` does not pass through it and is written at once, so it can appear before older queued lines; the coalesced `deferred write-back failed` notes are of this kind. `APS5_LOG_SYNC=1` keeps one order for all of them.
-- **Flush.** `Flush` waits without a limit until every line queued before the call has been written, including while another thread holds the stream. It runs when the driver fails, in `Driver::stop` and at exit. `AsyncLog` also registers a bounded flush (`FlushFor`, 2 s) with `LibcSetEndFlush_nid_no_patch`; libc runs it where the process ends without those: `abort()` and `std::terminate` (a `SIGABRT` handler that the first registration chains in front of the previous one, so `raise(SIGABRT)` still ends the process), guest `abort()`, the Windows crash report of a fatal exception and guest `_Exit`. A title that installs its own `SIGABRT` disposition replaces that handler. The bounded flush polls two counters and takes no lock, so a thread that dies holding the queue lock or a stream cannot stall it. After 2 s it gives up, later calls return at once, and the lines still queued are lost.

At exit `AsyncLog` runs a bounded flush (`FlushFor`, 2 s) instead: on Windows the `atexit` handlers of a DLL run after the process has ended its other threads, so the logger thread may be gone with lines still queued, and a `Flush` there would wait forever. It also registers that bounded flush with `LibcSetEndFlush_nid_no_patch`; libc runs it where the process ends without `atexit`: `abort()` and `std::terminate` (a `SIGABRT` handler that the first registration chains in front of the previous one, so `raise(SIGABRT)` still ends the process), guest `abort()`, the Windows crash report of a fatal exception and guest `_Exit`.

After 2 s it gives up, later calls return at once, and the lines still queued are lost.
 - **Statistics.** A `[log]` line every 10 s in which lines were logged reports lines, bytes, the time spent by the callers and by the logger, and the queue peak; `APS5_LOG_STATS=0` hides it. Identical `deferred write-back failed` notes print three times per 10 s and are then counted in one `repeated N more times` line.
 
 `agc_async_log` checks the order of deferred and written lines, long lines, the repeat limit, a `Flush` that waits for a held stream, a bounded flush that gives up, and a full queue that blocks its caller. `agc_async_log_fatal` starts the test executable as a child that queues lines behind a held stream and then calls `abort()`, calls `std::terminate()`, raises an access violation (Windows) or `SIGABRT` (elsewhere), or aborts without ever releasing the stream; the first four must leave every line in the file in order, the last must still end after the bound.

Subject: [PATCH 0510/1000] test(ssl): run four connections on one context in
 parallel

Each client thread handshakes, writes, reads the reply and the end of
the stream, so session setup and record allocations from several
threads contend for the same context pool. The pool memory must return
to its loaded size afterwards.

Initialize the pool's mutex explicitly, which -Wextra asks for.

Subject: [PATCH 0511/1000] refactor(libkernel): share the Windows pipe query
 between poll and kevent

PipeReadiness and PipeReadState both opened the pipe handle and asked
NtQueryInformationFile for its access mask and local information. Both
now go through QueryPipe, which keeps each caller's error prefix.

Subject: [PATCH 0513/1000] test(agc): retry a settled import's first use when
 its copies finish first

The first-use check needs the main-queue copies of an import to be still in flight when the import returns to the write watch. On a fast device they can finish first, and the test then failed although the driver did nothing wrong. Retry with 4 and 16 times as many copies, and report the case as not tested when the copies finish first every time.

Subject: [PATCH 0519/1000] fix(agc): flush the async log within its exit bound
 when the driver stops

The driver's static is destroyed from its DLL's atexit table at process exit, after ExitProcess has ended the async log's worker. Its stop() then flushed the log through Flush(), which takes the log's lock and waits for every queued line, so it never returned when the worker died holding that lock or with lines queued. #6800's bounded flush runs after it, because the log registers it while the driver is being constructed. stop() now uses that bounded flush, which reads the counters without the lock and gives up after EndFlushLimit, marking the log abandoned. A new shutdown test mode holds the log's lock from another thread and checks that the driver's shutdown still returns.

 - [Host CPU check](../../../core/libs/prx/libkernel/System/src/HostCpu.cpp) (libkernel) - when libkernel loads on a Linux or Windows x86-64 host, it logs which of the PS5 CPU's user-mode extensions CPUID reports and throws, naming the host CPU, if any extension is missing that LLVM selects from plain C/C++ for the PS5's Zen 2 (`-march=znver2`, [feature list](https://github.com/llvm/llvm-project/blob/llvmorg-19.1.7/llvm/lib/Target/X86/X86.td#L1459-L1513)): SSE to SSE4.2, SSSE3, POPCNT, LZCNT, BMI1, BMI2, MOVBE, CMPXCHG16B, LAHF/SAHF, AVX, AVX2, FMA, F16C, and the operating system's AVX state in XCR0 (#3719). SSE4A, CLZERO and SHA, which `--to-intel` converts, and AES, PCLMULQDQ, RDRAND, RDSEED, ADX, CLFLUSHOPT, CLWB, RDPID, XSAVEOPT, XSAVEC and PREFETCHW, which compilers emit only for intrinsics or explicit prefetches, are logged but not required: a title that executes one of them on a host without it still stops with an illegal instruction. macOS hosts are not checked: some Rosetta versions execute extensions without reporting them through CPUID, but support differs by host. ANDN and RDRAND fault on an M1 with macOS 15.3.1; see the [Rosetta conversion limits](relinker.md)
 - [machdep.tsc_freq](../../../core/libs/prx/libkernel/System/src/SystemConfiguration.cpp) (libkernel) reports the host TSC frequency that `sceKernelGetTscFrequency` measures, as a 64-bit value like FreeBSD 11's [`sysctl_machdep_tsc_freq`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/x86/x86/tsc.c#L658-L676). FreeBSD lets root write it to change the TSC timecounter's frequency; a write here returns -1 with `EPERM`.

The console's limit is not known; XPSemu (PPSA97358) reads it in QEMU's `os_setup_limits` and raises the soft limit to the hard one when they differ. `RLIMIT_STACK`, `RLIMIT_RSS`, `RLIMIT_MEMLOCK` and `RLIMIT_NPROC` throw because no console values are established.

Java 25 LAN / DNS (PPSA99869) sets `rlim_cur = MIN(0x100000, rlim_max)` during VM initialization

 - [socketpair](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) - the pair is the host's `AF_UNIX` pair on Linux and, on Windows, a loopback TCP connection for `SOCK_STREAM` or two connected UDP sockets for `SOCK_DGRAM`; `SOCK_SEQPACKET` throws on Windows. A datagram sent to a full receiver gets `ENOBUFS` on the console, waits or gets `EAGAIN` on Linux and is dropped on Windows, and on Windows a datagram `recv` after the peer closed reports `ECONNRESET` instead of the console's `ENOTCONN`, and a stream `send` after the peer closed reports `ECONNABORTED` instead of the console's `EPIPE`. `read` and `write` on a pair end go to the host like on every guest socket. `getpeername` on a pair end succeeds after the peer closed, where the console returns `ENOTCONN`, and `connect`, `bind` and `sendto` with an address on a pair end report an address-family error instead of the console's `EISCONN`. On Windows `poll` on a stream end reports `POLLHUP` without `POLLIN` after the peer's `shutdown(SHUT_WR)` or `close`, where the console reports `POLLIN`, with `POLLHUP` only after `close`
 - [UDP recv/recvfrom](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) and [sceNetRecv/sceNetRecvfrom](../../../core/libs/prx/libSceNet/Export.cpp) translate Windows WSAEMSGSIZE into the copied byte count for datagram sockets, including MSG_PEEK, and retain the sender address. This follows FreeBSD 11.4 recv(2) and Winsock's documented truncated-datagram behavior; console behavior and existing title impact are unverified.

Subject: [PATCH 0521/1000] fix(build): link the fixed-base loader test with
 ld.bfd

wild 0.10.0 gives no canonical PLT entry to a DSO function whose address a
non-PIE executable takes (wild-linker/wild#2469, fixed after the release by
#2480), so the absolute personality pointer in .eh_frame names a local stub
and every exception reaching main is unhandled.

 Besides the recompiled shaders, the shader cache directory holds `pipelines.journal`: every Vulkan graphics pipeline the pipeline store kept and every compute pipeline a run built, with the specialized shader modules they were built from. The next run of the title builds those pipelines on background threads while it loads, so a draw or dispatch the earlier run already made does not compile its pipeline when it is first reached. The journal belongs to the GPU and driver that wrote it, like the driver's pipeline cache file next to it: a run on another GPU or driver version starts it over, and the driver's own pipeline cache decides how fast each pipeline is rebuilt. Two runs sharing the directory take turns on `pipelines.journal.lock`; a run that cannot lock it records nothing. `APS5_NO_PIPELINE_JOURNAL=1` disables recording and replay; `APS5_PIPELINE_JOURNAL_THREADS` sets the replay threads (half the CPU threads by default; `0` records without replaying), `APS5_PIPELINE_JOURNAL_ENTRIES` how many pipelines are replayed (the first recorded, which a run reaches first) and `APS5_PIPELINE_STORE_ENTRIES` how many graphics pipelines stay resident (1024 each), and `APS5_PIPELINE_JOURNAL_MAX_MIB` (1024) the file size at which recording stops. Deleting the file loses nothing but the head start. With `APS5_PROFILE_DRAW=1` a `[pipeline-journal]` line reports what was loaded, replayed and recorded.
 
+### Texture cache budget
+
+Sampled textures and storage images stay in device memory in two caches that evict their least recently used entries when they grow past their budgets. The storage image budget is a quarter of the `VK_EXT_memory_budget` budget of the largest device-local heap, capped at a quarter of the heap's size or 2 GiB, whichever is larger, and never below 512 MiB. The sampled texture budget is what the reported budget leaves after the heap's use other than cached textures, that cap and an eighth of the budget, and never below 2 GiB. Both are read again every second; `[gpu] sampled texture cache budget` lines report them at start-up and when they change. `APS5_TEXTURE_CACHE_MIB=<n>` fixes both budgets at `n` MiB, and the lines are then not printed.
+
+A fixed budget above the automatic one can exceed what the card holds next to the rest of the frame. Allocations then go to host memory (`[gpu] ... placed in host memory` lines), where the GPU reads them over PCIe. PPSA16064 on an RTX 4060 8 GB, whose automatic storage image budget is 1797 MiB, placed 868 and 878 MiB in host memory with `APS5_TEXTURE_CACHE_MIB=3072` and walked through its first level at 4.46 and 4.83 FPS; with the variable unset it placed none and ran the same walk at 6.48 and 6.07 FPS. Leave it unset unless a measurement on the card shows otherwise.
+
 ### Storing GPU results at each flip
 
 GPU results in storage images and render targets stay on the GPU until something reads their memory. A title that frees such an image after waiting for its GPU work and reuses the memory can have its new data overwritten when the results are stored later ([TechnicalDebt](../dev/TechnicalDebt.md)). `APS5_STORE_AT_FLIP=1` stores every pending result when a display buffer is flipped, at the cost of one write-back per pending image and frame. Any other value stops the title at its first flip.

 With `APS5_TRACE_SUMMARY_EVERY` set, the recorder writes a timestamp pair per batch for the whole run and every `PerformanceTimer` scope adds its time to the thread's totals, two clock reads per scope. A thread's totals are read while it runs, so a scope that straddles an interval boundary is counted in one interval or the other.
 
+## GPU time per command class
+
+Set `APS5_PROFILE_GPU=1` (any value) to time the recorder's GPU work with timestamp queries and print one `[gputime]` line on stderr. `APS5_PROFILE_DRAW` alone does not print it: a batch then gets only its whole-batch timestamp pair. A timed range is a pair of bottom-of-pipe stamps that both wait for all earlier work, so a range is the time its own work adds after everything recorded before it. A batch holds at most 512 ranges, its whole-batch range included. The line is written when a batch's timestamps are read after its fence, at least 10 s after the previous line, and covers every batch read since then.
+
+The header fields: `<n> ms of GPU time` is the sum of the program-keyed ranges only (dispatches and buffer copies, see `by program`); draws and the driver's own commands are not in it. `in <n> batches` counts the batches read. `batch <n> ms first to last command` sums the whole-batch ranges, from the stamp written when the batch opens (it waits for the batches before it) to the stamp written at `Submit`. `classes <n> ms` is the plain sum of every class range, including `present-blit`, which runs outside the batches. `all ranges <n> ms` is, per batch, the union of its class and program ranges, with overlapping time counted once; `present-blit` is not in it. `untimed <n> ms` is `batch` minus `all ranges`: batch time that no range covers, including the work of dropped ranges. `<n> presents` counts the `VulkanDevice::present` calls since the previous line. `<n> ranges dropped at the 512 cap` counts ranges refused because their batch was full.
+
+A class range covers a command together with its own barriers. In `VulkanDevice::CopyBuffer` the `copy` class range spans the leading barrier, the transfer and the trailing barrier, and the program-keyed range sits inside it around the transfer alone, so the transfer counts in both `GPU time` and `classes` but once in `all ranges`. A dispatch's leading and trailing barriers are ranges of their own classes, placed before and after its program range, not around it. `GPU time` plus `classes` can therefore exceed `batch`; compare `all ranges` with `batch` instead.
+
+`by program` lists up to 12 keys, highest time first, as `0x<key> x<ranges> <ms>ms`. A dispatch's key is its guest program address, or the program's `variantId` when the address is 0. A buffer copy's key is the program address of the copy kernel it replaces, or 0 for a PM4 DMA copy (opcode 0x50). `by class` lists every class with at least one range since the previous line as `<name> x<ranges> <ms>ms <MiB>MiB (per present x<ranges> <ms>ms <MiB>MiB)`; the per-present figures are 0 when there was no present. MiB is the byte count each range passes to `EndGpuTiming`. The classes, with the function that opens each range:
+
+- `dispatch-lead`: a dispatch's leading barrier, when it is recorded rather than merged into the previous trailing barrier (`VulkanDevice::recordDispatch`). 0 MiB.
+- `dispatch-trail`: a dispatch's trailing barrier (`recordDispatch`). 0 MiB.
+- `indirect-args`: the barrier that makes an indirect dispatch's host-imported group counts visible to the indirect read (`recordDispatch`). 12 bytes per range.
+- `label-run`: a run of GPU label stores (`vkCmdUpdateBuffer`, plus the queued occlusion dump folds of a per-batch run) with its barriers (`Recorder::RecordStore` for inline runs, `Recorder::closeStoreRun` for per-batch runs). Stored bytes.
+- `fill`: a guest fill of host-imported memory, as `vkCmdFillBuffer` or pattern copies, with its barriers (`VulkanDevice::FillBuffer`). Filled bytes.
+- `fill-clear`: a fill done as a `vkCmdClearColorImage` of a storage image, between two layout barriers (`StorageTexture::FillClear`). Filled bytes.
+- `copy`: the buffer copy of `VulkanDevice::CopyBuffer`, a whole-surface image copy (`StorageTexture::CopyFrom`) and the depth plane copies to and from storage images through a staging buffer (`copyPlane` and the layered copy in `DepthSurface.cpp`). Copied bytes.
+- `staging-in`: a build's copies of guest buffer regions into staging or host-copy buffers, between two barriers (`GuestBufferMemory::recordGpuCopies`). Copied bytes.
+- `staging-out`: the copies of shader-written sub-ranges back into the import (`GuestBufferMemory::RecordCopyBacks`). Copied bytes.
+- `draw`: for a lean draw, from its first barrier to the end of its render pass, so draws that continue the pass fall inside one range (`recordDraw`, ended by `Recorder::endOpenRenderPass`); for a recorded draw with layout transitions, from its first barrier to its download barrier (`Draw`). 0 MiB.
+- `storage-upload`: detiles of guest bytes into a storage image, whole (`StorageTexture::upload`) or by changed runs (`StorageTexture::uploadWindows`), and pending units copied from an alias image (`StorageTexture::borrowUnits`). Uploaded bytes.
+- `storage-writeback`: retiles of a storage image back to guest memory, by windows (`StorageTexture::writeBackWindows`) or by layers (`StorageTexture::writeBackLayers`). Stored bytes.
+- `dcc-clear`: a `vkCmdClearColorImage` of a storage image whose DCC keys read as a clear, at upload (`StorageTexture::upload`) or for a fill of its key bytes (`StorageTexture::clearByKeysFill`, with `APS5_KEYS_FILL_CLEAR=1`). Surface bytes.
+- `dcc-keys`: queued DCC key stores, as `0xff` fills and seed copies between two barriers (`Recorder::recordKeyStores`). Key bytes.
+- `present-blit`: the presentation command buffer from its first to its last command, timed in its own two-query pool (`VulkanDevice::present`) and added when its slot retires (`Recorder::AddGpuTiming`). Width x height x 4 bytes of the swapchain extent.
+- `shadow-publish`: copies of unit shadow slabs into the import, with their barriers (`recordCopies` in `UnitShadow.cpp`, reached from `PublishShadow`). Copied bytes.
+- `template-refresh`: the `vkCmdUpdateBuffer` updates of a cached dispatch's changed data words, as one range from the first update to the last (`ShaderResources::refreshData`, called from `recordDispatch`). Refreshed bytes.
+
 ## Driver thread priority
 
 Set `APS5_THREAD_PRIORITY=high` to raise the AGC driver's queue workers and the video output presenter above the title's threads. On Linux the threads get nice `APS5_THREAD_NICE` (default -10) through rtkit; on Windows they get `THREAD_PRIORITY_HIGHEST`. `APS5_THREAD_PRIORITY=rt` asks rtkit for real-time priority `APS5_THREAD_RT` (default 10, at most rtkit's `MaxRealtimePriority`) under rtkit's policy, `SCHED_RR` by default; on Windows it sets `THREAD_PRIORITY_TIME_CRITICAL`. rtkit only grants it when the process's hard `RLIMIT_RTTIME` is at most its `RTTimeUSecMax` (200000 us by default), so a hard limit above `APS5_THREAD_RTTIME_US` (default 200000, capped at `RTTimeUSecMax`) is lowered to it and the soft limit to at most half of it. The hard limit cannot be raised again and stays lowered for the whole process even if rtkit then refuses; see [technical debt](TechnicalDebt.md#functional). There is no fallback between the modes: when rtkit or `SetThreadPriority` refuses, a queue worker reports the refusal as a driver failure, which the next submission, wait or shutdown rethrows, and the presenter's start throws it. Each raised thread logs its priority once as `[thread-priority]`. The setting is `off` by default; a value other than `off`, `high` or `rt` is reported the same way as a refusal.

Subject: [PATCH 0527/1000] fix(agc): initialize the async log's condition
 variables before its worker starts

A condition variable that winpthreads initializes statically is set up on its first wait, under one global spinlock for all such variables. The async log's worker made that first wait itself, right after the driver started it, so a process that exited soon after starting the driver, such as guest_shader_link, could end with ExitProcess killing the worker inside that setup. The spinlock then stayed held, and the next destructor of a never-used condition variable, in ~Driver, spun forever. The log's constructor now waits on each of its condition variables once with no timeout before it starts the worker, so the worker's waits never take that spinlock. A new shutdown test mode exits right after the driver starts.

Subject: [PATCH 0531/1000] test(agc): bound the cancelled journal replay from
 its own start

The cancelled replay's bound was taken from the totals before the torn-tail replay, which already
adds one present pipeline; when a worker reached the graphics recipe before the cancel, the test
failed (13 of 600 runs with 24 in parallel).

Not confirmed on a console, and neither title starts on `main` yet. Parameter 400 returns the same number as parameter 1: PPSA01325 asks for 400 first, asks for 1 when that fails, and uses either answer as an index into the same 31 languages; in the PS5 10.01 and 12.60 `libSceSystemService` modules parameter 400 reads the same registry value as parameter 1, without parameter 1's mapping of newer language numbers by SDK version, and returns 0x80a10003 when an imported check that is not identified returns 1; the 4.03 module has no parameter 400. Neither the mapping nor that error is modelled, and the parameter's name is not known. Without `ANYPS5_LANGUAGE` the language is English (United States); the date format, time format, time zone, summer time and enter button stay fixed

Subject: [PATCH 0535/1000] ci: build and run only the tests a change reaches
 on request

A new select input of the Build workflow limits the Linux and Windows jobs
to the test executables and tests whose build inputs the merged pull
requests change. Push builds of main always build and run everything and
save the test graph of their tree; dispatched runs with select restore the
latest graph and fall back to a full run without one.

tools/select_tests.py dump walks the ninja graph of every test executable
(order-only dependencies included, so prx libraries loaded at run time are
in it) plus the header dependencies of its objects, the CMake files that
register each test, the source files its command line names, and its
fixtures. select picks the tests whose closure, registration or arguments
contain a changed file, and every test that is not a native executable of
the tree; files no build reads select the tests under their directory;
changes to the root build, cmake/, 3rdparty/, the workflow or the tool run
everything. Tests added since the graph was written always run. ctest gets
the selection as -I indices through the tool, which keeps the cmd shell on
Windows and stays under its command line limit.

Subject: [PATCH 0536/1000] ci: let a push to main cancel the build of the
 previous one

Push builds of main ran one after another, so a merge waited for the
builds of every earlier merge before main got a result for its tree; a
fix of a red main sat behind a build of the tree it fixes. The newest
push now cancels the build in progress, like pull request and dispatched
builds already do. The merge queue's baselines already skip cancelled
main builds and use the nearest completed ones.

+AnyPS5 relinks PS5 executables into native Linux or Windows programs that run against reimplemented system libraries; it is not an emulator. The rules are [CONTRIBUTING.md](CONTRIBUTING.md) and [CONVENTIONS](docs/dev/CONVENTIONS.md); these are the ones agents break.
+
+- No comments in code, except `#endif` and namespace ends.
+- An export you cannot implement calls `NotImplemented_nid_no_patch(__func__)`; never return a made-up success.
+- Implement the function for every input. Never special-case a value, ID or path seen in one title's trace; if the general behaviour is unknown, throw and record it in `docs/dev/debt/<library>.md`.
+- New third-party code is a submodule at `3rdparty/<name>`: add its `.gitmodules` entry (`git submodule add <url> 3rdparty/<name>`) and build it from source with CMake. Never `find_package` or copy sources in.
+- Known gaps go in `docs/dev/debt/<library>.md`; notes, reports and logs go in the pull request. Add no other files.
+- Commit subjects and PR titles are Conventional Commits.
+- PR body: copy [the template](.github/pull_request_template.md), keep every line, tick every box, and fill `What`, `Tested`, `Depends on` (#N or none), `Unblocks` (title ID and discussion, or none), `GPUs tested` (AGC, shader recompiler, VideoOut; otherwise n/a) and `AI-assisted` (yes or no).
+- Before pushing run `python3 tools/check_conventions.py --base origin/main`; before opening run `python3 tools/pr_overlap.py --branch <branch>`.
+- Build and test: [BUILD](docs/dev/BUILD.md); a relinker-only change builds with `-DANYPS5_RELINKER_ONLY=ON`.
+- A speed claim shows `tools/trace_digest.py` summaries of `main` and of the change from the same machine and scene.

Subject: [PATCH 0540/1000] perf(agc): count the processors the process may run
 on for the hand-off spin guard

The automatic window needed 8 logical processors, which a 4-core CPU with SMT passes while the waited-for thread may run on a sibling thread, and ignored the process affinity. It now needs more than 8 processors in the affinity mask (CpuTopology), falling back to hardware_concurrency.

 - The Vulkan pipelines are journaled as well ([`PipelineJournal.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/PipelineJournal.cpp)): a graphics pipeline the store builds (`CachedPipeline`) or a compute pipeline a dispatch builds is appended to `pipelines.journal` next to the shader cache entries, as the materialized result of each stage (the specialized SPIR-V, bindings and push constants, through `ShaderDiskCache::EncodeResult`) plus the recipe the pipeline was built from (`GraphicsPipelineRecipe`: the stages' identities, vertex input layout, descriptor set layout keys and the state fields the `Pipeline` constructor reads, `CanonicalPipelineState`). When a `VulkanDevice` is created, the journal is loaded and its pipelines are built on a pool of `hardware_concurrency() / 2` threads (`APS5_PIPELINE_JOURNAL_THREADS`) while the title loads, so the first draw or dispatch of a configuration seen on an earlier run finds its pipeline resident. The pipeline stores key on `RecompileResult::Identity`, a hash of the module words, specialization constants, subgroup width and bindings that is the same on every run (`SharedSpirv::ContentHash`, computed once per shared module), rather than on the process-lifetime variant ids, and a graphics pipeline is built outside the store's mutex, so the replay threads and the queue workers build in parallel. A draw that arrives before its replayed entry builds the pipeline itself; the first inserted wins. A replayed entry enters the store at its least recently used end and a full store takes none, so the title's own pipelines are never evicted for a replayed one, and the optimized relink of a replayed pipeline (`OptimizedPipeline::Schedule`) waits for the first draw that binds it, so the relink thread serves the title's pipelines first. A device created without a window starts its replay at its first draw or dispatch rather than at creation, since `Driver::AttachWindow` usually replaces it before the title draws. The journal records a pipeline once (modules and recipes are deduplicated by content), keeps at most `APS5_PIPELINE_JOURNAL_MAX_MIB` (1024), replays the first `APS5_PIPELINE_JOURNAL_ENTRIES` recorded (1024, the pipeline store's bound, `APS5_PIPELINE_STORE_ENTRIES`; a run reaches those first), and is disabled with `APS5_NO_PIPELINE_JOURNAL=1` or without a shader cache directory. The file header names the device (`PipelineJournalDeviceFingerprint`, the properties the driver's pipeline cache file is named by), so a journal written for another GPU or driver is started over rather than replayed; appends and reads hold `pipelines.journal.lock` against another process sharing the directory, and a device cancels its replay before it is replaced (`PrepareForReplacement`) or destroyed, so a replaced headless device never inserts entries the window's device then sweeps. `APS5_PROFILE_DRAW=1` prints a `[pipeline-journal]` summary when the replay finishes and at teardown.
 - A compute shader whose LDS plus its lock dword exceeds the host's `maxComputeSharedMemorySize` is not given a `Workgroup` array. `Recompile` sets `ShaderInfo::sharedMemoryBytes` for it and the SPIR-V backend addresses the LDS in a coherent storage buffer at descriptor set 1 (`WorkgroupMemoryDescriptorSet`), with a slice of `RecompileResult::workgroupMemoryDwords` per workgroup, indexed by `WorkgroupID` and `NumWorkGroups`. `VulkanDevice` keeps one such buffer, sized from the dispatch dimensions, and binds it after the resource set; programs that fit keep using shared memory.
 - `Driver::RegisterShader` splits shader preparation in two. `PlanRegistered` runs on the registering guest thread: it validates the registers and entry point, decodes the code and builds the recompile request, so invalid registrations still fail there. The RDNA to IR translation and resource plan (`PrepareShader`) run on a background pool of `hardware_concurrency() / 2` detached threads (at least 2, 64 MiB stacks).
-- A thread that needs the GPU mutex, the committer's next item or the end of the committer's queue spins before it blocks (`HandoffSpin.hpp`): `GpuMutexType::lock` retries `try_lock` for the window, the committer polls its item count, and `DrawPipeline::Drain` polls it for twice the window, so a hand-off that completes within the window costs no kernel wake-up. The window is 150 us on machines with at least 8 logical processors and 0 below that, where the spinning threads would compete with the holder; `APS5_HANDOFF_SPIN_US=<n>` sets it (0 turns it off, at most 10000). Ordering and the lock's semantics are unchanged.
+- A thread that needs the GPU mutex, the committer's next item or the end of the committer's queue spins before it blocks (`HandoffSpin.hpp`): `GpuMutexType::lock` retries `try_lock` for the window, the committer polls its item count, and `DrawPipeline::Drain` polls it for twice the window, so a hand-off that completes within the window costs no kernel wake-up. The window is 150 us when the process may run on more than 8 logical processors (its affinity mask, via `CpuTopology`) and 0 otherwise, where the spinning threads would compete with the holder; `APS5_HANDOFF_SPIN_US=<n>` sets it (0 turns it off, at most 10000). Ordering and the lock's semantics are unchanged.
 - Queue 0's packet worker decodes, captures and prepares a draw and hands its recording (`Graphics::Draw` under the GPU lock) to a committer thread in [`DrawPipeline.cpp`](../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Draw/DrawPipeline.cpp), so the next packet is decoded while the previous draw is recorded. Each queued item carries the guest ranges it will write (`DrawWriteRanges`: written buffers and storage images, color targets with their DCC and CMASK, depth and stencil). A later packet that reads or writes one of those ranges, or that the pipeline can't order, drains it first; labels, submission ends, buffer fills and (with `APS5_PIPELINE_DMA=1`) DMA packets are queued as items instead. With `APS5_PIPELINE_DISPATCH=1` (off by default), a `DISPATCH_DIRECT` whose dispatch-cache entry hits with a recipe is queued as an item too, carrying the dispatch's written buffers and storage images (`DispatchWriteRanges`); the capture and the cache lookup stay on the worker and the recipe is recorded on the committer. A dispatch still drains when its lookup misses, when what it reads overlaps a write still pending, when the hit is verified against data or when its writes cannot be ranged (bindless access, GDS, fault buffer). An exception thrown by a commit is rethrown on the worker at its next enqueue or drain, as an inline draw error would be. On by default; `APS5_PIPELINED_DRAWS=0` records every draw inline, and `APS5_EXACT_DRAW_WRITES=0` widens the color and depth ranges to estimates.
 - The shader registry maps a code address to every header registered for that code, in registration order. Static, graphics and rectangle ABI resolution pick the header at the bound address (or one equal to it, `SameHeader`, which also takes a hull header fused by `sceAgcFuseShaderHalves` (type 3) as the registered back half (type 7) it copies, the fused registers aside; graphics ABI resolution then uses the fused header's shader registers); draws and dispatches pick the program by the stage's binary type (`RegisteredProgram`), and a front entry matching both type 2 and type 4 throws. Within a type the last registration wins; re-registering an identical earlier header makes its snapshot current again without preparing it again, and changed code drops the older headers.
 - The snapshot is published as pending. `SourceHandleFor`, `InvocationFor` and `ShaderPreparationTransaction::Edit` / `Read` wait for the pending job before reading `PreparedShaders`, and rethrow its failure. `APS5_SYNC_SHADER_PREPARE=1` prepares on the registering thread instead.

Subject: [PATCH 0542/1000] feat(libc): read app0.zar beside app0 and refuse
 archive-only paths elsewhere

A ZArchive named app0.zar beside app0/ is a read-only layer under it. libc opens it at the first path resolution, looks paths missing from app0/ up case-insensitively, reads files across compressed blocks and keeps the archived descriptor table with shared positions.

Resolving an archive-only path through a call that does not read the archive throws instead of failing with ENOENT, as do opendir of a directory present in both places, fdopen of an archived descriptor and chdir into the archive. A path through .. in an archive-only directory resolves.

 - [std::_Throw_Cpp_error](../../../core/libs/prx/libc/src/exception/StandardExceptions.cpp) (libSceAmpr) follows Dinkumware's `thread0.cpp` as shipped with [Visual C++ 2013](https://github.com/ganboing/crt.vc12/blob/f1d47126bf13d1c9dccaa6c53b72217fd0474968/src/thread0.cpp) and in [microsoft/STL](https://github.com/microsoft/STL/blob/da52dc0fcadbd83690cfd1ed32408d2847439493/stl/src/thread0.cpp), without console verification. `_Cpp_error` codes 0 to 6 throw a guest `std::system_error` whose `error_code` holds the FreeBSD errno of the `errc` value (EBUSY 16, EINVAL 22, ESRCH 3, ENOMEM 12, EPERM 1, EDEADLK 11, EAGAIN 35) and the generic category, and whose `what()` is the table message, `": "` and the generic category's message for that errno, selected by the first matching errno entry in VC12's [`syserror.cpp`](https://github.com/ganboing/crt.vc12/blob/f1d47126bf13d1c9dccaa6c53b72217fd0474968/src/syserror.cpp); another code throws `std::out_of_range` on the host instead of reading past the table. The guest `system_error` is taken to be [VC12's](https://github.com/ganboing/crt.vc12/blob/f1d47126bf13d1c9dccaa6c53b72217fd0474968/src/system_error): the 16-byte `runtime_error` followed by `error_code {int, const error_category*}`, 32 bytes, so its copy constructor and assignment copy the code too. The generic category is a static libc object with VC12's `error_category` virtual order (destructors, `name`, `message`, `default_error_condition`, the two `equivalent`), not the console's `_Error_objects<int>::_Generic_object`, and the new `generic_category()` export returns that object; a title's inline category object in a bundled libc can still have a different identity. Its `message` and direct message export construct the existing [GuestLocale::String](../../../core/libs/prx/libc/include/GuestLocale.hpp) model: a reserved eight-byte word, 16-byte inline buffer, length and capacity, with guest `operator new` storage above 15 bytes. This 40-byte string layout and virtual return ABI have not been verified against a console library. The deleting destructor still throws. `_Syserror_map` covers the 72 distinct Dinkumware `errc` values present in FreeBSD 11.4 [errno.h](https://github.com/freebsd/freebsd-src/blob/releng/11.4/sys/sys/errno.h), returning null for other values; category messages use `unknown error` for those. First-match aliases are `EAGAIN`/`EWOULDBLOCK` -> `operation would block` and `ENOTSUP`/`EOPNOTSUPP` -> `not supported`. STREAMS-only errno assignments absent from that header (`ENODATA`, `ENOSR`, `ENOSTR`, `ETIME`) are not inferred
 - [Call tracing](../../../core/libs/prx/libc/src/specifics/windows/CallTrace.cpp) (`--trace-imports`, `APS5_TRACE_CALLS`) exists on Windows only and records the entry of a call, not its arguments or its result. One process-wide ring keeps the last 65536 calls, so a thread that calls often pushes the others out. Calls are also counted per traced target since start-up; an import bound to a target already traced under another name is counted under the first name. The thunk saves the integer argument registers and `xmm0` to `xmm7`; arguments in wider vector registers pass only as long as the recording code stays free of AVX instructions, which is not tested
 - [_Dtest](../../../core/libs/prx/libc/src/Math.cpp) (libc) follows Dinkumware double classification matching _FDtest: finite values return -1, subnormals -2, zeros 0, infinities 1, and NaNs 2.
+- [app0.zar](../../../core/libs/prx/libc/src/AppArchive.cpp) (libc) - a [ZArchive](https://github.com/Exzap/ZArchive) beside `app0/` is a read-only layer under it: a path missing from `app0/` is looked up in the archive, case-insensitively. It is not a console format; titles ship their files in a PFS image instead. Resolving an archive-only path through any call other than the archive-aware libkernel ones throws, so `fopen`, `stat`, `access`, `opendir` and the rest do not read the archive yet, and `opendir` of a directory that exists in both places, `app0/` itself included, and `fdopen` of an archived descriptor throw instead of missing its entries or reading the null device. A damaged compressed block throws instead of returning `EIO`

Subject: [PATCH 0543/1000] feat(libkernel): serve app0.zar files through the
 file calls

sceKernelOpen and open give an archived file a read-only null-device descriptor. Reads, positioned, vectored and AIO reads, seeks, fstat and FIONREAD are served from the archive; dup, dup2 and F_DUPFD share the position. sceKernelStat and sceKernelCheckReachability see archived paths.

Writing opens fail with EROFS, O_CREAT|O_EXCL with EEXIST and O_DIRECTORY on a file with ENOTDIR. Opening an archived directory or one merged with the disk throws until getdents can list it.

 - [getpriority](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) follows FreeBSD 11.4's [`sys_getpriority`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_resource.c#L93-L165) for the only guest process, which is taken to run at nice 0: `PRIO_PROCESS` and `PRIO_PGRP` with 0 or its own pid (the guest is taken to lead its own process group, see `kill`) and `PRIO_USER` with 0 or its user id 0 return 0, any other id fails with `ESRCH` and any other `which` with `EINVAL`. As in FreeBSD's libc, where `getpriority` is the bare system call, errno is left unchanged on success. The nice value of a title process on the console is unverified, and the host nice of the process or of the threads `APS5_THREAD_PRIORITY=high` raises is not reported. `setpriority` accepts the same target ids (any other id fails with `ESRCH`, any other `which` with `EINVAL`), clamps the value to FreeBSD's `PRIO_MIN`-`PRIO_MAX` (-20 to 20) and stores it as the guest process's nice value, which `getpriority` returns; the host scheduling class is not changed, and whether a title process may lower the value without privilege is unverified
 - [rtprio_thread, pthread_setconcurrency, pthread_getconcurrency](../../../core/libs/prx/libkernel/Pthread/Posix/Thread.cpp) (libkernel) - `rtprio_thread` follows FreeBSD 11.4's `rtprio_thread(2)`. Every guest thread here runs under `SCHED_FIFO` or `SCHED_RR` (priority 256-767), whose rtprio class is real-time; the console's mapping from that priority to the rtprio `prio` range (0-31) is unmeasured, so `RTP_LOOKUP` and `RTP_SET` throw for such a thread rather than report an impossible priority. A thread that is not real-time reports `RTP_PRIO_NORMAL` (3) with 0, and `RTP_SET` accepts only that value. Another function fails with `EINVAL`, a null `rtprio` with `EFAULT`, a thread other than the calling one throws, and an id that is not a live guest thread with `ESRCH`. `pthread_setconcurrency` stores 0 or more and returns `EINVAL` for a negative level (the error itself, as FreeBSD's libthr does, with errno untouched); `pthread_getconcurrency` returns the level, which is a hint and changes nothing about the host's concurrency. Morrowind (`mshivam019/morrowind-ps5`) imports all three at start-up
 - [sceKernelVirtualQuery](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) returns [VirtualQueryInfo](../../../core/libs/SceTypes.hpp) with a one-byte flag allocation unit so Windows and SysV hosts return the same 72-byte representation, with the name at byte 33 and GPU mask at byte 65. This preserves the existing SysV representation; the console offsets beyond the address, protection and size fields observed in Astro Bot's AGC calls are not hardware-measured. Size and offset assertions plus a raw-byte named-mapping regression guard the host ABI.
+- [app0.zar files](../../../core/libs/prx/libkernel/File/src/ArchivedFile.cpp) (libkernel) - `sceKernelOpen`, `open`, `sceKernelStat` and `sceKernelCheckReachability` resolve a path missing from `app0/` in `app0.zar`. An archived file is a read-only host null device whose reads, positioned and vectored reads, AIO reads, seeks, `fstat` and `FIONREAD` are served from the archive, with the position shared by `dup`, `dup2` and `F_DUPFD`; writes fail with `EBADF` as on a read-only descriptor, opening one for writing or truncation fails with `EROFS` and `O_CREAT | O_EXCL` with `EEXIST`. `fstat` and `sceKernelStat` report mode `0444` (`0555` for a directory), the node index as inode and the archive file's device and times. Opening an archived directory or a directory present both on disk and in the archive throws, as `getdents` would miss entries; `mmap`, record locks, `lstat` and the other path calls on archived files are not implemented

 Some applications also need their original `app0/sce_sys/param.json` at runtime. AnyPS5 reads this file for the title ID and display name; it must contain a non-empty `titleId` string and a non-empty `localizedParameters` object with a language entry that has a non-empty `titleName`. It selects the entry named by `defaultLanguage` (inside `localizedParameters`, or at the top level); if that entry is absent, it tries `en-US`, then the first object-valued language entry. Preserve the values from the title's own metadata and place the file under the same `app0/` directory as the other app resources. At startup, its presence in the working directory creates `data/`; a non-zero `downloadDataSize` also creates `download0/`. Without the file, neither directory is created. If it is missing or invalid, metadata calls such as title/window setup can fail with a `param.json` error.
 
+Resources can also be packed into `app0.zar` beside `app0/`, a [ZArchive](https://github.com/Exzap/ZArchive) whose root is the `app0/` directory. A file present in `app0/` is read from there and any other file from the archive; the executable, `sce_module/` and `sce_sys/` stay in `app0/`. The archive is read only through `sceKernelOpen`/`open`, the read, seek and stat calls on its descriptors and `sceKernelStat`; other calls on an archived path, listing a directory that the archive also contains and opening a file in it for writing fail as described in [technical debt](../dev/debt/libkernel.md). An archive that cannot be opened stops the title at its first file access.
+
 Use the generated files printed as `Guest module:` for bundled title modules. `libs/` is for AnyPS5 system libraries, not the original PS5 `.prx` files. Placing an original PS5 module in `libs/` on Windows makes Windows try to load it as a DLL and can fail with error 193 (not a valid Win32 application).
 
 On Windows, a self-built `libs/` also needs `libgcc_s_seh-1.dll`, `libstdc++-6.dll` and `libwinpthread-1.dll` from the `mingw64/bin` directory of the toolchain that built the libraries; the release archives already contain them. The libraries are loaded without searching `PATH`, so a copy elsewhere on the system is not used, and a library that needs one of them fails with error 126 (the specified module could not be found) although its `.prx` file is present.

Subject: [PATCH 0545/1000] fix(libkernel): refuse descriptor calls on app0.zar
 files

flock, fstatfs, ftruncate, fsync, fdatasync, getdirentries, fchmod, futimes and mmap on an archived descriptor acted on its null device and succeeded or failed with an unrelated errno. They now throw NotImplemented, each covered by the kernel archive test; mmap is noexcept, so its refusal is checked through the terminate handler.

As in FreeBSD's libc, where `getpriority` is the bare system call, errno is left unchanged on success. The nice value of a title process on the console is unverified, and the host nice of the process or of the threads `APS5_THREAD_PRIORITY=high` raises is not reported. `setpriority` accepts the same target ids (any other id fails with `ESRCH`, any other `which` with `EINVAL`), clamps the value to FreeBSD's `PRIO_MIN`-`PRIO_MAX` (-20 to 20) and stores it as the guest process's nice value, which `getpriority` returns; the host scheduling class is not changed, and whether a title process may lower the value without privilege is unverified
 - [rtprio_thread, pthread_setconcurrency, pthread_getconcurrency](../../../core/libs/prx/libkernel/Pthread/Posix/Thread.cpp) (libkernel) - `rtprio_thread` follows FreeBSD 11.4's `rtprio_thread(2)`. Every guest thread here runs under `SCHED_FIFO` or `SCHED_RR` (priority 256-767), whose rtprio class is real-time; the console's mapping from that priority to the rtprio `prio` range (0-31) is unmeasured, so `RTP_LOOKUP` and `RTP_SET` throw for such a thread rather than report an impossible priority. A thread that is not real-time reports `RTP_PRIO_NORMAL` (3) with 0, and `RTP_SET` accepts only that value. Another function fails with `EINVAL`, a null `rtprio` with `EFAULT`, a thread other than the calling one throws, and an id that is not a live guest thread with `ESRCH`. `pthread_setconcurrency` stores 0 or more and returns `EINVAL` for a negative level (the error itself, as FreeBSD's libthr does, with errno untouched); `pthread_getconcurrency` returns the level, which is a hint and changes nothing about the host's concurrency. Morrowind (`mshivam019/morrowind-ps5`) imports all three at start-up
 - [sceKernelVirtualQuery](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) returns [VirtualQueryInfo](../../../core/libs/SceTypes.hpp) with a one-byte flag allocation unit so Windows and SysV hosts return the same 72-byte representation, with the name at byte 33 and GPU mask at byte 65. This preserves the existing SysV representation; the console offsets beyond the address, protection and size fields observed in Astro Bot's AGC calls are not hardware-measured. Size and offset assertions plus a raw-byte named-mapping regression guard the host ABI.

Opening an archived directory or a directory present both on disk and in the archive throws, as `getdents` would miss entries; `mmap`, record locks, `lstat` and the other path calls on archived files are not implemented

The meaning of the second argument is unknown. PRAGMATA (PPSA02530, #5726) and Onimusha: Way of the Sword (PPSA27836) pass `0x4000000` as a constant: Onimusha calls it for every keycode from 0 to 0x8F to build a table of key names, upper-cases `a` to `z` itself and skips keycodes that fail or return 0, so that bit is ignored and the unshifted character is returned as for 0. Any other bit throws, and so does a keyboard type other than 0.

Subject: [PATCH 0548/1000] fix(libkernel): append O_APPEND writes atomically
 on Windows

On Windows the C runtime appends by seeking to the end and then writing,
so concurrent appends through different descriptors overwrite each other
and lose data. Write and writev on an O_APPEND descriptor now go through
WriteFile at the end-of-file offset, which Windows appends atomically,
and writev gathers its buffers into one append as FreeBSD writes the
whole vector at the end.

Subject: [PATCH 0549/1000] fix(libSceNgs2): support custom filter type 0 in
 Ngs2ApplyCustomParam

Allow custom voice filter type 0 to clear the destination filter,
matching the sampler filter convention. Type 1 continues to configure
the biquad frequency, Q and level. Other unsupported filter types
still throw.

This follows the listener-transform support in
fix/libSceNgs2-listener-transform and is needed for Dead Cells
(PPSA15552), which reaches this path after the custom sampler rack.

Depends on: fix(libSceNgs2): support listener transforms in sceNgs2GeomCalcListener- #5810
Unblocks: PPSA15552
AI assistance: yes

 - [sceNgs2PanInit / sceNgs2PanGetVolumeMatrix](../../../core/libs/prx/libSceNgs2.native/src/Pan.cpp) (libSceNgs2.native) - follow the PS4 firmware 11.00 `libSceNgs2.sprx`, read and checked against its output for 2, 4, 5 and 7 speakers into 1, 2, 6 and 8 channels; not yet confirmed on the PS5 library. Speakers are taken in the order L R, L R Ls Rs, L R C Ls Rs or L R C Ls Rs Lb Rb and kept in a fixed circular order, not sorted; without angles the defaults are 90/270, 40/110/250/320, 0/40/110/250/320 and 0/40/110/150/210/250/320 degrees. As in that library, defaults converted to radians keep the wrap-around entry in degrees, so angles past the last speaker pan almost fully to it. Error codes are not known for the PS5, so invalid arguments throw, including a speaker angle equal to the unit angle, on which that library loops forever. Angles so large that adding or subtracting a turn leaves them unchanged throw for the same reason
 - [sceNgs2GeomResetListenerParam, sceNgs2GeomResetSourceParam](../../../core/libs/prx/libSceNgs2.native/src/Geom.cpp) (libSceNgs2.native) - the structures (12, 16, 16, 60, 96, 108, 32 and 308 bytes) come from [KytyPS5](https://github.com/KytyPS5/KytyPS5)'s `ngs2.cpp` and match [shadPS4](https://github.com/shadps4-emu/shadPS4)'s `ngs2_geom.h` field for field, but only KytyPS5 gives the behaviour - shadPS4 logs and returns success without writing the output. The defaults (orient front +Z, orient up +Y, sound speed 343, cone 1/360/1/360, rolloff 0/1000000/1/1, doppler factor, full-band, LFE and maximum level 1, two speakers and matrix format 2) are unverified on a PS5 title; KytyPS5 and iStark/PS5PCEM agree on them. PPSA15552 (Dead Cells) calls `sceNgs2GeomResetSourceParam` after creating its racks. A null output address returns `INVALID_OUT_ADDRESS` as elsewhere in the library rather than throwing as KytyPS5 does. `sceNgs2GeomApply` stays unimplemented
 - [sceNgs2GeomCalcListener](../../../core/libs/prx/libSceNgs2.native/src/Geom.cpp) builds an orthonormal world-to-listener transform. The row-major matrix, front-axis priority and flag 1 for right-handed input follow [PS5PCEM](https://github.com/iStark/PS5PCEM/blob/d2534bac6325a2c61c0fa88977e5321074304484/src/hle/ngs2_geom.zig); they have not been measured on PS5 hardware. Velocity stays in world coordinates and positive finite sound speed is preserved. Orientation vectors are normalised and up is made perpendicular to front, so non-unit and slightly tilted vectors are accepted; unknown flags, zero or parallel orientation vectors, nonfinite input and an unrepresentable translation throw without changing the output; console error codes are unknown, and a nonpositive sound speed throws where PS5PCEM and [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/df5b9b92be7dfd463b47756b707d6d356a9f0550/src/libs/ngs2.cpp) default it to 343. KytyPS5 always writes the identity matrix, so the transform rests on PS5PCEM alone. Dead Cells (PPSA15552) reaches this call after the custom sampler rack in #4334. This does not implement source attenuation, panning or Doppler in `sceNgs2GeomApply`.

PPSA15552 (Dead Cells) calls it on custom sampler voices with a 48-byte buffer at two sites (eboot `0x1740f90`, `0x1741009`) and reads only the 64-bit value at offset 16: the first site keeps it and the second subtracts the kept value, so it is filled with the voice's decoded sample count. Other sizes return `INVALID_OUT_SIZE` as for the other racks. The state flags fill the common voice state; the remaining fields stay zero. shadPS4's `OrbisNgs2CustomSamplerVoiceState` is about 80 bytes and does not match the size this title passes, so the field names and the console's value are unverified

Subject: [PATCH 0551/1000] feat(agc): replay prepared shader capture and
 materialization offline

Add a CPU replay mode that reaches the runtime descriptor checks and specialization used by prepared shader invocations. Test active and inactive guarded descriptors and continuation after a failed request.

Subject: [PATCH 0553/1000] feat(psml): implement the MFSR shared-resource and
 800 context setup

scePsmlMfsrInit, the shared-resource calls and the 800M3_2 context calls
threw or answered "not initialized", so a title that sets PSSR up at
start-up stopped there even when it never uses PSSR on hardware without
it (PPSA08330 calls the setup unconditionally and only dispatches when
sceKernelIsTrinityMode is set, which AnyPS5 reports as 0).

The layouts come from the calls in PPSA08330 and PPSA03016: requirements
are {block bytes, alignment, block count}, handles are 8-byte values
written through the first argument, and a context parameter carries its
block list at 8/16 and the shared-resources handle at 0x38. Init sets
the initialized state, the requirements ask for four 2 MiB blocks (what
PPSA08330 allocates regardless of the returned count), and create and
release keep bookkeeping objects. Invalid arguments throw because their
error codes are unknown.

The 1100 calls, scePsmlMfsrCreateContext1300 and the 900/1000/1300
dispatch packets keep returning 0x8A810001 before Init and throw after
it; packet size, mip bias and capture still throw.

The guest test links libc and gets Windows unwinding so it can check the
refused calls.

+- [scePsmlMfsrInit](../../../core/libs/prx/libScePsml_debug/Export.cpp) (libScePsml) - succeeds and only sets the initialized state; the shared resources and contexts are bookkeeping objects that use none of the guest blocks. Whether Sony's library fails on hardware without PSSR is unknown. PPSA08330 calls the setup unconditionally and only uses a context when its cached `sceKernelIsTrinityMode` result is set (0x3c643d, 0x567f97; otherwise it stores a -0.25 mip bias itself at 0x567fe2), which AnyPS5 reports as 0, so the dispatch, mip bias and capture calls still throw

Subject: [PATCH 0554/1000] fix(psml): check the shared resources and add the
 context under one lock

A concurrent scePsmlMfsrReleaseSharedResources could pass its "still used
by a context" check between the handle lookup and the context insertion.
The technical debt entry now says how KytyPS5's layout differs from the
calls in PPSA08330 and PPSA03016.

Subject: [PATCH 0555/1000] perf(agc): linear color targets over imported
 memory get a resident image

A linear color target took a synchronous draw (copy in, draw, copy out, CPU
wait) on every draw. When its memory already has a host import, it now gets a
resident image like tiled targets, and keepRecordedDraw stores its results back
to guest memory right after the draw with a recorded GPU store (FlushPending),
so CPU readers see them as before, without the wait. No import is created for
it (a lookup only): memory without one keeps the synchronous path.
APS5_NO_RESIDENT_LINEAR=1 restores the old path.

GTA V Story (RTX 4090, upstream main eb901bcf4 + #6488): 14.64 -> 16.47 FPS.

The error codes follow the other pad calls. Controllers are local devices, so the answer is always false
 - [scePadSetAngularVelocityBiasCorrectionState](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - inferred signature `(int handle, bool enabled)` follows `scePadSetTiltCorrectionState` and `scePadSetAngularVelocityDeadbandState`; an invalid handle returns `PAD_ERROR_INVALID_HANDLE`, disabling is a no-op, and enabling throws because bias correction is not modelled

Neither error has been confirmed on PS5 hardware

Queue destruction is assumed to reject blocked callers with `ULT_ERROR_BUSY` and otherwise discard queued data; pool exhaustion returns `ULT_ERROR_AGAIN`.

 NativePositionedTransfer

Its callers (NativePositioned_nid_no_patch, the vectored transfer) already hold the
non-recursive per-descriptor lock, so locking again deadlocked every positioned transfer.

Subject: [PATCH 0565/1000] test(agc): shut libc down before agc_shader_helpers
 returns

On Windows, agc_shader_helpers returned from main with the driver's
threads still running. ExitProcess ends them first, then the DLLs'
static destructors run and wait on what those threads left locked:
the async log's queue mutex in Driver::stop, DeviceUseGate's condition
variable in ~Driver, and condition variables in libkernel's statics.
The test hung after printing its result in about one ctest run of
three on a Radeon 860M (#6791).

Like the other driver tests, it now runs LibcRunShutdown_nid_postfix
before returning, which stops the driver while its threads are alive.

+### Silent stubs
+
+- [sceVoiceGetPortAttr](../../../core/libs/prx/libSceVoice/Export.cpp) (libSceVoice) - attribute 1001 writes one zero byte and returns 0 for an existing port; the backend processes no voice audio. PPSA34501 requests size 1 and reads one byte on success, and this fallback avoids its startup exception. The name follows attribute 1001 (`CELLVOICE_ATTR_VAD`) (Voice Activity Detection) in [RPCS3](https://github.com/RPCS3/rpcs3/blob/master/rpcs3/Emu/Cell/Modules/cellVoice.h), not confirmed for the PS5. The correct result, eligible port types and behaviour are unknown;
+
 ### Unknown function info
 
 - [sceVoiceResetPort](../../../core/libs/prx/libSceVoice/Export.cpp) (libSceVoice) - the `(uint32_t portId)` signature is the PS Vita one in [VitaSDK](https://github.com/vitasdk/vita-headers/blob/ae5808f3105c42fa3373ba4ab64ab54e2e3ca848/include/psp2/voice.h#L503-L514) and the PS3 `cellVoiceResetPort` in [RPCS3](https://github.com/RPCS3/rpcs3/blob/be69c054eeac57e2e671697a463473d37fe5a7b2/rpcs3/Emu/Cell/Modules/cellVoice.cpp#L493-L510); that the PS5 library takes the same argument is assumed. A reset clears a port's buffered data, and ports here buffer nothing (`sceVoiceReadFromOPort` returns 0 bytes and `sceVoiceWriteToIPort` throws), so it only checks that the library is initialized and the port exists, as RPCS3 does, and keeps the port's connections, volume and mute flag. An uninitialized library or an unknown port throws like the other port calls; the console's error codes are not measured. PPSA23566 imports it

Subject: [PATCH 0569/1000] test(agc): make the null-image fixture module and
 layout agree

The stencil null feedback fixture splices a storage image array into the
fragment module by hand. spirv-val rejects the result with "Decorate is
in an invalid layout section": the decorations were inserted in front of
the first OpTypeVoid, which the recompiler emits after its Input and
Output variables. The binding also used set 1 with the vertex-group
number of a different heap kind (the 1D array one, not the 2D image the
module declares), so the set layout the driver builds from the binding
metadata (binding / 65 picks the set) put it in set 0 while the module
declared set 1.

Insert the decorations after the existing annotations, declare the image
array type the recompiler emits for a float 2D storage heap, list the
variable in the SPIR-V 1.4 entry point interface like the recompiler
does, and number the binding as the recompiler does for the fragment
stage, in the descriptor set the target uses. When built with
ANYPS5_ENABLE_SPIRV_TOOLS the fixture validates its module against the
Vulkan 1.1 environment.

 ### Functional
 
+- [Native multisampled DCC fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) import uniform 0000/0001/1110/1111 keys into a single-layer, level-zero SW_64KB_R_X color image with 2, 4 or 8 fragments. Color and DCC/CMASK ranges must stay write-watched and unchanged; expanded or mixed initial DCC, register CMASK clears, compressed payloads, color transforms, lossy modes, metadata changes, guest publication and writes over a live owner throw. Driver-mediated reads of the color and metadata stay guarded. The metadata extent follows [AMD Addrlib](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp#L347-L454) with the [PS5 Mesa model](https://github.com/mihawk-99/PS5_Mesa/blob/0b2d6d1a61d9bbf89cf8beb88a696144f67c61f8/src/amd/vulkan/winsys/ps5/radv_ps5_winsys.c): GFX10.1, 16 pipes, 256-byte interleave, two maximum compressed fragments. Console geometry, concurrent guest mutation and transitions outside this subset are unverified.
+
 - [Initial stencil state](../../../core/libs/prx/libSceAgcDriver/Execution/include/QueueState.hpp) uses zero for `DB_STENCIL_CONTROL`, `DB_STENCILREFMASK` and `DB_STENCILREFMASK_BF` (context `0x10b`-`0x10d`), including after `CLEAR_STATE`. The public V0, V4, V5 and V7-V11 [register-default tables](../../../core/libs/prx/libSceAgc/Command/include/RegisterDefaultsData.hpp) supply these values. Linux's [GFX10 clear-state table](https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/amd/amdgpu/clearstate_gfx10.h) agrees on the control register but uses `0x01000000` for the reference masks; the console reset values have not been measured. Planet Coaster (PPSA01736 v01.017) enables stencil tests without writing the control register.
 - [Type-0 and type-1 texture descriptors](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestTextureResource.cpp) (`TYPE` = 0 or 1 in dword 3) with a nonzero base are bound as null images, like a zero base. TYPE 0 comes from a gfx1036 (RDNA2) measurement in issue #4139 (image sample, load and resinfo return zero, no fault). TYPE 1 comes from a gfx1010 (RDNA1) measurement in #4139 and #5828 (`image_sample_lz`, `image_sample_b`, `image_load` and `image_get_resinfo` return zero, no fault) with format 22 only; TYPE 1 is not measured on RDNA2, with other formats or with depth-compare reads (`image_sample_c*`). Neither type was measured on the console's gfx1013.
 - [Multisampled color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) lose their guest-read guards and cannot be reused after a successful allocation removal or unmap covers their full guarded range. Retired Vulkan images remain allocated until device teardown to preserve outstanding references. Partial unmaps keep the guard; partial allocation reuse and guest access to live multisampled data remain unsupported.

Subject: [PATCH 0571/1000] ci(windows): cache only the submodule git dirs

The cached tar held the 3rdparty work trees too, and its extraction fails on
the dangling symlink 3rdparty/zstd/tests/cli-tests/bin/unzstd, which Git Bash
tar can't create. Cache .git/modules alone and let git submodule update check
the work trees out from it, as a clean checkout does.

Subject: [PATCH 0572/1000] feat(agc): keep Windows imports under 1 MiB
 compared with APS5_NO_DEFERRED_SETTLES

The deferred settle of small Windows imports could only be turned off
through the test hook. The variable turns it off for a run, so a title can
be compared with and without it on one build; unset, nothing changes.

 - A draw whose `PA_SC_AA_CONFIG` selects 2, 4 or 8 samples renders into host-only multisampled images. [`MultisampleTarget.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) keeps one image per device, surface address, format, extent and sample count (`MultisampleTargetView`); the pipeline, render pass and library keys carry `State::samples`, and a multisampled depth target is a multisampled depth surface. The guest sample planes and FMASK are never read or written, so the registry also guards the target's guest range: a CPU read (`GuestMemory::SetReadGuard`), a DMA copy, and a sampled or storage image read of it throw. A `CB_COLOR_CONTROL` resolve mode over a multisampled CB0 runs as a render pass whose resolve attachment is CB1's resident image (`ResolveMultisampleTarget`). A zero fill of the target's CMASK (`NoteColorMetadataFill`, from fill kernels and CP DMA fills) clears the image at its next use.
 - A texture over a depth surface samples the depth image itself when it views one 2D slice of the plane's own format (`DepthSurfaceTexture` in [`DepthSurface.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp)). A view of several slices (a 2D array or a cube) or an integer view of a D16 plane is served by a `DepthPlaneCopy`, an image the slices are copied into at every use: from the depth surface bound at each slice's address, else from guest memory. Such a texture is never kept in the resource templates (`RefreshedPerUse`).
 - Guest memory reaches the GPU through host imports (`VK_EXT_external_memory_host`) where the driver accepts them, and through copies otherwise ([`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp)). A registered range larger than the import window (64 MiB) is imported per window for buffer and fill accesses and whole for an address-based build. Live imports stay under a budget, with the least recently used import retired first (see TechnicalDebt, Host import windows and budget).
-- On Windows, a host import of private `MEM_WRITE_WATCH` memory (singly mapped direct memory) stays on `GetWriteWatch` when `ProbeImportWriteProtection` shows the driver reports nothing written after the second GPU read and a GPU write, and a CPU store is collected (`decideImportWatch`). The driver marks every page of such an import written, asynchronously, until a GPU use of it completes (a read on the settle queue ends it even while main-queue work that used the import first is still running, and the first use of an earlier import of the same pages after that read marks nothing), so `settleImport` in [`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) copies 4 bytes out of the new import on a second queue of the graphics family, or on a queue of another copy-capable family when the graphics family has only one (`Context::settleQueue`, own pool and mutex) inside `ImportWatched`'s window and waits for it, for imports of 1 MiB or more; the main queue can't be used there because `importAllocation` holds the imports lock and `GpuMutex` comes before it in the lock order. A smaller import is compared when it is made, so a title that maps, imports and unmaps a small buffer around every submission does not block its mapping thread. Its 4-byte read is queued instead: the next import lookup that holds `GpuMutex` while the imports match the registry (`settleUnwatchedImports`) records the queued reads into one batch on the settle queue, and once the batch's fence has signalled a later lookup returns the import's whole 64 KiB blocks to the write watch (`GuestMemory::Rewatch` drops their marks and stamps every block as a CPU store), except while storage results are pending over them. A settled import whose range had already left the watch returns the same way, and an import retired while its read is in flight is kept with that batch and freed once the batch has completed, without waiting for it; a guest unmap of its memory waits for the batch instead. Imports through a section alias keep tracking on the guest views, and every other Windows host import is compared. A device without such a queue keeps the comparisons. On Linux the settle queue is made when the device imports dma-buf memory, and every dma-buf import of 1 MiB or more is settled right after it is made, for another reason: the kernel maps an import's pages for the GPU at the first submission that uses it, which took about 2 s for a 3 GiB import on RADV and held up the title's frame. The import's buffer is shared with the settle queue's family instead of aliased, since a sparse import is bound to many memory objects.

 - [sceAudio3dPortOpen](../../../core/libs/prx/libSceAudio3d/Export.cpp) (libSceAudio3d) - buffer modes 0 and 1 (also selected by the 0x10 and 0x18 parameter sizes) and 3 beds depend on an SDK version check in the module ([prosper](https://github.com/mattias800/prosper)) and throw. A repeated `sceAudio3dInitialize` (`NOT_READY` in shadPS4, 0 in prosper) and `sceAudio3dPortAdvance` on a full queue (`NOT_READY` in shadPS4, unhandled in KytyPS5) throw too
+- [sceAudio3dPortGetAttributesSupported](../../../core/libs/prx/libSceAudio3d/Export.cpp) (libSceAudio3d) - the supported list (late reverb level, downmix spread radius, downmix spread height aware) is inferred from the attributes `sceAudio3dPortSetAttribute` accepts; its order and the count written when the caller capacity is smaller are unverified. [shadPS4](https://github.com/shadps4-emu/shadPS4) returns object attributes (PCM, gain...) instead, prosper and KytyPS5 have no body
 - [sceAudio3dObjectReserve](../../../core/libs/prx/libSceAudio3d/Export.cpp) (libSceAudio3d) - object ids, the `max_objects` limit and the checks of `sceAudio3dObjectReserve` and `sceAudio3dObjectUnreserve` follow [shadPS4](https://github.com/shadps4-emu/shadPS4) (PS4), the only reference with a body: ids count up from 1 per port, skipping 0, 0xFFFFFFFF and ids in use, and a failed reserve writes 0xFFFFFFFF

Subject: [PATCH 0578/1000] fix(libSceNgs2): implement a minimal
 sceNgs2GeomApply pass-through

Implement sceNgs2GeomApply, which was previously an unimplemented
throwing stub and was blocking Dead Cells (PPSA15552).

The implementation validates null handles/output addresses and writes a
minimal Ngs2GeomAttribute: pitch_ratio 1.0, source position, source
volume/level maxima, and diagonal channel levels for the source's channel
count. It does not implement source attenuation, distance rolloff, panning
or Doppler.

The export lives in Geom.cpp's internal Ngs2GeomApply and is exposed through
the existing default-visibility wrapper in Voice.cpp. Unimplemented.cpp no
longer defines the stub. A passing test was added to Ngs2Geom.cpp.

Unblocks: PPSA15552 #<Game bring-up discussion number>
Depends on: none
AI assistance: yes

KytyPS5 always writes the identity matrix, so the transform rests on PS5PCEM alone. Dead Cells (PPSA15552) reaches this call after the custom sampler rack in #4334.

Structure layouts come from [shadPS4's ngs2_custom.h](https://raw.githubusercontent.com/shadps4-emu/shadPS4/main/src/core/libraries/ngs2/ngs2_custom.h) (OrbisNgs2CustomVoiceFilterParam, 40 bytes) and live trace correlation from [prosper's hle_audio.cpp](https://raw.githubusercontent.com/mattias800/prosper/main/prosper/src/hle/audio/hle_audio.cpp) (0x40001300 command and parameters like 10000.0f and 0.707f). Routes parameter updates via the 0x40001300 command family into the Biquad filter engine. Filter type 0 clears the destination filter; type 1 configures the RBJ low-pass biquad frequency, Q and level. Other filter types and unmodeled configurations throw.
 - [sceNgs2VoiceGetState custom sampler](../../../core/libs/prx/libSceNgs2.native/src/Voice.cpp) (libSceNgs2.native, rack 0x4001) - only the size and one field come from a title. PPSA15552 (Dead Cells) calls it on custom sampler voices with a 48-byte buffer at two sites (eboot `0x1740f90`, `0x1741009`) and reads only the 64-bit value at offset 16: the first site keeps it and the second subtracts the kept value, so it is filled with the voice's decoded sample count. Other sizes return `INVALID_OUT_SIZE` as for the other racks. The state flags fill the common voice state; the remaining fields stay zero. shadPS4's `OrbisNgs2CustomSamplerVoiceState` is about 80 bytes and does not match the size this title passes, so the field names and the console's value are unverified

Subject: [PATCH 0580/1000] fix(libSceSystemService): report the host time zone
 and summer time

sceSystemServiceParamGetInt answered 0 for the time zone (parameter 4)
and summer time (parameter 5), so the console looked set to UTC while
libSceRtc and libc convert local time with the host's zone. Titles add
the time zone in minutes and 60 more minutes when summer time is 1 to
UTC to get the local time (Apollo, GoldHEN's frame logger). Both now
follow the host's local time zone: summer time is whether it is in
effect, and the time zone is the current offset east of UTC less the
summer time shift while it is.

On Windows that shift is the C runtime's own summer time bias
(_get_dstbias), the one localtime_s applied, not a fixed 60 minutes.
The UCRT reads the system zone when libc.prx loads and keeps that
zone's bias after TZ is set later, so on a host whose system zone has
no summer time (the CI runner's UTC) a TZ of CET-1CEST shifted by 0 and
the time zone came out as 0. The cause and the change are screamm's,
from the review.

For a host zone whose summer time is not one hour, Linux keeps the sum right and the standard offset wrong, and Windows the opposite; how the console reports such a zone is unknown. libkernel's `sceKernelConvertUtcToLocaltime`, `sceKernelConvertLocaltimeToUtc` and `sceKernelGettimezone` still use UTC

+- [NGS2 system and rack handle errors](../../../core/libs/prx/libSceNgs2.native/include/Ngs2Types.hpp) use `0x804A8201` and `0x804A8202`, following the native handle-type error helper recorded in [prosper's PS5 module analysis](https://github.com/mattias800/prosper/blob/d61eb2c0ad2de879ef74df9c4aa050c512804a18/prosper/src/hle/audio/hle_audio.cpp). [sceNgs2RackGetVoiceHandle](../../../core/libs/prx/libSceNgs2.native/src/Rack.cpp) resolves the rack before checking the output pointer, matching the export in firmware 1.00 through 12.70 reported in [#5916](https://github.com/boykopovar/AnyPS5/pull/5916#issuecomment-6172832590). Other exports retain their existing validation order; complete invalid-input precedence and console execution remain unverified.
+
 - [NGS2 render buffer capacity](../../../core/libs/prx/libSceNgs2.native/src/Render.cpp) is treated as available storage for one configured grain. PPSA01880 passes 303104 bytes for 256 stereo float frames (2048 bytes); rendering writes or clears only those frames and preserves the remaining capacity. Non-null silent outputs now undergo the same supported-format and minimum-size checks as audible outputs, with channel counts limited to 1 through 8. Unused null outputs remain ignored. The console's handling of surplus capacity and invalid silent output descriptors has not been measured; invalid descriptors throw rather than return guessed SDK errors.
 - [NGS2 ATRAC9 waveform loops](../../../core/libs/prx/libSceNgs2.native/src/Atrac9.cpp) accepts one integer forward `smpl` loop. Inclusive RIFF endpoints and encoder-delay adjustment follow [vgmstream riff.c](https://github.com/vgmstream/vgmstream/blob/7dc938fa2f210943b37c7b6511852b516ef432ab/src/meta/riff.c). PPSA03747 supplies a 60-byte sampler chunk with one loop, `samplerData` 24, start 256, inclusive end 299224 and delay 256 for 298969 audible samples. The chunk size and loop count bound the records; `samplerData` is not interpreted. Output positions are assumed to use audible samples and an exclusive end. Blocks split into an optional intro, a repeated range and an optional tail; zero play count means infinite repeats, positive play count includes the first pass. ATRAC9 ranges include a preceding codec frame for decoder history. The output block layout, repeat-count mapping and error codes are unverified on hardware. Multiple, reverse, alternating and fractional loops throw.
 - [NGS2 submixer UserFx](../../../core/libs/prx/libSceNgs2.native/src/Custom.cpp) (control `0x20000004`) invokes the title's callback after input mixing on every playing grain, including silence. The 40-byte control and 48-byte process context follow [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/945dbc3cc3eee80ac3e053b438502ed936fa6bb2/src/core/libraries/ngs2/ngs2_submixer.h). PPSA03747 installs a peak-meter callback; its code confirms the channel pointers, user data 0, channel count, grain size and sample-rate offsets and returns 0. Other user data words are preserved. Flags are assumed to be 1 after registration/restart and 0 thereafter, following UserFx2's first-process convention; this callback does not inspect them. Null handlers disable the effect, setup clears it, and nonzero callback results throw. These lifecycle and error semantics are unverified on console hardware.

Subject: [PATCH 0584/1000] feat(libSceSsl): implement certificate serial and
 name entry readers

Implement sceSslGetSerialNumber, sceSslGetSubjectName, sceSslGetIssuerName, sceSslGetNameEntryCount, sceSslGetNameEntryInfo, and sceSslFreeSslCertName. Signatures follow VitaSDK. Mbed TLS extracts the certificate's serial number and X.509 subject and issuer distinguished names, extracting OID attribute short names (or numeric strings) and value strings.

 - [sceSslCreateConnection, sceSslDeleteConnection, sceSslSetVerifyCallback, sceSslConnect, sceSslRead, sceSslWrite](../../../core/libs/prx/libSceSsl/Export.cpp) (libSceSsl) - imported by `ffmpeg.prx`. The repository has no TLS client, so a connection only records its context, socket, host and verification callback, and `sceSslConnect`, `sceSslRead` and `sceSslWrite` throw `NotImplemented_nid_no_patch(__func__)` until there is a transport. Signatures follow [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/60977b29103452b9681ae10c7a9011d44965bf16/src/SharpProspero/Interop/Net/Http.cs#L195-L252), which also says the socket stays open after `sceSslDeleteConnection`. An unknown context returns `SSL_ERROR_INVALID_ID` (0x8095F006), as `sceSslGetMemoryPoolStats` does on the console and as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/4865dd92ca6b6bb907748f125883093af038f53b/src/libs/network.cpp#L2688-L2720) and [sharpemu](https://github.com/sharpemu/sharpemu/blob/29021b5a71bbc80f262d887e6ba18b3a72963f49/src/SharpEmu.Libs/Network/SslExports.cs#L41-L54) return for other context calls; for an unknown connection, a connection whose context was terminated and a null host the console's codes are unknown, so these throw. The socket is not checked when the connection is created, `sceSslTerm` leaves the context's connections to `sceSslDeleteConnection`, and `sceSslSetVerifyCallback` accepts any callback, null included, and returns 0; none of this is verified on the console. `SSL_ERROR_BEFORE_INIT` (0x8095F001) is never returned, as the library keeps no state apart from its contexts

PPSA15508/01.002.000 calls `sceSslLoadCert` with one 1,408-byte PEM CA and null client certificate/key arguments; this confirms that call shape, not console error behavior. Mbed TLS 3.6.7 parses DER/PEM chains and checks an optional client certificate/key pair. Imports are retained per context and committed together; a failed import preserves existing credentials. CA queries return independently owned snapshots; unload clears active credentials while outstanding snapshots remain valid. Appending repeated CA imports, snapshot lifetime across unload, memory overhead and error precedence have not been measured on a PS5. Invalid loads, malformed material, exhausted pools and unsupported keys throw rather than inventing console error codes. No root bundle is shipped; an empty context still returns `NOT_FOUND`. The existing null-list error, unknown-context behavior and legacy clearing of foreign raw CA lists remain unchanged. Certificate readers remain unimplemented. Loading credentials neither starts a TLS connection nor authenticates a peer

Mbed TLS parses the certificate's serial number and X.509 subject and issuer distinguished names, extracting OID attribute short names (or numeric strings) and value strings. An unknown or expired certificate handle or invalid certificate name allocation throws; null output pointers or out-of-range entry indices return error codes

The verify options, the minimum version and the ALPN protocol list are recorded on the connection; nothing reads them until `sceSslConnect` has a transport, and how the console applies them is unknown. The initial verify options are unknown and taken as 0. `sceSslSetMinSslVersion` accepts the `SceSslVersion` values SharpProspero lists, 0 (none) to 5 (TLS 1.2), and throws for others; whether the console accepts a TLS 1.3 value is unknown. `sceSslSetAlpn` stores the string up to its terminator and throws for a null list; whether the console expects a comma-separated list or the TLS wire format is unknown. `sceSslGetAlpnSelected` returns null, as no handshake completes. An unknown connection and a connection whose context was terminated throw, as for `sceSslSetVerifyCallback`

Subject: [PATCH 0588/1000] fix(libSceMouse): take the position arguments of
 sceMouseResetAbsolutePosition

A call site passes the handle and then x and y as zero-extended 16-bit values (the centre of the display size), and ignores the result.

 ### Unknown function info
 
+- [scePadUnknown_n3kSX62fgNo](../../../core/libs/prx/libScePad/Export.cpp) (libScePad, NID `n3kSX62fgNo`) - firmware 13.60 returned `0x80920005` before `scePadInit` and `0x809200ff` after it in the #3177 probe; the tested call read or wrote no argument pointers. PPSA15645 calls the import after `scePadOpen`, but its return and side effects in that state are unknown. The NID name and signature are unknown, so the statuses are not named by presumed error meanings
 - [scePadSetAngularVelocityDeadbandState](../../../core/libs/prx/libScePad/src/PadState.cpp) (libScePad) - with the deadband on, each angular velocity axis whose magnitude is below 0.017453292 rad/s (1 degree per second) reads as 0, before the orientation is integrated; it starts off. Threshold, per-axis test and default follow [duaLib](https://github.com/WujekFoliarz/duaLib/blob/03bad1bea2a36561b520846776f2a07ced6773e0/src/source/duaLib.cpp#L44), which reimplements the PC `libScePad.dll`; the console's threshold is not measured, and the deadband is kept per library rather than per handle since one pad handle exists
 - [scePadOpen and scePadOpenExt](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - special ports (type 2) return `DEVICE_NOT_CONNECTED` (0x80920007) because the host has no special controller, and `scePadGetHandle` has no handle for them; whether the console opens a handle and reports the device as disconnected later is unknown. scePadOpenExt handles only special ports. PPSA01317 passes a 16-byte param that names the device by vendor and product id (`b7 0e 04 0e ...` for 0x0eb7:0x0e04) and skips the user on any negative result. Other port types throw
 - [scePadVrControllerReadState](../../../core/libs/prx/libScePad/Export.cpp) (libScePad, NID `iA-DdobUen8`) - the name hashes to the imported NID; the `(int handle, void* state)` signature follows [PS5VR](https://github.com/theghostonline/PS5VR/blob/0e408909ce7a39891a2e06eee3438d07a09e11e3/app/src/app_vr.c#L326-L369) (PPSA99177), which passes a PS VR2 Sense controller handle from `scePadOpen` type 3 or 4 and a 0x68-byte state it reads as buttons at 0, stick bytes at 4 and a connected byte at 0x40. The title calls it only after `sceHmd2Initialize` succeeds, which it does not here, so every call throws; the state layout is otherwise unknown

Subject: [PATCH 0595/1000] fix(libkernel): fail connect on a listening socket
 with EOPNOTSUPP

FreeBSD's soconnectat refuses a socket with SO_ACCEPTCONN set with EOPNOTSUPP (45). The host answers EINVAL on Windows and EISCONN on Linux, so connect() on a listening stream socket returned the host's error. Answer EOPNOTSUPP for a listening stream socket before the address is read.

Subject: [PATCH 0596/1000] fix(libkernel): validate the address before
 refusing connect on a listening socket

FreeBSD reads and checks the address (getsockaddr) before soconnect refuses a listening socket with EOPNOTSUPP, so a null or short address on a listener fails with the address error. Move the listener check after the address is read and keep it ahead of the family check.

Subject: [PATCH 0597/1000] fix(libkernel): allocate the Windows thread-local
 slot on first use

WindowsThreadLocal<T>::slot was a template static, so its dynamic
initialization was unordered against the timer self-test in Time.cpp.
With APS5_TRACE_TIMERS set, the self-test ran first, used slot 0 and
aborted every title with "Cannot bind native thread state". The slot is
now a function-local static. guest_nanosleep_timer_self_test runs
guest_nanosleep_tests with APS5_TRACE_TIMERS=1 on Windows.

Subject: [PATCH 0598/1000] test(tools): build the select_tests fixture under a
 junction where Windows refuses symlinks

The fixture builds its project under a directory symlink so that the
paths CMake records differ from the resolved ones. Creating a symlink on
Windows needs SeCreateSymbolicLinkPrivilege, which a user without
Developer Mode or elevation lacks, so setUpClass failed with WinError
1314 and select_tests failed on every local Windows run. On that error
the link is now a directory junction, a reparse point realpath resolves
the same way. Where symlinks can be created nothing changes.

Subject: [PATCH 0599/1000] test(agc): require the GPU route for the indirect
 rect-list draws

agc_driver_rect_list_indirect compared the indirect draws' output with
the direct draws only, so it also passed when the records were read on
the CPU. Its records lived in a static array that is not guest memory,
so every indirect draw fell back to the CPU path as not imported.

The records now sit in a registered 64 KiB guest allocation, the test
turns on APS5_PROFILE_DRAW and reads the indirect-draw counters through
the new Graphics::IndirectDrawCounts, and it requires all four indirect
draws on the GPU path. It fails with APS5_NO_RECT_INDIRECT=1 and with
the IndirectDraw.cpp and Draw.cpp changes reverted (4 non-vertex path).

Subject: [PATCH 0600/1000] feat(libc): print the text that registers point at
 in Windows crash reports

Unreal titles end in their own libc fatal path with the UTF-16
LowLevelFatalError message in a register, and the crash report shows
only the first 64 bytes of it as hex words, so the message is lost
(#4238: Demon Slayer PPSA03490, Stray PPSA02100).

For every general register that points at readable memory starting
with at least four printable ASCII characters, as UTF-16LE or as single
bytes, the report now prints the text up to a NUL, the first other
character, 512 characters or the end of readable memory (each page is
checked with VirtualQuery before it is read).

 ### Windows crash diagnostics
 
+When a register points at readable memory that starts with at least four printable ASCII characters, either as UTF-16LE or as single bytes, the crash report prints that text after the register memory dump, as `[r13] u"..."` for UTF-16LE or `[rdi] "..."` for single bytes. The text ends at a NUL, at the first character that is not printable ASCII, a tab, a line feed or a carriage return, after 512 characters or at the end of readable memory. Tabs, line breaks, quotes and backslashes are escaped, and `...` after the closing quote means that no NUL ended the text within those limits.
+
 Set `APS5_CRASH_INDIRECT_MEMORY=1` before launching the executable to include up to 64 bytes from each pointer found in the register memory dump. The report labels each block with its register, pointer offset and target address. Inaccessible, incomplete and executable targets are skipped. This additional dump is disabled when the variable is unset or empty.

 ### Unknown function info
 
-- [libSceVdecsw](../../../core/libs/prx/libSceVdecsw/Export.cpp) (libSceVdecsw) - structure layouts follow shadPS4's `vdecsw.h` and were checked against PPSA05684's movie decoder (`movie-decoder-vdecsw.cpp`), which asserts `pictureCount == 1` at offset 0xb of `OutputInfo` and reads `InputResult` offset 0x10 as the number of frames an access unit produced. The compute, decoder memory and decode input structures and the first 0x28 bytes of the 0x50-byte decoder config are those of libSceVideodec2, and decoding goes through it. The 0x78-byte AVC picture info is filled with Videodec2's leading fields and the cropping fields only.

EA SPORTS FC 27 (PPSA34015) fails to load `libSceNpManager.prx` without it (`unresolved ELF import` / `GetLastError: 127`). Its only call is `mov edi, r14d` (a user id) and `lea rsi, [rbp-0x40]` after a 17-byte copy into that buffer (`mov edx, 0x11`); `test eax, eax` follows. The C name, the type of the 17-byte object and the console return are unknown, so every call throws without reading or writing caller memory
+- [sceNpUnknown_WxLcN76q19o](../../../core/libs/prx/libSceNpManager/Export.cpp) (libSceNpManager, NID `WxLcN76q19o`) - the name is not in aerolib. PPSA34015 imports it from `libSceNpManager.prx` as a strong `JUMP_SLOT` with no call found in the eboot; the loader still requires the export. Arguments, result and console errors are unknown, so every call throws.
 - [sceNpSetTimeout](../../../core/libs/prx/libSceNpManager/Export.cpp) (libSceNpManager) - the signature follows [orbital](https://github.com/AlexAltea/orbital/blob/b321fcdbd700cc02da1cb1ad25412781d5ec73c6/tools/ida/db_types.json), [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/0fe263a4760dfbfa973366890061749b4af0de97/src/core/libraries/np/np_manager.cpp) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Np/NpAccount.cs); the rejected values (all five 0, negative retries, a resolve timeout under 1 s or another timeout under 10 s, 0 meaning the default) are shadPS4's, not checked on a console. An id that was never created or was deleted returns `REQUEST_NOT_FOUND`, as in shadPS4; there is no network, so the timeouts are not stored
 - [sceNpGetUserIdByAccountId](../../../core/libs/prx/libSceNpManager/Export.cpp) - the `(account id, user id output)` signature and its errors follow [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/np/np_manager.cpp): account id 0 or a null output returns `SCE_NP_ERROR_INVALID_ARGUMENT`, and a signed-out NP returns `SCE_NP_ERROR_SIGNED_OUT` without writing the output. NP is always signed out here, so no account id resolves to a user

Subject: [PATCH 0607/1000] fix(agc): give the overlay's view the transfer
 usage of its pass layouts

The overlay's render pass starts in the layout the image was left in and
ends in the one its caller needs next, but the attachment view allowed only
COLOR_ATTACHMENT usage. A pass that starts in TRANSFER_DST_OPTIMAL (the
present path when nothing was drawn, and the tests) or ends in
TRANSFER_SRC_OPTIMAL (the tests' readback) then broke
VUID-vkCmdBeginRenderPass-initialLayout-00898 and -00899. The view now
also allows TRANSFER_DST or TRANSFER_SRC when the pass names that layout.
Swapchain images have TRANSFER_DST and their pass ends in PRESENT_SRC, so
the present path asks only for that; the test's cost report image, whose
pass ends in TRANSFER_SRC_OPTIMAL, is now created with TRANSFER_SRC.

Subject: [PATCH 0608/1000] fix(agc): rasterize a single-sample scan into a
 multisampled depth target at the pixel center

A draw with PA_SC_AA_CONFIG.MSAA_NUM_SAMPLES 0 and MSAA_ENABLE clear
into a 4x depth target threw "the depth target's sample count differs
from the rasterizer's", which stops METAL GEAR SOLID: Peace Walker
(PPSA18216) at its first presentation. Such a draw now rasterizes the
depth target's sample count with every sample at the pixel center, as
a single-sample scan into a multisampled color target already does.
radeonsi programs this MSAA_ENABLE and PA_SC_AA_CONFIG with the depth
buffer's own sample count when GL multisampling is disabled, and GL
then gives full coverage with every depth and stencil sample set from
the pixel center.

Triangles and rectangles are accepted. Points, lines, alpha-to-coverage,
DB_EQAA Z interpolation or overrasterization, a pixel program reading
the sample index and a sample-mask export throw on this path, as does
a single-sample color target next to the multisampled depth target.
The primitive check is shared with the single-sample MSAA_ENABLE rule,
whose behaviour and messages are unchanged.

 - [Multisampled target guest access](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) (libSceAgcDriver) - the memory a multisampled color target throws on (CPU read, DMA copy, texture or storage image read) uses fragment-aware 64 KiB render-target blocks. [AMD Addrlib's GFX10 thin-block rule](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/core/addrlib2.cpp#L1680-L1712) gives the block width and height from element bytes and fragment count; its [surface-size calculation](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp#L4000-L4005) rounds both extents to those blocks and multiplies by element bytes and fragments. Thus a 1920x1080 4x RGBA8 surface occupies 0x1fe0000 bytes, leaving the next allocation at +0x2000000 outside the guard. The 2x and 8x block orientations differ from treating the fragments as a larger element. Console address-layout equivalence has not been measured. Other tile modes retain the conservative `max(CB bytes * samples, width * height * element bytes * samples)` bound, which may still reject a distinct allocation. Targets are kept per device for the device's lifetime, one per surface address, format, extent and sample count, and are not evicted.
 - [CB resolve sample count](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - a draw with CB_COLOR_CONTROL in resolve mode is a CB resolve when either PA_SC_AA_CONFIG or CB_COLOR0_ATTRIB.NUM_SAMPLES is multisampled, and takes its sample count from CB0. Inferred, not from documentation: PPSA36082 resolves its 4x targets with no sample count in PA_SC_AA_CONFIG, and radeonsi sets PA_SC_AA_CONFIG to 0 for a multisampled framebuffer when rasterizer multisampling and line smoothing are off.
 - [Custom MSAA sample locations](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) support a uniform 1x1 pattern for 2, 4 or 8 samples through VK_EXT_sample_locations. Patterns varying across the guest's 2x2 pixel grid use a 2x2 sample location grid, anchored at the framebuffer origin like the guest's while the window offset is zero, on devices whose `maxSampleLocationGridSize` for the sample count is a multiple of 2x2, and throw on others. The RTX 5070 reports 2x4 for 2 samples, 2x2 for 4 and 1x2 for 8; an AMD Radeon integrated GPU reports 2x2 for each. Devices without the required sample count, four subpixel bits or the full guest coordinate range refuse custom patterns. A multisampled rasterizer drawing into one-sample color targets, and a one-sample depth target if any, with MSAA_ENABLE set, no alpha-to-coverage and no coverage pixel input is drawn with one sample at sample 0's location in each pixel of the grid, as the targets keep only sample 0's coverage. Without PS_ITER_SAMPLE such a draw also refuses centroid inputs, and keeps PERSP_SAMPLE, LINEAR_SAMPLE and ANCILLARY: a pixel shaded once is taken to get sample 0's barycentrics and sample index 0. With PS_ITER_SAMPLE only sample 0's invocation reaches the targets, so its sample and centroid barycentrics are taken to be sample 0's and the draw is shaded once. Both are inferred, not measured. ANCILLARY with POS_X_FLOAT or POS_Y_FLOAT throws, since reading the sample index makes the host shade per sample, which moves FragCoord from the pixel center to sample 0's location. By the same Vulkan rule, PERSP_CENTER and LINEAR_CENTER inputs on this path are interpolated at sample 0's location on the host, where the console uses the pixel center; one-sample depth images are created with `SAMPLE_LOCATIONS_COMPATIBLE_DEPTH` when the device supports it, as multisampled ones already were; this is how VK_AMD_mixed_attachment_samples defines the case, and it is not measured on PS5 hardware. Other mixed sample counts throw. Depth images remain in GENERAL between draws, and render passes cannot continue across pattern changes. Guest offsets retain the existing decoder's signed four-bit, sixteenth-pixel interpretation; PS5 coverage and interpolation equivalence have not been measured on hardware.

Subject: [PATCH 0609/1000] docs(agc): cite the GL rule the multisampled depth
 scan follows

The debt entry cited ARB_multisample's centermost-sample shortcut as
what a single-sample scan into a multisampled depth target draws. The
draw tests each depth and stencil sample with the depth at the pixel
center, which is the rule above that shortcut (L185-L190 and
L422-L425); the shortcut is now named as an unmeasured alternative.

 - [Multisampled target guest access](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) (libSceAgcDriver) - the memory a multisampled color target throws on (CPU read, DMA copy, texture or storage image read) uses fragment-aware 64 KiB render-target blocks. [AMD Addrlib's GFX10 thin-block rule](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/core/addrlib2.cpp#L1680-L1712) gives the block width and height from element bytes and fragment count; its [surface-size calculation](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp#L4000-L4005) rounds both extents to those blocks and multiplies by element bytes and fragments. Thus a 1920x1080 4x RGBA8 surface occupies 0x1fe0000 bytes, leaving the next allocation at +0x2000000 outside the guard. The 2x and 8x block orientations differ from treating the fragments as a larger element. Console address-layout equivalence has not been measured. Other tile modes retain the conservative `max(CB bytes * samples, width * height * element bytes * samples)` bound, which may still reject a distinct allocation. Targets are kept per device for the device's lifetime, one per surface address, format, extent and sample count, and are not evicted.
 - [CB resolve sample count](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - a draw with CB_COLOR_CONTROL in resolve mode is a CB resolve when either PA_SC_AA_CONFIG or CB_COLOR0_ATTRIB.NUM_SAMPLES is multisampled, and takes its sample count from CB0. Inferred, not from documentation: PPSA36082 resolves its 4x targets with no sample count in PA_SC_AA_CONFIG, and radeonsi sets PA_SC_AA_CONFIG to 0 for a multisampled framebuffer when rasterizer multisampling and line smoothing are off.
 - [Custom MSAA sample locations](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) support a uniform 1x1 pattern for 2, 4 or 8 samples through VK_EXT_sample_locations. Patterns varying across the guest's 2x2 pixel grid use a 2x2 sample location grid, anchored at the framebuffer origin like the guest's while the window offset is zero, on devices whose `maxSampleLocationGridSize` for the sample count is a multiple of 2x2, and throw on others. The RTX 5070 reports 2x4 for 2 samples, 2x2 for 4 and 1x2 for 8; an AMD Radeon integrated GPU reports 2x2 for each. Devices without the required sample count, four subpixel bits or the full guest coordinate range refuse custom patterns. A multisampled rasterizer drawing into one-sample color targets, and a one-sample depth target if any, with MSAA_ENABLE set, no alpha-to-coverage and no coverage pixel input is drawn with one sample at sample 0's location in each pixel of the grid, as the targets keep only sample 0's coverage. Without PS_ITER_SAMPLE such a draw also refuses centroid inputs, and keeps PERSP_SAMPLE, LINEAR_SAMPLE and ANCILLARY: a pixel shaded once is taken to get sample 0's barycentrics and sample index 0. With PS_ITER_SAMPLE only sample 0's invocation reaches the targets, so its sample and centroid barycentrics are taken to be sample 0's and the draw is shaded once. Both are inferred, not measured. ANCILLARY with POS_X_FLOAT or POS_Y_FLOAT throws, since reading the sample index makes the host shade per sample, which moves FragCoord from the pixel center to sample 0's location. By the same Vulkan rule, PERSP_CENTER and LINEAR_CENTER inputs on this path are interpolated at sample 0's location on the host, where the console uses the pixel center; one-sample depth images are created with `SAMPLE_LOCATIONS_COMPATIBLE_DEPTH` when the device supports it, as multisampled ones already were; this is how VK_AMD_mixed_attachment_samples defines the case, and it is not measured on PS5 hardware. Other mixed sample counts throw. Depth images remain in GENERAL between draws, and render passes cannot continue across pattern changes. Guest offsets retain the existing decoder's signed four-bit, sixteenth-pixel interpretation; PS5 coverage and interpolation equivalence have not been measured on hardware.

PPSA26344's two call sites (`0xE307BF`, `0x151C45D`) pass an allocated pointer, a 0x40000-byte block and app type 0x10000000; the app type and block are not used. The endpoint calls assume the PS4 `libSceVoiceQoS` signatures (`CreateLocalEndpoint(int* id, user, device)`, `DeleteLocalEndpoint(id)`, `CreateRemoteEndpoint(int* id)`, `DeleteRemoteEndpoint(id)`, `Connect(int* id, local, remote)`, `Disconnect(connection)`, `SetLocalEndpointAttribute(id, attribute, value, size)`), not confirmed on a PS5 title. Endpoints and connections are tracked (an endpoint in a connection cannot be deleted, a pair connects once); local endpoint attributes are stored as given, as their ids and defaults are unknown; other endpoint and packet calls remain throwing stubs. The not-initialized error 0x804E0901 is assumed from the 0x804E09xx numbering, and unknown ids return `ARGUMENT_INVALID`. Aliens: Fireteam Elite (PPSA03393) uses all seven implemented calls on its first load path, starting with `sceVoiceQoSCreateLocalEndpoint` when it registers the local talker; it stops with `not implemented` when any of them throws

Subject: [PATCH 0614/1000] fix(agc): pick the overlay's palette entry with
 constant indices

On RADV the overlay's fragment shader read parameters.palette[paletteIndex]
as palette[0] for the text and graph rectangles, so they were drawn in the
panel's colour (0,0,0,0.6) and darkened the panel a second time instead of
drawing white or green. On an AMD Radeon RX 7600 (NAVI33) with Mesa 26.0.8,
agc_performance_overlay failed in its SDR case at "'6' of 'FPS: 60.0' glyph
pixel 2,0 is not white text: 0x4280161290": 0xff1e140a is the clear colour
(191,128,64) darkened by 0.4 twice, where the panel alone gives 0xff4c331a.
An integrated Radeon 660M failed at the full panel's first glyph.

The shader was valid SPIR-V: a flat uint input indexing a push-constant
array (the palette at offset 0, the extent at 48). The index is per
rectangle, and fragments of the panel and of its glyphs share waves, so it
varies within a wave; RADV read that divergent index into the push-constant
array as 0. The shader now reads each entry at a constant index and selects
one by the colour index. Every case passes on that RX 7600 with this change,
full panel included, and still passes on llvmpipe from the same Mesa.

Subject: [PATCH 0615/1000] fix(libc): catch exceptions that libstdc++ throws
 inside the prx libraries on Linux

The nid_patcher turns each *_nid_no_patch_cut alias into a second dynamic
symbol with the same name as the plain alias exported next to it, seven
names in all. With those duplicates, LD_DEBUG=bindings shows libstdc++ keeping its own __cxa_allocate_exception, __cxa_throw,
__cxa_begin_catch, __cxa_end_catch, __cxa_rethrow, __gxx_personality_v0
and _Unwind_Resume while taking __cxa_init_primary_exception,
_Unwind_RaiseException and std::terminate from libc.prx. An exception
thrown inside libstdc++ (std::stoi, a stream with exceptions enabled) got
a libc header laid over a libstdc++ allocation, reached the libc
personality as a foreign exception, matched no typed handler and ended in
"terminate called without an active exception". The plain aliases already
export these names, so the duplicates go.

libstdc++ also describes std::__ios_failure with __iosfail_type_info, a
class that privately derives from __si_class_type_info at the same
address. Kind now follows such single same-address bases to the
__cxxabiv1 class, so catching std::ios_base::failure or std::exception
matches a stream failure.

The plain aliases came in a4c519b26 next to the cut aliases from
14f8c16ac.

Subject: [PATCH 0616/1000] perf(recompiler): select guest memory loads instead
 of branching around them

LDS, scratch and direct storage-buffer loads load element 0 when the lane is
inactive or the address is out of bounds and select 0 as the result, instead of
opening a selection per guard. Stores, atomics, formatted and physical-address
accesses keep their branches. A branch guard cost four blocks per lane half, and
the host compiler's time grows with the block count: PPSA11142's merged PSP
vertex program emitted 16,983 blocks and 1,710 conditional branches, 5,907 and
868 with the selects.

 - [Flag structurization](../../../core/shader/recompiler/ControlFlow/src/Structurizer.cpp) (shader recompiler) - a graph that every structurizer attempt refuses, irreducible and non-terminating graphs included, is rebuilt with one reach flag per block and one again flag per loop (`structurizeWithFlags`): each block keeps one copy and runs behind a guard on its flag, and each strongly connected component becomes a loop whose single latch repeats it while a back edge set its flag. The output has about 8 times the input's blocks and one route variable per block, and ends in an empty Return that never runs. Only blocks that start the top-level order unconditionally run unguarded, so resource planning also sees the static paths that skip a guarded block and can plan extra descriptor candidates for them. The attempts still run first. Shared merge splitting refuses an attempt once the graph has grown past 16 times its block count at the start of splitting (at least 64 blocks); succeeding attempts grew at most 10.6 times on random graphs of up to 128 blocks, and an attempt that would succeed only beyond the budget leaves the graph to a later attempt or to this construction. Splitting that adds one block per round stays within that budget until its 4 rounds per block run out, so the attempts can still take more than 10 s (9 of 2,000 random graphs of up to 128 blocks, 63 s at most). `APS5_FORCE_STRUCTURIZER_FALLBACK=1` builds every graph this way, for tests
 - [Scalar buffer descriptors](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) use only the base address, stride and record count for resources accessed exclusively by scalar loads; their fourth word is normalized to zero, following AMD RDNA2 ISA section 7.2.2. Vector and mixed accesses retain descriptor validation. Native Vulkan readbacks cover ignored fourth-word fields on Windows/NVIDIA; their console behavior has not been measured.
 - [Spanned wave64 compute](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvSubgroup.cpp) (shader recompiler) - `APS5_SPANNED_WAVE=1`, off by default, runs a single-wave wave64 compute program at one lane per invocation on a 32-lane host subgroup and exchanges ballots, shuffles and reductions between the two host subgroups through workgroup memory and barriers. The driver turns it on only where compute subgroups can be pinned at 32 full lanes (`subgroupSizeControl` and `computeFullSubgroups`), passes it as `SpirvTarget::spannedWaves` (part of the cache key and the serialized request), and creates the pipelines of spanned programs with `REQUIRE_FULL_SUBGROUPS`, since the lane number `SubgroupId * 32 + SubgroupLocalInvocationId` needs two full subgroups. Those barriers are correct only where every invocation of the workgroup reaches them, which holds for the guest's wave-uniform control flow. The emulated 64-bit LDS atomics ([LockedLdsUpdate](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp)) run only on the lanes the exec mask keeps, so their lock loop ballots within its own host subgroup, as its elect already does. Any other cross-lane exchange emitted inside per-lane control flow would hang a spanned wave in the same way, and the emitter does not reject one: there is no uniformity check. The only check so far is manual: disassemble the module (`spirv-dis`), list the selection and loop constructs that enclose each `OpControlBarrier`, and read the condition of each enclosing selection. In Ghost of Yōtei's program 0x80003af600 (PPSA26344), 108 of 111 barriers sat only in loops on wave-uniform conditions and 3 inside per-invocation conditionals, all in the lock loop. Other programs and titles have not been scanned. An earlier, cheaper ballot (one barrier instead of three) also lost the device for a reason that is not understood, which may be another barrier placement problem. Measured on an RTX 4090 (Windows): an offline replay of that program and two Yōtei runs that previously lost the device (NVIDIA TDR) now run past it, and [LdsMaskWaterfall.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/LdsMaskWaterfall.cpp) runs both modes and covers a half-inactive wave. Stray (PPSA02101) on Intel ANV and a Demon's Souls (PPSA01342) request replay showed no fault, before this fix
+- [Guest memory load guards](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - LDS, scratch and direct storage-buffer loads (`LoadWord`, `LoadSubword`, `LoadWideShared`, `readBuffer` and `EmitRuntimeScalarBufferLoad` in [SpirvRuntimeBuffer.cpp](../../../core/shader/recompiler/SpirvBackend/src/SpirvRuntimeBuffer.cpp)) load element 0 when the lane is inactive or the address is out of bounds and select 0 as the result, instead of branching around the load; stores, atomics, formatted and physical-address (BDA) accesses still branch. A branch guard costs four blocks per lane half and the host compiler's time grows with the block count: PPSA11142's merged PSP vertex program (3176 ISA words, wave64) emitted 16,983 blocks and 1,710 conditional branches, 5,907 and 868 with the selects. The unconditional load depends on element 0 being addressable: SPIR-V function and workgroup arrays have at least one element, and a storage buffer with no elements reads out of bounds, which is defined only with `robustBufferAccess` ([VulkanDevice.cpp](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) enables it when the device has it).

Subject: [PATCH 0617/1000] fix(recompiler): point selected guest loads at
 locations nothing writes

A load selected instead of branched still accesses memory, so its fallback
element must be one no write can race with: scratch keeps element 0, LDS in
workgroup or function memory reads a sentinel dword appended after the
program's LDS and lock, and storage buffers read element 0xfffffffe, which
robustBufferAccess2 turns into a zero load without a memory access. The
device enables robustBufferAccess2 when it has it and the target carries the
flag; without it, and for LDS in device memory, buffer loads keep their
selections. The aligned high word of a buffer read re-reads the low word's
element instead of word 0. agc_guarded_memory_loads traces the emitted loads
in both device modes.

 - [Scalar buffer descriptors](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) use only the base address, stride and record count for resources accessed exclusively by scalar loads; their fourth word is normalized to zero, following AMD RDNA2 ISA section 7.2.2. Vector and mixed accesses retain descriptor validation. Native Vulkan readbacks cover ignored fourth-word fields on Windows/NVIDIA; their console behavior has not been measured.
 - [Spanned wave64 compute](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvSubgroup.cpp) (shader recompiler) - `APS5_SPANNED_WAVE=1`, off by default, runs a single-wave wave64 compute program at one lane per invocation on a 32-lane host subgroup and exchanges ballots, shuffles and reductions between the two host subgroups through workgroup memory and barriers. The driver turns it on only where compute subgroups can be pinned at 32 full lanes (`subgroupSizeControl` and `computeFullSubgroups`), passes it as `SpirvTarget::spannedWaves` (part of the cache key and the serialized request), and creates the pipelines of spanned programs with `REQUIRE_FULL_SUBGROUPS`, since the lane number `SubgroupId * 32 + SubgroupLocalInvocationId` needs two full subgroups. Those barriers are correct only where every invocation of the workgroup reaches them, which holds for the guest's wave-uniform control flow. The emulated 64-bit LDS atomics ([LockedLdsUpdate](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp)) run only on the lanes the exec mask keeps, so their lock loop ballots within its own host subgroup, as its elect already does. Any other cross-lane exchange emitted inside per-lane control flow would hang a spanned wave in the same way, and the emitter does not reject one: there is no uniformity check. The only check so far is manual: disassemble the module (`spirv-dis`), list the selection and loop constructs that enclose each `OpControlBarrier`, and read the condition of each enclosing selection. In Ghost of Yōtei's program 0x80003af600 (PPSA26344), 108 of 111 barriers sat only in loops on wave-uniform conditions and 3 inside per-invocation conditionals, all in the lock loop. Other programs and titles have not been scanned. An earlier, cheaper ballot (one barrier instead of three) also lost the device for a reason that is not understood, which may be another barrier placement problem. Measured on an RTX 4090 (Windows): an offline replay of that program and two Yōtei runs that previously lost the device (NVIDIA TDR) now run past it, and [LdsMaskWaterfall.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/LdsMaskWaterfall.cpp) runs both modes and covers a half-inactive wave. Stray (PPSA02101) on Intel ANV and a Demon's Souls (PPSA01342) request replay showed no fault, before this fix
 - [Guest memory load guards](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - LDS, scratch and direct storage-buffer loads (`LoadWord`, `LoadSubword`, `LoadWideShared`, `readBuffer` and `EmitRuntimeScalarBufferLoad` in [SpirvRuntimeBuffer.cpp](../../../core/shader/recompiler/SpirvBackend/src/SpirvRuntimeBuffer.cpp)) load element 0 when the lane is inactive or the address is out of bounds and select 0 as the result, instead of branching around the load; stores, atomics, formatted and physical-address (BDA) accesses still branch. A branch guard costs four blocks per lane half and the host compiler's time grows with the block count: PPSA11142's merged PSP vertex program (3176 ISA words, wave64) emitted 16,983 blocks and 1,710 conditional branches, 5,907 and 868 with the selects. The unconditional load depends on element 0 being addressable: SPIR-V function and workgroup arrays have at least one element, and a storage buffer with no elements reads out of bounds, which is defined only with `robustBufferAccess` ([VulkanDevice.cpp](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) enables it when the device has it).
+- [Guest memory load guards](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - a guest load whose lane is inactive or whose address is out of bounds is still performed and its result replaced by 0 with `OpSelect`, instead of a selection per guard, when the load can be pointed at a location nothing writes: scratch reads its own element 0; LDS in workgroup or function memory reads a sentinel dword appended after the program's LDS (and after the lock dword), which no bounds-checked write reaches; storage buffers (direct buffers, GDS) read element 0xfffffffe, which `robustBufferAccess2` turns into a zero load with no memory access, so the extra read cannot race with a write the guarded program would not have raced with ([Vulkan memory model](https://docs.vulkan.org/spec/latest/appendices/memorymodel.html#data-race)). Without `robustBufferAccess2` ([VulkanDevice.cpp](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) enables it when the device has it), and for LDS kept in device memory, those loads keep their selections; stores, atomics, formatted and physical-address (BDA) accesses always do. The aligned high word of a misaligned-capable buffer read re-reads the low word's own element. A selection guard costs four blocks per lane half and the host compiler's time grows with the block count: PPSA11142's merged PSP vertex program (3176 ISA words, wave64) emitted 16,983 blocks and 1,710 conditional branches, 5,907 and 868 with the selects. `agc_guarded_memory_loads` traces the emitted loads in both device modes.

Subject: [PATCH 0621/1000] perf(recompiler): keep LDS loads branched and drop
 the LDS sentinel

NVIDIA's compiler predicates a branched LDS load at no cost, while the
selected form costs about 2.5 instructions per dword and splits a
ds_read_b128 into four loads (RTX 4060 measurements by @karanvora2599 in
loads therefore keep the branch of main, in workgroup, function and device
memory alike, and the sentinel dword that only they read goes away: the LDS
array is the program's dwords plus the lock again, and the device-memory
decision reserves the lock alone. The sentinel budget tests become lock
budget tests at that boundary, and the guarded-load test pins the branch.

 - [Flag structurization](../../../core/shader/recompiler/ControlFlow/src/Structurizer.cpp) (shader recompiler) - a graph that every structurizer attempt refuses, irreducible and non-terminating graphs included, is rebuilt with one reach flag per block and one again flag per loop (`structurizeWithFlags`): each block keeps one copy and runs behind a guard on its flag, and each strongly connected component becomes a loop whose single latch repeats it while a back edge set its flag. The output has about 8 times the input's blocks and one route variable per block, and ends in an empty Return that never runs. Only blocks that start the top-level order unconditionally run unguarded, so resource planning also sees the static paths that skip a guarded block and can plan extra descriptor candidates for them. The attempts still run first. Shared merge splitting refuses an attempt once the graph has grown past 16 times its block count at the start of splitting (at least 64 blocks); succeeding attempts grew at most 10.6 times on random graphs of up to 128 blocks, and an attempt that would succeed only beyond the budget leaves the graph to a later attempt or to this construction. Splitting that adds one block per round stays within that budget until its 4 rounds per block run out, so the attempts can still take more than 10 s (9 of 2,000 random graphs of up to 128 blocks, 63 s at most). `APS5_FORCE_STRUCTURIZER_FALLBACK=1` builds every graph this way, for tests
 - [Scalar buffer descriptors](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) use only the base address, stride and record count for resources accessed exclusively by scalar loads; their fourth word is normalized to zero, following AMD RDNA2 ISA section 7.2.2. Vector and mixed accesses retain descriptor validation. Native Vulkan readbacks cover ignored fourth-word fields on Windows/NVIDIA; their console behavior has not been measured.
 - [Spanned wave64 compute](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvSubgroup.cpp) (shader recompiler) - `APS5_SPANNED_WAVE=1`, off by default, runs a single-wave wave64 compute program at one lane per invocation on a 32-lane host subgroup and exchanges ballots, shuffles and reductions between the two host subgroups through workgroup memory and barriers. The driver turns it on only where compute subgroups can be pinned at 32 full lanes (`subgroupSizeControl` and `computeFullSubgroups`), passes it as `SpirvTarget::spannedWaves` (part of the cache key and the serialized request), and creates the pipelines of spanned programs with `REQUIRE_FULL_SUBGROUPS`, since the lane number `SubgroupId * 32 + SubgroupLocalInvocationId` needs two full subgroups. Those barriers are correct only where every invocation of the workgroup reaches them, which holds for the guest's wave-uniform control flow. The emulated 64-bit LDS atomics ([LockedLdsUpdate](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp)) run only on the lanes the exec mask keeps, so their lock loop ballots within its own host subgroup, as its elect already does. Any other cross-lane exchange emitted inside per-lane control flow would hang a spanned wave in the same way, and the emitter does not reject one: there is no uniformity check. The only check so far is manual: disassemble the module (`spirv-dis`), list the selection and loop constructs that enclose each `OpControlBarrier`, and read the condition of each enclosing selection. In Ghost of Yōtei's program 0x80003af600 (PPSA26344), 108 of 111 barriers sat only in loops on wave-uniform conditions and 3 inside per-invocation conditionals, all in the lock loop. Other programs and titles have not been scanned. An earlier, cheaper ballot (one barrier instead of three) also lost the device for a reason that is not understood, which may be another barrier placement problem. Measured on an RTX 4090 (Windows): an offline replay of that program and two Yōtei runs that previously lost the device (NVIDIA TDR) now run past it, and [LdsMaskWaterfall.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/LdsMaskWaterfall.cpp) runs both modes and covers a half-inactive wave. Stray (PPSA02101) on Intel ANV and a Demon's Souls (PPSA01342) request replay showed no fault, before this fix
-- [Guest memory load guards](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - LDS, scratch and direct storage-buffer loads (`LoadWord`, `LoadSubword`, `LoadWideShared`, `readBuffer` and `EmitRuntimeScalarBufferLoad` in [SpirvRuntimeBuffer.cpp](../../../core/shader/recompiler/SpirvBackend/src/SpirvRuntimeBuffer.cpp)) load element 0 when the lane is inactive or the address is out of bounds and select 0 as the result, instead of branching around the load; stores, atomics, formatted and physical-address (BDA) accesses still branch. A branch guard costs four blocks per lane half and the host compiler's time grows with the block count: PPSA11142's merged PSP vertex program (3176 ISA words, wave64) emitted 16,983 blocks and 1,710 conditional branches, 5,907 and 868 with the selects. The unconditional load depends on element 0 being addressable: SPIR-V function and workgroup arrays have at least one element, and a storage buffer with no elements reads out of bounds, which is defined only with `robustBufferAccess` ([VulkanDevice.cpp](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) enables it when the device has it).
-- [Guest memory load guards](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - a guest load whose lane is inactive or whose address is out of bounds is still performed and its result replaced by 0 with `OpSelect`, instead of a selection per guard, when the load can be pointed at a location nothing writes: scratch reads its own element 0; LDS in workgroup or function memory reads a sentinel dword appended after the program's LDS (and after the lock dword), which no bounds-checked write reaches; storage buffers (direct buffers, GDS) read element 0xfffffffe, which `robustBufferAccess2` turns into a zero load with no memory access, so the extra read cannot race with a write the guarded program would not have raced with ([Vulkan memory model](https://docs.vulkan.org/spec/latest/appendices/memorymodel.html#data-race)). Without `robustBufferAccess2` ([VulkanDevice.cpp](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) enables it when the device has it), and for LDS kept in device memory, those loads keep their selections; stores, atomics, formatted and physical-address (BDA) accesses always do. The aligned high word of a misaligned-capable buffer read re-reads the low word's own element. A selection guard costs four blocks per lane half and the host compiler's time grows with the block count: PPSA11142's merged PSP vertex program (3176 ISA words, wave64) emitted 16,983 blocks and 1,710 conditional branches, 5,907 and 868 with the selects. `agc_guarded_memory_loads` traces the emitted loads in both device modes.

Subject: [PATCH 0623/1000] fix(libSceRazorCpu): add sceRazorCpuNamedSync
 export

Resolve the XCuZoBSVFG8 import required by Killzone Liberation by adding sceRazorCpuNamedSync as a no-op returning success when capture is inactive.

Extend the RazorCpu behavior test and document the NID source and unverified console signature and capture behavior.

Subject: [PATCH 0625/1000] fix(tests): end Windows test processes through libc
 before DLL detach

On Windows a test that returns from main ends through exit and ExitProcess,
which kills every other thread before the prx static destructors run at
DLL_PROCESS_DETACH. Detached host threads (the driver's async log thread,
libkernel's file watch thread, ...) die holding winpthreads and queue locks,
and a destructor that then locks a mutex, waits for the dead logger or
destroys a condition variable never returns: the test prints its last line
and hangs until the CTest timeout (#6791).

Every test executable now wraps main on MinGW. After main returns the
wrapper runs the executable's own exit handlers and static destructors
(_cexit), as exit does today, flushes the streams and ends the process with
LibcTerminate_nid_no_patch, the path the guest exit already takes. That
flushes the driver log while its thread is alive and calls TerminateProcess,
so no DLL_PROCESS_DETACH work runs after the threads are gone. The libc
shutdown callbacks are not run, as on a plain return from main on Linux. A
test that does not load libc.prx returns as before.

Subject: [PATCH 0626/1000] feat(libkernel): read param.sfo when param.json is
 absent

PS4 titles ship sce_sys/param.sfo instead of param.json. When param.json
is absent, the application metadata now reads the title, title ID,
download data size and user defined parameters from param.sfo, and
/data and /download0 are mounted for it as for param.json. param.json
is still preferred when both files exist.

 - [rtprio_thread, pthread_setconcurrency, pthread_getconcurrency](../../../core/libs/prx/libkernel/Pthread/Posix/Thread.cpp) (libkernel) - `rtprio_thread` follows FreeBSD 11.4's `rtprio_thread(2)`. Every guest thread here runs under `SCHED_FIFO` or `SCHED_RR` (priority 256-767), whose rtprio class is real-time; the console's mapping from that priority to the rtprio `prio` range (0-31) is unmeasured, so `RTP_LOOKUP` and `RTP_SET` throw for such a thread rather than report an impossible priority. A thread that is not real-time reports `RTP_PRIO_NORMAL` (3) with 0, and `RTP_SET` accepts only that value. Another function fails with `EINVAL`, a null `rtprio` with `EFAULT`, a thread other than the calling one throws, and an id that is not a live guest thread with `ESRCH`. `pthread_setconcurrency` stores 0 or more and returns `EINVAL` for a negative level (the error itself, as FreeBSD's libthr does, with errno untouched); `pthread_getconcurrency` returns the level, which is a hint and changes nothing about the host's concurrency. Morrowind (`mshivam019/morrowind-ps5`) imports all three at start-up
 - [sceKernelVirtualQuery](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) returns [VirtualQueryInfo](../../../core/libs/SceTypes.hpp) with a one-byte flag allocation unit so Windows and SysV hosts return the same 72-byte representation, with the name at byte 33 and GPU mask at byte 65. This preserves the existing SysV representation; the console offsets beyond the address, protection and size fields observed in Astro Bot's AGC calls are not hardware-measured. Size and offset assertions plus a raw-byte named-mapping regression guard the host ABI.
 - [app0.zar files](../../../core/libs/prx/libkernel/File/src/ArchivedFile.cpp) (libkernel) - `sceKernelOpen`, `open`, `sceKernelStat` and `sceKernelCheckReachability` resolve a path missing from `app0/` in `app0.zar`. An archived file is a read-only host null device whose reads, positioned and vectored reads, AIO reads, seeks, `fstat` and `FIONREAD` are served from the archive, with the position shared by `dup`, `dup2` and `F_DUPFD`; writes fail with `EBADF` as on a read-only descriptor, opening one for writing or truncation fails with `EROFS` and `O_CREAT | O_EXCL` with `EEXIST`. `fstat` and `sceKernelStat` report mode `0444` (`0555` for a directory), the node index as inode and the archive file's device and times. Opening an archived directory or a directory present both on disk and in the archive throws, as `getdents` would miss entries. On an archived descriptor `mmap`, `flock`, record locks, `fstatfs`, `ftruncate`, `fsync`, `fdatasync`, `getdirentries`, `fchmod` and `futimes` throw instead of acting on the null device; `mmap` is `noexcept`, so its refusal terminates the process. `lstat` and the other path calls on archived files are not implemented
+- [param.sfo](../../../core/libs/prx/libkernel/AppMetadata/src/ParamSfoParser.cpp) (libkernel) is read when `param.json` is absent, for `TITLE`, `TITLE_ID`, `DOWNLOAD_DATA_SIZE` and `USER_DEFINED_PARAM_1` to `_4`, and mounts `/data` and `/download0` like `param.json`; the localized `TITLE_00` to `TITLE_30` are not selected by the console language.

Subject: [PATCH 0628/1000] feat(libkernel): serve the console CA list from the
 host trust store

Titles that bundle OpenSSL load the console's CA file from the sandbox
directory and fail every HTTPS request without it. ProsperoRadio
(PPSA99001, libcurl 8.18.0 + OpenSSL 3.5.2) on main + #4796 + #4525:

  [ProsperoRadio][http] https://all.api.radio-browser.info/json/servers: Problem with the SSL CA cert (path? access rights?) (error adding trust anchors from file: /gkbHtXc3Wq/common/cert/CA_LIST.cer)

SwanStation (PPSA98510) stops on the same file (#5001).

The guest path resolver now accepts exact-path providers, and libkernel
registers one for /<sceKernelGetFsSandboxRandomWord()>/common/cert/CA_LIST.cer.
On first use it writes a PEM bundle once per process to
cert_cache/CA_LIST.cer in the run directory, read-only: on Windows the
current user's ROOT and CA system stores, elsewhere SSL_CERT_FILE or the
first distro bundle that exists. Without a certificate the path keeps
resolving under the guest root and does not exist, as before. Every other
path under the sandbox word is unchanged. The console file's format and
the rest of its common/cert directory are unverified and recorded in
docs/dev/debt/libkernel.md.

With this change, #4796, #4525 and #5025 on Windows 11, 60 s each:

 - [sceKernelPread, sceKernelPwrite, sceKernelPreadv, sceKernelPwritev](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on Windows transfer at the given offset with an overlapped `ReadFile`/`WriteFile` and restore the descriptor's file pointer afterwards. Guest scalar transfers, positioned transfers, vectored transfers and seeks share a position lock across duplicated descriptors; a vector holds it for the whole operation. Independently opened descriptors and other processes do not share that lock, so vector transfers over their overlapping file ranges are not coordinated. Handles that are not disk files return `ESPIPE`. A pipe or console `readv` can return a short read when no more input is available; each iovec is transferred separately, so a failure after the first transfer returns the bytes already done
 - [sceKernelAioSubmitReadCommands, sceKernelAioSubmitWriteCommands and their Multiple variants](../../../core/libs/prx/libkernel/Aio/src/Aio.cpp) (libkernel) on Windows transfer through the same positioned path as `sceKernelPread`/`sceKernelPwrite` and restore the descriptor's file pointer afterwards; positioned transfers, plain transfers and seeks of one descriptor are serialized per descriptor (shared across duplicated descriptors), so a concurrent transfer observes a stable file pointer
 - [sceKernelAioSetParam](../../../core/libs/prx/libkernel/Aio/src/Aio.cpp) (libkernel) writes the five values into the 20-byte scheduling struct the first argument points to, following the declarations in [Orbital](https://github.com/AlexAltea/orbital/blob/cc408367da6a6ebbf5ac1ac559fefeadc73b2831/tools/ida/db_types.json), [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Kernel/KernelAio.cs) and [ampr_emu](https://github.com/drakmor/ampr_emu/blob/cfa85df379f6eeeb165d7badf9b648e266fe77b7/ps5/include/sce/_fs.h). Whether the console checks the values is unknown, so a null struct, a scheduling window or delayed count limit outside 0..128, a split flag other than 0 or 1 and a split size or chunk size above 0x1000000 (SharpProspero's maximums) throw. The scheduling settings are not used: `sceKernelAioInitializeImpl` ignores the struct and requests run synchronously on submit
-- [sceKernelGetFsSandboxRandomWord](../../../core/libs/prx/libkernel/System/src/Sandbox.cpp) (libkernel) returns a fixed directory name, `gkbHtXc3Wq`. On the console the name is the process's randomized path (syscall 602, `randomized_path`), and the sandbox exposes system files under it, such as `common/lib` and `common/cert`. Nothing is mounted under the name here, so `/gkbHtXc3Wq/common/...` resolves under the guest root like any other path and does not exist
+- [sceKernelGetFsSandboxRandomWord](../../../core/libs/prx/libkernel/System/src/Sandbox.cpp) (libkernel) returns a fixed directory name, `gkbHtXc3Wq`. On the console the name is the process's randomized path (syscall 602, `randomized_path`), and the sandbox exposes system files under it, such as `common/lib` and `common/cert`. Nothing is mounted under the name here, so `/gkbHtXc3Wq/common/...` resolves under the guest root like any other path and does not exist, except `/gkbHtXc3Wq/common/cert/CA_LIST.cer`, which [SandboxCertificates.cpp](../../../core/libs/prx/libkernel/File/src/SandboxCertificates.cpp) serves from the host trust store
+- [The sandbox CA list](../../../core/libs/prx/libkernel/File/src/SandboxCertificates.cpp) (libkernel), `/<sandbox word>/common/cert/CA_LIST.cer`, is a PEM bundle of the host's trust anchors, written once per process to `cert_cache/CA_LIST.cer` in the run directory with the owner write bit cleared: on Windows the certificates of the current user's `ROOT` and `CA` system stores (Windows fetches missing roots on demand, so a root that was never fetched is absent), elsewhere `SSL_CERT_FILE` or the first of `/etc/ssl/certs/ca-certificates.crt`, `/etc/pki/tls/certs/ca-bundle.crt` and `/etc/ssl/ca-bundle.pem` that exists. Without any certificate the path does not exist. The console file's format is unverified: only that bundled OpenSSL accepts a PEM bundle there is shown (ProsperoRadio PPSA99001 and SwanStation PPSA98510, #5001). The other entries of the console's `common/cert` directory, the directory itself (it does not exist here) and the error a write open gets (`EACCES` from the host here) are unverified
 - [getcontext and setcontext](../../../core/libs/prx/libkernel/System/src/UserContext.cpp) (libkernel) and [makecontext](../../../core/libs/prx/libSceLibcInternal/UserContext.cpp) (libSceLibcInternal) use FreeBSD 11's amd64 `ucontext_t` (`mcontext` at 0x10, `mc_len` 800, `uc_link` at 0x330, `uc_stack` at 0x338, 0x370 bytes), the layout homebrew built against FreeBSD's headers passes: PPSA99039's OpenSSL `ASYNC` (`crypto/async/arch/async_posix.c`) captures into a 0x370-byte stack buffer. `getcontext` writes the 0x330 bytes before `uc_link`, as FreeBSD's `UC_COPY_SIZE`. The console's own layout for these functions is not verified; the exception handler's context is a different one (see `sceKernelRaiseException`)
 - [getcontext and setcontext](../../../core/libs/prx/libkernel/System/src/UserContext.cpp) (libkernel) keep the 512-byte FXSAVE image in `mc_fpstate` (x87, MXCSR, XMM0-15), so the upper halves of YMM0-15 are neither saved nor restored, and `getcontext` leaves `mc_xfpustate` and `mc_xfpustate_len` 0. `getcontext` sets `mc_fpformat` and `mc_ownedfp` to FreeBSD's `_MC_FPFMT_XMM` and `_MC_FPOWNED_FPU`, `mc_cs` and `mc_ss` to the host selectors, and `mc_flags`, `mc_fsbase` and `mc_gsbase` to 0. `setcontext` loads `mc_fpstate` whatever `mc_fpformat` and `mc_ownedfp` say, and restores neither the segment selectors, `mc_fsbase` and `mc_gsbase` nor the extended state, which FreeBSD restores when `mc_flags` asks for them
 - [setcontext](../../../core/libs/prx/libkernel/System/src/UserContext.cpp) (libkernel) and [longjmp](../../../core/libs/prx/libc/src/JumpBuffer.cpp) (libc) on Windows set the thread's stack bounds in the TEB to the stack they switch to: a `makecontext` stack, or else the committed region around the target stack pointer. A switch to any other guest stack, such as a context built by hand, gets the bounds of that region only

On the console the name is the process's randomized path (syscall 602, `randomized_path`), and the sandbox exposes system files under it, such as `common/lib` and `common/cert`. Nothing is mounted under the name here, so `/gkbHtXc3Wq/common/...` resolves under the guest root like any other path and does not exist, except `/gkbHtXc3Wq/common/cert/CA_LIST.cer`, which [SandboxCertificates.cpp](../../../core/libs/prx/libkernel/File/src/SandboxCertificates.cpp) serves from the host trust store

Subject: [PATCH 0630/1000] test(agc): map GPU memory on fibers with and
 without a host stack

Since #6003 a fiber with a context of 64 KiB or more runs on the
context itself, so the 64 KiB fiber of agc_driver_gpu_map_on_fiber
imports its mapping on a host thread on Windows too, and the test's
Windows-only expectation of no thread failed. The test now also maps
on a 16 KiB fiber, which keeps a host stack and imports on it on
Windows, and expects one import thread for the 64 KiB fiber on every
platform.

Subject: [PATCH 0635/1000] fix(recompiler): hold 32 samplers in the runtime
 sampler heap

A pixel shader of PPSA16833 binds more than 16 samplers outside the
sampler tables. Each takes two heap entries, one per descriptor variant,
so the 32-entry heap refused it with "shader sampler pairs exceed runtime
heap capacity" and the title aborted when a new game started.

The heap now holds 64 entries (32 samplers). Its metadata array is part
of ShaderData, which grows from 14528 to 16064 bytes, still within the
16 KiB uniform buffer every Vulkan device supports; the runtime ABI
version moves to 13 so shaders cached with the old layout are rebuilt.
The overflow message names the sampler count.

 - [Multisampled color fills](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) (libSceAgcDriver) - a multisampled target's samples are on the host, so a fill of its color memory is applied at its next use: a uniform fill over the whole of it clears the host image to that value, and a pending CMASK fast clear takes precedence over the fill and over a fill that would throw. Its color memory is a single mip and slice of addrlib's block dimensions for its sample count (ComputeThinBlockDimension). A fill over part of it, a fill reaching the start of a target whose footprint is not computed (linear), and a fill value with no exact clear value in the format (sRGB channels other than 0 and 1) throw at the next use. A fill before the target's first use is not seen (the host image starts at 0), nor are copies or shader writes into its color memory. A uniform compute fill over exactly the whole color memory with an exact clear value is not stored into guest memory, since only the host image holds the samples. A target is retired only when its whole guarded range is unmapped or its allocation removed, so if a title reuses that memory for other data while it stays mapped, a read the guard does not check (a buffer read through a V# or a pointer) sees the bytes from before the fill.
 - [Multisampled texture no draw rendered to](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) (libSceAgcDriver) - sampling a multisampled texture whose surface no draw rendered to creates the host target from the T# and clears it to the color a single 32-bit value repeated over the whole footprint encodes, padding up to whole tile blocks included. Inferred, not measured on the console: that the samples of such a surface are the guest color memory, as a title that clears its canvas on the CPU (ps5-opengl `ps5_clear_msaa4_color`) relies on. Memory that is not one repeated value, tile modes other than Standard4KB, Standard64KB and RenderTarget, unmapped memory and values with no exact clear color throw. CPU writes to the surface after its host target exists are not seen by the host.
 - [Multisampled targets in CB passes](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - a CB eliminate or DCC pass over a multisampled target throws, since its texels are on the host and only a CB resolve and an FMASK decompress (`CB_COLOR_CONTROL` mode 5) are modeled. The FMASK decompress only applies the pending CMASK fast clear to the host image; it requires a CMASK address, and the target's DCC and FMASK contents are not interpreted. DCC over a multisampled target is accepted only in that pass and throws everywhere else. A CB resolve into a fast-clear destination throws: the resolve writes the destination's texels but not its CMASK, which would still read as cleared.
-- [Multisampled target guest access](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) (libSceAgcDriver) - the memory a multisampled color target throws on (CPU read, index buffer read, DMA copy, texture or storage image read) uses fragment-aware 64 KiB render-target blocks. [AMD Addrlib's GFX10 thin-block rule](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/core/addrlib2.cpp#L1680-L1712) gives the block width and height from element bytes and fragment count; its [surface-size calculation](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp#L4000-L4005) rounds both extents to those blocks and multiplies by element bytes and fragments.

 - [CB resolve sample count](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - a draw with CB_COLOR_CONTROL in resolve mode is a CB resolve when either PA_SC_AA_CONFIG or CB_COLOR0_ATTRIB.NUM_SAMPLES is multisampled, and takes its sample count from CB0. Inferred, not from documentation: PPSA36082 resolves its 4x targets with no sample count in PA_SC_AA_CONFIG, and radeonsi sets PA_SC_AA_CONFIG to 0 for a multisampled framebuffer when rasterizer multisampling and line smoothing are off.
 - [Custom MSAA sample locations](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) support a uniform 1x1 pattern for 2, 4 or 8 samples through VK_EXT_sample_locations. Patterns varying across the guest's 2x2 pixel grid use a 2x2 sample location grid, anchored at the framebuffer origin like the guest's while the window offset is zero, on devices whose `maxSampleLocationGridSize` for the sample count is a multiple of 2x2, and throw on others. The RTX 5070 reports 2x4 for 2 samples, 2x2 for 4 and 1x2 for 8; an AMD Radeon integrated GPU reports 2x2 for each. Devices without the required sample count, four subpixel bits or the full guest coordinate range refuse custom patterns. A multisampled rasterizer drawing into one-sample color targets, and a one-sample depth target if any, with MSAA_ENABLE set, no alpha-to-coverage and no coverage pixel input is drawn with one sample at sample 0's location in each pixel of the grid, as the targets keep only sample 0's coverage. Without PS_ITER_SAMPLE such a draw also refuses centroid inputs, and keeps PERSP_SAMPLE, LINEAR_SAMPLE and ANCILLARY: a pixel shaded once is taken to get sample 0's barycentrics and sample index 0. With PS_ITER_SAMPLE only sample 0's invocation reaches the targets, so its sample and centroid barycentrics are taken to be sample 0's and the draw is shaded once. Both are inferred, not measured. ANCILLARY with POS_X_FLOAT or POS_Y_FLOAT throws, since reading the sample index makes the host shade per sample, which moves FragCoord from the pixel center to sample 0's location. By the same Vulkan rule, PERSP_CENTER and LINEAR_CENTER inputs on this path are interpolated at sample 0's location on the host, where the console uses the pixel center; one-sample depth images are created with `SAMPLE_LOCATIONS_COMPATIBLE_DEPTH` when the device supports it, as multisampled ones already were; this is how VK_AMD_mixed_attachment_samples defines the case, and it is not measured on PS5 hardware. Other mixed sample counts throw. Depth images remain in GENERAL between draws, and render passes cannot continue across pattern changes. Guest offsets retain the existing decoder's signed four-bit, sixteenth-pixel interpretation; PS5 coverage and interpolation equivalence have not been measured on hardware.
 - [DCC display buffers](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) are presented only when all keys of the console's DCC extent agree on uncompressed or a fast-clear code, padding keys included; other keys, and register-clear keys over a pending image, throw.

Subject: [PATCH 0640/1000] feat(agc): find the programs that store through the
 BDA table

A program writes guest memory through the BDA table only with a store or
an atomic through a PhysicalStorageBuffer pointer. SpirvStoresThroughAddresses
scans a module for such an instruction: it collects the PhysicalStorageBuffer
pointer types, every value of those types, and the stores, copies and
atomics whose pointer operand is one of them. A module it can't read to its
end counts as storing.

An address-based build now records whether its programs only read through
the table (ShaderResources::BdaReadOnly). Each module is scanned once; the
answer is kept by its content hash.

Subject: [PATCH 0641/1000] perf(agc): let a draw that only reads through the
 BDA table continue its render pass

recordDraw passed every address-based draw to the pass hazard tracker as
both an unknown reader and an unknown writer of guest memory. An unknown
writer conflicts with any earlier access in the pass, so no address-based
draw ever continued the previous draw's pass: each one ended the pass and
began a new one, which loads and stores the attachments again. At Resident
Evil Village's menu about half of all draws are address-based, and about
590 render passes begin for about 850 draws per frame.

A build whose programs only read through the BDA table now reports unknown
reads only. The tracker already orders unknown reads behind any recorded
range write in the pass and keeps later range writes behind them, so such
a draw continues a pass whose earlier draws wrote no guest ranges. Builds
with stores through the table, copied writes, or an address lease without
a table keep both flags. APS5_NO_ADDRESS_READ_PASSES=1 restores the old
behaviour.

Render targets reach guest memory only by explicit write-backs, so a read
through the table sees the same bytes whether or not the pass breaks.

Raghav314's #6947 makes the same change inside its GPU descriptor heap,
with the read-only fact from #6946's recompiler field; this one keeps it in
the driver, without a shader cache format change. The idea also comes from
fable-void's 5d57298425 (wip/new-gpu-path), which orders address-based
builds by their known access ranges; this takes the read-only half without
his run-time pre-pass bounds.

Subject: [PATCH 0643/1000] fix(shader): read low-half 16-bit multiply factors
 as 24-bit fields

On AMD's Windows driver 32.0.21045.5002 (RX 6700 XT), a product of two
values the driver knows fit in 16 bits, reduced to 16 bits and stored
with nothing else merged in, keeps all 32 bits of the product.
v_mul_lo_u16 and v_pk_mul_lo_u16 extracted 16-bit factors, so into a
register whose high half was zero they wrote 0xfffe0001 for
0xffff * 0xffff. A factor taken from the low half of its source is now
read as the low 24 bits of the register; the low 16 bits of the product
depend only on the low 16 bits of the factors.

 - [v_ldexp_f32 in denormal modes 1 and 2](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follows the `FLOAT_MODE` f32 denormal field: mode 1 keeps a subnormal input and flushes a result below 2^-126 to a zero of its sign in every f32 round mode, also one that rounds to 2^-126 at subnormal precision (`0x3fffffff` scaled by 2^-127); mode 2 flushes a subnormal input to a zero of its sign and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, as mode 3 does. Measured on RDNA2 (gfx1030, Radeon RX 6800, AMD Windows driver 32.0.21045.5002 through HIP) over 10,260 rows (54 inputs of both signs: zeros, subnormals, normals near 2^-126 and 1.0, the largest finite value, infinities and NaNs, each scaled by 190 exponents from -2^31 to 2^31-1) at IEEE=0 and IEEE=1 with each f32 denormal mode 0 to 3 and f32 round mode 0 to 3, DX10_CLAMP=1, f16 denormals kept, f16 round to nearest even and FP16_OVFL=0; with the `clamp` modifier the result is clamped as in the other modes. The PS5's gfx1013 is not measured.
 - [v_log_f32 and v_log_f16](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) keep the driver's log2 unless, for inputs within 1/8 of 1.0, it is more than 4 ULP from an eight-term series in x - 1, which then replaces it. `v_log_f16` goes through the same f32 lowering and is rounded to half. The series is evaluated for every `v_log` and chosen with `OpSelect` rather than a branch, so its seven fused multiply-adds and two multiplies are an unconditional cost. Measured on RDNA2 over all 3,145,728 f32 inputs within 1/8 of 1.0 (gfx1035, IEEE 0, f32 denormals flushed), the hardware is within 1 ULP of the correctly rounded log2 and the series within 2 ULP of it and within 3 ULP of the hardware (2 except at 0x3f752e47, 0x3f7baab0 and 0x3f7bc4fb), so a kept driver value is within 7 ULP of the hardware and a driver that returns the hardware's bits never triggers the gate; RADV (Mesa 26.2.4) returns the hardware's bits on the 9,280 such inputs measured on gfx1036; NVIDIA (615.71.09) was up to 23,947,836 ULP off at 1 - 2^-24 and is within 6 ULP inside the band after the change; outside it its own log2 stays up to 9 ULP off (measured up to 1.375). Over every f16 input, the change moves one `v_log_f16` result on NVIDIA (0x3bed, 1 ULP, onto the hardware's bits) and none on RADV.
 - [Ordered not-equal, less-than and greater-than compares](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) (shader recompiler) - `FPOrdNotEqual32` is emitted as `OpFUnordNotEqual`, and `FPOrdLessThan32` and `FPOrdGreaterThan32` as their ordered forms, each with both operands checked for NaN on their bits; the results are the same for every input. The AMD Windows driver 32.0.13058.8001 (Radeon 860M, RDNA 3.5) returns 1 for a NaN operand when any float form of not-equal feeds a ballot on a 32-wide subgroup (#825), and so does a less-than or greater-than against an infinity the driver sees as a constant (#3536), presumably rewritten into a not-equal by its compiler
+- [16-bit integer multiplies](../../../core/shader/recompiler/Translation/src/IntegerInstructions.cpp) (`v_mul_lo_u16`, `v_pk_mul_lo_u16`) (shader recompiler) - a factor taken from the low half of its source is read as the low 24 bits of the register, not the low 16; the low 16 bits of the product are the same for every input. The AMD Windows driver 32.0.21045.5002 (RX 6700 XT, RDNA 2) stores the full 32-bit product when two values it knows fit in 16 bits are multiplied, the product is reduced to 16 bits and nothing else is merged into the stored value: `v_mul_lo_u16` into a register whose high half is zero, also with factors masked to 16 bits by the program, and `v_pk_mul_lo_u16` whose high lanes are zero wrote 0xfffe0001 for 0xffff * 0xffff where the GPU writes 0x00000001. Reducing the product with `v_and_b32`, `v_bfe_u32` or a shift pair loses the same bits; factors read as 24-bit fields do not. Measured against the same instructions run through the [hardware oracle](../HW_ORACLE.md) on that GPU; other drivers are not checked
 - [f32 compares in denormal modes 1 and 2](../../../core/shader/recompiler/Translation/src/VectorInstructions.cpp) (`v_cmp_X_f32` and `v_cmpx_X_f32` with X = eq, ge, gt, le, lg, lt, neq, nge, ngt, nle, nlg, nlt) flush their f32 denormal inputs by bit 0 of the `FLOAT_MODE` f32 denormal field: mode 1 keeps them as mode 3 does, and mode 2 flushes them as mode 0 does. Measured on RDNA2 (gfx1030, Radeon RX 6800, AMD Windows driver 32.0.21045.5002 through HIP) over 484 operand pairs of zeros, denormals, minimum normals, ones, the largest finite value, infinities and quiet and signaling NaNs of both signs, in VOPC form, at IEEE=0 and IEEE=1 with each f32 denormal mode 0 to 3, f32 round to nearest even, DX10_CLAMP=1, f16 denormals kept, f16 round to nearest even and FP16_OVFL=0. The PS5's gfx1013 is not measured.
 - [DB_SHADER_CONTROL.PRIMITIVE_ORDERED_PIXEL_SHADER](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - the host pixel interlock spans the whole shader, not only up to `s_sendmsg` ORDERED_PS_DONE.
 - [POPS collision SGPRs](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - the collision wave ID and intrawave collision mask read 0, so a title skips its POPS wait and runs its per-collision loop once.

Subject: [PATCH 0644/1000] fix(libkernel): return EINVAL from read and write
 for a byte count above SSIZE_MAX

FreeBSD's read, write, pread and pwrite reject a byte count above
IOSIZE_MAX with EINVAL before they look up the descriptor. write threw
std::invalid_argument for a negative count, and the others passed the
count on to the host, which reports EFAULT on Linux.

Subject: [PATCH 0645/1000] fix(libkernel): return ENOTSUP from
 pthread_attr_setschedparam and setschedpolicy like libthr

FreeBSD's libthr rejects a null sched_param and, under SCHED_FIFO or
SCHED_RR, a priority outside sched_get_priority_min..max with ENOTSUP,
and a policy outside SCHED_FIFO..SCHED_RR with ENOTSUP. The wrappers
returned EINVAL for the null parameter and stored any priority or
policy.

Subject: [PATCH 0646/1000] fix(libkernel): return EINVAL/EFAULT from getrusage
 instead of throwing

FreeBSD's getrusage rejects an unknown `who` with EINVAL before it
copies anything out and returns EFAULT when the result can't be
written. The HLE threw std::invalid_argument for both, which ends the
title.

Subject: [PATCH 0647/1000] fix(shader): flush f16 compare inputs by the
 FLOAT_MODE f16 denormal field

v_cmp_X_f16 and v_cmpx_X_f16 compared denormal halves as their exact
values in every mode. On RDNA2 (gfx1031) f16 denormal modes 0 and 2
flush both inputs to a zero of the same sign first, so
v_cmp_eq_f16 0x0000, 0x0001 is true there. Both inputs now go through
flushF16InputValue; modes 1 and 3 and shaders without a known float
mode are translated as before.

The series is evaluated for every `v_log` and chosen with `OpSelect` rather than a branch, so its seven fused multiply-adds and two multiplies are an unconditional cost. Measured on RDNA2 over all 3,145,728 f32 inputs within 1/8 of 1.0 (gfx1035, IEEE 0, f32 denormals flushed), the hardware is within 1 ULP of the correctly rounded log2 and the series within 2 ULP of it and within 3 ULP of the hardware (2 except at 0x3f752e47, 0x3f7baab0 and 0x3f7bc4fb), so a kept driver value is within 7 ULP of the hardware and a driver that returns the hardware's bits never triggers the gate; RADV (Mesa 26.2.4) returns the hardware's bits on the 9,280 such inputs measured on gfx1036; NVIDIA (615.71.09) was up to 23,947,836 ULP off at 1 - 2^-24 and is within 6 ULP inside the band after the change; outside it its own log2 stays up to 9 ULP off (measured up to 1.375). Over every f16 input, the change moves one `v_log_f16` result on NVIDIA (0x3bed, 1 ULP, onto the hardware's bits) and none on RADV.
 - [Ordered not-equal, less-than and greater-than compares](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) (shader recompiler) - `FPOrdNotEqual32` is emitted as `OpFUnordNotEqual`, and `FPOrdLessThan32` and `FPOrdGreaterThan32` as their ordered forms, each with both operands checked for NaN on their bits; the results are the same for every input. The AMD Windows driver 32.0.13058.8001 (Radeon 860M, RDNA 3.5) returns 1 for a NaN operand when any float form of not-equal feeds a ballot on a 32-wide subgroup (#825), and so does a less-than or greater-than against an infinity the driver sees as a constant (#3536), presumably rewritten into a not-equal by its compiler

 - [DB_SHADER_CONTROL.PRIMITIVE_ORDERED_PIXEL_SHADER](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - the host pixel interlock spans the whole shader, not only up to `s_sendmsg` ORDERED_PS_DONE.
 - [POPS collision SGPRs](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - the collision wave ID and intrawave collision mask read 0, so a title skips its POPS wait and runs its per-collision loop once.
 - [Image loads](../../../core/shader/recompiler/Optimization/src/ResourceTracker.cpp) (shader recompiler) - an image_load reads a sampled binding, also of an image the shader stores to, so in a primitive-ordered pixel shader it misses an earlier overlapping primitive's image_store in the same draw.

Subject: [PATCH 0648/1000] fix(libkernel): read ITIMER_VIRTUAL and ITIMER_PROF
 as disarmed in getitimer

setitimer refuses to arm the CPU interval timers and already reads and
disarms them as zero, so they are never armed. getitimer threw for them
instead of reporting that state, as FreeBSD's kern_getitimer does for a
timer that is not set.

Subject: [PATCH 0649/1000] fix(libkernel): return EFAULT from fstat for a null
 stat buffer

FreeBSD's fstat looks the descriptor up before it copies the result
out, so a bad descriptor still fails with EBADF and an open one fails
with EFAULT when sb is null. fstat and sceKernelFstat threw
std::invalid_argument instead.

Subject: [PATCH 0650/1000] fix(shader): flush v_div_fixup_f16 src1 and src2 by
 the f16 denormal field

On RDNA2 (gfx1031) f16 denormal modes 0 and 2 flush the denominator and
numerator of v_div_fixup_f16 to a zero of the same sign and keep a
denormal quotient and result, as v_div_fixup_f32 does with the f32
field. The translation used them unflushed in every mode, so 0x0001 / 0
gave +infinity instead of the default NaN.

 - [Signaling NaN inputs](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) of the f32 and f16 unary instructions (`v_sqrt/rcp/rsq/log/exp/sin/cos/fract/floor/ceil/trunc/rndne/rcp_iflag/frexp_mant`), `v_ldexp_f32/f16`, `v_frexp_mant_f16`, `v_div_fixup_f32/f16` and `v_mullit_f32` are returned quieted only with IEEE=1 and unchanged with IEEE=0, measured on RDNA2 (gfx1035) in both modes, and so are those of the f64 forms (`v_sqrt/rcp/rsq/fract/floor/ceil/trunc/rndne/frexp_mant/ldexp/div_fixup_f64`) and `v_cvt_f64_f32`, measured on RDNA2 (gfx1036) in both modes; shaders without a known float mode follow IEEE=0. `v_pack_b32_f16` quiets each signaling NaN half by the same rule, measured on RDNA2 (gfx1036) in both modes. A signaling NaN result of `v_cubesc/cubetc/cubema_f32` is quieted by the same rule and keeps the sign the instruction gives it, measured on RDNA2 (gfx1036) in both modes. `v_add/sub/subrev/mul/fma/fmac/fmamk/fmaak/mul_legacy_f32` and `v_fma_mix_f32` with f32 sources choose their NaN result on the bits, measured over 1000 operand triples in both modes: the first NaN source in operand order after its modifiers (the subtrahend negated, as the hardware adds its negation), quieted only with IEEE=1, or the default NaN 0xffc00000 for an invalid operation; in the fma forms an invalid product (inf * 0) gives the default NaN even when src2 is a NaN, and in the legacy forms a zero factor makes the product 0 even when the other factor is a NaN (a NaN src2 still wins). `v_mad_legacy_f32` and `v_mac_legacy_f32` follow the same rule with their separately rounded product, as measured on gfx1010 (#1281, #1290): a NaN source quieted only with IEEE=1, inf - inf giving 0xffc00000, the zero rule hiding a NaN factor and a NaN src2 winning. The f16 and f64 arithmetic, `v_fma_mix_f32` with f16 sources and the separately rounded mad/mac forms (not measurable on RDNA2) follow the same rule on hardware but their NaN bits are left to the driver. `v_cvt_f16_f32`, `v_cvt_f32_f64`, `v_dot2_f32_f16`, `v_fma_mixlo_f16` and `v_fma_mixhi_f16` always quiet and `v_div_scale_f32` never does: the f32 signaling NaN 0x7f812345 as src0 or src2 gives 0x7e09 from mixlo and mixhi at IEEE=0 and IEEE=1 on RDNA2 (gfx1036), where `v_fma_mix_f32` gives 0x7f812345 at IEEE=0 and 0x7fc12345 at IEEE=1. The payload of an f16 NaN source of mixlo and mixhi is left to the driver's f16 to f32 conversion, which NVIDIA replaces.
 - [Scalar f16 add, sub, subrev and mul denormals](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follow the `FLOAT_MODE` f16 denormal field at nearest-even: bit 0 preserves inputs and bit 1 preserves the result; otherwise a denormal is flushed to its signed zero. Measured on RDNA2 (gfx1036) with IEEE=0/1 and FP16_OVFL=0/1, over 32 operand pairs in all four denormal modes, including signed zeros, denormals, minimum normals, infinities and NaNs. Multiply detects tininess after rounding to 11 significant bits with an unbounded exponent, before gradual half packing: `0x3bff * 0x0400` flushes, while `0x3c01 * 0x03ff` rounds to `0x0400` and is kept. Directed rounding and ternary arithmetic keep their previous denormal lowering. Shaders without a known float mode keep the previous lowering. Scalar `v_sub_f16`/`v_subrev_f16` share `float16Binary` with add/mul and were measured on gfx1036 over the same operand set as add (1156 non-NaN-input rows per mode); NaN result bits still depend on the driver as recorded above.
 - [f16 unary, frexp and conversion denormals](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follow the `FLOAT_MODE` f16 denormal field: `v_ceil_f16`, `v_floor_f16`, `v_fract_f16`, `v_rcp_f16`, `v_rsq_f16`, `v_sqrt_f16`, `v_log_f16`, `v_exp_f16`, `v_sin_f16`, `v_frexp_mant_f16`, `v_frexp_exp_i16_f16`, `v_cvt_norm_i16_f16`, `v_cvt_norm_u16_f16` and `v_cvt_f32_f16` flush a denormal half input to its signed zero when bit 0 is clear (0 and 2), and the f16-result ones flush a denormal half result to its signed zero when bit 1 is clear (0 and 1), after the host rounds it to half. Measured on RDNA2 (gfx1036) at IEEE=0 and IEEE=1 with denorm16 0..3 over every non-NaN f16 input (63,490 rows per mode and instruction): the only mismatches are the 1-ULP driver differences of `v_exp_f16` (2 inputs) and `v_sin_f16` (14), which are the same with denormals kept. NaN inputs are not compared. `v_ldexp_f16` shares the input rule. `v_cvt_pknorm_i16_f16` and `v_cvt_pknorm_u16_f16` flush both half inputs by the same bit, measured on RDNA2 (gfx1030) over every f16 input (each half also negated in the other source) at IEEE=0 and IEEE=1 with denorm16 0..3 and at f16 rounding 1..3: every row matches. Shaders without a known float mode keep the previous lowering.
+- [v_div_fixup_f16](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) flushes its src1 and src2 to a zero of the same sign when bit 0 of the `FLOAT_MODE` f16 denormal field is clear (0 and 2) and keeps a denormal src0 and result in every mode, as `v_div_fixup_f32` does with the f32 field. Measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) over 6859 triples of 19 halves (zeros, denormals, minimum normals, ±0.5, ±1, the largest finite value, infinities and quiet and signaling NaNs) at IEEE=0 and IEEE=1 with denorm16 0..3 and FP16_OVFL 0 and 1, also with neg and abs source modifiers and with op_sel high halves. Shaders without a known float mode keep the previous lowering. The PS5's gfx1013 is not measured.
 - [Packed f16 NaN results](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (`v_pk_add/mul/fma/min/max_f16`) follow the hardware measured on RDNA2 (gfx1035) at IEEE=0 and IEEE=1 with f16 round-to-nearest-even and f16 denormals kept: with IEEE=1 a signaling NaN input is quieted and min/max return the other operand only for a quiet NaN; with IEEE=0 NaN inputs pass through unquieted and min/max ignore signaling. In `v_pk_fma_f16` an invalid product (inf * 0) gives the default NaN even when src2 is a NaN. A shader without a known float mode is translated as IEEE=0, the mode titles use; a mode with another f16 rounding or that flushes f16 denormals throws.
 - [f32 denormals](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follow the shader's `FLOAT_MODE` f32 denormal field (bits 5:4) when it flushes them (0, and shaders without a known float mode, as in the 0xc0 most titles use), measured on RDNA2 (gfx1035) over 1444 rows per instruction at IEEE=0 and IEEE=1. `v_add/sub/subrev/mul/mul_legacy/mullit/fma/fmac/fmamk/fmaak/min/max/min3/max3/med3/fract/floor/ceil/frexp_mant/sin/cos_f32` flush their f32 inputs and their result to a zero of the same sign (`v_mullit_f32` measured on RDNA2 (gfx1036) over 6907 rows per mode at IEEE=0 and IEEE=1, so a positive denormal src2 counts as zero); the f32 compares, `v_cvt_i32/u32/rpi_i32/flr_i32_f32`, `v_frexp_exp_i32_f32`, `v_cvt_f64_f32`, `v_cvt_f16_f32`, `v_cvt_pkrtz_f16_f32`, `v_cvt_pknorm_i16/u16_f32` and `v_cvt_pk_u8_f32` flush their f32 inputs. `v_div_scale_f32` flushes all three inputs to signed zeros, measured on RDNA2 (gfx1036) over 2744 operand triples per mode at IEEE=0 and IEEE=1 with f32 denormals flushed and kept; its scale-down behaviour and host denormal preservation remain incomplete. `v_div_fixup_f32` flushes its src1 and src2 and keeps a denormal src0 and result, measured on RDNA2 (gfx1036) over 6859 rows per mode at IEEE=0 and IEEE=1. Tininess is detected after rounding, measured on RDNA2 (gfx1036) for `v_mul_f32` and `v_mullit_f32` at IEEE=0 and IEEE=1: a product is flushed when its value rounded to 24 bits with an unbounded exponent is below 2^-126, so `0x3f7ffffe * 0x00800001` (2^-126 * (1 - 2^-46)) gives `0x00800000` and `0x3f7fffff * 0x00800000` (2^-126 * (1 - 2^-24)) gives zero. The check rounds in the f32 round mode of `FLOAT_MODE` (bits 1:0), measured in all four modes, while the products themselves are still rounded to nearest even. This applies to `v_mul_f32`, `v_mul_legacy_f32`, `v_mullit_f32`, and to `v_fma_f32`, `v_fmac_f32`, `v_fmamk_f32`, `v_fmaak_f32` and `v_fma_mix_f32` when the addend is zero; with a nonzero addend the fused result is kept, so an exact result just below 2^-126 that rounds to it is not flushed. In the three directed modes the check is computed exactly from the significands. To nearest even (0, the mode of shaders without a known float mode) one factor is multiplied by 2^64, which is exact below 2^64, and the product with the other factor is compared with 2^-62. That multiply is a plain `OpFMul` like the product, and no f32 rounding mode is requested in the SPIR-V, so the check relies on the driver rounding f32 to nearest even by default, as the products do, and a product that rounds up to 2^-126 is the emitted product. `v_fma_mix_f32` follows this rule with mixed f16/f32 sources too, measured on RDNA2 (gfx1036) with f16 in either multiplicand slot, low and high half selection, and an f32 or f16 zero addend: f32 `0x00801002` times f16 `0x3bff` gives `0x00800000` to nearest at IEEE=0 and IEEE=1, while the neighbours `0x00801001` and `0x00801003` give zero and `0x00800001`. The tiny-product boundary was also measured for both signs in all four f32 round modes at IEEE=0; f16 inputs retain their previous conversion and denormal handling. `v_fma_mixlo_f16` and `v_fma_mixhi_f16` flush their f32 sources too and keep a product below 2^-126, measured on RDNA2 (gfx1036). `v_mad_legacy_f32` and `v_mac_legacy_f32` flush their inputs, their product and their result in every mode, see its entry; their product is still checked for tininess on its exact value, so one below 2^-126 gives zero even when it rounds to 2^-126, as the console's separately rounded encoding is not measured at this boundary. Denormal modes 1 and 2 throw for the other instructions. Not covered, and not measurable on RDNA2 (no such opcodes) or not measured: `v_mac_f32`, `v_mad_f32`, `v_madak_f32` and `v_madmk_f32` (rounded separately), `v_dot2_f32_f16` and `v_div_fmas_f32` (on hardware `v_div_fmas_f32` flushes only its result), f32 interpolation and `ds_add_f32` keep the previous lowering; `ds_min/max/cmpst_f32` flush both operands by the field, see the LDS float atomics entry. With f32 denormals kept (3) the results depend on the driver's default denormal behaviour, as no `DenormPreserve` execution mode is requested; `v_ldexp_f32` and the f32 compares are the exceptions. `v_cmp_X_f32` and `v_cmpx_X_f32` compare the operands as sign-magnitude integers with the NaN cases handled apart, so a denormal is not read as zero, measured on RDNA2 (gfx1036) over 256 operand pairs per opcode at IEEE=0 and IEEE=1 with f32 denormals kept and flushed. `v_ldexp_f32` preserves subnormal inputs and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, measured on RDNA2 (gfx1036) over 2163 rows in each of the four round modes at IEEE=0 and IEEE=1. An overflow rounds like any other result (infinity, or the largest finite value when the mode rounds that sign toward zero). With f32 denormals flushed it flushes a subnormal input and result, measured over the same rows in each round mode at IEEE=0 only. A device whose driver splits `Fma` into a multiply and an add flushes a product below 2^-126 before adding a non-zero addend in `v_fma_f32` and `v_fmac_f32`: `0x1fffffff * 0x1fffffff + 0x00800000` gives `0x00800000` instead of the fused `0x00ffffff` on RADV RENOIR (Mesa 26.2.4), whose compiled shader has `v_mad_f32` and no `v_fma_f32`. [F32DenormalFlush](../../../core/libs/prx/libSceAgcDriver/tests/execution/F32DenormalFlush.cpp) accepts that sum on such a device.
 - [v_rcp, v_rsq, v_sqrt, v_log, v_exp, v_sin and v_cos](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (f32 and f16) use the driver's approximation for finite results, not the console's: the low bits can differ. Only NaN, invalid, zero and infinite results and the exact sin/cos zeros are chosen on the bits. Measured on RDNA2 (gfx1036) over every f16 input and 32,832 f32 inputs: RADV returns the hardware's bits for every input of rcp, rsq, sqrt and log and all but one of exp (f16 0x11c5, 1 ULP); NVIDIA (615.71.09) stays within 2 ULP except `v_log_f32` near 1.0 (next entry). [v_sin and v_cos](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) take the driver's sine or cosine of the radians of the exact cycle, except within 2^-12 of a turn from a zero of the function, where the result is the linear term of the exact distance to the zero: the hardware's constant 6.2831826 (0x40c90fd5) at the integers, which the hardware applies exactly to inputs below 2^-12 of a turn, and the f32 2π at the half and quarter turns, where the hardware is within 7 ULP of it. Outside those bands, a driver result more than 4 ULP from a Taylor series in turns of the exact cycle is replaced by the series, which is within 2 ULP of the true sine and cosine; the hardware is up to 9 ULP from them (gfx1035, 243,092 f32 inputs), so results stay within 13 ULP of the hardware on any driver. RADV returns the hardware's bits for every f16 input and for 32,422 sine and 32,486 cosine results of the 32,832 f32 inputs; the rest are 1 ULP off, except up to 14 ULP on either side of non-zero integers and up to 15 ULP beyond ±256 cycles, where the hardware's own reduction differs from the exact fraction, and up to 6 ULP inside the half- and quarter-turn bands. NVIDIA's own sine is within 1 ULP on 93% of the f32 inputs and up to 1,166 ULP off just outside the bands, its cosine within 163 ULP; the series replaces those results. A denormal f32 input with f32 denormals kept gives the hardware the input times 6.2831826; both hosts flush it.

Subject: [PATCH 0651/1000] fix(libkernel): return EINVAL from the
 scePthreadAttr stack and guard size calls

scePthreadAttrGetstack, Getstackaddr, Getguardsize, Setguardsize,
Setstack and Setstackaddr threw for a null attribute, a null pointer
argument or a stack below the 16 KiB minimum. FreeBSD's libthr returns
EINVAL for those, as the pthread_attr_* wrappers here and the other
scePthreadAttr calls already do.

Subject: [PATCH 0652/1000] fix(shader): flush v_cvt_pkrtz_f16_f32 and
 v_pack_b32_f16 f16 denormals

Both ignored the FLOAT_MODE f16 denormal field. On RDNA2 (gfx1031)
v_cvt_pkrtz_f16_f32 flushes each denormal half result to its signed zero
when bit 7 of FLOAT_MODE is clear, and v_pack_b32_f16 flushes each
denormal half input when bit 6 is clear. Modes that keep them and
shaders without a known float mode are translated as before.

 - The [clamp modifier](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follows `DX10_CLAMP`, measured on RDNA2 (gfx1035) for f32, f16, packed f16 and f64 results at IEEE=0 and IEEE=1: with `DX10_CLAMP`=1 (and in shaders without a known float mode) a NaN result clamps to +0, including the quieted NaN that `v_pk_min_f16` and `v_pk_max_f16` return for a signaling NaN operand with IEEE=1 (measured on RDNA2 gfx1036 at both `IEEE_MODE` and both `DX10_CLAMP` settings); with `DX10_CLAMP`=0 a NaN result is written unchanged and every other value clamps to [0, 1] as before. f64 results follow the same rule on hardware, but a clamped f64 result with `DX10_CLAMP`=0 throws until it has an execution test. With `DX10_CLAMP`=0 the NaN's bits are those the translation already produces for the instruction without clamp, so where those are left to the driver (f32 and scalar f16 arithmetic) the payload is the driver's, not the hardware's input propagation. `v_dot2_f32_f16` and the integer clamps are unchanged.
 - [FP16_OVFL](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follows the shader's float mode as measured on RDNA2 (gfx1036) at IEEE=0 and IEEE=1 with f16 denormals kept and flushed: with `FP16_OVFL`=1 an f16 result that rounds to ±infinity is written as ±0x7bff unless a source operand is infinite, so `v_rcp_f16`, `v_rsq_f16` and `v_log_f16` of ±0 and `v_exp_f16` of 16 or more are clamped while an infinite input passes through, and `v_div_fixup_f16` keeps the infinity it writes for a zero denominator or an infinite numerator and clamps any other infinite quotient, a NaN one included. `v_cvt_pkrtz_f16_f32` rounds toward zero and never overflows. The sources are checked as the f32 values the translation computes with; the rule is applied to `v_fma_mix*_f16` with f32 sources and to `v_interp_p2_f16` without a measurement of infinite f32 sources or parameters. Round modes other than nearest even are not modelled, so the overflow threshold is the nearest-even one (65520).
 - [Directed f16 rounding](../../../core/shader/recompiler/Translation/src/TranslationContext/SubwordPacking.cpp) for `v_cvt_f16_f32`, `v_cvt_f16_i16`, `v_cvt_f16_u16` and `v_ldexp_f16` follows `FLOAT_MODE` bits 3:2 in every f16 denormal mode, measured on RDNA2 (gfx1036 with f16 denormals preserved, gfx1030 in all sixteen combinations of f16 rounding and denormal mode). When bit 7 flushes f16 results, `v_cvt_f16_f32`, `v_cvt_f16_i16` and `v_cvt_f16_u16` write a zero of the result's sign for a value that, rounded in that mode with an unbounded exponent, is below 2^-14, so a value just below 2^-14 that rounds up to it stays 0x0400; `v_ldexp_f16` keeps its rule above. The `clamp` modifier is applied before the rounding. On gfx1030 every row matches: 8,996 f32 inputs around the half denormal, normal and overflow boundaries with and without `clamp`, every 16-bit integer, and 2,470 `v_ldexp_f16` operands.
+- [v_cvt_pkrtz_f16_f32 and v_pack_b32_f16 denormals](../../../core/shader/recompiler/Translation/src/ConvertInstructions.cpp) follow the `FLOAT_MODE` f16 denormal field: `v_cvt_pkrtz_f16_f32` flushes each denormal half result to its signed zero when bit 1 is clear (0 and 1), and `v_pack_b32_f16` flushes each denormal half input to its signed zero when bit 0 is clear (0 and 2). Measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) at IEEE=0 and IEEE=1 with denorm16 0..3 and f32 denormals kept, over 256 pairs of 16 f32 values around the f16 denormal range for `v_cvt_pkrtz_f16_f32` and 256 pairs of 16 halves (zeros, denormals, minimum normals, ±1, the largest finite value, infinities and quiet and signaling NaNs) for `v_pack_b32_f16`. Shaders without a known float mode keep the previous lowering. The PS5's gfx1013 is not measured.
 - [Comparison sampling of a color texture](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) (`image_sample_c`/`image_sample_c_lz` on a texture that is not R32 float or R16 unorm) is emulated in the shader, since Vulkan compares only depth formats: the red channel is fetched, compared and, for bilinear filtering, blended (compare, then filter). Only 2D, 2D array and cube views, float/unorm/snorm formats, wrap, clamp-to-edge and clamp-to-border addressing (border red 0 for the black borders, 1 for opaque white) and point or bilinear filtering at one level are implemented, with texel offsets added to the texel indices; LOD biases and clamps are accepted, as they cannot select another level of a single-level sample. Half-border addressing, the border color table, gradients, gathers, other dimensions, anisotropy (except on the 8-bit formats below) and mip filtering throw. Under bilinear filtering, taps past a clamp-to-border edge compare the border value and blend with the texel taps, so results near the edge depend on the filter weights. AMD documentation does not say how a color format's reference is handled: it is clamped to [0, 1] for unorm and [-1, 1] for snorm, as Vulkan does for unorm depth, and not clamped for float. 8-bit sRGB and UNORM (`Format8Srgb`, `Format8_8Srgb`, `Format8_8_8_8Srgb`, `Format8UNorm`, `Format8_8UNorm`, `Format8_8_8_8UNorm`) return 0 for every compare function, measured with `image_sample_c_lz` on gfx1035 over references -0.5..1.5 and texel codes 0..255. A bilinear cube of those 8-bit formats without `DISABLE_CUBE_WRAP`, and an anisotropic S# on them, return 0 for the same reason; float, snorm and the other unorm bilinear cubes without that bit still throw. Bilinear weights are full float, not the hardware's fixed-point subtexel weights
 - [Negative color-texture comparison wrap indices](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) (libSceAgcDriver) use explicit `OpSRem` normalization to implement modulo; the negative-offset point-wrap regression fails with direct `OpSMod` and passes with normalization on Mesa 22.3.6 llvmpipe (LLVM 15.0.6), but negative-index wrap has not been measured on PS5 hardware.
 - [Converted unorm images](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) (10_11_11_UNORM, read and written through an R32_UINT view): samples, gathers, LOD queries, 16-bit data and a DST_SEL of the missing W channel throw.

Subject: [PATCH 0653/1000] fix(libkernel): return 0 from sceKernelMprotect and
 sceKernelMtypeprotect for a zero length

mprotect already returns 0 for a zero length. The sceKernel entry
points passed it to DoMprotect, which throws for an empty range.

Subject: [PATCH 0654/1000] fix(libkernel): return EINVAL from
 scePthreadCondattrSetclock and Destroy for a null attribute

Both threw std::invalid_argument for a null or uninitialized attribute.
FreeBSD's libthr returns EINVAL for one, as the other scePthread
attribute calls here already do. The clock id is still stored as
given.

Subject: [PATCH 0655/1000] fix(shader): flush v_fma_f16 family denormals by
 the f16 denormal field

v_fma_f16, v_fmac_f16, v_fmamk_f16 and v_fmaak_f16 ignored the
FLOAT_MODE f16 denormal field. On RDNA2 (gfx1031) at f16 round to
nearest even, bit 6 clear flushes every denormal input to a zero of its
sign, and bit 7 clear flushes the result when the exact product-sum
rounded to 11 significant bits with an unbounded exponent is below
2^-14, the rule v_mul_f16 already follows. The f16 FMA path now flushes
its inputs and its round-to-odd result in those modes; the magnitude
test is shared with float16Binary as flushTinyF16Value.

 - [v_mad_legacy_f32 and v_mac_legacy_f32](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (VOP3 0x140, VOP2 0x06) round the product to f32 before the add, give a +0 product for a zero factor, and flush their f32 denormal sources, their product and their result to a zero of the same sign in every f32 denormal mode, an exception to the `FLOAT_MODE` model in [f32DenormalFlushFor](../../../core/shader/recompiler/Translation/src/VectorInstructions.cpp). Measured on gfx1010 (RX 5700 XT) with `tools/hw-oracle/template.s`, assembled by the AMD Windows driver's `amd_comgr_2.dll` and launched through its `amdhip64_6.dll` instead of `oracle.c` and ROCr, over the 32 rows of the five `FmaLegacy.cpp` and the four `MacLegacy.cpp` encodings: identical in wave32 and wave64 at IEEE 0 and 1 with f32 denormal modes 0 to 3, except that the two signaling NaN rows are quieted only with IEEE=1 (#1281, #1290). A sum of two zeros takes its sign on the bits (+0 unless both are -0), as lavapipe returned -0 for +0 + -0. The PS5's gfx1013 is not measured; LLVM decodes the encoding as `v_mad_legacy_f32` there, as on gfx1010. RDNA2 differs: on gfx1031 (RX 6700 XT, measured by pandather in #1281) the encoding is `v_fma_legacy_f32` and fused, with the same zero rule and denormal-source flush, so an RDNA2 measurement is not evidence for the console.
 - [v_fma_mixlo_f16 and v_fma_mixhi_f16](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) round the exact product-sum once to f16 with the f64 arithmetic of v_interp_p2_f16, so they need the Float64 capability. On RDNA2 (gfx1036) they follow the `FLOAT_MODE` f16 round and denormal fields, not the f32 round field: -1.5 * 2^-24 + 2^-126 from f32 sources (0xbfc00000, 0x33800000, 0x00800000) gives 0x8001 with f16 denormals kept and round to nearest even, 0x8000 with f16 denormals flushed and 0x8002 with f16 round toward -infinity. With f16 denormals kept, every f16 rounding mode is translated: the exact product-sum is rounded once in the mode's direction. All four modes match RDNA2 (gfx1036) on the 2,233 rows of the #2631 sweep, including `FLOAT_MODE` 0xcc (toward zero, used by ps5-opengl) and the exact cancellations toward -infinity; the PS5's gfx1013 is not measured. A result beyond 65504 becomes infinity or 65504 as IEEE 754 gives for the mode. Flushed f16 denormals still throw, and packed f16 still throws in every mode but round to nearest even with f16 denormals kept. `FP16_OVFL` set is not measured.

A signaling NaN result of `v_cubesc/cubetc/cubema_f32` is quieted by the same rule and keeps the sign the instruction gives it, measured on RDNA2 (gfx1036) in both modes. `v_add/sub/subrev/mul/fma/fmac/fmamk/fmaak/mul_legacy_f32` and `v_fma_mix_f32` with f32 sources choose their NaN result on the bits, measured over 1000 operand triples in both modes: the first NaN source in operand order after its modifiers (the subtrahend negated, as the hardware adds its negation), quieted only with IEEE=1, or the default NaN 0xffc00000 for an invalid operation; in the fma forms an invalid product (inf * 0) gives the default NaN even when src2 is a NaN, and in the legacy forms a zero factor makes the product 0 even when the other factor is a NaN (a NaN src2 still wins). `v_mad_legacy_f32` and `v_mac_legacy_f32` follow the same rule with their separately rounded product, as measured on gfx1010 (#1281, #1290): a NaN source quieted only with IEEE=1, inf - inf giving 0xffc00000, the zero rule hiding a NaN factor and a NaN src2 winning. The f16 and f64 arithmetic, `v_fma_mix_f32` with f16 sources and the separately rounded mad/mac forms (not measurable on RDNA2) follow the same rule on hardware but their NaN bits are left to the driver. `v_cvt_f16_f32`, `v_cvt_f32_f64`, `v_dot2_f32_f16`, `v_fma_mixlo_f16` and `v_fma_mixhi_f16` always quiet and `v_div_scale_f32` never does: the f32 signaling NaN 0x7f812345 as src0 or src2 gives 0x7e09 from mixlo and mixhi at IEEE=0 and IEEE=1 on RDNA2 (gfx1036), where `v_fma_mix_f32` gives 0x7f812345 at IEEE=0 and 0x7fc12345 at IEEE=1. The payload of an f16 NaN source of mixlo and mixhi is left to the driver's f16 to f32 conversion, which NVIDIA replaces.

In `v_pk_fma_f16` an invalid product (inf * 0) gives the default NaN even when src2 is a NaN. A shader without a known float mode is translated as IEEE=0, the mode titles use; a mode with another f16 rounding or that flushes f16 denormals throws.
 - [f32 denormals](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follow the shader's `FLOAT_MODE` f32 denormal field (bits 5:4) when it flushes them (0, and shaders without a known float mode, as in the 0xc0 most titles use), measured on RDNA2 (gfx1035) over 1444 rows per instruction at IEEE=0 and IEEE=1. `v_add/sub/subrev/mul/mul_legacy/mullit/fma/fmac/fmamk/fmaak/min/max/min3/max3/med3/fract/floor/ceil/frexp_mant/sin/cos_f32` flush their f32 inputs and their result to a zero of the same sign (`v_mullit_f32` measured on RDNA2 (gfx1036) over 6907 rows per mode at IEEE=0 and IEEE=1, so a positive denormal src2 counts as zero); the f32 compares, `v_cvt_i32/u32/rpi_i32/flr_i32_f32`, `v_frexp_exp_i32_f32`, `v_cvt_f64_f32`, `v_cvt_f16_f32`, `v_cvt_pkrtz_f16_f32`, `v_cvt_pknorm_i16/u16_f32` and `v_cvt_pk_u8_f32` flush their f32 inputs. `v_div_scale_f32` flushes all three inputs to signed zeros, measured on RDNA2 (gfx1036) over 2744 operand triples per mode at IEEE=0 and IEEE=1 with f32 denormals flushed and kept; its scale-down behaviour and host denormal preservation remain incomplete. `v_div_fixup_f32` flushes its src1 and src2 and keeps a denormal src0 and result, measured on RDNA2 (gfx1036) over 6859 rows per mode at IEEE=0 and IEEE=1. Tininess is detected after rounding, measured on RDNA2 (gfx1036) for `v_mul_f32` and `v_mullit_f32` at IEEE=0 and IEEE=1: a product is flushed when its value rounded to 24 bits with an unbounded exponent is below 2^-126, so `0x3f7ffffe * 0x00800001` (2^-126 * (1 - 2^-46)) gives `0x00800000` and `0x3f7fffff * 0x00800000` (2^-126 * (1 - 2^-24)) gives zero. The check rounds in the f32 round mode of `FLOAT_MODE` (bits 1:0), measured in all four modes, while the products themselves are still rounded to nearest even. This applies to `v_mul_f32`, `v_mul_legacy_f32`, `v_mullit_f32`, and to `v_fma_f32`, `v_fmac_f32`, `v_fmamk_f32`, `v_fmaak_f32` and `v_fma_mix_f32` when the addend is zero; with a nonzero addend the fused result is kept, so an exact result just below 2^-126 that rounds to it is not flushed. In the three directed modes the check is computed exactly from the significands. To nearest even (0, the mode of shaders without a known float mode) one factor is multiplied by 2^64, which is exact below 2^64, and the product with the other factor is compared with 2^-62. That multiply is a plain `OpFMul` like the product, and no f32 rounding mode is requested in the SPIR-V, so the check relies on the driver rounding f32 to nearest even by default, as the products do, and a product that rounds up to 2^-126 is the emitted product. `v_fma_mix_f32` follows this rule with mixed f16/f32 sources too, measured on RDNA2 (gfx1036) with f16 in either multiplicand slot, low and high half selection, and an f32 or f16 zero addend: f32 `0x00801002` times f16 `0x3bff` gives `0x00800000` to nearest at IEEE=0 and IEEE=1, while the neighbours `0x00801001` and `0x00801003` give zero and `0x00800001`. The tiny-product boundary was also measured for both signs in all four f32 round modes at IEEE=0; f16 inputs retain their previous conversion and denormal handling. `v_fma_mixlo_f16` and `v_fma_mixhi_f16` flush their f32 sources too and keep a product below 2^-126, measured on RDNA2 (gfx1036). `v_mad_legacy_f32` and `v_mac_legacy_f32` flush their inputs, their product and their result in every mode, see its entry; their product is still checked for tininess on its exact value, so one below 2^-126 gives zero even when it rounds to 2^-126, as the console's separately rounded encoding is not measured at this boundary. Denormal modes 1 and 2 throw for the other instructions. Not covered, and not measurable on RDNA2 (no such opcodes) or not measured: `v_mac_f32`, `v_mad_f32`, `v_madak_f32` and `v_madmk_f32` (rounded separately), `v_dot2_f32_f16` and `v_div_fmas_f32` (on hardware `v_div_fmas_f32` flushes only its result), f32 interpolation and `ds_add_f32` keep the previous lowering; `ds_min/max/cmpst_f32` flush both operands by the field, see the LDS float atomics entry. With f32 denormals kept (3) the results depend on the driver's default denormal behaviour, as no `DenormPreserve` execution mode is requested; `v_ldexp_f32` and the f32 compares are the exceptions. `v_cmp_X_f32` and `v_cmpx_X_f32` compare the operands as sign-magnitude integers with the NaN cases handled apart, so a denormal is not read as zero, measured on RDNA2 (gfx1036) over 256 operand pairs per opcode at IEEE=0 and IEEE=1 with f32 denormals kept and flushed. `v_ldexp_f32` preserves subnormal inputs and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, measured on RDNA2 (gfx1036) over 2163 rows in each of the four round modes at IEEE=0 and IEEE=1. An overflow rounds like any other result (infinity, or the largest finite value when the mode rounds that sign toward zero). With f32 denormals flushed it flushes a subnormal input and result, measured over the same rows in each round mode at IEEE=0 only. A device whose driver splits `Fma` into a multiply and an add flushes a product below 2^-126 before adding a non-zero addend in `v_fma_f32` and `v_fmac_f32`: `0x1fffffff * 0x1fffffff + 0x00800000` gives `0x00800000` instead of the fused `0x00ffffff` on RADV RENOIR (Mesa 26.2.4), whose compiled shader has `v_mad_f32` and no `v_fma_f32`. [F32DenormalFlush](../../../core/libs/prx/libSceAgcDriver/tests/execution/F32DenormalFlush.cpp) accepts that sum on such a device.

Subject: [PATCH 0656/1000] feat(agc): store to images selected through image
 tables

An IMAGE_STORE whose T# comes from a runtime-indexed image table used to
poison the whole table as an unsupported operation. Written, non-atomic
table images now get storage modes, a STORAGE_IMAGE table binding (260,
the sampled image table moves to 261 and keeps the variable count), and
storage views of tracked storage textures at the same element indices.
Every bound entry is marked written, so each dispatch writes back all of
the table's storage images. Atomic, packed, BY2/BY4 and dynamic-mip table
stores still fault. Tables with written entries are not reused.

Subject: [PATCH 0657/1000] test(agc): expect image_store through a table to
 bind written storage elements

The shader memory registration test pinned the old refusal. It now checks
that the store's table is supported, does not fault, and binds every
element as written on the storage table binding, and that a store-only
table binds no sampled elements. The driver no longer requires a written
flag per table element, so bindings that carry none read as unwritten.

Subject: [PATCH 0658/1000] fix(agc): size the pool for the storage table and
 check table store elements like direct ones

The non-split descriptor set's pool now counts the storage table binding's
descriptors, as the split path already did. A table storage element whose
minimum LOD clamps above the level it addresses is rejected per element, as
the direct path refuses it, and the element is looked up as written so a depth
surface under it is retired. The registration test checks again that
image_store_mip, image_store_pck and image_atomic_add through a table stay
unsupported operations that fault on use.

 - [VertexBufferReadSize](../../../core/libs/prx/libSceAgcDriver/Graphics/include/VertexInput.hpp) and the [vertex staging copy](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver) - a vertex fetch whose index is at or past the descriptor's `num_records` no longer throws for `OOB_SELECT` 0 and 1. The copy still spans the whole fetch, but the bytes from `num_records * stride` onward read as zeros, so the out-of-range vertex is `(0, 0, 0, 0)`. Measured with `buffer_load_format_xyzw` (`idxen`) through the [hardware oracle](../HW_ORACLE.md) on RDNA2 gfx1036 for PPSA01325's word 3 `0x0004dfac` (`OOB_SELECT` 0) in #2241: indices 3, 4 and 5 over 3 records each return `00000000 00000000 00000000 00000000`, W included, unlike Vulkan `robustBufferAccess`, which returns `(0, 0, 0, 1)`. The zeros come from the record check, not from memory: stored values placed past the records are ignored, and a `num_records` 6 control returns them. `RESOURCE_LEVEL` 1, `OOB_SELECT` 1 and FORMAT 74 `32_32_32_FLOAT` give the same zeros, in wave32 and wave64; gfx1013 (the console) is not measured. `OOB_SELECT` 2 returns the stored values past the records and `OOB_SELECT` 3 compares `num_records` against the byte offset, both measured on the same setup in #2241; the two keep throwing past `num_records` here, since each needs its own rule. Zero-stride descriptors (`stride` 0) keep their separate byte-count check and are not covered here. Each out-of-range fetch is copied alone and outside the draw-snapshot cache, which is neither read nor written for it: a reused snapshot would carry another draw's bytes into the zero region, and a stored zero-padded copy would hand zeros to a later in-range draw at the same address. The valid prefix is still flushed for GPU writes before it is read.
 - [Draw snapshot buffer descriptors](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) rewrite each affected array from element zero, preserving unchanged descriptors. MoltenVK 1.4.2 writes auxiliary buffer lengths at index `i` instead of `start + i` for partial array updates ([MVKDescriptorSet.mm, BufferAuxSize](https://github.com/KhronosGroup/MoltenVK/blob/v1.4.2/MoltenVK/MoltenVK/GPUObjects/MVKDescriptorSet.mm#L1051)). Per-element writes therefore let one buffer length replace another even when Vulkan buffer handles and ranges are correct.
 - The [driver](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) binds at most 262144 table images per pipeline, fewer under lower sampled-image limits; the rest fault when selected. A device without runtime descriptor arrays or variable-count bindings throws.
+- [Image storage tables](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - every bound element of a storage table is marked written and stored back after each dispatch, whether or not a lane wrote it. Two elements over the same bytes are therefore both stored back, and the order of their write-backs decides the result: PPSA26344's compute 0x80001e5f00 binds the stencil plane at 0x505f350000 twice, as R8_UINT in its own tile mode and as R8_UNORM in another. Rejecting the second writer of the same bytes per element, and per-element written bits from the GPU, are not implemented. The storage table binding is declared with its full capacity, so a set that holds one does not fit a chain descriptor pool and gets a dedicated pool. That capacity is a choice, not a device limit: the smallest of the sampled table capacity, 4096 and a quarter of `maxPerStageDescriptorStorageImages`. The sampled table capacity is not reduced by it, so a device with tight storage-image limits can fail layout validation. A storage element is rejected when its absolute index in the table reaches that capacity, even when few of the table's elements are storage, and it faults when a lane selects it. Atomic, packed, BY2/BY4 and dynamic-mip stores through a table still fault on use. `PresyncSurfaces` walks only the sampled table, so a store-only table's images are not presynced. Tables that mix sampled and storage elements, a T# that is both read and written through a table, non-uniform storage indexing and non-2D storage modes are not covered by tests.
 - [Image-table S#s](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) reading opaque black borders fault on selection: no runtime BC-swizzle pair check, even for valid swizzles 0/4 with direct or table T#s. Unselected entries do not fault. Table T#/direct S# keeps the direct check: only opaque-black swizzles moving alpha fault.
 - [Table S#s](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) that clamp to border fault only when selected: four variants cannot encode dynamic integer/float pairing. This also rejects otherwise-valid float pairs.
 - [Table T#s](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) paired with direct S#s fault when a paired border class differs from the decoded image class. Depth-bit views use float borders. Matching float pairs and inactive mismatches do not fault.

Both cases printed that the image storage table exceeds its capacity. They need different fixes, so each now has its own message with the set, the element's index in the set and the capacity. The debt entry now says that the index counts every table element before it in the set.

The copy still spans the whole fetch, but the bytes from `num_records * stride` onward read as zeros, so the out-of-range vertex is `(0, 0, 0, 0)`. Measured with `buffer_load_format_xyzw` (`idxen`) through the [hardware oracle](../HW_ORACLE.md) on RDNA2 gfx1036 for PPSA01325's word 3 `0x0004dfac` (`OOB_SELECT` 0) in #2241: indices 3, 4 and 5 over 3 records each return `00000000 00000000 00000000 00000000`, W included, unlike Vulkan `robustBufferAccess`, which returns `(0, 0, 0, 1)`. The zeros come from the record check, not from memory: stored values placed past the records are ignored, and a `num_records` 6 control returns them. `RESOURCE_LEVEL` 1, `OOB_SELECT` 1 and FORMAT 74 `32_32_32_FLOAT` give the same zeros, in wave32 and wave64; gfx1013 (the console) is not measured. `OOB_SELECT` 2 returns the stored values past the records and `OOB_SELECT` 3 compares `num_records` against the byte offset, both measured on the same setup in #2241; the two keep throwing past `num_records` here, since each needs its own rule. Zero-stride descriptors (`stride` 0) keep their separate byte-count check and are not covered here. Each out-of-range fetch is copied alone and outside the draw-snapshot cache, which is neither read nor written for it: a reused snapshot would carry another draw's bytes into the zero region, and a stored zero-padded copy would hand zeros to a later in-range draw at the same address. The valid prefix is still flushed for GPU writes before it is read.
 - [Draw snapshot buffer descriptors](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) rewrite each affected array from element zero, preserving unchanged descriptors. MoltenVK 1.4.2 writes auxiliary buffer lengths at index `i` instead of `start + i` for partial array updates ([MVKDescriptorSet.mm, BufferAuxSize](https://github.com/KhronosGroup/MoltenVK/blob/v1.4.2/MoltenVK/MoltenVK/GPUObjects/MVKDescriptorSet.mm#L1051)). Per-element writes therefore let one buffer length replace another even when Vulkan buffer handles and ranges are correct.
 - The [driver](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) binds at most 262144 table images per pipeline, fewer under lower sampled-image limits; the rest fault when selected. A device without runtime descriptor arrays or variable-count bindings throws.
-- [Image storage tables](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - every bound element of a storage table is marked written and stored back after each dispatch, whether or not a lane wrote it. Two elements over the same bytes are therefore both stored back, and the order of their write-backs decides the result: PPSA26344's compute 0x80001e5f00 binds the stencil plane at 0x505f350000 twice, as R8_UINT in its own tile mode and as R8_UNORM in another. Rejecting the second writer of the same bytes per element, and per-element written bits from the GPU, are not implemented. The storage table binding is declared with its full capacity, so a set that holds one does not fit a chain descriptor pool and gets a dedicated pool. That capacity is a choice, not a device limit: the smallest of the sampled table capacity, 4096 and a quarter of `maxPerStageDescriptorStorageImages`. The sampled table capacity is not reduced by it, so a device with tight storage-image limits can fail layout validation. A storage element is rejected when its absolute index in the table reaches that capacity, even when few of the table's elements are storage, and it faults when a lane selects it. Atomic, packed, BY2/BY4 and dynamic-mip stores through a table still fault on use. `PresyncSurfaces` walks only the sampled table, so a store-only table's images are not presynced. Tables that mix sampled and storage elements, a T# that is both read and written through a table, non-uniform storage indexing and non-2D storage modes are not covered by tests.

Unselected entries do not fault. Table T#/direct S# keeps the direct check: only opaque-black swizzles moving alpha fault.
 - [Table S#s](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) that clamp to border fault only when selected: four variants cannot encode dynamic integer/float pairing. This also rejects otherwise-valid float pairs.

Subject: [PATCH 0660/1000] fix(libkernel): treat a null deadline as an untimed
 lock in the timed pthread locks

pthread_rwlock_timedrdlock, pthread_rwlock_timedwrlock and
pthread_mutex_timedlock threw for a null abstime. FreeBSD's libthr
passes a null abstime on to the untimed kernel lock, so these calls
then wait like pthread_rwlock_rdlock, pthread_rwlock_wrlock and
pthread_mutex_lock.

Subject: [PATCH 0661/1000] feat(agc): count the render passes recorded draws
 begin and continue

DrawPassTotals returns, since the process started, how many recorded
draws began a render pass of their own or continued the previous draw's,
and how many flushed the queued DCC key stores or label stores before
themselves, for address-based draws and for the others. A draw is
address-based when its resources hold the allocation registry lease,
whether they were built for it or found in the draw cache.

The totals are kept with the [draws] line's (APS5_PROFILE_DRAW), so a
test or a harness can tell whether an address-based draw kept the open
pass without reading the 10-second report.

Subject: [PATCH 0662/1000] test(agc): check that draws reading through the BDA
 table share a render pass

agc_driver_address_passes draws a triangle twice onto a guest block, with pixel shaders that global_load_dword or global_store_dword through s[2:3], and reads DrawPassTotals for the address-based draws:
- --readers: two draws reading through the table share one render pass;
- --store-after-read: a draw storing through the table after one reading through it begins its own pass;
- --read-sees-store: a draw reading through the table what the previous draw stored sees the store, in a pass of its own.

Taken from c44c9a670 (perf/agc-bounded-address-passes) without its --store-beside-reads case, which needs that commit's store bounds.

Subject: [PATCH 0663/1000] fix(shader): flush v_fma_mix_f32 f16 sources by the
 f16 denormal field

v_fma_mix_f32 used its f16 sources unflushed in every mode. On RDNA2
(gfx1031) f16 denormal modes 0 and 2 flush each f16 source to a zero
of its sign, whatever the f32 denormal field, so
v_fma_mix_f32 0, 0, 0x0001 (all f16) is 0 there instead of 2^-24.

 - [Scalar f16 add, sub, subrev and mul denormals](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follow the `FLOAT_MODE` f16 denormal field at nearest-even: bit 0 preserves inputs and bit 1 preserves the result; otherwise a denormal is flushed to its signed zero. Measured on RDNA2 (gfx1036) with IEEE=0/1 and FP16_OVFL=0/1, over 32 operand pairs in all four denormal modes, including signed zeros, denormals, minimum normals, infinities and NaNs. Multiply detects tininess after rounding to 11 significant bits with an unbounded exponent, before gradual half packing: `0x3bff * 0x0400` flushes, while `0x3c01 * 0x03ff` rounds to `0x0400` and is kept. Directed rounding and ternary arithmetic keep their previous denormal lowering. Shaders without a known float mode keep the previous lowering. Scalar `v_sub_f16`/`v_subrev_f16` share `float16Binary` with add/mul and were measured on gfx1036 over the same operand set as add (1156 non-NaN-input rows per mode); NaN result bits still depend on the driver as recorded above.
 - [f16 unary, frexp and conversion denormals](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follow the `FLOAT_MODE` f16 denormal field: `v_ceil_f16`, `v_floor_f16`, `v_fract_f16`, `v_rcp_f16`, `v_rsq_f16`, `v_sqrt_f16`, `v_log_f16`, `v_exp_f16`, `v_sin_f16`, `v_frexp_mant_f16`, `v_frexp_exp_i16_f16`, `v_cvt_norm_i16_f16`, `v_cvt_norm_u16_f16` and `v_cvt_f32_f16` flush a denormal half input to its signed zero when bit 0 is clear (0 and 2), and the f16-result ones flush a denormal half result to its signed zero when bit 1 is clear (0 and 1), after the host rounds it to half. Measured on RDNA2 (gfx1036) at IEEE=0 and IEEE=1 with denorm16 0..3 over every non-NaN f16 input (63,490 rows per mode and instruction): the only mismatches are the 1-ULP driver differences of `v_exp_f16` (2 inputs) and `v_sin_f16` (14), which are the same with denormals kept. NaN inputs are not compared. `v_ldexp_f16` shares the input rule. `v_cvt_pknorm_i16_f16` and `v_cvt_pknorm_u16_f16` flush both half inputs by the same bit, measured on RDNA2 (gfx1030) over every f16 input (each half also negated in the other source) at IEEE=0 and IEEE=1 with denorm16 0..3 and at f16 rounding 1..3: every row matches. Shaders without a known float mode keep the previous lowering.
 - [Packed f16 NaN results](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (`v_pk_add/mul/fma/min/max_f16`) follow the hardware measured on RDNA2 (gfx1035) at IEEE=0 and IEEE=1 with f16 round-to-nearest-even and f16 denormals kept: with IEEE=1 a signaling NaN input is quieted and min/max return the other operand only for a quiet NaN; with IEEE=0 NaN inputs pass through unquieted and min/max ignore signaling. In `v_pk_fma_f16` an invalid product (inf * 0) gives the default NaN even when src2 is a NaN. A shader without a known float mode is translated as IEEE=0, the mode titles use; a mode with another f16 rounding or that flushes f16 denormals throws.
-- [f32 denormals](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follow the shader's `FLOAT_MODE` f32 denormal field (bits 5:4) when it flushes them (0, and shaders without a known float mode, as in the 0xc0 most titles use), measured on RDNA2 (gfx1035) over 1444 rows per instruction at IEEE=0 and IEEE=1. `v_add/sub/subrev/mul/mul_legacy/mullit/fma/fmac/fmamk/fmaak/min/max/min3/max3/med3/fract/floor/ceil/frexp_mant/sin/cos_f32` flush their f32 inputs and their result to a zero of the same sign (`v_mullit_f32` measured on RDNA2 (gfx1036) over 6907 rows per mode at IEEE=0 and IEEE=1, so a positive denormal src2 counts as zero); the f32 compares, `v_cvt_i32/u32/rpi_i32/flr_i32_f32`, `v_frexp_exp_i32_f32`, `v_cvt_f64_f32`, `v_cvt_f16_f32`, `v_cvt_pkrtz_f16_f32`, `v_cvt_pknorm_i16/u16_f32` and `v_cvt_pk_u8_f32` flush their f32 inputs. `v_div_scale_f32` flushes all three inputs to signed zeros, measured on RDNA2 (gfx1036) over 2744 operand triples per mode at IEEE=0 and IEEE=1 with f32 denormals flushed and kept; its scale-down behaviour and host denormal preservation remain incomplete. `v_div_fixup_f32` flushes its src1 and src2 and keeps a denormal src0 and result, measured on RDNA2 (gfx1036) over 6859 rows per mode at IEEE=0 and IEEE=1. Tininess is detected after rounding, measured on RDNA2 (gfx1036) for `v_mul_f32` and `v_mullit_f32` at IEEE=0 and IEEE=1: a product is flushed when its value rounded to 24 bits with an unbounded exponent is below 2^-126, so `0x3f7ffffe * 0x00800001` (2^-126 * (1 - 2^-46)) gives `0x00800000` and `0x3f7fffff * 0x00800000` (2^-126 * (1 - 2^-24)) gives zero. The check rounds in the f32 round mode of `FLOAT_MODE` (bits 1:0), measured in all four modes, while the products themselves are still rounded to nearest even. This applies to `v_mul_f32`, `v_mul_legacy_f32`, `v_mullit_f32`, and to `v_fma_f32`, `v_fmac_f32`, `v_fmamk_f32`, `v_fmaak_f32` and `v_fma_mix_f32` when the addend is zero; with a nonzero addend the fused result is kept, so an exact result just below 2^-126 that rounds to it is not flushed. In the three directed modes the check is computed exactly from the significands. To nearest even (0, the mode of shaders without a known float mode) one factor is multiplied by 2^64, which is exact below 2^64, and the product with the other factor is compared with 2^-62. That multiply is a plain `OpFMul` like the product, and no f32 rounding mode is requested in the SPIR-V, so the check relies on the driver rounding f32 to nearest even by default, as the products do, and a product that rounds up to 2^-126 is the emitted product. `v_fma_mix_f32` follows this rule with mixed f16/f32 sources too, measured on RDNA2 (gfx1036) with f16 in either multiplicand slot, low and high half selection, and an f32 or f16 zero addend: f32 `0x00801002` times f16 `0x3bff` gives `0x00800000` to nearest at IEEE=0 and IEEE=1, while the neighbours `0x00801001` and `0x00801003` give zero and `0x00800001`. The tiny-product boundary was also measured for both signs in all four f32 round modes at IEEE=0; f16 inputs retain their previous conversion and denormal handling. `v_fma_mixlo_f16` and `v_fma_mixhi_f16` flush their f32 sources too and keep a product below 2^-126, measured on RDNA2 (gfx1036). `v_mad_legacy_f32` and `v_mac_legacy_f32` flush their inputs, their product and their result in every mode, see its entry; their product is still checked for tininess on its exact value, so one below 2^-126 gives zero even when it rounds to 2^-126, as the console's separately rounded encoding is not measured at this boundary. Denormal modes 1 and 2 throw for the other instructions. Not covered, and not measurable on RDNA2 (no such opcodes) or not measured: `v_mac_f32`, `v_mad_f32`, `v_madak_f32` and `v_madmk_f32` (rounded separately), `v_dot2_f32_f16` and `v_div_fmas_f32` (on hardware `v_div_fmas_f32` flushes only its result), f32 interpolation and `ds_add_f32` keep the previous lowering; `ds_min/max/cmpst_f32` flush both operands by the field, see the LDS float atomics entry. With f32 denormals kept (3) the results depend on the driver's default denormal behaviour, as no `DenormPreserve` execution mode is requested; `v_ldexp_f32` and the f32 compares are the exceptions. `v_cmp_X_f32` and `v_cmpx_X_f32` compare the operands as sign-magnitude integers with the NaN cases handled apart, so a denormal is not read as zero, measured on RDNA2 (gfx1036) over 256 operand pairs per opcode at IEEE=0 and IEEE=1 with f32 denormals kept and flushed. `v_ldexp_f32` preserves subnormal inputs and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, measured on RDNA2 (gfx1036) over 2163 rows in each of the four round modes at IEEE=0 and IEEE=1. An overflow rounds like any other result (infinity, or the largest finite value when the mode rounds that sign toward zero). With f32 denormals flushed it flushes a subnormal input and result, measured over the same rows in each round mode at IEEE=0 only. A device whose driver splits `Fma` into a multiply and an add flushes a product below 2^-126 before adding a non-zero addend in `v_fma_f32` and `v_fmac_f32`: `0x1fffffff * 0x1fffffff + 0x00800000` gives `0x00800000` instead of the fused `0x00ffffff` on RADV RENOIR (Mesa 26.2.4), whose compiled shader has `v_mad_f32` and no `v_fma_f32`. [F32DenormalFlush](../../../core/libs/prx/libSceAgcDriver/tests/execution/F32DenormalFlush.cpp) accepts that sum on such a device.

The tiny-product boundary was also measured for both signs in all four f32 round modes at IEEE=0; Its f16 sources are flushed to a zero of their sign when bit 0 of the f16/f64 denormal field is clear (0 and 2), whatever the f32 field, measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) at IEEE=0 and IEEE=1 with f32 denormal modes 0 and 3 and f16 denormal modes 0 to 3, over 2744 triples of 14 halves with all three sources f16 and 1960 rows with an f32 multiplicand. `v_fma_mixlo_f16` and `v_fma_mixhi_f16` flush their f32 sources too and keep a product below 2^-126, measured on RDNA2 (gfx1036). `v_mad_legacy_f32` and `v_mac_legacy_f32` flush their inputs, their product and their result in every mode, see its entry; their product is still checked for tininess on its exact value, so one below 2^-126 gives zero even when it rounds to 2^-126, as the console's separately rounded encoding is not measured at this boundary.

[F32DenormalFlush](../../../core/libs/prx/libSceAgcDriver/tests/execution/F32DenormalFlush.cpp) accepts that sum on such a device.
 - [v_rcp, v_rsq, v_sqrt, v_log, v_exp, v_sin and v_cos](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (f32 and f16) use the driver's approximation for finite results, not the console's: the low bits can differ. Only NaN, invalid, zero and infinite results and the exact sin/cos zeros are chosen on the bits. Measured on RDNA2 (gfx1036) over every f16 input and 32,832 f32 inputs: RADV returns the hardware's bits for every input of rcp, rsq, sqrt and log and all but one of exp (f16 0x11c5, 1 ULP); NVIDIA (615.71.09) stays within 2 ULP except `v_log_f32` near 1.0 (next entry). [v_sin and v_cos](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) take the driver's sine or cosine of the radians of the exact cycle, except within 2^-12 of a turn from a zero of the function, where the result is the linear term of the exact distance to the zero: the hardware's constant 6.2831826 (0x40c90fd5) at the integers, which the hardware applies exactly to inputs below 2^-12 of a turn, and the f32 2π at the half and quarter turns, where the hardware is within 7 ULP of it. Outside those bands, a driver result more than 4 ULP from a Taylor series in turns of the exact cycle is replaced by the series, which is within 2 ULP of the true sine and cosine; the hardware is up to 9 ULP from them (gfx1035, 243,092 f32 inputs), so results stay within 13 ULP of the hardware on any driver. RADV returns the hardware's bits for every f16 input and for 32,422 sine and 32,486 cosine results of the 32,832 f32 inputs; the rest are 1 ULP off, except up to 14 ULP on either side of non-zero integers and up to 15 ULP beyond ±256 cycles, where the hardware's own reduction differs from the exact fraction, and up to 6 ULP inside the half- and quarter-turn bands. NVIDIA's own sine is within 1 ULP on 93% of the f32 inputs and up to 1,166 ULP off just outside the bands, its cosine within 163 ULP; the series replaces those results. A denormal f32 input with f32 denormals kept gives the hardware the input times 6.2831826; both hosts flush it.
 - [v_ldexp_f32 in denormal modes 1 and 2](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follows the `FLOAT_MODE` f32 denormal field: mode 1 keeps a subnormal input and flushes a result below 2^-126 to a zero of its sign in every f32 round mode, also one that rounds to 2^-126 at subnormal precision (`0x3fffffff` scaled by 2^-127); mode 2 flushes a subnormal input to a zero of its sign and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, as mode 3 does. Measured on RDNA2 (gfx1030, Radeon RX 6800, AMD Windows driver 32.0.21045.5002 through HIP) over 10,260 rows (54 inputs of both signs: zeros, subnormals, normals near 2^-126 and 1.0, the largest finite value, infinities and NaNs, each scaled by 190 exponents from -2^31 to 2^31-1) at IEEE=0 and IEEE=1 with each f32 denormal mode 0 to 3 and f32 round mode 0 to 3, DX10_CLAMP=1, f16 denormals kept, f16 round to nearest even and FP16_OVFL=0; with the `clamp` modifier the result is clamped as in the other modes. The PS5's gfx1013 is not measured.
 - [v_log_f32 and v_log_f16](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) keep the driver's log2 unless, for inputs within 1/8 of 1.0, it is more than 4 ULP from an eight-term series in x - 1, which then replaces it. `v_log_f16` goes through the same f32 lowering and is rounded to half. The series is evaluated for every `v_log` and chosen with `OpSelect` rather than a branch, so its seven fused multiply-adds and two multiplies are an unconditional cost. Measured on RDNA2 over all 3,145,728 f32 inputs within 1/8 of 1.0 (gfx1035, IEEE 0, f32 denormals flushed), the hardware is within 1 ULP of the correctly rounded log2 and the series within 2 ULP of it and within 3 ULP of the hardware (2 except at 0x3f752e47, 0x3f7baab0 and 0x3f7bc4fb), so a kept driver value is within 7 ULP of the hardware and a driver that returns the hardware's bits never triggers the gate; RADV (Mesa 26.2.4) returns the hardware's bits on the 9,280 such inputs measured on gfx1036; NVIDIA (615.71.09) was up to 23,947,836 ULP off at 1 - 2^-24 and is within 6 ULP inside the band after the change; outside it its own log2 stays up to 9 ULP off (measured up to 1.375). Over every f16 input, the change moves one `v_log_f16` result on NVIDIA (0x3bed, 1 ULP, onto the hardware's bits) and none on RADV.

Subject: [PATCH 0664/1000] fix(shader): flush v_div_fixup_f64 src1 and src2 by
 the f64 denormal field

On RDNA2 (gfx1031) f16/f64 denormal modes 0 and 2 flush the denominator
and numerator of v_div_fixup_f64 to a zero of the same sign and keep a
denormal quotient and result, as v_div_fixup_f32 does with the f32
field. The translation used them unflushed, so 0 / 2^-1074 gave 0
instead of the default NaN.

 - [SINT storage images](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) of 8- and 16-bit components saturate each stored 32-bit value to the component range, as adriadam10 measured for image stores on RDNA2 (gfx1035) in #944 (448 rows match); the PS5's gfx1013 is not measured. A D16 store sign-extends each 16-bit half before that saturation, as measured on RDNA2 (gfx1035) for `image_store d16` to all eight SINT formats with DMASK 0xf, 0x7, 0x5, 0x3, 0x2, 0xa and 0x1 (1792 rows match).
 - [`StoreTexel`](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) writes channel 1 of a two-channel format from the data slot whose DST_SEL is Y, for SINT and UINT alike. With DST_SEL X,Y,Z,W, gfx1035 writes it from the W slot, as adriadam10 measured in #944.
 - [v_ldexp_f16](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follows the `FLOAT_MODE` f16 denormal field: bit 0 preserves the half input and bit 1 the half result. Otherwise a denormal input is flushed to its signed zero, and a result whose exact scaled value is below the minimum normal (2^-14) is flushed to its signed zero before rounding, so `v_ldexp_f16 0x07ff, -1` gives +0 instead of 0x0400. Measured on RDNA2 (gfx1036) with round to nearest, IEEE 0 and 1 and denorm16 0..3, over every half magnitude 0x0000..0x0fff of both signs scaled by 2^-1 and 2^0 (16384 rows per mode): no mismatch. NaN and infinity handling and destination high-half preservation are unchanged. Shaders without a known float mode keep the previous lowering.
+- [v_div_fixup_f64](../../../core/shader/recompiler/Translation/src/Float64Instructions.cpp) flushes its src1 and src2 to a zero of the same sign when bit 0 of the `FLOAT_MODE` f16/f64 denormal field is clear (0 and 2) and keeps a denormal src0 and result in every mode, as `v_div_fixup_f32` does with the f32 field. Measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) over 1728 triples of 12 f64 values (zeros, denormals, the minimum normal, ±1, the largest finite value, infinity and quiet and signaling NaNs) at IEEE=0 and IEEE=1 with denorm16 0..3. Shaders without a known float mode keep the previous lowering. The PS5's gfx1013 is not measured.
 - [v_mullit_f32](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follows the hardware measured with the MODE register at IEEE=1 and denormals kept (a signaling NaN src0 is quieted only with IEEE=1, as measured at IEEE=0 too; a positive denormal src2 counts as positive); with f32 denormals flushed it follows the f32 denormals entry below, and denormal modes 1 and 2 throw.
 - [v_mad_legacy_f32 and v_mac_legacy_f32](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (VOP3 0x140, VOP2 0x06) round the product to f32 before the add, give a +0 product for a zero factor, and flush their f32 denormal sources, their product and their result to a zero of the same sign in every f32 denormal mode, an exception to the `FLOAT_MODE` model in [f32DenormalFlushFor](../../../core/shader/recompiler/Translation/src/VectorInstructions.cpp). Measured on gfx1010 (RX 5700 XT) with `tools/hw-oracle/template.s`, assembled by the AMD Windows driver's `amd_comgr_2.dll` and launched through its `amdhip64_6.dll` instead of `oracle.c` and ROCr, over the 32 rows of the five `FmaLegacy.cpp` and the four `MacLegacy.cpp` encodings: identical in wave32 and wave64 at IEEE 0 and 1 with f32 denormal modes 0 to 3, except that the two signaling NaN rows are quieted only with IEEE=1 (#1281, #1290). A sum of two zeros takes its sign on the bits (+0 unless both are -0), as lavapipe returned -0 for +0 + -0. The PS5's gfx1013 is not measured; LLVM decodes the encoding as `v_mad_legacy_f32` there, as on gfx1010. RDNA2 differs: on gfx1031 (RX 6700 XT, measured by pandather in #1281) the encoding is `v_fma_legacy_f32` and fused, with the same zero rule and denormal-source flush, so an RDNA2 measurement is not evidence for the console.
 - [v_fma_mixlo_f16 and v_fma_mixhi_f16](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) round the exact product-sum once to f16 with the f64 arithmetic of v_interp_p2_f16, so they need the Float64 capability. On RDNA2 (gfx1036) they follow the `FLOAT_MODE` f16 round and denormal fields, not the f32 round field: -1.5 * 2^-24 + 2^-126 from f32 sources (0xbfc00000, 0x33800000, 0x00800000) gives 0x8001 with f16 denormals kept and round to nearest even, 0x8000 with f16 denormals flushed and 0x8002 with f16 round toward -infinity. With f16 denormals kept, every f16 rounding mode is translated: the exact product-sum is rounded once in the mode's direction. All four modes match RDNA2 (gfx1036) on the 2,233 rows of the #2631 sweep, including `FLOAT_MODE` 0xcc (toward zero, used by ps5-opengl) and the exact cancellations toward -infinity; the PS5's gfx1013 is not measured. A result beyond 65504 becomes infinity or 65504 as IEEE 754 gives for the mode. Flushed f16 denormals still throw, and packed f16 still throws in every mode but round to nearest even with f16 denormals kept. `FP16_OVFL` set is not measured.

Subject: [PATCH 0665/1000] perf(agc): serve compute dispatches whose read-only
 buffers moved from the cached template

The content key of a compute stage leaves the base address and size of its
read-only guest buffers out, as a draw's key does. A template hit whose such
buffers moved is proved the way a draw's is (ShaderResources::MovedDispatchBuffers:
read-only, read in place when built, in reach, nothing pending over the new range)
and binds snapshots of the new ranges in a descriptor set of its own, kept with the
batch that records the dispatch. A refused proof builds the dispatch fresh, as
before. APS5_NO_DISPATCH_MOVE=1 turns the path off, APS5_DISPMOVE_MAX_KIB caps the
bytes snapshotted per dispatch.

A template whose storage image lies over memory that a depth surface covers is no
longer proved from stamps (fastRevalidate): cachedStorageTexture answers such a
binding with the plane's colour mirror, copied in from the depth image for every use,
and nothing stamps the appearance of a depth surface after the build. The full walk
decides, and a stale image can no longer be copied over the depth image.

Tests: Graphics.cpp (verdicts of the proof), execution DispatchMove (real device:
moved, exact, shortened, stored-over, own-output and written-range refusals) and
DispatchMoveDepth (a depth surface appearing over a template's plain storage image,
planes inside and outside the write watch, imports watched and unwatched).

PPSA15508/01.002.000 calls `sceSslLoadCert` with one 1,408-byte PEM CA and null client certificate/key arguments; this confirms that call shape, not console error behavior. Mbed TLS 3.6.7 parses DER/PEM chains and checks an optional client certificate/key pair. Imports are retained per context and committed together; a failed import preserves existing credentials. CA queries return independently owned snapshots; unload clears active credentials while outstanding snapshots remain valid. Appending repeated CA imports, snapshot lifetime across unload, memory overhead and error precedence have not been measured on a PS5. Invalid loads, malformed material, exhausted pools and unsupported keys throw rather than inventing console error codes. No root bundle is shipped; an empty context still returns `NOT_FOUND`. The existing null-list error, unknown-context behavior and legacy clearing of foreign raw CA lists remain unchanged. Certificate reader queries reflect active certificates or outstanding snapshots. Loading credentials neither starts a TLS connection nor authenticates a peer

The verify options, the minimum version and the ALPN protocol list are recorded on the connection; nothing reads them until `sceSslConnect` has a transport, and how the console applies them is unknown. The initial verify options are unknown and taken as 0. `sceSslSetMinSslVersion` accepts the `SceSslVersion` values SharpProspero lists, 0 (none) to 5 (TLS 1.2), and throws for others; whether the console accepts a TLS 1.3 value is unknown. `sceSslSetAlpn` stores the string up to its terminator and throws for a null list; whether the console expects a comma-separated list or the TLS wire format is unknown. `sceSslGetAlpnSelected` returns null, as no handshake completes. An unknown connection and a connection whose context was terminated throw, as for `sceSslSetVerifyCallback`

 - Keep the branch up to date with `main` and resolve conflicts yourself; rebasing and force-pushing is fine.
 - A pull request that conflicts with `main` and has no activity for 7 days is labeled `stale` with a reminder. It is not closed.
 - If a pull request needs another one first, say so on the checklist line (`Depends on: #N`; `none` otherwise).
+- If a pull request fixes a reported issue, write `Fixes #N` on its checklist line (`none` otherwise). GitHub closes the issue on merge, and the `fix error` label is added within the hour.
 - If a pull request fixes a stop or a wrong result seen on a title, name it on the checklist line with the title ID and its [Game bring-up](https://github.com/boykopovar/AnyPS5/discussions/categories/game-bring-up) discussion (`Unblocks: PPSA01325 #3232`; `none` otherwise). Reviewers review these first.
 - For GPU changes, list each tested GPU's vendor, model, driver and OS on the checklist line. CI runs GPU tests only on lavapipe, so reviewers may ask for a run on another vendor before merging.
 - Fixes a title needs go to `main` as pull requests. A Game bring-up discussion lists the open pull requests and local changes the title still needs; update the list when one is merged, closed or replaced.

Subject: [PATCH 0669/1000] feat(shader): translate packed f16 in the f16
 denormal modes that flush

v_pk_add/mul/fma/fmac/min/max_f16 threw in f16 denormal modes 0-2. On
RDNA2 (gfx1031) bit 6 clear flushes each denormal input lane to a zero
of its sign, and bit 7 clear flushes an add result below 2^-14 and a
mul or fma result whose exact value rounded to 11 significant bits
with an unbounded exponent is below 2^-14, as the scalar forms do;
min/max flush only their inputs. Packed f16 still throws for f16
rounding other than nearest even.

 - [v_div_fixup_f64](../../../core/shader/recompiler/Translation/src/Float64Instructions.cpp) flushes its src1 and src2 to a zero of the same sign when bit 0 of the `FLOAT_MODE` f16/f64 denormal field is clear (0 and 2) and keeps a denormal src0 and result in every mode, as `v_div_fixup_f32` does with the f32 field. Measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) over 1728 triples of 12 f64 values (zeros, denormals, the minimum normal, ±1, the largest finite value, infinity and quiet and signaling NaNs) at IEEE=0 and IEEE=1 with denorm16 0..3. Shaders without a known float mode keep the previous lowering. The PS5's gfx1013 is not measured.
 - [v_mullit_f32](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follows the hardware measured with the MODE register at IEEE=1 and denormals kept (a signaling NaN src0 is quieted only with IEEE=1, as measured at IEEE=0 too; a positive denormal src2 counts as positive); with f32 denormals flushed it follows the f32 denormals entry below, and denormal modes 1 and 2 throw.
 - [v_mad_legacy_f32 and v_mac_legacy_f32](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (VOP3 0x140, VOP2 0x06) round the product to f32 before the add, give a +0 product for a zero factor, and flush their f32 denormal sources, their product and their result to a zero of the same sign in every f32 denormal mode, an exception to the `FLOAT_MODE` model in [f32DenormalFlushFor](../../../core/shader/recompiler/Translation/src/VectorInstructions.cpp). Measured on gfx1010 (RX 5700 XT) with `tools/hw-oracle/template.s`, assembled by the AMD Windows driver's `amd_comgr_2.dll` and launched through its `amdhip64_6.dll` instead of `oracle.c` and ROCr, over the 32 rows of the five `FmaLegacy.cpp` and the four `MacLegacy.cpp` encodings: identical in wave32 and wave64 at IEEE 0 and 1 with f32 denormal modes 0 to 3, except that the two signaling NaN rows are quieted only with IEEE=1 (#1281, #1290). A sum of two zeros takes its sign on the bits (+0 unless both are -0), as lavapipe returned -0 for +0 + -0. The PS5's gfx1013 is not measured; LLVM decodes the encoding as `v_mad_legacy_f32` there, as on gfx1010. RDNA2 differs: on gfx1031 (RX 6700 XT, measured by pandather in #1281) the encoding is `v_fma_legacy_f32` and fused, with the same zero rule and denormal-source flush, so an RDNA2 measurement is not evidence for the console.

On RDNA2 (gfx1036) they follow the `FLOAT_MODE` f16 round and denormal fields, not the f32 round field: -1.5 * 2^-24 + 2^-126 from f32 sources (0xbfc00000, 0x33800000, 0x00800000) gives 0x8001 with f16 denormals kept and round to nearest even, 0x8000 with f16 denormals flushed and 0x8002 with f16 round toward -infinity. With f16 denormals kept, every f16 rounding mode is translated: the exact product-sum is rounded once in the mode's direction. All four modes match RDNA2 (gfx1036) on the 2,233 rows of the #2631 sweep, including `FLOAT_MODE` 0xcc (toward zero, used by ps5-opengl) and the exact cancellations toward -infinity; the PS5's gfx1013 is not measured. A result beyond 65504 becomes infinity or 65504 as IEEE 754 gives for the mode. Flushed f16 denormals still throw, and packed f16 still throws in every mode but round to nearest even with f16 denormals kept. `FP16_OVFL` set is not measured.

 - [Signaling NaN inputs](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) of the f32 and f16 unary instructions (`v_sqrt/rcp/rsq/log/exp/sin/cos/fract/floor/ceil/trunc/rndne/rcp_iflag/frexp_mant`), `v_ldexp_f32/f16`, `v_frexp_mant_f16`, `v_div_fixup_f32/f16` and `v_mullit_f32` are returned quieted only with IEEE=1 and unchanged with IEEE=0, measured on RDNA2 (gfx1035) in both modes, and so are those of the f64 forms (`v_sqrt/rcp/rsq/fract/floor/ceil/trunc/rndne/frexp_mant/ldexp/div_fixup_f64`) and `v_cvt_f64_f32`, measured on RDNA2 (gfx1036) in both modes; shaders without a known float mode follow IEEE=0. `v_pack_b32_f16` quiets each signaling NaN half by the same rule, measured on RDNA2 (gfx1036) in both modes. A signaling NaN result of `v_cubesc/cubetc/cubema_f32` is quieted by the same rule and keeps the sign the instruction gives it, measured on RDNA2 (gfx1036) in both modes. `v_add/sub/subrev/mul/fma/fmac/fmamk/fmaak/mul_legacy_f32` and `v_fma_mix_f32` with f32 sources choose their NaN result on the bits, measured over 1000 operand triples in both modes: the first NaN source in operand order after its modifiers (the subtrahend negated, as the hardware adds its negation), quieted only with IEEE=1, or the default NaN 0xffc00000 for an invalid operation; in the fma forms an invalid product (inf * 0) gives the default NaN even when src2 is a NaN, and in the legacy forms a zero factor makes the product 0 even when the other factor is a NaN (a NaN src2 still wins). `v_mad_legacy_f32` and `v_mac_legacy_f32` follow the same rule with their separately rounded product, as measured on gfx1010 (#1281, #1290): a NaN source quieted only with IEEE=1, inf - inf giving 0xffc00000, the zero rule hiding a NaN factor and a NaN src2 winning. The f16 and f64 arithmetic, `v_fma_mix_f32` with f16 sources and the separately rounded mad/mac forms (not measurable on RDNA2) follow the same rule on hardware but their NaN bits are left to the driver. `v_cvt_f16_f32`, `v_cvt_f32_f64`, `v_dot2_f32_f16`, `v_fma_mixlo_f16` and `v_fma_mixhi_f16` always quiet and `v_div_scale_f32` never does: the f32 signaling NaN 0x7f812345 as src0 or src2 gives 0x7e09 from mixlo and mixhi at IEEE=0 and IEEE=1 on RDNA2 (gfx1036), where `v_fma_mix_f32` gives 0x7f812345 at IEEE=0 and 0x7fc12345 at IEEE=1. The payload of an f16 NaN source of mixlo and mixhi is left to the driver's f16 to f32 conversion, which NVIDIA replaces.
 - [Scalar f16 add, sub, subrev and mul denormals](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follow the `FLOAT_MODE` f16 denormal field at nearest-even: bit 0 preserves inputs and bit 1 preserves the result; otherwise a denormal is flushed to its signed zero. Measured on RDNA2 (gfx1036) with IEEE=0/1 and FP16_OVFL=0/1, over 32 operand pairs in all four denormal modes, including signed zeros, denormals, minimum normals, infinities and NaNs. Multiply detects tininess after rounding to 11 significant bits with an unbounded exponent, before gradual half packing: `0x3bff * 0x0400` flushes, while `0x3c01 * 0x03ff` rounds to `0x0400` and is kept. `v_fma_f16`, `v_fmac_f16`, `v_fmamk_f16` and `v_fmaak_f16` follow the same field at nearest-even: inputs are flushed when bit 0 is clear, and the result is flushed when bit 1 is clear if the exact product-sum rounded to 11 significant bits with an unbounded exponent is below 2^-14, so `0x0400 * 0x0400 + 0x8400` rounds to `0x8400` and is kept. Measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) at IEEE=0 and IEEE=1 with denorm16 0..3 over 5075 operand triples of `v_fma_f16` and `v_fmac_f16` (4000 from 20 halves around the denormal range, 75 whose product-sum lies just below 2^-14 and 1000 random), and over the first 4075 of them for `v_fmamk_f16` and `v_fmaak_f16`, FP16_OVFL=1, the clamp, neg and abs modifiers and op_sel. Directed rounding and `v_fma_mixlo/mixhi_f16` keep their previous denormal lowering. Shaders without a known float mode keep the previous lowering. Scalar `v_sub_f16`/`v_subrev_f16` share `float16Binary` with add/mul and were measured on gfx1036 over the same operand set as add (1156 non-NaN-input rows per mode); NaN result bits still depend on the driver as recorded above.
 - [f16 unary, frexp and conversion denormals](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follow the `FLOAT_MODE` f16 denormal field: `v_ceil_f16`, `v_floor_f16`, `v_fract_f16`, `v_rcp_f16`, `v_rsq_f16`, `v_sqrt_f16`, `v_log_f16`, `v_exp_f16`, `v_sin_f16`, `v_frexp_mant_f16`, `v_frexp_exp_i16_f16`, `v_cvt_norm_i16_f16`, `v_cvt_norm_u16_f16` and `v_cvt_f32_f16` flush a denormal half input to its signed zero when bit 0 is clear (0 and 2), and the f16-result ones flush a denormal half result to its signed zero when bit 1 is clear (0 and 1), after the host rounds it to half. Measured on RDNA2 (gfx1036) at IEEE=0 and IEEE=1 with denorm16 0..3 over every non-NaN f16 input (63,490 rows per mode and instruction): the only mismatches are the 1-ULP driver differences of `v_exp_f16` (2 inputs) and `v_sin_f16` (14), which are the same with denormals kept. NaN inputs are not compared. `v_ldexp_f16` shares the input rule. `v_cvt_pknorm_i16_f16` and `v_cvt_pknorm_u16_f16` flush both half inputs by the same bit, measured on RDNA2 (gfx1030) over every f16 input (each half also negated in the other source) at IEEE=0 and IEEE=1 with denorm16 0..3 and at f16 rounding 1..3: every row matches. Shaders without a known float mode keep the previous lowering.
 - [v_div_fixup_f16](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) flushes its src1 and src2 to a zero of the same sign when bit 0 of the `FLOAT_MODE` f16 denormal field is clear (0 and 2) and keeps a denormal src0 and result in every mode, as `v_div_fixup_f32` does with the f32 field. Measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) over 6859 triples of 19 halves (zeros, denormals, minimum normals, ±0.5, ±1, the largest finite value, infinities and quiet and signaling NaNs) at IEEE=0 and IEEE=1 with denorm16 0..3 and FP16_OVFL 0 and 1, also with neg and abs source modifiers and with op_sel high halves. Shaders without a known float mode keep the previous lowering. The PS5's gfx1013 is not measured.
-- [Packed f16 NaN results](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (`v_pk_add/mul/fma/min/max_f16`) follow the hardware measured on RDNA2 (gfx1035) at IEEE=0 and IEEE=1 with f16 round-to-nearest-even and f16 denormals kept: with IEEE=1 a signaling NaN input is quieted and min/max return the other operand only for a quiet NaN; with IEEE=0 NaN inputs pass through unquieted and min/max ignore signaling. In `v_pk_fma_f16` an invalid product (inf * 0) gives the default NaN even when src2 is a NaN. A shader without a known float mode is translated as IEEE=0, the mode titles use; a mode with another f16 rounding or that flushes f16 denormals throws.
+- [Packed f16 NaN results](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (`v_pk_add/mul/fma/min/max_f16`) follow the hardware measured on RDNA2 (gfx1035) at IEEE=0 and IEEE=1 with f16 round-to-nearest-even and f16 denormals kept: with IEEE=1 a signaling NaN input is quieted and min/max return the other operand only for a quiet NaN; with IEEE=0 NaN inputs pass through unquieted and min/max ignore signaling.

A shader without a known float mode is translated as IEEE=0, the mode titles use; a mode with another f16 rounding throws. In the f16 denormal modes that flush, each denormal input lane is flushed to a zero of its sign when bit 0 of the field is clear (0 and 2), so `inf * 0x0001` is an invalid product there, and when bit 1 is clear (0 and 1) a `v_pk_add_f16` result below 2^-14, or a `v_pk_mul_f16`, `v_pk_fma_f16` or `v_pk_fmac_f16` result whose exact value rounded to 11 significant bits with an unbounded exponent is below 2^-14, is flushed to a zero of its sign; `v_pk_min/max_f16` flush only their inputs. The native f16x2 add and multiply is not used while results are flushed. Measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) at IEEE=0 and IEEE=1 with denorm16 0..3, over 19,192 to 162,204 lanes per instruction with op_sel, op_sel_hi, neg_lo, neg_hi and clamp variants and products and sums at the 2^-14 boundary.
 - [f32 denormals](../../../core/shader/recompiler/Translation/src/TranslationContext/OperandAccess.cpp) follow the shader's `FLOAT_MODE` f32 denormal field (bits 5:4) when it flushes them (0, and shaders without a known float mode, as in the 0xc0 most titles use), measured on RDNA2 (gfx1035) over 1444 rows per instruction at IEEE=0 and IEEE=1. `v_add/sub/subrev/mul/mul_legacy/mullit/fma/fmac/fmamk/fmaak/min/max/min3/max3/med3/fract/floor/ceil/frexp_mant/sin/cos_f32` flush their f32 inputs and their result to a zero of the same sign (`v_mullit_f32` measured on RDNA2 (gfx1036) over 6907 rows per mode at IEEE=0 and IEEE=1, so a positive denormal src2 counts as zero); the f32 compares, `v_cvt_i32/u32/rpi_i32/flr_i32_f32`, `v_frexp_exp_i32_f32`, `v_cvt_f64_f32`, `v_cvt_f16_f32`, `v_cvt_pkrtz_f16_f32`, `v_cvt_pknorm_i16/u16_f32` and `v_cvt_pk_u8_f32` flush their f32 inputs. `v_div_scale_f32` flushes all three inputs to signed zeros, measured on RDNA2 (gfx1036) over 2744 operand triples per mode at IEEE=0 and IEEE=1 with f32 denormals flushed and kept; its scale-down behaviour and host denormal preservation remain incomplete. `v_div_fixup_f32` flushes its src1 and src2 and keeps a denormal src0 and result, measured on RDNA2 (gfx1036) over 6859 rows per mode at IEEE=0 and IEEE=1. Tininess is detected after rounding, measured on RDNA2 (gfx1036) for `v_mul_f32` and `v_mullit_f32` at IEEE=0 and IEEE=1: a product is flushed when its value rounded to 24 bits with an unbounded exponent is below 2^-126, so `0x3f7ffffe * 0x00800001` (2^-126 * (1 - 2^-46)) gives `0x00800000` and `0x3f7fffff * 0x00800000` (2^-126 * (1 - 2^-24)) gives zero. The check rounds in the f32 round mode of `FLOAT_MODE` (bits 1:0), measured in all four modes, while the products themselves are still rounded to nearest even. This applies to `v_mul_f32`, `v_mul_legacy_f32`, `v_mullit_f32`, and to `v_fma_f32`, `v_fmac_f32`, `v_fmamk_f32`, `v_fmaak_f32` and `v_fma_mix_f32` when the addend is zero; with a nonzero addend the fused result is kept, so an exact result just below 2^-126 that rounds to it is not flushed. In the three directed modes the check is computed exactly from the significands. To nearest even (0, the mode of shaders without a known float mode) one factor is multiplied by 2^64, which is exact below 2^64, and the product with the other factor is compared with 2^-62. That multiply is a plain `OpFMul` like the product, and no f32 rounding mode is requested in the SPIR-V, so the check relies on the driver rounding f32 to nearest even by default, as the products do, and a product that rounds up to 2^-126 is the emitted product. `v_fma_mix_f32` follows this rule with mixed f16/f32 sources too, measured on RDNA2 (gfx1036) with f16 in either multiplicand slot, low and high half selection, and an f32 or f16 zero addend: f32 `0x00801002` times f16 `0x3bff` gives `0x00800000` to nearest at IEEE=0 and IEEE=1, while the neighbours `0x00801001` and `0x00801003` give zero and `0x00800001`. The tiny-product boundary was also measured for both signs in all four f32 round modes at IEEE=0; Its f16 sources are flushed to a zero of their sign when bit 0 of the f16/f64 denormal field is clear (0 and 2), whatever the f32 field, measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) at IEEE=0 and IEEE=1 with f32 denormal modes 0 and 3 and f16 denormal modes 0 to 3, over 2744 triples of 14 halves with all three sources f16 and 1960 rows with an f32 multiplicand. `v_fma_mixlo_f16` and `v_fma_mixhi_f16` flush their f32 sources too and keep a product below 2^-126, measured on RDNA2 (gfx1036). `v_mad_legacy_f32` and `v_mac_legacy_f32` flush their inputs, their product and their result in every mode, see its entry; their product is still checked for tininess on its exact value, so one below 2^-126 gives zero even when it rounds to 2^-126, as the console's separately rounded encoding is not measured at this boundary. Denormal modes 1 and 2 throw for the other instructions. Not covered, and not measurable on RDNA2 (no such opcodes) or not measured: `v_mac_f32`, `v_mad_f32`, `v_madak_f32` and `v_madmk_f32` (rounded separately), `v_dot2_f32_f16` and `v_div_fmas_f32` (on hardware `v_div_fmas_f32` flushes only its result), f32 interpolation and `ds_add_f32` keep the previous lowering; `ds_min/max/cmpst_f32` flush both operands by the field, see the LDS float atomics entry. With f32 denormals kept (3) the results depend on the driver's default denormal behaviour, as no `DenormPreserve` execution mode is requested; `v_ldexp_f32` and the f32 compares are the exceptions. `v_cmp_X_f32` and `v_cmpx_X_f32` compare the operands as sign-magnitude integers with the NaN cases handled apart, so a denormal is not read as zero, measured on RDNA2 (gfx1036) over 256 operand pairs per opcode at IEEE=0 and IEEE=1 with f32 denormals kept and flushed. `v_ldexp_f32` preserves subnormal inputs and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, measured on RDNA2 (gfx1036) over 2163 rows in each of the four round modes at IEEE=0 and IEEE=1. An overflow rounds like any other result (infinity, or the largest finite value when the mode rounds that sign toward zero). With f32 denormals flushed it flushes a subnormal input and result, measured over the same rows in each round mode at IEEE=0 only. A device whose driver splits `Fma` into a multiply and an add flushes a product below 2^-126 before adding a non-zero addend in `v_fma_f32` and `v_fmac_f32`: `0x1fffffff * 0x1fffffff + 0x00800000` gives `0x00800000` instead of the fused `0x00ffffff` on RADV RENOIR (Mesa 26.2.4), whose compiled shader has `v_mad_f32` and no `v_fma_f32`. [F32DenormalFlush](../../../core/libs/prx/libSceAgcDriver/tests/execution/F32DenormalFlush.cpp) accepts that sum on such a device.
 - [v_rcp, v_rsq, v_sqrt, v_log, v_exp, v_sin and v_cos](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) (f32 and f16) use the driver's approximation for finite results, not the console's: the low bits can differ. Only NaN, invalid, zero and infinite results and the exact sin/cos zeros are chosen on the bits. Measured on RDNA2 (gfx1036) over every f16 input and 32,832 f32 inputs: RADV returns the hardware's bits for every input of rcp, rsq, sqrt and log and all but one of exp (f16 0x11c5, 1 ULP); NVIDIA (615.71.09) stays within 2 ULP except `v_log_f32` near 1.0 (next entry). [v_sin and v_cos](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterMath.cpp) take the driver's sine or cosine of the radians of the exact cycle, except within 2^-12 of a turn from a zero of the function, where the result is the linear term of the exact distance to the zero: the hardware's constant 6.2831826 (0x40c90fd5) at the integers, which the hardware applies exactly to inputs below 2^-12 of a turn, and the f32 2π at the half and quarter turns, where the hardware is within 7 ULP of it. Outside those bands, a driver result more than 4 ULP from a Taylor series in turns of the exact cycle is replaced by the series, which is within 2 ULP of the true sine and cosine; the hardware is up to 9 ULP from them (gfx1035, 243,092 f32 inputs), so results stay within 13 ULP of the hardware on any driver. RADV returns the hardware's bits for every f16 input and for 32,422 sine and 32,486 cosine results of the 32,832 f32 inputs; the rest are 1 ULP off, except up to 14 ULP on either side of non-zero integers and up to 15 ULP beyond ±256 cycles, where the hardware's own reduction differs from the exact fraction, and up to 6 ULP inside the half- and quarter-turn bands. NVIDIA's own sine is within 1 ULP on 93% of the f32 inputs and up to 1,166 ULP off just outside the bands, its cosine within 163 ULP; the series replaces those results. A denormal f32 input with f32 denormals kept gives the hardware the input times 6.2831826; both hosts flush it.
 - [v_ldexp_f32 in denormal modes 1 and 2](../../../core/shader/recompiler/Translation/src/FloatInstructions.cpp) follows the `FLOAT_MODE` f32 denormal field: mode 1 keeps a subnormal input and flushes a result below 2^-126 to a zero of its sign in every f32 round mode, also one that rounds to 2^-126 at subnormal precision (`0x3fffffff` scaled by 2^-127); mode 2 flushes a subnormal input to a zero of its sign and rounds a subnormal result in the f32 round mode of `FLOAT_MODE`, as mode 3 does. Measured on RDNA2 (gfx1030, Radeon RX 6800, AMD Windows driver 32.0.21045.5002 through HIP) over 10,260 rows (54 inputs of both signs: zeros, subnormals, normals near 2^-126 and 1.0, the largest finite value, infinities and NaNs, each scaled by 190 exponents from -2^31 to 2^31-1) at IEEE=0 and IEEE=1 with each f32 denormal mode 0 to 3 and f32 round mode 0 to 3, DX10_CLAMP=1, f16 denormals kept, f16 round to nearest even and FP16_OVFL=0; with the `clamp` modifier the result is clamped as in the other modes. The PS5's gfx1013 is not measured.

 - `--trace-imports` ([entry stub](../../../core/relinker/elfpatcher/src/windows/WindowsEntryStubBuilder.cpp)) exists for Windows output only. Only imports bound through a PLT slot, or through a GOT slot whose symbol is a function, are traced; a function reached through any other relocation, or looked up at run time with `sceKernelDlsym`, is not, and neither are weak imports or the imports of modules loaded at run time
 
 - [ANDN lowering](../../../core/relinker/codegen/src/x86/AndnLowering.cpp) uses scalar NOT and AND for 32- and 64-bit register and memory operands under `--to-rosetta`, following the ANDN entry in [Intel SDM volume 2A](https://cdrdv2-public.intel.com/812383/253666-sdm-vol-2a.pdf). SF and ZF follow the result, CF and OF clear, and AF and PF are undefined. The scratch register is saved below the 128-byte red zone. A 64-bit stack-relative displacement that exceeds signed disp32 after reserving the spill frame throws; other BMI instructions are not lowered. The M1 test covers register overlap, RSP operands, memory addressing, RIP relocation, flags and red-zone preservation; precise fault delivery inside a spill sequence has not been verified.
-- On macOS, [libc.prx](../../../core/relinker/elfpatcher/src/macos/MacOsMachOPatcher.cpp) is a dependency only when `libSceLibcInternal.prx` is needed, so a program that needs only `libkernel.prx` cannot resolve the libkernel functions that AnyPS5 exports from libc.prx, such as `__error`. Windows also lists libc.prx for `libkernel.prx`.

Subject: [PATCH 0671/1000] fix(main): retry temp dir cleanup in
 loadexec_arguments on Windows

Run 39019245350 (main f05fc7d953) failed loadexec_arguments with WinError 5 on
unlinking guest_loadexec_host.prx in TemporaryDirectory cleanup: the exited
guest process still held the module briefly. #7038 does not touch it (0 of 25
earlier main builds failed). Retry the removal for up to 10 s.

Subject: [PATCH 0673/1000] fix(agc): compare moved dispatch buffers at their
 build-time clamped size

A read-only V# the build clamps (size above the descriptor range limit cut to the
mapped end, stride overhang cut to the allocation end) was compared with the template
by its raw size, so an unchanged buffer counted as moved, was refused over the limit
and the dispatch rebuilt every time; a moved one with an overhang was snapshotted past
the allocation end. The build and the move proof now take the range from one function
(ShaderResources::guestBufferBytes), compare clamped with clamped and snapshot the
clamped range.

An overlay without a descriptor set is refused like one that could not be made, and
recording one throws instead of binding the template's set.

Subject: [PATCH 0674/1000] test(agc): skip the emulated color compare clamp
 cases without MinLod

The offset cases compile `image_sample_cb_cl_o`, whose LOD clamp the emitter
reaches only through the device's `shaderResourceMinLod`; without it the
emitter refuses the shader (the gate #388 left in place). The test had no
capability guard, so on such a device every one of those cases failed at the
first of them, `point, wrap with negative offsets`, instead of skipping them
as `ImageSampleLodClamp` and `ImageSampleBiasA16` already do.

Found on llvmpipe (Mesa 25.0.7, Debian 13), which lacks the feature that
lavapipe reports from Mesa 25.2.8: `agc_driver_emulated_color_compare` and
its `_srgb_decode` variant both failed. The other cases still run; the note
names the cases that were skipped.

Subject: [PATCH 0675/1000] feat(libc): implement sceLibcBacktraceSelf on Linux

PPSA28997 (IL2CPP) calls sceLibcBacktraceGetBufferSize and
sceLibcBacktraceSelf. On Linux the host call stack is captured with
backtrace and each frame is resolved to its module and offset with
dladdr, then written as a linked list of frame records. The record
layout is inferred and listed in TechnicalDebt. Windows throws.

 ### Unknown function info
 
+- [sceLibcBacktraceGetBufferSize, sceLibcBacktraceSelf](../../core/libs/prx/libc/src/Backtrace.cpp) (libc) - signatures and frame record layout inferred from a title (next pointer, u32 module offset, module name at +0x10); the u32 at +0xC is unknown and written as 0. Module names are host file names without the `.guest.prx` suffix, so their case may differ from the PS5 module name. Windows throws
 - [fdopen](../../../core/libs/prx/libc/src/FileAndHeap.cpp) (libc) validates descriptor access modes as FreeBSD 11.4 [fdopen.c](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdio/fdopen.c) does: a requested mode incompatible with a descriptor not opened for both reading and writing returns null with `EINVAL`, leaving the descriptor open. Windows reads the handle's granted access through the same host helper as `fcntl(F_GETFL)`; a closed descriptor returns null with `EBADF`. Console behavior is unverified.
 - [scriptingGetMem, scriptingFreeMem](../../../core/libs/prx/libc/src/ApplicationHeap.cpp) (libc) - runtime allocator hooks for Unity titles. The allocation signature `(alignment, size)`, minimum alignment 16 and null result for a non-power-of-two alignment follow [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/df5b9b92be7dfd463b47756b707d6d356a9f0550/src/libs/libKernel.cpp); the free hook's one-pointer signature follows [Raeen's recorded contract](https://github.com/Whoisraeen/Raeen/blob/2db56923204b89719916b95e29c2f3c4e1d9f90b/docs/unity-dlsym-blocker.md). Both use the registered application allocator. No console measurement; null allocation returns null and other allocator errors throw.

 - [sceNetConnect to AF_UNSPEC](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) dissolves a datagram association as FreeBSD 11.4's `udp_disconnect()` does, which resets the local address to the wildcard address and keeps the port. On Linux a socket bound to an explicit port keeps its local address as well (`127.0.0.1:<port>` stays `127.0.0.1:<port>`), because a bound socket cannot be bound again; one bound to port 0 is bound again to the wildcard address with the port it had
 - [sceNetSetsockopt](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) sets `SO_RCVTIMEO` and `SO_SNDTIMEO` as the host socket's timeouts. On Windows a receive or send on a stream socket that times out fails with `ETIMEDOUT`, where FreeBSD returns `EAGAIN` or the partial count: Winsock leaves the connection in an indeterminate state after a timeout and reports no partial count ([SOL_SOCKET options](https://learn.microsoft.com/en-us/windows/win32/winsock/sol-socket-socket-options)), so FreeBSD's behaviour needs the timeout waited for without the host option. A receive on a datagram socket that times out fails with `EAGAIN`
 - [sceNetSetsockopt, sceNetGetsockopt](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) take `SO_SNDTIMEO` and `SO_RCVTIMEO` (0x1005, 0x1006) as a 16-byte `struct timeval`, as FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/d106002967eff712894ab8b5337bbbff106ce5e0/sys/kern/uipc_socket.c#L2657-L2690) do, and Sony's 0x1105 and 0x1106 as an `int` of microseconds. A [console log of ProsperoLight](https://github.com/blackbearreloaded/ProsperoLight/issues/49) (firmware 12.20) shows receives timing out every 100 ms after it gave 0x1006 a `{0, 100000}` timeval. The errors for a value shorter than a timeval (`EINVAL`) or out of range (`EDOM`), and `sceNetGetsockopt` cutting the timeval to the caller's length, follow FreeBSD's `sooptcopyin` and `sooptcopyout` and are not measured on a console
+- [sceNetSetsockopt](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) stores `SO_ONESBCAST` (`0x10000`, [shadPS4's `ORBIS_NET_SO_ONESBCAST`](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/net/net_types.h)) per socket and `sceNetGetsockopt` reads back the value that was set, as shadPS4 does; PPSA34501 sets it and crashes later when it fails with `EOPNOTSUPP`. Sends ignore it. FreeBSD 11.4's [ip(4)](https://man.freebsd.org/cgi/man.cgi?manpath=FreeBSD+11.4-RELEASE&query=ip&sektion=4) documents the like-named `IPPROTO_IP` option `IP_ONESBCAST`: a datagram sent to an interface's directed broadcast address, such as 192.168.2.255, leaves through that interface with its destination rewritten to 255.255.255.255, and only on a socket allowed to set `SO_BROADCAST`. Here host routing selects the outgoing interface and the destination is not rewritten. shadPS4 also leaves sends unchanged, and its [TODO](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/net/net.cpp#L2467-L2470) reads the option the other way round: a send to 255.255.255.255 would be converted to the interface's broadcast address. Whether the console's `SOL_SOCKET` option behaves like `IP_ONESBCAST`, and what it reads back, is not verified on hardware. FreeBSD 11.4's `sogetopt()` reads several boolean socket options back as their flag bit (`so_options & optname`, `sys/kern/uipc_socket.c`), not as the value set; whether the console does so for `0x10000` is unknown
 - [sceNetGetsockopt](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) reads `SO_ERROR` from the host socket. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `sceNetConnect`; a second failure with the same code on the same socket without a `sceNetConnect` in between would be hidden.
 - [sceNetSendmsg and sceNetRecvmsg](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) copy the scatter/gather list through one host buffer and accept only the flags `sceNetSend`/`sceNetRecv` accept. Sending control data throws; a receive never returns control data (`msg_controllen` 0), since no socket option that queues it is supported
 - [MSG_DONTWAIT](../../../core/libs/prx/libSceNet/Export.cpp) (libSceNet) in `sceNetSend`, `sceNetSendto`, `sceNetRecv`, `sceNetRecvfrom`, `sceNetRecvmsg` and `sceNetSendmsg` makes that one call non-blocking through the host's `MSG_DONTWAIT`, as FreeBSD 11.4's `soreceive_generic` returns `EWOULDBLOCK` for it (`sys/kern/uipc_socket.c`); the value `0x80` is FreeBSD's (`sys/sys/socket.h`) and [shadPS4's](https://github.com/shadps4-emu/shadPS4/blob/e0a466753a1aacbc8db8253be685bf7ab4d9daae/src/core/libraries/net/net_types.h#L104). Winsock has no per-call non-blocking flag, so on Windows these calls still fail with `EOPNOTSUPP` for it

Subject: [PATCH 0681/1000] fix(libc): translate the host errno of a failed
 fopen

fopen left the host's errno in place when the host open failed, so on Linux a symlink loop reached the title as 40 and an over-long name as 36, which are EMSGSIZE and EINPROGRESS on FreeBSD. GuestErrnoFromHost_nid_no_patch maps the host value to FreeBSD 11.4's: 1 to 34 are shared except EAGAIN (35), and ELOOP, ENAMETOOLONG, ENOTEMPTY, EDQUOT, EOVERFLOW and EDEADLK get their FreeBSD numbers; anything else is EIO.

Subject: [PATCH 0682/1000] fix(libc): translate the host errno of a failed
 freopen

freopen closed the stream and returned the host's errno from the failed reopen as is, with the same Linux numbers for a symlink loop or an over-long name as fopen had. It now passes it through GuestErrnoFromHost_nid_no_patch.

Subject: [PATCH 0683/1000] fix(libc): return the open error from fopen_s
 instead of ENOENT

fopen_s returned ENOENT for every failed open, including an invalid mode, a directory opened for writing and the loop and long-name cases. C11 K.3.5.2.1 only asks for a nonzero value; Microsoft's CRT, which shares Dinkumware's library, returns errno. fopen_s now returns the errno fopen set.

Calls are also counted per traced target since start-up; an import bound to a target already traced under another name is counted under the first name.

 - [app0.zar](../../../core/libs/prx/libc/src/AppArchive.cpp) (libc) - a [ZArchive](https://github.com/Exzap/ZArchive) beside `app0/` is a read-only layer under it: a path missing from `app0/` is looked up in the archive, case-insensitively. It is not a console format; titles ship their files in a PFS image instead. Resolving an archive-only path through any call other than the archive-aware libkernel ones throws, so `fopen`, `stat`, `access`, `opendir` and the rest do not read the archive yet, and `opendir` of a directory that exists in both places, `app0/` itself included, and `fdopen` of an archived descriptor throw instead of missing its entries or reading the null device. A damaged compressed block throws instead of returning `EIO`
+- [fopen_s](../../../core/libs/prx/libc/src/FileAndHeap.cpp) (libc) - returns the errno of the failed open, as C11 K.3.5.2.1 leaves the nonzero value open and Microsoft's CRT returns errno; the console's Dinkumware `fopen_s` is not verified

Subject: [PATCH 0685/1000] fix(libkernel): answer F_GETLK with F_UNLCK on
 Linux and macOS

fcntl threw for F_GETLK with an F_UNLCK request on the hosts that use POSIX locks, as Linux's F_GETLK rejects that type. FreeBSD 11.4's kern_fcntl accepts it and lf_getlock reports the first overlapping lock that lf_blocks lets conflict: another owner's lock, one of the two being a write lock. For an F_UNLCK request that is exactly another owner's write lock, the same set an F_RDLCK request finds, so the host is asked with F_RDLCK and the reply is written back as for the other types.

 - [sigaction](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) records the handler, flags and mask of every signal from 1 to 128 and reports them back, following FreeBSD's `sigaction` (`EINVAL` for other signals, and for a handler on `SIGKILL` or `SIGSTOP`); `signal` records its handler with `SA_RESTART`, as FreeBSD's libc does. Only handlers without `SA_SIGINFO` on the signals `signal` already delivers (`SIGINT`, `SIGILL`, `SIGABRT`, `SIGFPE`, `SIGSEGV`, `SIGTERM`) run, the same way `signal` handlers do; their mask and flags are not applied. `SA_SIGINFO` handlers are recorded but never called, since that needs FreeBSD's `siginfo_t` and `ucontext_t`, and neither are the handlers of other signals (`SIGBUS`, `SIGHUP`, ...), whether they are set by `sigaction` or by `signal`, which records them too (every number from 1 to 128, with `SA_RESTART` and an empty mask replacing what `sigaction` stored; `SIGKILL` and `SIGSTOP` accept only the default handler in both calls, as in FreeBSD's `kern_sigaction`). `raise` and `kill` accept every number from 1 to 128 now: a blocked one stays pending on the set of `sigtimedwait`, an unblocked one whose handler is registered runs it on the calling thread, and an unblocked one that has no host equivalent and no handler still fails with `EINVAL`, where FreeBSD runs its default action. `raise` of an `SA_SIGINFO` handler still throws instead of terminating
 - [kill, killpg](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) follow FreeBSD's `kern_kill` and `killpg1` for the only guest process: `EINVAL` for signals outside 0 to 128 and for negative `killpg` process groups, signal 0 only checks that the target exists, and its own pid, 0 and minus its own pid (the guest is taken to lead its own process group) signal it through `raise`, so they share `raise`'s limits above. Any other pid, and -1, which skips the caller, report `ESRCH`, so `EPERM` is never reported
 - [sceKernelFcntl](../../../core/libs/prx/libkernel/File/src/Open.cpp) (libkernel) runs the POSIX `fcntl` below and returns its guest errno as `SCE_KERNEL_ERROR_*`, the form the other `sceKernel` file exports use. The return values and error codes are unverified on a console
-- [fcntl](../../../core/libs/prx/libkernel/File/src/DescriptorControl.cpp) (libkernel) follows FreeBSD 11.4's [`kern_fcntl`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_descrip.c#L479-L799) and [`kern_dup`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_descrip.c#L812) on file, directory, pipe and character device descriptors; a socket keeps the libSceNet path (`F_GETFL`, `F_SETFL` with `O_NONBLOCK`, `F_GETFD` and `F_SETFD`, `EINVAL` for every other command, see the next entry). The close-on-exec flag and the status flags live in a guest table, the status flags shared by `dup`, `dup2` and `F_DUPFD` as in an open file description; a descriptor the table has not seen, such as 0 to 2, starts from the host's flags, since the console's are not known. `F_GETFL` takes the access mode from the host (the granted access of the handle on Windows), so pipe ends report `O_RDONLY` and `O_WRONLY` where FreeBSD's bidirectional pipes report `O_RDWR`. `F_DUPFD` and `F_DUPFD_CLOEXEC` return the lowest free host descriptor at or above the start, so the bound is the host table (`EMFILE` on Windows, `EINVAL` past `RLIMIT_NOFILE` on Linux), not the console's unknown `RLIMIT_NOFILE` and `kern.maxfilesperproc`. `O_NONBLOCK` switches a host pipe (`PIPE_NOWAIT` on Windows, where an empty read and a full write then report `EAGAIN`) and is only recorded on files, directories and the random device, as their reads never block; on a Windows console or other character device it throws. Changing `O_APPEND` on a Windows file, changing `O_FSYNC` on a file, `O_ASYNC` on a pipe or character device (`SIGIO` is not delivered), `F_GETOWN`, `F_SETOWN` and `F_SETLK_REMOTE` throw; `O_DIRECT`, `F_RDAHEAD` and `F_READAHEAD` are recorded as the hints they are. Record locks (`F_GETLK`, `F_SETLK`, `F_SETLKW` and their forms without `l_sysid`) use the host's POSIX locks on Linux, where `F_GETLK` with `F_UNLCK` throws. On Windows they follow [`kern_fcntl`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_descrip.c#L607-L752) and [`lf_advlockasync`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_lockf.c#L433-L487) for the one guest process, which owns every lock: `EOVERFLOW` for an `SEEK_CUR` start past `OFF_MAX`, then `EBADF` for `F_RDLCK` without read access or `F_WRLCK` without write access and `EINVAL` for another type, then `EINVAL` and `EOVERFLOW` for the range; as [`lf_blocks`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_lockf.c#L866) never lets locks of one owner conflict, whichever descriptor or thread asks, `F_SETLK` and `F_SETLKW` then succeed without waiting and `F_GETLK` reports `F_UNLCK`, so no lock list is kept and merging, splitting and the release on close have nothing to change. Nothing is held on the host, since Windows byte-range locks are mandatory and would fail the guest's own reads and writes through other descriptors, so other host processes neither see these locks nor are seen; a lock from the end of a directory throws. The return values and error codes are unverified on a console
+- [fcntl](../../../core/libs/prx/libkernel/File/src/DescriptorControl.cpp) (libkernel) follows FreeBSD 11.4's [`kern_fcntl`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_descrip.c#L479-L799) and [`kern_dup`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_descrip.c#L812) on file, directory, pipe and character device descriptors; a socket keeps the libSceNet path (`F_GETFL`, `F_SETFL` with `O_NONBLOCK`, `F_GETFD` and `F_SETFD`, `EINVAL` for every other command, see the next entry). The close-on-exec flag and the status flags live in a guest table, the status flags shared by `dup`, `dup2` and `F_DUPFD` as in an open file description; a descriptor the table has not seen, such as 0 to 2, starts from the host's flags, since the console's are not known. `F_GETFL` takes the access mode from the host (the granted access of the handle on Windows), so pipe ends report `O_RDONLY` and `O_WRONLY` where FreeBSD's bidirectional pipes report `O_RDWR`. `F_DUPFD` and `F_DUPFD_CLOEXEC` return the lowest free host descriptor at or above the start, so the bound is the host table (`EMFILE` on Windows, `EINVAL` past `RLIMIT_NOFILE` on Linux), not the console's unknown `RLIMIT_NOFILE` and `kern.maxfilesperproc`. `O_NONBLOCK` switches a host pipe (`PIPE_NOWAIT` on Windows, where an empty read and a full write then report `EAGAIN`) and is only recorded on files, directories and the random device, as their reads never block; on a Windows console or other character device it throws. Changing `O_APPEND` on a Windows file, changing `O_FSYNC` on a file, `O_ASYNC` on a pipe or character device (`SIGIO` is not delivered), `F_GETOWN`, `F_SETOWN` and `F_SETLK_REMOTE` throw; `O_DIRECT`, `F_RDAHEAD` and `F_READAHEAD` are recorded as the hints they are. Record locks (`F_GETLK`, `F_SETLK`, `F_SETLKW` and their forms without `l_sysid`) use the host's POSIX locks on Linux and macOS. `F_GETLK` with `F_UNLCK` asks the host with `F_RDLCK`: as in [`lf_blocks`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_lockf.c#L866) only another owner's overlapping write lock conflicts with either request. On Windows they follow [`kern_fcntl`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_descrip.c#L607-L752) and [`lf_advlockasync`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_lockf.c#L433-L487) for the one guest process, which owns every lock: `EOVERFLOW` for an `SEEK_CUR` start past `OFF_MAX`, then `EBADF` for `F_RDLCK` without read access or `F_WRLCK` without write access and `EINVAL` for another type, then `EINVAL` and `EOVERFLOW` for the range; as [`lf_blocks`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/kern_lockf.c#L866) never lets locks of one owner conflict, whichever descriptor or thread asks, `F_SETLK` and `F_SETLKW` then succeed without waiting and `F_GETLK` reports `F_UNLCK`, so no lock list is kept and merging, splitting and the release on close have nothing to change. Nothing is held on the host, since Windows byte-range locks are mandatory and would fail the guest's own reads and writes through other descriptors, so other host processes neither see these locks nor are seen; a lock from the end of a directory throws. The return values and error codes are unverified on a console
 - [fcntl on a guest socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) answers `F_GETFD`, `F_SETFD`, `F_GETFL` and `F_SETFL` and fails every other command with `EINVAL`; FreeBSD 11.4's `kern_fcntl` also duplicates the descriptor (`F_DUPFD`, `F_DUPFD_CLOEXEC`) and handles `F_GETOWN` and `F_SETOWN` on a socket. `FD_CLOEXEC` is only recorded (there is no `exec`): `dup`, `dup2` and an accepted socket start without it, `SOCK_CLOEXEC` and `F_SETFD` set it. None of this was measured on a console.
 - [ioctl, _ioctl](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) handle only `FIONBIO` and `FIONREAD` on a socket, and any other request there fails with `ENOTTY`. On the other descriptors they follow FreeBSD's [`kern_ioctl`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_generic.c#L758), [`vn_ioctl`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/vfs_vnops.c#L1488) and [`pipe_ioctl`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_pipe.c#L1346): `FIONBIO` sets `O_NONBLOCK` as `fcntl` does, `FIOCLEX` and `FIONCLEX` set and clear the close-on-exec flag `F_GETFD` reports, and `FIONREAD` reports the size past the offset of a file, the queued bytes of a pipe's read end, 0 on its write end and `ENOTTY` on the random device, while it throws on a directory or another character device. Every termios request (group `t`, `TIOCGWINSZ` included) fails with `ENOTTY`, since those descriptors are taken as not a terminal, as in `tcgetattr`, and any other request throws. Stremio Plus (PPSA74126) imports `_ioctl` for its statically linked `tc*` functions, which send `TIOCGETA`, `TIOCSETA`, `TIOCSPGRP` and the other termios requests
 - [Regular file mappings](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) - on Linux `mmap` maps a regular file's descriptor shared or private like a shared memory object, with the same access checks; SQLite's WAL index (`-shm`) in Dusklight PPSA99305 needs it. FreeBSD 11 `mmap(2)` and shadPS4's `MemoryManager::MapFile` map regular files; the console's behaviour is not measured. Other descriptors (pipes, sockets, directories, devices) still fail with `EOPNOTSUPP`, and Windows maps no files.

Subject: [PATCH 0686/1000] test(libkernel): check the timed locks against the
 holder's release, not elapsed time

The waiter took the lock only after the holder unlocked, but under load it
saw the holder's lock late and measured less than half the hold time.
The holder now sets a flag just before it unlocks and the waiter requires
it once its lock is taken.

Subject: [PATCH 0687/1000] test(libkernel): cover F_GETLK against another
 process's record locks

The fcntl tests only ever held locks in the guest's own process, where FreeBSD's lf_blocks never reports a conflict, so the host lock path that answers F_GETLK was not exercised. A forked process now holds a read lock, a write lock and a write lock to the end of the file through the host. F_GETLK with F_UNLCK reports only the write locks, F_RDLCK the same and F_WRLCK the read lock, each with the owner's pid and SEEK_SET; F_SETLK over the read lock fails with EAGAIN, and nothing is reported once the owner exits.

Structure layouts come from [shadPS4](https://github.com/shadps4-emu/shadPS4)'s `ngs2_reverb.h` and the param ids 0x20010000 (setup) and 0x20010001 (I3DL2) from PPSA22520. Only the default `reverb_size` of 1 is handled, with its 14400-sample reflection buffer; other sizes and the library's half-rate mode throw. System sample rates below about 7.5 kHz, where an allpass delay would have no samples, throw. Setup only accepts equal input and output channel counts

The signatures (report type, handler, user data, out handle) and (report handle) follow [SharpProspero](https://github.com/SvenGDK/SharpProspero) and [shadPS4](https://github.com/shadps4-emu/shadPS4)'s `ngs2_report.h`.

The other calls do not wait for the system lock. Peace Walker (PPSA18216) holds it while it spins on a flag that its audio thread clears only after `sceNgs2SystemRender` and eight `sceNgs2VoiceGetStateFlags` calls, so on the console neither can wait for it. Whether the console's voice and rack calls take the lock at all is not known. `sceNgs2RackLock` still holds the library's lock until `sceNgs2RackUnlock`, as before

The last process ratio and tick and `active_channel_work_count` are left zero
 - [sceNgs2VoiceQueryInfo](../../../core/libs/prx/libSceNgs2.native/src/Voice.cpp) (libSceNgs2.native) - only info id 0x4001 is known: PPSA22520 passes an 8-byte buffer and branches on the first word being 1 or 2, so it is assumed to be the voice channel count (0 before the voice is set up); the second word is zeroed and other ids throw
 - [sceNgs2VoiceControl patch](../../../core/libs/prx/libSceNgs2.native/src/Voice.cpp) (libSceNgs2.native) - a destination rack handle with input id 0 resolves to that rack's first voice; this matches the Dead Cells call in #4334, but selection for racks with multiple voices has not been checked against a console. Nonzero destination input ids still throw. `sceNgs2VoiceGetPortInfo` reports the resolved voice handle and zero delay.

Subject: [PATCH 0689/1000] fix(libkernel): report free send space for socket
 write events on Linux

A socket's EVFILT_WRITE and sceKernelAddWriteEvent reported the whole SO_SNDBUF in data, however much was already queued. FreeBSD 11.4's filt_sowrite reports sbspace, the space still free. On Linux the queued bytes from SIOCOUTQ are now taken off SO_SNDBUF. Windows has no query for the queued bytes and macOS is not wired up, so both keep reporting SO_SNDBUF; the debt entry says so.

Invalid values return `EINVAL` without changing the attribute. Guest threads execute in one host process; sharing mutexes across processes is not modeled. Console behavior and invalid-attribute error precedence are unverified.

A null output of `pthread_attr_getinheritsched` throws, since libthr writes through it unchecked. A thread keeps the scope it was created with, taken from the creating thread under `PTHREAD_INHERIT_SCHED`, and `pthread_attr_get_np` and `scePthreadAttrGet` report it, but every guest thread is a host thread at system scope, so process scope changes nothing
 - [Shared memory](../../../core/libs/prx/libkernel/File/src/SharedMemory.cpp) (libkernel) on Linux implements anonymous and named objects, bounded descriptor writes and seeks, and `shm_unlink` with effective read/write permission checks from FreeBSD 11. Named paths up to 1023 bytes use `/anyps5-shm-` plus SHA-1; collisions are not detected, and the namespace is shared across processes in the host mount namespace. Named creation applies the guest umask without changing the host mask. Linux procfs and `/dev/shm` are required. Operations use an advisory directory lock; external host operations bypass it, unrelated objects serialize, and descriptor operations require two spare host descriptors and compare device/inode with the initial descriptor identity on both the pinned-object and ordinary-file fallback paths. [Guest mappings](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) support shared and private mappings of these descriptors through the allocation tracker and pin a duplicate descriptor during validation and mapping; mapping requires one spare host descriptor; file-backed mappings use the write-watch scan fallback because aliases and descriptor writes bypass per-mapping tracking. Named objects and file-backed mappings on Windows remain unsupported. Invalid non-null name pointers, console behaviour and title compatibility remain unverified.
-- [sceKernelAddReadEvent and sceKernelAddWriteEvent](../../../core/libs/prx/libkernel/Equeue/Equeue.cpp) (libkernel): a write event reports the socket's send buffer size (`SO_SNDBUF`) in `data`, not the free space left in it, as Windows has no query for that space.

+- [sceKernelAddReadEvent and sceKernelAddWriteEvent](../../../core/libs/prx/libkernel/Equeue/Equeue.cpp) (libkernel): a write event reports the free space of the socket's send buffer in `data`, as FreeBSD 11.4's [`filt_sowrite`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c#L3358-L3382) reports `sbspace`: on Linux the host's `SO_SNDBUF` less the bytes `SIOCOUTQ` counts as queued, which include the host's per-packet overhead, so the space shrinks by somewhat more than the bytes sent. Windows has no query for that space and macOS is not wired up, so both report the whole `SO_SNDBUF`, which does not shrink as data is queued. Only guest sockets are supported; other descriptors and a low watermark above 1 throw
 - [close](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) and [setsockopt](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) reach a [libSceNet](../../../core/libs/prx/libSceNet/Export.cpp) socket through hooks libSceNet registers, as `select` polls them; the other libkernel socket calls do not. libSceNet numbers its sockets from 32 in its own table, so a CRT file descriptor and a socket can share a number; `close` then closes the socket. On the console both are one kernel descriptor space
 - [sceKernelPread, sceKernelPwrite, sceKernelPreadv, sceKernelPwritev](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on Windows transfer at the given offset with an overlapped `ReadFile`/`WriteFile` and restore the descriptor's file pointer afterwards. Guest scalar transfers, positioned transfers, vectored transfers and seeks share a position lock across duplicated descriptors; a vector holds it for the whole operation. Independently opened descriptors and other processes do not share that lock, so vector transfers over their overlapping file ranges are not coordinated. Handles that are not disk files return `ESPIPE`. A pipe or console `readv` can return a short read when no more input is available; each iovec is transferred separately, so a failure after the first transfer returns the bytes already done
 - [sceKernelAioSubmitReadCommands, sceKernelAioSubmitWriteCommands and their Multiple variants](../../../core/libs/prx/libkernel/Aio/src/Aio.cpp) (libkernel) on Windows transfer through the same positioned path as `sceKernelPread`/`sceKernelPwrite` and restore the descriptor's file pointer afterwards; positioned transfers, plain transfers and seeks of one descriptor are serialized per descriptor (shared across duplicated descriptors), so a concurrent transfer observes a stable file pointer

Subject: [PATCH 0690/1000] test(libkernel): check socket write event space
 shrinks and recovers

On a Unix stream socketpair the write event's data drops by at least the bytes sent while the peer has not read them, and comes back to the idle value once the peer drains them. Off Linux the test only checks that the value stays positive and never grows.

Subject: [PATCH 0691/1000] fix(agc): let the storage image cache budget follow
 the heap's use like the sampled one

StorageTextureBudget gave the storage image cache a quarter of the VK_EXT_memory_budget
budget of the largest device-local heap (capped at TextureCacheBudget, never below 512 MiB)
whatever else the heap held, while SampledTextureBudget takes what that budget leaves after
the heap's other use. On a 10 GB card the storage cache kept 2024-2170 MiB into a level load
whose depth and render target allocations then failed with VK_ERROR_OUT_OF_DEVICE_MEMORY
with the heap at its reported budget where a run logged it.

The storage image budget is now what the reported budget leaves after the heap's use other
than the cached storage images, the unused part of the sampled textures' 2 GiB floor and an
eighth of the budget; the caps at a quarter of the budget and at TextureCacheBudget and the
512 MiB floor stay. The sampled budget still reserves TextureCacheBudget for the storage
cache, at least the storage cap, and the storage budget reserves the sampled textures alive,
so neither counts bytes the other may take; while the sampled textures alive stay within
their floor the sampled budget falls first, then the storage budget, and above it both fall
together. The budget line also prints when the storage image budget moves by more than a
tenth, with its previous value, and StorageTextureCacheBudget is exported for the execution
test.

 ### Functional
 
+- [Texture cache budgets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - the storage image cache's budget is what the reported heap budget leaves after the heap's use other than the cached storage images, the unused part of the sampled textures' 2 GiB floor and an eighth of the budget, capped at a quarter of the budget and at `TextureCacheBudget` (a quarter of the heap's size, at least 2 GiB), never below 512 MiB; the sampled cache's budget reserves `TextureCacheBudget` for the storage cache. So the sampled budget falls first while the sampled textures alive stay within their floor, and both fall together above it; each cache trims only at its next insert, a storage image is allocated before its insert reads the budget, and both budgets read the heap at most once a second, so a burst between two reads can still exceed the reported budget. The 2 GiB floor and the eighth are the sampled formula's values reused and the 512 MiB floor and the caps the earlier ones; none was measured beyond one title (PPSA11386) on one 10 GB GPU, and a title whose storage working set exceeds the shrunk budget re-creates storage images at each use.
 - [Native multisampled DCC fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) import uniform 0000/0001/1110/1111 keys into a single-layer, level-zero SW_64KB_R_X color image with 2, 4 or 8 fragments. Color and DCC/CMASK ranges must stay write-watched and unchanged; expanded or mixed initial DCC, register CMASK clears, compressed payloads, color transforms, lossy modes, metadata changes, guest publication and writes over a live owner throw. Driver-mediated reads of the color and metadata stay guarded. The metadata extent follows [AMD Addrlib](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp#L347-L454) with the [PS5 Mesa model](https://github.com/mihawk-99/PS5_Mesa/blob/0b2d6d1a61d9bbf89cf8beb88a696144f67c61f8/src/amd/vulkan/winsys/ps5/radv_ps5_winsys.c): GFX10.1, 16 pipes, 256-byte interleave, two maximum compressed fragments. Console geometry, concurrent guest mutation and transitions outside this subset are unverified.
 
 - [Initial stencil state](../../../core/libs/prx/libSceAgcDriver/Execution/include/QueueState.hpp) uses zero for `DB_STENCIL_CONTROL`, `DB_STENCILREFMASK` and `DB_STENCILREFMASK_BF` (context `0x10b`-`0x10d`), including after `CLEAR_STATE`. The public V0, V4, V5 and V7-V11 [register-default tables](../../../core/libs/prx/libSceAgc/Command/include/RegisterDefaultsData.hpp) supply these values. Linux's [GFX10 clear-state table](https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/amd/amdgpu/clearstate_gfx10.h) agrees on the control register but uses `0x01000000` for the reference masks; the console reset values have not been measured. Planet Coaster (PPSA01736 v01.017) enables stencil tests without writing the control register.

 ### Texture cache budget
 
-Sampled textures and storage images stay in device memory in two caches that evict their least recently used entries when they grow past their budgets. The storage image budget is a quarter of the `VK_EXT_memory_budget` budget of the largest device-local heap, capped at a quarter of the heap's size or 2 GiB, whichever is larger, and never below 512 MiB. The sampled texture budget is what the reported budget leaves after the heap's use other than cached textures, that cap and an eighth of the budget, and never below 2 GiB. Both are read again every second; `[gpu] sampled texture cache budget` lines report them at start-up and when they change. `APS5_TEXTURE_CACHE_MIB=<n>` fixes both budgets at `n` MiB, and the lines are then not printed.
+Sampled textures and storage images stay in device memory in two caches that evict their least recently used entries when they grow past their budgets. The storage image budget is what the `VK_EXT_memory_budget` budget of the largest device-local heap leaves after the heap's use other than the cached storage images themselves, the part of the sampled textures' 2 GiB floor not yet in use, and an eighth of the budget; it is capped at a quarter of that budget, at most a quarter of the heap's size or 2 GiB, whichever is larger, and never below 512 MiB. The sampled texture budget is what the reported budget leaves after the heap's use other than cached textures, a quarter of the heap's size (at least 2 GiB) and an eighth of the budget, and never below 2 GiB. While the sampled textures alive stay within their floor the sampled budget falls first, to that floor, then the storage budget; above it both fall together. Each cache trims at its next insert. Both budgets are read again every second; `[gpu] sampled texture cache budget` lines report them at start-up and when either moves by more than a tenth, at most every 10 s. `APS5_TEXTURE_CACHE_MIB=<n>` fixes both budgets at `n` MiB, and the lines are then not printed.
 
-A fixed budget above the automatic one can exceed what the card holds next to the rest of the frame. Allocations then go to host memory (`[gpu] ... placed in host memory` lines), where the GPU reads them over PCIe. PPSA16064 on an RTX 4060 8 GB, whose automatic storage image budget is 1797 MiB, placed 868 and 878 MiB in host memory with `APS5_TEXTURE_CACHE_MIB=3072` and walked through its first level at 4.46 and 4.83 FPS; with the variable unset it placed none and ran the same walk at 6.48 and 6.07 FPS. Leave it unset unless a measurement on the card shows otherwise.

 - [Flip packets raise the graphics end-of-pipe event](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Packets/PacketExecution.cpp) (libSceAgcDriver) - a flip delivers the queue's end-of-pipe event (`sceAgcDriverAddEqEvent`) once the work recorded before it completes, as a `RELEASE_MEM` with `INT_SEL` does. Minecraft (PPSA17221) registers the graphics event, never requests an interrupt in its releases, and waits on the event after every flip while holding its render lock, so without this it never presents a second frame. Whether the console raises the event from the flip itself or from an interrupt its flip sequence contains is not measured; a title that waits only on release interrupts sees one extra event per flip, with `data` counting it.
 - [Host import windows and budget](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): a registered range larger than 64 MiB is imported one 64 MiB window at a time for buffer and fill accesses; an access across window edges imports the cells it touches, grown to the union of the range's imports it overlaps. An address-based build (`AcquireRegistered`) imports the range whole and replaces its windows. Live imports stay under a budget: `APS5_HOST_IMPORT_MIB`, else the larger of 6 GiB and half the physical memory, at most the largest host heap less 2 GiB (imports and type-3 mirrors share it; #167's rule). A new import beyond it retires the least recently used imports not used in the last 256 lookups; one that would not fit even then is refused before anything is retired, and imports made when a range is mapped never evict. A refused import is tried again at its next use. The 64 MiB window, the 256-lookup protection and the 2 GiB reserve are choices, not measured.
 - [Registration preparation at submit](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Queues/Submission.cpp) (libSceAgcDriver) - `Driver::Submit` waits for every registration-time shader preparation queued before the call, not only those of the shaders the commands use, so a submission behind a long queue of unrelated preparations waits for all of them on the submitting thread. Waiting there instead of in the queue worker keeps the GPU side of a submission short: a title that sees a submission take seconds treats the GPU as hung (Goat Simulator 3, PPSA04159, then stops submitting and its garbage collector fails a 10 s timeout). On the console shaders are compiled ahead of time, so neither wait exists; how long a title tolerates a slow submit call is not known.
+- [Unclamped normalized color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - CB_COLOR_INFO targets with BLEND_CLAMP clear (bit 15) on UNORM and SNORM formats are accepted when blending is disabled (ENABLE clear or BLEND_BYPASS set). Vulkan converts unblended shader values and clamps to the normalized range automatically; blending into an unclamped normalized target remains unmodeled because Vulkan always clamps inputs prior to blending.

Subject: [PATCH 0693/1000] fix(libSceSystemService): park guest threads during
 LoadExec's shutdown as exit does

Metal Gear Solid 4 (PPSA18194) aborts on main when its launcher starts
the game: sceSystemServiceLoadExec runs the guest shutdown, a render
thread that then calls into the stopped AGC driver gets ProcessShutdown
back from LibcAwaitExit, and the exception unwinds into title code,
which terminates the process before the new executable starts.

LibcAwaitExit parks a thread only once an exit has been requested, and
LoadExec ran the shutdown without requesting one. It now starts the
shutdown the way exit does, so such threads wait until the process is
replaced.

Windows starts a suspended process that inherits only the standard streams and a handle of the old process, and its entry stub waits for the old process to end before it loads the title's libraries, so a shell or script that started the title sees it end. A null list or one without a first entry keeps the earlier launch: the new executable gets only its own path as its command line (`CreateProcessW` on Windows, `execv` on Linux), so its `argv[0]` is the host path, and the old process ends without waiting for it. What the console passes for such a list is not known, nor are its argument limits and error codes. Paths outside `/app0`, unconverted executables and macOS hosts throw
 - [Running application ID](../../../core/libs/prx/libSceSystemService/Export.cpp) (libSceSystemService) - `sceSystemServiceGetAppIdOfRunningBigApp` reports 1 as the running title's app ID. The value is AnyPS5's own: the console's shell assigns app IDs and their values are not known here, so other calls that take an app ID must use the same one. `sceSystemServiceKillApp` with that ID and the arguments -1, 0 and 0, which [SwanStationPS5](https://github.com/darkxex/SwanStationPS5/blob/4cdc981d1a64ffb7f2af73f7a27a9e91a3cb5eb4/src/main.c#L1050-L1058) passes to close itself and [ps5-payload-dev's hbldr](https://github.com/ps5-payload-dev/websrv/blob/46374edee6627885abac717de24da7a1d73af6f1/src/ps5/hbldr.c#L425-L435) passes to close the running game, ends the title as its own `exit(0)` would: the guest's shutdown and `atexit` handlers run and the process exits with status 0. On the console the call returns and the shell then ends the title, and whether those handlers run there is unknown; here there is no shell, so the call does not return. Another app ID or other arguments throw.
 - [LoadExec descriptors](../../../core/libs/prx/libSceSystemService/LoadExec.cpp) (libSceSystemService) - on Linux, a call with an argument list replaces the process with `fexecve`, which first closes every descriptor above 2; a call without one uses `execv`, and the guest's descriptors stay open across it. On both paths descriptor 2 first gets back the host standard error a guest redirect kept, so the runtime's output does not follow the title's redirect (RetroArch's trace file, VLC's log) into the next executable. Which descriptors the console passes to the new process is not known

Subject: [PATCH 0694/1000] fix(libSceSystemService): run the shutdown
 callbacks after LoadExec starts the exit

Since #5978, StartExit only parks the other guest threads and exit runs
LibcRunShutdown itself, so LoadExec's three exits (the converted
executable on Windows and Linux, and the host executable) now call
LibcStartExit and then LibcRunShutdown, as exit does.

Subject: [PATCH 0695/1000] fix(libkernel): take NOTE_LOWAT on socket read and
 write events

kevent threw for NOTE_LOWAT. On a socket's EVFILT_READ it now sets the
low-water mark as FreeBSD 11's filt_soread does: the event fires once the
buffered bytes reach it, or at end of file or on a listening socket, and
a later change of the knote replaces it. EVFILT_WRITE takes a mark of 1,
where the host's writability stands in for a free byte; other write marks
and marks below 1 still throw. A pipe ignores the mark, as filt_piperead
does.

 - [sceKernelMprotect, sceKernelMtypeprotect](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) (libkernel) over a range with a gap that is not registered in the allocation tracker protect the registered parts and skip the gap, and return 0, as FreeBSD 11.4's [`vm_map_protect`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/vm/vm_map.c) does (it has no check for holes); a range whose start is unmapped (also when later pages are mapped) returns `SCE_KERNEL_ERROR_EINVAL` (`mprotect`: `EINVAL`) because an existing test pins that for an unmapped start; FreeBSD answers 0 there too (`vm_map_protect` takes the next entry), so this errno is not taken from the source and was not changed. `sceKernelMprotect` threw for a gap before, which ended the title. Every part is checked for a GPU or image pin before the first one is protected; the parts are then protected one after the other, so a host protection failure in a later part leaves the earlier parts changed (FreeBSD's `vm_map_protect` cannot fail in its second pass). The behaviour on the console is not known. None of this was measured on a console.
 - [sceKernelMprotect protection bits](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) (libkernel) - bits outside `0x3F7` are dropped instead of refused, as FreeBSD 11's [`sys_mprotect`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/vm/vm_mmap.c#L606) does with `VM_PROT_ALL`. Onimusha: Way of the Sword (PPSA27836 01.000.001) maps direct memory with `0xf2` and then protects it with `0xfffffff2`. Not measured on a console; the map calls and `sceKernelMtypeprotect` still refuse undefined bits
 - [JIT shared memory](../../../core/libs/prx/libkernel/DirectMemory/Jit.cpp) (libkernel) - `sceKernelJitCreateSharedMemory`, `sceKernelJitCreateAliasOfSharedMemory` and `sceKernelJitMapSharedMemory` take the signatures of [Orbital](https://github.com/AlexAltea/orbital)'s `tools/ida/db_types.json` (name, length, maximum protection, descriptor out; descriptor, maximum protection, descriptor out; descriptor, protection, address in and out), which ps4sdk, ps5-jar-loader and the call sites in RetroArch PPSA99169, XPSemu PPSA97358 and VLC PPSA85300 match; SharpProspero declares the alias as returning the descriptor. The object is a host anonymous file shared by its descriptors (a `memfd` on Linux, a delete-on-close temporary file mapped as an executable section on Windows), the alias is a duplicate descriptor, and every map maps the whole object, so writes through one view show through the others; a non-null address is a hint, as in `mmap` without `MAP_FIXED`. Not measured on the console: a length that is zero or not a multiple of 16 KiB and protection bits other than CPU read, write and execute are `EINVAL`; an alias or a map asking for more than the descriptor's maximum protection (write and execute counting as read) is `EACCES`, as FreeBSD 11's `vm_map_protect` treats a protection past `max_protection`; a descriptor that is not a JIT object is `EBADF`. The name is ignored, the objects do not count against the flexible memory budget, `mprotect` of a view is not limited to the maximum protection, and `mmap` of the descriptors is unsupported, as for `shm_open`. On Linux the `memfd` is created without `MFD_EXEC`, which Linux 6.3 added and older kernels reject with `EINVAL`, and relies on the protection of the mapping: the flag only sets the file's execute permission bits, and the direct memory `memfd` is mapped executable the same way; a host with `vm.memfd_noexec` set to 2 refuses the creation and the call throws
-- [kqueue and kevent](../../../core/libs/prx/libkernel/Equeue/src/Kqueue.cpp) (libkernel) follow FreeBSD 11's [`kern_event.c`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/kern_event.c) (`kqueue_kevent`, `kqueue_register`, `kqueue_scan`, the timer and user filters) over the event queue; nothing is measured on a console.

A write event takes a mark of 1 only, where the host's writability stands in for one free byte, since the host does not report the send buffer's free space; other write marks and marks below 1, which make FreeBSD's read filter always fire, throw
 - [EVFILT_VNODE, sceKernelAddFileEvent and sceKernelDeleteFileEvent](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) (libkernel) watch the host file or directory behind the descriptor and turn host changes into FreeBSD 11 vnode hints, which [`filt_vfsvnode`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L5032) adds whole when they share a bit with the requested `fflags`: a write that grows a file is `NOTE_WRITE | NOTE_EXTEND`, another write `NOTE_WRITE`, a shrinking truncate or an attribute change `NOTE_ATTRIB`, a higher link count `NOTE_LINK`, a lower one or a pending delete `NOTE_DELETE`, a new path `NOTE_RENAME`; in a directory, an entry created, removed or renamed is `NOTE_WRITE`, with `NOTE_LINK` for a subdirectory, and on Linux an entry moved from or to another directory adds `NOTE_EXTEND`; inotify queues the two halves of a rename one after the other, so a watcher woken by the first can read it alone, and a half read without the other is classified only after a `getdents64` on the watched directory, which takes the directory lock that `rename` holds until both halves are queued ([`do_renameat2`](https://github.com/torvalds/linux/blob/v6.8/fs/namei.c#L4975) around `vfs_rename` and its `fsnotify_move`, [`iterate_dir`](https://github.com/torvalds/linux/blob/v6.8/fs/readdir.c#L103)), an ordering taken from the kernel source, not from inotify(7), which promises none; a directory registered with `NOTE_EXTEND` on Windows is accepted, as `vfs_kqfilter` does not check it, but never receives it, because the directory handle cannot tell a move between directories from a removal plus an addition. FreeBSD's hints depend on the filesystem and the console's filesystems are not known: a growing `ftruncate` reports `NOTE_WRITE | NOTE_EXTEND` where `vop_setattr_post` reports `NOTE_ATTRIB`, and on Windows `utimes` on a file reports `NOTE_WRITE`. The three Windows notifications are told apart in the error, which names the `parent`, `entries` or `subdirectories` watch, the path it was given and `GetLastError`, but a `FindFirstChangeNotification` that fails still throws rather than returning an error to the guest: the EVFILT_VNODE attach path is [`vfs_kqfilter`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L4936), which returns `EINVAL`, `ENOMEM` or 0 after `fget` has turned a descriptor that is not open into `EBADF`, and consults no directory permission, so no FreeBSD errno stands for a host that refuses to notify, and what the console does on such a host is not measured. Only the `parent` watch can fail this way in practice: `entries` and `subdirectories` need the `FILE_LIST_DIRECTORY` that opening the watched directory already took. The parent handle produces no hint of its own, as `RunHostWatch` only calls `FindNextChangeNotification` on it, so a later change may leave the watch on its 50 ms poll instead of throwing; that is not done here. Windows uses `FindFirstChangeNotification` on the parent directory (and on a watched directory itself) and compares `GetFileInformationByHandleEx` snapshots at least every 50 ms, because a write through an open handle is reported only when the handle is flushed or closed, so file hints can arrive 50 ms late, and a file deleted while watched, which the POSIX delete of Windows 10 1903 moves into `$Extend\$Deleted` until its last handle closes, reports `NOTE_DELETE` without `NOTE_RENAME` and keeps its handle without a parent directory watch, as that directory cannot be watched; Linux uses inotify on the file and is not run. `NOTE_REVOKE`, `NOTE_OPEN`, `NOTE_CLOSE`, `NOTE_CLOSE_WRITE`, `NOTE_READ`, unknown bits and descriptors other than files, directories, pipes and sockets throw. `sceKernelAddFileEvent(eq, fd, watch, udata)` and `sceKernelDeleteFileEvent(eq, fd)` take the [OpenOrbis](https://github.com/OpenOrbis/OpenOrbis-PS4-Toolchain/blob/0a1aaf9d/include/orbis/libkernel.h#L35) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0/src/SharpProspero/Interop/Kernel/KernelEqueue.cs#L164) signatures; `watch` is taken as the `fflags` and the event is added with `EV_CLEAR`, neither confirmed on a title (feat(libkernel): implement kevent EV_DISABLE, EV_DISPATCH and EV_FORCEONESHOT) (fix(libkernel): follow kqueue_register for EV_FORCEONESHOT and modify flags)
 - [sem_timedwait](../../../core/libs/prx/libkernel/Pthread/Posix/Sem.cpp) (libkernel) consumes an available count before checking the timeout and waits indefinitely for a null timeout, following FreeBSD 11's `sem_timedwait`. Console behavior for null and invalid timeouts when a count is available is unverified.

FreeBSD's `pipe_ioctl` answers `TIOCGPGRP` and `TIOCSPGRP` on a pipe or FIFO with the descriptor's SIGIO owner, which is not modelled, so `tcgetpgrp` and `tcsetpgrp` throw on a host pipe or FIFO above descriptor 2; descriptors 0 to 2 are taken as non-terminals that are not pipes, whatever the host attaches to them, so a pipe the guest creates on a freed descriptor 0 to 2 gets `ENOTTY` there. The PS5 `libkernel` is assumed to use this FreeBSD code, and `tcdrain` is not a cancellation point here

 - [Socket descriptor numbers](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel, libSceNet) - `socket`, `accept`, `socketpair`, `dup`, `sceNetSocket` and `sceNetAccept` take the lowest free number of the host descriptor table that files use, as FreeBSD 11.4 `fdalloc` takes the lowest free entry of the one process table (`kern_descrip.c`), so every number stays below `FD_SETSIZE` (1024) while fewer than 1024 descriptors are open. The number holds a zero-access `NUL` handle on Windows and a duplicate of the host socket on Linux, and the socket tables map it to the socket. The host table also holds the runtime's own files, so the numbers differ from the console's; the first number `socket` and `sceNetSocket` return on a console and its `getdtablesize` are not measured. Paths that bypass the socket tables see the placeholder: libc `fdopen` on a socket opens it, and libkernel `close` of a libSceNet socket releases the number but leaves the libSceNet socket open. Palworld (PPSA23126), The Mound (PPSA26223) and Dying Light 2 (PPSA02262) set socket bits in a 1024-bit `fd_set`

Only this process's shutdown closes a side here; a peer's shutdown, close or reset does not clear the bits as FreeBSD's socantrcvmore and socantsendmore do. st_size is the host's FIONREAD, which for a Linux datagram socket is the size of the next datagram where FreeBSD counts every queued byte, and st_blksize is the host's SO_SNDBUF, which Linux reports as twice the size that was set. A socketpair end reports st_dev and st_ino 0, where FreeBSD's uipc_sense reports NODEV and a per-socket number
 - [poll](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) waits on guest sockets and pipes, through `WSAPoll` on Windows and `poll` on Linux; the `pollfd` layout and flag values are FreeBSD's. A libSceNet socket joins the same host wait through the native socket libSceNet lends to libkernel. `WSAPoll` rejects `POLLPRI`, so on Windows a socket's `POLLPRI` is asked as `POLLRDBAND` and `POLLIN` as `POLLRDNORM`; Winsock reports urgent data until it is read with `MSG_OOB`, where FreeBSD 11.4's `sopoll_generic` stops once the normal stream passes the mark. Guest `send` and `recv` refuse `MSG_OOB` with `EOPNOTSUPP`, so urgent data can only come from an outside peer and Windows keeps reporting `POLLPRI` after the stream passes the mark. A pipe follows FreeBSD's `pipe_poll`: the read end is readable when data is buffered, either end reports `POLLHUP` once the other end is closed, with the requested `POLLIN` and `POLLRDNORM` bits and without `POLLOUT`, which `pollscan` clears, and the write end is writable when `PIPE_BUF` (512) bytes are free on Windows, or when the host kernel says so on Linux. `POLLOUT` on a read end throws: FreeBSD opens both ends for reading and writing and reports it writable, and host pipes are one-way. Windows pipes cannot be waited on, so while a pipe is polled `poll` checks it with `NtQueryInformationFile` and waits on the sockets in slices of 1 ms. A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket nor a pipe (files, stdio) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on. A closed socket descriptor reports `POLLNVAL`; the console's limit on the descriptor count is unknown and not checked

Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`.

A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.

On Linux a socket bound to an explicit port keeps its local address as well (`127.0.0.1:<port>` stays `127.0.0.1:<port>`), because a bound socket cannot be bound again; one bound to port 0 is bound again to the wildcard address with the port it had

With MBEDTLS_SELF_TEST, ecp.c counts point additions, doublings and
field multiplications in unsynchronized globals. Handshakes on separate
connections run in parallel, each under its own session lock, so the
counters race; ThreadSanitizer reports it on the parallel transport
test. Nothing calls the self-test functions.

Subject: [PATCH 0697/1000] fix(agc): count every physical pointer write form
 in the BDA store scan

The scan listed stores, memory copies and atomics, and took only typed
OpTypePointer declarations as physical pointer types. A module that
wrote guest memory through an untyped PhysicalStorageBuffer pointer
(SPV_KHR_untyped_pointers), through a GLSL.std.450 Modf or Frexp output
pointer, or with a cooperative matrix store would have been taken for
one that only reads through the BDA table, and its draws would have
continued a render pass they must end. The recompiler emits none of
these today, so no module's answer changes.

Untyped physical pointer types now count as physical pointer types, an
extended instruction with a physical pointer operand counts as a store,
and the cooperative matrix stores store through their pointer operand.
Pointer type declarations no longer add their storage class to the
pointer values.

The tests build modules for every write form the scan knows, the reads
it must not take for writes, and the three forms above.

Subject: [PATCH 0698/1000] test(agc): order draws reading through the BDA
 table against buffer descriptor stores

A draw that only reads through the table now leaves its pass open to
the next draw, so its ordering against guest memory written through a
buffer descriptor rests on the pass hazard tracker's unknown-read rule
alone. Two cases cover it in agc_driver_address_passes: a draw that
reads through the table what the previous draw stored through a buffer
descriptor begins its own pass and sees the store, and a draw storing
through a buffer descriptor after one that read through the table
begins its own pass. Both fail when the tracker drops that rule.

Subject: [PATCH 0699/1000] test(agc): accept any NaN where the f16 fma and
 fma_mix tests expect one

agc_driver_f16_fma_denormal_modes and
agc_driver_fma_mix_f16_denormal_modes compared NaN results (inf * 0)
bit for bit with the RX 6700 XT's, but the NaN bits of f16 arithmetic
and of v_fma_mix_f32 with f16 sources are left to the driver, so the
tests fail on NVIDIA (0x7fff for 0xfe00). Rows whose expected value is
a NaN now accept any NaN; every other row is still exact.

Subject: [PATCH 0700/1000] feat(libSceNpTrophy2): declare
 sceNpTrophy2GetRewardIcon's arguments

The bundled PSNCore.prx of PPSA06888 calls sceNpTrophy2GetRewardIcon
with (context, handle, reward_id, buffer, size): once with a null buffer
to read the size, then with a buffer of that size. The function still
throws because the reward icon data is unknown.

Subject: [PATCH 0701/1000] ci: run the relinker TLS coverage tests under
 AddressSanitizer

The segment-prefix-at-eof case from #6401 only catches the 1-byte read
past the input when the relinker is built with AddressSanitizer, and no
CI job did that. The new job builds the relinker alone in Debug with
ANYPS5_ENABLE_ASAN and runs the tls_function_coverage tests. It has to
be Debug: at -O3 GCC no longer emits the stray load, so a Release ASan
build passes with the fix reverted.

Subject: [PATCH 0703/1000] fix(libkernel): keep refusing a read low-water mark
 above 1 on non-stream sockets

On Linux, FIONREAD on a datagram socket reports the next datagram only,
where FreeBSD's sbavail counts every queued byte, so a read mark above 1
there could never fire. kevent now throws for it as before; stream
sockets and marks of 1 are unchanged.

Every part is checked for a GPU or image pin before the first one is protected; the parts are then protected one after the other, so a host protection failure in a later part leaves the earlier parts changed (FreeBSD's `vm_map_protect` cannot fail in its second pass). The behaviour on the console is not known. None of this was measured on a console.
 - [sceKernelMprotect protection bits](../../../core/libs/prx/libkernel/DirectMemory/Export.cpp) (libkernel) - bits outside `0x3F7` are dropped instead of refused, as FreeBSD 11's [`sys_mprotect`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/vm/vm_mmap.c#L606) does with `VM_PROT_ALL`. Onimusha: Way of the Sword (PPSA27836 01.000.001) maps direct memory with `0xf2` and then protects it with `0xfffffff2`. Not measured on a console; the map calls and `sceKernelMtypeprotect` still refuse undefined bits
 - [JIT shared memory](../../../core/libs/prx/libkernel/DirectMemory/Jit.cpp) (libkernel) - `sceKernelJitCreateSharedMemory`, `sceKernelJitCreateAliasOfSharedMemory` and `sceKernelJitMapSharedMemory` take the signatures of [Orbital](https://github.com/AlexAltea/orbital)'s `tools/ida/db_types.json` (name, length, maximum protection, descriptor out; descriptor, maximum protection, descriptor out; descriptor, protection, address in and out), which ps4sdk, ps5-jar-loader and the call sites in RetroArch PPSA99169, XPSemu PPSA97358 and VLC PPSA85300 match; SharpProspero declares the alias as returning the descriptor. The object is a host anonymous file shared by its descriptors (a `memfd` on Linux, a delete-on-close temporary file mapped as an executable section on Windows), the alias is a duplicate descriptor, and every map maps the whole object, so writes through one view show through the others; a non-null address is a hint, as in `mmap` without `MAP_FIXED`. Not measured on the console: a length that is zero or not a multiple of 16 KiB and protection bits other than CPU read, write and execute are `EINVAL`; an alias or a map asking for more than the descriptor's maximum protection (write and execute counting as read) is `EACCES`, as FreeBSD 11's `vm_map_protect` treats a protection past `max_protection`; a descriptor that is not a JIT object is `EBADF`. The name is ignored, the objects do not count against the flexible memory budget, `mprotect` of a view is not limited to the maximum protection, and `mmap` of the descriptors is unsupported, as for `shm_open`. On Linux the `memfd` is created without `MFD_EXEC`, which Linux 6.3 added and older kernels reject with `EINVAL`, and relies on the protection of the mapping: the flag only sets the file's execute permission bits, and the direct memory `memfd` is mapped executable the same way; a host with `vm.memfd_noexec` set to 2 refuses the creation and the call throws

The descriptor is a host null device registered as the kqueue: `close` and `sceKernelClose` close the queue and `dup`/`dup2` of it throw, but `read`, `write` and `fstat` act on the null device instead of failing with `EOPNOTSUPP` or reporting `S_IFIFO`. Read and write events are supported on guest sockets only, plus `EVFILT_READ` on the read end of a pipe (see the kevent on a pipe entry) and the timer, user and [vnode](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) filters; other filters, `EV_CLEAR` on a socket or a pipe, `EVFILT_READ` on another kqueue, a `NOTE_NSECONDS` period above one second with a fraction (11.0 converts the fraction with the microsecond macro) and any change to an existing timer (11.0 keeps the armed expiry and applies the new period after it, 11.4's `filt_timertouch` restarts it) throw. `EV_DISABLE`, `EV_DISPATCH` and `EV_FORCEONESHOT` follow kern_event.c: a disabled knote stays registered, stops polling or firing and is not reported, a trigger raised while it is disabled is kept and reported after `EV_ENABLE`, where `knote` would drop it, `EV_DISPATCH` reports once and then disables the knote, and `EV_FORCEONESHOT` is ignored on a new knote while on an existing one it sets `EV_ONESHOT` and fires the knote; a negative `nevents` fails with `EINVAL`. A new user event keeps its `fflags` unmasked and is not triggered by `NOTE_TRIGGER`, because `filt_userattach` reads the already cleared `kn_fflags`. The timer limit `kq_calloutmax` (`ENOMEM`) is not enforced, and closing a kqueue wakes a thread waiting on it in `kevent` with `EBADF`, where `kqueue_drain` makes the close wait for that thread. A level-triggered event is reported once per call and moved behind the other events, as in `kqueue_scan`; the `sceKernel*Equeue` calls keep their own collection loop. `NOTE_LOWAT` on a socket sets the low-water mark as FreeBSD 11's [`filt_soread` and `filt_sowrite`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/uipc_socket.c) do, and a later change of the knote replaces it as `kqueue_register` replaces `kn_sdata`: a read event fires once the buffered bytes reach the mark, or at end of file or on a listening socket. A write event takes a mark of 1 only, where the host's writability stands in for one free byte, since the host does not report the send buffer's free space; other write marks and marks below 1, which make FreeBSD's read filter always fire, throw

 - [EVFILT_VNODE, sceKernelAddFileEvent and sceKernelDeleteFileEvent](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) (libkernel) watch the host file or directory behind the descriptor and turn host changes into FreeBSD 11 vnode hints, which [`filt_vfsvnode`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L5032) adds whole when they share a bit with the requested `fflags`: a write that grows a file is `NOTE_WRITE | NOTE_EXTEND`, another write `NOTE_WRITE`, a shrinking truncate or an attribute change `NOTE_ATTRIB`, a higher link count `NOTE_LINK`, a lower one or a pending delete `NOTE_DELETE`, a new path `NOTE_RENAME`; in a directory, an entry created, removed or renamed is `NOTE_WRITE`, with `NOTE_LINK` for a subdirectory, and on Linux an entry moved from or to another directory adds `NOTE_EXTEND`; inotify queues the two halves of a rename one after the other, so a watcher woken by the first can read it alone, and a half read without the other is classified only after a `getdents64` on the watched directory, which takes the directory lock that `rename` holds until both halves are queued ([`do_renameat2`](https://github.com/torvalds/linux/blob/v6.8/fs/namei.c#L4975) around `vfs_rename` and its `fsnotify_move`, [`iterate_dir`](https://github.com/torvalds/linux/blob/v6.8/fs/readdir.c#L103)), an ordering taken from the kernel source, not from inotify(7), which promises none; a directory registered with `NOTE_EXTEND` on Windows is accepted, as `vfs_kqfilter` does not check it, but never receives it, because the directory handle cannot tell a move between directories from a removal plus an addition. FreeBSD's hints depend on the filesystem and the console's filesystems are not known: a growing `ftruncate` reports `NOTE_WRITE | NOTE_EXTEND` where `vop_setattr_post` reports `NOTE_ATTRIB`, and on Windows `utimes` on a file reports `NOTE_WRITE`. The three Windows notifications are told apart in the error, which names the `parent`, `entries` or `subdirectories` watch, the path it was given and `GetLastError`, but a `FindFirstChangeNotification` that fails still throws rather than returning an error to the guest: the EVFILT_VNODE attach path is [`vfs_kqfilter`](https://github.com/freebsd/freebsd-src/blob/34bd34750187bae02a0086402c78c031c59dd8b3/sys/kern/vfs_subr.c#L4936), which returns `EINVAL`, `ENOMEM` or 0 after `fget` has turned a descriptor that is not open into `EBADF`, and consults no directory permission, so no FreeBSD errno stands for a host that refuses to notify, and what the console does on such a host is not measured. Only the `parent` watch can fail this way in practice: `entries` and `subdirectories` need the `FILE_LIST_DIRECTORY` that opening the watched directory already took. The parent handle produces no hint of its own, as `RunHostWatch` only calls `FindNextChangeNotification` on it, so a later change may leave the watch on its 50 ms poll instead of throwing; that is not done here. Windows uses `FindFirstChangeNotification` on the parent directory (and on a watched directory itself) and compares `GetFileInformationByHandleEx` snapshots at least every 50 ms, because a write through an open handle is reported only when the handle is flushed or closed, so file hints can arrive 50 ms late, and a file deleted while watched, which the POSIX delete of Windows 10 1903 moves into `$Extend\$Deleted` until its last handle closes, reports `NOTE_DELETE` without `NOTE_RENAME` and keeps its handle without a parent directory watch, as that directory cannot be watched; Linux uses inotify on the file and is not run. `NOTE_REVOKE`, `NOTE_OPEN`, `NOTE_CLOSE`, `NOTE_CLOSE_WRITE`, `NOTE_READ`, unknown bits and descriptors other than files, directories, pipes and sockets throw. `sceKernelAddFileEvent(eq, fd, watch, udata)` and `sceKernelDeleteFileEvent(eq, fd)` take the [OpenOrbis](https://github.com/OpenOrbis/OpenOrbis-PS4-Toolchain/blob/0a1aaf9d/include/orbis/libkernel.h#L35) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0/src/SharpProspero/Interop/Kernel/KernelEqueue.cs#L164) signatures; `watch` is taken as the `fflags` and the event is added with `EV_CLEAR`, neither confirmed on a title (feat(libkernel): implement kevent EV_DISABLE, EV_DISPATCH and EV_FORCEONESHOT) (fix(libkernel): follow kqueue_register for EV_FORCEONESHOT and modify flags)
 - [sem_timedwait](../../../core/libs/prx/libkernel/Pthread/Posix/Sem.cpp) (libkernel) consumes an available count before checking the timeout and waits indefinitely for a null timeout, following FreeBSD 11's `sem_timedwait`. Console behavior for null and invalid timeouts when a count is available is unverified.
 - [tcsendbreak, tcdrain, tcflush, tcflow, tcgetpgrp, tcsetpgrp](../../../core/libs/prx/libkernel/File/src/Terminal.cpp) (libkernel) follow FreeBSD 11.4's [`termios.c`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/gen/termios.c): `tcflush` answers `EINVAL` for a queue other than `TCIFLUSH`, `TCOFLUSH` or `TCIOFLUSH` and `tcflow` for an action outside `TCOOFF`..`TCION` before the descriptor is looked at, and every other call fails as its terminal ioctl does on a descriptor that is not a terminal, with the errors `tcgetattr` gives, so `tcsendbreak` never reaches its 0.4 s pause. FreeBSD's `pipe_ioctl` answers `TIOCGPGRP` and `TIOCSPGRP` on a pipe or FIFO with the descriptor's SIGIO owner, which is not modelled, so `tcgetpgrp` and `tcsetpgrp` throw on a host pipe or FIFO above descriptor 2; descriptors 0 to 2 are taken as non-terminals that are not pipes, whatever the host attaches to them, so a pipe the guest creates on a freed descriptor 0 to 2 gets `ENOTTY` there. The PS5 `libkernel` is assumed to use this FreeBSD code, and `tcdrain` is not a cancellation point here

 - [memcpy_s and memmove_s](../../../core/libs/prx/libc/src/Strings.cpp) (libc) use the C11 K.3.7.1.1 and K.3.7.1.2 size constraints, with RSIZE_MAX taken as SIZE_MAX >> 1 as in memset_s. An oversized destination size returns ERANGE (34) without touching the destination; the console's RSIZE_MAX and exact error value are unverified. Constraint violations return an error without invoking the registered constraint handler, as before.
 - [snwprintf_s](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - follows C11 K.3.9.1.3 with `RSIZE_MAX` assumed to be `SIZE_MAX >> 1`. A runtime-constraint violation only returns a negative value: `set_constraint_handler_s` is not exported and the console's default handler is unknown. An invalid multibyte `%s` argument is copied byte by byte instead of being reported as an encoding error, as in `vswprintf`
 - [swprintf_s and vswprintf_s](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - follow C11 K.3.9.1.4 with `RSIZE_MAX` assumed to be `SIZE_MAX >> 1`: the complete output, including the terminating null, must fit in the buffer, otherwise it is a runtime-constraint violation that sets `buffer[0]` to zero and returns a negative value, and the buffer is not partially written. Argument and encoding checks match `snwprintf_s`
+- [strerror_s and strerrorlen_s](../../../core/libs/prx/libc/src/WideConversion.cpp) (libc) follow [C11 K.3.7.4.2 and K.3.7.4.3](https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf), using the existing FreeBSD error messages and unknown-error formatting. Truncation writes an ellipsis when capacity exceeds 3; constraint failures leave the destination untouched and invoke the registered guest-ABI handler. The console's `RSIZE_MAX` (`SIZE_MAX >> 1` here), nonzero returns (`EINVAL` 22 for constraints, `ERANGE` 34 for truncation), handler arguments and default abort behavior are unverified. Messages remain in the C locale, and guest errno is preserved.
 - [vsnwprintf_s](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - `va_list` counterpart of `snwprintf_s` (C11 K.3.9.1.3): truncates to the buffer and returns the full length, with the same constraints and argument checks
 - [vsnprintf_s and vsscanf_s](../../../core/libs/prx/libc/src/Formatting.cpp) (libc) - `vsnprintf_s` forwards to `vsnprintf` semantics: the C11 K.3.7.1.5 runtime constraints (null buffer, `size == 0`, `%n`, null `%s`) are not checked, so `size == 0` returns the would-be length instead of a negative value, and no constraint handler is invoked. `vsscanf_s` returns the count of items converted before an undersized `%s`/`%c`/`%[` destination (0 when it is the first), not EOF. Neither is confirmed on a PS5 title
 - [strndup and strdup](../../../core/libs/prx/libc/src/AllocatingStrings.cpp) (libc) return null with `errno` set to `EINVAL` (22) when `source` is null, preventing a host segfault on invalid guest input. POSIX.1-2008 and FreeBSD 11.4 libc leave `strndup(NULL)` and `strdup(NULL)` undefined (faulting); exact console behavior on hardware is unverified.

Subject: [PATCH 0706/1000] feat(pad): touch the left or right touchpad half
 from the input command file

APS5_PAD_INPUT_FILE commands can set bit 0x200000 or 0x400000 to put a
finger on the left or right half of the touchpad, as the TouchLeft and
TouchRight keys do, so scripted runs can press touchpad combinations.
tools/pad_input.py queues them as touch-left and touch-right.

A press lasts 300 ms by default, starting when the application reads it, and releases automatically; `--hold-ms` accepts 1–5000 ms. `--left-stick X Y` and `--right-stick X Y` hold the sticks for the same time: each axis is 0-255, 128 is the centre, X grows to the right and Y grows downward.

Subject: [PATCH 0708/1000] fix(agc): keep the mesh index descriptor on
 relocated draw stages

relocateDrawEntry copied a cached variant field by field and left out
meshIndexDescriptor, which the variant gained in #5791 before #4943 merged.
lookupDraw compares a mesh stage's descriptor with the draw's index buffer
words before validating anything else, and no draw has an all-zero one, so
every relocated mesh-path stage was refused as a differing front stage. With
no hits the shader set's relocation trial stopped admitting new aliases too.

The copy now takes the donor's descriptor, so a relocated mesh stage matches
the same index buffer the donor was built for and misses on any other.

agc_driver_mesh_draw_relocation draws a mesh-path triangle whose vertex
buffer descriptor is loaded through a user-data pointer, at eight addresses
with the same contents: the last four now hit the cached draw (before: four
differing front stages, no hit).

Subject: [PATCH 0711/1000] test(agc): check that a read through the BDA table
 sees a target as with its pass broken

Continuing a pass across a draw that only reads through the table is
right only if no pass end records a target write-back that the read
depends on. agc_driver_address_passes --targets renders a color whose
bytes spell 1.0f into the target, then reads the target's first dword
through the table into the same target, once with a tiled target and
once with a linear one.

The tiled read continues the rendering draw's pass and reads the bytes
from before it: tiled results reach guest memory only by explicit
write-backs, none of which falls between the two draws. The linear read
reads the rendered color: a linear target over a host import is stored
back right after its draw (the store ends the pass), and one without an
import is drawn synchronously. agc_driver_address_passes_targets_split
runs the same cases with APS5_NO_ADDRESS_READ_PASSES=1 and must read the
same bytes; a scratch build that writes the targets back whenever a
draw reading through the table breaks the pass fails it.

+- [sceVideoOutColorSpaceConversionSettingsSetDefaultSdrToHdrConversion_, sceVideoOutColorSpaceConversionSettingsSetSdrToHdrConversion_, sceVideoOutAdjustColorSpaceConversion_, sceVideoOutSetGlobalBlendSpace](../../../core/libs/prx/libSceVideoOut/src/Output.cpp) (libSceVideoOut) - PPSA30630 imports these to configure color space conversion and global blend space. Color space conversion settings are accepted with size validation (32 bytes) but conversion blocks and blend space parameters are not applied to the presentation swapchain
 - [sceVideoOutDeleteVrrActiveStatusEvent](../../../core/libs/prx/libSceVideoOut/src/Event.cpp) (libSceVideoOut, NID `-q-vbO859Tw`) - the name hashes to the NID PPSA02530 imports and is listed in [sce_symbols](https://github.com/zecoxao/sce_symbols) `aerolib.csv` at `fe2cc2948e`. The signature `(eq, handle)` and the behaviour, removing the handle's VRR status registration from the queue as the other `Delete*Event` calls do, follow sceVideoOutAddVrrActiveStatusEvent; no title has been observed calling it
 - [sceVideoOutGetOutputStatusWithVrr](../../../core/libs/prx/libSceVideoOut/src/Output.cpp) (libSceVideoOut, NID `gWT7X8H0bYs`) - `(int handle, void* status)`, the 80-byte layout and the return codes follow the clean-room description in #2746. Bytes 0-47 are `sceVideoOutGetOutputStatus`'s; bytes 48-53, which the console copies from an internal query whose fields are not established, are written as zero, as are the rest, so the 16-bit value at byte 52 never adjusts `refreshRate`. A null `status` returns `0x80290002` and an unknown handle `0x8029000B`. The console's earlier global-flag check (`0x8029001C`) and its object-field check (`0x8029001B`) test states that are not modelled and are never reported.
 - [sceVideoOutRegisterBuffers2](../../../core/libs/prx/libSceVideoOut/src/Buffer.cpp) (libSceVideoOut) - buffer option 8 (STRICT_COLORIMETRY) is presented as option 0, with the stored values unchanged; what the console changes for it is unknown. Only options 0 and 8 are accepted

Subject: [PATCH 0713/1000] fix(agc): keep the template of another address when
 a dispatch move is refused

Read-only addresses are not part of the dispatch key, so the fresh build after a refused
move replaced the template that serves the other address, and the two addresses
rebuilt each other. A refused dispatch now uses or builds an entry under the exact key
(read-only bases included) and leaves the movable template alone. The [dispmove] line
counts the rebuilds after a refusal, the builds inserted beside the template and the
dispatches served by an exact entry. Restores the MarkGpuWrites comment.

 links

lstat and readlink aborted on an absolute symbolic link because only a relative reparse point was accepted. Read the link text, and still refuse reparse points that are not symbolic links.

Subject: [PATCH 0718/1000] fix(libkernel): measure the host stack reserve from
 the frame address

MeasureStackReserve took the distance from the stack top to a local
variable. In an ANYPS5_ENABLE_ASAN build that local lives on
AddressSanitizer's fake stack (detect_stack_use_after_return is on by
default on Linux), away from the thread's stack, so the reserve could
come out negative. scePthreadCreate then asked the guest arena for a
stack of nearly 2^64 bytes and threw 'guest address space arena
exhausted'. The frame address is on the real stack in every build.

Subject: [PATCH 0723/1000] fix(shader): take 16-bit interpolation to the
 barycentric emulation without the extension

v_interp_p1ll_f16, v_interp_p1lv_f16 and v_interp_p2_f16 read each
vertex's parameter and threw on a device without
VK_KHR_fragment_shader_barycentric. Without the extension the pixel
shader is translated once for fixed-function interpolation and, when
that cannot express it, again with the barycentric emulation, whose
generated geometry stage passes each vertex's parameter as a flat input.
The throw came in the first pass, before the second could run. Without
it the 16-bit parameters keep the shader off fixed-function
interpolation, so it takes the emulation and reads the halves bit for
bit, as v_interp_mov_f32 already does.

active instead of throwing, and with them it does not take it. The
offline target declares Float64, which the exact interpolation sums use.

On a device without VK_KHR_fragment_shader_barycentric the draw now
builds the emulation's geometry stage and checks the same results in
wave64 and wave32 as on a device with the extension. It skips only on a
device with neither the extension nor geometry shaders, or without the
Float64 capability the exact sums need.

 - [Mesh shader grid size](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - every mesh shader loads `NumWorkgroups.x` and declares no vertices when it is 0, which no dispatch produces. The read is a workaround for RADV (Mesa 26.2.4, seen on an RX 9070 XT, GFX12): binding a mesh pipeline whose shader reads neither `NumWorkgroups` nor `DrawIndex` keeps the user SGPR count and draw-id flag of the vertex pipeline bound before it in the same command buffer (`radv_bind_pre_rast_shader` updates them only when the shader has the `AC_UD_VS_BASE_VERTEX_START_INSTANCE` slot), so `radv_emit_userdata_mesh` opens a 3-register `SET_SH_REG` and writes one value, the CP takes the following `DISPATCH_MESH_DIRECT` as register data and the GPU hangs (gfx ring timeout, MODE1 reset). Kena: Bridge of Spirits (PPSA01802) hits it on its layered volume draws. Reading `NumWorkgroups` gives every mesh shader the grid-size slot, so the count and the values match; drop the read once a fixed Mesa is the minimum

Denormal modes 1 and 2 (flush only inputs or only outputs) and rounding other than to nearest even are not measured and throw. An unknown mode follows IEEE=0 with denormals kept.

Any other read of them or of a raw vertex parameter takes the weights and the three vertex values from a [generated geometry stage](../../../core/shader/recompiler/SpirvBackend/src/BarycentricGeometryShader.cpp), which needs `geometryShader` and a vertex shader before it: tessellation, mesh and rect-list pipelines, primitives other than triangles, more than 32 fragment input locations and interfaces beyond the device's geometry limits throw.

The f16/f64 denormal field of `FLOAT_MODE` (bits 7:6) is not read: when it flushes, the hardware flushes the operands and the result of `v_fma_f64` (tininess before rounding) and only the result of `v_div_fmas_f64`, while these keep them. Shaders with f64 instructions declare `DenormPreserve` for 64-bit floats only when `shaderDenormPreserveFloat64` is true and Vulkan reports `denormBehaviorIndependence` as `ALL`; other independence modes are not handled by the current backend because they require coupled execution modes. See [VkShaderFloatControlsIndependence](https://docs.vulkan.org/refpages/latest/refpages/source/VkShaderFloatControlsIndependence.html). Elsewhere (including lavapipe), the driver may flush f64 subnormals, and `agc_driver_f64_fma_subnormals` is skipped.
 - [SINT storage images](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) of 8- and 16-bit components saturate each stored 32-bit value to the component range, as adriadam10 measured for image stores on RDNA2 (gfx1035) in #944 (448 rows match); the PS5's gfx1013 is not measured. A D16 store sign-extends each 16-bit half before that saturation, as measured on RDNA2 (gfx1035) for `image_store d16` to all eight SINT formats with DMASK 0xf, 0x7, 0x5, 0x3, 0x2, 0xa and 0x1 (1792 rows match).

Subject: [PATCH 0727/1000] feat(libSceContentDelete): add sceContentDeleteById

Cult of the Lamb (PPSA06465, #2686) stops at start-up on the first one:

    FAIL: unresolved ELF import pXJh3aVk8Ks from libSceContentDelete.prx

Both exports have been on main without an implementation (#2740); the
call itself has not been observed yet.

Orbital (cc408367, tools/ida/db_types.json:541-542) and SharpProspero
(5dfdb4b0, Interop/Content/ContentDelete.cs:25-42) agree on the
signatures: a 64-bit SceContentSearchContentId and a UTF-8 path. The
content library is empty on the host, since libSceContentExport exports
nothing into it, so no id or path can be found. SharpProspero gives only
NoPermission (0x809D5006) and no public source gives the not-found code,
so both calls throw with the id or path named once the null path and the
initialization are checked, like the "not in the host content library"
throws of #3724. sceContentDeleteById moves from
guest_content_unimplemented to the new guest_content_delete test.

NIDs pXJh3aVk8Ks and qC3QW+AltHs match tools/nid_names.py and the shadPS4
aerolib list.

-- [sceContentDeleteById](../../../core/libs/prx/libSceContentDelete/Export.cpp) (libSceContentDelete) - imported by PPSA06465, which fails to load without it; added without an implementation because its signature is unknown
+- [sceContentDeleteById and sceContentDeleteByPath](../../../core/libs/prx/libSceContentDelete/Export.cpp) (libSceContentDelete) delete from a content library that is empty on the host, as nothing is exported to it, so both throw for every content id and path once the arguments and the initialization are checked: no reference gives the console's error for content that is not in the library ([SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Content/ContentDelete.cs#L25-L42) names only `0x809D5006`, no permission). The signatures, a 64-bit content id and a UTF-8 path, follow [Orbital](https://github.com/AlexAltea/orbital/blob/cc408367da6a6ebbf5ac1ac559fefeadc73b2831/tools/ida/db_types.json#L541-L542) and SharpProspero, which agree. A null path and a call outside `sceContentDeleteInitialize` and `sceContentDeleteTerminate` throw, as the console's errors for them are unknown, and the order of the two checks is unverified.

Subject: [PATCH 0729/1000] fix(libkernel): end guest thread, fiber and context
 frame chains at a zero record

Unreal Engine walks the frame-pointer chain until it reads a return
address of 0 and never checks the frame pointer itself. Guest threads
started with whatever rbp the host code held, so the walk ran into host
start-up frames (glibc's saved rbp 0x21 in a LEGO Batman core dump,
address 8 in Returnal on Windows) and faulted. Fibers ended their chain
with a null frame, and makecontext started its function with rbp 0, so
the same walker read address 8 there too.

Guest threads now start through a thunk that points rbp at a
{saved rbp 0, return address 0} record, as the relinker's entry stub
does for the main thread; the fiber trampolines push the same record,
and the makecontext start function is built with frame pointers so its
frame, over the zero return address makecontext stores, ends the chain.

Subject: [PATCH 0730/1000] fix(shader): forward gl_ClipDistance through the
 generated rect-list stages

Since #3878 every vertex program that exports a position also writes
gl_ClipDistance for the all-zero position distance. The tessellation
stages generated for rect lists declared only gl_Position in gl_in, so
their input interface no longer matched the vertex outputs; on MoltenVK
the control stage then reads all-zero positions and every rect-list
draw stops with "rect-list requires finite nondegenerate axis-aligned
positions" (reported in #1).

The control and evaluation stages now declare the vertex program's
gl_ClipDistance array in their per-vertex blocks and forward it. The
generated fourth corner gets the clip distances interpolated with the
same weights as its position, so the all-zero position clip keeps
working for rect lists. Validation accepts gl_ClipDistance as a
tessellation input and as a tessellation-control output.

 - [sceRudpGetStatus](../../../core/libs/prx/libSceRudp/Export.cpp) - PPSA01521 passes an output pointer and byte count `0xF8`. Measured on a PS5 (firmware 13.60): the status is 0xF8 bytes; before `sceRudpInit` every call returns `RUDP_ERROR_NOT_INITIALIZED`, and after it a null pointer or a byte count of 0 or above 0xF8 returns `RUDP_ERROR_INVALID_ARGUMENT`. The layout matches `SceRudpStatus` in [Vita3K](https://github.com/AndnixSH/Vita3K-PS-Vita-OS-Fork/blob/master/vita3k/modules/SceRudp/SceLibRudp.cpp) with `currentContexts` at 0x64 and `allocs`, `frees`, `memCurrent` and `memPeak` at 0xC8 to 0xD4. Only `currentContexts` is reported: the traffic counters stay 0 because nothing is sent, and the allocator counters stay 0 because the library does not allocate from the title's pool (the console reports 6 allocations and 0x1260 bytes right after `sceRudpInit`, and 4 more allocations and 0x3F0 bytes per context). The console also writes `currentContexts` and the allocator counters when the byte count is smaller than their offset; only the requested bytes are written here.

The library keeps no configurable segment size (there is no `sceRudpSetMaxSegmentSize`), so 1410 is always reported. The `uint16_t*` parameter is inferred: the measurement does not show how many bytes the console writes, PPSA03490 passes a pointer to a 16-bit value and [RPCS3](https://github.com/RPCS3/rpcs3/blob/master/rpcs3/Emu/Cell/Modules/cellRudp.cpp) declares the PS3 `cellRudpSetMaxSegmentSize(u16 mss)`, so only 16 bits are written

Subject: [PATCH 0732/1000] fix(agc): clear the host depth image on a fill of a
 depth or stencil plane

A fill that covers a depth surface's whole stencil plane with four equal
bytes, or its whole depth plane with a value in 0.0-1.0, now reaches the
host image through the pending fast clear the next time the surface is
bound, sampled or stored to. An HTILE fill or HTILE clear kernel noted
afterwards replaces the value with DB_DEPTH_CLEAR/DB_STENCIL_CLEAR.
NoteDepthMetadataFill only reacted to fills of DB_HTILE_DATA_BASE, so the
Cohtml UI of Heretic + Hexen (PPSA26525) and DOOM + DOOM II (PPSA21444),
which resets its stencil plane to 1 with a 0x01010101 fill every frame and
then draws with stencil Equal 1 and 2, kept the stencil of earlier frames
and showed black squares and clipped text. agc_driver_depth_plane_fill
pins the rules.

 - [HtileFillCovers](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - a fill is taken to cover a depth surface's whole HTILE when it spans 32 KiB per 1024x512 pixel block from DB_HTILE_DATA_BASE, the pipe-aligned SW_64KB_Z_X metadata extent AMD PAL's gfx10 addrlib gives for GB_ADDR_CONFIG 0x00100044 (1-8 samples, D16/D32); other metadata layouts are not decoded. A partial fill is ignored (the surface keeps its contents); not measured on the console.
 - [Depth fast clear through HTILE](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - a surface cleared by an HTILE fill is cleared to DB_DEPTH_CLEAR, also when it is next sampled. For a depth-only HTILE the clear word also carries a value (radv writes `minz = maxz = round(depth * 0x3fff)`, `HTILE_Z_CLEAR_REG` in Mesa's `src/amd/common/ac_descriptors.h`, and allows TC-compatible fast clears only to 0.0 or 1.0); which of the two the texture unit returns for a cleared tile was not measured.
 - [Depth-only and stencil HTILE fill](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - in a whole-HTILE fill, ZMask (bits 0-3) 0 clears the depth and SMem (bits 8-9) 0 clears the stencil, while SMem 3 leaves the stencil alone (`HtileFillClears`); other SMem values are taken to leave it alone too. The bit meanings follow the gfx10 HTILE layout as the code reads it, not a measurement; `agc_driver_depth_fast_clear_submit` pins them for the paths the Driver takes.
+- [Depth and stencil plane fills](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - a fill that covers a known depth surface's whole stencil plane (`DepthSliceBytes` of its extent at one byte per texel) with four equal bytes clears the host stencil to that byte the next time the surface is bound, sampled or stored to, and a fill that covers the whole depth plane (two or four bytes per texel) clears the depth when the dword is a float in 0.0-1.0, or two equal 16-bit halves read as UNORM for D16 (`NoteDepthMetadataFill`). A partial fill, a dword whose bytes differ, a depth value outside 0.0-1.0 (0xff000000 is seen), a multisampled surface, or a fill made before the surface exists leave the host image as it was. An HTILE fill or a recognized HTILE clear kernel noted after a plane fill replaces its value with DB_DEPTH_CLEAR/DB_STENCIL_CLEAR. On the console the fill writes the plane the depth block reads; the surfaces this was seen on keep the stencil out of HTILE (PPSA26525 Heretic + Hexen and PPSA21444 DOOM + DOOM II reset the Cohtml UI stencil plane to 1 with a 0x01010101 fill every frame, then draw with stencil Equal 1 and 2), and what the console returns for a plane fill under a compressed HTILE was not measured. `agc_driver_depth_plane_fill` pins the rules.
 - [HTILE address of a depth array slice](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - `decodeDepth` adds the `DB_DEPTH_VIEW` slice offset to the Z and stencil addresses but not to `htileAddress`, so every slice of a layered depth target shares slice 0's HTILE address and a fill of slice 0's HTILE marks all slices cleared. Astro's Playroom fills the HTILE of each of its three shadow cascades 0x40000 apart (0x24000 bytes of tiles each) back to back before drawing, so the result is still right there; a title that clears one slice between draws to another would lose depth. The per-slice HTILE stride is not derived yet.
 - [sceAgcDriverGetHsOffchipParam](../../../core/libs/prx/libSceAgcDriver/Unimplemented.cpp) (libSceAgcDriver, NID `r28hEh6cNH0`) - declared as a throwing stub. The two `uint16_t` output pointers and integer return type follow [ps5-vulkan](https://github.com/blackbearreloaded/ps5-vulkan/blob/4bb0c8b1423698a7369efc22b829bf16a99e7128/native/tess_driver_import_stub.c#L10), which reads the pair before it binds a tessellation factor ring. The meaning of the two values, their initial state and how they relate to `sceAgcDriverSetHsOffchipParam`, which keeps nothing here, are unknown; the stub does not write caller memory. PPSA99011 imports it
 - [Vertex input and color target overlap](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (AGC driver) - direct draws exclude the descriptor prefix skipped by `firstVertex` or `firstInstance` from the alias check; indexed draws conservatively use index zero as the lower bound before adding `firstVertex`. Indirect draws still check the full descriptor extent. Reads of the active target's bytes remain unsupported; same-draw console ordering is not established.

 The report also lists needed libraries that have no file in `--libs` or `--modules`, including dependencies with zero imports. These do not increase the import or reference counts. Windows can skip a missing dependency when no import needs it; Linux still needs the file. The audit also lists imports exported only by a library other than the one they name; those resolve on Linux and can fail on Windows.
 
+The audit also walks the built libraries' own host dependencies: each `.prx` under `--libs` has its PE imports (or ELF `DT_NEEDED` entries) checked for `.prx` names with no file in `--libs` or `--modules`, following present libraries transitively. Gaps fail the audit and are reported as `Importer: <root> Chain: <root> -> ... -> <missing>` lines, since the loader fails on them even when every game import resolves.

Subject: [PATCH 0735/1000] fix(shader): write cache files of 2 GiB and more in
 chunks

On Windows (MinGW libstdc++) one std::ofstream::write of 2 GiB or more
never returns: the whole temporary file is written but WriteFileAtomically
hangs, the entry is never replaced and the temporary file stays behind.
A Vulkan pipeline cache of 2.1 GB hung every save and left a 2 GB .tmp
per run. Write in chunks of at most 1 GiB.

An expiry delivers nothing: with `SIG_IGN` it is dropped, with the default disposition the process exits with status 142, and with a handler, or with `SIGALRM` blocked, it throws, since guest `SIGALRM` handlers are never run and signals are never left pending. The value is not raised to `tick / 16` as `itimerfix` does, and an interval below 1 ms throws, since the console's `hz`, and so that rounding, is unknown (1 ms covers any `hz` of 63 or more). `ITIMER_VIRTUAL` and `ITIMER_PROF` throw when armed, as process CPU time is not accounted, and read and disarm as zero. PPSA99420 imports it and fails to load without it
 - On Linux, [direct memory](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) lives in one sparse memfd at file offset = physical address, so the [GPU imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) can share one udmabuf buffer object per 64 MiB of it. Released direct memory is not punched out of the file, because a live import of its chunk pins the pages and the GPU would keep reading the old ones: its pages stay committed (the process keeps the high-water mark of the direct memory it used) and are zeroed when the range is allocated again.
 - [system](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) runs no command. It follows FreeBSD 11's `lib/libc/stdlib/system.c` for a sandbox without `/bin/sh`: a null command returns 1 unconditionally, as that version does, and any command returns the wait status of a child that could not exec the shell and called `_exit(127)` (`0x7f00`). Whether the console's application sandbox has no shell, and whether `vfork` succeeds there (FreeBSD returns -1 when it fails), is unverified
-- [sceKernelWriteThrottlingStatus](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) reports no write throttling: the host SSD has no write budget, so the first qword of the 32-byte status is set to `UINT32_MAX` and the rest is zeroed. PPSA17221 reads only that qword: it multiplies it by 64 KiB and compares the product with byte thresholds up to 0x4AF00000 to pick one of five tiers. When the call fails the title assumes 0x4B000001 bytes, which selects the same top tier as `UINT32_MAX`. What the value measures on hardware (a remaining budget or a rate) and the meaning of the other three qwords are unknown

 - [Windows directory descriptors](../../../core/libs/prx/libkernel/File/src/DirectoryDescriptor.cpp) (libkernel) take one snapshot of the directory, on the first `getdents`, `getdirentries` or non-zero `lseek` (`SEEK_SET` or `SEEK_CUR`), and keep it until it is discarded; `lseek` to offset 0 only discards the snapshot, and the next read lists the directory again, so every rewind costs O(entries) on the next read. `lseek` takes the offset as an entry index and `SEEK_CUR` with offset 0 only reports the index. `SEEK_END` throws, where the NUL descriptor used to return 0, because FreeBSD defines it relative to the directory size, which is not modelled. A negative result returns `EINVAL` and a `SEEK_CUR` offset that overflows returns `EOVERFLOW`, as FreeBSD `vn_seek` reports them. Names whose UTF-8 encoding exceeds the one-byte `d_namlen` limit are not representable in this guest directory-record layout: `getdents` returns `ENAMETOOLONG` without consuming the entry. Repeated calls therefore report the same error and entries after that name cannot be reached through this descriptor; FreeBSD's `getdents` behavior for host filenames that exceed its `MAXNAMLEN` is not verified. `getdirentries` still reports 0 through `basep` instead of the position of the block it read, so only 0 and values returned by `lseek` are valid offsets; FreeBSD offsets are filesystem cookies
 - [/dev/random and /dev/urandom](../../../core/libs/prx/libkernel/File/src/RandomDevice.cpp) (libkernel) opened for reading return a descriptor backed by the host null device whose reads are filled with host OS entropy (`getentropy`, `rand_s` on Windows); both paths behave the same, never block, and positioned reads ignore the offset (FreeBSD `random(4)`). Only the exact paths are recognised, `fstat`, `lseek` and `mmap` see the null device, and opening them for writing throws
 - [pthread_mutexattr_getpshared and pthread_mutexattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Mutex.cpp) (libkernel) store and report private or shared attributes, following FreeBSD 11 libthr [thr_mutexattr.c](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libthr/thread/thr_mutexattr.c). Invalid values return `EINVAL` without changing the attribute. Guest threads execute in one host process; sharing mutexes across processes is not modeled. Console behavior and invalid-attribute error precedence are unverified.

Subject: [PATCH 0737/1000] fix(agc): wake an idle queue 0 for completions the
 draw pipeline adds

With pipelined draws, queue 0 hands the end-of-pipe labels of a
submission to the draw pipeline and can enter its idle wait before the
pipeline commits them. When such a label raises an end-of-pipe
interrupt behind recorded work, the pipeline attaches the delivery to
the batch as a completion and submits it, but queue 0 only reaps when
it saw completions pending before it went to sleep, and nothing woke
it. The batch was then reaped, and the interrupt delivered, only when
the next submission arrived, so a title that waits for that interrupt
before submitting more work stopped.

Queue 0's idle wait now also ends when completions are pending, and
the pipeline's end of a submission (and the REWIND path's open-work
submit) wakes it when they are.

Subject: [PATCH 0740/1000] feat(libkernel): poll regular files and directories
 as vop_stdpoll does

poll threw for any descriptor that is neither a socket nor a pipe, so a title polling a file it also reads stopped there. FreeBSD 11.4 hands a vnode to VOP_POLL, and both vop_stdpoll and vop_nopoll return POLLIN, POLLRDNORM and POLLOUT of the requested events for every event poll accepts and never POLLPRI, POLLRDBAND or POLLWRBAND. A file, a directory or a file read from app0.zar now answers that without a host call. File::IsVnode tells such a descriptor apart from the host file type without throwing, so a host socket lent by libSceNet still reaches its own path.

 - [read, write and vector I/O](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on a guest socket use `recv` and `send` without flags; `sceKernelReadv` and `sceKernelWritev` gather or scatter through one socket operation, preserving stream short reads and datagram boundaries. The positioned `pread`, `pwrite`, `preadv` and `pwritev` forms, and their `sceKernel` forms, return `ESPIPE` for an open guest socket and `EBADF` for a closed one. `EPIPE` from a write raises the host's `SIGPIPE` on Linux unless the socket has `SO_NOSIGPIPE` set, and the guest cannot ignore it: `signal(SIGPIPE, SIG_IGN)` and `sigaction` record the disposition, as they do for every number from 1 to 128, but only the six signals with host equivalents (2, 4, 6, 8, 11 and 15) take effect on the host or are delivered, so the host `SIGPIPE` is not stopped; nothing is raised on Windows; a `write` longer than `INT_MAX` bytes is `EMSGSIZE` where the console sends it. AIO on a guest socket still goes to the host, which has no such descriptor
 - [Socket descriptor numbers](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel, libSceNet) - `socket`, `accept`, `socketpair`, `dup`, `sceNetSocket` and `sceNetAccept` take the lowest free number of the host descriptor table that files use, as FreeBSD 11.4 `fdalloc` takes the lowest free entry of the one process table (`kern_descrip.c`), so every number stays below `FD_SETSIZE` (1024) while fewer than 1024 descriptors are open. The number holds a zero-access `NUL` handle on Windows and a duplicate of the host socket on Linux, and the socket tables map it to the socket. The host table also holds the runtime's own files, so the numbers differ from the console's; the first number `socket` and `sceNetSocket` return on a console and its `getdtablesize` are not measured. Paths that bypass the socket tables see the placeholder: libc `fdopen` on a socket opens it, and libkernel `close` of a libSceNet socket releases the number but leaves the libSceNet socket open. Palworld (PPSA23126), The Mound (PPSA26223) and Dying Light 2 (PPSA02262) set socket bits in a 1024-bit `fd_set`
 - [fstat on a guest socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) fills the fields FreeBSD 11's soo_stat and pru_sense_null fill and zeroes the rest: S_IFSOCK, the read bits while the receive side is open or data is queued, the write bits while the send side is open, st_size and st_blksize. Only this process's shutdown closes a side here; a peer's shutdown, close or reset does not clear the bits as FreeBSD's socantrcvmore and socantsendmore do. st_size is the host's FIONREAD, which for a Linux datagram socket is the size of the next datagram where FreeBSD counts every queued byte, and st_blksize is the host's SO_SNDBUF, which Linux reports as twice the size that was set. A socketpair end reports st_dev and st_ino 0, where FreeBSD's uipc_sense reports NODEV and a per-socket number
-- [poll](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) waits on guest sockets and pipes, through `WSAPoll` on Windows and `poll` on Linux; the `pollfd` layout and flag values are FreeBSD's. A libSceNet socket joins the same host wait through the native socket libSceNet lends to libkernel. `WSAPoll` rejects `POLLPRI`, so on Windows a socket's `POLLPRI` is asked as `POLLRDBAND` and `POLLIN` as `POLLRDNORM`; Winsock reports urgent data until it is read with `MSG_OOB`, where FreeBSD 11.4's `sopoll_generic` stops once the normal stream passes the mark. Guest `send` and `recv` refuse `MSG_OOB` with `EOPNOTSUPP`, so urgent data can only come from an outside peer and Windows keeps reporting `POLLPRI` after the stream passes the mark. A pipe follows FreeBSD's `pipe_poll`: the read end is readable when data is buffered, either end reports `POLLHUP` once the other end is closed, with the requested `POLLIN` and `POLLRDNORM` bits and without `POLLOUT`, which `pollscan` clears, and the write end is writable when `PIPE_BUF` (512) bytes are free on Windows, or when the host kernel says so on Linux. `POLLOUT` on a read end throws: FreeBSD opens both ends for reading and writing and reports it writable, and host pipes are one-way. Windows pipes cannot be waited on, so while a pipe is polled `poll` checks it with `NtQueryInformationFile` and waits on the sockets in slices of 1 ms. A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket nor a pipe (files, stdio) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on.

A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket, a pipe, a file nor a directory (stdio, devices) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on.

Windows pipes cannot be waited on, so while a kqueue waits on a pipe it checks it with `NtQueryInformationFile` and waits on its sockets in slices of 1 ms; a wait with no pipe is not sliced. `EVFILT_READ` on the write end of a pipe throws: FreeBSD's `pipe` opens both ends for reading and writing ([`kern_pipe`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/sys_pipe.c#L422)), and host pipes are one-way. `EVFILT_WRITE` on a pipe and `NOTE_LOWAT` on a pipe, which `filt_piperead` ignores, throw too.
 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
 - [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.

Subject: [PATCH 0741/1000] feat(libkernel): poll the random device as
 randomdev_poll does

poll threw for /dev/random and /dev/urandom, which select already treats as ready. FreeBSD 11.4's randomdev_poll, once the device is seeded, narrows a request that has POLLIN or POLLRDNORM to those bits and returns any other request whole, POLLOUT and the band bits included. poll now answers that, and the test that relied on the random device throwing uses a kqueue descriptor, which poll still does not support.

 - [read, write and vector I/O](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on a guest socket use `recv` and `send` without flags; `sceKernelReadv` and `sceKernelWritev` gather or scatter through one socket operation, preserving stream short reads and datagram boundaries. The positioned `pread`, `pwrite`, `preadv` and `pwritev` forms, and their `sceKernel` forms, return `ESPIPE` for an open guest socket and `EBADF` for a closed one. `EPIPE` from a write raises the host's `SIGPIPE` on Linux unless the socket has `SO_NOSIGPIPE` set, and the guest cannot ignore it: `signal(SIGPIPE, SIG_IGN)` and `sigaction` record the disposition, as they do for every number from 1 to 128, but only the six signals with host equivalents (2, 4, 6, 8, 11 and 15) take effect on the host or are delivered, so the host `SIGPIPE` is not stopped; nothing is raised on Windows; a `write` longer than `INT_MAX` bytes is `EMSGSIZE` where the console sends it. AIO on a guest socket still goes to the host, which has no such descriptor
 - [Socket descriptor numbers](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel, libSceNet) - `socket`, `accept`, `socketpair`, `dup`, `sceNetSocket` and `sceNetAccept` take the lowest free number of the host descriptor table that files use, as FreeBSD 11.4 `fdalloc` takes the lowest free entry of the one process table (`kern_descrip.c`), so every number stays below `FD_SETSIZE` (1024) while fewer than 1024 descriptors are open. The number holds a zero-access `NUL` handle on Windows and a duplicate of the host socket on Linux, and the socket tables map it to the socket. The host table also holds the runtime's own files, so the numbers differ from the console's; the first number `socket` and `sceNetSocket` return on a console and its `getdtablesize` are not measured. Paths that bypass the socket tables see the placeholder: libc `fdopen` on a socket opens it, and libkernel `close` of a libSceNet socket releases the number but leaves the libSceNet socket open. Palworld (PPSA23126), The Mound (PPSA26223) and Dying Light 2 (PPSA02262) set socket bits in a 1024-bit `fd_set`
 - [fstat on a guest socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) fills the fields FreeBSD 11's soo_stat and pru_sense_null fill and zeroes the rest: S_IFSOCK, the read bits while the receive side is open or data is queued, the write bits while the send side is open, st_size and st_blksize. Only this process's shutdown closes a side here; a peer's shutdown, close or reset does not clear the bits as FreeBSD's socantrcvmore and socantsendmore do. st_size is the host's FIONREAD, which for a Linux datagram socket is the size of the next datagram where FreeBSD counts every queued byte, and st_blksize is the host's SO_SNDBUF, which Linux reports as twice the size that was set. A socketpair end reports st_dev and st_ino 0, where FreeBSD's uipc_sense reports NODEV and a per-socket number
-- [poll](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) waits on guest sockets and pipes, through `WSAPoll` on Windows and `poll` on Linux; the `pollfd` layout and flag values are FreeBSD's. A libSceNet socket joins the same host wait through the native socket libSceNet lends to libkernel. `WSAPoll` rejects `POLLPRI`, so on Windows a socket's `POLLPRI` is asked as `POLLRDBAND` and `POLLIN` as `POLLRDNORM`; Winsock reports urgent data until it is read with `MSG_OOB`, where FreeBSD 11.4's `sopoll_generic` stops once the normal stream passes the mark. Guest `send` and `recv` refuse `MSG_OOB` with `EOPNOTSUPP`, so urgent data can only come from an outside peer and Windows keeps reporting `POLLPRI` after the stream passes the mark. A pipe follows FreeBSD's `pipe_poll`: the read end is readable when data is buffered, either end reports `POLLHUP` once the other end is closed, with the requested `POLLIN` and `POLLRDNORM` bits and without `POLLOUT`, which `pollscan` clears, and the write end is writable when `PIPE_BUF` (512) bytes are free on Windows, or when the host kernel says so on Linux. `POLLOUT` on a read end throws: FreeBSD opens both ends for reading and writing and reports it writable, and host pipes are one-way. Windows pipes cannot be waited on, so while a pipe is polled `poll` checks it with `NtQueryInformationFile` and waits on the sockets in slices of 1 ms. A regular file, a directory or a file read from app0.zar is always ready for `POLLIN`, `POLLRDNORM` and `POLLOUT` and never for `POLLPRI`, `POLLRDBAND` or `POLLWRBAND`, as FreeBSD 11.4's [`vop_stdpoll`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/vfs_default.c#L563-L574) and `vop_nopoll` answer every event `poll` accepts; which of the two the console's filesystems use is not known, and they agree on these events. A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket, a pipe, a file nor a directory (stdio, devices) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on.

 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
 - [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.

Subject: [PATCH 0742/1000] test(agc): order the late interrupt's commit after
 queue 0 waits

The test relied on queue 0 reaching its idle wait before the draw
pipeline committed the end-of-pipe label. It now forces that order: a
first submission runs the dispatch and leaves its batch unreaped
(APS5_NO_OPPORTUNISTIC_REAP), queue 0 must be waiting, then the label
is submitted while the test holds the GPU mutex, so the pipeline commits
it only after queue 0 handed it over and waits again.

Subject: [PATCH 0743/1000] fix(libkernel): answer select on files and the
 random device as FreeBSD's poll routines do

selscan asks a descriptor once, with the flags of every set it is in (POLLRDNORM for the read set, POLLWRNORM for the write set, POLLRDBAND for the exception set, plus POLLHUP and POLLERR), and marks each set whose flags the answer shares. A seeded random device's randomdev_poll narrows a request with POLLRDNORM to that bit and returns any other request whole, so in the read set it is readable and in no other set, and otherwise it is in each write and exception set it was asked in; select reported it readable and writable together and never exceptional. A regular file or directory went to the host poll, which on Windows threw; vop_stdpoll makes it readable and writable and never exceptional, which select now answers in process on every host, as poll does.

Subject: [PATCH 0744/1000] feat(libkernel): poll descriptors 0 to 2 with the
 console model select uses

select takes descriptors 0 to 2 as a console title's terminal with no input: 0 is never readable and 1 and 2 are always writable. poll threw for them unless the host happened to attach a pipe, so the same title could select on its standard streams but not poll them. poll now gives the same answer, with POLLOUT, the one bit ttydev_poll reports for a writable terminal, for 1 and 2 and nothing for 0.

 - [read, write and vector I/O](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on a guest socket use `recv` and `send` without flags; `sceKernelReadv` and `sceKernelWritev` gather or scatter through one socket operation, preserving stream short reads and datagram boundaries. The positioned `pread`, `pwrite`, `preadv` and `pwritev` forms, and their `sceKernel` forms, return `ESPIPE` for an open guest socket and `EBADF` for a closed one. `EPIPE` from a write raises the host's `SIGPIPE` on Linux unless the socket has `SO_NOSIGPIPE` set, and the guest cannot ignore it: `signal(SIGPIPE, SIG_IGN)` and `sigaction` record the disposition, as they do for every number from 1 to 128, but only the six signals with host equivalents (2, 4, 6, 8, 11 and 15) take effect on the host or are delivered, so the host `SIGPIPE` is not stopped; nothing is raised on Windows; a `write` longer than `INT_MAX` bytes is `EMSGSIZE` where the console sends it. AIO on a guest socket still goes to the host, which has no such descriptor
 - [Socket descriptor numbers](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel, libSceNet) - `socket`, `accept`, `socketpair`, `dup`, `sceNetSocket` and `sceNetAccept` take the lowest free number of the host descriptor table that files use, as FreeBSD 11.4 `fdalloc` takes the lowest free entry of the one process table (`kern_descrip.c`), so every number stays below `FD_SETSIZE` (1024) while fewer than 1024 descriptors are open. The number holds a zero-access `NUL` handle on Windows and a duplicate of the host socket on Linux, and the socket tables map it to the socket. The host table also holds the runtime's own files, so the numbers differ from the console's; the first number `socket` and `sceNetSocket` return on a console and its `getdtablesize` are not measured. Paths that bypass the socket tables see the placeholder: libc `fdopen` on a socket opens it, and libkernel `close` of a libSceNet socket releases the number but leaves the libSceNet socket open. Palworld (PPSA23126), The Mound (PPSA26223) and Dying Light 2 (PPSA02262) set socket bits in a 1024-bit `fd_set`
 - [fstat on a guest socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) fills the fields FreeBSD 11's soo_stat and pru_sense_null fill and zeroes the rest: S_IFSOCK, the read bits while the receive side is open or data is queued, the write bits while the send side is open, st_size and st_blksize. Only this process's shutdown closes a side here; a peer's shutdown, close or reset does not clear the bits as FreeBSD's socantrcvmore and socantsendmore do. st_size is the host's FIONREAD, which for a Linux datagram socket is the size of the next datagram where FreeBSD counts every queued byte, and st_blksize is the host's SO_SNDBUF, which Linux reports as twice the size that was set. A socketpair end reports st_dev and st_ino 0, where FreeBSD's uipc_sense reports NODEV and a per-socket number
-- [poll](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) waits on guest sockets and pipes, through `WSAPoll` on Windows and `poll` on Linux; the `pollfd` layout and flag values are FreeBSD's. A libSceNet socket joins the same host wait through the native socket libSceNet lends to libkernel. `WSAPoll` rejects `POLLPRI`, so on Windows a socket's `POLLPRI` is asked as `POLLRDBAND` and `POLLIN` as `POLLRDNORM`; Winsock reports urgent data until it is read with `MSG_OOB`, where FreeBSD 11.4's `sopoll_generic` stops once the normal stream passes the mark. Guest `send` and `recv` refuse `MSG_OOB` with `EOPNOTSUPP`, so urgent data can only come from an outside peer and Windows keeps reporting `POLLPRI` after the stream passes the mark. A pipe follows FreeBSD's `pipe_poll`: the read end is readable when data is buffered, either end reports `POLLHUP` once the other end is closed, with the requested `POLLIN` and `POLLRDNORM` bits and without `POLLOUT`, which `pollscan` clears, and the write end is writable when `PIPE_BUF` (512) bytes are free on Windows, or when the host kernel says so on Linux. `POLLOUT` on a read end throws: FreeBSD opens both ends for reading and writing and reports it writable, and host pipes are one-way. Windows pipes cannot be waited on, so while a pipe is polled `poll` checks it with `NtQueryInformationFile` and waits on the sockets in slices of 1 ms. A regular file, a directory or a file read from app0.zar is always ready for `POLLIN`, `POLLRDNORM` and `POLLOUT` and never for `POLLPRI`, `POLLRDBAND` or `POLLWRBAND`, as FreeBSD 11.4's [`vop_stdpoll`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/vfs_default.c#L563-L574) and `vop_nopoll` answer every event `poll` accepts; which of the two the console's filesystems use is not known, and they agree on these events. `/dev/random` and `/dev/urandom` follow FreeBSD 11.4's [`randomdev_poll`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/dev/random/randomdev.c#L274-L285) for a seeded device: a request with `POLLIN` or `POLLRDNORM` gets only those bits back, and any other request gets every requested bit.

Open descriptors 0 to 2 follow the console model `select` uses: descriptor 0 never reports an event and descriptors 1 and 2 report `POLLOUT`, whatever the host attaches to them.

Windows pipes cannot be waited on, so while a kqueue waits on a pipe it checks it with `NtQueryInformationFile` and waits on its sockets in slices of 1 ms; a wait with no pipe is not sliced. `EVFILT_READ` on the write end of a pipe throws: FreeBSD's `pipe` opens both ends for reading and writing ([`kern_pipe`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/sys_pipe.c#L422)), and host pipes are one-way. `EVFILT_WRITE` on a pipe and `NOTE_LOWAT` on a pipe, which `filt_piperead` ignores, throw too.
 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
 - [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.

Subject: [PATCH 0745/1000] fix(libSceNet): set an option on a libkernel socket
 through sceNetSetsockopt

MXGP 26 (PPSA30839) opens TCP sockets with libkernel's socket() and
turns on TCP_NODELAY with sceNetSetsockopt. libSceNet only looked in its
own socket table, so the call failed with SCE_NET_ERROR_EBADF. On the
console both calls work on the same kernel sockets.

A descriptor libSceNet does not own but libkernel has open as a socket
now goes to libkernel's setsockopt(), which answers the options it
models. Anything else still fails with EBADF. The fallback runs after
g_mutex is released.

guest_sce_net sets SO_SNDBUF on a libkernel TCP socket through
sceNetSetsockopt, and checks that the call fails with EBADF once the
socket is closed.

Subject: [PATCH 0749/1000] fix: keep the Python tools and tests on Python 3.9

`Path.write_text(newline=...)` and `zip(strict=True)` were added in
Python 3.10. macOS ships 3.9.6 as /usr/bin/python3, the interpreter CMake
finds when no newer one is installed, so `prepare_release_notes` raised
TypeError when the release workflow wrote its notes and the
`pr_overlap_tools`, `release_package` and `linux_fixed_base` tests failed
on a stock macOS host. Writing the encoded text keeps the newline
translation off on every host, and the dynamic tag counts are compared
before the pairs are walked.

Subject: [PATCH 0750/1000] docs(relinker): record what Rosetta executes on an
 M5

The Rosetta conversion limits were measured on an M1 running macOS 15.3.1
and an M5 Max. A survey on an M5 running macOS 26.4 executes ANDN, RDRAND,
the rest of BMI1 and BMI2, LZCNT, PREFETCHW, CLFLUSHOPT, AVX, AVX2, FMA,
F16C and MOVBE while CPUID reports none of them, and raises an illegal
instruction for RDSEED, CLWB, RDPID, ADCX and ADOX.

 - In executables and guest modules with a `PT_SCE_DYNLIBDATA` segment, the [code analysis](../../../core/relinker/relinker/src/analysis/CodeInstructionCollector.cpp) of the Windows and macOS outputs follows code only from the end of `PT_INTERP` to the end of the PLT after the last function of the unwind table, the end the pipeline's scans above use; a guest module with PLT relocations and no PLT after its last unwind function fails as the executable does. Code after that PLT is not analyzed: a TLS access in it is not rewritten, an entry point or pointer into it is ignored, and a function symbol or init/fini array entry pointing into it fails the conversion.
 - A relocation against a dynamic symbol entry that is all zero, like the null symbol, takes the value 0 plus its addend, as the gABI defines for `STN_UNDEF` ([pipeline](../../../core/relinker/relinker/src/pipeline/RelinkerPipeline.cpp)). The Linux output imports such an entry as an unnamed weak symbol, which the host loader resolves to 0; the Windows and macOS outputs write the value into the slot ([relocation builder](../../../core/relinker/elfpatcher/src/windows/WindowsRelocationBuilder.cpp)). What the console's loader does with such an entry is not measured. OliSe Player (PPSA01153) has seven of them, and its code calls through those slots only when they are not 0 ([#4437](https://github.com/boykopovar/AnyPS5/issues/4437)).
 - The Linux placement of the `--to-intel` stubs in the [ELF patcher](../../../core/relinker/elfpatcher/src/linux/LinuxElfPatcher.cpp) is covered only by a synthetic test.
-- `--to-rosetta` lowers what Rosetta lacks on top of `--to-intel` ([matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp)). AVX2, FMA, BMI1/2, F16C and MOVBE were observed to execute on an M5 Max without being reported through CPUID; this is not a guarantee for other Rosetta hosts. ANDN and RDRAND fault on an M1 running macOS 15.3.1. ANDN is lowered, but RDRAND and other BMI instructions still depend on the host. RDSEED becomes RDRAND and CLWB a NOP. RDPID returns processor 0, because Rosetta's TSC_AUX is the constant 0xAAAAAAAB; the same value reaches RDTSCP's ECX, which is not converted. ADCX/ADOX fault under Rosetta and are not converted: compilers do not emit them, and code that checks CPUID sees no ADX. The conversions are covered by the converter tests. ANDN lowering is also executed by an x86-64 test build under Rosetta on the M1; the other conversions were originally checked on an M5 Max, outside this repository's CI.

 - `--to-intel` replaces the approximate legacy SSE and VEX.128 register forms of RSQRTPS/RCPPS and VRSQRTPS/VRCPPS with [correctly rounded](../../../core/relinker/codegen/src/x86/ReciprocalLowering.cpp) 1/sqrt(x) and 1/x, not with the AMD approximation: its tables are not public. Intel's approximation of 1/sqrt(1.0) is 0x3F7FF000, and two Newton-Raphson steps on it settle on 0.99999994 instead of 1.0; a renormalised identity quaternion then turns into a NaN axis in PPSA21564, which the console does not show. Refined results now reach the exact value; unrefined ones can still differ from the console in the low bits. Each site costs an out-of-line stub (two jumps, a spill below the red zone, SQRTPS/DIVPS). Legacy SSE forms preserve the destination's upper YMM bits; VEX forms clear them. The 256-bit, scalar and memory forms keep the native instruction, as does a site shorter than 5 bytes with no movable instruction after it for the jump (5 sites in PPSA21564, counted before a following RIP-relative instruction could move into the stub; not recounted).
 - `--trace-imports` ([entry stub](../../../core/relinker/elfpatcher/src/windows/WindowsEntryStubBuilder.cpp)) exists for Windows output only. Only imports bound through a PLT slot, or through a GOT slot whose symbol is a function, are traced; a function reached through any other relocation, or looked up at run time with `sceKernelDlsym`, is not, and neither are weak imports or the imports of modules loaded at run time

Subject: [PATCH 0751/1000] fix(libkernel): return EFAULT from clock_gettime
 for a null result pointer

clock_gettime threw invalid_argument when the result pointer was null,
before looking at the clock id. FreeBSD 11.4's sys_clock_gettime reads the
clock through kern_clock_gettime, which fails with EINVAL for an unknown
clock, and only then copies the result out, so a null pointer fails with
EFAULT.

Read the clock into a local value first, then fail with -1 and EFAULT when
the pointer is null. A clock that is not supported still throws before the
pointer is looked at. Test the null pointer for the supported clocks.

Subject: [PATCH 0752/1000] fix(libkernel): report EINVAL for getdirentries on
 a non-directory

sceKernelGetdirentries on a descriptor that is not a directory returned
ENOTDIR from the host getdents64 on Linux, and ENOTDIR for every descriptor
missing from the directory table on Windows, including invalid ones.
FreeBSD 11.4's kern_getdirentries returns EINVAL when the vnode is not a
directory.

Return EINVAL for a regular file on both hosts and EBADF for an invalid
descriptor on Windows. Test getdents and getdirentries on a regular file and
list the pipe case, which still fails with ESPIPE on Linux, in the library's
technical debt file.

 - [system](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) runs no command. It follows FreeBSD 11's `lib/libc/stdlib/system.c` for a sandbox without `/bin/sh`: a null command returns 1 unconditionally, as that version does, and any command returns the wait status of a child that could not exec the shell and called `_exit(127)` (`0x7f00`). Whether the console's application sandbox has no shell, and whether `vfork` succeeds there (FreeBSD returns -1 when it fails), is unverified
 - [sceKernelWriteThrottlingStatus](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) reports no write throttling: the host SSD has no write budget, so the first qword of the 32-byte status is set to `UINT32_MAX` and the rest is zeroed. PPSA17221 reads only that qword: it multiplies it by 64 KiB and compares the product with byte thresholds up to 0x4AF00000 to pick one of five tiers. When the call fails the title assumes 0x4B000001 bytes, which selects the same top tier as `UINT32_MAX`. What the value measures on hardware (a remaining budget or a rate) and the meaning of the other three qwords are unknown
 - [Windows directory descriptors](../../../core/libs/prx/libkernel/File/src/DirectoryDescriptor.cpp) (libkernel) take one snapshot of the directory, on the first `getdents`, `getdirentries` or non-zero `lseek` (`SEEK_SET` or `SEEK_CUR`), and keep it until it is discarded; `lseek` to offset 0 only discards the snapshot, and the next read lists the directory again, so every rewind costs O(entries) on the next read. `lseek` takes the offset as an entry index and `SEEK_CUR` with offset 0 only reports the index. `SEEK_END` throws, where the NUL descriptor used to return 0, because FreeBSD defines it relative to the directory size, which is not modelled. A negative result returns `EINVAL` and a `SEEK_CUR` offset that overflows returns `EOVERFLOW`, as FreeBSD `vn_seek` reports them. Names whose UTF-8 encoding exceeds the one-byte `d_namlen` limit are not representable in this guest directory-record layout: `getdents` returns `ENAMETOOLONG` without consuming the entry. Repeated calls therefore report the same error and entries after that name cannot be reached through this descriptor; FreeBSD's `getdents` behavior for host filenames that exceed its `MAXNAMLEN` is not verified. `getdirentries` still reports 0 through `basep` instead of the position of the block it read, so only 0 and values returned by `lseek` are valid offsets; FreeBSD offsets are filesystem cookies
+- [getdents and getdirentries](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) return `EINVAL` for a descriptor that is not a directory, as [`kern_getdirentries`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/vfs_syscalls.c) does for a vnode that is not `VDIR`. On Linux a host pipe or FIFO still fails with `ESPIPE`, from the `lseek` that reads the base offset before `getdents64`, where `getvnode` returns `EINVAL` for a non-vnode descriptor
 - [/dev/random and /dev/urandom](../../../core/libs/prx/libkernel/File/src/RandomDevice.cpp) (libkernel) opened for reading return a descriptor backed by the host null device whose reads are filled with host OS entropy (`getentropy`, `rand_s` on Windows); both paths behave the same, never block, and positioned reads ignore the offset (FreeBSD `random(4)`). Only the exact paths are recognised, `fstat`, `lseek` and `mmap` see the null device, and opening them for writing throws
 - [pthread_mutexattr_getpshared and pthread_mutexattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Mutex.cpp) (libkernel) store and report private or shared attributes, following FreeBSD 11 libthr [thr_mutexattr.c](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libthr/thread/thr_mutexattr.c). Invalid values return `EINVAL` without changing the attribute. Guest threads execute in one host process; sharing mutexes across processes is not modeled. Console behavior and invalid-attribute error precedence are unverified.
 - [pthread_attr_getinheritsched, pthread_attr_setinheritsched, pthread_attr_getscope, pthread_attr_setscope, pthread_attr_getstackaddr](../../../core/libs/prx/libkernel/Pthread/Posix/Attr.cpp) (libkernel) follow FreeBSD 11 libthr ([thr_attr.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_attr.c), [thr_create.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_create.c)), not measured on the console: the scope defaults to `PTHREAD_SCOPE_SYSTEM` (2), only it and `PTHREAD_SCOPE_PROCESS` (0) are accepted and other values return `EINVAL`, and an inherit value other than `PTHREAD_INHERIT_SCHED` (4) or `PTHREAD_EXPLICIT_SCHED` (0) returns `ENOTSUP`. `pthread_attr_getstackaddr` returns the configured stack address pointer (null by default). A null output of `pthread_attr_getinheritsched` throws, since libthr writes through it unchecked. A thread keeps the scope it was created with, taken from the creating thread under `PTHREAD_INHERIT_SCHED`, and `pthread_attr_get_np` and `scePthreadAttrGet` report it, but every guest thread is a host thread at system scope, so process scope changes nothing

 - [sceSaveDataDirNameSearch2](../../../core/libs/prx/libSceSaveData.native/Export.cpp) (libSceSaveData.native) runs the same search as `sceSaveDataDirNameSearch` with the same condition and result structures, as [SharpEmu](https://github.com/sharpemu/sharpemu/blob/main/src/SharpEmu.Libs/SaveData/SaveDataExports.cs) does, its only source; what distinguishes it on the console is unknown.
 - [sceSaveDataMount3](../../../core/libs/prx/libSceSaveData.native/Export.cpp) (libSceSaveData.native) - a failed mount (BUSY, EXISTS, NOT_FOUND, MOUNT_FULL) leaves the result as it was, as shadPS4 does; not checked on hardware. Animal Well (PPSA22520) depends on it: it checks for its save with a mount it never unmounts, then saves with a second mount of the same directory, ignores its BUSY and keeps using the first mount point for `sceSaveDataPrepare`, its file and `sceSaveDataUmount2`
 - [sceSaveDataMount3](../../../core/libs/prx/libSceSaveData.native/Export.cpp) (libSceSaveData.native) - an unterminated or empty directory name, `.`, `..`, or a name containing `/`, `\` or `:` returns `SAVE_DATA_ERROR_PARAMETER`, which the [SDK 12.000 reference](https://github.com/peterpuppy/bm/blob/3f9d1ba6b896a53080460c903f5c15af8affb80d/features/ps5/document/output/psn_12/System/Save_Data/SaveData-Reference/sce-save-data-mount3.md#L196-L204) lists for an invalid parameter, and leaves the result as it was, as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/569ec04d1a77127c601eed522ad5bba187173f9d/src/libs/libSaveData.cpp#L652-L658) does. The [SDK](https://github.com/peterpuppy/bm/blob/3f9d1ba6b896a53080460c903f5c15af8affb80d/features/ps5/document/output/psn_12/System/Save_Data/SaveData-Reference/sce-save-data-dir-name.md#L32-L36) lets an application use only letters, digits, `-`, `.` and `@` in a name, and KytyPS5 also accepts `_` ([`valid_path_component`](https://github.com/KytyPS5/KytyPS5/blob/569ec04d1a77127c601eed522ad5bba187173f9d/src/libs/libSaveData.cpp#L276-L287)); which other names the console's mount rejects is not checked on hardware
+- [sceSaveDataGetMountInfo, sceSaveDataGetParam](../../../core/libs/prx/libSceSaveData.native/Export.cpp) (libSceSaveData.native) - null pointer arguments return `SAVE_DATA_ERROR_PARAMETER` instead of throwing C++ exceptions; unmounted targets return `SAVE_DATA_ERROR_NOT_MOUNTED`, and parameter type or buffer size violations return `SAVE_DATA_ERROR_PARAMETER` after slot lookup

Subject: [PATCH 0757/1000] fix(build): run the CPU-side tests in an
 ANYPS5_ENABLE_ASAN build

Under -DANYPS5_ENABLE_ASAN=ON with ASAN_OPTIONS=detect_leaks=0, 14 of
the 849 tests outside the AGC driver, shader and VideoOut suites failed
on main for reasons that come from the ASan build itself, not from the
code they test:

- libc copies the main executable's file-backed writable pages before
  remapping them anonymously. In an instrumented test executable those
  pages hold ASan's redzones around globals, so the memcpy reported a
  global-buffer-overflow at load (patched_libraries,
  guest_memory_lifetime). The ASan build copies the pages word by word
  without instrumentation.
- Five tests check that a local variable is on the thread's stack.
  With detect_stack_use_after_return, which is on by default on Linux,
  instrumented locals live on ASan's fake stack. These tests now run
  with it off. guest_kernel_is_stack also bounded the worker stack by
  the application area without the ASan build's arena offset.
- The relinker module tests and loadexec_arguments load instrumented
  libraries into a Python process or a relinked guest, so the ASan
  runtime is not first in the initial library list. They now run with
  verify_asan_link_order=0. Preloading libasan instead put its
  __cxa_throw interceptor ahead of libc.prx's and broke the unwind of
  an exception that LoadExec throws and catches.
- guest_allocator_failures limits RLIMIT_DATA to 128 MiB and then
  commits 300 GiB. ASan maps 37.5 GiB of shadow for that commit, which
  the limit refuses, and aborts. The ASan build skips that section.
- fiber checks the address of a local against the fiber's context too,
  so it runs without fake stacks as well. Its CheckActiveContext then
  reads the fiber stack word by word above that local, through the
  redzones of the frames on that stack, and is no longer instrumented.
- agc_multisample_guest_access passed aligned_alloc a size that is not
  a multiple of the alignment, which C11 does not allow and ASan
  rejects. It now rounds the size up.

add_asan_test_options appends to ASAN_OPTIONS for one test in an ASan
build and does nothing otherwise.

Subject: [PATCH 0759/1000] fix(libkernel): return EPROTOTYPE for a socket type
 inet does not have

socket() returned EPROTONOSUPPORT for every socket type it does not create.
FreeBSD 11.4's socreate returns EPROTOTYPE when no protocol is found, the
protocol is 0 and the type is not 0, and EPROTONOSUPPORT when a protocol was
given. Its inet domain (in_proto.c) has SOCK_RAW entries in every kernel and
a SOCK_SEQPACKET entry only with SCTP, and no SOCK_RDM or other type.

Return EPROTOTYPE for a type the inet domain never has, such as SOCK_RDM,
with protocol 0. SOCK_RAW and SOCK_SEQPACKET keep EPROTONOSUPPORT, since
whether the console creates them is not known. Test the unknown types and
mismatched protocols for AF_INET and AF_INET6, and list the socket types and
families that are not created in the library's technical debt file.

Written with AI assistance (Claude).

 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
 - [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.
 - [connect to AF_UNSPEC](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) dissolves a datagram association as FreeBSD 11.4's `udp_disconnect()` does, which resets the local address to the wildcard address and keeps the port. On Linux a socket bound to an explicit port keeps its local address as well (`127.0.0.1:<port>` stays `127.0.0.1:<port>`), because a bound socket cannot be bound again; one bound to port 0 is bound again to the wildcard address with the port it had
+- [socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) creates only `SOCK_STREAM` and `SOCK_DGRAM` sockets in `AF_INET` and `AF_INET6`. A type that FreeBSD 11.4's inet domain has no protocol for in any configuration ([`in_proto.c`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/netinet/in_proto.c) has no `SOCK_RDM` entry and no unknown type) fails with `EPROTOTYPE` when the protocol is 0 and `EPROTONOSUPPORT` otherwise, as [`socreate`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c) does. `SOCK_RAW`, which `in_proto.c` always has (`socreate` creates it for a privileged process), and `SOCK_SEQPACKET`, which it has only in a kernel built with `SCTP`, fail with `EPROTONOSUPPORT`; whether the console allows either is not known. `SOCK_DGRAM` with `IPPROTO_UDPLITE` and `AF_UNIX` (`socketpair` supports it) fail with `EPROTONOSUPPORT` and `EAFNOSUPPORT` where FreeBSD creates the socket
 - [msync](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) follows FreeBSD 11's `kern_msync` and `vm_map_sync`, not measured on the console: the address is rounded down to the page, a range that wraps is `EINVAL`, as is `MS_ASYNC` with `MS_INVALIDATE`, and a range whose start or any page is not mapped (as `sceKernelVirtualQuery` reports it, reservations included) is `ENOMEM`; a page unmapped from inside a larger mapping still counts as mapped there, since `sceKernelVirtualQuery` keeps reporting the whole mapping. The guest has no file mappings, so a successful call writes nothing back. `MS_INVALIDATE` on a mapped range throws: FreeBSD returns `EBUSY` when the range holds `mlock`ed pages, and locked pages are not tracked
 - [madvise](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) accepts `MADV_PROTECT` (10) as a no-op hint without modifying process protection. FreeBSD 11's `kern_madvise` (`sys/vm/vm_mmap.c`) handles it before the address check, ignores the address and length, and calls `kern_procctl(..., PROC_SPROTECT, PPROT_SET)`, which requires `PRIV_VM_MADV_PROTECT` and fails with `EPERM` without it. Returning 0 unconditionally assumes the calling process is privileged. Console behaviour is unverified
 - [mincore](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) follows FreeBSD 11's `sys_mincore` (`sys/vm/vm_mmap.c`), not measured on the console: the address is rounded down to the page, length 0 returns 0, a null vector over a mapped range returns `EFAULT`, an overflowing range or any unmapped page in the range (as reported by `sceKernelVirtualQuery`) returns `ENOMEM`. For valid ranges, a page reports `MINCORE_INCORE` (0x1) when `sceKernelVirtualQuery` reports it committed and 0 when it is only reserved; actual residency, referenced and modified bits are not modelled. Length 0 returns 0 when the start page is mapped and `ENOMEM` otherwise, and the range and mapping checks come before the null vector `EFAULT`, as in `kern_mincore` Java 25 LAN / DNS (PPSA99869) imports it

 Games ask for the console's language with `sceSystemServiceParamGetInt` and show their text in it when they have it. It is English (United States) unless `ANYPS5_LANGUAGE` is set to another console language number: 0 Japanese, 1 English (United States), 2 French, 3 Spanish, 4 German, 5 Italian, 6 Dutch, 7 Portuguese (Portugal), 8 Russian, 9 Korean, 10 Chinese (Traditional), 11 Chinese (Simplified), 12 Finnish, 13 Swedish, 14 Danish, 15 Norwegian, 16 Polish, 17 Portuguese (Brazil), 18 English (United Kingdom), 19 Turkish, 20 Spanish (Latin America), 21 Arabic, 22 French (Canada), 23 Czech, 24 Hungarian, 25 Greek, 26 Romanian, 27 Thai, 28 Vietnamese, 29 Indonesian, 30 Ukrainian. For example, `ANYPS5_LANGUAGE=21` selects Arabic. An empty value is the same as an unset one; any other value stops the game at its first language query with an error that names the variable.
 
+### PlayGo dumps without metadata
+
+When a dump has neither `sce_sys/playgo-chunk.dat` nor `sce_sys/playgo-scenario.json`, AnyPS5 cannot tell which nonzero PlayGo chunk IDs exist. Requests for those IDs stop with an error by default. Set `APS5_PLAYGO_UNLISTED_CHUNKS` to choose an answer for that dump:
+
+| Value | Answer for an unlisted chunk ID | Observed title that needs it |
+|-------|---------------------------------|------------------------------|
+| `installed` | Report it as installed (`LOCAL_FAST`). | High on Life (PPSA15388) needs this to load its saves. |
+| `absent` | Return `SCE_PLAYGO_ERROR_BAD_CHUNK_ID`. | Sifu (PPSA03001) uses this result to end its chunk-ID search. |
+
+Leave the variable unset to keep the explicit error. Any other value also stops with an error. Dumps that include PlayGo metadata are unaffected. These title-specific results come from emulator runs and have not been verified against a console.
+
 ### GPU selection
 
 The game runs on the first Vulkan 1.1 device with graphics and compute queues and swapchain presentation, preferring a discrete GPU over an integrated one. Set `ANYPS5_GPU` to a part of a device name, compared without regard to case, to run on another device; the names are printed at start-up in the `Physical device candidate` lines. When no usable device contains the text, the start fails and the error lists the device names.

Subject: [PATCH 0765/1000] refactor(agc): keep the address-pass changes clear
 of open PRs' lines

The scan tests' includes now sit before <array>, where #6706 and #5859 add theirs after it, and the pass counter's address flag is set after the read-only check instead of next to the pass reads #6566 rewrites. No behaviour change.

Subject: [PATCH 0766/1000] perf(agc): replace the plane copies around a depth
 plane's UAV clear by a depth clear

A compute kernel that stores one colour to every texel of a storage image over a depth plane (a shadow atlas clear) copied
the whole plane depth image -> staging buffer -> mirror before the dispatch and mirror -> staging buffer -> depth image
after it, although the kernel reads nothing and writes every texel.

A dispatch of the 15-word 8x8x1 image clear kernel (direct, no partial last group) whose T# lies on a depth surface now
reads its colour from guest memory under the GPU mutex, the place the kernel reads it. When the dispatch covers the whole
plane, the plane is one layer of level 0, the colour is a value the plane's format holds exactly (0 or 1 for a 16-bit
unorm view, 0 or 0xffff for a 16-bit uint view, 0 or a normal float in (0, 1] for a 32-bit view) and nothing is waiting to
write the colour, the dispatch still writes the mirror but the copy-in is left out, and the copy-out becomes a clear of the
depth image to that value. The colour is read again when the copy-out is replaced; a changed value keeps the copy-out.
Every other dispatch, stencil planes and declined values keep both copies.

agc_driver_depth_clear_hle_tests runs the clear sequences with the clear taken and with the copies, and compares the depth
image texel by texel through the mirror, the guest memory and the depth tests.

Retired Vulkan images remain allocated until device teardown to preserve outstanding references. Partial unmaps keep the guard; partial allocation reuse and guest access to live multisampled data remain unsupported.
 - [Stencil reference export replay](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) on devices without `VK_EXT_shader_stencil_export` supports at most sixteen values proved from constant, select and phi exports, with an export proved on every kept path. It records instances, then their triangles, then the reference classes of each triangle. One pipeline filters fragments at shader termination against a dynamic push value before late stencil and depth tests. The [Vulkan stencil-reference replacement rule](https://docs.vulkan.org/refpages/latest/refpages/source/FragStencilRefEXT.html) discards bits above the attachment's stencil width; supported stencil attachments have eight bits. Numeric subgroup observations throw except bounded own-lane mask plumbing and group control with kept-lane and derivative-helper coverage proved. WQM inputs must exclude helper contributions, since [non-quad subgroup operations may treat helpers as inactive](https://docs.vulkan.org/glslext/latest/glslext/khr/GL_KHR_shader_subgroup.html). Readonly guarded SRT reads may report internal host faults; these draws wait and check faults before publishing results, and loops throw. Indirect draws, restart, strips, fans, tessellation, mesh, multisampling, early tests, ordered pixel execution, guest shader memory writes, other fault-producing memory access, clocks, primitive ID inputs, attachment feedback and pipeline face/channel splits throw. An exhausted stage push range throws. Equivalence to console ordering has not been measured on console hardware.

Depth rendering is not written back to those guest bytes; this admission rule does not prove allocation reuse or preserve a depth writer through an incompatible view. A 2D storage view, or a one-layer 2D array view of layer 0, of level 0 with the plane's extent and format (32-bit float or the 32-bit depth-bits layout for the depth plane, 16-bit unorm for D16, 8-bit uint for the stencil plane) is a storage image that is [filled](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) from the depth image before every use and, when the shader writes it, copied back after the work: a whole-plane copy through a staging buffer each way. A written view is also left pending like any other storage image, so the plane's content, drawn depth included, reaches guest memory on the next flush of that range. A 2D array view of more than one slice of the depth plane, or of a later slice, is a storage image over the slices from 0 to its last (`LayeredDepthStorage`); only the slices from its base slice to its last are copied: a slice that has a depth surface at the plane's address plus a whole depth slice per layer (`DepthSliceBytes`, as for the depth plane copies below) is copied from that surface before every use and back to it after the work, every bound slice each time, through a staging buffer; the other slices hold guest memory like any storage image. These images are kept per address, extent, slice count, base slice, format and tile mode until the device goes away, outside the storage cache's budget. Such a view needs a layer pitch equal to that slice size, and another view of the same memory (the 2D view of its first slice, a view from another base slice, or a sampled copy) is a separate image, copied in before and out after each use, so views that are written before a flush and share a slice do not merge: the later copy-out wins, so their results are not merged. A matching view still throws when it is a cube, a 2D array of more than one layer of the stencil plane or from a later slice, or another level, when the surface is multisampled, when it names the depth plane of a 16-bit depth with stencil surface the device stores in a wider format, and when it was written after another view of the same plane (another format, tile mode, address or dimension) replaced it, as two such views bound in one dispatch are. Stored depth values outside 0..1 are not clamped, and Vulkan leaves that copy undefined without `VK_EXT_depth_range_unrestricted`. `agc_driver_depth_storage_dispatch` pins these paths; none is measured on the console.

A dispatch of the 15-word 8x8x1 image clear kernel ([`MatchStorageImageClear`](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp): one colour read from the V# in `user[8..11]` stored to every texel of the T# in `user[0..7]`) that covers the whole plane and stores 0 or 1 through a 16-bit unorm view, 0 or 0xffff through a 16-bit uint view, or 0 or a normal float in (0, 1] through a 32-bit float or integer view leaves out the copy-in and replaces the copy-out by a clear of the depth image to that value; the dispatch still writes the storage image. The colour is read again when the copy-out is replaced, and a changed value keeps the copy-out. Indirect dispatches, partial last groups, dispatches that queue on the draw pipeline, other values and formats, a plane the kernel covers only partly and stencil planes keep both copies. A written view is also left pending like any other storage image, so the plane's content, drawn depth included, reaches guest memory on the next flush of that range.

 - [Collapsed color array views](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) preserve the selected slice in the XOR address equation when the view is represented as a shifted 2D surface. Native Vulkan coverage checks R_X draws, array reads, publication and re-upload for slices 1-3; Lost Soul Aside PPSA26358 validates the RGBA16F cube mip chain on Windows/NVIDIA. Other devices and console comparisons remain unverified. Full-array views retain their layer addressing.
 - A [depth surface](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) is retired when a color target or a written storage image it does not serve overlaps it, or when it is sampled through a view it cannot serve and guest memory over it was written since it was last bound; lookups then skip it, so sampling reads the memory like any texture. Bound again, it keeps its own depth instead of the bytes written over it. Without write watching, a view it cannot serve still throws. A retired surface also gives up its depth and stencil planes, so another surface sharing them no longer copies from it.
 - [Depth plane copies](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver): a depth plane sampled as a 2D array or a cube, or a D16 plane read as `R16_UINT`, is copied into an image of its own (`DepthPlaneCopy`), kept per base address, extent, format and slice count; a slice comes from the live depth surface when one is bound at the slice's address and from guest memory (detiled) otherwise. A draw or dispatch that binds the plane copies again only the slices that changed and records nothing when none did: a surface slice when its image or write serial differs from the one copied (the serial is bumped when the surface is created, when a draw binds it as its depth target, when a pending fast clear is applied and when a written storage view of the plane is copied back), a guest-memory slice when its bytes were written since they were last read (`GuestMemory::UnchangedSince`), a snapshot write overlaps them, or its address, size or tile mode changed. The surface of the latest depth draw is copied at every use until another depth target is bound, since that draw may still be recorded after the copy. A slice's address is the base plus a whole 64 KiB-block depth slice per layer (`DepthSliceBytes`), and the cube face order is the array order; both are inferred from the titles' use, not measured on hardware. A 2D-array T# whose `BASE_ARRAY` is past slice 0 reads slices `BASE_ARRAY` to `LAST_ARRAY` of the copy, which holds slices 0 to `LAST_ARRAY`, and a 2D binding of it reads slice `BASE_ARRAY`; that follows the colour 2D-array semantics and the titles that hit it (PPSA01556, PPSA03912), and was not measured on hardware for depth surfaces. Planes with mips, a cube or a 2D T# with a base slice other than 0, a `BASE_ARRAY` past `LAST_ARRAY`, a cube with other than 1 or 6 slices, and other views of the planes still throw, and so do these copies of a 16-bit plane with stencil that the device stores as D24 or D32 (16-bit depth with stencil, below).

Subject: [PATCH 0767/1000] test(agc): keep the pixel user data alive through
 its recompile

The fragment request of agc_driver_vertex_clip_cull_distances took its
user data from a temporary vector, so GuestContext::userData (a span)
pointed at freed memory by the time Recompile read it. The ASan build
reports a heap-use-after-free in materializeSnapshot; other builds
read whatever the freed block still holds. The vector is now a local
that outlives the request, like the vertex stage's.

Subject: [PATCH 0768/1000] test(libkernel): expect the FreeBSD errors in the
 Windows directory tests

guest_directory_close expected ENOTDIR from getdents on a descriptor number
reused by a regular file, and guest_directory_buffer expected ENOTDIR for
descriptor -1. kern_getdirentries returns EINVAL for a vnode that is not a
directory and getvnode returns EBADF for a descriptor that is not open, which
is what sceKernelGetdirentries now reports on Windows.

Subject: [PATCH 0774/1000] fix(libkernel): check for a directory with fstat
 before getdents on Linux

The Linux path mapped ENOTDIR from getdents64 to EINVAL, but a pipe or FIFO
still failed with ESPIPE from the lseek that reads the base offset first.
FreeBSD 11.4's kern_getdirentries returns EINVAL for any descriptor that is
not a directory vnode, pipes included, and EBADF for one that is not open.

Check the descriptor with fstat before the lseek: EBADF and other host
errors are passed through, and anything that is not a directory returns
EINVAL. The getdents64 error line is unchanged again, and the technical debt
entry is removed since no difference is left.

 - [system](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) runs no command. It follows FreeBSD 11's `lib/libc/stdlib/system.c` for a sandbox without `/bin/sh`: a null command returns 1 unconditionally, as that version does, and any command returns the wait status of a child that could not exec the shell and called `_exit(127)` (`0x7f00`). Whether the console's application sandbox has no shell, and whether `vfork` succeeds there (FreeBSD returns -1 when it fails), is unverified
 - [sceKernelWriteThrottlingStatus](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) reports no write throttling: the host SSD has no write budget, so the first qword of the 32-byte status is set to `UINT32_MAX` and the rest is zeroed. PPSA17221 reads only that qword: it multiplies it by 64 KiB and compares the product with byte thresholds up to 0x4AF00000 to pick one of five tiers. When the call fails the title assumes 0x4B000001 bytes, which selects the same top tier as `UINT32_MAX`. What the value measures on hardware (a remaining budget or a rate) and the meaning of the other three qwords are unknown
 - [Windows directory descriptors](../../../core/libs/prx/libkernel/File/src/DirectoryDescriptor.cpp) (libkernel) take one snapshot of the directory, on the first `getdents`, `getdirentries` or non-zero `lseek` (`SEEK_SET` or `SEEK_CUR`), and keep it until it is discarded; `lseek` to offset 0 only discards the snapshot, and the next read lists the directory again, so every rewind costs O(entries) on the next read. `lseek` takes the offset as an entry index and `SEEK_CUR` with offset 0 only reports the index. `SEEK_END` throws, where the NUL descriptor used to return 0, because FreeBSD defines it relative to the directory size, which is not modelled. A negative result returns `EINVAL` and a `SEEK_CUR` offset that overflows returns `EOVERFLOW`, as FreeBSD `vn_seek` reports them. Names whose UTF-8 encoding exceeds the one-byte `d_namlen` limit are not representable in this guest directory-record layout: `getdents` returns `ENAMETOOLONG` without consuming the entry. Repeated calls therefore report the same error and entries after that name cannot be reached through this descriptor; FreeBSD's `getdents` behavior for host filenames that exceed its `MAXNAMLEN` is not verified. `getdirentries` still reports 0 through `basep` instead of the position of the block it read, so only 0 and values returned by `lseek` are valid offsets; FreeBSD offsets are filesystem cookies
-- [getdents and getdirentries](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) return `EINVAL` for a descriptor that is not a directory, as [`kern_getdirentries`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/vfs_syscalls.c) does for a vnode that is not `VDIR`. On Linux a host pipe or FIFO still fails with `ESPIPE`, from the `lseek` that reads the base offset before `getdents64`, where `getvnode` returns `EINVAL` for a non-vnode descriptor
 - [/dev/random and /dev/urandom](../../../core/libs/prx/libkernel/File/src/RandomDevice.cpp) (libkernel) opened for reading return a descriptor backed by the host null device whose reads are filled with host OS entropy (`getentropy`, `rand_s` on Windows); both paths behave the same, never block, and positioned reads ignore the offset (FreeBSD `random(4)`). Only the exact paths are recognised, `fstat`, `lseek` and `mmap` see the null device, and opening them for writing throws
 - [pthread_mutexattr_getpshared and pthread_mutexattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Mutex.cpp) (libkernel) store and report private or shared attributes, following FreeBSD 11 libthr [thr_mutexattr.c](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libthr/thread/thr_mutexattr.c). Invalid values return `EINVAL` without changing the attribute. Guest threads execute in one host process; sharing mutexes across processes is not modeled. Console behavior and invalid-attribute error precedence are unverified.
 - [pthread_attr_getinheritsched, pthread_attr_setinheritsched, pthread_attr_getscope, pthread_attr_setscope, pthread_attr_getstackaddr](../../../core/libs/prx/libkernel/Pthread/Posix/Attr.cpp) (libkernel) follow FreeBSD 11 libthr ([thr_attr.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_attr.c), [thr_create.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_create.c)), not measured on the console: the scope defaults to `PTHREAD_SCOPE_SYSTEM` (2), only it and `PTHREAD_SCOPE_PROCESS` (0) are accepted and other values return `EINVAL`, and an inherit value other than `PTHREAD_INHERIT_SCHED` (4) or `PTHREAD_EXPLICIT_SCHED` (0) returns `ENOTSUP`. `pthread_attr_getstackaddr` returns the configured stack address pointer (null by default). A null output of `pthread_attr_getinheritsched` throws, since libthr writes through it unchecked. A thread keeps the scope it was created with, taken from the creating thread under `PTHREAD_INHERIT_SCHED`, and `pthread_attr_get_np` and `scePthreadAttrGet` report it, but every guest thread is a host thread at system scope, so process scope changes nothing

Subject: [PATCH 0775/1000] docs(libkernel): move the socket type debt entry
 away from other changes

The entry sat right after "connect to AF_UNSPEC", where the open #6884 adds
its own entry, so whichever merges second would conflict. Move it after the
mlockall entry, which no open pull request changes. The text is unchanged.

 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
 - [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.
 - [connect to AF_UNSPEC](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) dissolves a datagram association as FreeBSD 11.4's `udp_disconnect()` does, which resets the local address to the wildcard address and keeps the port. On Linux a socket bound to an explicit port keeps its local address as well (`127.0.0.1:<port>` stays `127.0.0.1:<port>`), because a bound socket cannot be bound again; one bound to port 0 is bound again to the wildcard address with the port it had
-- [socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) creates only `SOCK_STREAM` and `SOCK_DGRAM` sockets in `AF_INET` and `AF_INET6`. A type that FreeBSD 11.4's inet domain has no protocol for in any configuration ([`in_proto.c`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/netinet/in_proto.c) has no `SOCK_RDM` entry and no unknown type) fails with `EPROTOTYPE` when the protocol is 0 and `EPROTONOSUPPORT` otherwise, as [`socreate`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c) does. `SOCK_RAW`, which `in_proto.c` always has (`socreate` creates it for a privileged process), and `SOCK_SEQPACKET`, which it has only in a kernel built with `SCTP`, fail with `EPROTONOSUPPORT`; whether the console allows either is not known. `SOCK_DGRAM` with `IPPROTO_UDPLITE` and `AF_UNIX` (`socketpair` supports it) fail with `EPROTONOSUPPORT` and `EAFNOSUPPORT` where FreeBSD creates the socket
 - [msync](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) follows FreeBSD 11's `kern_msync` and `vm_map_sync`, not measured on the console: the address is rounded down to the page, a range that wraps is `EINVAL`, as is `MS_ASYNC` with `MS_INVALIDATE`, and a range whose start or any page is not mapped (as `sceKernelVirtualQuery` reports it, reservations included) is `ENOMEM`; a page unmapped from inside a larger mapping still counts as mapped there, since `sceKernelVirtualQuery` keeps reporting the whole mapping. The guest has no file mappings, so a successful call writes nothing back. `MS_INVALIDATE` on a mapped range throws: FreeBSD returns `EBUSY` when the range holds `mlock`ed pages, and locked pages are not tracked
 - [madvise](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) accepts `MADV_PROTECT` (10) as a no-op hint without modifying process protection. FreeBSD 11's `kern_madvise` (`sys/vm/vm_mmap.c`) handles it before the address check, ignores the address and length, and calls `kern_procctl(..., PROC_SPROTECT, PPROT_SET)`, which requires `PRIV_VM_MADV_PROTECT` and fails with `EPERM` without it. Returning 0 unconditionally assumes the calling process is privileged. Console behaviour is unverified
 - [mincore](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) follows FreeBSD 11's `sys_mincore` (`sys/vm/vm_mmap.c`), not measured on the console: the address is rounded down to the page, length 0 returns 0, a null vector over a mapped range returns `EFAULT`, an overflowing range or any unmapped page in the range (as reported by `sceKernelVirtualQuery`) returns `ENOMEM`. For valid ranges, a page reports `MINCORE_INCORE` (0x1) when `sceKernelVirtualQuery` reports it committed and 0 when it is only reserved; actual residency, referenced and modified bits are not modelled. Length 0 returns 0 when the start page is mapped and `ENOMEM` otherwise, and the range and mapping checks come before the null vector `EFAULT`, as in `kern_mincore` Java 25 LAN / DNS (PPSA99869) imports it
 - [mlockall, munlockall](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) - `mlockall` returns `EINVAL` for zero or unknown flags. Valid `MCL_CURRENT` throws because it would lock host stacks, heaps, modules and driver mappings along with guest memory; `MCL_FUTURE` throws because later mappings are not tracked for locking. FreeBSD 11.4's `sys_munlockall` (`sys/vm/vm_mmap.c`:1133-1165) checks `priv_check(td, PRIV_VM_MUNLOCK)` first (returning `EPERM` without it) and unwires the user map (`vm_map_unwire` over `vm_map_min`...`vm_map_max` with `VM_MAP_WIRE_HOLESOK`). Returning 0 unconditionally assumes the calling process is privileged. `munlockall` unlocks memory locked by `mlock` (`VirtualUnlock` on Windows, tolerating `ERROR_NOT_LOCKED` for pages never locked, and `munlockall` on Linux). On main, XPSemu (PPSA97358) fails to load at these imports (mlockall #4386, munlockall); their calls in QEMU `os-posix.c` execute only when `-overcommit mem-lock=on` is enabled. The call has not been observed in a run with this implementation.
+- [socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) creates only `SOCK_STREAM` and `SOCK_DGRAM` sockets in `AF_INET` and `AF_INET6`. A type that FreeBSD 11.4's inet domain has no protocol for in any configuration ([`in_proto.c`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/netinet/in_proto.c) has no `SOCK_RDM` entry and no unknown type) fails with `EPROTOTYPE` when the protocol is 0 and `EPROTONOSUPPORT` otherwise, as [`socreate`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c) does. `SOCK_RAW`, which `in_proto.c` always has (`socreate` creates it for a privileged process), and `SOCK_SEQPACKET`, which it has only in a kernel built with `SCTP`, fail with `EPROTONOSUPPORT`; whether the console allows either is not known. `SOCK_DGRAM` with `IPPROTO_UDPLITE` and `AF_UNIX` (`socketpair` supports it) fail with `EPROTONOSUPPORT` and `EAFNOSUPPORT` where FreeBSD creates the socket
 - [sigtimedwait](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) waits on a process-wide pending set instead of throwing: a signal raised while blocked stays pending and is taken by `sigwait`, `sigwaitinfo` or `sigtimedwait`, delivered to the handler when `_sigprocmask` unblocks it, or delivered by `pause`. The set covers all 128 signals and the lowest number that is pending and in the set is selected (FreeBSD specifies the lowest number only among real-time signals). Selection, `EAGAIN` on timeout, `EINVAL` for a `tv_nsec` outside 0 to 1000000000 while nothing is pending and `NULL` timeout blocking indefinitely follow FreeBSD's [sigtimedwait(2)](https://man.freebsd.org/cgi/man.cgi?query=sigtimedwait). `sigwait` returns 0 with the number in its output, as POSIX specifies, and `sigwaitinfo` and `sigtimedwait` return the number, as FreeBSD does. The guest `siginfo_t` follows FreeBSD 11's `sys/sys/siginfo.h`: 80 bytes, `si_signo` at 0, `si_code` at 8, `si_pid` at 12, `si_uid` at 16, `si_addr` at 24, `si_value` at 32 and `si_band` at 40; only `si_signo`, `si_code` (`SI_USER`) and `si_pid` (the guest pid) are written, `si_uid` stays 0 because no uid is modelled, and the console's layout is not verified. PPSA85300 imports `sigtimedwait` and fails to load without it; its only call site is VLC's `vlc_writev` ([filesystem.c](https://github.com/videolan/vlc/blob/6de05adcbaf2e8b85fe86aad4169393098628119/src/posix/filesystem.c#L243-L278)), which polls with a zero timeout to drain a `SIGPIPE` only after `writev` fails with `EPIPE`. The waits are not cancellation points and an unblocked caught signal does not interrupt them with `EINTR`, where FreeBSD's `sigwaitinfo` and `sigtimedwait` may return it. `SIGPIPE` has no host equivalent and is never raised by a host write here (see `read, write and vector I/O`), so VLC's drain finds nothing
 - [pause, sigsuspend, sigwait, sigwaitinfo](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) take the pending set of `sigtimedwait` instead of throwing. `pause` waits for a pending signal that is not blocked and whose disposition can be delivered, runs its handler on the calling thread and returns -1 with `EINTR`; an ignored signal is discarded and the wait continues, and it never returns for a signal whose handler cannot run. A signal whose registered handler has `SA_SIGINFO` still throws, and one whose disposition is the default action and that has no host equivalent (every signal except 2, 4, 6, 8, 11 and 15) is neither delivered nor discarded: it stays pending until a wait takes it, where FreeBSD runs the default action, which terminates the process for most of them. PPSA68091, PPSA99169, PPSA99420 and PPSA97358 import them and fail to load without them. PPSA68091 calls `pause` at one site (0x8F7266), in a loop that waits while a global holds another thread's `errno` address. PPSA99169 only stores the address of `pause` in a table of symbol addresses (0x30DB1). PPSA99420 calls `pause` at 0x3BD80F6 and 0x3C9E220, `sigwait` at 0x3C9E4C7 and `sigwaitinfo` at 0x3C9E588. PPSA97358 calls `sigwait` from QEMU's `sigwait_compat` thread ([compatfd.c](https://github.com/ZiZc3/XPSemu/blob/8eec07b4e31f66dce8e0b05c1ca1281af303e933/util/compatfd.c#L28-L53)), which `qemu_signal_init` ([main-loop.c](https://github.com/ZiZc3/XPSemu/blob/8eec07b4e31f66dce8e0b05c1ca1281af303e933/util/main-loop.c#L110-L147)) starts for `SIGIO`, `SIGALRM` and `SIGBUS` when the main loop is created, so it reaches the wait at start-up, and from the vCPU thread of the dummy accelerator ([dummy-cpus.c](https://github.com/ZiZc3/XPSemu/blob/8eec07b4e31f66dce8e0b05c1ca1281af303e933/accel/dummy-cpus.c#L48-L56)). `sigsuspend` swaps the process-wide mask of `_sigprocmask` for its argument, waits as `pause` does through the same helper, then restores the mask through `_sigprocmask`, and returns -1 with `EINTR`; a null set throws, as the console faults in libthr instead of returning `EFAULT`. All four words of the argument replace the mask and are restored afterwards, as in `_sigprocmask`. Java 25 LAN / DNS (PPSA99869, #5501) imports it and fails to load without it, after `sysctlnametomib`, `fegetenv` and `mincore`. None of the five waits is a cancellation point
 - [getsid](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) returns the calling process ID for pid 0 and the calling process, and `ESRCH` for other process IDs, assuming the single guest process is its own session leader. PPSA74126 imports it and fails to load without it

Subject: [PATCH 0779/1000] fix(agc): run the AGC GPU tests in an
 ANYPS5_ENABLE_ASAN build

After #7147 the CPU-side tests pass under AddressSanitizer, but 18 of
the 518 AGC driver and shader tests still failed there with
ASAN_OPTIONS=detect_leaks=0:

- Guest memory is raw memory, not a C++ object. ReadRawShader reads a
  shader's first 256 bytes before it knows the program's length, and
  ShaderMemory copies the 64-byte block around each word it is asked
  for. The tests place shaders and descriptors in small globals and
  locals, so those reads ran past them into ASan's redzones (13 tests,
  global- and stack-buffer-overflow). GuestMemory::CopyGuestBytes copies
  guest bytes with memcpy, and in an ASan build without
  instrumentation; Read and ShaderMemory's block load use it.
- The depth surface reuse checks in agc_driver_graphics use the made-up
  guest addresses 0x80000000 and 0x81000000, which lie in ASan's low
  shadow, so the HTILE read there looked mapped and read shadow memory.
  They now use 0x30000000 and 0x31000000.
- agc_driver_flat_store maps its watched blocks at 8 TiB and 32 TiB to
  cover page numbers on both sides of 16 TiB. 8 TiB is in ASan's high
  shadow; the ASan build uses 0x60000000 for the low one.
- agc_driver_gpu_map_on_fiber requires the fiber to use at most 8 KiB
  of its stack while its mapping is imported on a host thread. ASan's
  redzones make the same frames 9200 bytes; the ASan build allows
  16 KiB. It also requires a mapping on an ordinary thread to import on
  that thread's stack. Like MeasureStackReserve before #7115, the
  driver's inline-import check (Lifecycle.cpp) and onOwnLiveStack
  (GuestMemory.cpp) took the address of a local, which ASan's fake
  stack moves off the thread's stack, so the ASan build always imported
  on a host thread. Both now measure from __builtin_frame_address(0).

Subject: [PATCH 0784/1000] perf(recompiler): scan image-table key buffers in
 bulk

Narrowing a table column read its key buffer one key at a time, with a
page lookup and a single-word read per key; PPSA05684 scans about 20,000
keys per table snapshot. The scan now checks each page once and reads the
keys with the bulk reader, and maps a key to its record without dividing
when the multiplication cannot wrap.

Gameplay, image-table time per snapshot: about 6.5 ms before, 5 ms after.

AI-assisted: yes

Subject: [PATCH 0785/1000] fix(agc): patch relocated user words into stage
 data hits

A draw served through a relocated entry can also be a stage data hit on
the same stage. lookupDraw builds the stage data result first:
patchDataWords copies the variant's compiled result and refreshes the
flattened SRT data words. Only afterwards does draw apply the relocation's
shaderDataPatches, and only to matched[i]->compiled. programResults[i]
prefers stageData[i].compiled, so the stage was drawn with the push
constants and ShaderData user-word slots of the donor draw. Pointers the
shader reads at run time, which relocation had moved, kept the donor's
old values.

After applying a variant's shaderDataPatches, the stage data result of
the same stage is now rebuilt from the patched variant with the words the
lookup refreshed, so it carries both the new user words and the refreshed
data words. Variants without pending patches are skipped as before.

Found by reading the hit path: patchDataWords copies *variant.compiled
(VariantValidation.cpp) before applyShaderDataPatches replaces it
(DrawRelocate.cpp), and Draw.cpp selects the stage data copy when one
exists. Builds on Windows (MinGW GCC 15.2). A regression test that drives
a relocated stage data hit is still to be added.

Subject: [PATCH 0786/1000] test(agc): a relocated stage data hit draws with
 the moved user words

Adds MovedForwardedWordReachesStageDataHit to the draw cache relocation
test (agc_driver_draw_cache_relocation).

The fragment shader loads a pointer from the table its user words
s[0:1] point to, loads a float through that pointer and exports it as
red and alpha. It also exports bit 4 of user word s0 as green and blue,
so the compiled stage forwards s0 into its shader data while the table
read keeps s0 relocatable. The float is read through the loaded pointer,
not through a user word, so it is a stage data position and not part of
the relocation alias.

Six draws through tables at 32-byte aligned addresses (bit 4 clear) that
hold the same pointer teach the relocation and must reuse the cached
draw at least once; their pixels must be 255,0,0,255. The float is then
changed in place and one draw goes through a table at a 16-byte offset
(bit 4 set). It must be one lookup, one hit and one stage data hit: a
relocated entry whose fragment stage validates as EqualData. Every
written pixel must be 64,255,255,64: the refreshed data word and the
moved user word. Before 800ee777b the stage data copy kept the donor's
shader data, and the test fails with:

  AGC graphics: with graphics pipeline libraries: a relocated stage data
  hit did not draw with the moved user word: pixel 0 is 64,0,0,64,
  expected 64,255,255,64

DrawFrom takes the fragment shader as a parameter. The test binary
runs in 1.5 s. Tested on Windows 11 (MinGW GCC 15.2) on an NVIDIA
GeForce RTX 3050 Laptop GPU through Vulkan; agc_driver_draw_cache_reuse
and its _off, _verify and _inline variants still pass.

Subject: [PATCH 0787/1000] perf(recompiler): keep image-table indexes in
 per-thread scratch

Each image-table snapshot and resolution built node-based indexes and
dropped them at the end of the call: an unordered_map of distinct
descriptor words in TableSnapshotter, and in ResolveImageTables a map of
poison records, a set of expected poison codes, a map of bound elements
and an unordered_map of records per table. A table of N distinct entries
cost several allocations per entry on every dispatch.

The words, element and poison indexes are now open-addressing tables over
the vectors they index, and the per-table records a dense array by code.
Their slots live in per-thread scratch stamped per use, so a call reuses
the previous call's storage without clearing it; scratch above 2 MiB is
released after the call. Expected poison codes are a bit vector.

 - In executables and guest modules with a `PT_SCE_DYNLIBDATA` segment, the [code analysis](../../../core/relinker/relinker/src/analysis/CodeInstructionCollector.cpp) of the Windows and macOS outputs follows code only from the end of `PT_INTERP` to the end of the PLT after the last function of the unwind table, the end the pipeline's scans above use; a guest module with PLT relocations and no PLT after its last unwind function fails as the executable does. Code after that PLT is not analyzed: a TLS access in it is not rewritten, an entry point or pointer into it is ignored, and a function symbol or init/fini array entry pointing into it fails the conversion.
 - A relocation against a dynamic symbol entry that is all zero, like the null symbol, takes the value 0 plus its addend, as the gABI defines for `STN_UNDEF` ([pipeline](../../../core/relinker/relinker/src/pipeline/RelinkerPipeline.cpp)). The Linux output imports such an entry as an unnamed weak symbol, which the host loader resolves to 0; the Windows and macOS outputs write the value into the slot ([relocation builder](../../../core/relinker/elfpatcher/src/windows/WindowsRelocationBuilder.cpp)). What the console's loader does with such an entry is not measured. OliSe Player (PPSA01153) has seven of them, and its code calls through those slots only when they are not 0 ([#4437](https://github.com/boykopovar/AnyPS5/issues/4437)).
 - The Linux placement of the `--to-intel` stubs in the [ELF patcher](../../../core/relinker/elfpatcher/src/linux/LinuxElfPatcher.cpp) is covered only by a synthetic test.
-- `--to-rosetta` lowers what Rosetta lacks on top of `--to-intel` ([matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp)). AVX2, FMA, BMI1/2, F16C and MOVBE were observed to execute on an M5 Max without being reported through CPUID; this is not a guarantee for other Rosetta hosts. ANDN and RDRAND fault on an M1 running macOS 15.3.1 and execute on an M5 running macOS 26.4, where the rest of BMI1 and BMI2, LZCNT, PREFETCHW, CLFLUSHOPT, AVX, AVX2, FMA, F16C and MOVBE execute as well although CPUID leaf 7 reads zero and leaves 1 and 0x80000001 report none of them, and where RDSEED, CLWB, RDPID, ADCX and ADOX raise an illegal instruction. ANDN is lowered, but RDRAND and other BMI instructions still depend on the host. RDSEED becomes RDRAND and CLWB a NOP. RDPID returns processor 0, because Rosetta's TSC_AUX is the constant 0xAAAAAAAB; the same value reaches RDTSCP's ECX, which is not converted. ADCX/ADOX fault under Rosetta and are not converted: compilers do not emit them, and code that checks CPUID sees no ADX. The conversions are covered by the converter tests. ANDN lowering is also executed by an x86-64 test build under Rosetta on the M1; the other conversions were originally checked on an M5 Max, outside this repository's CI.

 - `--to-intel` replaces the approximate legacy SSE and VEX.128 register forms of RSQRTPS/RCPPS and VRSQRTPS/VRCPPS with [correctly rounded](../../../core/relinker/codegen/src/x86/ReciprocalLowering.cpp) 1/sqrt(x) and 1/x, not with the AMD approximation: its tables are not public. Intel's approximation of 1/sqrt(1.0) is 0x3F7FF000, and two Newton-Raphson steps on it settle on 0.99999994 instead of 1.0; a renormalised identity quaternion then turns into a NaN axis in PPSA21564, which the console does not show. Refined results now reach the exact value; unrefined ones can still differ from the console in the low bits. Each site costs an out-of-line stub (two jumps, a spill below the red zone, SQRTPS/DIVPS). Legacy SSE forms preserve the destination's upper YMM bits; VEX forms clear them. The 256-bit, scalar and memory forms keep the native instruction, as does a site shorter than 5 bytes with no movable instruction after it for the jump (5 sites in PPSA21564, counted before a following RIP-relative instruction could move into the stub; not recounted).
 - `--trace-imports` ([entry stub](../../../core/relinker/elfpatcher/src/windows/WindowsEntryStubBuilder.cpp)) exists for Windows output only. Only imports bound through a PLT slot, or through a GOT slot whose symbol is a function, are traced; a function reached through any other relocation, or looked up at run time with `sceKernelDlsym`, is not, and neither are weak imports or the imports of modules loaded at run time

Subject: [PATCH 0790/1000] feat(libSceAvPlayer): accept VP9 video and Opus
 audio streams

Sources whose streams are VP9 or Opus were dropped by IsStreamSupported, so
a WebM movie added with sceAvPlayerAddSource had no streams and the player
reported an error. The bundled FFmpeg already decodes both; their frames go
through the existing NV12 and PCM output paths.

Subject: [PATCH 0792/1000] test(agc): skip the multisampled target test
 without storage image multisampling

agc_driver_sample_multisample_target draws into a 4x target and reads
its samples back through a multisampled storage image. On a device
without shaderStorageImageMultisample, such as an Intel Arrow Lake iGPU
on ANV, the recompiler refuses that shader ('storage image multisampling
is unavailable on the target device') and the test failed. It now
skips there, as the recorder's storage multisample checks already do.

Subject: [PATCH 0795/1000] perf(shader): judge first-lane and constant reads
 by what they read

MayEvaluate took ReadFirstLane and ReadConst as evaluable without looking at
their sources, so plans kept conditions behind per-lane values.

 A cached shader keeps an `IrResourcePlan` (`ResourceMaterializer::ExtractPlan` in [`ResourceMaterializer.cpp`](../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp)) for as long as it is registered: a copy of the IR values its descriptor sources, SRT reads, uniform fill and control-flow conditions depend on, which every capture walks to read the shader's resources from guest memory.

A condition that depends on a vector register, or on an opcode the evaluator does not evaluate, takes both successors whatever the runtime holds, so the plan stores it as no condition and does not copy its operands. Such conditions are most of a shader's IR when the masked-lane code feeds its branches.

 ### Shader MODE register access

Subject: [PATCH 0796/1000] fix(shader): stop first-lane reads that reach
 themselves from recursing

MayEvaluate and the evaluator track the first-lane reads they are inside, so a read reached again through a loop-carried phi or a constant slot is not evaluable instead of recursing.

 A cached shader keeps an `IrResourcePlan` (`ResourceMaterializer::ExtractPlan` in [`ResourceMaterializer.cpp`](../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp)) for as long as it is registered: a copy of the IR values its descriptor sources, SRT reads, uniform fill and control-flow conditions depend on, which every capture walks to read the shader's resources from guest memory. The copy is sized to what the walk can use:

Subject: [PATCH 0804/1000] fix(libc): keep a drive-letter component of a guest
 path under its mount on Windows

A guest path is resolved by appending its components to the host root or
to a mount alias directory through std::filesystem::path. On Windows a
component such as "C:" that came first in the appended part was parsed as
a root name, so operator/ replaced the host directory instead of
appending: "/savedata0/C:/Windows/win.ini" and "/app0/../C:/Windows/win.ini"
resolved to "C:\Windows\win.ini", and "/C:/x" lost the component and
resolved to "<root>\x". A colon is an ordinary character in a FreeBSD
file name, so those names belong under the mount.

Guest paths are now split into component names and joined to the host
directory as text. Explicit native drive paths are still passed through.
On NTFS a name containing ":" still opens an alternate data stream; the
libc debt list now records it.

 - [The scanf family](../../../core/libs/prx/libc/src/Formatting.cpp) (libc), the `_s` forms included, on Linux throws for the 16-bit wide conversions (`%ls`, `%lc`, `%l[`, `%S`, `%C`): glibc would store a 32-bit `wchar_t` per character into the guest's 16-bit buffer. Windows hands `%ls`, `%lc` and `%l[` to the host, whose `wchar_t` is 16 bits
 - [The scanf family](../../../core/libs/prx/libc/include/WindowsScanning.hpp) (libc) on Windows returns 0, as C17 and FreeBSD do, when input fails after only suppressed conversions have completed (`sscanf("12", "%*d%d", &value)`). Linux hands the format to glibc, which returns `EOF` there. On Windows the host stops a `%x`, `%X`, `%i` or `%p` after the `x` of a `0x` that no hex digit follows (or that the width cuts off), and a float conversion (`%e`, `%f`, `%g`, `%a`) after the `e` of an exponent with no digits (`1e`), where C17 and FreeBSD stop before the `x` or the `e`
 - [Guest path resolution](../../../core/libs/prx/libc/src/General.cpp) falls back to ASCII case-insensitive component lookup, following [shadPS4's host filesystem](https://github.com/shadps4-emu/shadPS4/blob/945dbc3cc3eee80ac3e053b438502ed936fa6bb2/src/core/file_sys/backends/host_fs.cpp). PPSA03747 requests `Skyrim.INI`, `Data/Video` and lowercase archive/plugin names that differ from the dump's filenames. Exact host names take precedence; multiple fallback matches throw instead of selecting an arbitrary file. Existing parent names are resolved when creating a new file, and guest mount aliases use the same ASCII comparison. Results are not cached, so renames and newly created files remain visible. Unicode case folding and PS5 behaviour for case-colliding host entries are unverified; host roots are used as supplied. Explicit native Windows drive and UNC paths bypass guest parent-component validation.. A relinked module's `<name>.guest.prx` is matched the same way when the original module is not beside it: Borderlands 4 (PPSA01494) loads `/app0/prx/libRenoirCore.PS5.prx`, which it ships as `librenoircore.ps5.prx`
+- [Colons in guest names](../../../core/libs/prx/libc/src/General.cpp) (libc) - on Windows (NTFS) a guest name containing `:` is not a plain file name: `name:stream` opens or creates the alternate data stream `stream` of the file `name`. Creating `/savedata0/C:file` makes an empty file `C` whose stream `file` holds the data, and `stat` of `/savedata0/C` then reports a regular file. `mkdir` of a name containing `:`, such as `C:` or `dir:x`, fails with EINVAL. `name:stream` already behaved this way before drive-letter components were kept under their mount
 - [tzname](../../../core/libs/prx/libc/src/Time.cpp) (libc) points at the host's zone names, read at load and again by `tzset`: the abbreviations a `TZ` string gives (`EST5EDT` is `EST` and `EDT` on both hosts), but on Windows without `TZ` the CRT's full names such as `GMT Standard Time`, which ICU's [uprv_tzname](https://github.com/unicode-org/icu/blob/457157a92aa053e632cc7fcfd0e12f8a943b2d11/icu4c/source/common/putil.cpp#L1244-L1264) (ES-DE in PPSA99169) cannot map to a zone ID. A zone with no daylight-saving time has `tzname[1]` empty on Windows and equal to `tzname[0]` on Linux, where FreeBSD leaves three spaces. The console's names are not known
 - [Trailing slash on a mount alias](../../../core/libs/prx/libc/src/General.cpp) (libc) - on Windows a trailing slash after a file name under a mount alias such as `/savedata0` is still dropped, so `unlink`, `rename`, `open` and the other path calls act on the file where FreeBSD 11.4's `lookup()` fails with `ENOTDIR`; Linux and macOS pass the slash to the host, as for paths outside an alias
 - [localtime, mktime](../../../core/libs/prx/libc/src/Time.cpp) (libc) on Windows convert through the CRT's `localtime_s` and `mktime`, which accept about 1970 to January 3001 UTC and apply the CRT's daylight-saving rule. A time outside that range is converted a whole number of 400-year Gregorian cycles away, where the calendar repeats, so it gets the rule the CRT applies to that year and not the zone's historical one. `gmtime` converts every time whose year fits an `int` on both hosts.

Subject: [PATCH 0805/1000] ci(build): build the pull requests in the register
 context and write watch jobs

Both jobs checked out without a ref, so a dispatched build compiled and
tested main instead of the selected pull requests, although the gate
starts them because a pull request touched their files. They now check
out the gate's main commit and merge the pull requests with the same
step as the relinker, Linux and Windows jobs.

Subject: [PATCH 0807/1000] perf(shader): drop the result flush of a product
 behind its tiny-product check

A v_mul_f32 in a FLOAT_MODE that flushes f32 denormals emits the
nearest-even tininess check, the NaN result selection and then a
result flush. The check already turns every product that rounds below
2^-126 into a zero of its sign, so the flush can't change what it
keeps. DenormalFlushEliminator now proves that: a select arm guarded
by the tiny-product check of the same denormal-free factors, an arm a
select takes only when its own bits are NaN, and an and with a mask
that has no significand bits are denormal-free.

 - Comparison sampling of a color texture through an [image table](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) S# throws at the first dispatch or draw that binds it.
 - An [image table](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) key with no key domain whose `key * stride` wraps past 2^32 to an offset between records faults only when the build already expects a fault; otherwise the fault buffer is not read and it reads zeros.
 - [MaskedSelectEliminator](../../../core/shader/recompiler/Optimization/src/MaskedSelectEliminator.cpp) can discard inactive source lanes through `ReadFirstLane` only when its read mask implies the write mask and its result is unobserved outside the read mask. A loop-local read mask requires result uses in the same block without phi transport. The empty-EXEC lane-zero fallback follows AMD's [Vega ISA, section 12.8, V_READFIRSTLANE_B32, page 127](https://www.amd.com/content/dam/amd/en/documents/radeon-tech-docs/instruction-set-architectures/vega-shader-instruction-set-architecture.pdf) and the existing SPIR-V emitter. The optimization is covered by synthetic IR tests but has not been compared with console hardware; a proof that needs a read mask of a kind that is already being solved is refused.
+- [DenormalFlushEliminator](../../../core/shader/recompiler/Optimization/src/DenormalFlushEliminator.cpp) drops the result flush of a `v_mul_f32` or `v_mul_legacy_f32` product behind its nearest-even tininess check (see f32 denormals) when both factors are denormal-free: a product the check keeps is then zero, infinite, NaN or at least 2^-126 in magnitude, provided the driver rounds it as it rounds the check's multiply.
 - [Shader modules built at registration](../../../core/shader/recompiler/Recompiler.cpp) (shader recompiler): on devices with graphics pipeline libraries a vertex or pixel module reads buffer V# words, image modes, swizzles and mip ranges, depth-compare state, export mappings and vertex component selectors at run time instead of specializing on them per draw, so its libraries can be built when the shader is registered. A module that would exceed `SpirvTarget::registrationWordLimit` (200000 SPIR-V words) is emitted specialized as before: on RADV (Radeon 660M, Mesa 26.2.4) a sample of 60 Astro's Playroom pixel shaders compiled 1.9 to 2.2 times slower in registration form below 141k words and 3.8 to 5.7 times slower above 280k words (none in between), so the limit sits in that gap; it was not measured on other drivers. Texel-offset folding, the format word of a buffer accessed with the descriptor's format (`buffer_load_format_*`; as runtime values every format's decoder is compiled, which made CI's lavapipe JIT ten times slower) and the vertex attribute numeric class stay specialized, so shaders with the first two, and pixel shaders whose image needs a multisampled descriptor, get no registration result; these, and every draw whose fixed-function state differs from the prebuild's, still build their libraries at the draw. Compute and the other stages stay specialized: in registration form the `agc_driver_dword_pattern_fill` compute shader hung CI's lavapipe (Mesa 25.2.8) when built with `ANYPS5_ENABLE_SPIRV_TOOLS=ON`, not on RADV, and the cause was not found.
 - [SPIRV-Tools optimization](../../../core/shader/recompiler/SpirvBackend/src/SpirvOptimizer.cpp) skips CCP and Simplification for modules with storage-only 8- or 16-bit types because the pinned folder produces illegal narrow constants. This also disables unrelated constant folding; the restricted full pipeline mirrors the pinned performance recipe.
 - [SRT signed comparison](../../../core/shader/recompiler/Optimization/src/SrtWalker/SrtEvaluator.cpp) evaluates `SLessThan32` as signed 32-bit less-than, matching the existing SPIR-V backend and [SPIR-V `OpSLessThan`](https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#OpSLessThan). Signed boundary descriptor expressions are tested on the host; native RDNA2/PS5 execution and title behavior remain unverified.

Subject: [PATCH 0808/1000] test(libSceRudp): add GuestRudpContextLifecycle
 behavioral tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds tests for nine implemented libSceRudp functions that previously
lacked coverage:

- sceRudpActivate (returns 0 always)
- sceRudpEnableInternalIOThread (NOT_INITIALIZED before init, 0 after)
- sceRudpSetEventHandler (returns 0)
- sceRudpBind (NOT_INITIALIZED, INVALID_CONTEXT_ID, 0 on success)
- sceRudpSetOption (NOT_INITIALIZED, INVALID_CONTEXT_ID, 0 on success)
- sceRudpInitiate (NOT_INITIALIZED, INVALID_CONTEXT_ID, CONN_REFUSED)
- sceRudpGetContextStatus (NOT_INITIALIZED, INVALID_CONTEXT_ID, fills
  status with 0, null status allowed)
- sceRudpWrite (NOT_INITIALIZED, INVALID_CONTEXT_ID, CONN_RESET)
- sceRudpRead (NOT_INITIALIZED, INVALID_CONTEXT_ID, CONN_RESET)

Each assertion mirrors the exact implementation in Export.cpp. Error
codes and return values are the constants hardcoded in the source.
No console measurement needed — these are pure offline behaviors.

+- [sceHttpUriEscape](../../../core/libs/prx/libSceHttp/src/Uri.cpp) escapes every byte except the ASCII unreserved set in [RFC 3986 section 2.3](https://www.rfc-editor.org/rfc/rfc3986#section-2.3), independently of the host locale. Console behaviour for non-ASCII input remains unmeasured.

 - [sceHttpAbortWaitRequest, sceHttpWaitRequest](../../../core/libs/prx/libSceHttp/Export.cpp) (libSceHttp) - the abort takes only the epoll handle, as in [Orbital](https://github.com/AlexAltea/orbital/blob/master/tools/ida/db_types.json) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/Net/Http.cs); behaviour and error codes follow [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/main/src/core/libraries/network/http.cpp) (PS4), not confirmed on a PS5 title or hardware. An abort stays set: every later wait on the handle, a poll included, returns `SCE_HTTP_ERROR_ABORTED` (0x80431080) until the handle is destroyed. A wait woken by `sceHttpDestroyEpoll`, or by the `sceHttpTerm` that ends the last context, returns 0 events. The epoll calls return `BEFORE_INIT` (0x80431001) while no `sceHttpInit` context is alive and `INVALID_ID` (0x80431100) for an unknown context or handle, and `sceHttpTerm` returns the same errors instead of succeeding for any id. Handles are pointers, so a stale handle whose address a newer epoll reuses is taken as that epoll

Subject: [PATCH 0810/1000] fix(libc): reject null secure scan destinations

Prevent reached null conversion destinations from crashing sscanf_s and vsscanf_s. Return EOF before writes and retain earlier assignments. Add regression coverage through both guest ABI entry points.

AI-assisted: yes (OpenAI Codex). Windows WinLibs GCC 15.2 Release: production baseline crashes with the new regression; fixed shared libc passes guest_scan_count, guest_formatting, guest_wide_formatting and guest_strings (4/4). Conventions pass. Full all-target build was deliberately stopped after 83s with 3691 pending targets, not completed. No title or console run; constraint-handler invocation remains unimplemented as documented. No performance or coverage-percentage claim.

 ### Functional
 
+- [sscanf_s and vsscanf_s](../../../core/libs/prx/libc/src/Formatting.cpp) (libc) return `EOF` when a reached conversion has a null destination, stopping before further assignments, following C11 K.3.5.3.7 and K.3.5.3.14. Earlier assignments are retained. The constraint handler is not invoked, and console behaviour is unverified.
+
 - [__isfinitel](../../../core/libs/prx/libc/src/Math.cpp) - classifies the x87 80-bit exponent without narrowing to double or performing floating-point comparisons, following [FreeBSD msun](https://github.com/freebsd/freebsd-src/blob/main/lib/msun/src/s_isfinite.c). The signature and classification follow FreeBSD; console behaviour is unmeasured. Requires little-endian x87 long double stored in 16 bytes, as the existing guest long-double ABI does.
 
 - Windows direct-memory backing reserves a paging-file section. A [direct memory page](../../../core/libs/prx/libc/include/WindowsMappings.hpp) mapped at one guest address is private write-watched memory at that address and is not committed in the section; a page mapped at a second address moves its whole resident run into the section (committed there) and every address becomes a view of it, tracked by write protection. An unmapped resident page that is not all zeros is kept in a private reservation until it is mapped again. Committed section contents remain across unmap/remap and are released when the backing and its remaining views are destroyed. A host import alias over part of a resident run is refused. Linux retains its existing backing. Peak gameplay memory and Windows versions other than the tested host remain unverified.

Subject: [PATCH 0812/1000] feat(agc): render 5_6_5 UNORM color targets

Goosebumps Terror in Little Creek (PPSA27305) aborts in gameplay with
"unsupported color format 16 number type 0 component swap 2": it renders
into a COLOR_5_6_5 UNORM target. The target now renders into
R5G6B5_UNORM_PACK16. AMD keeps X in bits 0-4 and Z in bits 11-15, and
Mesa's ac_translate_colorswap programs SWAP_STD_REV for a surface with
red in bits 11-15, so with SWAP_STD_REV the exports are written as they
are and with SWAP_STD they are written with X and Z exchanged, as for
1_5_5_5. The alternate swaps and other number types keep throwing.

 - [Comp-to-single DCC keys](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DccMetadata.cpp) (libSceAgcDriver) - key 0x10 (`GFX9_DCC_CLEAR_SINGLE` in Mesa `ac_descriptors.h`) uniform over a surface makes every texel the element at the start of its 256-byte block, the top-left texel of the block where radv's `build_clear_dcc_comp_to_single_shader` stores the clear color. Sampled textures and storage images read that expansion (a storage image's first write stores the keys uncompressed, as under a clear code), and a CB DCC decompress pass stores it over the texels. A fast-clear eliminate over such keys throws, as a metadata pass over mixed keys does; color targets that render over such keys use their stored texels, and textures read mixed keys, and comp-to-single keys of a format whose element does not divide 256 bytes, as stored. "Uniform" is judged over the key bytes the driver reads, one per 256 surface bytes (see DCC key stores above), so a pipe-aligned surface whose keys differ past that range is expanded as if all were comp-to-single, as for the other clear codes. Not verified on hardware
 - [8_SRGB color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver) on a device that cannot attach and blend R8_SRGB render into an RGBA8_SRGB copy of the target, so the sRGB encode, decode and blend rounding are the device's; the console's are not measured.
 - [8_SRGB color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) on such a device throw unless they are single-mip 2D surfaces with a resident image; linear targets have none.
+- [5_6_5 color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) render into R5G6B5. The field holding X is in bits 0-4, Y in 5-10 and Z in 11-15, as for the other AMD formats; the component swap picks which export fills them, following `ac_translate_colorswap` in [Mesa 26.2.2 ac_formats.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/amd/common/ac_formats.c), which programs `SWAP_STD_REV` (2) for a surface with red in bits 11-15. With `SWAP_STD_REV` red goes to bits 11-15, R5G6B5's red, so the exports are written as they are; with `SWAP_STD` (0) red goes to bits 0-4 and the exports are written with X and Z exchanged, as for 1_5_5_5. The decoded format, component mapping and write mask are tested, and an execution test draws 32_ABGR exports into tiled and linear targets in both orders and compares every stored texel with that layout on the host device; the export direction is not measured on a PS5. Only UNORM with those two component orders is accepted; `SWAP_ALT` and `SWAP_ALT_REV` keep throwing. Destination alpha reads as 1, as Vulkan defines it for a format without alpha, which is not measured on the console. Constant blend colors with `SWAP_STD` go through the `0xc6` component-swap handling, which is not tested for this format. R5G6B5 has no entry in the DCC and multisample clear-encoding tables, so a CB DCC decompress or eliminate of DCC clear codes other than 0000 and a fast clear of a multisampled 5_6_5 target throw, as for 1_5_5_5. PPSA27305 renders into this format with `SWAP_STD_REV` (discussion #6434).
 - [1_5_5_5 color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) render into A1R5G5B5. AMD formats keep the first component in the least significant bits (X in bits 0-4, Y in 5-9, Z in 10-14, W in bit 15, as in the [fpPS4](https://github.com/red-prig/fpPS4) `kSurfaceFormat1_5_5_5` doc comment and as measured for textures in the packed 16-bit textures entry), while A1R5G5B5 keeps R in bits 10-14 and B in bits 0-4, so the pixel exports are written with X and Z exchanged, which makes the stored bits follow the guest layout. The decoded format, component mapping and write mask are tested, and an execution test draws 32_ABGR exports into tiled and linear targets and compares every stored texel with the guest layout on the host device; the export direction is not measured on a PS5. Only UNORM with the standard component swap is accepted. Constant blend colors go through the same component-swap handling as other targets with that export mapping (`0xc6`), which is not tested for this format. PPSA06699 renders into this format.
 - [COPY_DATA from the GPU clock](../../../core/libs/prx/libSceAgcDriver/Execution/src/Pm4.cpp) (libSceAgcDriver, `SRC_SEL` 9) writes the host steady clock in 10 ns ticks when the packet runs, the same counter as the `RELEASE_MEM` timestamp, not the console's GPU clock. The `COPY_DATA` cache policy fields are accepted and have no effect.
 - [COPY_DATA from a register](../../../core/libs/prx/libSceAgcDriver/Execution/src/Pm4.cpp) (libSceAgcDriver, `SRC_SEL` 0) copies the value the queue holds for a shader, context or user config register (`COUNT_SEL` two consecutive ones) and throws for a register with no value. A dispatch records `COMPUTE_DISPATCH_INITIATOR` and, for `DISPATCH_DIRECT`, `COMPUTE_DIM_X/Y/Z` in the shader registers; `DISPATCH_INDIRECT` clears the three counts. Neither the register values the CP writes nor the copy's ordering against in-flight dispatches have been measured on hardware.

Subject: [PATCH 0813/1000] perf(shader): fold a select nested in a select on
 the same condition

select(c, a, select(c, b, d)) is select(c, a, d), and
select(c, select(c, a, b), d) is select(c, a, d). The recompiler leaves
these behind when a register is written more than once under the same
lane mask and when the f32 NaN selection tests the same source twice,
and nothing folded them. The constant folder now takes the inner arm
the outer condition already decides, then folds a select whose arms
became equal.

Subject: [PATCH 0814/1000] fix(shader): declare the 64-bit integer type only
 for programs with BDA anchors

EmitBdaAnchors declared the u64 type before checking for anchors, so every
program got a 64-bit integer type, and programs without the Int64 capability
failed SPIR-V validation. It now returns before declaring anything when the
program has no anchors. A compute program without BDA reads is checked to
declare no 64-bit integer type and no Int64 capability.

 ## Driver thread priority
 
 Set `APS5_THREAD_PRIORITY=high` to raise the AGC driver's queue workers and the video output presenter above the title's threads. On Linux the threads get nice `APS5_THREAD_NICE` (default -10) through rtkit; on Windows they get `THREAD_PRIORITY_HIGHEST`. `APS5_THREAD_PRIORITY=rt` asks rtkit for real-time priority `APS5_THREAD_RT` (default 10, at most rtkit's `MaxRealtimePriority`) under rtkit's policy, `SCHED_RR` by default; on Windows it sets `THREAD_PRIORITY_TIME_CRITICAL`. rtkit only grants it when the process's hard `RLIMIT_RTTIME` is at most its `RTTimeUSecMax` (200000 us by default), so a hard limit above `APS5_THREAD_RTTIME_US` (default 200000, capped at `RTTimeUSecMax`) is lowered to it and the soft limit to at most half of it. The hard limit cannot be raised again and stays lowered for the whole process even if rtkit then refuses; see [technical debt](TechnicalDebt.md#functional). There is no fallback between the modes: when rtkit or `SetThreadPriority` refuses, a queue worker reports the refusal as a driver failure, which the next submission, wait or shutdown rethrows, and the presenter's start throws it. Each raised thread logs its priority once as `[thread-priority]`. The setting is `off` by default; a value other than `off`, `high` or `rt` is reported the same way as a refusal.

On Windows, `sceKernelClockGettime` monotonic clock ids are scaled too; on Linux they return the native host monotonic clock unchanged.

Subject: [PATCH 0819/1000] ci(build): save the Windows ccache from merge queue
 builds

Queue builds are workflow_dispatch runs on main and never saved their ccache,
so each one restored the last push build's entry and recompiled everything the
queued PRs and the merges since then touched (32 min vs 6 min warm). They now
save under their own prefix, restore it first and fall back to the push
entries; push builds still restore only push entries, so main never starts
from a tree that held unmerged PRs.

A reset clears a port's buffered data, and ports here buffer nothing (`sceVoiceReadFromOPort` returns 0 bytes and `sceVoiceWriteToIPort` throws), so it only checks that the library is initialized and the port exists, as RPCS3 does, and keeps the port's connections, volume and mute flag. An uninitialized library or an unknown port throws like the other port calls; the console's error codes are not measured. PPSA23566 imports it

Subject: [PATCH 0821/1000] feat(agc): import shared ranges whose backing
 offset is not 64 KiB aligned

A sparse import binds whole 64 KiB blocks, so a range whose memfd offset
is not a multiple of 64 KiB fell back to one UDMABUF_CREATE and, above
udmabuf's size limit, to copies. The sparse buffer now starts at the
block below the range: HostImport::lead holds that distance, the
import's device address points at the range itself, and every offset
into the import's buffer goes through HostImportOffset.

 - Windows host-pointer imports of the guest mapping itself are compared instead of write-watched, except writable imports of private `MEM_WRITE_WATCH` memory of 1 MiB or more when the import probe keeps the write watch and a settle queue exists (see Pages under an import window): a driver can mark imported pages dirty after the synchronous import window. Shared memory imported through a separate writable alias retains protection-based tracking on the guest views; driver access to the import alias does not disarm those views. [GuestMemory](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) excludes every overlapping 64 KiB tracker block while its backing is retained. A full block replaced by fresh private backing regains tracking and gets a new generation; protection changes, partial replacements and shared remappings do not restore it. Excluded blocks keep their write-watch marks as a hint only (`UntrackedHint`): a storage image or a sampled texture snapshot over them compares its bytes again after a mark in its range, a driver store, a mapping change or a recorded GPU write instead of at every collect epoch or lookup, and a mark the driver makes without a CPU store costs one comparison. This preserves CPU edits through byte comparisons but limits snapshot reuse on excluded blocks to draws of one collect epoch and disables unit shadows for them; restoring tracking on import retirement without replacing the backing remains unimplemented.
 - [Pages under an import window](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) (libSceAgcDriver) whose write protection was resolved while a host import that leaves its range watched was made are compared with the bytes they held before the import and count as stored over only when those differ. A CPU store of the bytes already there within the window cannot be told apart from an import that resolves the write protection without storing, as the NVIDIA driver (610.57.04) does for every imported page, so such a store does not win over pending results. Where host-pointer and dma-buf imports differ in whether they stay watched, a failed host-pointer import and the dma-buf import after it are two windows, and the pages the failed one resolved count as stored over. On Windows, the NVIDIA driver (617.42) marks every page of a host import of private `MEM_WRITE_WATCH` memory written, asynchronously, until the import's first GPU use completes. Such an import stays watched only after a 4-byte read of it on the settle queue has completed inside the window. Each one waits for that read, which keeps its window open for one round trip on the settle queue, so a same-value CPU store from another thread in that time counts as unchanged too. An import made where no settle queue exists, and an import of under 1 MiB, is compared instead: the settle blocks the importing thread, and a title that imports a 64 KiB buffer around every submission lost about 19 % of its frame rate to that wait (Dripl1x, #6060). Settling without blocking the importing thread (submit the read, keep the import compared until its fence signals, then switch it to the write watch) is not implemented.
 - [Settled dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a dma-buf import of 1 MiB or more is read by a 4-byte copy on the settle queue right after it is made (`settleImport`), so the kernel maps its pages for the GPU there and not in the first submission that uses it (about 2 s for a 3 GiB import on RADV). The import's buffer is shared with the settle queue's family. An import made at map time settles on the guest thread that maps the range, inside its map call, so that thread waits while the kernel maps the pages: 0.47 to 2.2 s for the 3 GiB range of Hades (PPSA03355) and 0.49 to 4.3 s for the 4.5 GiB range of ASTRO BOT (PPSA21567) on RADV. Both titles map these ranges at start-up; a title that maps large ranges during gameplay stalls its mapping thread for as long. An import made from a submission settles under the GPU mutex, so its frame still pays for it; a smaller import, and every import on a device with no settle queue (one without a copy-capable queue besides the main one), pays in its first submission. A range imported through a host pointer, as lavapipe imports shared memory, is not settled
-- [Sparse dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a shared-backed range larger than one 64 MiB udmabuf buffer is imported as one sparse buffer bound to the 64 MiB buffers, on a queue of its own when the device has a second family that binds sparse memory. The path is decided before anything is imported, and a failure after that throws. A range takes the single udmabuf import instead, which udmabuf's `size_limit_mb` refuses above 64 MiB by default so the range is copied, when its offset in the backing file is not a multiple of the buffer's sparse block size (64 KiB on RADV), when the sparse buffer does not accept every memory type a chunk import can have, when the backing file ends inside its last chunk, or when it is imported at map time on a device with no second family (the bind then needs the GPU mutex); the NVIDIA proprietary driver imports no dma-buf memory

 - [Unnormalized S# coordinates](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) - `FORCE_UNNORMALIZED` uses a Vulkan `unnormalizedCoordinates` sampler, so the S# LOD range, LOD bias and mip filter are not applied, which is exact only on a one-level view.
 - An [unnormalized S#](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) maps clamp mode 0 (repeat) on X and Y to clamp-to-edge as required by Vulkan unnormalized coordinates, and assigns the magnification filter when minification and magnification filters differ (since unnormalized coordinates sample at LOD 0). Anisotropy, TRUNC_COORD, MC_COORD_TRUNC and other clamp modes still throw. Secondary LOD bias (LOD_BIAS_SEC, bits [19:14]) is accepted and ignored, matching RDNA2 hardware measurements across explicit and implicit samples. High on Life (PPSA15388, #4736) uses secondary LOD bias and unnormalized coordinates with clamp mode 0 and differing min/mag filters during home base and city rendering.
 - [Background link-time-optimized relink of library pipelines](../../../core/libs/prx/libSceAgcDriver/Execution/include/PipelineLinkOptimization.hpp) (libSceAgcDriver) is skipped on every GPU under NVIDIA's proprietary Vulkan driver (`VK_DRIVER_ID_NVIDIA_PROPRIETARY`), so those pipelines keep their fast-linked form. The optimized link loses the device when bound on an RTX 3080 (Ampere, #2866) and an RTX 4060 (Ada, #3434); an RTX 5060 and an RTX 5080 (Blackwell) on the same driver do not, so the scope is wider than the evidence. No standard Vulkan query tells the architecture apart, and the driver version that fixes it is unknown. `APS5_NO_PIPELINE_LTO` disables the relink on every driver.

Subject: [PATCH 0822/1000] fix(agc): publish unit shadows at an import's lead

A unit shadow published its units into the import's buffer at the guest offset from the import's
base, without the import's lead, so a sparse import that starts below its range (HostImport::lead)
got the units lead bytes before their place. The shadow keeps the lead with the import's base and
buffer, and the shadow verify reads the guest bytes at the same place.

agc_driver_sparse_dma_buf_import publishes a unit shadow of its unaligned import and checks the
unit's guest bytes and the bytes around it; without the lead it fails there.

Subject: [PATCH 0823/1000] test(agc): check the unaligned import's lead only
 for a dma-buf import

A device that imports shared memory through host pointers, such as lavapipe, imports the unaligned range that way, and a host-pointer import has no lead.

Subject: [PATCH 0824/1000] feat(libkernel): implement
 pthread_condattr_setpshared

PSFlyCast (PPSA99247) imports pthread_condattr_setpshared (3BpP850hBT4)
from libkernel and fails to load without it:
"./app.elf: symbol lookup error: ./app.elf: undefined symbol: 3BpP850hBT4".

The attribute stores PTHREAD_PROCESS_PRIVATE (0) or
PTHREAD_PROCESS_SHARED (1); a null or uninitialized attribute and any
other value return EINVAL without changing it, following FreeBSD 11
libthr thr_condattr.c and pthread_mutexattr_setpshared here. Sharing
across processes is not modeled, as for mutexes.

 - [Windows directory descriptors](../../../core/libs/prx/libkernel/File/src/DirectoryDescriptor.cpp) (libkernel) take one snapshot of the directory, on the first `getdents`, `getdirentries` or non-zero `lseek` (`SEEK_SET` or `SEEK_CUR`), and keep it until it is discarded; `lseek` to offset 0 only discards the snapshot, and the next read lists the directory again, so every rewind costs O(entries) on the next read. `lseek` takes the offset as an entry index and `SEEK_CUR` with offset 0 only reports the index. `SEEK_END` throws, where the NUL descriptor used to return 0, because FreeBSD defines it relative to the directory size, which is not modelled. A negative result returns `EINVAL` and a `SEEK_CUR` offset that overflows returns `EOVERFLOW`, as FreeBSD `vn_seek` reports them. Names whose UTF-8 encoding exceeds the one-byte `d_namlen` limit are not representable in this guest directory-record layout: `getdents` returns `ENAMETOOLONG` without consuming the entry. Repeated calls therefore report the same error and entries after that name cannot be reached through this descriptor; FreeBSD's `getdents` behavior for host filenames that exceed its `MAXNAMLEN` is not verified. `getdirentries` still reports 0 through `basep` instead of the position of the block it read, so only 0 and values returned by `lseek` are valid offsets; FreeBSD offsets are filesystem cookies

Only the exact paths are recognised, `fstat`, `lseek` and `mmap` see the null device, and opening them for writing throws

Invalid values return `EINVAL` without changing the attribute. Guest threads execute in one host process; sharing mutexes across processes is not modeled. Console behavior and invalid-attribute error precedence are unverified.
+- [pthread_condattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Cond.cpp) (libkernel) stores a private or shared attribute, following FreeBSD 11 libthr [thr_condattr.c](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libthr/thread/thr_condattr.c): a null or uninitialized attribute and values other than `PTHREAD_PROCESS_PRIVATE` (0) and `PTHREAD_PROCESS_SHARED` (1) return `EINVAL` without changing it. Guest threads execute in one host process; sharing condition variables across processes is not modeled. PSFlyCast (PPSA99247) imports it and fails to load without it. Console behavior is unverified.
 - [pthread_attr_getinheritsched, pthread_attr_setinheritsched, pthread_attr_getscope, pthread_attr_setscope, pthread_attr_getstackaddr](../../../core/libs/prx/libkernel/Pthread/Posix/Attr.cpp) (libkernel) follow FreeBSD 11 libthr ([thr_attr.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_attr.c), [thr_create.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_create.c)), not measured on the console: the scope defaults to `PTHREAD_SCOPE_SYSTEM` (2), only it and `PTHREAD_SCOPE_PROCESS` (0) are accepted and other values return `EINVAL`, and an inherit value other than `PTHREAD_INHERIT_SCHED` (4) or `PTHREAD_EXPLICIT_SCHED` (0) returns `ENOTSUP`. `pthread_attr_getstackaddr` returns the configured stack address pointer (null by default). A null output of `pthread_attr_getinheritsched` throws, since libthr writes through it unchecked. A thread keeps the scope it was created with, taken from the creating thread under `PTHREAD_INHERIT_SCHED`, and `pthread_attr_get_np` and `scePthreadAttrGet` report it, but every guest thread is a host thread at system scope, so process scope changes nothing
 - [Shared memory](../../../core/libs/prx/libkernel/File/src/SharedMemory.cpp) (libkernel) on Linux implements anonymous and named objects, bounded descriptor writes and seeks, and `shm_unlink` with effective read/write permission checks from FreeBSD 11. Named paths up to 1023 bytes use `/anyps5-shm-` plus SHA-1; collisions are not detected, and the namespace is shared across processes in the host mount namespace. Named creation applies the guest umask without changing the host mask. Linux procfs and `/dev/shm` are required. Operations use an advisory directory lock; external host operations bypass it, unrelated objects serialize, and descriptor operations require two spare host descriptors and compare device/inode with the initial descriptor identity on both the pinned-object and ordinary-file fallback paths. [Guest mappings](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) support shared and private mappings of these descriptors through the allocation tracker and pin a duplicate descriptor during validation and mapping; mapping requires one spare host descriptor; file-backed mappings use the write-watch scan fallback because aliases and descriptor writes bypass per-mapping tracking. Named objects and file-backed mappings on Windows remain unsupported. Invalid non-null name pointers, console behaviour and title compatibility remain unverified.
 - [sceKernelAddReadEvent and sceKernelAddWriteEvent](../../../core/libs/prx/libkernel/Equeue/Equeue.cpp) (libkernel): a write event reports the socket's send buffer size (`SO_SNDBUF`) in `data`, not the free space left in it, as Windows has no query for that space. Only guest sockets are supported; other descriptors and a low watermark above 1 throw

Subject: [PATCH 0825/1000] ci(build): run test jobs only for the parts of
 build.yml a change touches

A change to build.yml ran the relinker, register-context and write-watch jobs whatever it touched. The patch's lines are now mapped to the job sections of the workflow at the head, and a test job runs only if its own section, the eligibility job or the shared part outside jobs changed; without a patch every job runs as before.

Subject: [PATCH 0826/1000] feat(libkernel): export nmount

Prospero Themes (PPSA90210) imports nmount (3YnXspQNyw8) from libkernel
and fails to load without it:
"./app.elf: symbol lookup error: ./app.elf: undefined symbol: 3YnXspQNyw8".

Mounting file systems is not supported, so it throws if called, like
execvp does for executable replacement. The title opens its theme
library without calling it.

Subject: [PATCH 0827/1000] fix(recompiler): give a dynamic-mip storage image a
 slot for every level

A dynamic-mip storage image reserved four mip slots, so a compute shader
whose T# spans more levels failed with "runtime storage image mip capacity
exceeded". PPSA01317 hits it on boot with a 512x512 surface of ten levels
and aborts. An RDNA T# addresses at most sixteen levels (4-bit BASE_LEVEL
and LAST_LEVEL), so a dynamic-mip image now reserves sixteen slots, and a
typed storage heap holds 64 elements so four such images still share one
class. Heap arrays keep their compact length. The runtime ABI goes to 14,
so existing shader caches are invalidated.

AI-assisted: yes

Subject: [PATCH 0828/1000] ci(build): run the relinker job's tests in parallel

The relinker job ran its 182 tests one at a time: 233 s on windows-latest, most of it Python tool tests. The full windows job already runs the same tests with --parallel 4.

 ### Unknown function info
 
 - [sceVoiceQoSSetConnectionAttribute](../../../core/libs/prx/libSceVoiceQoS/Export.cpp) (libSceVoiceQoS, NID `KCGOxg8iX7s`) is a throwing stub declared without parameters, like the other endpoint calls of the library: PPSA04159 fails to load without it and its signature is unknown. The name hashes to the imported NID (`tools/nid_names.py`)
-- [sceVoiceQoSInit](../../../core/libs/prx/libSceVoiceQoS/Export.cpp) (libSceVoiceQoS) - `0x804E0905` for a second initialization comes from [prosper](https://github.com/mattias800/prosper)'s reading of the module and was not measured: on a PS5 a valid call blocks inside a homebrew payload, so it never returns there. PPSA26344's two call sites (`0xE307BF`, `0x151C45D`) pass an allocated pointer, a 0x40000-byte block and app type 0x10000000; the app type and block are not used. `sceVoiceQoSCreateLocalEndpoint` takes four arguments (`int* id, userId, deviceInId, deviceOutId`) as declared in fpPS4 (`src/ps4_libscevoice.pas`, `ps4_sceVoiceQoSCreateLocalEndpoint`); no public reference exists for the other six signatures (`DeleteLocalEndpoint(id)`, `CreateRemoteEndpoint(int* id)`, `DeleteRemoteEndpoint(id)`, `Connect(int* id, local, remote)`, `Disconnect(connection)`, `SetLocalEndpointAttribute(id, attribute, value, size)`), which are assumed from function naming and call patterns and not confirmed on a PS5 title. Endpoints and connections are tracked by allocated id; duplicate connections and deleting an endpoint while referenced in a connection are permitted as the console is not known to reject them; local endpoint attributes are stored as given (including empty or non-positive sizes), as their ids and defaults are unknown; other endpoint and packet calls remain throwing stubs. The not-initialized error 0x804E0901 is assumed from the 0x804E09xx numbering, and unknown ids return `ARGUMENT_INVALID`. Aliens: Fireteam Elite (PPSA03393) uses all seven implemented calls on its first load path, starting with `sceVoiceQoSCreateLocalEndpoint` when it registers the local talker; it stops with `not implemented` when any of them throws

Subject: [PATCH 0836/1000] fix(libc): allocate the getifaddrs list on the
 application heap

FreeBSD's freeifaddrs is a plain free of the list, and Doom 3 BFG
(PPSA99313) releases the list with free. The list came from host malloc,
so the guest free stopped on an unregistered allocation; it now comes
from the application heap, and freeifaddrs returns it there.

Subject: [PATCH 0837/1000] fix(libSceNet): close a libkernel socket through
 sceNetSocketClose

MXGP 26 (PPSA30839) opens TCP sockets with libkernel's socket() and
later closes them with sceNetSocketClose. libSceNet only looked in its
own socket table, so every one of those closes failed with
SCE_NET_ERROR_EBADF and the host socket stayed open. On the console both
calls work on the same kernel sockets.

A descriptor libSceNet does not own but libkernel has open as a socket
is now closed through libkernel's close(). Anything else still fails
with EBADF. The fallback runs after g_mutex is released, because
libkernel's close() first asks libSceNet's socket closer, which takes it.

guest_sce_net closes a libkernel TCP socket with sceNetSocketClose,
checks that libkernel no longer has it open, and checks that a second
close fails with EBADF.

Subject: [PATCH 0839/1000] fix(shader): fold texel offsets into base-level
 unnormalized samples

An implicit-LOD or gradient sample with a texel offset through an
unnormalized S# was refused at bind time with "unnormalized guest sampler
is used by an implicit-LOD sample". PPSA01317 aborts on boot on such a
pixel image_sample_o. The base-level path already samples these through
OpImageSampleExplicitLod with LOD 0, which Vulkan allows for unnormalized
samplers, but it dropped the offset. It now adds the offset to the
coordinates in that branch, as the explicit-LOD offset fold does, so a
sampler whose uses also include offsets takes the base-level path. A
normalized S# keeps the offset operand.

AI-assisted: yes

+- [sceSaveDataCreateTransactionResource, sceSaveDataDeleteTransactionResource](../../../core/libs/prx/libSceSaveData.native/Export.cpp) (libSceSaveData.native) - transaction resources return synthetic positive identifiers and validate initialization state and non-zero parameters; transactional rollback semantics on host filesystem storage are unmodeled
 - [sceSaveDataPrepareForTransferring](../../../core/libs/prx/libSceSaveData.native/Export.cpp) (libSceSaveData.native, NID `RvID8BVeg+g`) - declared without parameters as a throwing stub; Minecraft (PPSA17221) imports it beside `sceSaveDataTransferringMountPs4` and `sceSaveDataDirNameSearchPs4` and fails to load without it. The name hashes to the NID but is not in aerolib; it was found by combining words from the libSceSaveData names in aerolib. Its arguments and behaviour are unknown.
 - [sceSaveDataTransferringMountPs4, sceSaveDataDirNameSearchPs4](../../../core/libs/prx/libSceSaveData.native/Export.cpp) (libSceSaveData.native) - arguments assumed to be those of `sceSaveDataTransferringMount` and `sceSaveDataDirNameSearch`: KytyPS5 binds both NIDs to the PS5 functions, and [prosper](https://github.com/mattias800/prosper) captured the same result layout on a title for the search. There is no PS4 save area, so the mount returns `NOT_FOUND` and the search reports zero hits
 - [sceSaveDataConvert](../../../core/libs/prx/libSceSaveData.native/Export.cpp) (libSceSaveData.native) - the parameter block (user id at `+0x00`, `SceSaveDataDirName` pointer at `+0x08`, 48 opaque bytes after it) is read from PPSA28416's single call, not confirmed by KytyPS5, shadPS4, fpPS4 or SharpProspero, which have no body for it. Host saves have no size limit, so an existing save returns `SCE_OK` without touching its files and no event is queued; what the console returns for a save that is mounted, already converted or needs no conversion is unknown. The directory name is validated as `sceSaveDataDelete` does

Subject: [PATCH 0841/1000] fix(main): unique directory for the large cache
 file test

Culprit: a03ccc6be (large cache files in chunks); failing run 39057904312.
The test used a fixed directory in the temp dir; the runners of one host
share it, so a concurrent run left a second entry behind.

PPSA26344's two call sites (`0xE307BF`, `0x151C45D`) pass an allocated pointer, a 0x40000-byte block and app type 0x10000000; the app type and block are not used. `sceVoiceQoSCreateLocalEndpoint` takes four arguments (`int* id, userId, deviceInId, deviceOutId`) as declared in fpPS4 (`src/ps4_libscevoice.pas`, `ps4_sceVoiceQoSCreateLocalEndpoint`); no public reference exists for the other seven signatures (`DeleteLocalEndpoint(id)`, `CreateRemoteEndpoint(int* id)`, `DeleteRemoteEndpoint(id)`, `Connect(int* id, local, remote)`, `Disconnect(connection)`, `SetLocalEndpointAttribute(id, attribute, value, size)`), which are assumed from function naming and call patterns and not confirmed on a PS5 title. Endpoints and connections are tracked by allocated id; duplicate connections and deleting an endpoint while referenced in a connection are permitted as the console is not known to reject them; local endpoint attributes are stored as given (including empty or non-positive sizes), as their ids and defaults are unknown; other endpoint and packet calls remain throwing stubs. The not-initialized error 0x804E0901 is assumed from the 0x804E09xx numbering, and unknown ids return `ARGUMENT_INVALID`.

Subject: [PATCH 0844/1000] fix(main): run the large cache file test alone with
 a longer hang limit

Windows run 39061030084: agc_shader_disk_cache_large_file wrote 2 GiB in 141 s next to 1399 parallel tests (limit 120 s), and conventions_function_bodies_shard_4 timed out at 30 s on the same loaded runner. The test is now RUN_SERIAL and its hang limit is 200 s (ctest timeout stays 240 s).

 - [snwprintf_s](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - follows C11 K.3.9.1.3 with `RSIZE_MAX` assumed to be `SIZE_MAX >> 1`. A runtime-constraint violation only returns a negative value: `set_constraint_handler_s` is not exported and the console's default handler is unknown. An invalid multibyte `%s` argument is copied byte by byte instead of being reported as an encoding error, as in `vswprintf`
 - [swprintf_s and vswprintf_s](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - follow C11 K.3.9.1.4 with `RSIZE_MAX` assumed to be `SIZE_MAX >> 1`: the complete output, including the terminating null, must fit in the buffer, otherwise it is a runtime-constraint violation that sets `buffer[0]` to zero and returns a negative value, and the buffer is not partially written. Argument and encoding checks match `snwprintf_s`
 - [strerror_s and strerrorlen_s](../../../core/libs/prx/libc/src/WideConversion.cpp) (libc) follow [C11 K.3.7.4.2 and K.3.7.4.3](https://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf), using the existing FreeBSD error messages and unknown-error formatting. Truncation writes an ellipsis when capacity exceeds 3; constraint failures leave the destination untouched and invoke the registered guest-ABI handler. The console's `RSIZE_MAX` (`SIZE_MAX >> 1` here), nonzero returns (`EINVAL` 22 for constraints, `ERANGE` 34 for truncation), handler arguments and default abort behavior are unverified. Messages remain in the C locale, and guest errno is preserved.
+- [getw and putw](../../../core/libs/prx/libc/src/BinaryWordIo.cpp) (libc) follow FreeBSD 11.4 [getw.c](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdio/getw.c) and [putw.c](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdio/putw.c): one 32-bit little-endian word, `getw` returns -1 for EOF or an error, and `putw` returns 0 on success or -1 on error while holding the stream lock. They use the existing host-backed streams, so buffering and error timing follow the host CRT. Null streams throw and closed streams return -1 with `EBADF`, as existing byte I/O does. Console behavior is unverified.
 - [vsnwprintf_s](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - `va_list` counterpart of `snwprintf_s` (C11 K.3.9.1.3): truncates to the buffer and returns the full length, with the same constraints and argument checks
 - [vsnprintf_s and vsscanf_s](../../../core/libs/prx/libc/src/Formatting.cpp) (libc) - `vsnprintf_s` forwards to `vsnprintf` semantics: the C11 K.3.7.1.5 runtime constraints (null buffer, `size == 0`, `%n`, null `%s`) are not checked, so `size == 0` returns the would-be length instead of a negative value, and no constraint handler is invoked. `vsscanf_s` returns the count of items converted before an undersized `%s`/`%c`/`%[` destination (0 when it is the first), not EOF. Neither is confirmed on a PS5 title
 - [strndup and strdup](../../../core/libs/prx/libc/src/AllocatingStrings.cpp) (libc) return null with `errno` set to `EINVAL` (22) when `source` is null, preventing a host segfault on invalid guest input. POSIX.1-2008 and FreeBSD 11.4 libc leave `strndup(NULL)` and `strdup(NULL)` undefined (faulting); exact console behavior on hardware is unverified.

Host saves have no size limit, so an existing save returns `SCE_OK` without touching its files and no event is queued; what the console returns for a save that is mounted, already converted or needs no conversion is unknown. The directory name is validated as `sceSaveDataDelete` does

Subject: [PATCH 0848/1000] fix(agc): draw rect lists in last provoking vertex
 mode

The generated rect-list control stage gave every corner of a rectangle the
flat inputs of its first vertex, so last mode was refused for rect lists.
BuildRectListShaders now also builds a control stage that takes them from
the rectangle's third vertex when the pixel shader has a flat input, and a
draw in last mode uses it.

 - [Dual-source blending](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) takes the MRT1 export as the second source of the MRT0 blend, as RADV and radeonsi program it; what the CB does with other export or target layouts is unknown, so they throw.
 - [Blending into reversed-order color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - 8_8_8_8 and 16_16_16_16 targets with `COMP_SWAP` 2 or 3 keep the exported alpha in their first channel and red or blue in their fourth, which Vulkan would blend with the color and the alpha equation respectively. The color block is taken to blend in shader export order and apply `COMP_SWAP` afterwards: the alpha equation and every source-alpha factor use the exported alpha, and the destination alpha is the first channel. This follows the `CB_TARGET_MASK` text of the AMD [SI](https://xorg.freedesktop.org/docs/AMD/old/SI_3D_registers.pdf) (p. 229) and [CIK](https://xorg.freedesktop.org/docs/AMD/old/CIK_3D_registers_v2.pdf) (p. 238) register references ("the order of components after blending and before COMP_SWAP is applied"). RADV builds `CB_BLENDn_CONTROL` without regard to the swap ([radv_pipeline_graphics.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/amd/vulkan/radv_pipeline_graphics.c#L650-L709)) and renders R4G4B4A4, B4G4R4A4, R5G5B5A1 and B5G5R5A1 with `SWAP_STD_REV` and `SWAP_ALT_REV` ([vk_format.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/vulkan/util/vk_format.c#L43-L48), [ac_formats.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/amd/common/ac_formats.c#L609-L624)). Mesa CI's Navi10 (gfx1010) CTS run ([job 112381553](https://gitlab.freedesktop.org/mesa/mesa/-/jobs/112381553), [112381554](https://gitlab.freedesktop.org/mesa/mesa/-/jobs/112381554)) passes all 400 `blend.format.<format>.states` cases of each of those formats, including separate alpha and destination-alpha factors. It is not measured on gfx1013 or on 8_8_8_8 and 16_16_16_16 targets. Factor pairs Vulkan applies per channel are used directly. Otherwise the pixel shader only copies values: it writes the exported alpha, each channel's own export or the constants 0 and 1 into a second color at location 0 index 1 (and 1 into a channel of the first color whose source factor is ONE, moving its export into the factor), and the blend forms every factor, `1 -` and product from those copies through `SRC1_COLOR`/`SRC1_ALPHA` factors. The blend unit therefore rounds them as it rounds a plain Vulkan blend of the same export; Vulkan does not require a second-source color to be converted like the first, but on an RTX 5080 and lavapipe every reversed-order case of the execution test is bit-identical to the same draw into a `SWAP_STD` target, which the test checks. Factor combinations that copies cannot express (for example `ONE_MINUS_SRC_ALPHA` in the alpha equation with `SRC_COLOR` in the color equation), sRGB, SNORM and integer targets, constant and second-source factors, destination-alpha and `SRC_ALPHA_SATURATE` factors in the color equation, different color and alpha operations, MIN or MAX with factors other than ONE, other color exports when the blend needs the second color, and devices without `dualSrcBlend` throw. Gran Turismo 7 (PPSA01317) blends `CB_BLEND0_CONTROL` 0x65010504 into such a target (#4782).
 - [DB_SHADER_CONTROL.CONSERVATIVE_Z_EXPORT](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderInputState.cpp) (libSceAgcDriver) becomes `DepthLess`/`DepthGreater`. For a pixel shader that breaks the promise, the host driver decides whether its interpolated Z is depth-tested before shading; what the console does then was not measured.

Subject: [PATCH 0849/1000] fix(libSceVideodec2): decode after a flush without
 a reset

sceVideodec2Decode threw when it followed sceVideodec2Flush without
sceVideodec2Reset. It now resets FFmpeg's drained decoder and decodes the
unit, keeping the pictures the flush has not returned yet.

 - [sceVideodec2CreateDecoder](../../../core/libs/prx/libSceVideodec2/Export.cpp) (libSceVideodec2) decodes HEVC (codec type 974921) and VP9 (2382845) through FFmpeg, besides H.264. The tags come from SharpProspero's `Videodec2CodecType` and EVO-PLAYER-PS5's `sce_videodec2.h`, which records them from hardware runs. HEVC input is converted from length-prefixed NAL units to Annex B as for H.264, and VP9 frames are passed through. Output is the same 8-bit NV12 for every codec; a decoder for HEVC Main10 or VP9 Profile 2 is created, but a frame deeper than 8 bits throws, since the console's 10-bit output layout is unknown, and `QueryDecoderMemoryInfo` reports the 8-bit frame size for it. `sceVideodec2GetPictureInfo` and `sceVideodec2GetAvcPictureInfo` throw for HEVC and VP9 pictures, which use other layouts (`SceVideodec2HevcPictureInfo`, `SceVideodec2Vp9PictureInfo`), and `sceVideodec2GetHevcPictureInfo` is not exported; `sceVideodec2GetVp9PictureInfo` has its own VP9 layout
 
 - [sceVideodec2GetVp9PictureInfo](../../../core/libs/prx/libSceVideodec2/Export.cpp) uses the 88-byte layout and two-pointer signature from [SharpProspero Videodec2.cs](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Video/Videodec2.cs). Frame metadata follows the [VP9 specification](https://storage.googleapis.com/downloads.webmproject.org/docs/vp9/vp9-bitstream-specification-v0.7-20170222-draft.pdf), sections 5.26 and 6.2: profile, key/intra-only flags, bit depth, color space/range, coded/render dimensions and superframe count are retained per emitted buffer. Level is 0 because the elementary stream does not signal a level; the console value is unverified. Null pointers, undersized structures and querying another codec throw; console error codes and support for other structure sizes are unknown. Existing NV12 output rejects pictures deeper than 8 bits. Superframes are submitted as individual coded frames to keep each output associated with its input metadata.
+- [sceVideodec2Decode after sceVideodec2Flush](../../../core/libs/prx/libSceVideodec2/Export.cpp) (libSceVideodec2) without `sceVideodec2Reset` restarts FFmpeg's decoder (`avcodec_flush_buffers`) and decodes the unit, where it threw before. TEKKEN DARK RESURRECTION (PPSA31371), which runs in Sony's PSP emulator, decodes after a flush without a reset (#7118), so the console accepts the call. Pictures the flush decoded but has not returned yet are returned before the new ones. What the console returns for them, and for a stream that continues across the flush without a new IDR picture, is not measured.
 - [sceVideodec2Decode](../../../core/libs/prx/libSceVideodec2/Export.cpp) (libSceVideodec2) and `sceVideodec2Flush` output the coded picture, with the chroma plane after its luma rows, as the console does for 1080p H.264 and HEVC streams coded at 1920x1088. An HEVC or VP9 picture whose size is not a multiple of 16, such as HEVC coded at 1920x1080, is output at that size; whether the console pads it is unverified. `sceVideodec2GetPictureInfo` reports no frame cropping

Subject: [PATCH 0850/1000] fix(agc): sample a multisampled target whose format
 differs only in red/blue order

Sampling a native multisampled color target through a texture of
another format was refused even when the two formats store the same
bytes in the other channel order. Rush 2 and Wave Race 64 render a
3840x2160 8x target as 8_8_8_8 with the alternate component swap
(B8G8R8A8_UNORM) and sample it through an 8_8_8_8 UNORM T#
(R8G8B8A8_UNORM), and stopped on "sampling multisampled color target
... (vk format 44) as a ... texture ... guest format 56 (vk 37) is not
implemented".

For the B8G8R8A8/R8G8B8A8 pairs of the same numeric type the texture is
now the target's own image with red and blue exchanged in its component
mapping, composed with the T#'s swizzle. Other format differences are
still refused.

 APS5_PLAYGO_UNLISTED_CHUNKS=absent

PPSA03490 (Demon Slayer: Kimetsu no Yaiba - The Hinokami Chronicles) has no playgo-* files in sce_sys. Its startup code asks scePlayGoGetLocus about chunk IDs 0, 1, 2, ... and stops when it gets SCE_PLAYGO_ERROR_BAD_CHUNK_ID, appending each ID to an array. With APS5_PLAYGO_UNLISTED_CHUNKS=installed no ID ever fails, the array keeps growing and startup aborts with 'Ran out of memory allocating 5565054976 bytes with alignment 65536'. With =absent the walk ends and the title gets past its logos to the menu and intro.

AI-assisted: yes. Written with AI assistance and reviewed by me.

Subject: [PATCH 0852/1000] fix(shader): run buffer atomics through a V# off a
 DWORD boundary

The binding plan refused every buffer atomic through a V# whose base is
not a multiple of 4. On RDNA2 such an atomic works when base + offset is
on a DWORD boundary and stops the dispatch otherwise, which the runtime
buffer atomic already does, so the refusal is dropped.

 - [64-bit LDS atomics](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (`ds_*_u64`, `ds_*_b64`, `ds_*_f64`) read and write the two dwords under a workgroup lock stored after the guest LDS, as LDS is a 32-bit array without 64-bit atomics. On RDNA2 (gfx1036) the LDS serialises a 32-bit atomic on a slot's high dword and a 64-bit atomic on that slot: 128 lanes of `ds_add_u32` and 128 lanes of `ds_add_u64` on one slot sum exactly. Only that pair was measured. Every 32-bit LDS atomic of a program that contains a 64-bit LDS atomic therefore takes the same lock, including a 32-bit `flat_atomic_*` whose address lands in the LDS aperture (a 64-bit one takes it already); the flat forms were not measured against a 64-bit atomic either (the other 32-bit LDS atomics, `ds_min/max`, `ds_cmpst`, the float forms, `ds_inc/dec`, `ds_mskor` and `ds_wrxchg`, are extrapolated from `ds_add_u32` and were not measured against a 64-bit atomic); a program without a 64-bit LDS atomic keeps its native 32-bit atomics. `ds_condxchg32_rtn_b64` is two `ds_mskor` halves, each under the lock but not atomic as a pair, so a 64-bit atomic between the two halves is not excluded. Sub-dword writes (`ds_write_b8`, `ds_write_b16` and their `_d16_hi` forms) and plain `ds_read_*`, `ds_write_*`, `ds_append_u32` and `ds_consume_u32` are not taken under the lock, so a plain access racing a 64-bit atomic on the same dwords can see or overwrite one half of it; whether the hardware orders them was not measured. The lock serialises the workgroup's LDS atomics of such a program; the throughput cost was not measured. `VK_KHR_workgroup_memory_explicit_layout` with `shaderSharedInt64Atomics` would make both widths native and is not used. A 64-bit atomic at an address that is 4-byte but not 8-byte aligned faults the wave on gfx1036, as on gfx1035.
 - [LDS float atomics](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (`ds_min/max/cmpst_f32`, `ds_min/max/cmpst_f64` and their `_rtn` forms) follow the hardware measured on RDNA2 (gfx1036) over 14 x 14 operand sets (zeros, ones, infinities, denormals, quiet and signalling NaNs of both signs and with payloads) in IEEE 0 and 1 with every value 0-3 of the type's denormal field: both operands are flushed to a signed zero when bit 0 of the field is clear (0 and 2; 1 and 3 keep them; the f32 field for the f32 forms, the f16/f64 field for the f64 forms; a shader without a known float mode flushes f32 and keeps f64), then a signalling-NaN data operand is stored quieted, else a signalling-NaN old value is stored quieted, else a quiet-NaN old value is replaced by the data, else a quiet-NaN data operand loses, else the ordered compare with -0 below +0 decides, and the flushed value is what is written, also when the old value wins. `cmpst` compares the flushed bits (both zeros equal, NaN never equal) and leaves memory unchanged when they differ. The returned value is always the old value as it was in memory. `IEEE_MODE` has no effect. The same bit rule serves the buffer float atomics (`AtomicFloatBits`). Not measured: a denormal or signalling-NaN `data1` of `cmpst` (stored as given). `ds_add_f32` and `ds_add_rtn_f32` follow RDNA1 (gfx1010, RX 5700 XT), measured with the [hardware oracle](../HW_ORACLE.md) template run through the Windows driver's comgr and HIP runtime over 1574 operand pairs (signed zeros, denormals, the smallest normals, infinities, quiet and signalling NaNs with payloads, the largest normals, random pairs near the denormal range and pairs that nearly cancel) in all 16 combinations of the f32 denormal field and the f32 round mode, and at IEEE 1 and DX10 clamp 0: both operands are flushed to a signed zero when bit 0 of the field is clear and the result when bit 1 is clear, the sum is rounded to nearest even whatever the round mode, a NaN data operand is stored quieted, else a NaN old value is stored quieted, `+inf + -inf` stores 0xffc00000, and `IEEE_MODE` and `DX10_CLAMP` have no effect. The sum is the host's `OpFAdd` between those flushes, so where the field keeps f32 denormals the result also depends on the host preserving them, which the module does not request. thuanquang measured the same rule on RDNA2 (gfx1031, RX 6700 XT) in #5492, with the same operand classes and 18 modes in wave32 and wave64; the PS5's gfx1013 is not measured.
 - [LDS in pixel, vertex-path and fetch programs](../../../core/shader/recompiler/SpirvBackend/src/SpirvAnalysis.cpp) (shader recompiler) - is an array private to each host invocation, in `Function` storage, as only compute and mesh programs get workgroup memory; on the console one LDS region is shared by the wave (RDNA 2 ISA sections 3.6.6 and 10.4), so a lane does not see another lane's LDS writes. Sub-dword writes (`ds_write_b8`, `ds_write_b16` and their `_d16_hi` forms), the 32-bit LDS atomics, `ds_append` and `ds_consume` load, update and store the invocation's own dword without an atomic, as Vulkan allows atomics only on `Uniform`, `Workgroup`, `Image`, `StorageBuffer`, `PhysicalStorageBuffer` and `TaskPayloadWorkgroupEXT` pointers (VUID-StandaloneSpirv-None-04686). `ds_append` and `ds_consume` update only the first active lane's copy and return its old value to every lane, so a second append after the first active lane changes, or a read of the counter by another lane, differs from the hardware. Not measured on hardware.
-- [V# bases off a DWORD boundary](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - raw accesses use the exact bytes and `s_buffer_load` reads `(base & ~3) + (offset & ~3)`, as measured on gfx1035 (Linux, alignment mode UNALIGNED; the console's mode is unknown). Formatted accesses off their element's alignment and atomics throw.
+- [V# bases off a DWORD boundary](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - raw accesses use the exact bytes and `s_buffer_load` reads `(base & ~3) + (offset & ~3)`, as measured on gfx1035 (Linux, alignment mode UNALIGNED; the console's mode is unknown). Formatted accesses off their element's alignment throw. Atomics use the byte address `base + offset`, base's low two bits included: measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) with `buffer_atomic_add`, `buffer_atomic_swap` and `buffer_atomic_cmpswap` and bases 0 to 3 bytes past a DWORD boundary with offsets 0 to 7, an address on a DWORD boundary updates that DWORD and returns its old value, and any other address stops the dispatch, which the recompiler reports as an unaligned access fault.
 - [32-bit bitfield masks](../../../core/shader/recompiler/Translation/src/IntegerInstructions.cpp) (`S_BFM_B32`, `V_BFM_B32`) use the truncating 32-bit shift specified by the [RDNA 1.0 ISA](https://www.amd.com/content/dam/amd/en/documents/radeon-tech-docs/instruction-set-architectures/rdna-shader-instruction-set-architecture.pdf), sections 12.1 (opcode 36) and 12.12 (opcode 867). Width and offset use their low five bits. This matches gfx1035 (Linux) for every width/offset pair, with and without upper operand bits set, and both leave SCC unchanged; not measured on the console.
 - [Vector buffer offsets that are not a multiple of 4](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - dword accesses count whole dwords from the V# base, where the hardware reads the exact bytes at base + offset.
 - [Raw `buffer_load_dwordx2`](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) is one 64-bit access on the hardware (with or without glc), so it never sees half of a `buffer_atomic_swap_x2`. Only a glc load that is 8-byte aligned and in bounds, in a program that has the 64-bit storage view (it uses 64-bit buffer atomics), is read with one 64-bit atomic load; every other dwordx2 load is two dword loads and can tear against a concurrent 64-bit write: loads without glc, and loads in a program without 64-bit buffer atomics while another shader writes the pair with `swap_x2`.

Subject: [PATCH 0854/1000] fix(libkernel): export sysarch so modules that
 import it load

The Wine port (PPSA99995) ships an ntdll module that imports sysarch
(b7uXQmnfB2s). libkernel did not export it, so loading stopped with
"undefined symbol: b7uXQmnfB2s" before the title ran.

Export sysarch as a stub that reports that it is not implemented: the
title loads and runs its launcher without calling it.

Subject: [PATCH 0855/1000] feat(libkernel): read and set the GS base through
 sysarch

sysarch's AMD64_GET_FSBASE, AMD64_GET_GSBASE and AMD64_SET_GSBASE now
follow FreeBSD 11's amd64 sysarch on Linux x86-64 through arch_prctl: the
GS base is the calling thread's, a base at or above VM_MAXUSER_ADDRESS
returns EINVAL and a null argument EFAULT. AMD64_SET_FSBASE, whose base
guest and host code share for their TLS, other operations and other hosts
still throw. Wine sets its TEB this way.

The GS base belongs to the calling thread, a base at or above `0x800000000000` (`VM_MAXUSER_ADDRESS`) returns `EINVAL`, and a null argument returns `EFAULT`. `AMD64_SET_FSBASE` throws, since guest and host code share the thread's FS base for their TLS.

The value on a PS5 follows the 16 KiB page size the rest of libkernel uses and is unmeasured. A write returns -1 with EPERM.

Subject: [PATCH 0857/1000] feat(agc): sample texture format 43 through a
 lossless B10G11R11 copy

Texture format 43 holds unsigned floats of 10 bits (R, bit 0), 11 bits
(G, bit 10) and 11 bits (B, bit 21). VK_FORMAT_B10G11R11_UFLOAT_PACK32
holds R11 at bit 0, G11 at bit 11 and B10 at bit 22, so storing the
guest R field in the Vulkan B field and the guest B field in the Vulkan R
field moves every texel without changing a bit of any component. A
sampled texture of format 43 is now uploaded that way (a repack pass over
the detiled words, TextureRepack.comp) and viewed with R and B swapped
back (TextureComponentChannel), so the shader samples it natively: point
and bilinear filtering, every mip level and LOD, and cube faces
work as for any other float texture. A texture whose results a storage
image still holds is copied from that image (vkCmdCopyImageToBuffer, the
repack pass, vkCmdCopyBufferToImage) and copied again whenever the
image changed, like the depth and block copies. The recompiler treats a
sampled format-43 image as a float image without conversion; storage
reads and writes keep the packed R32_UINT path, and a 3D texture whose
results are still in a storage image is flushed and uploaded instead.

PPSA01317 samples a mipmapped format-43 texture at a LOD other than 0
and a format-43 cube map during boot.

 - [Collapsed color array views](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) preserve the selected slice in the XOR address equation when the view is represented as a shifted 2D surface. Native Vulkan coverage checks R_X draws, array reads, publication and re-upload for slices 1-3; Lost Soul Aside PPSA26358 validates the RGBA16F cube mip chain on Windows/NVIDIA. Other devices and console comparisons remain unverified. Full-array views retain their layer addressing.
 - A [depth surface](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) is retired when a color target or a written storage image it does not serve overlaps it, or when it is sampled through a view it cannot serve and guest memory over it was written since it was last bound; lookups then skip it, so sampling reads the memory like any texture. Bound again, it keeps its own depth instead of the bytes written over it. Without write watching, a view it cannot serve still throws. A retired surface also gives up its depth and stencil planes, so another surface sharing them no longer copies from it.
 - [Depth plane copies](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver): a depth plane sampled as a 2D array or a cube, or a D16 plane read as `R16_UINT`, is copied into an image of its own (`DepthPlaneCopy`), kept per base address, extent, format and slice count; a slice comes from the live depth surface when one is bound at the slice's address and from guest memory (detiled) otherwise. A draw or dispatch that binds the plane copies again only the slices that changed and records nothing when none did: a surface slice when its image or write serial differs from the one copied (the serial is bumped when the surface is created, when a draw binds it as its depth target, when a pending fast clear is applied and when a written storage view of the plane is copied back), a guest-memory slice when its bytes were written since they were last read (`GuestMemory::UnchangedSince`), a snapshot write overlaps them, or its address, size or tile mode changed. The surface of the latest depth draw is copied at every use until another depth target is bound, since that draw may still be recorded after the copy. A slice's address is the base plus a whole 64 KiB-block depth slice per layer (`DepthSliceBytes`), and the cube face order is the array order; both are inferred from the titles' use, not measured on hardware. A 2D-array T# whose `BASE_ARRAY` is past slice 0 reads slices `BASE_ARRAY` to `LAST_ARRAY` of the copy, which holds slices 0 to `LAST_ARRAY`, and a 2D binding of it reads slice `BASE_ARRAY`; that follows the colour 2D-array semantics and the titles that hit it (PPSA01556, PPSA03912), and was not measured on hardware for depth surfaces. Planes with mips, a cube or a 2D T# with a base slice other than 0, a `BASE_ARRAY` past `LAST_ARRAY`, a cube with other than 1 or 6 slices, and other views of the planes still throw, and so do these copies of a 16-bit plane with stencil that the device stores as D24 or D32 (16-bit depth with stencil, below).
+- [Repacked format-43 copies](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver): a sampled texture of format 43 (10-bit R, 11-bit G and B unsigned floats from bit 0) is uploaded into a `B10G11R11_UFLOAT` image with its R and B fields swapped (`RepackTextureWord`) and viewed with R and B swapped back. A texture whose results a storage image still holds is copied from it again, whole, whenever the image changed (`RefreshDepthCopy`); a 3D one is flushed to guest memory and uploaded instead. Storage reads and writes of format 43 keep the packed `R32_UINT` path.
 - [SW_64KB_Z_X color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ColorTargetLayout.cpp) (libSceAgcDriver) use the texture equations and 64 KiB block geometry of `SW_64KB_Z_X`, whose addresses are checked against [AMD addrlib GFX10](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp) in the texture tiling tests. Any 256-byte pipe/bank XOR below the block size is accepted, as for `SW_64KB_R_X` targets and Z_X textures; which of those bits the console honours, and the render results, are not measured.
 - [SW_64KB_D_X color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ColorTargetLayout.cpp) (libSceAgcDriver) use the existing texture block/mip geometry and equations from [AMD addrlib GFX10 non-RB+](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp) for 16 pipes and 256-byte interleave. The address-reference tests use legal pipe/bank XOR bits for that configuration. Raw column bits outside the source configuration's pipe/bank mask 0xcf00 throw; their console meaning is unresolved. Console address equations and render results have not been measured.
 - [Per-face depth bias](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver): Vulkan has one depth bias per draw, so a draw that rasterizes both faces with different front and back bias (PA_SU_SC_MODE_CNTL, PA_SU_POLY_OFFSET_FRONT/BACK_*) is recorded twice, front faces with the back faces culled and then back faces with the front faces culled. The vertex stages run twice, so a vertex shader that writes memory writes twice, and all front faces land before all back faces instead of in primitive order, which differs only for blending or stencil updates that depend on the order.

Subject: [PATCH 0858/1000] fix(libkernel): accept an uninitialized attribute
 in scePthreadCondInit

scePthreadCondInit, and pthread_cond_init through it, threw when attr
pointed to a null attribute: a zeroed one that was never initialized or
one that scePthreadCondattrDestroy has set to null. FreeBSD 11.4 libthr
(thr_cond.c, cond_init) takes a null attribute as the default one and
creates a CLOCK_REALTIME condition variable. A PS5 (firmware 13.60)
takes a zeroed attribute as the default one in scePthreadMutexInit
(#4158). Take it as the default here too, as scePthreadMutexInit and
scePthreadCreate already do.

Subject: [PATCH 0859/1000] fix(relinker): decode near branches with an
 operand-size prefix as AMD does

66 E8, 66 E9 and 66 0F 80-8F without REX.W take a 16-bit displacement on
AMD processors, the console included. Every near relative branch with that
prefix truncates its target to 16 bits, so the decoder reports no branch
target for it and stubs refuse to move it.

 - [Guest import registries](../../../core/relinker/relinker/src/guest/GuestModuleBuilder.cpp) - declared host imports of bundled modules are recorded with their module name and relocation target, even when another guest module exports the same stripped NID. No-op relocations are omitted. Registries describe import bindings, not implementation correctness or runtime reachability.
 - Converted Windows main executables [omit `DYNAMIC_BASE`](../../../core/relinker/elfpatcher/src/windows/WindowsPeWriter.cpp) by default, not only with `--windows-fixed-base`: on the console the executable lies inside the 40-bit window that the title's own `sceLibcMspaceCreate` checks (#3043). Relocations are kept, so if `0x140000000` is taken Windows relocates the image, possibly above that window. Verified only on Windows 10.
 - [SDK memory-management syscall traps](../../../core/relinker/relinker/src/analysis/SyscallScanner.cpp) under `--trap-sdk-syscall-stubs` recognize three exact instruction sequences from [ps5-payload-dev SDK libc/mman.c](https://github.com/ps5-payload-dev/sdk/blob/12cf3dda40/libc/mman.c), observed in Nuvio Maxd 0.5.15 (PPSA99288): syscall 74 and the two syscall 477 paths, with their argument preparation and carry-flag error handling. Matching requires a decoded instruction boundary and the complete sequence inside the scanned code range. Other SDK/compiler output remains rejected. The matched syscall becomes `UD2`; this does not implement mmap or mprotect and a call still faults.
-- The [instruction decoder](../../../core/relinker/codegen/src/x86/X64InstructionDecoder.cpp) decodes a near CALL, JMP or Jcc with an operand-size prefix (`66`) as Intel does, with a 32-bit or 8-bit displacement and a 64-bit target. AMD processors, the console included, read a 16-bit displacement for `66 E8`, `66 E9` and `66 0F 80`-`8F` and truncate the target of every near branch with that prefix, rel8 forms included, to 16 bits. Compilers do not emit these forms; the relinker's length and target for them do not match the console.
+- The [instruction decoder](../../../core/relinker/codegen/src/x86/X64InstructionDecoder.cpp) reads a 16-bit displacement for `66 E8`, `66 E9` and `66 0F 80`-`8F` without REX.W, as AMD processors, the console included, do (binutils `objdump -M amd64`; REX.W selects the 32-bit form). AMD also truncates the target of every near relative branch with that prefix, rel8, LOOP and JRCXZ forms included, to 16 bits. Instruction metadata marks these branches as truncated and reports no branch target for them, and stubs refuse to move them. Compilers do not emit these forms.
 - `--to-intel` does not lower RDPRU/MCOMMIT; the [matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp) fails the relink instead.
 - The length-changing path of the [instruction rewriter](../../../core/relinker/codegen/src/x86/X64InstructionRewriter.cpp) is not used by the [converter](../../../core/relinker/codegen/src/Amd64OnlyConverter.cpp): it does not adjust data-to-code references (relocations, FDEs, jump tables) or segment sizes, so every substitution keeps the instruction length.
 - A `PT_SCE_RELRO` segment that no `PT_LOAD` covers, the PS4 layout, is [loaded](../../../core/relinker/relinker/src/parsing/ElfReader.cpp) as a read-write `PT_LOAD` and stays writable after relocation; FreeBSD rtld makes `PT_GNU_RELRO` read-only once relocation is done, and what the console does with `PT_SCE_RELRO` is not checked.

 - [Windows file timestamps](../../../core/libs/prx/libkernel/File/include/WindowsFileTime.hpp) use the host filesystem's timestamp range and resolution. `utimes`, `futimes`, and `lutimes` reject timestamps outside nonnegative signed 64-bit Windows file-time ticks with `EINVAL`, including exactly 1601-01-01 00:00:00 UTC, whose zero value means "leave unchanged" to `SetFileTime`. Guest directory descriptors still resolve through their recorded path. Filesystems with coarser timestamp resolution cannot retain every guest microsecond
 - [EVFILT_VNODE on macOS](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) (libkernel) registers `EVFILT_VNODE` on a duplicate of the descriptor in a host kqueue, whose notes have FreeBSD's values, and drops the `NOTE_LINK` that XNU adds to `NOTE_DELETE` when the watched file or directory is removed, since FreeBSD's `vop_remove_post` and `vop_rmdir_post` report `NOTE_DELETE` alone. As on Windows, a directory registered with `NOTE_EXTEND` is accepted but never receives it: XNU reports a move between directories as `NOTE_WRITE` alone, with `NOTE_LINK` for a subdirectory
 - [Windows file identity](../../../core/libs/prx/libkernel/File/src/NativeStat.cpp) (libkernel) - `stat` and `fstat` report the volume serial number as `st_dev` and the 64-bit file index folded into the guest's 32-bit `st_ino` (never 0), so two different files can in principle share an `st_ino`; the fold is not taken from a reference. `st_nlink` is clamped to 65535, the width of the guest field. The call keeps the `_wstat64` values when `GetFileInformationByHandle` fails
-- [lstat of a Windows symbolic link](../../../core/libs/prx/libkernel/File/src/NativeStat.cpp) (libkernel) reports a link whose target is relative, as `symlink` creates them, with the link's own times, `st_dev` and `st_ino`, mode `S_IFLNK | 0777` and the length of the target `readlink` returns as `st_size`. FreeBSD gives a new link `0777` less the creating process's umask, which the host does not keep, so the permission bits are not the console's. A link with an absolute target, a junction and any other reparse point throw, as for `readlink`

FreeBSD gives a new link `0777` less the creating process's umask, which the host does not keep, so the permission bits are not the console's. A directory junction is reported the same way, using its print name, or its substitute name when the print name is empty, without a `\??\` or `\\?\` prefix. A link with an absolute target and any other reparse point throw, as for `readlink`
 - [setitimer](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) follows FreeBSD's `sys_setitimer` and `kern_setitimer`: `EINVAL` for timers other than `ITIMER_REAL`, `ITIMER_VIRTUAL` and `ITIMER_PROF`, and for a value, or the interval of a non-zero value, with a negative field, `tv_usec` of 1000000 or more, or more than `INT32_MAX / 2` seconds; a null value reads the timer as `getitimer` does, with `EFAULT` when the output is null too. `ITIMER_REAL` shares the timer thread of `alarm`, which clears its interval: a zero value disarms it, the previous value is returned, and each expiry re-arms it by `it_interval`. An expiry delivers nothing: with `SIG_IGN` it is dropped, with the default disposition the process exits with status 142, and with a handler, or with `SIGALRM` blocked, it throws, since guest `SIGALRM` handlers are never run and signals are never left pending. The value is not raised to `tick / 16` as `itimerfix` does, and an interval below 1 ms throws, since the console's `hz`, and so that rounding, is unknown (1 ms covers any `hz` of 63 or more). `ITIMER_VIRTUAL` and `ITIMER_PROF` throw when armed, as process CPU time is not accounted, and read and disarm as zero.

 - On Linux, [direct memory](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) lives in one sparse memfd at file offset = physical address, so the [GPU imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) can share one udmabuf buffer object per 64 MiB of it. Released direct memory is not punched out of the file, because a live import of its chunk pins the pages and the GPU would keep reading the old ones: its pages stay committed (the process keeps the high-water mark of the direct memory it used) and are zeroed when the range is allocated again.
 - [system](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) runs no command. It follows FreeBSD 11's `lib/libc/stdlib/system.c` for a sandbox without `/bin/sh`: a null command returns 1 unconditionally, as that version does, and any command returns the wait status of a child that could not exec the shell and called `_exit(127)` (`0x7f00`). Whether the console's application sandbox has no shell, and whether `vfork` succeeds there (FreeBSD returns -1 when it fails), is unverified

A remap moves every page of a fully mapped range to the new address with the given protection and leaves the old range reserved; a multimap maps the same pages at a second address, anywhere in the AMM ranges, and a pool page goes back to the pool once its last mapping is unmapped; a multimap onto its own source range throws. A protection change sets the masked bits on every page of a fully mapped range; the memory type is recorded and ignored. A command on a range that is not fully mapped throws
 - [AMM PRT ranges](../../../core/libs/prx/libkernel/Apr/src/Apr.cpp) (libSceAmpr) - signatures, checks and their order taken from ampr_emu, where `MapAsPrt` is a map with the PRT flag and protection 0 and `AllocatePaForPrt` a memory type and protection change with mask 1019, both checking the buffer memory after its size; the effects are inferred from the names, not confirmed on a title. Unbacked PRT pages are zero-filled pages with GPU read access, so CPU reads see zeros instead of faulting and GPU writes fault instead of being dropped. `AllocatePaForPrt` backs each unbacked page with a pool page and sets the type and protection of backed ones; `RemapIntoPrt` moves a fully mapped range into a PRT range, its opcode argument (1011 when 0, as in ampr_emu) is recorded and ignored; `UnmapToPrt` returns the pages to the pool and zero-fills them again. A plain map, unmap or remap over a PRT range ends it; `AllocatePaForPrt`, `RemapIntoPrt` or `UnmapToPrt` outside a PRT range throws
 - [AMM kernel write commands](../../../core/libs/prx/libkernel/Apr/src/Apr.cpp) (libkernel) - signatures of `sceKernelWriteModifyMtypeProtectCommand` and `sceKernelWriteRemapIntoPrtCommand` taken from [ampr_emu's libkernel hook targets](https://github.com/drakmor/ampr_emu/blob/cfa85df379f6eeeb165d7badf9b648e266fe77b7/include/ampr_libkernel_hook_targets.h), which forward to the real kernel; the measure mode (`dst` null reports the size, `outSize` null skips the report) follows ampr_emu's measure-then-record calls, not confirmed on a title. The range, protection and mask checks mirror the `libSceAmpr` siblings, and the recorded bytes match them exactly so the submitted buffer executes on the existing paths
-- [sceCoredumpWriteUserString](../../../core/libs/prx/libkernel/System/src/Coredump.cpp) - imported by PPSA16064, not called during its start-up and added without an implementation; unknown signature
-- [sceCoredumpConfigDumpMode](../../../core/libs/prx/libkernel/System/src/Coredump.cpp) (libkernel, NID `gzLt9Qrauk0`) - imported by PPSA16833, whose executable does not load without it; added without an implementation; unknown signature
+- [sceCoredumpWriteUserString](../../../core/libs/prx/libkernel/System/src/Coredump.cpp) (libkernel, NID `32KQRUK13kI`) - `(uint32_t, const char* text, int)` follows the console's `libkernel.sprx` (SDK 4.5x build of `J03950001`) at 0x13050: a null `text` returns `0x81180000`; otherwise the three arguments go to syscall 601 (command 10), whose `EPERM` becomes `SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER` (0x81180003), `EINVAL` `0x81180000`, and a success returns the value the kernel wrote back. Measured on a PS5 (firmware 13.60) from a homebrew payload with no core dump handler: the call succeeds with 0, the kernel rejects a first argument above 15 or a third outside 0 to 256 with `0x81180000`, and a 2047-character text is accepted. Those checks are reproduced and anything else returns 0; nothing is recorded, as there is no dump, and what the two numbers mean is unknown. PPSA16064 imports it
+- [sceCoredumpConfigDumpMode](../../../core/libs/prx/libkernel/System/src/Coredump.cpp) (libkernel, NID `gzLt9Qrauk0`) - `(int mode)` follows the same `libkernel.sprx` at 0x134D0: a mode other than 1 returns `0x81180000`; mode 1 issues syscall 601 (command 16, arguments 0 and 1) and returns 0 whether or not it fails, since only a raw return of 22 would map to `0x81180000`. No dump is produced here, so mode 1 returns 0 without the syscall. PPSA16833 imports it
+- [sceCoredumpGetStopInfoGpu_Agc](../../../core/libs/prx/libkernel/System/src/Coredump.cpp) (libkernel, NID `Jrs7UUkGOFo`) - `(void* info, size_t size)` follows the same `libkernel.sprx` at 0x137E0: a null `info` returns `0x81180000`; syscall 601 (command 21) failing with `EPERM` returns `NOT_IN_COREDUMP_HANDLER`; otherwise two `libSceAgcDriver` imports (NIDs `+NIAY3DWpOw` and `LgctzJSGy7s`, names unknown) decide between `0x81180005` and, for a `size` of 8, storing the second one's 64-bit result and returning 0, with any other size returning `0x81180000`. The handler is never invoked here, so a non-null `info` returns `NOT_IN_COREDUMP_HANDLER` without writing, assuming `EPERM` outside the handler as above; the AGC branch is not reached
 - [sceKernelInternalMemoryGetModuleSegmentInfo](../../../core/libs/prx/libkernel/Module/src/ModuleInfo.cpp) (libkernel) - the `(InternalSegmentInfo* result)` signature, the 16-byte `{address, size}` result and the choice of the main program's first segment follow [fpPS4](https://github.com/red-prig/fpPS4/blob/04cefd43e6fddd1ab033e7980cd356d14c964905/kernel/ps4_libkernel.pas#L343-L355) only, which fills it through its `sceKernelGetLibkernelTextLocation` from the first segment of `eboot.bin`; whether the console reports that segment, the text of libkernel itself or the calling module's is unknown. The segment is the first one `sceKernelGetModuleInfo` reports for the main program, and 0 is returned. A null result throws. 44 audited titles that bundle their own `libc.prx` import it; no call has been observed
 - [sceKernelGetModuleInfoForUnwind](../../../core/libs/prx/libkernel/Module/src/Module.cpp) (libkernel) - on Linux the tables come from `sceKernelGetModuleInfoFromAddr`, whose `eh_frame_size` includes the zero terminator, as measured on firmware 13.60 (reported in [#2419](https://github.com/boykopovar/AnyPS5/issues/2419), not reproduced here); on Windows it is assumed to stop before the terminator. LLVM libunwind's `CFI_Parser::findFDE` stops at the terminator or the length, whichever comes first, so it finds the same FDEs either way. Only the main executable and `.guest.prx` images report tables; other host images report none, as on Windows
 - [sceKernelGetModuleInfoForUnwind](../../../core/libs/prx/libkernel/Module/src/Module.cpp) (libkernel) - on Windows the `.ehmeta` tables and the image file name are cached per allocation base and dropped after a loader free (`dlclose`, `sceKernelStopUnloadModule`, the thread atexit release) when the module is no longer loaded. A table changed in place, or an image freed by anything other than the loader, is not noticed. An address inside an image of the Windows loader's module list whose tables are cached is resolved with `RtlPcToFileHeader` and no `VirtualQuery`; other addresses, and images without tables, still use `VirtualQuery`. The `.eh_frame` walk that finds its end is done once per image instead of once per call

 - [malloc_usable_size](../../../core/libs/prx/libc/src/ApplicationHeap.cpp) (libc) - with the default allocator it returns the size the block was requested with (the range registered for it), not the rounded-up chunk size Sony's allocator reports; both satisfy "at least the requested size", and bytes past the request would not be write-watched. With an application allocator it calls entry 9 of the replacement table (`malloc_usable_size` in KytyPS5's `MallocReplace` order) and throws when the table leaves it null, like `malloc_stats_fast`
 - [malloc, calloc, realloc, memalign, aligned_alloc and reallocalign](../../../core/libs/prx/libc/src/FileAndHeap.cpp) (libc) - follow FreeBSD 11.4 `contrib/jemalloc/src/jemalloc.c` for failures, not measured on the console: a size the default heap rejects or the guest arena cannot place (including a `calloc` product that overflows) returns null with `errno` `ENOMEM`, and `memalign` and `aligned_alloc` return null with `EINVAL` for an alignment that is zero or not a power of two. FreeBSD's libc has no `memalign`, so setting `errno` there is assumed. A host commit failure for a block that fits in the arena (Windows `ERROR_NOT_ENOUGH_MEMORY`, `ERROR_OUTOFMEMORY` or `ERROR_COMMITMENT_LIMIT`, Linux `ENOMEM`) resets and releases the reserved range and returns null with `ENOMEM`; any other commit failure releases the range and throws. `reallocalign` returns null with `EINVAL` for an invalid alignment and `ENOMEM` like the others, which is an assumption as it is not in FreeBSD. `realloc(ptr, 0)` frees the block and returns null, where FreeBSD 11.4's jemalloc 4.5 resizes it to one byte and returns a block
 - [reallocf](../../../core/libs/prx/libc/src/FileAndHeap.cpp) (libSceLibcInternal, implemented in libc) - follows FreeBSD 11 `lib/libc/stdlib/reallocf.c` on top of this libc's `realloc`, not measured on the console: size 0 frees the block and returns null as `realloc` does here, so the block is not freed twice; when `realloc` fails because the application allocator returns null or the default heap rejects the size, the block is freed through the same allocator, `errno` is `ENOMEM` and null is returned. Other failures (a commit failure that is not out of memory, an unknown pointer) throw, as they do for `realloc`
+- [sceLibcMspaceReallocalign](../../../core/libs/prx/libc/src/Mspace.cpp) (libSceLibcInternal, implemented in libc) takes `(void* heap, void* block, size_t alignment, size_t size)`, the order of the console's `libSceLibcInternal.sprx` (SDK 4.5x build of `J03950001`, 0x13880, whose internal routine at 0x12390 treats the third argument as the alignment and, for a null block, passes it to the routine `sceLibcMspaceMemalign` uses). Measured on a PS5 (firmware 13.60) from a homebrew payload: a null block with alignment 4096 and size 100 returns a 4096-aligned block; an alignment of 0 or 3 succeeds and 100 gives a 128-aligned block, as the routine raises it to at least 32 and to the next power of two; an alignment of 2^63 or more returns null, keeps the block and leaves `errno` alone; and a size of 0 returns a block (the same one when it is already suitable) instead of freeing it. A block that is aligned and large enough is kept where it is, without giving back the bytes past the new size as the console's in-place resize does
 - [acosl](../../../core/libs/prx/libc/src/Math.cpp) (libc) - computed by the host's math library, like the other libc math functions here, not by the console's (FreeBSD msun ld80 code in Sony's `libc.prx`): results can differ from the console's in the last bit, and on Linux glibc sets `errno` to `EDOM` for `acosl` outside [-1, 1] where msun only raises the floating-point exception. `long double` is the x87 80-bit format, as Sony's `frexpl` uses it (`fldt 0x8(%rsp)`, result in `st(0)`)
 - [atanl, sinl, cosl, tanl, sinhl, coshl, tanhl, expl, exp2l, logl, log10l and powl](../../../core/libs/prx/libc/src/Math.cpp) (libc) - computed by the host's math library, as `acosl` is, not by the console's FreeBSD msun ld80 code: results can differ from the console's in the last bit (glibc's `log10l(1000)` is not exactly 3), and on Linux glibc sets `errno` to `EDOM` or `ERANGE` where msun only raises the floating-point exception. `ldexpl` and `truncl` are exact operations and give the console's result; `logb` and `remainder` give the console's value too, but on Linux glibc sets `errno` (`ERANGE` for `logb(0)`, `EDOM` for `remainder` by zero or of an infinity) where msun only raises the floating-point exception
 - [std_execute_once](../../../core/libs/prx/libc/Export.cpp) (libc) - assumed to be the plain-named twin of `std::_Execute_once` (`_ZSt13_Execute_onceRSt9once_flagPFiPvS1_PS1_ES1_`, the callee of Dinkumware `call_once`): it delegates there and gets the [thread.once.callonce] semantics already verified for that symbol (one invocation per flag, concurrent callers block until it completes, and a failing or throwing invocation leaves the flag unready so the next caller runs it). The name equivalence is not confirmed on a title, and the callback convention (called with (null, arg, null), non-zero return meaning success) is the twin's, unverified for this symbol

 - [getc_unlocked, putc_unlocked, getchar_unlocked, putchar_unlocked](../../../core/libs/prx/libc/src/StandardStreams.cpp) (libc) - byte I/O uses the host unlocked operations; guest EOF/error flags and macro counters follow `FileStream`. Linux status queries use `feof_unlocked`/`ferror_unlocked` because [glibc `feof`](https://github.com/bminor/glibc/blob/d2097651cc57834dbfcaa102ddfacae0d86cfb66/libio/feof.c) and [`ferror`](https://github.com/bminor/glibc/blob/d2097651cc57834dbfcaa102ddfacae0d86cfb66/libio/ferror.c) can acquire the stream lock. Windows uses [the CRT no-lock byte operations](https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/fgetc-nolock-fgetwc-nolock) and `feof`/`ferror`, verified under a held stream lock on UCRT. Console behavior and other host CRTs remain unverified.
 - [fgetws, getwc, getwchar, putwc, putwchar](../../../core/libs/prx/libc/src/FormattingWide.cpp) (libc) - wide stream I/O encodes and decodes wide characters as UTF-8 on the underlying byte stream; `fgetws` reads characters into the destination buffer until newline or EOF and null-terminates, returning null on stream error. Console wide stream buffering and encoding details remain unverified.
 - [ftrylockfile](../../../core/libs/prx/libc/src/RuntimeSupport.cpp) (libc) - tries the host CRT stream lock that `flockfile`, `funlockfile` and each locking host stdio call on the stream take, so it returns -1 while another thread holds the stream through `flockfile` or is inside such a call, and 0 when it acquires the lock or already owns it (recursively, released by as many `funlockfile` calls), as FreeBSD 11 [`_ftrylockfile`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/stdio/_flock_stub.c#L89-L104) does. A libc export holds the lock only for each host call it makes, not across several host calls or while it updates the guest `FILE` prefix. Linux uses glibc `ftrylockfile`. UCRT has no try variant of `_lock_file`, so Windows calls `TryEnterCriticalSection` on the `CRITICAL_SECTION` that `_lock_file` enters, found through the private UCRT stream layout (`__crt_stdio_stream_data` in `ucrt/inc/corecrt_internal_stdio.h`, unchanged from Windows SDK 10.0.19041 to 10.0.26100); another CRT or a change of that layout breaks it. A null or closed stream throws where FreeBSD dereferences it
+- [fgetln](../../../core/libs/prx/libc/src/StandardStreams.cpp) (libSceLibcInternal, implemented in libc) throws: in the console's `libSceLibcInternal.sprx` (SDK 4.5x build of `J03950001`, 0x5FE80) the export is a `hlt` instruction, which faults in user mode and ends the process
 - [Wide-character conversions](../../../core/libs/prx/libc/src/Multibyte.cpp) (libc) - The wide `wcsto*` functions parse the ASCII prefix of the guest string, as the C locale accepts only ASCII white space and digits. [`wcsrtombs`](../../../core/libs/prx/libc/src/Multibyte.cpp) uses the guest's single-byte C locale through `wcrtomb`; other encodings and shift states are not supported
 - [realpath](../../../core/libs/prx/libc/src/RealPath.cpp) (libc) follows FreeBSD 11's [`realpath.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libc/stdlib/realpath.c) except for symlinks. The console's guest filesystem has none, so a host symlink under the guest root is followed for existence and type but not expanded, and `..` drops the previous component lexically, as `Resolve` does for every guest path. Through a host link `linkdir -> sub/deep`, `linkdir/../x` gives `x` beside the link, not beside its target.
 - [strtod, strtof, strtold](../../../core/libs/prx/libc/src/Strings.cpp) (libc) - `NAN(n-char-sequence)` converts to the quiet NaN that `nan` and `nanf` return, negated after a minus sign, and ignores the sequence as they ignore their tag. This is inferred from C17 7.12.11.2p2, which makes `nan("n")` equivalent to `strtod("NAN(n)", NULL)`, and not observed on the console. No console `nanl` was observed, so `strtold` returns the x87 default quiet NaN (exponent `0x7fff`, significand `0xc000000000000000`)

Subject: [PATCH 0865/1000] perf(agc): share unchanged shader registry chunks
 between published versions

PublishRegisteredShader copied the whole code-address map, with every
header vector and snapshot reference, for each registration under the
driver mutex, so a title registering its shaders while it loads paid
O(n^2). The registry now keeps its entries in address-ordered chunks of
at most 64 shared by every version that has not changed them; a write
clones only the chunk it touches.

Subject: [PATCH 0866/1000] fix(libkernel): leave a blocked SIGALRM expiry
 pending

An ITIMER_REAL or alarm expiry while SIGALRM is blocked is marked on the
pending set of sigtimedwait instead of throwing, as kern_psignal leaves a
blocked signal pending. sigwait, sigwaitinfo and sigtimedwait take it,
repeated expiries merge into one pending signal, and unblocking it runs a
guest handler on the unblocking thread or, with the default disposition,
exits the process with status 142 as FreeBSD's default action does.

The expiry rechecks the mask after marking the signal, so an unblock that
races it does not leave SIGALRM pending while unblocked, and TakePending
clears the bit with the value it read so one signal is taken once.

As on Windows, a directory registered with `NOTE_EXTEND` is accepted but never receives it: XNU reports a move between directories as `NOTE_WRITE` alone, with `NOTE_LINK` for a subdirectory
 - [Windows file identity](../../../core/libs/prx/libkernel/File/src/NativeStat.cpp) (libkernel) - `stat` and `fstat` report the volume serial number as `st_dev` and the 64-bit file index folded into the guest's 32-bit `st_ino` (never 0), so two different files can in principle share an `st_ino`; the fold is not taken from a reference. `st_nlink` is clamped to 65535, the width of the guest field. The call keeps the `_wstat64` values when `GetFileInformationByHandle` fails
 - [lstat of a Windows symbolic link](../../../core/libs/prx/libkernel/File/src/NativeStat.cpp) (libkernel) reports a link whose target is relative, as `symlink` creates them, with the link's own times, `st_dev` and `st_ino`, mode `S_IFLNK | 0777` and the length of the target `readlink` returns as `st_size`. FreeBSD gives a new link `0777` less the creating process's umask, which the host does not keep, so the permission bits are not the console's. A link with an absolute target, a junction and any other reparse point throw, as for `readlink`

An expiry delivers nothing: with `SIG_IGN` it is dropped, with the default disposition the process exits with status 142, and with a handler, or with `SIGALRM` blocked, it throws, since guest `SIGALRM` handlers are never run and signals are never left pending. The value is not raised to `tick / 16` as `itimerfix` does, and an interval below 1 ms throws, since the console's `hz`, and so that rounding, is unknown (1 ms covers any `hz` of 63 or more). `ITIMER_VIRTUAL` and `ITIMER_PROF` throw when armed, as process CPU time is not accounted, and read and disarm as zero.

With `SIG_IGN` an expiry is dropped. With `SIGALRM` blocked it is left on the pending set of `sigtimedwait`, as `kern_psignal` does, where `sigwait`, `sigtimedwait` and `sigwaitinfo` take it; unblocking it runs a guest handler on the unblocking thread, and with the default disposition exits the process with status 142. Unblocked, the default disposition exits the process with status 142 and a handler throws, since guest `SIGALRM` handlers are never run from the timer thread.

 - On Linux, [direct memory](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) lives in one sparse memfd at file offset = physical address, so the [GPU imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) can share one udmabuf buffer object per 64 MiB of it. Released direct memory is not punched out of the file, because a live import of its chunk pins the pages and the GPU would keep reading the old ones: its pages stay committed (the process keeps the high-water mark of the direct memory it used) and are zeroed when the range is allocated again.
 - [system](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) runs no command. It follows FreeBSD 11's `lib/libc/stdlib/system.c` for a sandbox without `/bin/sh`: a null command returns 1 unconditionally, as that version does, and any command returns the wait status of a child that could not exec the shell and called `_exit(127)` (`0x7f00`). Whether the console's application sandbox has no shell, and whether `vfork` succeeds there (FreeBSD returns -1 when it fails), is unverified
 - [sceKernelWriteThrottlingStatus](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) reports no write throttling: the host SSD has no write budget, so the first qword of the 32-byte status is set to `UINT32_MAX` and the rest is zeroed; returns `EFAULT` (`0x8002000e`) when passed a null status buffer pointer. PPSA17221 reads only that qword: it multiplies it by 64 KiB and compares the product with byte thresholds up to 0x4AF00000 to pick one of five tiers. When the call fails the title assumes 0x4B000001 bytes, which selects the same top tier as `UINT32_MAX`.

 - [mlockall, munlockall](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) (libkernel) - `mlockall` returns `EINVAL` for zero or unknown flags. Valid `MCL_CURRENT` throws because it would lock host stacks, heaps, modules and driver mappings along with guest memory; `MCL_FUTURE` throws because later mappings are not tracked for locking. FreeBSD 11.4's `sys_munlockall` (`sys/vm/vm_mmap.c`:1133-1165) checks `priv_check(td, PRIV_VM_MUNLOCK)` first (returning `EPERM` without it) and unwires the user map (`vm_map_unwire` over `vm_map_min`...`vm_map_max` with `VM_MAP_WIRE_HOLESOK`). Returning 0 unconditionally assumes the calling process is privileged. `munlockall` unlocks memory locked by `mlock` (`VirtualUnlock` on Windows, tolerating `ERROR_NOT_LOCKED` for pages never locked, and `munlockall` on Linux). On main, XPSemu (PPSA97358) fails to load at these imports (mlockall #4386, munlockall); their calls in QEMU `os-posix.c` execute only when `-overcommit mem-lock=on` is enabled. The call has not been observed in a run with this implementation.
 - [socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) creates only `SOCK_STREAM` and `SOCK_DGRAM` sockets in `AF_INET` and `AF_INET6`. A type that FreeBSD 11.4's inet domain has no protocol for in any configuration ([`in_proto.c`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/netinet/in_proto.c) has no `SOCK_RDM` entry and no unknown type) fails with `EPROTOTYPE` when the protocol is 0 and `EPROTONOSUPPORT` otherwise, as [`socreate`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c) does. `SOCK_RAW`, which `in_proto.c` always has (`socreate` creates it for a privileged process), and `SOCK_SEQPACKET`, which it has only in a kernel built with `SCTP`, fail with `EPROTONOSUPPORT`; whether the console allows either is not known. `SOCK_DGRAM` with `IPPROTO_UDPLITE` and `AF_UNIX` (`socketpair` supports it) fail with `EPROTONOSUPPORT` and `EAFNOSUPPORT` where FreeBSD creates the socket
 - [sigtimedwait](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) waits on a process-wide pending set instead of throwing: a signal raised while blocked stays pending and is taken by `sigwait`, `sigwaitinfo` or `sigtimedwait`, delivered to the handler when `_sigprocmask` unblocks it, or delivered by `pause`. The set covers all 128 signals and the lowest number that is pending and in the set is selected (FreeBSD specifies the lowest number only among real-time signals). Selection, `EAGAIN` on timeout, `EINVAL` for a `tv_nsec` outside 0 to 1000000000 while nothing is pending and `NULL` timeout blocking indefinitely follow FreeBSD's [sigtimedwait(2)](https://man.freebsd.org/cgi/man.cgi?query=sigtimedwait). `sigwait` returns 0 with the number in its output, as POSIX specifies, and `sigwaitinfo` and `sigtimedwait` return the number, as FreeBSD does. The guest `siginfo_t` follows FreeBSD 11's `sys/sys/siginfo.h`: 80 bytes, `si_signo` at 0, `si_code` at 8, `si_pid` at 12, `si_uid` at 16, `si_addr` at 24, `si_value` at 32 and `si_band` at 40; only `si_signo`, `si_code` (`SI_USER`) and `si_pid` (the guest pid) are written, `si_uid` stays 0 because no uid is modelled, and the console's layout is not verified. PPSA85300 imports `sigtimedwait` and fails to load without it; its only call site is VLC's `vlc_writev` ([filesystem.c](https://github.com/videolan/vlc/blob/6de05adcbaf2e8b85fe86aad4169393098628119/src/posix/filesystem.c#L243-L278)), which polls with a zero timeout to drain a `SIGPIPE` only after `writev` fails with `EPIPE`. The waits are not cancellation points and an unblocked caught signal does not interrupt them with `EINTR`, where FreeBSD's `sigwaitinfo` and `sigtimedwait` may return it. `SIGPIPE` has no host equivalent and is never raised by a host write here (see `read, write and vector I/O`), so VLC's drain finds nothing
-- [pause, sigsuspend, sigwait, sigwaitinfo](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) take the pending set of `sigtimedwait` instead of throwing. `pause` waits for a pending signal that is not blocked and whose disposition can be delivered, runs its handler on the calling thread and returns -1 with `EINTR`; an ignored signal is discarded and the wait continues, and it never returns for a signal whose handler cannot run. A signal whose registered handler has `SA_SIGINFO` still throws, and one whose disposition is the default action and that has no host equivalent (every signal except 2, 4, 6, 8, 11 and 15) is neither delivered nor discarded: it stays pending until a wait takes it, where FreeBSD runs the default action, which terminates the process for most of them.

Only handlers without `SA_SIGINFO` on the signals `signal` already delivers (`SIGINT`, `SIGILL`, `SIGABRT`, `SIGFPE`, `SIGSEGV`, `SIGTERM`) run, the same way `signal` handlers do; their mask and flags are not applied. `SA_SIGINFO` handlers are recorded but never called, since that needs FreeBSD's `siginfo_t` and `ucontext_t`, and neither are the handlers of other signals (`SIGBUS`, `SIGHUP`, ...), whether they are set by `sigaction` or by `signal`, which records them too (every number from 1 to 128, with `SA_RESTART` and an empty mask replacing what `sigaction` stored; `SIGKILL` and `SIGSTOP` accept only the default handler in both calls, as in FreeBSD's `kern_sigaction`). `raise` and `kill` accept every number from 1 to 128 now: a blocked one stays pending on the set of `sigtimedwait`, an unblocked one whose handler is registered runs it on the calling thread, and an unblocked one that has no host equivalent and no handler still fails with `EINVAL`, where FreeBSD runs its default action. `raise` of an `SA_SIGINFO` handler still throws instead of terminating
 - [kill, killpg](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) follow FreeBSD's `kern_kill` and `killpg1` for the only guest process: `EINVAL` for signals outside 0 to 128 and for negative `killpg` process groups, signal 0 only checks that the target exists, and its own pid, 0 and minus its own pid (the guest is taken to lead its own process group) signal it through `raise`, so they share `raise`'s limits above. Any other pid, and -1, which skips the caller, report `ESRCH`, so `EPERM` is never reported

Subject: [PATCH 0867/1000] feat(agc): implement 11_11_10 float color targets
 through 32-bit uint attachments

Color format 7 (COLOR_11_11_10, float) keeps its 10-bit component in the
low bits; with the reversed component order (COMP_SWAP 2) that is blue,
with red in the high 11 bits. Vulkan has no such layout, so the target was
refused at decode.

Render it the way 10_11_11 unorm targets are rendered: an R32_UINT
attachment, the reversed export mapping 0xc6, and a new
ColorExportPacking::Float11_11_10 that makes the pixel shader pack each
export with the format-43 image store conversion (toward zero, overflow to
the largest finite value, negatives to zero, NaN kept). Blending, partial
writes, 16-bit integer exports, DCC and the other component orders throw.

AI-assisted: yes

 - The [dispatches that follow a compute queue's wait](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Dispatch/DispatchAhead.cpp) (libSceAgcDriver), up to the next wait that memory does not satisfy, a packet that writes guest memory other than a label, or a conditional packet, are resolved (memory captured, shader recompiled) when the wait passes, as the CP reads them right after it; the graphics queue is exempt (`APS5_GROUP_CAPTURE_ALL_QUEUES=1` includes it). The device still reads guest memory when the dispatch is issued; when that memory no longer matches the capture, the dispatch is resolved again from current memory.
 - [PA_CL_CLIP_CNTL](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - `DX_LINEAR_ATTR_CLIP_ENA` (bit 24) clear is drawn like bit 24 set, with Vulkan's clipping of `NoPerspective` outputs; what a clear bit changes on the console is undocumented.
 - [10_11_11 unorm color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) render into R32_UINT attachments: the pixel shader packs each export, rounded to nearest even like format-30 image stores, which is assumed to match the CB's conversion.
+- [11_11_10 float color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) render into R32_UINT attachments: the pixel shader packs each export toward zero like format-43 image stores (overflow to the largest finite value, negatives to zero, NaN kept), which is assumed to match the CB's conversion; only the reversed component order (COMP_SWAP 2) is accepted.
 - [PA_SU_SC_MODE_CNTL.PROVOKING_VTX_LAST](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Pipeline.cpp) (libSceAgcDriver) uses Vulkan's last-vertex mode for native primitives. Bit 19 follows [opengnm's `flatshade_first` mapping](https://github.com/blackbearreloaded/ps5-opengl/blob/db752da4c89380af228497b5b6852163a4e61069/src/gallium/ps5/ps5_screen.c#L2244); vertex selection follows [Vulkan](https://docs.vulkan.org/spec/latest/chapters/drawing.html#drawing-primitive-topologies), without console measurements. A [rect-list](../../../core/shader/recompiler/SpirvBackend/src/RectListShaders.cpp) draw in last mode gives all four corners of each rectangle the flat inputs of its third vertex through the generated control stage, as first mode gives them those of its first, so Vulkan's choice of provoking vertex for the tessellated triangles does not matter; which vertex the console takes for a rectangle is not measured either. Last mode throws without `VK_EXT_provoking_vertex`, for generated mesh or tessellation primitives, explicit per-vertex flat inputs, and triangle strips whose pixel shader reads a vertex slot itself (`v_interp_mov_f32`, or 16-bit interpolation, which is not checked yet), since the vertex order of odd strip triangles [depends on the device](https://docs.vulkan.org/refpages/latest/refpages/source/VkPhysicalDeviceFragmentShaderBarycentricPropertiesKHR.html). `v_interp_p1_f32` and `v_interp_p2_f32` read P10 and P20 against the guest's I and J, which come from `gl_BaryCoordKHR` in the same vertex order as the per-vertex values, so the order cancels out and strips with only those reads draw. A FLAT_SHADE input without pass-through that is read through `v_interp_mov_f32` P10 and not P20 [returns the provoking vertex's value](../../../core/shader/recompiler/Optimization/src/ShaderInfoCollector.cpp), like P0. ps5-opengl reads every flat input that way, and its driver passes the GL 4.6 CTS on a PS5 (#1413). The lane itself was not measured on the console, so with the first provoking vertex such a shader throws.
 - [Dual-source blending](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) takes the MRT1 export as the second source of the MRT0 blend, as RADV and radeonsi program it; what the CB does with other export or target layouts is unknown, so they throw.
 - [Blending into reversed-order color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - 8_8_8_8 and 16_16_16_16 targets with `COMP_SWAP` 2 or 3 keep the exported alpha in their first channel and red or blue in their fourth, which Vulkan would blend with the color and the alpha equation respectively. The color block is taken to blend in shader export order and apply `COMP_SWAP` afterwards: the alpha equation and every source-alpha factor use the exported alpha, and the destination alpha is the first channel. This follows the `CB_TARGET_MASK` text of the AMD [SI](https://xorg.freedesktop.org/docs/AMD/old/SI_3D_registers.pdf) (p. 229) and [CIK](https://xorg.freedesktop.org/docs/AMD/old/CIK_3D_registers_v2.pdf) (p. 238) register references ("the order of components after blending and before COMP_SWAP is applied"). RADV builds `CB_BLENDn_CONTROL` without regard to the swap ([radv_pipeline_graphics.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/amd/vulkan/radv_pipeline_graphics.c#L650-L709)) and renders R4G4B4A4, B4G4R4A4, R5G5B5A1 and B5G5R5A1 with `SWAP_STD_REV` and `SWAP_ALT_REV` ([vk_format.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/vulkan/util/vk_format.c#L43-L48), [ac_formats.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/amd/common/ac_formats.c#L609-L624)). Mesa CI's Navi10 (gfx1010) CTS run ([job 112381553](https://gitlab.freedesktop.org/mesa/mesa/-/jobs/112381553), [112381554](https://gitlab.freedesktop.org/mesa/mesa/-/jobs/112381554)) passes all 400 `blend.format.<format>.states` cases of each of those formats, including separate alpha and destination-alpha factors. It is not measured on gfx1013 or on 8_8_8_8 and 16_16_16_16 targets. Factor pairs Vulkan applies per channel are used directly. Otherwise the pixel shader only copies values: it writes the exported alpha, each channel's own export or the constants 0 and 1 into a second color at location 0 index 1 (and 1 into a channel of the first color whose source factor is ONE, moving its export into the factor), and the blend forms every factor, `1 -` and product from those copies through `SRC1_COLOR`/`SRC1_ALPHA` factors. The blend unit therefore rounds them as it rounds a plain Vulkan blend of the same export; Vulkan does not require a second-source color to be converted like the first, but on an RTX 5080 and lavapipe every reversed-order case of the execution test is bit-identical to the same draw into a `SWAP_STD` target, which the test checks. Factor combinations that copies cannot express (for example `ONE_MINUS_SRC_ALPHA` in the alpha equation with `SRC_COLOR` in the color equation), sRGB, SNORM and integer targets, constant and second-source factors, destination-alpha and `SRC_ALPHA_SATURATE` factors in the color equation, different color and alpha operations, MIN or MAX with factors other than ONE, other color exports when the blend needs the second color, and devices without `dualSrcBlend` throw. Gran Turismo 7 (PPSA01317) blends `CB_BLEND0_CONTROL` 0x65010504 into such a target (#4782).

Subject: [PATCH 0868/1000] fix(agc): refuse rounding 11_11_10 float targets
 and resolves of packed color targets

An 11_11_10 float color target with CB_COLOR_INFO ROUND_MODE (bit 18) clear
asks the CB to round, but the export packing truncates toward zero, so such a
target now throws. A CB resolve whose source is a packed 10_11_11 unorm or
11_11_10 float target would resolve the raw R32_UINT words, which an integer
resolve cannot average, so it now throws at decode.

Subject: [PATCH 0869/1000] test(agc): refuse an additive blend into an
 11_11_10 float target

The blend-refusal case used CB_BLEND_CONTROL 0x60010001, which is
ONE * source + ZERO * destination: a replace blend that writes the source
unchanged. A packed target can draw such a blend with blending disabled,
so the case now uses the additive blend 0x60010101, which a packed target
must still refuse.

Subject: [PATCH 0870/1000] fix(shader): collect packed ancillary readers
 without recursion

lowerPackedAncillary follows the selects, phis and identities that
forward the packed ancillary word to its readers by recursing once per
link (collectReaders), with a linear scan of the visited list at each
step. A long forwarding chain overflowed the stack of the thread that
compiles the shader: PPSA01317 crashes about 30 s into boot in that
recursion on a guest job thread, with a 0xc00000fd stack overflow inside
malloc. The readers are now collected with an explicit stack and a
visited set, in the same order.

Subject: [PATCH 0871/1000] fix(recompiler): drop a sample-adjust S# dword 3
 that sets only reserved bits

An image_sample_*_a sampler whose dword 3 is built only from values
inside the reserved bits 12-29 was refused with "GetSamplerResource
dword 3 is not a valid runtime value" when the value was not an OR at the
top. The reserved bits of a sample-adjust S# are already dropped term by
term from an OR (canonicalizeSampleAdjustDword3); a dword 3 whose
possible bits all lie in that mask, such as a shifted field with nothing
else, is now dropped whole the same way. PPSA01317 builds such a dword 3
from a wave ballot shifted to bit 12 for image_sample_a in a pixel
shader. A plain image_sample with the same S# is still refused.

Subject: [PATCH 0872/1000] fix(agc): trace the title threads that register
 shaders

Shader registration and the shader ABI resolves run on the title's own
threads, which never bound a trace buffer, so their Shader.Register and
Shader.Resolve* scopes were missing from every trace and summary. Those
entry points now bind the calling thread as `title` with the 32,768-event
buffer the shader preparation threads use.

Each buffer uses `count * sizeof(TraceThread::Slice)` bytes (currently 32 bytes per event): 8 MiB at the default, 96 MiB at `3145728`, and 128 MiB at the maximum, per thread. The buffers are allocated even while waiting for the window to open, and formatting the trace uses additional memory. Shader preparation keeps its explicitly sized 32,768-event buffers, as does a title thread named `title` that binds one the first time it registers a shader or resolves a shader ABI. The GPU range limit stays 262,144. Summary-only sessions allocate no event buffers and do not read this setting. A larger buffer can still fill; use a shorter window or increase the count within the bound.
 
 Inside the window the queue workers and the presenter record every `PerformanceTimer` scope and stage as a complete event named after its frame timing key: `Driver.WorkerWait`, `Driver.Packet`, `Driver.Packet.draw`, `Graphics.Draw`, `Driver.Present`, `Driver.Present.inflight_wait`, `Vulkan.Retire` and so on. A slice shorter than 20 us is only counted: its time is in the thread's counter `<thread> folded` (milliseconds per present) and in the summary. A thread writes a present's counter sample at its first slice after the next present, so the last present of the window has no sample; its time is still in the summary. By default, each queue worker and presenter allocates a buffer for 262,144 events when it starts; a full buffer stops that thread's recording, sets `trace_dropped` and puts an instant event `trace buffer full` on the thread's track at the start of the first lost slice (slices are appended when their outer scope ends, so that can precede the last recorded slice by up to one outer-scope length), with the number of lost slices in `args.events_lost`. When the window closes, the presenter formats the trace once and a `ProfileOutput` writer thread writes `aps5-trace-<commit>-<pid>.json.gz` (Chrome trace-event JSON, opened by ui.perfetto.dev or chrome://tracing) and appends one line to `aps5-summary.jsonl`, both in `APS5_TRACE_DIR` or the working directory. A window that is still open when the title exits writes nothing.

On a PS5 (firmware 12.70), of the values 0, 1, 2 and -1,
pthread_spin_init, pthread_barrierattr_setpshared and

 - [__progname](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - unknown data export
 - [environ](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - data export pointing to a fixed empty environment so titles that import it load; it is not the environment libc's `getenv` reads, so it lists none of those variables and `setenv`/`putenv` changes do not appear in it
 - [seteuid, setegid, setuid, setreuid, setregid, setgroups, getgroups](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - the guest process is assumed to run as root, with real, effective and saved user and group ids 0. As in FreeBSD's `sys_seteuid`, `sys_setegid`, `sys_setuid`, `sys_setreuid` and `sys_setregid`, id 0 (or -1 for an unchanged `setreuid`/`setregid` id) is then accepted without a privilege check and changes no credential, so 0 is returned; any other id would change an id, which is not modelled, and throws. `setgroups` keeps the supplementary group list as `kern_setgroups` does (`NGROUPS_MAX` 1023, an empty list leaves the effective group as the only entry, a first entry other than 0 would change the effective group and throws) and `getgroups` reports it. The ids and privileges a title has on a console are unverified
-- [pthread_barrierattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Barrier.cpp) (libkernel) - PTHREAD_PROCESS_SHARED is accepted on the assumption that the console follows FreeBSD 11.0 libthr, which accepts it (9.0 rejects it with EINVAL); unverified on hardware. Guest code runs in one process, so a shared barrier behaves as a private one
 - [pthread_getname_np](../../../core/libs/prx/libkernel/Pthread/Posix/Thread.cpp) (libkernel) - a thread that has already been joined returns `ESRCH` (3) and its output buffer is left untouched, as measured on a PS5 (firmware 13.60) by the author of this entry; since [#4481](https://github.com/boykopovar/AnyPS5/pull/4481) the joined thread's object is retained, so the posix wrapper answers `ESRCH` for it instead of reading the retained name. A null name buffer is answered with `EFAULT` before that, an order the console table does not measure. The SCE sibling `scePthreadGetname` has no measured joined-thread behaviour on the console and still reads the retained object's name, so it is unchanged, as is the pre-existing dangling case of a thread that ended detached (its object is released at exit; see the scePthreadJoin entry)
 - [sceKernelGetOperationMode](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - the signature `(int* mode, int* submode)` comes from PPSA12544, which logs both values after the call and ignores the result. A homebrew payload on a PS5 (firmware 13.60) reads mode 2 and submode 0, nothing else is written, and the result register holds no status, so the function is taken to return nothing. Whether a title process reads the same values is unverified. Null outputs throw
 - [sceCoredumpGetStopInfoCpu](../../../core/libs/prx/libkernel/System/src/Coredump.cpp) (libkernel) takes `(void* info, size_t size)` as in the [Orbital type database](https://github.com/AlexAltea/orbital/blob/cc408367da6a6ebbf5ac1ac559fefeadc73b2831/tools/ida/db_types.json); the 16-byte, 8-byte-aligned block follows [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/5dfdb4b0b166e83dc9ae275001afb695f12c7174/src/SharpProspero/Interop/Kernel/KernelSystem.cs), which places coredump reads inside the handler. The handler is never invoked here, so a well-formed request returns `NOT_IN_COREDUMP_HANDLER` without reading or writing the block. Its value `0x81180003` follows [shadPS4](https://github.com/shadps4-emu/shadPS4/blob/e0a466753a1aacbc8db8253be685bf7ab4d9daae/src/core/libraries/kernel/coredump/coredump_error.h) and the NHL 27 (PPSA34063) call site reported in [#4275](https://github.com/boykopovar/AnyPS5/discussions/4275), not a PS5 measurement. The console validation order is unverified: null, unaligned or wrapping buffers and sizes other than 16 throw instead of guessing an argument error. Information from an active coredump handler remains unsupported

 - [sceKernelWriteThrottlingStatus](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) reports no write throttling: the host SSD has no write budget, so the first qword of the 32-byte status is set to `UINT32_MAX` and the rest is zeroed; returns `EFAULT` (`0x8002000e`) when passed a null status buffer pointer. PPSA17221 reads only that qword: it multiplies it by 64 KiB and compares the product with byte thresholds up to 0x4AF00000 to pick one of five tiers. When the call fails the title assumes 0x4B000001 bytes, which selects the same top tier as `UINT32_MAX`. What the value measures on hardware (a remaining budget or a rate) and the meaning of the other three qwords are unknown
 - [Windows directory descriptors](../../../core/libs/prx/libkernel/File/src/DirectoryDescriptor.cpp) (libkernel) take one snapshot of the directory, on the first `getdents`, `getdirentries` or non-zero `lseek` (`SEEK_SET` or `SEEK_CUR`), and keep it until it is discarded; `lseek` to offset 0 only discards the snapshot, and the next read lists the directory again, so every rewind costs O(entries) on the next read. `lseek` takes the offset as an entry index and `SEEK_CUR` with offset 0 only reports the index. `SEEK_END` throws, where the NUL descriptor used to return 0, because FreeBSD defines it relative to the directory size, which is not modelled. A negative result returns `EINVAL` and a `SEEK_CUR` offset that overflows returns `EOVERFLOW`, as FreeBSD `vn_seek` reports them. Names whose UTF-8 encoding exceeds the one-byte `d_namlen` limit are not representable in this guest directory-record layout: `getdents` returns `ENAMETOOLONG` without consuming the entry. Repeated calls therefore report the same error and entries after that name cannot be reached through this descriptor; FreeBSD's `getdents` behavior for host filenames that exceed its `MAXNAMLEN` is not verified. `getdirentries` still reports 0 through `basep` instead of the position of the block it read, so only 0 and values returned by `lseek` are valid offsets; FreeBSD offsets are filesystem cookies
 - [/dev/random and /dev/urandom](../../../core/libs/prx/libkernel/File/src/RandomDevice.cpp) (libkernel) opened for reading return a descriptor backed by the host null device whose reads are filled with host OS entropy (`getentropy`, `rand_s` on Windows); both paths behave the same, never block, and positioned reads ignore the offset (FreeBSD `random(4)`). Only the exact paths are recognised, `fstat`, `lseek` and `mmap` see the null device, and opening them for writing throws
-- [pthread_mutexattr_getpshared and pthread_mutexattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Mutex.cpp) (libkernel) store and report private or shared attributes, following FreeBSD 11 libthr [thr_mutexattr.c](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libthr/thread/thr_mutexattr.c). Invalid values return `EINVAL` without changing the attribute. Guest threads execute in one host process; sharing mutexes across processes is not modeled. Console behavior and invalid-attribute error precedence are unverified.
 - [pthread_condattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Cond.cpp) (libkernel) stores a private or shared attribute, following FreeBSD 11 libthr [thr_condattr.c](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libthr/thread/thr_condattr.c): a null or uninitialized attribute and values other than `PTHREAD_PROCESS_PRIVATE` (0) and `PTHREAD_PROCESS_SHARED` (1) return `EINVAL` without changing it. Guest threads execute in one host process; sharing condition variables across processes is not modeled. PSFlyCast (PPSA99247) imports it and fails to load without it. Console behavior is unverified.
 - [pthread_attr_getinheritsched, pthread_attr_setinheritsched, pthread_attr_getscope, pthread_attr_setscope, pthread_attr_getstackaddr](../../../core/libs/prx/libkernel/Pthread/Posix/Attr.cpp) (libkernel) follow FreeBSD 11 libthr ([thr_attr.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_attr.c), [thr_create.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_create.c)), not measured on the console: the scope defaults to `PTHREAD_SCOPE_SYSTEM` (2), only it and `PTHREAD_SCOPE_PROCESS` (0) are accepted and other values return `EINVAL`, and an inherit value other than `PTHREAD_INHERIT_SCHED` (4) or `PTHREAD_EXPLICIT_SCHED` (0) returns `ENOTSUP`. `pthread_attr_getstackaddr` returns the configured stack address pointer (null by default). A null output of `pthread_attr_getinheritsched` throws, since libthr writes through it unchecked. A thread keeps the scope it was created with, taken from the creating thread under `PTHREAD_INHERIT_SCHED`, and `pthread_attr_get_np` and `scePthreadAttrGet` report it, but every guest thread is a host thread at system scope, so process scope changes nothing
 - [Shared memory](../../../core/libs/prx/libkernel/File/src/SharedMemory.cpp) (libkernel) on Linux implements anonymous and named objects, bounded descriptor writes and seeks, and `shm_unlink` with effective read/write permission checks from FreeBSD 11. Named paths up to 1023 bytes use `/anyps5-shm-` plus SHA-1; collisions are not detected, and the namespace is shared across processes in the host mount namespace. Named creation applies the guest umask without changing the host mask. Linux procfs and `/dev/shm` are required. Operations use an advisory directory lock; external host operations bypass it, unrelated objects serialize, and descriptor operations require two spare host descriptors and compare device/inode with the initial descriptor identity on both the pinned-object and ordinary-file fallback paths. [Guest mappings](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) support shared and private mappings of these descriptors through the allocation tracker and pin a duplicate descriptor during validation and mapping; mapping requires one spare host descriptor; file-backed mappings use the write-watch scan fallback because aliases and descriptor writes bypass per-mapping tracking. Named objects and file-backed mappings on Windows remain unsupported. Invalid non-null name pointers, console behaviour and title compatibility remain unverified.

 - [pthread_kill](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) returns the error number like FreeBSD's `pthread_kill`: `EINVAL` for signals outside 0 to 128 and `ESRCH` for a null thread. Signal 0 reports any other thread handle as existing, without checking that the thread is still alive. A signal to the calling thread goes through `raise`, so it shares `raise`'s limits; a signal to another thread is left on the pending set for whichever thread waits for or unblocks it, since it is not delivered to the chosen thread, and a handle that is not a live guest thread returns `ESRCH` without touching it
 - [select](../../../core/libs/prx/libkernel/Socket/src/Socket.cpp) (libkernel) validates `tv_usec` but saturates a valid timeout beyond the remaining `steady_clock` range at `time_point::max()`, so the wait can continue effectively indefinitely. The console's behavior for a valid timeout outside the host clock's range is unknown.
 - [_fstatfs](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) fills the FreeBSD 11 `struct statfs` of the PS5 payload SDK with the host volume that holds the file: block size, transfer size, total, free and available blocks, maximum name length and the read-only, `nosuid` and `noexec` flags (on Windows only read-only, and `f_files` and `f_ffree` are 0, as NTFS has no fixed number of files). The filesystem type number and name, mount paths, owner, filesystem id and I/O counters are left 0 or empty, since they would describe a host mount, not a console one. Sockets and pipes return `EINVAL`, as FreeBSD's `getvnode` does; a Windows descriptor that is neither a file nor a pipe throws. Stremio Plus (PPSA74126) reads the free space before a download and only logs the other fields

+- [pthread_spin_lock](../../../core/libs/prx/libkernel/Pthread/Posix/Spinlock.cpp) (libkernel) - a lock taken again by the thread that holds it throws here.

[fpPS4](https://github.com/red-prig/fpPS4/blob/04cefd43e6fddd1ab033e7980cd356d14c964905/kernel/ps4_queue.pas#L643) instead returns `fflags` plus `0x80020000` when `fflags` is nonzero. Whether the console reads `data` or `fflags` and returns the raw errno or an SCE error code is unverified. No event delivered by the equeue here carries `EV_ERROR`, so the call returns 0 for every event `sceKernelWaitEqueue` reports
 - [pthread_cond_reltimedwait_np](../../../core/libs/prx/libkernel/Pthread/Posix/Cond.cpp) (libkernel) takes `(cond, mutex, usec)`, a relative timeout in microseconds, and is `scePthreadCondTimedwait` with POSIX error numbers. FreeBSD 11.4 has no such function; the signature comes only from shadPS4, which registers one function for this NID and for `scePthreadCondTimedwait` ([`condvar.cpp`](https://github.com/shadps4-emu/shadPS4/blob/3a9f57265d28975658f1ca941daa5c879c7a74bd/src/core/libraries/kernel/threads/condvar.cpp#L229-L234)). shadPS4 reads a 64-bit count; here it is the 32-bit `SceKernelUseconds` of the SCE twin, as for `sem_reltimedwait_np`. Unverified on the console
 - [sysctl kern.arandom](../../../core/libs/prx/libkernel/System/src/SystemConfiguration.cpp) (libkernel) serves FreeBSD 11's MIB {1, 37} (CTL_KERN, KERN_ARANDOM) and the "kern.arandom" sysctlbyname lookup through std::random_device, returning min(*oldLength, 256) random bytes. Following FreeBSD's sysctl_kern_arnd, a null buffer reports min(*oldLength, 256) without writing, a null length returns 0 without writing, and requests with a new value return EPERM (1) as the node is read-only. Cryptographic quality depends on the host's random device implementation.

Subject: [PATCH 0875/1000] feat(libkernel): add pthread_rwlockattr_getpshared
 and pthread_rwlockattr_setpshared

Measured on a PS5 (firmware 12.70): the getter reports 0, and of the
values 0, 1, 2 and -1 the setter accepts only 0 and checks the value
before the attribute. A null or uninitialized attribute, or a null
output, crashes the console; here it throws.

 - [select](../../../core/libs/prx/libkernel/Socket/src/Socket.cpp) (libkernel) validates `tv_usec` but saturates a valid timeout beyond the remaining `steady_clock` range at `time_point::max()`, so the wait can continue effectively indefinitely. The console's behavior for a valid timeout outside the host clock's range is unknown.
 - [_fstatfs](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) fills the FreeBSD 11 `struct statfs` of the PS5 payload SDK with the host volume that holds the file: block size, transfer size, total, free and available blocks, maximum name length and the read-only, `nosuid` and `noexec` flags (on Windows only read-only, and `f_files` and `f_ffree` are 0, as NTFS has no fixed number of files). The filesystem type number and name, mount paths, owner, filesystem id and I/O counters are left 0 or empty, since they would describe a host mount, not a console one. Sockets and pipes return `EINVAL`, as FreeBSD's `getvnode` does; a Windows descriptor that is neither a file nor a pipe throws. Stremio Plus (PPSA74126) reads the free space before a download and only logs the other fields
 - [pthread_spin_lock](../../../core/libs/prx/libkernel/Pthread/Posix/Spinlock.cpp) (libkernel) - a lock taken again by the thread that holds it throws here. On a PS5 (firmware 12.70) that call had not returned after 2 s, as FreeBSD 11.4 libthr [`thr_pspinlock.c`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libthr/thread/thr_pspinlock.c) spins forever
+- [pthread_rwlockattr_getpshared, pthread_rwlockattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Rwlock.cpp) (libkernel) - `pthread_rwlockattr_destroy` clears the attribute here, so a later get, or a set of 0, throws. On a PS5 (firmware 12.70) destroy leaves the attribute set; a get afterwards returned 0 with a stale value and a set of 0 returned 0
 - [sceKernelGetEventError](../../../core/libs/prx/libkernel/Equeue/src/EventAccessors.cpp) (libkernel) returns the event's `data` as an `int` when `EV_ERROR` (0x4000) is set in `flags` and 0 otherwise, as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/947627d10d4ef4b68ba3c0189aab6c368e70a8d2/src/kernel/eventQueue.cpp#L663) does and as FreeBSD 11's [kevent](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/kern_event.c#L1005) reports a failed change (`flags = EV_ERROR`, errno in `data`). [fpPS4](https://github.com/red-prig/fpPS4/blob/04cefd43e6fddd1ab033e7980cd356d14c964905/kernel/ps4_queue.pas#L643) instead returns `fflags` plus `0x80020000` when `fflags` is nonzero. Whether the console reads `data` or `fflags` and returns the raw errno or an SCE error code is unverified. No event delivered by the equeue here carries `EV_ERROR`, so the call returns 0 for every event `sceKernelWaitEqueue` reports
 - [pthread_cond_reltimedwait_np](../../../core/libs/prx/libkernel/Pthread/Posix/Cond.cpp) (libkernel) takes `(cond, mutex, usec)`, a relative timeout in microseconds, and is `scePthreadCondTimedwait` with POSIX error numbers. FreeBSD 11.4 has no such function; the signature comes only from shadPS4, which registers one function for this NID and for `scePthreadCondTimedwait` ([`condvar.cpp`](https://github.com/shadps4-emu/shadPS4/blob/3a9f57265d28975658f1ca941daa5c879c7a74bd/src/core/libraries/kernel/threads/condvar.cpp#L229-L234)). shadPS4 reads a 64-bit count; here it is the 32-bit `SceKernelUseconds` of the SCE twin, as for `sem_reltimedwait_np`. Unverified on the console
 - [sysctl kern.arandom](../../../core/libs/prx/libkernel/System/src/SystemConfiguration.cpp) (libkernel) serves FreeBSD 11's MIB {1, 37} (CTL_KERN, KERN_ARANDOM) and the "kern.arandom" sysctlbyname lookup through std::random_device, returning min(*oldLength, 256) random bytes. Following FreeBSD's sysctl_kern_arnd, a null buffer reports min(*oldLength, 256) without writing, a null length returns 0 without writing, and requests with a new value return EPERM (1) as the node is read-only. Cryptographic quality depends on the host's random device implementation.

Subject: [PATCH 0876/1000] fix(libkernel): reject PTHREAD_PROCESS_SHARED in
 pthread_condattr_setpshared and add pthread_condattr_getpshared

On a PS5 (firmware 12.70), of the values 0, 1, 2 and -1,
pthread_condattr_setpshared accepts only 0 and leaves the attribute
unchanged otherwise. pthread_condattr_getpshared reports 0 and returns
EINVAL for a null, uninitialized or destroyed attribute, also with a
null output. With an initialized attribute a null output crashes the
console; here it throws.

 - [sceKernelWriteThrottlingStatus](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) reports no write throttling: the host SSD has no write budget, so the first qword of the 32-byte status is set to `UINT32_MAX` and the rest is zeroed; returns `EFAULT` (`0x8002000e`) when passed a null status buffer pointer. PPSA17221 reads only that qword: it multiplies it by 64 KiB and compares the product with byte thresholds up to 0x4AF00000 to pick one of five tiers. When the call fails the title assumes 0x4B000001 bytes, which selects the same top tier as `UINT32_MAX`. What the value measures on hardware (a remaining budget or a rate) and the meaning of the other three qwords are unknown
 - [Windows directory descriptors](../../../core/libs/prx/libkernel/File/src/DirectoryDescriptor.cpp) (libkernel) take one snapshot of the directory, on the first `getdents`, `getdirentries` or non-zero `lseek` (`SEEK_SET` or `SEEK_CUR`), and keep it until it is discarded; `lseek` to offset 0 only discards the snapshot, and the next read lists the directory again, so every rewind costs O(entries) on the next read. `lseek` takes the offset as an entry index and `SEEK_CUR` with offset 0 only reports the index. `SEEK_END` throws, where the NUL descriptor used to return 0, because FreeBSD defines it relative to the directory size, which is not modelled. A negative result returns `EINVAL` and a `SEEK_CUR` offset that overflows returns `EOVERFLOW`, as FreeBSD `vn_seek` reports them. Names whose UTF-8 encoding exceeds the one-byte `d_namlen` limit are not representable in this guest directory-record layout: `getdents` returns `ENAMETOOLONG` without consuming the entry. Repeated calls therefore report the same error and entries after that name cannot be reached through this descriptor; FreeBSD's `getdents` behavior for host filenames that exceed its `MAXNAMLEN` is not verified. `getdirentries` still reports 0 through `basep` instead of the position of the block it read, so only 0 and values returned by `lseek` are valid offsets; FreeBSD offsets are filesystem cookies
 - [/dev/random and /dev/urandom](../../../core/libs/prx/libkernel/File/src/RandomDevice.cpp) (libkernel) opened for reading return a descriptor backed by the host null device whose reads are filled with host OS entropy (`getentropy`, `rand_s` on Windows); both paths behave the same, never block, and positioned reads ignore the offset (FreeBSD `random(4)`). Only the exact paths are recognised, `fstat`, `lseek` and `mmap` see the null device, and opening them for writing throws
-- [pthread_condattr_setpshared](../../../core/libs/prx/libkernel/Pthread/Posix/Cond.cpp) (libkernel) stores a private or shared attribute, following FreeBSD 11 libthr [thr_condattr.c](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libthr/thread/thr_condattr.c): a null or uninitialized attribute and values other than `PTHREAD_PROCESS_PRIVATE` (0) and `PTHREAD_PROCESS_SHARED` (1) return `EINVAL` without changing it. Guest threads execute in one host process; sharing condition variables across processes is not modeled. PSFlyCast (PPSA99247) imports it and fails to load without it. Console behavior is unverified.
 - [pthread_attr_getinheritsched, pthread_attr_setinheritsched, pthread_attr_getscope, pthread_attr_setscope, pthread_attr_getstackaddr](../../../core/libs/prx/libkernel/Pthread/Posix/Attr.cpp) (libkernel) follow FreeBSD 11 libthr ([thr_attr.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_attr.c), [thr_create.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_create.c)), not measured on the console: the scope defaults to `PTHREAD_SCOPE_SYSTEM` (2), only it and `PTHREAD_SCOPE_PROCESS` (0) are accepted and other values return `EINVAL`, and an inherit value other than `PTHREAD_INHERIT_SCHED` (4) or `PTHREAD_EXPLICIT_SCHED` (0) returns `ENOTSUP`. `pthread_attr_getstackaddr` returns the configured stack address pointer (null by default). A null output of `pthread_attr_getinheritsched` throws, since libthr writes through it unchecked. A thread keeps the scope it was created with, taken from the creating thread under `PTHREAD_INHERIT_SCHED`, and `pthread_attr_get_np` and `scePthreadAttrGet` report it, but every guest thread is a host thread at system scope, so process scope changes nothing
 - [Shared memory](../../../core/libs/prx/libkernel/File/src/SharedMemory.cpp) (libkernel) on Linux implements anonymous and named objects, bounded descriptor writes and seeks, and `shm_unlink` with effective read/write permission checks from FreeBSD 11. Named paths up to 1023 bytes use `/anyps5-shm-` plus SHA-1; collisions are not detected, and the namespace is shared across processes in the host mount namespace. Named creation applies the guest umask without changing the host mask. Linux procfs and `/dev/shm` are required. Operations use an advisory directory lock; external host operations bypass it, unrelated objects serialize, and descriptor operations require two spare host descriptors and compare device/inode with the initial descriptor identity on both the pinned-object and ordinary-file fallback paths. [Guest mappings](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) support shared and private mappings of these descriptors through the allocation tracker and pin a duplicate descriptor during validation and mapping; mapping requires one spare host descriptor; file-backed mappings use the write-watch scan fallback because aliases and descriptor writes bypass per-mapping tracking. Named objects and file-backed mappings on Windows remain unsupported. Invalid non-null name pointers, console behaviour and title compatibility remain unverified.
 - [sceKernelAddReadEvent and sceKernelAddWriteEvent](../../../core/libs/prx/libkernel/Equeue/Equeue.cpp) (libkernel): a write event reports the free space of the socket's send buffer in `data`, as FreeBSD 11.4's [`filt_sowrite`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c#L3358-L3382) reports `sbspace`: on Linux the host's `SO_SNDBUF` less the bytes `SIOCOUTQ` counts as queued, which include the host's per-packet overhead, so the space shrinks by somewhat more than the bytes sent. Windows has no query for that space and macOS is not wired up, so both report the whole `SO_SNDBUF`, which does not shrink as data is queued. Only guest sockets are supported; other descriptors and a low watermark above 1 throw

Subject: [PATCH 0877/1000] test(agc): draw exact UNORM8 codes into the swapped
 multisampled target

The case drew 0.5 green, which lies halfway between two UNORM8 codes, so a
device that rounds 127.5 up (llvmpipe, LLVM 20.1.2) failed the half-code
tolerance with red and blue correctly swapped. It now draws 64, 128 and 32
of 255 from its own pixel program and names the loaded and expected codes
when a sample differs.

Subject: [PATCH 0878/1000] fix(relinker): keep the Windows TLS rewrite from
 moving truncated branches

A short TLS access followed by a near branch with an operand-size prefix
decided the branch was relative from its flow kind and opcode alone, then
re-encoded it to the fall-through address or wrote its rel32 over the prefix
and opcode. Such a branch now counts as one that cannot move.

Subject: [PATCH 0880/1000] feat(shader): build the barycentric emulation
 stages from tessellation

On a device without geometry shaders, each triangle becomes a three-point
patch at tessellation level 1. The evaluation stage takes the corner
gl_TessCoord points at as its vertex and writes it as the weights, and
passes every vertex's parameters for raw reads. The vertex clip distances
are forwarded, so MoltenVK's stage interface matches the vertex output.

Subject: [PATCH 0881/1000] feat(agc): emulate barycentrics through
 tessellation without geometry shaders

A triangle list without primitive restart whose pixel shader emulates
barycentrics draws through the generated tessellation stages when the
device has tessellation but no geometry shaders, as on MoltenVK. The
pipeline uses a three-point patch list for it, keeps it out of pipeline
libraries and validates the generated stages' modes and interface.

 - [Mesh shader grid size](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - every mesh shader loads `NumWorkgroups.x` and declares no vertices when it is 0, which no dispatch produces. The read is a workaround for RADV (Mesa 26.2.4, seen on an RX 9070 XT, GFX12): binding a mesh pipeline whose shader reads neither `NumWorkgroups` nor `DrawIndex` keeps the user SGPR count and draw-id flag of the vertex pipeline bound before it in the same command buffer (`radv_bind_pre_rast_shader` updates them only when the shader has the `AC_UD_VS_BASE_VERTEX_START_INSTANCE` slot), so `radv_emit_userdata_mesh` opens a 3-register `SET_SH_REG` and writes one value, the CP takes the following `DISPATCH_MESH_DIRECT` as register data and the GPU hangs (gfx ring timeout, MODE1 reset). Kena: Bridge of Spirits (PPSA01802) hits it on its layered volume draws. Reading `NumWorkgroups` gives every mesh shader the grid-size slot, so the count and the values match; drop the read once a fixed Mesa is the minimum
 - [Shader recompilation](../../../core/shader/recompiler/Recompiler.cpp) currently occurs right before it was transferred to Vulkan with caching, but should be moved to the [relinker](../../../core/relinker/main.cpp) stage. For this purpose, [shader/recompiler](../../../core/shader/recompiler) was written completely independently from [libs/prx](../../../core/libs/prx).
 - [v_interp_p1ll_f16, v_interp_p1lv_f16 and v_interp_p2_f16](../../../core/shader/recompiler/Translation/src/AttributeInstructions.cpp) read the 16-bit halves of each vertex's parameter through `VK_KHR_fragment_shader_barycentric` and throw without it, as fixed-function interpolation cannot split a 32-bit attribute. P10 and P20 are the vertex differences rounded to f16 to nearest even, which is not confirmed on hardware. v_interp_p1ll_f16 and v_interp_p1lv_f16 round the exact `P10 * I + P0` once to f32 and v_interp_p2_f16 rounds the exact `P20 * J + S2` once to f16, as measured on RDNA2 (#697); the exact sums are computed in f64, so these instructions need the Float64 capability. They follow the shader's float mode, measured on RDNA2 (gfx1035) in all eight combinations of `IEEE_MODE` and kept/flushed f32 and f16 denormals over 768 special and 1,024 random rows. With IEEE=1 a NaN operand is returned quieted; with IEEE=0 it is returned unquieted, except that v_interp_p2_f16's f16 result is always quiet. Flushed f32 denormals flush I/J, v_interp_p2_f16's f32 S2 and the f32 result; flushed f16 denormals flush P0, P10/P20, v_interp_p1lv_f16's f16 S2 and the f16 result. Denormal modes 1 and 2 (flush only inputs or only outputs) and rounding other than to nearest even are not measured and throw. An unknown mode follows IEEE=0 with denormals kept. Lavapipe has no barycentrics, so the draw test is skipped in CI; `agc_driver_interpolation_modes` checks the arithmetic in every mode against the hardware rows on any device with Float64.
-- Without `VK_KHR_fragment_shader_barycentric`, a pixel shader whose I/J VGPRs [only feed `v_interp_p1_f32`/`v_interp_p2_f32` of their own pair](../../../core/shader/recompiler/Optimization/src/HostInterpolationChecker.cpp) reads the attribute Vulkan interpolated. Any other read of them or of a raw vertex parameter takes the weights and the three vertex values from a [generated geometry stage](../../../core/shader/recompiler/SpirvBackend/src/BarycentricGeometryShader.cpp), which needs `geometryShader` and a vertex shader before it: tessellation, mesh and rect-list pipelines, primitives other than triangles, more than 32 fragment input locations and interfaces beyond the device's geometry limits throw.

Any other read of them or of a raw vertex parameter takes the weights and the three vertex values from a [generated geometry stage](../../../core/shader/recompiler/SpirvBackend/src/BarycentricGeometryShader.cpp), which needs `geometryShader` and a vertex shader before it. On a device with `tessellationShader` but no `geometryShader` (MoltenVK), a triangle list without primitive restart takes them from [generated tessellation stages](../../../core/shader/recompiler/SpirvBackend/src/BarycentricGeometryShader.cpp) instead: each triangle is one three-point patch at tessellation level 1, the evaluation stage writes the corner `gl_TessCoord` points at as the weights, and the vertex clip distances are forwarded. A flat parameter takes the first vertex's value there, as the geometry stage's strip gives it; the last provoking vertex throws. The patch keeps the triangle's facing with `VertexOrderCw`, checked with face culling on MoltenVK 1.4.2 (Apple M2) only. Tessellation, mesh and rect-list pipelines, primitives other than triangles, triangle strips and fans without `geometryShader`, more than 32 fragment input locations and interfaces beyond the device's geometry or tessellation limits throw.
 - [v_fma_f64 and v_div_fmas_f64](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterFloat64.cpp) with a subnormal operand or result round once, as IEEE 754 fusedMultiplyAdd does with f64 denormals kept, measured on RDNA2 (gfx1035) at IEEE=0 and IEEE=1, `v_div_fmas_f64` with VCC clear and set. The f16/f64 denormal field of `FLOAT_MODE` (bits 7:6) is not read: when it flushes, the hardware flushes the operands and the result of `v_fma_f64` (tininess before rounding) and only the result of `v_div_fmas_f64`, while these keep them. Shaders with f64 instructions declare `DenormPreserve` for 64-bit floats only when `shaderDenormPreserveFloat64` is true and Vulkan reports `denormBehaviorIndependence` as `ALL`; other independence modes are not handled by the current backend because they require coupled execution modes. See [VkShaderFloatControlsIndependence](https://docs.vulkan.org/refpages/latest/refpages/source/VkShaderFloatControlsIndependence.html). Elsewhere (including lavapipe), the driver may flush f64 subnormals, and `agc_driver_f64_fma_subnormals` is skipped.
 - [SINT storage images](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) of 8- and 16-bit components saturate each stored 32-bit value to the component range, as adriadam10 measured for image stores on RDNA2 (gfx1035) in #944 (448 rows match); the PS5's gfx1013 is not measured. A D16 store sign-extends each 16-bit half before that saturation, as measured on RDNA2 (gfx1035) for `image_store d16` to all eight SINT formats with DMASK 0xf, 0x7, 0x5, 0x3, 0x2, 0xa and 0x1 (1792 rows match).
 - [`StoreTexel`](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) writes channel 1 of a two-channel format from the data slot whose DST_SEL is Y, for SINT and UINT alike. With DST_SEL X,Y,Z,W, gfx1035 writes it from the W slot, as adriadam10 measured in #944.

 - [FORCE_DEGAMMA on RGBA8_UINT](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) materializes a direct image sampled only by plain biased pixel accesses as RGBA8_SRGB when every paired sampler forces degamma. Measured on AMD integrated RDNA2 gfx1036 (driver 32.0.21036.18, Windows 11, wave32, IEEE off, DX10 clamp on, denormals preserved, round to nearest even, FP16 overflow off): a native `image_sample_b` DIM 2D on a 16x16x1 RGBA8_UINT 3D T# returns integer channels without the bit, but the same floating-point decoded values as RGBA8_UNORM with it, including point min/max reduction and the title's exact sampler. The metadata and image view must both become floating-point sRGB; ignoring the sampler bit or retaining a UINT heap is incorrect. The accepted case requires one slice, mip zero, normalized point sampling and uniform FORCE_DEGAMMA across its samplers. Other image accesses, mixed sampler states, indirect descriptors and other integer formats remain refused. Wave64, other filtering modes and the PS5's gfx1013 are not measured.
 - The [s_swappc_b64 fetch-shader call at vertex/local/tessellation/mesh entry](../../../core/shader/recompiler/ControlFlow/src/GraphBuilder.cpp) assumes the called fetch-shader blob ends in `s_setpc_b64` to the link pair (the GNM fetch-shader shape shadPS4's `EmitFetch` copies); the blob is not part of the shader program, so its return closes the pairing by assumption and any in-program reader of the link pair throws. Attribute fetches are inlined from the request's parsed fetch-shader plan through the same `GetAttribute` path as the embedded fetch analyzer, honoring the buffer resource `dst_sel`; an attribute writing more than four registers, or an entry call without a parsed plan, throws. The vertex/instance offset accumulator inside the fetch blob is not replayed for external blobs.
 - The scalar aperture sources [src_shared_base, src_shared_limit, src_private_base, src_private_limit](../../../core/shader/recompiler/RdnaDecoder/src/RdnaInstructionDecoder.cpp) (core/shader/recompiler, scalar source codes 235 to 238) read as the 64-bit apertures the flat routing uses: a base is the aperture's high dword (`SharedApertureHigh`, `PrivateApertureHigh`) over a low dword of 0, a limit is the same high dword over 0xffffffff. A 64-bit read (`s_mov_b64`, a 64-bit VALU source, a wave64 lane mask) gets the whole value and a 32-bit read gets the low dword. This follows LLVM's `SIRegisterInfo.td` (aperture registers are 64-bit, their low 32 bits are always 0 for a base and -1 for a limit) and `getSegmentAperture` (`AMDGPULegalizerInfo.cpp`, `SIISelLowering.cpp`: a 64-bit read whose high half is the aperture), the KFD's `MAKE_LDS_APP_LIMIT` (limit = base | 0xffffffff) and the gfx1030 and gfx1035 readouts on [#1190](https://github.com/boykopovar/AnyPS5/pull/1190) and [#3803](https://github.com/boykopovar/AnyPS5/issues/3803). Not measured on a console: the PS5's high dwords are the inferred values of the flat aperture bases entry, and the wave is taken to be in 64-bit address mode (PTR32 clear)
-- [EmitSetAttribute](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - a primitive with a vertex whose clip position is (0,0,0,0) is clipped away through an extra `gl_ClipDistance` element on vertex and tessellation evaluation shaders, matching what a Radeon 610M (RDNA2, RADV) and llvmpipe rasterise; NVIDIA 615.78.08 without it draws the vertex at the viewport centre. Measured for triangles (strip and list) and for a point at (0,0,0,0), which the Radeon 610M does not draw, NVIDIA draws at the viewport centre and llvmpipe at the top-left corner; lines with such a vertex are clipped by the same element and were not measured. Mesh, geometry and the generated rect-list and barycentric stages do not write it, a device without `shaderClipDistance` cannot compile vertex shaders (the compile throws), and guest clip distances are still refused by the pipeline validator. The PS5 rasteriser was not measured.

The PS5 rasteriser was not measured.
 - [PERSP_SAMPLE and LINEAR_SAMPLE](../../../core/shader/recompiler/Translation/src/InstructionTranslator.cpp) (recompiler) hold the pixel-centre barycentrics, like the centroid pairs. With one sample this is the sample position ([Vulkan standard sample locations](https://docs.vulkan.org/spec/latest/chapters/primsrast.html#primsrast-multisampling): (0.5, 0.5)); with more samples the console's per-sample weights are not computed and were not measured.
 - [LINE_STIPPLE_TEX](../../../core/shader/recompiler/Translation/src/InstructionTranslator.cpp) (recompiler) reads as 0: line stipple is not emulated. RADV enables the input only as the required pixel input of a shader that reads no interpolants, because it initializes the fewest VGPRs ([Mesa](https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/amd/vulkan/radv_shader.c) `radv_compute_spi_ps_input`), and never reads it
 - [Static scalar calls](../../../core/shader/recompiler/ControlFlow/src/GraphBuilder.cpp) (`s_call_b64` and `s_swappc_b64`) require an ordinary even-aligned SGPR link pair (s0:s1 through s104:s105) and a later `s_setpc_b64` return reading that exact pair. A pair serves one call, or several calls whose regions are disjoint, each closed by the first return reading the pair after its target. Outside every region of its calls the pair is free to use wherever no return address can reach: a dataflow over the decoded instructions follows each dword of the pair from the calls that write it until a scalar load, SALU or VALU result is known to overwrite it (a VALU mask counts as one SGPR unless the request says wave64), and an instruction there that may read a dword still holding a return address throws; SOPC compares are exempt, as they only set SCC. Regions must nest or be disjoint; recursion, other shared links, escaping link values (including overlapping tuples and resource descriptors), invalid targets, interleaved regions, cross-region branches or fall-through, relative SGPR reads and dynamic `s_setpc_b64` in a program with calls throw. The analysis checks all decoded instructions, including unreachable code. Arbitrary indirect calls and general call frames are not implemented.

 - [Registration preparation at submit](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Queues/Submission.cpp) (libSceAgcDriver) - `Driver::Submit` waits for every registration-time shader preparation queued before the call, not only those of the shaders the commands use, so a submission behind a long queue of unrelated preparations waits for all of them on the submitting thread. Waiting there instead of in the queue worker keeps the GPU side of a submission short: a title that sees a submission take seconds treats the GPU as hung (Goat Simulator 3, PPSA04159, then stops submitting and its garbage collector fails a 10 s timeout). On the console shaders are compiled ahead of time, so neither wait exists; how long a title tolerates a slow submit call is not known.
 - [Unclamped normalized color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - CB_COLOR_INFO targets with BLEND_CLAMP clear (bit 15) on UNORM and SNORM formats are accepted when blending is disabled (ENABLE clear or BLEND_BYPASS set). Vulkan converts unblended shader values and clamps to the normalized range automatically; blending into an unclamped normalized target remains unmodeled because Vulkan always clamps inputs prior to blending.
 
+- [Thick SW_4KB_S_X volumes](../../../core/libs/prx/libSceAgcDriver/Graphics/src/TextureTiling.cpp) use AMD addrlib's GFX10 non-RB+ 16-pipe `GFX10_SW_4K_S3_X_PATINFO` equations for 1, 2, 4, 8 and 16-byte elements, including packed mip tails. The layout follows [AMD PAL c5e80007](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp); it has not been measured on console hardware. Other thick swizzle modes outside the supported families still throw. Mipmapped 3D color targets remain refused by the color-register decoder.

 - [AMPR WriteAddressFromCounterPairOnCompletion](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - the pair of an even counter n is assumed to give counter n in the low 32 bits and n + 1 in the high 32 bits. Wait compare values, wait flush and counter index ranges follow the [ampr_emu](https://github.com/drakmor/ampr_emu) reimplementation; the flush is accepted and has no effect, as commands run in order
 - [AMPR command buffer offsets](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - recording with a current offset greater than the bound memory size throws before calculating remaining capacity or writing a command. This validates the emulator's own command-buffer encoding; the console's response to a corrupted opaque buffer object is unknown.
-- [AMPR command sizes](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - commands use the emulator's own encoding with an 8-byte header, so `Nop(n)` takes 8 + 4n bytes where the console record is n dwords including its header (`NopWithData(n)`: (n + 1) dwords). The measure functions agree with the appended sizes, but a title that pads to an exact offset or the end of the buffer with `Nop(remaining / 4)` gets `SCE_AMPR_ERROR_BUFFER_FULL` or a shifted offset. The at-start flag of the `_04_00` writes is ignored; commands run in order, each after the previous one completes

 - [APR map begin and end](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - as in ampr_emu, `MapBegin`/`MapDirectBegin` map when they run and `MapEnd` only closes the region; while a region is open a second begin and every completion write return `EPERM`, the at-start `_04_00` writes are accepted
 - [AMPR markers](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - signatures taken from the [ampr_emu](https://github.com/drakmor/ampr_emu) reimplementation, not confirmed on a title: `sceAmprCommandBufferSetMarkerWithColor` takes the color by pointer, the push and measure variants by value. Colors are not recorded
 - [__cxa_call_unexpected](../../../core/libs/prx/libSceAmpr/Export.cpp) (libSceAmpr) - takes the in-flight exception's unwind header and never returns, as [libcxxabi 18.1.8](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_personality.cpp#L1171-L1211) does. No `std::set_unexpected` is exported and the exception header's unexpected handler is never set, so the handler is always the default one, which calls `std::terminate` ([cxa_default_handlers.cpp](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_default_handlers.cpp#L88-L99)); it therefore forwards to libc's `__cxa_call_terminate`, which begins the catch and runs the current terminate handler. That matches libcxxabi except for which terminate handler runs: there `std::terminate` after `__cxa_begin_catch` ([cxa_exception.cpp L470-L477](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_exception.cpp#L470-L477)) runs the handler saved in the caught exception's header ([cxa_handlers.cpp L72-L93](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_handlers.cpp#L72-L93)), which `__cxa_throw` and `__cxa_init_primary_exception` set to `std::get_terminate()` when the exception is thrown ([cxa_exception.cpp L209-L214](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_exception.cpp#L209-L214), [L279](https://github.com/llvm/llvm-project/blob/3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff/libcxxabi/src/cxa_exception.cpp#L279)), while here the current global handler runs, as AnyPS5's own `std::terminate` does. The two differ only if `std::set_terminate` was called between the throw and this call. A null header terminates because this emulator's libc `__cxa_begin_catch` terminates on null (libcxxabi does not define that case). Dynamic exception specifications that would let a replaced unexpected handler throw a permitted type are not modelled

Subject: [PATCH 0887/1000] fix(relinker): move a neighbour without an FS or GS
 prefix with a 256-bit store first

A 256-bit store is 4 bytes, so its stub window takes a neighbouring
instruction to make room for the jump. The window took the following
instruction first even when it was a guest TLS access (an FS or GS prefix).
The macOS writer cannot rewrite a TLS access inside a stub and refuses the
module with "AMD-only instruction is also a guest TLS access".

The window now tries the following and the preceding instruction without a
segment prefix first, and falls back to the old order only when neither
works, so outputs that can keep the access in the stub do not change.

Subject: [PATCH 0889/1000] ci(intake): let a maintainer reopen bypass the
 open-PR limit

The intake workflow re-closes a reopened PR whose author is still over the
open-PR limit, so a maintainer cannot rescue PRs it auto-closed. When the
reopening actor has write, maintain or admin permission, skip the limit and
remove the "open PR limit" label instead. Contributor reopens behave as
before, and if the permission lookup fails the limit still applies.

Subject: [PATCH 0890/1000] feat(libkernel): poll regular files and directories
 as vop_stdpoll does

poll threw for any descriptor that is neither a socket nor a pipe, so a title polling a file it also reads stopped there. FreeBSD 11.4 hands a vnode to VOP_POLL, and both vop_stdpoll and vop_nopoll return POLLIN, POLLRDNORM and POLLOUT of the requested events for every event poll accepts and never POLLPRI, POLLRDBAND or POLLWRBAND. A file, a directory or a file read from app0.zar now answers that without a host call. File::IsVnode tells such a descriptor apart from the host file type without throwing, so a host socket lent by libSceNet still reaches its own path.

 - [read, write and vector I/O](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on a guest socket use `recv` and `send` without flags; `sceKernelReadv` and `sceKernelWritev` gather or scatter through one socket operation, preserving stream short reads and datagram boundaries. The positioned `pread`, `pwrite`, `preadv` and `pwritev` forms, and their `sceKernel` forms, return `ESPIPE` for an open guest socket and `EBADF` for a closed one. `EPIPE` from a write raises the host's `SIGPIPE` on Linux unless the socket has `SO_NOSIGPIPE` set, and the guest cannot ignore it: `signal(SIGPIPE, SIG_IGN)` and `sigaction` record the disposition, as they do for every number from 1 to 128, but only the six signals with host equivalents (2, 4, 6, 8, 11 and 15) take effect on the host or are delivered, so the host `SIGPIPE` is not stopped; nothing is raised on Windows; a `write` longer than `INT_MAX` bytes is `EMSGSIZE` where the console sends it. AIO on a guest socket still goes to the host, which has no such descriptor
 - [Socket descriptor numbers](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel, libSceNet) - `socket`, `accept`, `socketpair`, `dup`, `sceNetSocket` and `sceNetAccept` take the lowest free number of the host descriptor table that files use, as FreeBSD 11.4 `fdalloc` takes the lowest free entry of the one process table (`kern_descrip.c`), so every number stays below `FD_SETSIZE` (1024) while fewer than 1024 descriptors are open. The number holds a zero-access `NUL` handle on Windows and a duplicate of the host socket on Linux, and the socket tables map it to the socket. The host table also holds the runtime's own files, so the numbers differ from the console's; the first number `socket` and `sceNetSocket` return on a console and its `getdtablesize` are not measured. Paths that bypass the socket tables see the placeholder: libc `fdopen` on a socket opens it, and libkernel `close` of a libSceNet socket releases the number but leaves the libSceNet socket open. Palworld (PPSA23126), The Mound (PPSA26223) and Dying Light 2 (PPSA02262) set socket bits in a 1024-bit `fd_set`
 - [fstat on a guest socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) fills the fields FreeBSD 11's soo_stat and pru_sense_null fill and zeroes the rest: S_IFSOCK, the read bits while the receive side is open or data is queued, the write bits while the send side is open, st_size and st_blksize. Only this process's shutdown closes a side here; a peer's shutdown, close or reset does not clear the bits as FreeBSD's socantrcvmore and socantsendmore do. st_size is the host's FIONREAD, which for a Linux datagram socket is the size of the next datagram where FreeBSD counts every queued byte, and st_blksize is the host's SO_SNDBUF, which Linux reports as twice the size that was set. A socketpair end reports st_dev and st_ino 0, where FreeBSD's uipc_sense reports NODEV and a per-socket number
-- [poll](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) waits on guest sockets and pipes, through `WSAPoll` on Windows and `poll` on Linux; the `pollfd` layout and flag values are FreeBSD's. A libSceNet socket joins the same host wait through the native socket libSceNet lends to libkernel. `WSAPoll` rejects `POLLPRI`, so on Windows a socket's `POLLPRI` is asked as `POLLRDBAND` and `POLLIN` as `POLLRDNORM`; Winsock reports urgent data until it is read with `MSG_OOB`, where FreeBSD 11.4's `sopoll_generic` stops once the normal stream passes the mark. Guest `send` and `recv` refuse `MSG_OOB` with `EOPNOTSUPP`, so urgent data can only come from an outside peer and Windows keeps reporting `POLLPRI` after the stream passes the mark. A pipe follows FreeBSD's `pipe_poll`: the read end is readable when data is buffered, either end reports `POLLHUP` once the other end is closed, with the requested `POLLIN` and `POLLRDNORM` bits and without `POLLOUT`, which `pollscan` clears, and the write end is writable when `PIPE_BUF` (512) bytes are free on Windows, or when the host kernel says so on Linux. `POLLOUT` on a read end throws: FreeBSD opens both ends for reading and writing and reports it writable, and host pipes are one-way. Windows pipes cannot be waited on, so while a pipe is polled `poll` checks it with `NtQueryInformationFile` and waits on the sockets in slices of 1 ms. A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket nor a pipe (files, stdio) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on. A closed socket descriptor reports `POLLNVAL`; the console's limit on the descriptor count is unknown and not checked

Windows pipes cannot be waited on, so while a pipe is polled `poll` checks it with `NtQueryInformationFile` and waits on the sockets in slices of 1 ms. A regular file, a directory or a file read from app0.zar is always ready for `POLLIN`, `POLLRDNORM` and `POLLOUT` and never for `POLLPRI`, `POLLRDBAND` or `POLLWRBAND`, as FreeBSD 11.4's [`vop_stdpoll`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/vfs_default.c#L563-L574) and `vop_nopoll` answer every event `poll` accepts; which of the two the console's filesystems use is not known, and they agree on these events. A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket, a pipe, a file nor a directory (stdio, devices) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on.

 - [kevent on a pipe](../../../core/libs/prx/libkernel/Equeue/src/Kqueue.cpp) (libkernel) - `EVFILT_READ` on the read end of a pipe follows FreeBSD 11's [`filt_piperead`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/sys_pipe.c#L1787-L1806): `data` is the number of buffered bytes, and `EV_EOF` is set once the write end is closed. Windows pipes cannot be waited on, so while a kqueue waits on a pipe it checks it with `NtQueryInformationFile` and waits on its sockets in slices of 1 ms; a wait with no pipe is not sliced. `EVFILT_READ` on the write end of a pipe throws: FreeBSD's `pipe` opens both ends for reading and writing ([`kern_pipe`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/sys_pipe.c#L422)), and host pipes are one-way. `EVFILT_WRITE` on a pipe throws too, and `NOTE_LOWAT` on a pipe is ignored, as `filt_piperead` ignores it.
 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
 - [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.

Subject: [PATCH 0891/1000] feat(libkernel): poll the random device as
 randomdev_poll does

poll threw for /dev/random and /dev/urandom, which select already treats as ready. FreeBSD 11.4's randomdev_poll, once the device is seeded, narrows a request that has POLLIN or POLLRDNORM to those bits and returns any other request whole, POLLOUT and the band bits included. poll now answers that, and the test that relied on the random device throwing uses a kqueue descriptor, which poll still does not support.

 - [read, write and vector I/O](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on a guest socket use `recv` and `send` without flags; `sceKernelReadv` and `sceKernelWritev` gather or scatter through one socket operation, preserving stream short reads and datagram boundaries. The positioned `pread`, `pwrite`, `preadv` and `pwritev` forms, and their `sceKernel` forms, return `ESPIPE` for an open guest socket and `EBADF` for a closed one. `EPIPE` from a write raises the host's `SIGPIPE` on Linux unless the socket has `SO_NOSIGPIPE` set, and the guest cannot ignore it: `signal(SIGPIPE, SIG_IGN)` and `sigaction` record the disposition, as they do for every number from 1 to 128, but only the six signals with host equivalents (2, 4, 6, 8, 11 and 15) take effect on the host or are delivered, so the host `SIGPIPE` is not stopped; nothing is raised on Windows; a `write` longer than `INT_MAX` bytes is `EMSGSIZE` where the console sends it. AIO on a guest socket still goes to the host, which has no such descriptor
 - [Socket descriptor numbers](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel, libSceNet) - `socket`, `accept`, `socketpair`, `dup`, `sceNetSocket` and `sceNetAccept` take the lowest free number of the host descriptor table that files use, as FreeBSD 11.4 `fdalloc` takes the lowest free entry of the one process table (`kern_descrip.c`), so every number stays below `FD_SETSIZE` (1024) while fewer than 1024 descriptors are open. The number holds a zero-access `NUL` handle on Windows and a duplicate of the host socket on Linux, and the socket tables map it to the socket. The host table also holds the runtime's own files, so the numbers differ from the console's; the first number `socket` and `sceNetSocket` return on a console and its `getdtablesize` are not measured. Paths that bypass the socket tables see the placeholder: libc `fdopen` on a socket opens it, and libkernel `close` of a libSceNet socket releases the number but leaves the libSceNet socket open. Palworld (PPSA23126), The Mound (PPSA26223) and Dying Light 2 (PPSA02262) set socket bits in a 1024-bit `fd_set`
 - [fstat on a guest socket](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) fills the fields FreeBSD 11's soo_stat and pru_sense_null fill and zeroes the rest: S_IFSOCK, the read bits while the receive side is open or data is queued, the write bits while the send side is open, st_size and st_blksize. Only this process's shutdown closes a side here; a peer's shutdown, close or reset does not clear the bits as FreeBSD's socantrcvmore and socantsendmore do. st_size is the host's FIONREAD, which for a Linux datagram socket is the size of the next datagram where FreeBSD counts every queued byte, and st_blksize is the host's SO_SNDBUF, which Linux reports as twice the size that was set. A socketpair end reports st_dev and st_ino 0, where FreeBSD's uipc_sense reports NODEV and a per-socket number
-- [poll](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) waits on guest sockets and pipes, through `WSAPoll` on Windows and `poll` on Linux; the `pollfd` layout and flag values are FreeBSD's. A libSceNet socket joins the same host wait through the native socket libSceNet lends to libkernel. `WSAPoll` rejects `POLLPRI`, so on Windows a socket's `POLLPRI` is asked as `POLLRDBAND` and `POLLIN` as `POLLRDNORM`; Winsock reports urgent data until it is read with `MSG_OOB`, where FreeBSD 11.4's `sopoll_generic` stops once the normal stream passes the mark. Guest `send` and `recv` refuse `MSG_OOB` with `EOPNOTSUPP`, so urgent data can only come from an outside peer and Windows keeps reporting `POLLPRI` after the stream passes the mark. A pipe follows FreeBSD's `pipe_poll`: the read end is readable when data is buffered, either end reports `POLLHUP` once the other end is closed, with the requested `POLLIN` and `POLLRDNORM` bits and without `POLLOUT`, which `pollscan` clears, and the write end is writable when `PIPE_BUF` (512) bytes are free on Windows, or when the host kernel says so on Linux. `POLLOUT` on a read end throws: FreeBSD opens both ends for reading and writing and reports it writable, and host pipes are one-way. Windows pipes cannot be waited on, so while a pipe is polled `poll` checks it with `NtQueryInformationFile` and waits on the sockets in slices of 1 ms. A regular file, a directory or a file read from app0.zar is always ready for `POLLIN`, `POLLRDNORM` and `POLLOUT` and never for `POLLPRI`, `POLLRDBAND` or `POLLWRBAND`, as FreeBSD 11.4's [`vop_stdpoll`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/vfs_default.c#L563-L574) and `vop_nopoll` answer every event `poll` accepts; which of the two the console's filesystems use is not known, and they agree on these events. A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket, a pipe, a file nor a directory (stdio, devices) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on. A closed socket descriptor reports `POLLNVAL`; the console's limit on the descriptor count is unknown and not checked

A closed descriptor reports `POLLNVAL`, and an open descriptor that is neither a guest socket, a libSceNet socket, a pipe, a file, a directory nor the random device (stdio, other devices) throws, as do event bits other than `POLLIN`, `POLLPRI`, `POLLOUT`, `POLLRDNORM`, `POLLRDBAND` and `POLLWRBAND` (the `POLLERR`, `POLLHUP` and `POLLNVAL` bits are ignored in `events`), an infinite timeout with no socket or pipe to wait on.

 - [kevent on a pipe](../../../core/libs/prx/libkernel/Equeue/src/Kqueue.cpp) (libkernel) - `EVFILT_READ` on the read end of a pipe follows FreeBSD 11's [`filt_piperead`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/sys_pipe.c#L1787-L1806): `data` is the number of buffered bytes, and `EV_EOF` is set once the write end is closed. Windows pipes cannot be waited on, so while a kqueue waits on a pipe it checks it with `NtQueryInformationFile` and waits on its sockets in slices of 1 ms; a wait with no pipe is not sliced. `EVFILT_READ` on the write end of a pipe throws: FreeBSD's `pipe` opens both ends for reading and writing ([`kern_pipe`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/sys_pipe.c#L422)), and host pipes are one-way. `EVFILT_WRITE` on a pipe throws too, and `NOTE_LOWAT` on a pipe is ignored, as `filt_piperead` ignores it.
 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
 - [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.

Subject: [PATCH 0892/1000] fix(libkernel): answer select on files and the
 random device as FreeBSD's poll routines do

selscan asks a descriptor once, with the flags of every set it is in (POLLRDNORM for the read set, POLLWRNORM for the write set, POLLRDBAND for the exception set, plus POLLHUP and POLLERR), and marks each set whose flags the answer shares. A seeded random device's randomdev_poll narrows a request with POLLRDNORM to that bit and returns any other request whole, so in the read set it is readable and in no other set, and otherwise it is in each write and exception set it was asked in; select reported it readable and writable together and never exceptional. A regular file or directory went to the host poll, which on Windows threw; vop_stdpoll makes it readable and writable and never exceptional, which select now answers in process on every host, as poll does.

 - [Mapping hints with no room above them](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) (libkernel) - a mapping without `MAP_FIXED` whose hint lies above the guest address space, or has no free range at or above it, is placed from the bottom of the guest arena, as FreeBSD 11.4's [`vm_mmap_object`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/vm/vm_mmap.c#L1569) retries through [`vm_map_find_min`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/vm/vm_map.c#L1555-L1584) from its minimum address. FreeBSD's minimum is the end of the largest possible data segment rather than the start of the arena, and the console's address-space layout is not measured. PS5CEMU-HAR (PPSA99360) gives `sceKernelReserveVirtualRange` a hint near its own code, which is a host address here because the relinked executable lies outside the guest arena, so its JIT gets memory more than 2 GiB from its code and does not start
 - [_sceKernelRtldThreadAtexitIncrement, _sceKernelRtldThreadAtexitDecrement](../../../core/libs/prx/libkernel/System/src/Rtld.cpp) (libkernel) - the argument is the `dso` address a title's `libc.prx` passes to `__cxa_thread_atexit` (PPSA14632), which fails when Increment returns nonzero. As in the [fpPS4](https://github.com/red-prig/fpPS4) reimplementation, Increment takes a reference on the loaded image containing the address and Decrement releases one; the variants without the leading underscore are assumed to match
 - [tcgetattr, tcsetattr](../../../core/libs/prx/libkernel/File/src/Terminal.cpp) (libkernel) - every file and pipe descriptor is taken as not a terminal (`ENOTTY`), and a socket gets `EADDRNOTAVAIL` for `AF_INET` and `EOPNOTSUPP` otherwise, as FreeBSD's `in_control` and `pru_control_notsupp` answer a termios ioctl; what descriptors 0 to 2 of a title are on the console, and whether any of them is a terminal there, is unknown
-- [select](../../../core/libs/prx/libkernel/Socket/src/Socket.cpp) (libkernel) - descriptor 0 is never reported readable and descriptors 1 and 2 are always writable, as for a console title with no input; reads from descriptor 0 still go to the host stdin. `/dev/random` and `/dev/urandom` are always readable and writable, as FreeBSD reports a seeded random device.

Subject: [PATCH 0893/1000] feat(libkernel): poll descriptors 0 to 2 with the
 console model select uses

select takes descriptors 0 to 2 as a console title's terminal with no input: 0 is never readable and 1 and 2 are always writable. poll threw for them unless the host happened to attach a pipe, so the same title could select on its standard streams but not poll them. poll now gives the same answer, with POLLOUT, the one bit ttydev_poll reports for a writable terminal, for 1 and 2 and nothing for 0.

 - [read, write and vector I/O](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on a guest socket use `recv` and `send` without flags; `sceKernelReadv` and `sceKernelWritev` gather or scatter through one socket operation, preserving stream short reads and datagram boundaries. The positioned `pread`, `pwrite`, `preadv` and `pwritev` forms, and their `sceKernel` forms, return `ESPIPE` for an open guest socket and `EBADF` for a closed one. `EPIPE` from a write raises the host's `SIGPIPE` on Linux unless the socket has `SO_NOSIGPIPE` set, and the guest cannot ignore it: `signal(SIGPIPE, SIG_IGN)` and `sigaction` record the disposition, as they do for every number from 1 to 128, but only the six signals with host equivalents (2, 4, 6, 8, 11 and 15) take effect on the host or are delivered, so the host `SIGPIPE` is not stopped; nothing is raised on Windows; a `write` longer than `INT_MAX` bytes is `EMSGSIZE` where the console sends it. AIO on a guest socket still goes to the host, which has no such descriptor
 - [Socket descriptor numbers](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel, libSceNet) - `socket`, `accept`, `socketpair`, `dup`, `sceNetSocket` and `sceNetAccept` take the lowest free number of the host descriptor table that files use, as FreeBSD 11.4 `fdalloc` takes the lowest free entry of the one process table (`kern_descrip.c`), so every number stays below `FD_SETSIZE` (1024) while fewer than 1024 descriptors are open. The number holds a zero-access `NUL` handle on Windows and a duplicate of the host socket on Linux, and the socket tables map it to the socket. The host table also holds the runtime's own files, so the numbers differ from the console's; the first number `socket` and `sceNetSocket` return on a console and its `getdtablesize` are not measured. Paths that bypass the socket tables see the placeholder: libc `fdopen` on a socket opens it, and libkernel `close` of a libSceNet socket releases the number but leaves the libSceNet socket open.

Only this process's shutdown closes a side here; a peer's shutdown, close or reset does not clear the bits as FreeBSD's socantrcvmore and socantsendmore do. st_size is the host's FIONREAD, which for a Linux datagram socket is the size of the next datagram where FreeBSD counts every queued byte, and st_blksize is the host's SO_SNDBUF, which Linux reports as twice the size that was set.

Guest `send` and `recv` refuse `MSG_OOB` with `EOPNOTSUPP`, so urgent data can only come from an outside peer and Windows keeps reporting `POLLPRI` after the stream passes the mark.

Windows pipes cannot be waited on, so while a kqueue waits on a pipe it checks it with `NtQueryInformationFile` and waits on its sockets in slices of 1 ms; a wait with no pipe is not sliced. `EVFILT_READ` on the write end of a pipe throws: FreeBSD's `pipe` opens both ends for reading and writing ([`kern_pipe`](https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/sys_pipe.c#L422)), and host pipes are one-way. `EVFILT_WRITE` on a pipe throws too, and `NOTE_LOWAT` on a pipe is ignored, as `filt_piperead` ignores it.
 - [Socket error numbers](../../../core/libs/prx/libkernel/Socket/include/SocketError.hpp) (libkernel) - a host socket error becomes the FreeBSD 11 `errno.h` number of the same name; the numbers are not checked on the console. Winsock `WSAESHUTDOWN` becomes `EPIPE`, as a send after `shutdown` does on FreeBSD, and a host error with no FreeBSD socket counterpart becomes `EIO`. A nonblocking `connect` in progress reports `EINPROGRESS` on Linux but `EAGAIN` on Windows (`WSAEWOULDBLOCK`), where FreeBSD reports `EINPROGRESS`. On Windows a refused nonblocking `connect` is never reported (`SO_ERROR` is unsupported), so a repeated one keeps reporting `EALREADY` where FreeBSD reports `ECONNREFUSED`. A receive after `shutdown(SHUT_RD)` reports `EPIPE` on Windows where FreeBSD returns 0
 - [getsockopt, setsockopt](../../../core/libs/prx/libkernel/Socket/src/SocketOptions.cpp) (libkernel) on a guest socket handle the SOL_SOCKET level and `TCP_NODELAY`, after FreeBSD 11.4's [`sosetopt` and `sogetopt`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c): `SO_REUSEADDR`, `SO_KEEPALIVE`, `SO_DONTROUTE`, `SO_BROADCAST`, `SO_OOBINLINE` and `SO_LINGER` act on the host socket, and `SO_ERROR`, `SO_TYPE`, `SO_ACCEPTCONN`, `SO_SNDBUF` and `SO_RCVBUF` are read. A boolean option reads back as its own bit, as FreeBSD returns `so_options & option`. Winsock does not clear a socket's pending error when it is read, so on Windows the library reports a pending error once and shows it again only after a new `connect`; a second failure with the same code on the same socket without a `connect` in between would be hidden. `SO_SNDBUF` and `SO_RCVBUF` read the host's value, which is not the size FreeBSD reports (Linux doubles it). `SO_NOSIGPIPE` is kept per socket and reads back as its bit. On Linux a `send`, `sendto`, `sendmsg` or `write` on that socket passes `MSG_NOSIGNAL` to the host, as [`kern_sendit`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L890-L895) and [`soo_write`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/sys_socket.c#L147-L151) leave out the signal. An accepted socket takes it from its listener, as [`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L603) copies the options. `SO_NBIO` (`0x1200`) is the console's own option, not FreeBSD's. It switches the socket between blocking and non-blocking as `FIONBIO` does and reads back as 0 or 1, as `sceNetSetsockopt` and `sceNetGetsockopt` treat it here; what the console reads back for it is not measured. `TCP_NODELAY` (`IPPROTO_TCP`, 1) is set on the host socket and reads back as `TF_NODELAY` (4), as [`tcp_default_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/tcp_usrreq.c#L1860-L1861) returns it. The `IPPROTO_TCP` level on a datagram or `AF_UNIX` socket fails with `EINVAL`, as [`ip_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/netinet/ip_output.c#L943-L944) and [`uipc_ctloutput`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_usrreq.c#L1228-L1229) answer it, and an accepted socket takes `TCP_NODELAY` through the host. `SO_SNDTIMEO` and `SO_RCVTIMEO` follow [`sosetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2657-L2689) and [`sogetopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L2846-L2850). A 16-byte `timeval` with a negative field or 1000000 microseconds or more fails with `EDOM`, and more than `INT32_MAX` seconds becomes the longest wait. The value is kept and read back through FreeBSD's 32.32 fixed-point conversion ([`tvtosbt`, `sbttotv`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/sys/time.h#L178-L286)), so half a second reads back as 499999 microseconds and one microsecond as 0. A `recv`, `recvfrom`, `recvmsg`, `read` or `readv`, and a `send`, `sendto`, `sendmsg`, `write` or `writev`, on a blocking socket then waits that long for the host to report the socket readable or writable, and fails with `EWOULDBLOCK`; a call with `MSG_DONTWAIT` does not wait. An accepted socket takes both from its listener ([`sonewconn`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_socket.c#L629-L630)). The wait covers only the first transfer: once the socket is writable the host send runs without a limit, where FreeBSD stops a send that cannot finish and returns the bytes sent so far, and a receive whose data another thread takes between the wait and the host call blocks again. `sendfile` ignores the send timeout. The host wait has millisecond steps, so a shorter timeout lasts up to a millisecond longer. A null value fails with `EINVAL`, where FreeBSD's [`kern_setsockopt`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/kern/uipc_syscalls.c#L1414-L1415) returns `EFAULT`. Every other SOL_SOCKET option (`SO_DEBUG`, `SO_USELOOPBACK`, `SO_REUSEPORT` and `SO_TIMESTAMP`, which FreeBSD stores and no title has been seen to set, the low-water marks among them), every other `IPPROTO_TCP` option (`TCP_MAXSEG`, `TCP_KEEPIDLE`, `TCP_KEEPINTVL` and `TCP_KEEPCNT` among them) and every other level (`IPPROTO_IP`, `IPPROTO_IPV6`) fail with `ENOPROTOOPT`. None of this was measured on a console.

Subject: [PATCH 0894/1000] fix(libkernel): select on kqueues as kqueue_poll
 answers

A kqueue descriptor is readable while one of its events is triggered and
is never writable or exceptional, as FreeBSD's kqueue_poll answers, on
both hosts. On Windows select threw for it, and on Linux its /dev/null
placeholder was reported readable and writable.

A descriptor that stops being a socket, a kqueue or a pipe during the
wait now fails the call with EBADF when it was closed and is selected
again with the rest of the timeout when its number was reused, as
FreeBSD's kern_select looks every descriptor up again in each pass,
instead of throwing. On Windows a host descriptor that is not a pipe
throws when select starts, before waiting.

Depends on #7139.

 - [Mapping hints with no room above them](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) (libkernel) - a mapping without `MAP_FIXED` whose hint lies above the guest address space, or has no free range at or above it, is placed from the bottom of the guest arena, as FreeBSD 11.4's [`vm_mmap_object`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/vm/vm_mmap.c#L1569) retries through [`vm_map_find_min`](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/sys/vm/vm_map.c#L1555-L1584) from its minimum address. FreeBSD's minimum is the end of the largest possible data segment rather than the start of the arena, and the console's address-space layout is not measured. PS5CEMU-HAR (PPSA99360) gives `sceKernelReserveVirtualRange` a hint near its own code, which is a host address here because the relinked executable lies outside the guest arena, so its JIT gets memory more than 2 GiB from its code and does not start
 - [_sceKernelRtldThreadAtexitIncrement, _sceKernelRtldThreadAtexitDecrement](../../../core/libs/prx/libkernel/System/src/Rtld.cpp) (libkernel) - the argument is the `dso` address a title's `libc.prx` passes to `__cxa_thread_atexit` (PPSA14632), which fails when Increment returns nonzero. As in the [fpPS4](https://github.com/red-prig/fpPS4) reimplementation, Increment takes a reference on the loaded image containing the address and Decrement releases one; the variants without the leading underscore are assumed to match
 - [tcgetattr, tcsetattr](../../../core/libs/prx/libkernel/File/src/Terminal.cpp) (libkernel) - every file and pipe descriptor is taken as not a terminal (`ENOTTY`), and a socket gets `EADDRNOTAVAIL` for `AF_INET` and `EOPNOTSUPP` otherwise, as FreeBSD's `in_control` and `pru_control_notsupp` answer a termios ioctl; what descriptors 0 to 2 of a title are on the console, and whether any of them is a terminal there, is unknown
-- [select](../../../core/libs/prx/libkernel/Socket/src/Socket.cpp) (libkernel) - descriptor 0 is never reported readable and descriptors 1 and 2 are always writable, as for a console title with no input; reads from descriptor 0 still go to the host stdin. `/dev/random` and `/dev/urandom` follow `randomdev_poll` for a seeded device under [`selscan`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/sys_generic.c#L1178-L1236), which asks once with the flags of every set the descriptor is in: in the read set they are readable and reported in no other set, and otherwise they are reported in the write and exception sets they were asked in. A regular file, a directory or a file read from app0.zar is always readable and writable and never in the exception set, as `vop_stdpoll` answers, on every host. Guest sockets and libSceNet sockets are polled; other descriptors are polled through the host on Linux, while on Windows pipes are checked every millisecond with the readiness test `poll` uses and any other descriptor throws. Dungeons (PPSA16064) selects on descriptor 0, and RetroArch (PPSA99169) selects on its web server's wake-up pipe next to its listening socket
-- [select](../../../core/libs/prx/libkernel/Socket/src/Socket.cpp) (libkernel) - a descriptor the socket poller reports as unknown that is below `GuestSockets::FirstDescriptor` is polled on the host instead of throwing (on Windows only a pipe, as above); an invalid host descriptor fails with `EBADF`, and mixed host and socket sets are polled in short alternating slices so neither side waits out the full slice alone.

A descriptor that stops being a socket, a kqueue or a pipe during the wait fails the call with `EBADF` when it is closed and is selected again with the rest of the timeout when its number was reused, as FreeBSD 11.4's [`kern_select`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/sys_generic.c#L1129-L1140) looks every descriptor up again in each pass. A close that has already removed the descriptor from the guest's kqueue, pipe or file tables but not yet closed its host descriptor is seen by that new look-up as a descriptor of unknown kind, which throws on Windows and is polled through the host on Linux. Wobbly Life (PPSA29413) selects on file descriptors while streaming its bundles
 - [__progname](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - unknown data export
 - [environ](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - data export pointing to a fixed empty environment so titles that import it load; it is not the environment libc's `getenv` reads, so it lists none of those variables and `setenv`/`putenv` changes do not appear in it
 - [seteuid, setegid, setuid, setreuid, setregid, setgroups, getgroups](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) - the guest process is assumed to run as root, with real, effective and saved user and group ids 0. As in FreeBSD's `sys_seteuid`, `sys_setegid`, `sys_setuid`, `sys_setreuid` and `sys_setregid`, id 0 (or -1 for an unchanged `setreuid`/`setregid` id) is then accepted without a privilege check and changes no credential, so 0 is returned; any other id would change an id, which is not modelled, and throws. `setgroups` keeps the supplementary group list as `kern_setgroups` does (`NGROUPS_MAX` 1023, an empty list leaves the effective group as the only entry, a first entry other than 0 would change the effective group and throws) and `getgroups` reports it. The ids and privileges a title has on a console are unverified

Subject: [PATCH 0896/1000] test(agc): expect a per-lane table image store to
 be supported

Main's #6402 runs image stores through an image table, so a T# keyed
per lane keeps its table with a supported image_store and an
unsupported mark for the other operations.

Subject: [PATCH 0897/1000] fix(main): split conventions comment checks into 12
 shards

Failing run 39076267931 (push 55f82fee83): windows conventions_function_bodies_shard_4 hit the 30 s CTest timeout (others 15-26 s on the loaded runner). No culprit merge; shard cost sits near the limit since 541a4e705 (6 shards). Doubling the shard count halves each test's runtime.

Subject: [PATCH 0898/1000] fix(recompiler): fold chained immediate addends of
 image-table record offsets

SplitImmediateAddend peeled a single immediate operand off a T# dword's
scalar offset. A title that loads a 32-byte record with two
s_load_dwordx4, the second at soffset (first soffset + 16) where the
first is (key << 5) + C, left IAdd32(key << 5, C) as the base of dwords
4-7, which never matched dword 0's base, and the image failed with
"GetImageResource dword 0 is not a valid runtime value".

Peel immediate IAdd32 operands until none is left and sum them modulo
2^32, as the scalar adds do. The chained offsets then reach the existing
folded-addend path. verifyChainedTableOffset is the pointer table offset
carry shader with the second offset chained off the first.

Subject: [PATCH 0899/1000] test(tools): check shader comments in one fixture
 repository

conventions_function_bodies_shard_4 timed out at 30 s on Windows in five runs on 17 Oct (main pushes 39076267931 and 39061030084, dispatches 39074123651 and 39044676931, relinker 39072918668). Shard 4 was the slowest shard in every Windows log (10-16 s on a quiet runner, 5-11 s for the others).

One case dominated it: test_comment_in_a_shader_is_reported built six fixture git repositories, 36 of the suite's 390 processes. Process start-up is what costs on Windows. #7314 doubled the shard count, but modulo sharding keeps that case whole, so its shard (now shard 10) still cost 0.63 s of the suite's 3.0 s locally against 0.76 s before.

The case now writes all six shaders into one fixture and runs the checker once (6 processes), still asserting each path. The slowest of the 12 shards drops to 0.39 s locally (43 processes), with no timeout raised.

Subject: [PATCH 0900/1000] fix(relinker): keep test artifacts in the build
 tree

The tests build their working directories with tempfile.TemporaryDirectory()
and std::filesystem::temp_directory_path(), so every executable they generate
lands in the user's system temp directory. On Windows, Microsoft Defender
quarantines those generated binaries as Trojan:Win32/Wacatac.H!ml, and the
nine tests that run one fail with WinError 5 (access denied) on a clean
checkout: autorun_exit_status, optional_plt, empty_tls, tls_function_coverage,
executable_segments, windows_icon, guest_needed_modules,
guest_module_directories and windows_import_modules.

Point TMPDIR, TEMP and TMP at a build-local directory for every test
registered here, so generated executables stay inside the build tree. Test
artifacts are then removed with the build directory, and a contributor who
needs an antivirus exclusion can scope it to the build tree instead of the
system temp directory.

Subject: [PATCH 0901/1000] fix(libkernel): name module-relative call sites and
 thread ids in Linux wait traces

On Linux, APS5_TRACE_WAITS and APS5_TRACE_USLEEP used an image base and a thread
id of 0, so "exe+0x..." printed absolute addresses and every site reported
"tid 0". The call site is now resolved with dladdr1(RTLD_DL_LINKMAP) and printed
relative to its module's load address ("exe+..." for the executable, the module
file name otherwise), matching guest offsets in a disassembly; the thread id is
gettid(). Descriptions are cached per call site, so polling titles do not pay a
dladdr1 per wait. Windows output is unchanged.

Subject: [PATCH 0902/1000] refactor(libSceSystemService): share the console
 language setting

SystemServiceConsoleLanguage in SystemService.hpp reads ANYPS5_LANGUAGE
with the same default, range and error as sceSystemServiceParamGetInt,
which now calls it. Other libraries can pick the console language
without linking libSceSystemService.

Subject: [PATCH 0903/1000] fix(libSceNpTrophy2): give progress values a type
 and a 64-bit value

A progress value is {int32 type, 4 reserved bytes, uint64 value}, as
KytyPS5 lays it out, which makes the trophy details 1312 bytes and the
trophy data 32 bytes. Size checks for every query structure keep the
layout fixed, and the technical debt names its single public source.

 ### Unknown function info
 
+- [Query structures](../../../core/libs/prx/libSceNpTrophy2/include/NpTrophy2Types.hpp): a progress value is a 16-byte `{int32 type, 4 reserved bytes, uint64 value}` and the game, group and trophy structures are 152, 24, 152, 32, 1312 and 32 bytes, as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/9e41d8320a2774b303fbad344c2347e8d0292e83/src/libs/libTrophy.cpp) asserts; no other public source confirms the layout. Progress type 1 marks a progressive trophy's target and progress, as in KytyPS5.

 - [sceNpTrophy2GetRewardIcon](../../../core/libs/prx/libSceNpTrophy2/src/Context.cpp) (libSceNpTrophy2) takes `(int context, int handle, int reward_id, void* buffer, size_t* size)`, from the call sites in the bundled `Media/Plugins/PSNCore.prx` of PPSA06888, the same shape as `sceNpTrophy2GetTrophyIcon`. The title calls it twice: first with a null buffer to read the size, then with a buffer of that size allocated with `malloc`. The meaning of the third argument is unverified, and the reward icon data is unknown, so every call throws

Subject: [PATCH 0904/1000] feat(libSceNpTrophy2): report the title's trophy
 data from trophyNN.ucp

The title's sce_sys/trophy2/trophyNN.ucp is read on first use with a
bounds-checked .ucp reader and a small JSON reader. tropconf.json gives
each trophy's grade, group, hidden and reward flags, platinum and
unlock condition, and tropmeta_<tag>.json its texts in the console
language, then en-US, then the file's default language. Contexts
remember their user and service label, so the queries find the file.

The trophy, group and game queries report these names, grades, groups
and counts, list every trophy and group, and give progressive trophies
their target. Unlocks are not recorded yet, so every trophy reports as
locked and nothing is written to the host. A missing file is ignored
and a malformed one is logged once; either way the queries keep their
placeholders. A JSON document that nests deeper than 64 levels or holds
more than 1048576 values counts as malformed, which keeps the parsed
values to about 140 MiB.

 - [sceNpTrophy2GetRewardIcon](../../../core/libs/prx/libSceNpTrophy2/src/Context.cpp) (libSceNpTrophy2) takes `(int context, int handle, int reward_id, void* buffer, size_t* size)`, from the call sites in the bundled `Media/Plugins/PSNCore.prx` of PPSA06888, the same shape as `sceNpTrophy2GetTrophyIcon`. The title calls it twice: first with a null buffer to read the size, then with a buffer of that size allocated with `malloc`. The meaning of the third argument is unverified, and the reward icon data is unknown, so every call throws

+- [Trophy queries](../../../core/libs/prx/libSceNpTrophy2/src/TrophyInfo.cpp) report the title's [trophy data](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp) (`sce_sys/trophy2/trophyNN.ucp`). Without the file, or when it is malformed, they report the old placeholders and `sceNpTrophy2GetTrophyInfoArray` lists only trophy 0. Icons are not read. Hidden trophies report their names and descriptions; whether the console blanks them before the unlock is not known. `progress_percentage` weighs gold 6, silver 2 and bronze 1 and leaves the platinum out, as KytyPS5 does (the ratio of the published PSN trophy points); the console's formula is not known. A trophy or group that is not in the file throws. Unlocks are not recorded, so every trophy reports as locked, with no unlock time and a progress of 0, and the unlocked counts and `progress_percentage` are 0. A context that was not created or was destroyed reports placeholders and returns success; the console's errors for it are unknown.
+- [Trophy data limits](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp): a `trophyNN.ucp` larger than 256 MiB or listing more than 4096 files, and a JSON file in it that nests deeper than 64 levels or holds more than 1048576 values, are not used, and the title runs as without that file. The limits keep the memory the reader takes to the file and about 140 MiB of parsed JSON; the console's limits are not known.
+- [Text language](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp): texts come from `tropmeta_<tag>.json` for the console language, then `en-US`, then the file's `defaultLanguage`. The tags for languages 0 to 29 are KytyPS5's; `uk-UA` for 30 (Ukrainian) is an assumption.

 Games ask for the console's language with `sceSystemServiceParamGetInt` and show their text in it when they have it. It is English (United States) unless `ANYPS5_LANGUAGE` is set to another console language number: 0 Japanese, 1 English (United States), 2 French, 3 Spanish, 4 German, 5 Italian, 6 Dutch, 7 Portuguese (Portugal), 8 Russian, 9 Korean, 10 Chinese (Traditional), 11 Chinese (Simplified), 12 Finnish, 13 Swedish, 14 Danish, 15 Norwegian, 16 Polish, 17 Portuguese (Brazil), 18 English (United Kingdom), 19 Turkish, 20 Spanish (Latin America), 21 Arabic, 22 French (Canada), 23 Czech, 24 Hungarian, 25 Greek, 26 Romanian, 27 Thai, 28 Vietnamese, 29 Indonesian, 30 Ukrainian. For example, `ANYPS5_LANGUAGE=21` selects Arabic. An empty value is the same as an unset one; any other value stops the game at its first language query with an error that names the variable.
 
+### Trophies
+
+The trophy data comes from the game's own `app0/sce_sys/trophy2/trophyNN.ucp`, where `NN` is the service label (`00` for most games). The trophy queries report its names, descriptions and rewards in the console language (`ANYPS5_LANGUAGE`, see above), or in English (United States) or the data's default language when it has no text in that language, and its grades, groups, hidden flags, number of trophies and grade counts. The first trophy query prints what was read, such as `[trophy] /app0/sce_sys/trophy2/trophy00.ucp: 52 trophies, 1 group, texts in en-US`.
+
+Trophies are not unlocked yet: every trophy reports as locked, and nothing is written for them. A missing or malformed `trophyNN.ucp` makes the queries report placeholders, and a malformed one prints the reason once; `APS5_TRACE_UDS=1` prints a `[uds]` line for a missing one. Icons are not read: `sceNpTrophy2GetGameIcon`, `sceNpTrophy2GetGroupIcon`, `sceNpTrophy2GetTrophyIcon` and `sceNpTrophy2GetRewardIcon` stop the game with an error. No notification is shown, and callbacks registered with `sceNpTrophy2RegisterUnlockCallback` are not called.
+
 ### PlayGo dumps without metadata
 
 When a dump has neither `sce_sys/playgo-chunk.dat` nor `sce_sys/playgo-scenario.json`, AnyPS5 cannot tell which nonzero PlayGo chunk IDs exist. Requests for those IDs stop with an error by default. Set `APS5_PLAYGO_UNLISTED_CHUNKS` to choose an answer for that dump:

Subject: [PATCH 0906/1000] feat(libSceNpTrophy2): record trophy unlocks per
 title and user

Unlocks are kept in _trophy/<user id>_<service label>.txt in the title's
run directory, one "<trophy id> <RTC tick>" line per trophy, and each new
unlock logs "[trophy] <title id> unlocked trophy <id> for user <id>".
GetTrophyInfo, GetTrophyInfoArray, GetGroupInfo, GetGroupInfoArray and
GetGameInfo report the recorded unlocks, their times, the unlocked
counts by grade and the progress percentage. An unlock also unlocks the
platinum the trophy names once every trophy naming that platinum is
unlocked. Unlock listeners let a later notification subscribe. Removing a
listener waits for its running callback, and a listener removed during a
dispatch is not called by it.

The limits keep the memory the reader takes to the file and about 140 MiB of parsed JSON; the console's limits are not known.
 - [Text language](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp): texts come from `tropmeta_<tag>.json` for the console language, then `en-US`, then the file's `defaultLanguage`. The tags for languages 0 to 29 are KytyPS5's; `uk-UA` for 30 (Ukrainian) is an assumption.
+- [Platinum](../../../core/libs/prx/libSceNpTrophy2/src/TitleTrophies.cpp): an unlock through any path unlocks the platinum that the trophy names in `platinumTrophyId` once every trophy naming that platinum is unlocked, as KytyPS5 does; trophies without `platinumTrophyId` are not required. Without trophy data any id of 0 or more is stored, and the platinum is not unlocked when the trophies it needs are.

Subject: [PATCH 0907/1000] feat(libSceNpUniversalDataSystem): keep event
 properties and record posted trophy unlocks

Events and property objects keep their typed properties instead of
dropping them. PostEvent records an _UnlockTrophy event with an int32
_trophy_id for the user and service label of its context, logs why a
trophy event is ignored, and prints every posted event with
APS5_TRACE_UDS.

 - [Trophy queries](../../../core/libs/prx/libSceNpTrophy2/src/TrophyInfo.cpp) report the title's [trophy data](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp) (`sce_sys/trophy2/trophyNN.ucp`) and the unlocks in the [trophy store](../../../core/libs/prx/libSceNpTrophy2/src/TrophyStore.cpp). Without the file, or when it is malformed, they report the old placeholders and `sceNpTrophy2GetTrophyInfoArray` lists only trophy 0. Icons are not read. Hidden trophies report their names and descriptions; whether the console blanks them before the unlock is not known. `progress_percentage` weighs gold 6, silver 2 and bronze 1 and leaves the platinum out, as KytyPS5 does (the ratio of the published PSN trophy points); the console's formula is not known. A trophy or group that is not in the file throws. A context that was not created or was destroyed reports placeholders and no unlocks and returns success; the console's errors for it are unknown.
 - [Trophy data limits](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp): a `trophyNN.ucp` larger than 256 MiB or listing more than 4096 files, and a JSON file in it that nests deeper than 64 levels or holds more than 1048576 values, are not used, and the title runs as without that file. The limits keep the memory the reader takes to the file and about 140 MiB of parsed JSON; the console's limits are not known.
 - [Text language](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp): texts come from `tropmeta_<tag>.json` for the console language, then `en-US`, then the file's `defaultLanguage`. The tags for languages 0 to 29 are KytyPS5's; `uk-UA` for 30 (Ukrainian) is an assumption.
-- [Platinum](../../../core/libs/prx/libSceNpTrophy2/src/TitleTrophies.cpp): an unlock through any path unlocks the platinum that the trophy names in `platinumTrophyId` once every trophy naming that platinum is unlocked, as KytyPS5 does; trophies without `platinumTrophyId` are not required. Without trophy data any id of 0 or more is stored, and the platinum is not unlocked when the trophies it needs are.

A platinum or a progressive trophy can still be unlocked directly with `_UnlockTrophy`, which KytyPS5 refuses; the console's behaviour is not known.

+- [Events](../../../core/libs/prx/libSceNpUniversalDataSystem/src/Event.cpp): `sceNpUniversalDataSystemCreateEvent` copies `prop` and returns the event's own property object through `prop_ptr`, as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/9e41d8320a2774b303fbad344c2347e8d0292e83/src/libs/libTrophy.cpp) does; `sceNpUniversalDataSystemEventPropertyObjectSetObject`, `SetArray` and the array setters for objects and arrays store a copy of `value` and return the stored copy through `value_ptr`. Destroying a property object or array that its Create function did not return (an event's property object or a stored copy) does nothing, as its owner frees it. These ownership rules are not verified on a console, nor are the output of `sceNpUniversalDataSystemEventToString` (still `{}`) and `sceNpUniversalDataSystemEventEstimateSize` (still 3).
+
+### Functional
+
+- [Trophy events](../../../core/libs/prx/libSceNpUniversalDataSystem/src/Event.cpp): `sceNpUniversalDataSystemPostEvent` stores an `_UnlockTrophy` event with an int32 `_trophy_id` of 0 or more as an unlock for the user and service label of its context, as KytyPS5 does. Unlocks that a title drives through statistics (`statsExtractionRuleArray` in `sce_sys/uds/udsNN.ucp` and `unlockCondition` in `sce_sys/trophy2/trophyNN.ucp`) are not evaluated, and `_UpdateTrophyProgress`, named only by a third-party unlocker, is logged once per trophy and not interpreted. A context need not be registered, and every post of an event that `sceNpUniversalDataSystemCreateEvent` returned and that is not yet destroyed returns success (a null or any other event pointer stops the game): KytyPS5's errors for an unknown or unregistered context and for a malformed unlock are not verified. The storage statistics stay zero.

 ### Trophies
 
-The trophy data comes from the game's own `app0/sce_sys/trophy2/trophyNN.ucp`, where `NN` is the service label (`00` for most games). The trophy queries report its names, descriptions and rewards in the console language (`ANYPS5_LANGUAGE`, see above), or in English (United States) or the data's default language when it has no text in that language, and its grades, groups, hidden flags, number of trophies and grade counts. The first trophy query prints what was read, such as `[trophy] /app0/sce_sys/trophy2/trophy00.ucp: 52 trophies, 1 group, texts in en-US`.
+A game unlocks a trophy by posting a `_UnlockTrophy` event with an int32 `_trophy_id` property to `libSceNpUniversalDataSystem`. The unlock is stored in `_trophy/<user id>_<service label>.txt` in the directory the game runs in (the one that holds `app0/`), one `<trophy id> <unlock time>` line per trophy; the time is an RTC tick, microseconds since 0001-01-01 UTC. Delete the file before starting the game to lock its trophies again. Each new unlock prints one line, such as `[trophy] PPSA01556 unlocked trophy 12 for user 268435456`; unlocking a trophy again prints nothing. `sceNpTrophy2GetTrophyInfo`, `sceNpTrophy2GetTrophyInfoArray` and `sceNpTrophy2GetGameInfo` report the stored unlocks and their times to the game. Every posted `_trophy_id` of 0 or more is stored, even one the trophy data has no trophy for or makes the platinum or a progressive trophy.
 
-Trophies are not unlocked yet: every trophy reports as locked, and nothing is written for them. A missing or malformed `trophyNN.ucp` makes the queries report placeholders, and a malformed one prints the reason once; `APS5_TRACE_UDS=1` prints a `[uds]` line for a missing one. Icons are not read: `sceNpTrophy2GetGameIcon`, `sceNpTrophy2GetGroupIcon`, `sceNpTrophy2GetTrophyIcon` and `sceNpTrophy2GetRewardIcon` stop the game with an error. No notification is shown, and callbacks registered with `sceNpTrophy2RegisterUnlockCallback` are not called.
+The trophy data comes from the game's own `app0/sce_sys/trophy2/trophyNN.ucp`, where `NN` is the service label (`00` for most games). The trophy queries report its names, descriptions and rewards in the console language (`ANYPS5_LANGUAGE`, see above), or in English (United States) or the data's default language when it has no text in that language, and its grades, groups, hidden flags, number of trophies and grade counts. A platinum trophy unlocks as soon as every trophy that names it in `platinumTrophyId` is unlocked. The first trophy query or event prints what was read, such as `[trophy] /app0/sce_sys/trophy2/trophy00.ucp: 52 trophies, 1 group, texts in en-US`.
+
+`APS5_TRACE_UDS=1` prints every posted event, such as `[uds] context 1 posted _UnlockTrophy {"_trophy_id":12}`, and a `[uds]` line for a missing `trophyNN.ucp`. An event that is not used prints the reason in a `[trophy] ignored` line: an `_UnlockTrophy` event without an int32 `_trophy_id` of 0 or more, or posted to a context that does not exist, and the first `_UpdateTrophyProgress` event of each trophy, because trophy progress is not recorded.
+
+A missing or malformed `trophyNN.ucp` makes the queries report placeholders, and a malformed one prints the reason once. Icons are not read: `sceNpTrophy2GetGameIcon`, `sceNpTrophy2GetGroupIcon`, `sceNpTrophy2GetTrophyIcon` and `sceNpTrophy2GetRewardIcon` stop the game with an error. So does an unlock file in `_trophy/` that is damaged (a line that is not a new `<id> <value>` pair, such as a line an edit left blank or ended with a carriage return) or cannot be read or written. No notification is shown, and callbacks registered with `sceNpTrophy2RegisterUnlockCallback` are not called.

Subject: [PATCH 0909/1000] feat(libSceNpUniversalDataSystem): unlock trophies
 through the title's statistics

Events other than the trophy events go through the title's
sce_sys/uds/udsNN.ucp: stats_definition.json gives the statistics that
keep their latest uint32 or uint64 value, and stats_extraction.json the
event property ($.name, dotted for nested objects) that sets each one.
Statistics are kept per user and service label in
_trophy/<user id>_<service label>.stats.txt next to the unlocks.

After each event that sets a statistic, every trophy's unlockCondition
(ge, gt, le or lt against its targetValue) is checked on the values that
event set and the stored values of the other statistics, so a later
event setting the same statistic cannot hide what this one reached.
Reached trophies unlock through the same path as _UnlockTrophy.
Progressive trophies report their statistic as progress, and
APS5_TRACE_UDS prints each statistic an event sets. A missing udsNN.ucp
is ignored and a malformed one is logged once.

Without the file, or when it is malformed, they report the old placeholders and `sceNpTrophy2GetTrophyInfoArray` lists only trophy 0. Icons are not read. Hidden trophies report their names and descriptions; whether the console blanks them before the unlock is not known. `progress_percentage` weighs gold 6, silver 2 and bronze 1 and leaves the platinum out, as KytyPS5 does (the ratio of the published PSN trophy points); the console's formula is not known. A trophy or group that is not in the file throws. A context that was not created or was destroyed reports placeholders and no unlocks and returns success; the console's errors for it are unknown.

 - [Platinum](../../../core/libs/prx/libSceNpTrophy2/src/TitleTrophies.cpp): an unlock through any path unlocks the platinum that the trophy names in `platinumTrophyId` once every trophy naming that platinum is unlocked, as KytyPS5 does; trophies without `platinumTrophyId` are not required. A platinum or a progressive trophy can still be unlocked directly with `_UnlockTrophy`, which KytyPS5 refuses; the console's behaviour is not known. Without trophy data any id of 0 or more is stored, and the platinum is not unlocked when the trophies it needs are.

Only statistics with `"aggregation":"latest"` and `dataType` `uint32` or `uint64` are kept, as in KytyPS5; no public source documents the other aggregations or types, so their definitions and rules are skipped. Only rules whose condition is an `eventName` alone and whose input is a `$.name` path (dotted for nested objects) are applied. A value is used when it is an integer of any width that is not negative and fits the statistic's type and `minValue`/`maxValue`; KytyPS5 requires the statistic's exact width, and whether the console converts, clamps or rejects other values is not known. Statistics are stored per user and service label, and every trophy's `unlockCondition` is compared after each event that sets one.

 ### Trophies
 
-A game unlocks a trophy by posting a `_UnlockTrophy` event with an int32 `_trophy_id` property to `libSceNpUniversalDataSystem`. The unlock is stored in `_trophy/<user id>_<service label>.txt` in the directory the game runs in (the one that holds `app0/`), one `<trophy id> <unlock time>` line per trophy; the time is an RTC tick, microseconds since 0001-01-01 UTC. Delete the file before starting the game to lock its trophies again. Each new unlock prints one line, such as `[trophy] PPSA01556 unlocked trophy 12 for user 268435456`; unlocking a trophy again prints nothing. `sceNpTrophy2GetTrophyInfo`, `sceNpTrophy2GetTrophyInfoArray` and `sceNpTrophy2GetGameInfo` report the stored unlocks and their times to the game. Every posted `_trophy_id` of 0 or more is stored, even one the trophy data has no trophy for or makes the platinum or a progressive trophy.
+A game unlocks a trophy by posting a `_UnlockTrophy` event with an int32 `_trophy_id` property to `libSceNpUniversalDataSystem`, or through the statistics rules described below. The unlock is stored in `_trophy/<user id>_<service label>.txt` in the directory the game runs in (the one that holds `app0/`), one `<trophy id> <unlock time>` line per trophy; the time is an RTC tick, microseconds since 0001-01-01 UTC. Delete the file before starting the game to lock its trophies again. Each new unlock prints one line, such as `[trophy] PPSA01556 unlocked trophy 12 for user 268435456`; unlocking a trophy again prints nothing. `sceNpTrophy2GetTrophyInfo`, `sceNpTrophy2GetTrophyInfoArray` and `sceNpTrophy2GetGameInfo` report the stored unlocks and their times to the game. Every posted `_trophy_id` of 0 or more is stored, even one the trophy data has no trophy for or makes the platinum or a progressive trophy.
 
 The trophy data comes from the game's own `app0/sce_sys/trophy2/trophyNN.ucp`, where `NN` is the service label (`00` for most games). The trophy queries report its names, descriptions and rewards in the console language (`ANYPS5_LANGUAGE`, see above), or in English (United States) or the data's default language when it has no text in that language, and its grades, groups, hidden flags, number of trophies and grade counts. A platinum trophy unlocks as soon as every trophy that names it in `platinumTrophyId` is unlocked. The first trophy query or event prints what was read, such as `[trophy] /app0/sce_sys/trophy2/trophy00.ucp: 52 trophies, 1 group, texts in en-US`.
 
-`APS5_TRACE_UDS=1` prints every posted event, such as `[uds] context 1 posted _UnlockTrophy {"_trophy_id":12}`, and a `[uds]` line for a missing `trophyNN.ucp`. An event that is not used prints the reason in a `[trophy] ignored` line: an `_UnlockTrophy` event without an int32 `_trophy_id` of 0 or more, or posted to a context that does not exist, and the first `_UpdateTrophyProgress` event of each trophy, because trophy progress is not recorded.
+Many games unlock trophies through statistics instead: `app0/sce_sys/uds/udsNN.ucp` names, for each event, the property whose value becomes a statistic, and a trophy's `unlockCondition` compares a statistic with a target. The latest value of each statistic is stored in `_trophy/<user id>_<service label>.stats.txt`, one `<stat id> <value>` line per statistic, and is kept across runs; delete it together with the unlock file to start over. A progressive trophy reports its statistic as progress. Only statistics that keep the latest value (`"aggregation":"latest"`) as `uint32` or `uint64`, and rules that copy one property of an event chosen by its name (`$.name` or `$.object.name`), are applied; the others are listed in `[trophy]` lines when the file is read.
 
-A missing or malformed `trophyNN.ucp` makes the queries report placeholders, and a malformed one prints the reason once. Icons are not read: `sceNpTrophy2GetGameIcon`, `sceNpTrophy2GetGroupIcon`, `sceNpTrophy2GetTrophyIcon` and `sceNpTrophy2GetRewardIcon` stop the game with an error. So does an unlock file in `_trophy/` that is damaged (a line that is not a new `<id> <value>` pair, such as a line an edit left blank or ended with a carriage return) or cannot be read or written. No notification is shown, and callbacks registered with `sceNpTrophy2RegisterUnlockCallback` are not called.
+`APS5_TRACE_UDS=1` prints every posted event, such as `[uds] context 1 posted _UnlockTrophy {"_trophy_id":12}`, every statistic an event sets, such as `[uds] stat 10 of user 268435456 is 10 (COLLECT $.counter)`, and a `[uds]` line for a missing `trophyNN.ucp` or `udsNN.ucp`. An event that is not used prints the reason in a `[trophy] ignored` line: an `_UnlockTrophy` event without an int32 `_trophy_id` of 0 or more, or posted to a context that does not exist; the first `_UpdateTrophyProgress` event of each trophy, because that event is not interpreted; and, once per rule, an event whose property is missing, negative, not an integer or outside the statistic's range.
+
+A missing or malformed `trophyNN.ucp` or `udsNN.ucp` turns off only what it provides, and a malformed one prints the reason once: without trophy data the queries report placeholders and statistics unlock nothing, and without statistics rules events change no statistic. Icons are not read: `sceNpTrophy2GetGameIcon`, `sceNpTrophy2GetGroupIcon`, `sceNpTrophy2GetTrophyIcon` and `sceNpTrophy2GetRewardIcon` stop the game with an error. So does an unlock or statistics file in `_trophy/` that is damaged (a line that is not a new `<id> <value>` pair, such as a line an edit left blank or ended with a carriage return) or cannot be read or written. No notification is shown, and callbacks registered with `sceNpTrophy2RegisterUnlockCallback` are not called.

Subject: [PATCH 0911/1000] test(libSceNpUniversalDataSystem): check that a
 stat with a sum aggregation unlocks nothing

A title whose uds file defines a stat with an aggregation other than
latest gets one log line naming the stat. Posting an event for it
through the exports stores no stat and unlocks no trophy.

Subject: [PATCH 0912/1000] fix(libSceNpTrophy2): refuse a posted unlock of an
 unknown, platinum or progressive trophy

With the title's trophy data loaded, an _UnlockTrophy posted through UDS
no longer records an id the data does not have, the platinum, or a
progressive trophy. Each refusal logs the trophy and the reason, returns
false and calls no listener.

The statistics path and the platinum award now use an internal record
that keeps part 1's behaviour, so a progressive trophy still unlocks
through its statistic and the platinum with the last trophy that names
it. Without trophy data every id of 0 or more is recorded as before.

Subject: [PATCH 0913/1000] docs: say which posted trophy unlocks are refused
 and what stops a title

USAGE.md describes the refused posted unlocks and their log line, and
says that the icon queries and a damaged or unwritable unlock or
statistics file stop the game with an error. The debt entries of
libSceNpTrophy2 and libSceNpUniversalDataSystem no longer say that any
posted id is stored. Both USAGE.md and the libSceNpTrophy2 entry say
that without trophy data the platinum is not unlocked when the other
trophies are.

 - [Trophy queries](../../../core/libs/prx/libSceNpTrophy2/src/TrophyInfo.cpp) report the title's [trophy data](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp) (`sce_sys/trophy2/trophyNN.ucp`) and the unlocks in the [trophy store](../../../core/libs/prx/libSceNpTrophy2/src/TrophyStore.cpp). Without the file, or when it is malformed, they report the old placeholders and `sceNpTrophy2GetTrophyInfoArray` lists only trophy 0. Icons are not read. Hidden trophies report their names and descriptions; whether the console blanks them before the unlock is not known. `progress_percentage` weighs gold 6, silver 2 and bronze 1 and leaves the platinum out, as KytyPS5 does (the ratio of the published PSN trophy points); the console's formula is not known. A trophy or group that is not in the file throws. A context that was not created or was destroyed reports placeholders and no unlocks and returns success; the console's errors for it are unknown.
 - [Trophy data limits](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp): a `trophyNN.ucp` or `udsNN.ucp` larger than 256 MiB or listing more than 4096 files, and a JSON file in it that nests deeper than 64 levels or holds more than 1048576 values, are not used, and the title runs as without that file. The limits keep the memory the reader takes to the file and about 140 MiB of parsed JSON; the console's limits are not known.
 - [Text language](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp): texts come from `tropmeta_<tag>.json` for the console language, then `en-US`, then the file's `defaultLanguage`. The tags for languages 0 to 29 are KytyPS5's; `uk-UA` for 30 (Ukrainian) is an assumption.
-- [Platinum](../../../core/libs/prx/libSceNpTrophy2/src/TitleTrophies.cpp): an unlock through any path unlocks the platinum that the trophy names in `platinumTrophyId` once every trophy naming that platinum is unlocked, as KytyPS5 does; trophies without `platinumTrophyId` are not required. A platinum or a progressive trophy can still be unlocked directly with `_UnlockTrophy`, which KytyPS5 refuses; the console's behaviour is not known. Without trophy data any id of 0 or more is stored, and the platinum is not unlocked when the trophies it needs are.
+- [Platinum](../../../core/libs/prx/libSceNpTrophy2/src/TitleTrophies.cpp): an unlock through any path unlocks the platinum that the trophy names in `platinumTrophyId` once every trophy naming that platinum is unlocked, as KytyPS5 does; trophies without `platinumTrophyId` are not required. With the title's trophy data loaded, a posted `_UnlockTrophy` of a trophy that is not in the data, of a platinum or of a progressive trophy is not stored and prints a `[trophy] ignored` line, as KytyPS5 refuses them, so a progressive trophy unlocks only through its statistic; without trophy data any id of 0 or more is stored, including ids the data would make the platinum, a progressive trophy or no trophy, and the platinum is not unlocked when the trophies it needs are. The console's behaviour is not known.

 ### Functional
 
-- [Trophy events](../../../core/libs/prx/libSceNpUniversalDataSystem/src/Event.cpp): `sceNpUniversalDataSystemPostEvent` stores an `_UnlockTrophy` event with an int32 `_trophy_id` of 0 or more as an unlock for the user and service label of its context, as KytyPS5 does. `_UpdateTrophyProgress`, named only by a third-party unlocker, is logged once per trophy and not interpreted. A context need not be registered, and every post of an event that `sceNpUniversalDataSystemCreateEvent` returned and that is not yet destroyed returns success (a null or any other event pointer stops the game): KytyPS5's errors for an unknown or unregistered context and for a malformed unlock are not verified. The storage statistics stay zero.

 - [Statistics](../../../core/libs/prx/libSceNpUniversalDataSystem/src/Event.cpp): every other event goes through the title's rules in `sce_sys/uds/udsNN.ucp`, which [libSceNpTrophy2](../../../core/libs/prx/libSceNpTrophy2/src/TitleTrophies.cpp) reads. Only statistics with `"aggregation":"latest"` and `dataType` `uint32` or `uint64` are kept, as in KytyPS5; no public source documents the other aggregations or types, so their definitions and rules are skipped. Only rules whose condition is an `eventName` alone and whose input is a `$.name` path (dotted for nested objects) are applied. A value is used when it is an integer of any width that is not negative and fits the statistic's type and `minValue`/`maxValue`; KytyPS5 requires the statistic's exact width, and whether the console converts, clamps or rejects other values is not known. Statistics are stored per user and service label, and every trophy's `unlockCondition` is compared after each event that sets one.

 ### Trophies
 
-A game unlocks a trophy by posting a `_UnlockTrophy` event with an int32 `_trophy_id` property to `libSceNpUniversalDataSystem`, or through the statistics rules described below. The unlock is stored in `_trophy/<user id>_<service label>.txt` in the directory the game runs in (the one that holds `app0/`), one `<trophy id> <unlock time>` line per trophy; the time is an RTC tick, microseconds since 0001-01-01 UTC. Delete the file before starting the game to lock its trophies again. Each new unlock prints one line, such as `[trophy] PPSA01556 unlocked trophy 12 for user 268435456`; unlocking a trophy again prints nothing. `sceNpTrophy2GetTrophyInfo`, `sceNpTrophy2GetTrophyInfoArray` and `sceNpTrophy2GetGameInfo` report the stored unlocks and their times to the game. Every posted `_trophy_id` of 0 or more is stored, even one the trophy data has no trophy for or makes the platinum or a progressive trophy.

When the game's trophy data is loaded (see below), a posted unlock of a trophy that the data does not have, of the platinum, or of a progressive trophy is not stored and prints the reason, such as `[trophy] ignored the posted unlock of trophy 0 for user 268435456: it is the platinum, which unlocks with the last trophy that names it`; the platinum unlocks with the last trophy that names it, and a progressive trophy through its statistic. Without trophy data every posted id of 0 or more is stored, and the platinum is not unlocked when the other trophies are.
 
 The trophy data comes from the game's own `app0/sce_sys/trophy2/trophyNN.ucp`, where `NN` is the service label (`00` for most games). The trophy queries report its names, descriptions and rewards in the console language (`ANYPS5_LANGUAGE`, see above), or in English (United States) or the data's default language when it has no text in that language, and its grades, groups, hidden flags, number of trophies and grade counts. A platinum trophy unlocks as soon as every trophy that names it in `platinumTrophyId` is unlocked. The first trophy query or event prints what was read, such as `[trophy] /app0/sce_sys/trophy2/trophy00.ucp: 52 trophies, 1 group, texts in en-US`.

 - [Trophy data limits](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp): a `trophyNN.ucp` or `udsNN.ucp` larger than 256 MiB or listing more than 4096 files, and a JSON file in it that nests deeper than 64 levels or holds more than 1048576 values, are not used, and the title runs as without that file. The limits keep the memory the reader takes to the file and about 140 MiB of parsed JSON; the console's limits are not known.
 - [Text language](../../../core/libs/prx/libSceNpTrophy2/src/TrophyPackage.cpp): texts come from `tropmeta_<tag>.json` for the console language, then `en-US`, then the file's `defaultLanguage`. The tags for languages 0 to 29 are KytyPS5's; `uk-UA` for 30 (Ukrainian) is an assumption.
 - [Platinum](../../../core/libs/prx/libSceNpTrophy2/src/TitleTrophies.cpp): an unlock through any path unlocks the platinum that the trophy names in `platinumTrophyId` once every trophy naming that platinum is unlocked, as KytyPS5 does; trophies without `platinumTrophyId` are not required. With the title's trophy data loaded, a posted `_UnlockTrophy` of a trophy that is not in the data, of a platinum or of a progressive trophy is not stored and prints a `[trophy] ignored` line, as KytyPS5 refuses them, so a progressive trophy unlocks only through its statistic; without trophy data any id of 0 or more is stored, including ids the data would make the platinum, a progressive trophy or no trophy, and the platinum is not unlocked when the trophies it needs are. The console's behaviour is not known.
+- [Damaged records](../../../core/libs/prx/libSceNpTrophy2/src/TrophyStore.cpp): a line in `_trophy/<user id>_<service label>.txt` or `.stats.txt` that is not a new `<id> <value>` pair (a blank line, a carriage return, a repeated or negative id, a value that is not a number) makes `readRecord` throw a `std::runtime_error` that names the file and the line. Every call that reads that record then throws it instead of returning, which stops the title as any throwing export does, so the title gets no return value; main returned 0 from these calls. The failed read is not kept, so each later call reads the file again and throws again until the file is fixed or deleted. The unlock record is read by `sceNpTrophy2GetTrophyInfo`, `sceNpTrophy2GetTrophyInfoArray` and `sceNpTrophy2GetGameInfo` for a created context, by `sceNpTrophy2GetGroupInfo` and `sceNpTrophy2GetGroupInfoArray` when the title's trophy data is loaded, by a `sceNpUniversalDataSystemPostEvent` of an `_UnlockTrophy` that the trophy data does not refuse, and by a statistic change when the trophy data is loaded; the stat record by a `sceNpUniversalDataSystemPostEvent` of an event that a statistics rule copies and by the trophy queries of a progressive trophy with a statistic. What the console does with a damaged record is not known.

 ### Silent stubs
 
-- [libSceHmd2](../../../core/libs/prx/libSceHmd2/Export.cpp) has no PS VR2 runtime: `sceHmd2Initialize` fails, and every other export it has (and every [libSceVrTracker2](../../../core/libs/prx/libSceVrTracker2/Export.cpp) export) throws. PPSA01317 skips its whole VR set-up when initialization fails
+- [libSceHmd2](../../../core/libs/prx/libSceHmd2/Export.cpp) reports a console without a PS VR2 headset, as firmware 13.20's libSceHmd2 does with the `/dev/hmd2_cmd` state measured on a retail PS5 with none connected (connected flag 0, status 2, user -1): initialization succeeds, `sceHmd2Open` returns a handle, device information reports `NotDetected` with the firmware's fixed panel, latency and image distance values, both field-of-view calls return the firmware's default tangents and `sceHmd2SetVibration` succeeds without vibrating. The reprojection and gaze exports and every [libSceVrTracker2](../../../core/libs/prx/libSceVrTracker2/Export.cpp) export throw. PPSA01317, PPSA07411, PPSA09030, PPSA15878 and PPSA29866, which skipped their VR set-up while initialization failed, have not been run with initialization succeeding
 
 ### Unknown function info
 
 - PPSA29866 imports declared without parameters, signatures unknown, added without an implementation because the title fails to load without them: [sceHmd2ReprojectionQuerySeeThroughBufferSizeAlign](../../../core/libs/prx/libSceHmd2/Export.cpp) (libSceHmd2), [sceVideoOutSetFlipMaster and sceVideoOutClearFlipMaster](../../../core/libs/prx/libSceVideoOut/Unimplemented.cpp) (libSceVideoOut)
 - PPSA09030 imports from its `Media/Plugins/psvr2.prx` declared without parameters, signatures unknown, added without an implementation because the title fails to load the plugin without them: [sceHmd2ReprojectionGetStatus](../../../core/libs/prx/libSceHmd2/Export.cpp) (libSceHmd2), [sceVrTracker2GetCoordinateSystem and sceVrTracker2GetPlayAreaBoundaryGeometry](../../../core/libs/prx/libSceVrTracker2/Export.cpp) (libSceVrTracker2)
-- [sceHmd2Initialize](../../../core/libs/prx/libSceHmd2/Export.cpp) (libSceHmd2) - the error the console returns when the PS VR2 runtime is unavailable is unknown; it returns libSceHmd's `UNSUPPORTED_FEATURE` (0x81110016). PPSA01317 passes a pointer to 16 zeroed bytes and only tests the result for non-zero
-- PPSA01317 imports declared without parameters, signatures unknown: the remaining [libSceHmd2](../../../core/libs/prx/libSceHmd2/Export.cpp) and [libSceVrTracker2](../../../core/libs/prx/libSceVrTracker2/Export.cpp) exports. Names from the aerolib NID list
+- [sceHmd2Initialize](../../../core/libs/prx/libSceHmd2/Export.cpp) (libSceHmd2) - the firmware also fails with 0x8a72001f when `sceKernelGetAppInfo` fails and with 0x8a72000a for some applications, depending on app info fields at 0x2c, 0x4b and 0x4d whose meaning is unknown, and then calls `sceMbusInit`; none of this is modelled
+- [sceHmd2Open](../../../core/libs/prx/libSceHmd2/Export.cpp) (libSceHmd2) - the handle is the value the console's driver returned to the first open; titles built with an SDK before 7.00 may open for any user, and the firmware's `sceMbusAddHandleByUserId` result for a user other than the initial one is unknown, so that case throws. 0x8a720006 for a second open is named `AlreadyOpened` from its use
+- [sceHmd2SetVibration](../../../core/libs/prx/libSceHmd2/Export.cpp) (libSceHmd2) - the second parameter is checked against 25 only while a headset is connected; its name and unit are unknown. The field of view member names are assumed: of the firmware's default tangents the first is the widest and the last two are equal
+- PPSA01317 imports declared without parameters, signatures unknown: the [libSceHmd2](../../../core/libs/prx/libSceHmd2/Export.cpp) exports that throw and the remaining [libSceVrTracker2](../../../core/libs/prx/libSceVrTracker2/Export.cpp) exports. Names from the aerolib NID list
 - PPSA15878 imports declared without parameters, signatures unknown: the [libSceHmd2](../../../core/libs/prx/libSceHmd2/Export.cpp) reprojection and gaze exports, `sceVrTracker2Finalize`, `sceVrTracker2GetPlayAreaOrientedBoundingBox` and `sceVrTracker2LocateCoordinateSystem` in [libSceVrTracker2](../../../core/libs/prx/libSceVrTracker2/Export.cpp), and the `scePadVrController` trigger effect exports in [libScePad](../../../core/libs/prx/libScePad/Export.cpp).

Subject: [PATCH 0917/1000] perf(agc): let the resource cache bound come back
 down

Halve the grown bound (not below 1024 entries) once a window of the
bound's uses times a shrink window was served by at most a quarter of
it, and reset the bound on Clear(). The shrink window starts at 8 and
doubles (up to 1024) each time growth undoes the last shrink, so a set
of keys that comes back over a longer span stops the bound from
oscillating. The entries over the bound leave at the next insert, with
the other evictions.

Only CPU sequences exist: `initialize` and `calculateRequiredMemorySize` with compute sequences, and both compute dispatches, are not implemented, and `createCompute` and `destroyCompute` return the errors the original returns when no compute sequence was configured. The manager's state lives on the host heap, with only the block header written to the title's memory; the original keeps everything in that block, and a block smaller than 0x2d8 bytes throws here. The worker sleep policy, the spin count and the persistent thread count are validated and stored but change nothing, a factory priority above 1 throws, `shutdown` throws while a thread is blocked in a sequence wait, and using a sequence after its `destroy` throws. `initialize` returns 0 where the original returns the result of its last import (`BG26hBGiNlw`, not resolved to a name), the `sceRazorCpuJobManager*` profiler calls are not made, and a worker thread that cannot be created or configured throws where the original does not check. The order of the sequence and factory virtual functions is read from the modules' vtables only, since no title that calls them has been run

Compute sequences submit through `sceAgcDriverSubmitAcb` on the queue their mask bit selects and are checked the same way by `agc_driver_job_manager_compute_tests`: results, ordering against CPU dispatches and sync points, limits and sizes match the two modules. The command stream is simpler than the original's: every compute dispatch is submitted with its own label write and interrupt, where the original batches the label write and rewinds commands it encoded ahead, and the command buffers and labels live on the host heap. The per-queue command size in `calculateRequiredMemorySize` is a constant (104, 148 and 32 bytes per dispatch, sync point and wait), which is what the original measures by running the builders of this project's libSceAgc. A compute dispatch on a CPU sequence throws (the original does not check), and a failing `sceAgcDriverAddEqEvent` throws. The manager's state lives on the host heap, with only the block header written to the title's memory; the original keeps everything in that block, and a block smaller than 0x2d8 bytes throws here.

Threshold, per-axis test and default follow [duaLib](https://github.com/WujekFoliarz/duaLib/blob/03bad1bea2a36561b520846776f2a07ced6773e0/src/source/duaLib.cpp#L44), which reimplements the PC `libScePad.dll`; the console's threshold is not measured, and the deadband is kept per library rather than per handle since one pad handle exists
 - [scePadOpen and scePadOpenExt](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - special ports (type 2) return `DEVICE_NOT_CONNECTED` (0x80920007) because the host has no special controller, and `scePadGetHandle` has no handle for them; whether the console opens a handle and reports the device as disconnected later is unknown. scePadOpenExt handles only special ports. PPSA01317 passes a 16-byte param that names the device by vendor and product id (`b7 0e 04 0e ...` for 0x0eb7:0x0e04) and skips the user on any negative result. Other port types throw
 - [scePadVrControllerReadState](../../../core/libs/prx/libScePad/Export.cpp) (libScePad, NID `iA-DdobUen8`) - the name hashes to the imported NID; the `(int handle, void* state)` signature follows [PS5VR](https://github.com/theghostonline/PS5VR/blob/0e408909ce7a39891a2e06eee3438d07a09e11e3/app/src/app_vr.c#L326-L369) (PPSA99177), which passes a PS VR2 Sense controller handle from `scePadOpen` type 3 or 4 and a 0x68-byte state it reads as buttons at 0, stick bytes at 4 and a connected byte at 0x40. The title calls it only after `sceHmd2Initialize` succeeds, which it does not here, so every call throws; the state layout is otherwise unknown

 - [scePadSetVibrationMode](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - modes 1 to 3 and 5 are accepted and stored. On a PS5 (firmware 13.60) the call returns `0x80920005` before `scePadInit`, then rejects a mode of 0 or below with `INVALID_ARG` before it checks the handle, and returns `INVALID_HANDLE` for a bad handle with any higher mode; whether an open handle accepts modes above 3 was not measured, since the payload could not open a pad; 5 is accepted because PPSA25286 passes it on its open handle at start-up; the meanings of modes 3 and 5 are unknown (PPSA21480 calls it with 3 right after `scePadOpen` and aborts on failure; [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/Pad/Pad.cs) names only 1 and 2).

 - [scePadIsRemoteController](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - the name hashes to NID `fCWdlnmB1Ks`; the signature `(int handle, bool* remote)` comes from PPSA16064, which zeroes a byte, passes its address after `scePadGetControllerInformation` and ignores the result. The error codes follow the other pad calls. Controllers are local devices, so the answer is always false
 - [scePadSetAngularVelocityBiasCorrectionState](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - inferred signature `(int handle, bool enabled)` follows `scePadSetTiltCorrectionState` and `scePadSetAngularVelocityDeadbandState`; an invalid handle returns `PAD_ERROR_INVALID_HANDLE`, disabling is a no-op, and enabling throws because bias correction is not modelled
 - [scePadUnknown_zBsgF0q8DIM](../../../core/libs/prx/libScePad/Export.cpp) (libScePad, NID `zBsgF0q8DIM`) - PPSA03671 imports it and fails to load without it. The aerolib list has no name for the NID, and none of the pad names in SharpProspero, shadPS4 or OpenOrbis, nor the trigger effect, motion sensor, VR controller, HD and haptic names tried, hashes to it. It is declared without parameters and throws. The title's executable has an import stub for it but no call, jump or address reference to that stub, so the argument count and whether the result is used are unknown

Subject: [PATCH 0922/1000] fix(relinker): append the test temp directory
 instead of replacing the environment

set_tests_properties replaced the ASAN_OPTIONS that add_asan_test_options appends to
guest_module_args, guest_deferred_dependencies and guest_module_fini in ASan builds.
Append the TMPDIR, TEMP and TMP settings instead.

Subject: [PATCH 0924/1000] fix(shader): pass clip distances through the
 rect-list stages as the vertex shader writes them

The recompiled vertex shader writes gl_ClipDistance through a variable of
its own beside its position block, but the rect-list control and
evaluation stages read and wrote it as a second member of their
per-vertex block, so the stage interfaces did not match
(VUID-RuntimeSpirv-OpVariable-08746). They now take and forward the clip
distances through ClipDistance variables of their own.

Subject: [PATCH 0926/1000] fix(agc): keep one trace thread pointer and
 recording flag across modules

PerformanceTrace kept the recording flag and each thread's trace buffer
as inline static members, so on Windows every module that includes the
header had its own copies: agc_driver_registration_trace read an empty
pointer, and libSceVideoOut's timers never saw the trace recording. They
are now defined once in the driver.

Subject: [PATCH 0927/1000] test(agc): create fixture command pools with the
 reset flag

Seven test fixtures create their own command pool without
VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT, while the driver's own
pool sets it and Recorder begins a used command buffer again without an
explicit reset. The Khronos validation layer reports
VUID-vkBeginCommandBuffer-commandBuffer-00050 in depth_storage and
partially_resident_snapshot --pending-stores for this. The fixtures now
create the pool the way VulkanDevice does.

Subject: [PATCH 0929/1000] fix(shader): reduce a DPP row scan read at a row's
 last lane over the active lanes

A row scan (DPP row_shr 1, 2, 4 and 8 over keys that hold the identity on
lanes the wave did not enter with) read with v_readlane at lane 15, 31, 47
or 63 shuffles from lanes that already left the surrounding loop, which are
inactive on the host and whose values are undefined there. The read becomes
a subgroup reduction over the active invocations of that row, per wave32
half when a wave64 host subgroup holds two waves. The saved exec mask set to
every lane (`!x || x`) also counts as every lane.

Subject: [PATCH 0930/1000] test(agc): keep the resource cache growth test
 short

The test now sets a base bound of 32 entries and a first shrink window
of 2 (ResourceCache::SetBase, applied at the next Clear()) and turns
dispatch recipes off, so every dispatch goes through the cache: grow,
shrink, regrow, backoff and the Clear() reset take about 1.2k
dispatches instead of about 100k.

Subject: [PATCH 0933/1000] fix(agc): read a 32-bit depth-bits T# over guest
 memory through a float view

A sampled 32_UINT or 32_SINT T# with a depth swizzle that no live depth
surface matches threw, while the 16-bit case already falls back to guest
memory through an R16_UNORM view. The 32-bit case now reads the guest
bytes through an R32_SFLOAT view, which the shader casts back to the
stored dword.

 - [Multisampled color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) lose their guest-read guards and cannot be reused after a successful allocation removal or unmap covers their full guarded range. Retired Vulkan images remain allocated until device teardown to preserve outstanding references. Partial unmaps keep the guard; partial allocation reuse and guest access to live multisampled data remain unsupported.
 - [Stencil reference export replay](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) on devices without `VK_EXT_shader_stencil_export` supports at most sixteen values proved from constant, select and phi exports, with an export proved on every kept path. It records instances, then their triangles, then the reference classes of each triangle. One pipeline filters fragments at shader termination against a dynamic push value before late stencil and depth tests. The [Vulkan stencil-reference replacement rule](https://docs.vulkan.org/refpages/latest/refpages/source/FragStencilRefEXT.html) discards bits above the attachment's stencil width; supported stencil attachments have eight bits. Numeric subgroup observations throw except bounded own-lane mask plumbing and group control with kept-lane and derivative-helper coverage proved. WQM inputs must exclude helper contributions, since [non-quad subgroup operations may treat helpers as inactive](https://docs.vulkan.org/glslext/latest/glslext/khr/GL_KHR_shader_subgroup.html). Readonly guarded SRT reads may report internal host faults; these draws wait and check faults before publishing results, and loops throw. Indirect draws, restart, strips, fans, tessellation, mesh, multisampling, early tests, ordered pixel execution, guest shader memory writes, other fault-producing memory access, clocks, primitive ID inputs, attachment feedback and pipeline face/channel splits throw. An exhausted stage push range throws. Equivalence to console ordering has not been measured on console hardware.
 
+- [32-bit depth-bits reads of guest memory](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver): a sampled 32_UINT or 32_SINT T# with a depth swizzle mode that no live depth surface matches reads the guest bytes through an R32_SFLOAT image, as the recompiler's depth-bits read expects, and the shader casts the fetched value back to the stored dword. On RX 6700 XT (gfx1031, AMD Windows driver 32.0.21045.5002) the read keeps float denormals, the sign bit alone and quiet and signaling NaN payloads bit for bit. A host that canonicalizes NaNs or flushes denormals on a 32-bit float fetch would change those dwords, and other drivers are not measured. A live depth surface whose extent or base level differs from the T# is not used; the read takes the guest bytes, as the 32-bit float and 16-bit views already do.
 - [Reused depth storage](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp): a storage view with another extent or a format that cannot hold the cached depth plane uses guest memory. Depth rendering is not written back to those guest bytes; this admission rule does not prove allocation reuse or preserve a depth writer through an incompatible view. A 2D storage view, or a one-layer 2D array view of layer 0, of level 0 with the plane's extent and format (32-bit float or the 32-bit depth-bits layout for the depth plane, 16-bit unorm for D16, 8-bit uint for the stencil plane) is a storage image that is [filled](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) from the depth image before every use and, when the shader writes it, copied back after the work: a whole-plane copy through a staging buffer each way. A written view is also left pending like any other storage image, so the plane's content, drawn depth included, reaches guest memory on the next flush of that range. A 2D array view of more than one slice of the depth plane, or of a later slice, is a storage image over the slices from 0 to its last (`LayeredDepthStorage`); only the slices from its base slice to its last are copied: a slice that has a depth surface at the plane's address plus a whole depth slice per layer (`DepthSliceBytes`, as for the depth plane copies below) is copied from that surface before every use and back to it after the work, every bound slice each time, through a staging buffer; the other slices hold guest memory like any storage image. These images are kept per address, extent, slice count, base slice, format and tile mode until the device goes away, outside the storage cache's budget. Such a view needs a layer pitch equal to that slice size, and another view of the same memory (the 2D view of its first slice, a view from another base slice, or a sampled copy) is a separate image, copied in before and out after each use, so views that are written before a flush and share a slice do not merge: the later copy-out wins, so their results are not merged. A matching view still throws when it is a cube, a 2D array of more than one layer of the stencil plane or from a later slice, or another level, when the surface is multisampled, when it names the depth plane of a 16-bit depth with stencil surface the device stores in a wider format, and when it was written after another view of the same plane (another format, tile mode, address or dimension) replaced it, as two such views bound in one dispatch are. Stored depth values outside 0..1 are not clamped, and Vulkan leaves that copy undefined without `VK_EXT_depth_range_unrestricted`. `agc_driver_depth_storage_dispatch` pins these paths; none is measured on the console.
 - [Collapsed color array views](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) preserve the selected slice in the XOR address equation when the view is represented as a shifted 2D surface. Native Vulkan coverage checks R_X draws, array reads, publication and re-upload for slices 1-3; Lost Soul Aside PPSA26358 validates the RGBA16F cube mip chain on Windows/NVIDIA. Other devices and console comparisons remain unverified. Full-array views retain their layer addressing.
 - A [depth surface](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) is retired when a color target or a written storage image it does not serve overlaps it, or when it is sampled through a view it cannot serve and guest memory over it was written since it was last bound; lookups then skip it, so sampling reads the memory like any texture. Bound again, it keeps its own depth instead of the bytes written over it. Without write watching, a view it cannot serve still throws. A retired surface also gives up its depth and stencil planes, so another surface sharing them no longer copies from it.

 - [Guest arena](../../../core/libs/prx/libc/src/GuestArena.cpp) (libc) - the application map area is assumed to end at 0xFC_0000_0000, as `SCE_KERNEL_APP_MAP_AREA_END_ADDR` does on the PS4. On Windows, host allocations made in the arena before libc loads stay, and a fixed guest mapping over one throws
 - [sceLibcInternalBacktraceForGame](../../../core/libs/prx/libc/src/HeapDiagnostics.cpp) (libSceLibcInternal, implemented in libc) - `(const char* heapName)` and its return follow the `libc.prx` ASTRO BOT (PPSA21564 01.007.000) bundles: its four calls (0x6801, 0x7F46, 0xE75E, 0xEE02) are in the `malloc_stats` and `sceLibcMspaceMallocStats` paths, each after a `[%s] ...` line printed with the same heap name buffer, and the caller ignores the result and continues. The console's backtrace output is not reproduced: the heap name and the guest return address are written to the host standard error
 - [sceLibcInternalHeapErrorReportForGame](../../../core/libs/prx/libc/src/HeapDiagnostics.cpp) (libSceLibcInternal, implemented in libc) - `(void* heap, void* block, uint32 error)` follows the same `libc.prx` (call at 0xF634): it passes the heap, the block and the nonzero result of its block check, and then calls a function that never returns, so the report only has to return. The meaning of the error values is unknown; the three values and the guest return address are written to the host standard error
+- [sceLibcPafMspaceCreate, Destroy, Malloc, Free, Calloc, Realloc, Reallocalign, MallocStats and MallocStatsFast](../../../core/libs/prx/libc/src/Mspace.cpp) (libSceLibcInternal, implemented in libc) follow the console's `libSceLibcInternal.sprx` (SDK 4.5x build of `J03950001`, 0x5D680 to 0x5D770): each calls the same internal routine as its `sceLibcMspace` counterpart without the malloc callback hook those add, and `Reallocalign` takes the alignment before the size as `sceLibcMspaceReallocalign` does. `Create` takes a fifth argument, a pointer to a creation options block (a version word, a type of 1 or 2 at offset 2, a field at 0x10) that the `Mspace` form passes as null; a non-null block throws, as its meaning is unknown. `Malloc`, `Free`, `Calloc`, `Realloc` and `Reallocalign` take a trailing owner value that the console XORs with its block magic and stores in each block's footer, where the `Mspace` forms pass the heap itself. Footers are not modelled here, so the owner is ignored. Measured on a PS5 (firmware 13.60) from a homebrew payload, the calls with a matching owner behave as here, but the console ends the process when `Reallocalign` is given a block whose owner differs and when it resizes a block in place with an owner other than the heap, and `MallocStats` returns 1 instead of 0 while the heap holds blocks owned by something other than the heap; none of this is reproduced. `PafMspaceMemalign`, `PosixMemalign`, `MallocUsableSize`, `Trim`, `IsHeapEmpty`, `CheckMemoryBounds`, `ReportMemoryBlocks` and `GetFooterValue` are not implemented
 - [malloc_usable_size](../../../core/libs/prx/libc/src/ApplicationHeap.cpp) (libc) - with the default allocator it returns the size the block was requested with (the range registered for it), not the rounded-up chunk size Sony's allocator reports; both satisfy "at least the requested size", and bytes past the request would not be write-watched. With an application allocator it calls entry 9 of the replacement table (`malloc_usable_size` in KytyPS5's `MallocReplace` order) and throws when the table leaves it null, like `malloc_stats_fast`
 - [malloc, calloc, realloc, memalign, aligned_alloc and reallocalign](../../../core/libs/prx/libc/src/FileAndHeap.cpp) (libc) - follow FreeBSD 11.4 `contrib/jemalloc/src/jemalloc.c` for failures, not measured on the console: a size the default heap rejects or the guest arena cannot place (including a `calloc` product that overflows) returns null with `errno` `ENOMEM`, and `memalign` and `aligned_alloc` return null with `EINVAL` for an alignment that is zero or not a power of two. FreeBSD's libc has no `memalign`, so setting `errno` there is assumed. A host commit failure for a block that fits in the arena (Windows `ERROR_NOT_ENOUGH_MEMORY`, `ERROR_OUTOFMEMORY` or `ERROR_COMMITMENT_LIMIT`, Linux `ENOMEM`) resets and releases the reserved range and returns null with `ENOMEM`; any other commit failure releases the range and throws. `reallocalign` returns null with `EINVAL` for an invalid alignment and `ENOMEM` like the others, which is an assumption as it is not in FreeBSD. `realloc(ptr, 0)` frees the block and returns null, where FreeBSD 11.4's jemalloc 4.5 resizes it to one byte and returns a block
 - [reallocf](../../../core/libs/prx/libc/src/FileAndHeap.cpp) (libSceLibcInternal, implemented in libc) - follows FreeBSD 11 `lib/libc/stdlib/reallocf.c` on top of this libc's `realloc`, not measured on the console: size 0 frees the block and returns null as `realloc` does here, so the block is not freed twice; when `realloc` fails because the application allocator returns null or the default heap rejects the size, the block is freed through the same allocator, `errno` is `ENOMEM` and null is returned. Other failures (a commit failure that is not out of memory, an unknown pointer) throw, as they do for `realloc`

Subject: [PATCH 0936/1000] fix(agc): keep robustBufferAccess2 off on AMD's
 proprietary driver

Since #4048 enabled robustBufferAccess2, AMD's Windows driver draws
nothing in agc_driver_layered_volume_draw and agc_driver_layered_volume_vertex,
and the selected loads make the high half of agc_driver_subvector_loop's
wave64 skip its loop. Until the cause is found, that driver does not get
the feature, and its loads keep their selections.

 - [Flag structurization](../../../core/shader/recompiler/ControlFlow/src/Structurizer.cpp) (shader recompiler) - a graph that every structurizer attempt refuses, irreducible and non-terminating graphs included, is rebuilt with one reach flag per block and one again flag per loop (`structurizeWithFlags`): each block keeps one copy and runs behind a guard on its flag, and each strongly connected component becomes a loop whose single latch repeats it while a back edge set its flag. The output has about 8 times the input's blocks and one route variable per block, and ends in an empty Return that never runs. Only blocks that start the top-level order unconditionally run unguarded, so resource planning also sees the static paths that skip a guarded block and can plan extra descriptor candidates for them. The attempts still run first. Shared merge splitting refuses an attempt once the graph has grown past 16 times its block count at the start of splitting (at least 64 blocks); succeeding attempts grew at most 10.6 times on random graphs of up to 128 blocks, and an attempt that would succeed only beyond the budget leaves the graph to a later attempt or to this construction. Splitting that adds one block per round stays within that budget until its 4 rounds per block run out, so the attempts can still take more than 10 s (9 of 2,000 random graphs of up to 128 blocks, 63 s at most). `APS5_FORCE_STRUCTURIZER_FALLBACK=1` builds every graph this way, for tests
 - [Scalar buffer descriptors](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) use only the base address, stride and record count for resources accessed exclusively by scalar loads; their fourth word is normalized to zero, following AMD RDNA2 ISA section 7.2.2. Vector and mixed accesses retain descriptor validation. Native Vulkan readbacks cover ignored fourth-word fields on Windows/NVIDIA; their console behavior has not been measured.
 - [Spanned wave64 compute](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvSubgroup.cpp) (shader recompiler) - `APS5_SPANNED_WAVE=1`, off by default, runs a single-wave wave64 compute program at one lane per invocation on a 32-lane host subgroup and exchanges ballots, shuffles and reductions between the two host subgroups through workgroup memory and barriers. The driver turns it on only where compute subgroups can be pinned at 32 full lanes (`subgroupSizeControl` and `computeFullSubgroups`), passes it as `SpirvTarget::spannedWaves` (part of the cache key and the serialized request), and creates the pipelines of spanned programs with `REQUIRE_FULL_SUBGROUPS`, since the lane number `SubgroupId * 32 + SubgroupLocalInvocationId` needs two full subgroups. Those barriers are correct only where every invocation of the workgroup reaches them, which holds for the guest's wave-uniform control flow. The emulated 64-bit LDS atomics ([LockedLdsUpdate](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp)) run only on the lanes the exec mask keeps, so their lock loop ballots within its own host subgroup, as its elect already does. Any other cross-lane exchange emitted inside per-lane control flow would hang a spanned wave in the same way, and the emitter does not reject one: there is no uniformity check. The only check so far is manual: disassemble the module (`spirv-dis`), list the selection and loop constructs that enclose each `OpControlBarrier`, and read the condition of each enclosing selection. In Ghost of Yōtei's program 0x80003af600 (PPSA26344), 108 of 111 barriers sat only in loops on wave-uniform conditions and 3 inside per-invocation conditionals, all in the lock loop. Other programs and titles have not been scanned. An earlier, cheaper ballot (one barrier instead of three) also lost the device for a reason that is not understood, which may be another barrier placement problem. Measured on an RTX 4090 (Windows): an offline replay of that program and two Yōtei runs that previously lost the device (NVIDIA TDR) now run past it, and [LdsMaskWaterfall.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/LdsMaskWaterfall.cpp) runs both modes and covers a half-inactive wave. Stray (PPSA02101) on Intel ANV and a Demon's Souls (PPSA01342) request replay showed no fault, before this fix
-- [Guest memory load guards](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - a guest load whose lane is inactive or whose address is out of bounds is still performed and its result replaced by 0 with `OpSelect`, instead of a selection per guard, when the load can be pointed at a location nothing writes: scratch reads its own element 0; storage buffers (direct buffers, GDS) read element 0xfffffffe, which `robustBufferAccess2` turns into a zero load with no memory access, so the extra read cannot race with a write the guarded program would not have raced with ([Vulkan memory model](https://docs.vulkan.org/spec/latest/appendices/memorymodel.html#data-race)). Without `robustBufferAccess2` ([VulkanDevice.cpp](../../../core/libs/prx/libSceAgcDriver/Execution/src/VulkanDevice.cpp) enables it when the device has it) those loads keep their selections; LDS loads, stores, atomics, formatted and physical-address (BDA) accesses always do. LDS keeps the branch because NVIDIA's compiler predicates a branched LDS load at no cost, while the select form costs about 2.5 instructions per dword and splits a `ds_read_b128` into four loads (RTX 4060 measurements by @karanvora2599 in #4048); Intel's static counts favour the select only for wide reads, and run time was not measured on either. The aligned high word of a misaligned-capable buffer read re-reads the low word's own element. A selection guard costs four blocks per lane half and the host compiler's time grows with the block count: PPSA11142's merged PSP vertex program (3176 ISA words, wave64) emitted 16,983 blocks and 1,710 conditional branches, 5,907 and 868 with the selects. `agc_guarded_memory_loads` traces the emitted loads in both device modes.

 - [posix_spawn and posix_spawnp](../../../core/libs/prx/libSceLibcInternal/Spawn.cpp) (libSceLibcInternal) throw: creating a child process is not supported. PPSA99305 (Dusklight) and PPSA99309 (Wind Waker) stop on `main` at unresolved import `44hlATrd47U` (`posix_spawnattr_init`); a run with this PR has not established how far either title gets, and process creation still throws. The attribute and file action calls keep FreeBSD 11.4's objects, so a real `posix_spawn` would have to apply them in the child. Null or uninitialized objects, which FreeBSD dereferences, throw.

Warnings go to the guest's current `stderr` prefixed with `__progname`, where FreeBSD's `warnx` keeps the `stderr` of its first call. A null `getopt` option string, a null argument vector or argument, a negative `optind` and an `optind` moved inside a pending permutation throw where FreeBSD faults. `getopt_long_only` is not exported. That the console's `libSceLibcInternal` uses this FreeBSD code is unverified
 - [sys_siglist and sys_nsig](../../../core/libs/prx/libSceLibcInternal/SignalList.cpp) (libSceLibcInternal) hold the 32 descriptions and the count of [FreeBSD 11.4](https://github.com/freebsd/freebsd-src/blob/8c639945a44588f6cfdddfb057bb5aad88735da0/lib/libc/gen/siglist.c#L73-L107) `siglist.c` (`NSIG` 32, signal 0 to `SIGUSR2`); the console's table was not read

For |x| > 1, the infinities and NaN, Sony's error helper raises `FE_INVALID` and sets `errno` to `EDOM` before returning `(x - x) / (x - x)`, so a NaN argument also sets `EDOM`; msun itself sets no `errno`. 20 million random arguments in (-1, 1) give the same bits as that code run on a Windows host. The result needs the x87 precision control at 64 bits, as FreeBSD amd64 starts threads (control word `0x37f`), but guest threads do not set it: on Windows a thread started by `_beginthreadex` runs at 53 bits (`0x27f`), where `asinl(0.75)` returns mantissa `0xd91a98ae3406e000` instead of `0xd91a98ae3406e041`.

For |x| > 1, the infinities and NaN, Sony's error helper raises `FE_INVALID` and sets `errno` to `EDOM` before returning `(x - x) / (x - x)`, and for |x| = 1 it raises `FE_DIVBYZERO` and sets `errno` to `ERANGE` before returning `x / 0`; msun itself sets no `errno`. That code, run on a Windows host, gives the same bits, `errno` and floating-point exceptions as this implementation for all 2^32 arguments; it was not run on Linux.

 - [getenv, setenv, unsetenv, putenv](../../../core/libs/prx/libc/src/Environment.cpp) (libc) keep one guest environment that starts empty, like the `environ` libkernel exports, and never reads or changes the host's. A title sees only the variables it sets itself; host variables such as `HOME` and `PATH` name host paths a guest cannot use (PS5MC, PPSA99420, exits with `XBMC_Run returned -1` when it gets the host's `HOME`). Whether the console starts a title with any variables set is not measured
+- [mergesort](../../../core/libs/prx/libc/src/FileAndHeap.cpp) (libSceLibcInternal, implemented in libc) checks its arguments like the console's `libSceLibcInternal.sprx` (SDK 4.5x build of `J03950001`, 0x762D0): an element size under 4 sets `errno` to `EINVAL` (22) and returns -1, an empty array returns 0, and a failed `malloc` of the count times the size plus 8 bytes returns -1. The sort is a stable bottom-up merge, not FreeBSD's natural merge with its insertion sort for short runs, so the comparator is called in a different order and number of times; the result is the same for a consistent comparator. A null base or comparator and a size product that overflows, which the console does not check, throw
 - On macOS the [write watch](../../../core/libs/prx/libc/src/GuestWriteWatch.cpp) write-protects watched pages and records the first write to each from a SIGBUS/SIGSEGV handler, because macOS has no counterpart to `userfaultfd` write-protect or `MEM_WRITE_WATCH`. The protection is real, so:
   - a system call that writes into a protected page fails with `EFAULT` instead of faulting. `GuestArena::HostWrite` lifts the protection for the calls it brackets (file reads and socket receives); a host call that writes guest memory without it (`clock_gettime` and the like into a watched page) fails;
   - code that changes the protection of watched pages, or maps over them, has to call `GuestWriteWatchProtectionChanged`, and code that asks the kernel for a page's protection has to ask `GuestWriteWatchProtection` first, since a watched page is read-only between a collection and the next write. Nothing calls either yet: the macOS memory paths are not in the tree;

 - [nan and nanf](../../../core/libs/prx/libc/src/Math.cpp) (libc) return fixed quiet NaN values (`0x7fc00000` and `0x7ff8000000000000`), ignoring the tag argument as observed in the console's `libc.prx` (both exports load a global constant via `mov rax,[rip+..]; vmovsd xmm0,[rax]; ret`); VLC (PPSA85300) stops on nanf at start-up after strsep.
 - [lgamma and signgam](../../../core/libs/prx/libc/src/Math.cpp) (libc) - `lgamma` returns the host's `lgamma` and stores the sign of Γ(x) in the exported `signgam` (NID `5gOOC0kzW0c`, starting at 0 as in FreeBSD 11's [`s_signgam.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/msun/src/s_signgam.c)) by the rules of [`e_lgamma_r.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/msun/src/e_lgamma_r.c): -1 for -0 and for a negative non-integer whose floor is odd, 1 otherwise, including poles, infinities and NaN. Taken from the FreeBSD source, not measured on the console. The NID is in the aerolib symbol list; no title is known to read `signgam`. PPSA99004 imports `lgamma`
 - [sinhf](../../../core/libs/prx/libc/src/Math.cpp) (libc) follows the `sinhf` of the `libc.prx` bundled with PPSA28319 (disassembly): FreeBSD msun's [`e_sinhf.c`](https://github.com/freebsd/freebsd-src/blob/5aa554c7e5b6fd9042986df07f12ac5687e41392/lib/msun/src/e_sinhf.c) from before `__ldexp_expf`, which squares `expf(|x| / 2)` between `logf(FLT_MAX)` and the overflow threshold, calling msun's [`expm1f`](https://github.com/freebsd/freebsd-src/blob/59bc2f095289a10b8cfa55cbb2b45c3bd6c2d4ae/lib/msun/src/s_expm1f.c) and [`expf`](https://github.com/freebsd/freebsd-src/blob/59bc2f095289a10b8cfa55cbb2b45c3bd6c2d4ae/lib/msun/src/e_expf.c), whose paths for the arguments it passes are inlined here. Past the threshold Sony's error helper sets `errno` to `ERANGE` before returning `x * 1e37`; msun itself sets no `errno`. That code, run on a Windows host, gives the same bits as this implementation for every finite argument up to the threshold, of both signs; it was not run on Linux. That the system `libSceLibcInternal`, which Ruffle (PPSA68091) and RetroArch (PPSA99169) import while bundling a zero-return `libc.prx`, has the same code is assumed
+- [acoshl, asinhl, atanhl, atan2l, cbrtl, erfl, erfcl, expm1l, hypotl, log1pl, log2l, lgammal, tgammal, j0f, j1f, jnf, y0f, y1f and ynf](../../../core/libs/prx/libc/src/Math.cpp) (libc) return the host C library's results (the float Bessel functions through its double ones), not those of the console's own code, so the last bits can differ. As in the console's `libSceLibcInternal.sprx` (SDK 4.5x build of `J03950001`, 0x56410), `lgammal` does not store the sign in `signgam`; `hypotl` returns infinity for an infinite argument even when the other is a NaN, as C11 F.10.4.3 requires. [hypot3, hypot3f and hypot3l](../../../core/libs/prx/libc/src/Math.cpp) follow that module (0x51D30, 0x520D0, 0x52420): the first NaN of x, y and z is returned unchanged, any infinity gives positive infinity, a zero argument gives the two-argument hypot of the other two, and otherwise the largest magnitude is combined with the hypot of the other two
 - [asinl](../../../core/libs/prx/libc/src/Math.cpp) (libc) follows the `asinl` of the `libc.prx` bundled with PPSA28319 (disassembly), FreeBSD msun's [`e_asinl.c`](https://github.com/freebsd/freebsd-src/blob/9f0432041b8fb69832f10c32da50a67f34feeb61/lib/msun/src/e_asinl.c) with the ld80 [`invtrig.c`](https://github.com/freebsd/freebsd-src/blob/9f0432041b8fb69832f10c32da50a67f34feeb61/lib/msun/ld80/invtrig.c) coefficients, which the binary holds as the same 80-bit constants. For |x| > 1, the infinities and NaN, Sony's error helper raises `FE_INVALID` and sets `errno` to `EDOM` before returning `(x - x) / (x - x)`, so a NaN argument also sets `EDOM`; msun itself sets no `errno`. 20 million random arguments in (-1, 1) give the same bits as that code run on a Windows host. The result needs the x87 precision control at 64 bits, as FreeBSD amd64 starts threads (control word `0x37f`), but guest threads do not set it: on Windows a thread started by `_beginthreadex` runs at 53 bits (`0x27f`), where `asinl(0.75)` returns mantissa `0xd91a98ae3406e000` instead of `0xd91a98ae3406e041`. The system `libSceLibcInternal` that RetroArch (PPSA99169) imports is assumed to have the same code
 - [atanhf](../../../core/libs/prx/libc/src/Math.cpp) (libc) follows the `atanhf` of the `libc.prx` bundled with PPSA28319 (disassembly): FreeBSD msun's [`e_atanhf.c`](https://github.com/freebsd/freebsd-src/blob/59bc2f095289a10b8cfa55cbb2b45c3bd6c2d4ae/lib/msun/src/e_atanhf.c) calling msun's [`log1pf`](https://github.com/freebsd/freebsd-src/blob/59bc2f095289a10b8cfa55cbb2b45c3bd6c2d4ae/lib/msun/src/s_log1pf.c), whose paths for the positive arguments it passes are inlined here; the exported `log1pf` is still the host's. For |x| > 1, the infinities and NaN, Sony's error helper raises `FE_INVALID` and sets `errno` to `EDOM` before returning `(x - x) / (x - x)`, and for |x| = 1 it raises `FE_DIVBYZERO` and sets `errno` to `ERANGE` before returning `x / 0`; msun itself sets no `errno`. That code, run on a Windows host, gives the same bits, `errno` and floating-point exceptions as this implementation for all 2^32 arguments; it was not run on Linux. That the system `libSceLibcInternal`, which Dusklight (PPSA99305) imports while bundling a zero-return `libc.prx`, has the same code is assumed
 - [getenv, setenv, unsetenv, putenv](../../../core/libs/prx/libc/src/Environment.cpp) (libc) keep one guest environment that starts empty, like the `environ` libkernel exports, and never reads or changes the host's. A title sees only the variables it sets itself; host variables such as `HOME` and `PATH` name host paths a guest cannot use (PS5MC, PPSA99420, exits with `XBMC_Run returned -1` when it gets the host's `HOME`). Whether the console starts a title with any variables set is not measured

 - [getifaddrs](../../../core/libs/prx/libc/src/Interfaces.cpp) (libc) lists the host's IPv4 and IPv6 addresses in FreeBSD's `ifaddrs` and sockaddr layouts. FreeBSD's per-interface AF_LINK entries (MAC, index, MTU) and their `if_data` are not produced, so interfaces without an address are omitted. Names are the host's (Linux `lo`, `eth0`; Windows NDIS names such as `ethernet_32769`, or `if<index>` when one does not fit 15 bytes), not the console's. A Linux point-to-point address without a peer loses `IFF_POINTOPOINT`, and an IPv4 broadcast address the host omits is computed from the netmask. On Windows the flags are only `IFF_UP`, `IFF_RUNNING`, `IFF_LOOPBACK`, `IFF_BROADCAST` and `IFF_MULTICAST`, derived from the adapter: PPP and tunnel adapters get neither `IFF_BROADCAST` nor `IFF_POINTOPOINT` because their peer address is not reported, and an address whose prefix length the host reports as unspecified gets a host mask.
 - [gethostname](../../../core/libs/prx/libc/src/Hostname.cpp) (libc) reports the fixed guest name `AnyPS5` without querying the host machine name. Buffer copying, null queries and `ENAMETOOLONG` follow [FreeBSD gethostname](https://github.com/freebsd/freebsd-src/blob/main/lib/libc/gen/gethostname.c); the console's configurable hostname and its integration with `sysctl` and name resolution are unverified and not implemented.
 - [wcsrtombs_s](../../../core/libs/prx/libc/src/Multibyte.cpp) (libc) follows the console's `libc.prx`, but a runtime-constraint violation only returns its error: the default handler there writes the message and a newline to `stderr` before returning, which is not done here. Conversion uses the C locale of `wcrtomb` (`MB_CUR_MAX` 1), so the path where a multibyte character does not fit the remaining space is not reached
+- [c16rtomb, c32rtomb, mbrtoc16 and mbrtoc32](../../../core/libs/prx/libc/src/Multibyte.cpp) (libSceLibcInternal, implemented in libc) follow the console's `libSceLibcInternal.sprx` (SDK 4.5x build of `J03950001`, 0x7D480 to 0x7D920), which converts to and from UTF-8 whatever the locale, with the original sequences of up to six bytes and no check for surrogates or for values above 0x10FFFF when encoding. The conversion state keeps the value in its first eight bytes and the count of bytes still expected (or 0x10 for a pending low surrogate, 1 for a stored high surrogate) as 16 bits at offset 0xA; a null state, which the console dereferences, throws. As on the console, `mbrtoc16` does not store the complete code point when it returns a high surrogate, so the low surrogate of the next call is built from the value the state last held, which is the partial value of an earlier incomplete call or whatever the caller initialised it to, `c16rtomb` returns -1 without setting `errno` when a high surrogate is not followed by a low one, and `mbrtoc16` and `mbrtoc32` report `EILSEQ` as 86. Measured on a PS5 (firmware 13.60) from a homebrew payload, the system `libSceLibcInternal`'s default locale also converts UTF-8 in `wcrtomb`, `wctomb`, `mbrtowc` and `mblen` (`wctomb` of U+263A gives `E2 98 BA`, `mblen` of a lone 0xE9 gives -1); this libc keeps its single-byte C locale, so [wctomb and mblen](../../../core/libs/prx/libc/src/Multibyte.cpp), which call `wcrtomb` and `mbtowc` here as they call the same internal routines on the console, share that difference. Titles bundle their own `libc.prx`, whose locale was not measured
 - [The narrow printf family](../../../core/libs/prx/libc/src/Formatting.cpp) (libc) converts 16-bit guest wide arguments to UTF-8 on both platforms, independently of the host locale. It does not use the guest's single-byte `wcrtomb`; the console's treatment of invalid UTF-16 and locale-specific encoding remains unverified. Linux retains host formatting for formats without wide arguments or `%m`, so a narrow `%p` and a NaN there still follow the host (glibc prints a null pointer as `(nil)`, where FreeBSD prints `0x0`, and a NaN with its sign, `-nan`, and with the `+` and space flags, where FreeBSD prints `nan`); argument positions above 99 (FreeBSD's `NL_ARGMAX`) throw when a format requires the guest formatter
 - [collate<char> and collate<wchar_t> _Getcat](../../../core/libs/prx/libc/src/LocaleSupport.cpp) (libc) build the facet for the C locale only and throw for any other locale name, the wide entry point following the narrow one it sits next to. The wide facet carries its own vtable, whose `compare`, `transform` and `hash` take the guest's 16-bit characters, so the length of a range is a count of characters: `compare` orders by 16-bit value (the C locale, as Dinkumware's `char_traits<wchar_t>::compare` does), `transform` copies the characters into the result and records size and capacity in 16-bit elements (inline capacity 7, heap capacity `length | 7`, `(capacity + 1) * 2` bytes including the terminator), following Dinkumware's [VC12 `basic_string`](https://github.com/ganboing/crt.vc12/blob/f1d47126bf13d1c9dccaa6c53b72217fd0474968/src/xstring#L500-L531), and `hash` mixes one whole character per round, so wide text below 0x100 hashes like its narrow spelling and a character above 0xff hashes as one value instead of the two bytes it holds. The console's `libc.prx` exports both `_Getcat` (NIDs BSVJqITGCyI and 2wz4rthdiy8) with identical 0x19d-byte bodies, believed to build the same 0x20-byte facet; the console bodies themselves are unreadable (obfuscated dynsym, and the text of the relinked `libc.prx` is zeroed), so the wide entries follow the narrow algorithm and the C locale instead of the console's wide code, and no console run checks the two. The console's `libc.prx` stores pointers to its collation state tables at offsets 0x10 and 0x18 of the facet; ours leaves them null, as only the facet's own functions read them. `do_transform` throws for input with embedded null characters, which the console drops depending on the output buffer size. The narrow result capacity (`length | 15`) and the over-aligned storage of results of 4080 characters or more follow the console's `libc.prx` code and are not checked on hardware. No module of the PPSA59322, PPSA76677 or PPSA97358 dumps in this tree imports either `_Getcat`, so neither has been exercised by a title.
 - [The scanf family](../../../core/libs/prx/libc/src/Formatting.cpp) (libc), the `_s` forms included, on Linux throws for the 16-bit wide conversions (`%ls`, `%lc`, `%l[`, `%S`, `%C`): glibc would store a 32-bit `wchar_t` per character into the guest's 16-bit buffer. Windows hands `%ls`, `%lc` and `%l[` to the host, whose `wchar_t` is 16 bits

 - [realpath](../../../core/libs/prx/libc/src/RealPath.cpp) (libc) follows FreeBSD 11's [`realpath.c`](https://github.com/freebsd/freebsd-src/blob/stable/11/lib/libc/stdlib/realpath.c) except for symlinks. The console's guest filesystem has none, so a host symlink under the guest root is followed for existence and type but not expanded, and `..` drops the previous component lexically, as `Resolve` does for every guest path. Through a host link `linkdir -> sub/deep`, `linkdir/../x` gives `x` beside the link, not beside its target.
 - [strtod, strtof, strtold](../../../core/libs/prx/libc/src/Strings.cpp) (libc) - `NAN(n-char-sequence)` converts to the quiet NaN that `nan` and `nanf` return, negated after a minus sign, and ignores the sequence as they ignore their tag. This is inferred from C17 7.12.11.2p2, which makes `nan("n")` equivalent to `strtod("NAN(n)", NULL)`, and not observed on the console. No console `nanl` was observed, so `strtold` returns the x87 default quiet NaN (exponent `0x7fff`, significand `0xc000000000000000`)
 - [nan and nanf](../../../core/libs/prx/libc/src/Math.cpp) (libc) return fixed quiet NaN values (`0x7fc00000` and `0x7ff8000000000000`), ignoring the tag argument as observed in the console's `libc.prx` (both exports load a global constant via `mov rax,[rip+..]; vmovsd xmm0,[rax]; ret`); VLC (PPSA85300) stops on nanf at start-up after strsep.
+- [seed48 and lcong48](../../../core/libs/prx/libc/src/Random.cpp) (libSceLibcInternal, implemented in libc) follow the console's `libSceLibcInternal.sprx` (SDK 4.5x build of `J03950001`, 0x6F460 and 0x6F420): the multiplier and addend are shared by the whole `rand48` family, including `erand48`, `nrand48` and `jrand48` on a caller's seed; `lcong48` sets them with the seed, and `srand48` and `seed48` restore 0x5DEECE66D and 0xB. Unlike FreeBSD, `seed48` returns a static copy of the new seed rather than the previous one. A null argument, which the console dereferences, throws

Taken from the FreeBSD source, not measured on the console. The NID is in the aerolib symbol list; no title is known to read `signgam`. PPSA99004 imports `lgamma`

Past the threshold Sony's error helper sets `errno` to `ERANGE` before returning `x * 1e37`; msun itself sets no `errno`. That code, run on a Windows host, gives the same bits as this implementation for every finite argument up to the threshold, of both signs; it was not run on Linux. That the system `libSceLibcInternal`, which Ruffle (PPSA68091) and RetroArch (PPSA99169) import while bundling a zero-return `libc.prx`, has the same code is assumed
 - [asinl](../../../core/libs/prx/libc/src/Math.cpp) (libc) follows the `asinl` of the `libc.prx` bundled with PPSA28319 (disassembly), FreeBSD msun's [`e_asinl.c`](https://github.com/freebsd/freebsd-src/blob/9f0432041b8fb69832f10c32da50a67f34feeb61/lib/msun/src/e_asinl.c) with the ld80 [`invtrig.c`](https://github.com/freebsd/freebsd-src/blob/9f0432041b8fb69832f10c32da50a67f34feeb61/lib/msun/ld80/invtrig.c) coefficients, which the binary holds as the same 80-bit constants. For |x| > 1, the infinities and NaN, Sony's error helper raises `FE_INVALID` and sets `errno` to `EDOM` before returning `(x - x) / (x - x)`, so a NaN argument also sets `EDOM`; msun itself sets no `errno`. 20 million random arguments in (-1, 1) give the same bits as that code run on a Windows host. The result needs the x87 precision control at 64 bits, as FreeBSD amd64 starts threads (control word `0x37f`), but guest threads do not set it: on Windows a thread started by `_beginthreadex` runs at 53 bits (`0x27f`), where `asinl(0.75)` returns mantissa `0xd91a98ae3406e000` instead of `0xd91a98ae3406e041`. The system `libSceLibcInternal` that RetroArch (PPSA99169) imports is assumed to have the same code

Subject: [PATCH 0943/1000] perf(shader): initialize the sRGB decode table once
 per module

DecodeSrgbTexel looked up the 256 table constants and stored the whole
table into its Private array at every decode site. The constants are
interned, but once a module has more than the declaration cache's 512
entries, each of those lookups that misses walks every slot before it
reaches the map. The table is now built on first use as the Private
array's initializer, as the buffer format table already is, and later
sites only index it.

The sRGB image load test checks that the recompiled module holds one
table, initializes one variable with it and never stores it.

Subject: [PATCH 0944/1000] fix(test): sample the anisotropic min/max rows
 without a mip filter

The two anisotropic rows of agc_driver_image_sample_reduction sampled
a two-level texture at explicit LOD 0.25 and 0.75 through a point mip
filter, and expected only the nearest level in the min or max. Vulkan
leaves the anisotropic filtering scheme to the implementation, and
only recommends that it consider mipmapMode, minLod and maxLod. On an
RTX 4090 (NVIDIA 616.92) the min row returns 5, a level-1 texel, where
level 0's bilinear minimum is 17, so the test fails on main there.

The rows now use no mip filter, which the decoder turns into a host
sampler with minLod and maxLod 0, so they read level 0 only, as the
RDNA2 measurements without derivatives did (gfx1030 with no mip filter
over a single-level texture, gfx1035 with image_sample_lz). They still
throw if the min or max reduction with anisotropy is refused again.

 - [HTILE depth fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - HTILE is not modeled. Only RADV's `clear_htile_mask` compute kernel (17 GFX10 words, 64x1x1 groups) is recognized, and only when it leaves ZMASK at 0 (`user[4]` and `user[5]` low nibbles both 0); the dispatch still runs, and the host depth image is cleared to `DB_DEPTH_CLEAR` the next time the surface with that `DB_HTILE_DATA_BASE` address is bound. The address match is exact, so a clear of a different HTILE range does not hit. HTILE initialization, the stencil-only update, and fast clears made by the SDK's own paths, CP DMA fills or other kernels are not covered and leave the depth image as it was. The kernel words are the ones the PR author saw RADV submit; they are not compared with Mesa's source. A second kernel, the 9-word dword fill PPSA01802 (Kena: Bridge of Spirits) clears its depth HTILE with (64x1x1 groups, one `buffer_store_format_x` per thread through the stride-4 V# in `user[0..3]`, the value read by `s_buffer_load_dword` through the V# in `user[4..7]`), is taken as a fill of that range when the store format is 32_UINT, 32_SINT or 32_FLOAT and the value V# covers the dword (NUM_RECORDS times its stride, or NUM_RECORDS bytes when the stride is 0) ([`MatchMemoryValueFill`](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp), then the whole-HTILE and ZMask rules of `NoteDepthMetadataFill`). The value is read from guest memory when the dispatch is decoded, so a value that earlier GPU work in the same submission has not written back yet is not seen. When the [fill HLE](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Memory/BufferFill.cpp) takes the dispatch instead (an output descriptor of one 32-bit value per element, a value descriptor that covers the loaded dword, a 16-byte aligned range), the value is read again when the fill is recorded, after the labels queued before it, and the HTILE fill is noted with that value.
 - [HTILE written by other kernels](../../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp) (libSceAgcDriver) - when a depth target is bound and its HTILE was written since it was last read, the words over its whole pipe-aligned metadata (`HtileMetadataBytes`, the extent `HtileFillCovers` takes) are read, outside the surfaces mutex since the read waits for recorded work: when every one marks the depth (ZMask 0) or the stencil (SMem 0) cleared, the surface takes that fast clear and the words are stored back as expanded (depth only: ZMask 15 over the full Z range; with stencil: ZMask 15, Z range and SMem, SR1 and SR0 3), so only the title's next clear clears it again. PPSA29141 clears its depth every frame with a compute kernel the fill hooks do not recognize (`InvokeHTileClearComputeShader` in its `ClearMRT` pass); without this its depth kept every earlier frame and moving objects left black trails. PPSA25344 (Unreal Engine 5) reads its HTILE after the depth prepass in its Nanite depth export, which takes a tile with ZMask 0 as holding the clear value; without the expanded words the export put Nanite depth over the prepass and the Nanite material pass painted over the meshes in front. The word layouts are Mesa radv's for GFX10. Metadata with some tiles cleared is not modelled, and the compression state draws leave in HTILE is not tracked, so a title reading its HTILE after a draw sees the stored expanded words. A recognized HTILE fill or clear makes the next bind read the words again. A slice other than 0 of a depth array is read at its own HTILE (`DB_HTILE_DATA_BASE` plus the slice times `HtileMetadataBytes`) but the HTILE word layout of slices 1 and up is not modelled (PPSA05684's tile masks need X8 and Y8 to take Z0 and Z1 as well, slices 4 and up unmeasured), so such a slice takes the clear only when all its words are equal and otherwise keeps the fill-time fast clears. A depth-only HTILE whose tiles all have ZMask 0 but different Min/Max Z (per-tile clear values, PPSA05684's cascades) is taken as a whole-surface clear to `DB_DEPTH_CLEAR`. A multisampled depth target, and any target whose HTILE overlaps a resident native depth guard, skips this read and store-back and goes to the native multisample depth owner, which keeps its own refusal for a fast-clear transition.
 - [Host imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver) on Linux skip ranges that are not mapped read-write, which are copied instead. The NVIDIA driver (595.91.07) refuses `VK_EXT_external_memory_host` imports of read-only or executable mappings (and shared mappings of regular files) with `VK_ERROR_OUT_OF_DEVICE_MEMORY`, after which every `vkAllocateMemory` on the device fails the same way. Read-only ranges are never imported, even on drivers that accept them. Shared mappings of regular files are not checked for. On Windows, an alias of adjacent registered ranges is refused if any page is not a shared view; a range made entirely of shared views is aliased run by run, including across sections or nonconsecutive section offsets. Adjacent registered ranges are joined into one import where they fill a whole 8 MiB aligned window; ranges of a partly filled window, and ranges larger than the window, are imported one at a time. A buffer bound across adjacent ranges that are each larger than the window, or bound exactly over adjacent ranges of any size (from the first one's start to the last one's end), joins them into one import when it is bound, and their own imports are retired; a buffer that crosses any other two imports is copied. A heap grown in pieces re-imports its joined run only when a buffer is bound exactly over all of its pieces, or when a sparse descriptor heap over it is bound: a heap a shader binds whole while only the pieces from its base are mapped is bound in place from the import of that run, its views ending at the import's end as the copy's do, once the previous bind of that address saw the same last mapped byte (a heap that grows between every two of its binds stays copied; one bound more often than it grows is joined again after each growth) and at most 64 times per joined run base; past that, with a message, it is not joined again: it is bound in place while an existing import covers its run and copied otherwise, until no registered range starts at that base or the device changes. Ranges larger than the window are taken to be registered whole and never grown in pieces: a title that grows a heap in pieces larger than 8 MiB re-imports the joined run each time a bound buffer crosses into a new piece. The 8 MiB window is a choice: unbounded runs were re-imported whole on every growth of a heap mapped in small pieces, and the NVIDIA driver (610.57.04, 615.78.08) then refused imports or lost the device. Not measured on RADV.

Subject: [PATCH 0946/1000] fix(libkernel): fail sigprocmask with EINVAL for an
 unknown how

sigprocmask and _sigprocmask threw std::invalid_argument for a how other
than SIG_BLOCK, SIG_UNBLOCK or SIG_SETMASK, which ends the title. FreeBSD
returns -1 with EINVAL and leaves the old mask uncopied, and ignores how
when set is null; pthread_sigmask here already returns EINVAL. The check
now comes first, before the previous mask is written.

Subject: [PATCH 0947/1000] fix(libkernel): answer a join of the calling thread
 before its detach state

scePthreadJoin checked whether the thread was detached before whether it
was the calling thread. So a detached thread joining itself got EINVAL
instead of EDEADLK, and so did the main thread, which scePthreadSelf
adopts as detached. FreeBSD's join checks the calling thread right after
the null check and before it looks at the detach state. The self check
now comes first; the null, detached and already-joined answers are
unchanged.

Subject: [PATCH 0948/1000] fix(shader): use 64-bit buffer atomics for
 device-memory LDS

Compute LDS beyond the device's shared-memory limit lives in a storage
buffer, and its 64-bit atomics took a lock in that buffer. AMD's Windows
driver compiles the lock's acquire and release to s_barrier, which inside
the divergent lock loop pairs with the program's own barriers, so the
device-memory case of agc_driver_lds_lock_budget read half its sum.

With shaderBufferInt64Atomics the device-memory LDS now uses a 64-bit view
of the buffer instead: 64-bit atomics are compare-exchange loops on it and
32-bit atomics stay native, so no lock is taken. Without the feature the
lock is kept. The per-workgroup slice is rounded up to an even dword count
so that the 64-bit view stays aligned.

 - [Unused pixel programs](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver): a bound pixel program is skipped when color masks have no intersection and DB export and execution enables are clear, regardless of retained SPI_SHADER_Z_FORMAT. This follows [AMD PAL DbShaderControl](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/hw/gfxip/gfx9/gfx9AbiToPipelineRegisters.h) and its [GFX10 register definitions](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/hw/gfxip/gfx9/chip/gfx9_plus_merged_registers.h), not a hardware measurement. Enabled DB_ALPHA_TO_MASK conservatively retains the program even with ALPHA_TO_MASK_DISABLE, because DecodeState currently enables Vulkan alpha-to-coverage without applying that override. Console behavior for these combinations has not been measured.
 - [Sample masks](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - `PA_SC_AA_MASK_X0Y0_X1Y0` and `PA_SC_AA_MASK_X0Y1_X1Y1` hold one 16-bit sample mask for each pixel of the aligned 2x2 quad ([Mesa gfx10.json](https://gitlab.freedesktop.org/mesa/mesa/-/blob/7b87f8ad226e/src/amd/registers/gfx10.json#L13512)); only the bits of the `MSAA_NUM_SAMPLES` rasterized samples count, and at one sample bit 0 of a pixel's field covers every sample of the target the draw is raised to. A mask equal for the four pixels is the Vulkan `pSampleMask`, the case [radv](https://gitlab.freedesktop.org/mesa/mesa/-/blob/7b87f8ad226e/src/amd/vulkan/radv_cmd_buffer.c#L13633) and [radeonsi](https://gitlab.freedesktop.org/mesa/mesa/-/blob/7b87f8ad226e/src/gallium/drivers/radeonsi/si_state.c#L4218) program; with early fragment tests it needs `earlyFragmentSampleMaskTestBeforeSampleCounting` ([radv](https://gitlab.freedesktop.org/mesa/mesa/-/blob/7b87f8ad226e/src/amd/vulkan/radv_physical_device.c#L2079) reports it). A mask that differs between the pixels is applied in the pixel shader without early fragment tests: a pixel whose mask covers all or none of its samples is demoted to a helper invocation by `gl_FragCoord` parity, and otherwise the pixel's mask is ANDed into `gl_SampleMask` (with alpha-to-coverage and the mask export) after demoting invocations whose `SampleMask` input it leaves empty. A pixel program with early Z that writes memory under depth, stencil or depth-bounds tests is therefore refused. That XnYm is the pixel at (x mod 2, y mod 2) = (n, m) is read from the field names; that the mask removes samples before the depth and stencil tests and occlusion counting is inferred from radv implementing the Vulkan sample mask test with it; and that it takes no part in the centroid (`AA_MASK_CENTROID_DTMN` 0) is inferred from radv setting that bit only for conservative rasterization. None of it is measured on gfx1013. A mask equal for the four pixels that removes some but not all samples of a pixel is refused with active centroid inputs, since where Vulkan puts the centroid relative to `pSampleMask` is implementation-defined, and any partial mask is refused with conservative rasterization (radv sets `PREZ_AA_MASK_ENABLE` and `POSTZ_AA_MASK_ENABLE` [there](https://gitlab.freedesktop.org/mesa/mesa/-/blob/7b87f8ad226e/src/amd/vulkan/radv_cmd_buffer.c#L13653), which 0x6001 leaves clear).
 - [Covered-centroid raster state](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) accepts PA_SC_AA_CONFIG.COVERED_CENTROID_IS_CENTER only when the pixel program is skipped or SPI_PS_INPUT_ENA and SPI_PS_INPUT_ADDR have no active perspective or linear centroid input. Bit 29 follows [PS5_Mesa GFX10.3 registers](https://github.com/mihawk-99/PS5_Mesa/blob/0b2d6d1a61d9bbf89cf8beb88a696144f67c61f8/src/amd/registers/gfx103.json); [RADV](https://github.com/mihawk-99/PS5_Mesa/blob/0b2d6d1a61d9bbf89cf8beb88a696144f67c61f8/src/amd/vulkan/radv_cmd_buffer.c) sets it on GFX10.3 and later.

 - [AGC buffer allocations](../../../core/libs/prx/libSceAgcDriver/Graphics/src/BufferPool.cpp) retry host/device out-of-memory once after reclaiming idle pool buffers and fully unused slab blocks. Live buffers and blocks with live slots are retained. Live images and other retained resources have no global memory bound; allocation failure still throws when reclaim cannot satisfy the request.
 - [Pipeline journal](../../../core/libs/prx/libSceAgcDriver/Graphics/src/PipelineJournal.cpp) (libSceAgcDriver): the journal is append-only and never compacted, so a module a later run no longer builds pipelines from stays in the file until it is deleted, and the whole file is read into memory while the replay runs (its modules reference that buffer until the last replayed pipeline was built). Only the first `APS5_PIPELINE_JOURNAL_ENTRIES` pipelines recorded are replayed (a record is never rewritten, so a pipeline past the bound stays past it), and the pipeline store evicts the least recently used entry past `APS5_PIPELINE_STORE_ENTRIES` (1024 each): a title with more configurations rebuilds the rest at the draw as before. A compute pipeline is replayed over the set layout `DescribeSetLayouts` derives from the result's bindings, which a dispatch that finds it resident checks against its `ShaderResources` layout only under `APS5_VERIFY_SET_LAYOUTS=1`. Recording and replay are best effort: a record whose write fails is lost, an entry whose build fails is skipped, and both are counted in the `[pipeline-journal]` line rather than stopping the run. A replayed pipeline that the title never asks for again costs its build time and its driver memory (its optimized relink is deferred to its first draw, so a run whose first frames bind many replayed pipelines queues their relinks then); nothing ages recipes out of the file. Two runs sharing the file take turns under its lock file, but each only knows the modules it loaded or wrote itself, so a module the other run appended meanwhile may be appended again (the loader keeps the first copy). Records a run appends after another run's load are replayed by that run only after its next start. The file header's format number is the only guard against a change of the recipe codec, `CanonicalPipelineState` or the store key that keeps the structures' sizes (the recompiler's source version does not cover the driver's sources).
 - [Graphics pipeline libraries](../../../core/libs/prx/libSceAgcDriver/Graphics/src/PipelineLibrary.cpp) (libSceAgcDriver): a pipeline is fast-linked at the draw and relinked with `VK_PIPELINE_CREATE_LINK_TIME_OPTIMIZATION_BIT_EXT` on a background thread, and binds the optimized one from the next draw on. Draws recorded before that use the fast link, whose vertex stage keeps the outputs the fragment stage does not read: on RADV (Radeon 660M, Mesa 26.2.4) 346 of 483 Astro's Playroom vertex shaders paired with a fragment stage that reads none of them used more VGPRs (median 8 more, up to 2.5 times), and on an RTX 4090 13 of 15 PPSA36082 vertex shaders up to 68 instead of 38 (#2242). The optimized link compiles to the same code as a whole pipeline

When the LDS lives in device memory (compute LDS beyond the device's shared-memory limit) and the device has `shaderBufferInt64Atomics`, no lock is used: a 64-bit atomic is a compare-exchange loop on a 64-bit view of the storage buffer and a 32-bit atomic is a native buffer atomic, so a mixed-width pair on one slot relies on the device ordering both widths on one buffer address; only `ds_add_u32` against `ds_add_u64` was measured, on gfx1036 (AMD Windows driver 32.0.21042.62) and an RTX 4070 SUPER. The lock is not used there because AMD's Windows driver compiles an acquire or release on a storage buffer, at workgroup scope or wider, to `s_barrier`, and those barriers inside the lock's divergent loop pair with the program's own `s_barrier`s. The fence after each LDS atomic compiles to `s_barrier` on that driver as well, so a wave that skips an LDS atomic that other waves of its workgroup execute misses a barrier they reach; its effect was not measured. On that path a 64-bit atomic at an address that is 4-byte but not 8-byte aligned is skipped and returns 0.

The returned value is always the old value as it was in memory. `IEEE_MODE` has no effect. The same bit rule serves the buffer float atomics (`AtomicFloatBits`). Not measured: a denormal or signalling-NaN `data1` of `cmpst` (stored as given). `ds_add_f32` and `ds_add_rtn_f32` follow RDNA1 (gfx1010, RX 5700 XT), measured with the [hardware oracle](../HW_ORACLE.md) template run through the Windows driver's comgr and HIP runtime over 1574 operand pairs (signed zeros, denormals, the smallest normals, infinities, quiet and signalling NaNs with payloads, the largest normals, random pairs near the denormal range and pairs that nearly cancel) in all 16 combinations of the f32 denormal field and the f32 round mode, and at IEEE 1 and DX10 clamp 0: both operands are flushed to a signed zero when bit 0 of the field is clear and the result when bit 1 is clear, the sum is rounded to nearest even whatever the round mode, a NaN data operand is stored quieted, else a NaN old value is stored quieted, `+inf + -inf` stores 0xffc00000, and `IEEE_MODE` and `DX10_CLAMP` have no effect. The sum is the host's `OpFAdd` between those flushes, so where the field keeps f32 denormals the result also depends on the host preserving them, which the module does not request. thuanquang measured the same rule on RDNA2 (gfx1031, RX 6700 XT) in #5492, with the same operand classes and 18 modes in wave32 and wave64; the PS5's gfx1013 is not measured.
 - [LDS in pixel, vertex-path and fetch programs](../../../core/shader/recompiler/SpirvBackend/src/SpirvAnalysis.cpp) (shader recompiler) - is an array private to each host invocation, in `Function` storage, as only compute and mesh programs get workgroup memory; on the console one LDS region is shared by the wave (RDNA 2 ISA sections 3.6.6 and 10.4), so a lane does not see another lane's LDS writes. Sub-dword writes (`ds_write_b8`, `ds_write_b16` and their `_d16_hi` forms), the 32-bit LDS atomics, `ds_append` and `ds_consume` load, update and store the invocation's own dword without an atomic, as Vulkan allows atomics only on `Uniform`, `Workgroup`, `Image`, `StorageBuffer`, `PhysicalStorageBuffer` and `TaskPayloadWorkgroupEXT` pointers (VUID-StandaloneSpirv-None-04686). `ds_append` and `ds_consume` update only the first active lane's copy and return its old value to every lane, so a second append after the first active lane changes, or a read of the counter by another lane, differs from the hardware. Not measured on hardware.
 - [V# bases off a DWORD boundary](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - raw accesses use the exact bytes and `s_buffer_load` reads `(base & ~3) + (offset & ~3)`, as measured on gfx1035 (Linux, alignment mode UNALIGNED; the console's mode is unknown). Formatted accesses off their element's alignment throw. Atomics use the byte address `base + offset`, base's low two bits included: measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) with `buffer_atomic_add`, `buffer_atomic_swap` and `buffer_atomic_cmpswap` and bases 0 to 3 bytes past a DWORD boundary with offsets 0 to 7, an address on a DWORD boundary updates that DWORD and returns its old value, and any other address stops the dispatch, which the recompiler reports as an unaligned access fault.

 - [Dual-source blending](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) takes the MRT1 export as the second source of the MRT0 blend, as RADV and radeonsi program it; what the CB does with other export or target layouts is unknown, so they throw.
 - [Blending into reversed-order color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - 8_8_8_8 and 16_16_16_16 targets with `COMP_SWAP` 2 or 3 keep the exported alpha in their first channel and red or blue in their fourth, which Vulkan would blend with the color and the alpha equation respectively. The color block is taken to blend in shader export order and apply `COMP_SWAP` afterwards: the alpha equation and every source-alpha factor use the exported alpha, and the destination alpha is the first channel. This follows the `CB_TARGET_MASK` text of the AMD [SI](https://xorg.freedesktop.org/docs/AMD/old/SI_3D_registers.pdf) (p. 229) and [CIK](https://xorg.freedesktop.org/docs/AMD/old/CIK_3D_registers_v2.pdf) (p. 238) register references ("the order of components after blending and before COMP_SWAP is applied"). RADV builds `CB_BLENDn_CONTROL` without regard to the swap ([radv_pipeline_graphics.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/amd/vulkan/radv_pipeline_graphics.c#L650-L709)) and renders R4G4B4A4, B4G4R4A4, R5G5B5A1 and B5G5R5A1 with `SWAP_STD_REV` and `SWAP_ALT_REV` ([vk_format.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/vulkan/util/vk_format.c#L43-L48), [ac_formats.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/amd/common/ac_formats.c#L609-L624)). Mesa CI's Navi10 (gfx1010) CTS run ([job 112381553](https://gitlab.freedesktop.org/mesa/mesa/-/jobs/112381553), [112381554](https://gitlab.freedesktop.org/mesa/mesa/-/jobs/112381554)) passes all 400 `blend.format.<format>.states` cases of each of those formats, including separate alpha and destination-alpha factors. It is not measured on gfx1013 or on 8_8_8_8 and 16_16_16_16 targets. Factor pairs Vulkan applies per channel are used directly. Otherwise the pixel shader only copies values: it writes the exported alpha, each channel's own export or the constants 0 and 1 into a second color at location 0 index 1 (and 1 into a channel of the first color whose source factor is ONE, moving its export into the factor), and the blend forms every factor, `1 -` and product from those copies through `SRC1_COLOR`/`SRC1_ALPHA` factors. The blend unit therefore rounds them as it rounds a plain Vulkan blend of the same export; Vulkan does not require a second-source color to be converted like the first, but on an RTX 5080 and lavapipe every reversed-order case of the execution test is bit-identical to the same draw into a `SWAP_STD` target, which the test checks. Factor combinations that copies cannot express (for example `ONE_MINUS_SRC_ALPHA` in the alpha equation with `SRC_COLOR` in the color equation), sRGB, SNORM and integer targets, constant and second-source factors, destination-alpha and `SRC_ALPHA_SATURATE` factors in the color equation, different color and alpha operations, MIN or MAX with factors other than ONE, other color exports when the blend needs the second color, and devices without `dualSrcBlend` throw. Gran Turismo 7 (PPSA01317) blends `CB_BLEND0_CONTROL` 0x65010504 into such a target (#4782).
 - [DB_SHADER_CONTROL.CONSERVATIVE_Z_EXPORT](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderInputState.cpp) (libSceAgcDriver) becomes `DepthLess`/`DepthGreater`. For a pixel shader that breaks the promise, the host driver decides whether its interpolated Z is depth-tested before shading; what the console does then was not measured.

Subject: [PATCH 0951/1000] test(agc): read the depth bits of a SW_64KB_Z_X
 surface from guest memory

A compute shader loads every texel of a 256x192 32_UINT, 32_SINT and
16_UINT texture in SW_64KB_Z_X whose memory holds a known pattern and no
depth surface, from untracked memory and from a guest allocation, and
stores what it read. Every texel must keep its stored bits, NaN, infinity
and denormal patterns included; without the 32-bit fix the 32_UINT read
throws.

Subject: [PATCH 0953/1000] perf(agc): release settle-retired imports after the
 overlap block of a pin wait

The Windows release of imports retired during a settle read belongs after the whole
overlapsImport block in the not-holding-the-lock branch of WaitForLeasesAndImports, as in
the original change, not inside it. It was placed inside while main was merged in.

 ### Unknown function info
 
 - [sce::Json::Parser::parse with a read callback](../../../core/libs/prx/libSceJson2/Export.cpp) (libSceJson2) - the callback's contract is taken from PPSA04540's: it returns 0 with the next character, and at the end of its data writes `'\0'` and returns -1. Characters are read until the callback returns non-zero or gives `'\0'`, and the text read is then parsed as by the `(text, size)` overload, so trailing characters after the value are rejected as there. Whether the console stops reading at the end of the top-level value, and what it returns when the callback fails before the end, are unknown
-- [sce::Json::Parser::parse](../../../core/libs/prx/libSceJson2/Export.cpp) (libSceJson2) - a number that overflows a double (e.g. `1e309`) throws: whether the console rejects the document or stores an infinite real is unknown
+- [sce::Json::Parser::parse](../../../core/libs/prx/libSceJson2/Export.cpp) (libSceJson2) - a null text pointer or zero size returns `JsonErrorParse` (0x80920101) without modifying the destination Value; whether the console distinguishes a null pointer from a syntax error with a separate parameter error code is unknown. A number that overflows a double (e.g. `1e309`) throws: whether the console rejects the document or stores an infinite real is unknown
 - [sce::Json::InitParameter2, InitParameterRtti and InitParameterRtti2](../../../core/libs/prx/libSceJson2/Export.cpp) (libSceJson2) - layouts inferred, not known. `InitParameter2` is taken as the 40-byte object of [SharpEmu](https://github.com/sharpemu/sharpemu/blob/1811cef94435db7655209fb39f65ddf258b93fd6/src/SharpEmu.Libs/Json/JsonExports.cs) and [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/eda6ba37ece127ab0396378404d99182e3e8a530/src/libs/libJson2.cpp): the allocator, its user data, the file buffer size, the 32-bit special float format type at 0x18 and 12 bytes both zero, and both constructors zero all of it. `InitParameterRtti2::setAllocatorRtti` writes the allocation parameters and user data where `setAllocator` writes the allocator, as both references do; whether the console also marks the object as using RTTI allocation is unknown. `InitParameterRtti`'s constructor writes the allocation parameters, user data and file buffer size to the first 24 bytes, an order inferred from its mangled arguments. The values of `SpecialFloatFormatType` and what they select are unknown, so `setSpecialFloatFormatType` stores any value and nothing reads it: `Initializer::initialize(InitParameter2)` ignores every field as `initialize(InitParameter)` does, serializing a non-finite real throws whatever the type, and whether the type lets the parser accept NaN or infinity is unknown. The setters return nothing; whether the console's return `this` is unknown
 - [sce::Json::Object::Pair and sce::Json::Array::iterator members](../../../core/libs/prx/libSceJson2/Export.cpp) (libSceJson2) imported by PPSA30601 - the signatures follow the mangled names, with `Array::iterator::operator++(int)` returning its copy through a result pointer before `this` as `Array::begin` does, since the iterator has a non-trivial destructor. `Pair(const String&, const Value&)` deep-copies both into the layout `Object` iteration already hands out (key at 0, value at 0x10) and zeroes the 8 bytes between them; what the console keeps there is unknown. The default-constructed iterator is singular
 - [sce::Json::MemAllocator::notifyError](../../../core/libs/prx/libSceJson2/Export.cpp) (libSceJson2) - the base class's virtual does nothing. A title's allocator that does not override it calls it through its own vtable; the library never calls the title's allocator, so it never reports an allocation failure. Whether the console's base implementation logs anything is unknown

+# Environment variables
+
+The code reads environment names through `getenv`, `IsEnvironmentSet`, `kibSetting` and `MaskFromEnvironment`. This table lists every `APS5_*` and `ANYPS5_*` name it reads, its kind, the value used when it is unset and what it does, one table per library. Regenerate the names with `python3 tools/env_reference.py --table`; the Conventions check fails when a name the code reads has no row here, or a row's name is no longer read.

Subject: [PATCH 0965/1000] fix(agc): keep a settled import compared while a
 storage image overlaps it

Since #6678, a Windows host import under 1 MiB returns to the write watch
once its deferred settle read has completed, and GuestMemory::Rewatch
stamps every block of it as a CPU store. The return waited only while
storage results were pending over the import. A storage image can take
its generation before the stamp and have results pending only after it:
an image's first upload takes its generation and then imports its block,
a recorded draw marks its targets pending once it is recorded, and the
settle is polled at the import lookups between the two. The image's
next refresh then takes the stamp for a CPU store over its results,
drops them and uploads the guest bytes again, so the GPU's output is
lost. On an RTX 3070 this also splits the first two draws of
agc_driver_address_passes into two passes.

A settled import that a live storage image overlaps now stays compared,
as every import under 1 MiB was before #6678. Imports with no image over
them still return to the write watch. Keeping the import compared, rather
than waiting for the image to go, checks each settled import against the
live images once instead of at every poll. The [buffers] line counts the
imports kept compared.

agc_import_settle_storage_image makes an image whose first upload imports
its block, waits for the settle read, clears the image on the GPU, then
refreshes and stores it. On the old code the refresh drops the clear.

Subject: [PATCH 0966/1000] docs(agc): say a settled import under a storage
 image stays compared

ARCHITECTURE.md and the libSceAgcDriver debt entry now say that a
settled Windows import under 1 MiB returns to the write watch only when
no storage image overlaps it, and why.

 - A draw whose `PA_SC_AA_CONFIG` selects 2, 4 or 8 samples renders into host-only multisampled images. [`MultisampleTarget.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) keeps one image per device, surface address, format, extent and sample count (`MultisampleTargetView`); the pipeline, render pass and library keys carry `State::samples`, and a multisampled depth target is a multisampled depth surface. The guest sample planes and FMASK are never read or written, so the registry also guards the target's guest range: a CPU read (`GuestMemory::SetReadGuard`), a DMA copy, and a sampled or storage image read of it throw. A `CB_COLOR_CONTROL` resolve mode over a multisampled CB0 runs as a render pass whose resolve attachment is CB1's resident image (`ResolveMultisampleTarget`). A zero fill of the target's CMASK (`NoteColorMetadataFill`, from fill kernels and CP DMA fills) clears the image at its next use.
 - A texture over a depth surface samples the depth image itself when it views one 2D slice of the plane's own format (`DepthSurfaceTexture` in [`DepthSurface.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/DepthSurface.cpp)). A view of several slices (a 2D array or a cube) or an integer view of a D16 plane is served by a `DepthPlaneCopy`, an image the slices are copied into at every use: from the depth surface bound at each slice's address, else from guest memory. Such a texture is never kept in the resource templates (`RefreshedPerUse`).
 - Guest memory reaches the GPU through host imports (`VK_EXT_external_memory_host`) where the driver accepts them, and through copies otherwise ([`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp)). A registered range larger than the import window (64 MiB) is imported per window for buffer and fill accesses and whole for an address-based build. Live imports stay under a budget, with the least recently used import retired first (see TechnicalDebt, Host import windows and budget).
-- On Windows, a host import of private `MEM_WRITE_WATCH` memory (singly mapped direct memory) stays on `GetWriteWatch` when `ProbeImportWriteProtection` shows the driver reports nothing written after the second GPU read and a GPU write, and a CPU store is collected (`decideImportWatch`). The driver marks every page of such an import written, asynchronously, until a GPU use of it completes (a read on the settle queue ends it even while main-queue work that used the import first is still running, and the first use of an earlier import of the same pages after that read marks nothing), so `settleImport` in [`GuestBufferMemory.cpp`](../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) copies 4 bytes out of the new import on a second queue of the graphics family, or on a queue of another copy-capable family when the graphics family has only one (`Context::settleQueue`, own pool and mutex) inside `ImportWatched`'s window and waits for it, for imports of 1 MiB or more; the main queue can't be used there because `importAllocation` holds the imports lock and `GpuMutex` comes before it in the lock order. A smaller import is compared when it is made, so a title that maps, imports and unmaps a small buffer around every submission does not block its mapping thread. Its 4-byte read is queued instead: the next import lookup that holds `GpuMutex` while the imports match the registry (`settleUnwatchedImports`) records the queued reads into one batch on the settle queue, and once the batch's fence has signalled a later lookup returns the import's whole 64 KiB blocks to the write watch (`GuestMemory::Rewatch` drops their marks and stamps every block as a CPU store), except while storage results are pending over them. A settled import whose range had already left the watch returns the same way, and an import retired while its read is in flight is kept with that batch and freed once the batch has completed, without waiting for it; a guest unmap of its memory waits for the batch instead. `APS5_NO_DEFERRED_SETTLES` (any value) keeps every import under 1 MiB compared. Imports through a section alias keep tracking on the guest views, and every other Windows host import is compared. A device without such a queue keeps the comparisons. On Linux the settle queue is made when the device imports dma-buf memory, and every dma-buf import of 1 MiB or more is settled right after it is made, for another reason: the kernel maps an import's pages for the GPU at the first submission that uses it, which took about 2 s for a 3 GiB import on RADV and held up the title's frame. The import's buffer is shared with the settle queue's family instead of aliased, since a sparse import is bound to many memory objects.

 - [Draw input snapshots](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver): `PrepareDrawBindings` caps read-only input buffer snapshots at 64 MiB (overridable via `APS5_DRAW_SNAPSHOT_MAX_MIB`). Larger inputs (streaming heaps, bindless pools) or draws exceeding the cumulative budget skip the per-draw snapshot and bind in place, avoiding multi-gigabyte CPU copy stalls (such as Ratchet & Clank: Rift Apart PPSA01474 stalling at frame ~380 copying 36 GB every 5 s). If the title rewrites those large ranges on the CPU before GPU completion, the in-place binding observes the modification, as verified by `drawSnapshotCapTests`.
 - [Pending storage-image results](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) are stored when something reads their memory, not when the GPU work that wrote them completes. A title that waits for that work, frees the image and reuses its memory can have the new data overwritten by the late store (#1970). A title's own CPU reads are not seen either, so a title that reads the results after waiting for a label reads stale memory. `APS5_STORE_AT_FLIP=1` stores every pending result at each flip and `APS5_STORE_AT_LABEL=1` before each label the GPU writes; both store every pending image, not only the ones the waited-for work wrote, and neither is on by default.
 - [Pending storage-image results over memory outside the write watch](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp) (libSceAgcDriver) leave to the CPU the 64 KiB blocks whose bytes differ from the ones saved at the upload, the fill, the image copy, the previous store or the moment their range left the watch (`Unwatch`, or a host import that does not stay watched), and the blocks the watch saw the CPU write before that moment. A store made on the GPU saves its bytes through a host-visible copy that becomes the saved bytes when its batch completes; a store or a refresh that needs them earlier waits for that batch. A unit without a write generation saves the guest bytes when results land in it outside the watch. One whose range leaves the watch while its results are pending, and ranges that leave the watch through a failed collect, have no saved bytes; storing such results throws.
-- Windows host-pointer imports of the guest mapping itself are compared instead of write-watched, except writable imports of private `MEM_WRITE_WATCH` memory when the import probe keeps the write watch and a settle queue exists: those of 1 MiB or more stay watched, and smaller ones return to the watch once their settle has completed (see Pages under an import window): a driver can mark imported pages dirty after the synchronous import window. Shared memory imported through a separate writable alias retains protection-based tracking on the guest views; driver access to the import alias does not disarm those views. [GuestMemory](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) excludes every overlapping 64 KiB tracker block while its backing is retained. A full block replaced by fresh private backing regains tracking and gets a new generation; protection changes, partial replacements and shared remappings do not restore it. Excluded blocks keep their write-watch marks as a hint only (`UntrackedHint`): a storage image or a sampled texture snapshot over them compares its bytes again after a mark in its range, a driver store, a mapping change or a recorded GPU write instead of at every collect epoch or lookup, and a mark the driver makes without a CPU store costs one comparison. This preserves CPU edits through byte comparisons but limits snapshot reuse on excluded blocks to draws of one collect epoch and disables unit shadows for them; restoring tracking on import retirement without replacing the backing remains unimplemented.

 - [Pages under an import window](../../../core/libs/prx/libSceAgcDriver/Execution/src/GuestMemory.cpp) (libSceAgcDriver) whose write protection was resolved while a host import that leaves its range watched was made are compared with the bytes they held before the import and count as stored over only when those differ. A CPU store of the bytes already there within the window cannot be told apart from an import that resolves the write protection without storing, as the NVIDIA driver (610.57.04) does for every imported page, so such a store does not win over pending results. Where host-pointer and dma-buf imports differ in whether they stay watched, a failed host-pointer import and the dma-buf import after it are two windows, and the pages the failed one resolved count as stored over. On Windows, the NVIDIA driver (617.42) marks every page of a host import of private `MEM_WRITE_WATCH` memory written, asynchronously, until a GPU use of the import completes; a 4-byte read of it on the settle queue ends that even while main-queue work that used the import first is still running, and an earlier import of the same pages whose first use runs after that read marks none of them (`agc_import_settle_first_use`, `agc_import_settle_earlier_import`). Such an import stays watched only after a 4-byte read of it on the settle queue has completed inside the window. Each one waits for that read, which keeps its window open for one round trip on the settle queue, so a same-value CPU store from another thread in that time counts as unchanged too. An import made where no settle queue exists is compared instead. An import of under 1 MiB is not settled inside its window, because the settle blocks the importing thread and a title that imports a 64 KiB buffer around every submission lost about 19 % of its frame rate to that wait (Dripl1x, #6060). It is compared until its read, submitted in a batch by a later import lookup under `GpuMutex` while the imports match the registry, has completed; a later lookup then returns its whole blocks to the write watch, each stamped as a CPU store, so whatever was derived from them while they were compared reads as changed once. Its blocks stay compared while storage results are pending over them, and those of an import retired before that stay compared.
 - [Settled dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a dma-buf import of 1 MiB or more is read by a 4-byte copy on the settle queue right after it is made (`settleImport`), so the kernel maps its pages for the GPU there and not in the first submission that uses it (about 2 s for a 3 GiB import on RADV). The import's buffer is shared with the settle queue's family. An import made at map time settles on the guest thread that maps the range, inside its map call, so that thread waits while the kernel maps the pages: 0.47 to 2.2 s for the 3 GiB range of Hades (PPSA03355) and 0.49 to 4.3 s for the 4.5 GiB range of ASTRO BOT (PPSA21567) on RADV. Both titles map these ranges at start-up; a title that maps large ranges during gameplay stalls its mapping thread for as long. An import made from a submission settles under the GPU mutex, so its frame still pays for it; a smaller import, and every import on a device with no settle queue (one without a copy-capable queue besides the main one), pays in its first submission. A range imported through a host pointer, as lavapipe imports shared memory, is not settled
 - [Sparse dma-buf imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): on Linux a shared-backed range larger than one 64 MiB udmabuf buffer is imported as one sparse buffer bound to the 64 MiB buffers, on a queue of its own when the device has a second family that binds sparse memory. The path is decided before anything is imported, and a failure after that throws. A range takes the single udmabuf import instead, which udmabuf's `size_limit_mb` refuses above 64 MiB by default so the range is copied, when its offset in the backing file is not a multiple of the buffer's sparse block size (64 KiB on RADV), when the sparse buffer does not accept every memory type a chunk import can have, when the backing file ends inside its last chunk, or when it is imported at map time on a device with no second family (the bind then needs the GPU mutex); the NVIDIA proprietary driver imports no dma-buf memory

Subject: [PATCH 0968/1000] docs(agc): bound the released-texture sweep by the

 - [Flip packets raise the graphics end-of-pipe event](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Packets/PacketExecution.cpp) (libSceAgcDriver) - a flip delivers the queue's end-of-pipe event (`sceAgcDriverAddEqEvent`) once the work recorded before it completes, as a `RELEASE_MEM` with `INT_SEL` does. Minecraft (PPSA17221) registers the graphics event, never requests an interrupt in its releases, and waits on the event after every flip while holding its render lock, so without this it never presents a second frame. Whether the console raises the event from the flip itself or from an interrupt its flip sequence contains is not measured; a title that waits only on release interrupts sees one extra event per flip, with `data` counting it.
 - [Host import windows and budget](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): a registered range larger than 64 MiB is imported one 64 MiB window at a time for buffer and fill accesses; an access across window edges imports the cells it touches, grown to the union of the range's imports it overlaps. An address-based build (`AcquireRegistered`) imports the range whole and replaces its windows. Live imports stay under a budget: `APS5_HOST_IMPORT_MIB`, else the larger of 6 GiB and half the physical memory, at most the largest host heap less 2 GiB (imports and type-3 mirrors share it; #167's rule). A new import beyond it retires the least recently used imports not used in the last 256 lookups; one that would not fit even then is refused before anything is retired, and imports made when a range is mapped never evict. A refused import is tried again at its next use. The 64 MiB window, the 256-lookup protection and the 2 GiB reserve are choices, not measured.
 - [Registration preparation at submit](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Queues/Submission.cpp) (libSceAgcDriver) - `Driver::Submit` waits for every registration-time shader preparation queued before the call, not only those of the shaders the commands use, so a submission behind a long queue of unrelated preparations waits for all of them on the submitting thread. Waiting there instead of in the queue worker keeps the GPU side of a submission short: a title that sees a submission take seconds treats the GPU as hung (Goat Simulator 3, PPSA04159, then stops submitting and its garbage collector fails a 10 s timeout). On the console shaders are compiled ahead of time, so neither wait exists; how long a title tolerates a slow submit call is not known.
-- [Resource cache entries holding released textures](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - a sampled texture the texture cache drops while something else holds it, or makes without caching (`admitTexture` refusing a first use), is marked released, and `ResourceCache::Insert` refuses descriptor sets that hold one and removes the entries that do. The removal waits for the next insert: until then `Find` still returns those entries and their textures stay alive. One process-wide flag starts the sweep, so while the sampled cache is over its budget every insert scans all entries (up to 1,024, each with its textures); that cost is not measured. A draw or dispatch whose textures the cache refused builds its descriptor sets again on each use for as long as the cache stays full; the count bounds (`APS5_RESOURCE_CACHE_ENTRIES`, `APS5_RESOURCE_CACHE_TABLE_ELEMENTS`) still bound nothing by bytes, and sampled textures made outside the texture cache (the disabled cache, depth-surface copies) are never marked. Measured only on Ghost of Yōtei (PPSA26344) on one RTX 4090: with the default bounds, sampled textures held outside the cache peaked at 2,836 MiB (7,830 MiB before) and device-local heap 0 stayed under its 22.9 GB budget for the whole run (26,357 MiB before, which aborted with `VK_ERROR_OUT_OF_DEVICE_MEMORY` at the wolf scene). Whether the extra descriptor-set builds cost frame time elsewhere is not measured.

When `ReleaseTextureCaches` runs on device memory exhaustion, the sampled textures these entries hold are only marked released and are freed at the next insert, so the immediate allocation retry gets no memory back from them. A draw or dispatch whose textures the cache refused builds its descriptor sets again on each use for as long as the cache stays full; the count bounds (`APS5_RESOURCE_CACHE_ENTRIES`, `APS5_RESOURCE_CACHE_TABLE_ELEMENTS`) still bound nothing by bytes, and sampled textures made outside the texture cache (the disabled cache, depth-surface copies) are never marked.

Whether the extra descriptor-set builds cost frame time elsewhere is not measured.
 - [Unclamped normalized color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - CB_COLOR_INFO targets with BLEND_CLAMP clear (bit 15) on UNORM and SNORM formats are accepted when blending is disabled (ENABLE clear or BLEND_BYPASS set). Vulkan converts unblended shader values and clamps to the normalized range automatically; blending into an unclamped normalized target remains unmodeled because Vulkan always clamps inputs prior to blending.
 
 - [Thick SW_4KB_S_X volumes](../../../core/libs/prx/libSceAgcDriver/Graphics/src/TextureTiling.cpp) use AMD addrlib's GFX10 non-RB+ 16-pipe `GFX10_SW_4K_S3_X_PATINFO` equations for 1, 2, 4, 8 and 16-byte elements, including packed mip tails. The layout follows [AMD PAL c5e80007](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp); it has not been measured on console hardware. Other thick swizzle modes outside the supported families still throw. Mipmapped 3D color targets remain refused by the color-register decoder.

Subject: [PATCH 0972/1000] fix(libkernel): reject Windows volume mount points
 in junction reads

A mounted folder uses the junction reparse tag and would otherwise be returned as a relative Volume GUID path. Only a drive path is reported, through the absolute-link text helpers.

 - [Windows file timestamps](../../../core/libs/prx/libkernel/File/include/WindowsFileTime.hpp) use the host filesystem's timestamp range and resolution. `utimes`, `futimes`, and `lutimes` reject timestamps outside nonnegative signed 64-bit Windows file-time ticks with `EINVAL`, including exactly 1601-01-01 00:00:00 UTC, whose zero value means "leave unchanged" to `SetFileTime`. Guest directory descriptors still resolve through their recorded path. Filesystems with coarser timestamp resolution cannot retain every guest microsecond
 - [EVFILT_VNODE on macOS](../../../core/libs/prx/libkernel/Equeue/src/FileEvent.cpp) (libkernel) registers `EVFILT_VNODE` on a duplicate of the descriptor in a host kqueue, whose notes have FreeBSD's values, and drops the `NOTE_LINK` that XNU adds to `NOTE_DELETE` when the watched file or directory is removed, since FreeBSD's `vop_remove_post` and `vop_rmdir_post` report `NOTE_DELETE` alone. As on Windows, a directory registered with `NOTE_EXTEND` is accepted but never receives it: XNU reports a move between directories as `NOTE_WRITE` alone, with `NOTE_LINK` for a subdirectory
 - [Windows file identity](../../../core/libs/prx/libkernel/File/src/NativeStat.cpp) (libkernel) - `stat` and `fstat` report the volume serial number as `st_dev` and the 64-bit file index folded into the guest's 32-bit `st_ino` (never 0), so two different files can in principle share an `st_ino`; the fold is not taken from a reference. `st_nlink` is clamped to 65535, the width of the guest field. The call keeps the `_wstat64` values when `GetFileInformationByHandle` fails
-- [lstat of a Windows symbolic link](../../../core/libs/prx/libkernel/File/src/NativeStat.cpp) (libkernel) reports a link whose target is relative, as `symlink` creates them, with the link's own times, `st_dev` and `st_ino`, mode `S_IFLNK | 0777` and the length of the target `readlink` returns as `st_size`. FreeBSD gives a new link `0777` less the creating process's umask, which the host does not keep, so the permission bits are not the console's. A directory junction is reported the same way, using its print name, or its substitute name when the print name is empty, without a `\??\` or `\\?\` prefix. A link with an absolute target and any other reparse point throw, as for `readlink`

A link with an absolute target is reported the same way, using its print name, or its substitute name when the print name is empty, without a `\??\` or `\\?\` prefix. A directory junction is reported the same way when the name left after that prefix is a drive path (`X:\...`): the print name when that name is a drive path, otherwise the substitute name. A mounted volume, whose substitute name is `\??\Volume{GUID}\`, and any other reparse point throw, as for `readlink`
 - [setitimer](../../../core/libs/prx/libkernel/System/src/Signals.cpp) (libkernel) follows FreeBSD's `sys_setitimer` and `kern_setitimer`: `EINVAL` for timers other than `ITIMER_REAL`, `ITIMER_VIRTUAL` and `ITIMER_PROF`, and for a value, or the interval of a non-zero value, with a negative field, `tv_usec` of 1000000 or more, or more than `INT32_MAX / 2` seconds; a null value reads the timer as `getitimer` does, with `EFAULT` when the output is null too. `ITIMER_REAL` shares the timer thread of `alarm`, which clears its interval: a zero value disarms it, the previous value is returned, and each expiry re-arms it by `it_interval`. An expiry delivers nothing: with `SIG_IGN` it is dropped, with the default disposition the process exits with status 142, and with a handler, or with `SIGALRM` blocked, it throws, since guest `SIGALRM` handlers are never run and signals are never left pending. The value is not raised to `tick / 16` as `itimerfix` does, and an interval below 1 ms throws, since the console's `hz`, and so that rounding, is unknown (1 ms covers any `hz` of 63 or more). `ITIMER_VIRTUAL` and `ITIMER_PROF` throw when armed, as process CPU time is not accounted, and read and disarm as zero. PPSA99420 imports it and fails to load without it
 - On Linux, [direct memory](../../../core/libs/prx/libkernel/DirectMemory/DirectMemory.cpp) lives in one sparse memfd at file offset = physical address, so the [GPU imports](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) can share one udmabuf buffer object per 64 MiB of it. Released direct memory is not punched out of the file, because a live import of its chunk pins the pages and the GPU would keep reading the old ones: its pages stay committed (the process keeps the high-water mark of the direct memory it used) and are zeroed when the range is allocated again.
 - [system](../../../core/libs/prx/libkernel/System/src/Process.cpp) (libkernel) runs no command. It follows FreeBSD 11's `lib/libc/stdlib/system.c` for a sandbox without `/bin/sh`: a null command returns 1 unconditionally, as that version does, and any command returns the wait status of a child that could not exec the shell and called `_exit(127)` (`0x7f00`). Whether the console's application sandbox has no shell, and whether `vfork` succeeds there (FreeBSD returns -1 when it fails), is unverified

 - [fchmodat](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) passes `AT_FDCWD` (-100) and absolute paths to `chmod`; any other relative path is joined to the descriptor's host directory the same way as for `openat`, so guest path aliases and case-insensitive name matching do not apply to it and a `..` component is not kept inside the guest root. A flag other than `0` or `AT_SYMLINK_NOFOLLOW` (0x200) returns `EINVAL`; the mode is masked to `07777`. With `AT_SYMLINK_NOFOLLOW` a symbolic link returns success silently on Windows and Linux, since the host cannot change a link's own mode, while a regular file is changed either way. The mode maps to the host file mode, which on Windows is only the CRT's read-only bit. PPSA99621 calls it through `std::filesystem::permissions`. Console behaviour is unverified
 - [pathconf](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) looks the path up as FreeBSD 11's `kern_pathconf` does (links followed, `ENAMETOOLONG` for a path of 1024 bytes or more or a component over 255) and returns the constants of FreeBSD 11's UFS `ufs_pathconf` for files and directories alike: `_PC_LINK_MAX` 32767, `_PC_NAME_MAX` 255, `_PC_PATH_MAX` and `_PC_SYMLINK_MAX` 1024, `_PC_PIPE_BUF` 512, `_PC_CHOWN_RESTRICTED` and `_PC_NO_TRUNC` 1, `_PC_FILESIZEBITS` 64, `_PC_REC_MAX_XFER_SIZE` -1, `_PC_PRIO_IO` and `_PC_SYNC_IO` 0. Whether the console's filesystems report the same is not verified. It throws for the names whose UFS value depends on the mount (`_PC_ALLOC_SIZE_MIN`, `_PC_REC_INCR_XFER_SIZE`, `_PC_REC_MIN_XFER_SIZE`, `_PC_MIN_HOLE_SIZE`), the kernel options (`_PC_ACL_EXTENDED`, `_PC_ACL_PATH_MAX`, `_PC_ACL_NFS4`, `_PC_MAC_PRESENT`) or the page size (`_PC_REC_XFER_ALIGN`), and on which UFS and `vop_stdpathconf` disagree (`_PC_MAX_CANON`, `_PC_MAX_INPUT`, `_PC_VDISABLE`, `_PC_ASYNC_IO`); other names fail with `EINVAL`

Any other relative path is joined to the descriptor's host directory, found the same way as for `fchdir`, so guest path aliases and case-insensitive name matching do not apply to it, and a `..` component is not kept inside the guest root. It returns `EBADF` for a descriptor that is not open and `ENOTDIR` for one that is not a directory. On Windows, `mode` is ignored. Console behaviour is unverified
-- [readlink](../../../core/libs/prx/libkernel_sys/Export.cpp) (libkernel_sys) on Windows reads a symbolic link's target from its reparse data and returns it with `/` separators, only when the target is relative, as `symlink` creates them.

A symbolic link with an absolute target returns its print name, or its substitute name when the print name is empty, without a `\??\` or `\\?\` prefix. A directory junction returns the same kind of name when it is a drive path (`X:\...`), using the print name when that is a drive path and the substitute name otherwise.

Subject: [PATCH 0973/1000] fix(shader): keep clip distances in the blocks
 between the barycentric tessellation stages

#7330 passes the vertex clip distances as separate ClipDistance arrays so
the control stage's input matches the vertex shader's output. SPIRV-Cross,
which MoltenVK uses, cannot translate a separate ClipDistance array in a
tessellation evaluation stage, so on MoltenVK every pipeline of the
barycentric tessellation route failed to compile. The control stage now
reads the separate array the vertex shader writes and passes it on inside
its per-vertex block, which the evaluation stage reads and writes.

 - [Mesh shader grid size](../../../core/shader/recompiler/SpirvBackend/src/SpirvModuleEmitter.cpp) (shader recompiler) - every mesh shader loads `NumWorkgroups.x` and declares no vertices when it is 0, which no dispatch produces. The read is a workaround for RADV (Mesa 26.2.4, seen on an RX 9070 XT, GFX12): binding a mesh pipeline whose shader reads neither `NumWorkgroups` nor `DrawIndex` keeps the user SGPR count and draw-id flag of the vertex pipeline bound before it in the same command buffer (`radv_bind_pre_rast_shader` updates them only when the shader has the `AC_UD_VS_BASE_VERTEX_START_INSTANCE` slot), so `radv_emit_userdata_mesh` opens a 3-register `SET_SH_REG` and writes one value, the CP takes the following `DISPATCH_MESH_DIRECT` as register data and the GPU hangs (gfx ring timeout, MODE1 reset). Kena: Bridge of Spirits (PPSA01802) hits it on its layered volume draws. Reading `NumWorkgroups` gives every mesh shader the grid-size slot, so the count and the values match; drop the read once a fixed Mesa is the minimum
 - [Shader recompilation](../../../core/shader/recompiler/Recompiler.cpp) currently occurs right before it was transferred to Vulkan with caching, but should be moved to the [relinker](../../../core/relinker/main.cpp) stage. For this purpose, [shader/recompiler](../../../core/shader/recompiler) was written completely independently from [libs/prx](../../../core/libs/prx).
 - [v_interp_p1ll_f16, v_interp_p1lv_f16 and v_interp_p2_f16](../../../core/shader/recompiler/Translation/src/AttributeInstructions.cpp) read the 16-bit halves of each vertex's parameter through `VK_KHR_fragment_shader_barycentric`, as fixed-function interpolation cannot split a 32-bit attribute. Without the extension the pixel shader takes the [barycentric emulation](../../../core/shader/recompiler/SpirvBackend/src/BarycentricGeometryShader.cpp), whose generated geometry stage passes each vertex's parameter to it as a flat input, so the halves arrive bit for bit; a device without geometry shaders takes the tessellation stages of the same emulation instead, which no 16-bit interpolation test has run through yet. P10 and P20 are the vertex differences rounded to f16 to nearest even, which is not confirmed on hardware. v_interp_p1ll_f16 and v_interp_p1lv_f16 round the exact `P10 * I + P0` once to f32 and v_interp_p2_f16 rounds the exact `P20 * J + S2` once to f16, as measured on RDNA2 (#697); the exact sums are computed in f64, so these instructions need the Float64 capability. They follow the shader's float mode, measured on RDNA2 (gfx1035) in all eight combinations of `IEEE_MODE` and kept/flushed f32 and f16 denormals over 768 special and 1,024 random rows. With IEEE=1 a NaN operand is returned quieted; with IEEE=0 it is returned unquieted, except that v_interp_p2_f16's f16 result is always quiet. Flushed f32 denormals flush I/J, v_interp_p2_f16's f32 S2 and the f32 result; flushed f16 denormals flush P0, P10/P20, v_interp_p1lv_f16's f16 S2 and the f16 result. Denormal modes 1 and 2 (flush only inputs or only outputs) and rounding other than to nearest even are not measured and throw. An unknown mode follows IEEE=0 with denormals kept. Lavapipe has no barycentrics, so the draw test is skipped in CI; `agc_driver_interpolation_modes` checks the arithmetic in every mode against the hardware rows on any device with Float64.
-- Without `VK_KHR_fragment_shader_barycentric`, a pixel shader whose I/J VGPRs [only feed `v_interp_p1_f32`/`v_interp_p2_f32` of their own pair](../../../core/shader/recompiler/Optimization/src/HostInterpolationChecker.cpp) reads the attribute Vulkan interpolated. Any other read of them or of a raw vertex parameter takes the weights and the three vertex values from a [generated geometry stage](../../../core/shader/recompiler/SpirvBackend/src/BarycentricGeometryShader.cpp), which needs `geometryShader` and a vertex shader before it. On a device with `tessellationShader` but no `geometryShader` (MoltenVK), a triangle list without primitive restart takes them from [generated tessellation stages](../../../core/shader/recompiler/SpirvBackend/src/BarycentricGeometryShader.cpp) instead: each triangle is one three-point patch at tessellation level 1, the evaluation stage writes the corner `gl_TessCoord` points at as the weights, and the vertex clip distances are forwarded. A flat parameter takes the first vertex's value there, as the geometry stage's strip gives it; the last provoking vertex throws. The patch keeps the triangle's facing with `VertexOrderCw`, checked with face culling on MoltenVK 1.4.2 (Apple M2) only. Tessellation, mesh and rect-list pipelines, primitives other than triangles, triangle strips and fans without `geometryShader`, more than 32 fragment input locations and interfaces beyond the device's geometry or tessellation limits throw.

 - [v_fma_f64 and v_div_fmas_f64](../../../core/shader/recompiler/SpirvBackend/src/SpirvAlu/SpirvAluEmitterFloat64.cpp) with a subnormal operand or result round once, as IEEE 754 fusedMultiplyAdd does with f64 denormals kept, measured on RDNA2 (gfx1035) at IEEE=0 and IEEE=1, `v_div_fmas_f64` with VCC clear and set. The f16/f64 denormal field of `FLOAT_MODE` (bits 7:6) is not read: when it flushes, the hardware flushes the operands and the result of `v_fma_f64` (tininess before rounding) and only the result of `v_div_fmas_f64`, while these keep them. Shaders with f64 instructions declare `DenormPreserve` for 64-bit floats only when `shaderDenormPreserveFloat64` is true and Vulkan reports `denormBehaviorIndependence` as `ALL`; other independence modes are not handled by the current backend because they require coupled execution modes. See [VkShaderFloatControlsIndependence](https://docs.vulkan.org/refpages/latest/refpages/source/VkShaderFloatControlsIndependence.html). Elsewhere (including lavapipe), the driver may flush f64 subnormals, and `agc_driver_f64_fma_subnormals` is skipped.
 - [SINT storage images](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) of 8- and 16-bit components saturate each stored 32-bit value to the component range, as adriadam10 measured for image stores on RDNA2 (gfx1035) in #944 (448 rows match); the PS5's gfx1013 is not measured. A D16 store sign-extends each 16-bit half before that saturation, as measured on RDNA2 (gfx1035) for `image_store d16` to all eight SINT formats with DMASK 0xf, 0x7, 0x5, 0x3, 0x2, 0xa and 0x1 (1792 rows match).
 - [`StoreTexel`](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) writes channel 1 of a two-channel format from the data slot whose DST_SEL is Y, for SINT and UINT alike. With DST_SEL X,Y,Z,W, gfx1035 writes it from the W slot, as adriadam10 measured in #944.

Only that pair was measured. Every 32-bit LDS atomic of a program that contains a 64-bit LDS atomic therefore takes the same lock, including a 32-bit `flat_atomic_*` whose address lands in the LDS aperture (a 64-bit one takes it already); the flat forms were not measured against a 64-bit atomic either (the other 32-bit LDS atomics, `ds_min/max`, `ds_cmpst`, the float forms, `ds_inc/dec`, `ds_mskor` and `ds_wrxchg`, are extrapolated from `ds_add_u32` and were not measured against a 64-bit atomic); a program without a 64-bit LDS atomic keeps its native 32-bit atomics. `ds_condxchg32_rtn_b64` is two `ds_mskor` halves, each under the lock but not atomic as a pair, so a 64-bit atomic between the two halves is not excluded. Sub-dword writes (`ds_write_b8`, `ds_write_b16` and their `_d16_hi` forms) and plain `ds_read_*`, `ds_write_*`, `ds_append_u32` and `ds_consume_u32` are not taken under the lock, so a plain access racing a 64-bit atomic on the same dwords can see or overwrite one half of it; whether the hardware orders them was not measured.

The lock is not used there because AMD's Windows driver compiles an acquire or release on a storage buffer, at workgroup scope or wider, to `s_barrier`, and those barriers inside the lock's divergent loop pair with the program's own `s_barrier`s. The fence after each LDS atomic compiles to `s_barrier` on that driver as well, so a wave that skips an LDS atomic that other waves of its workgroup execute misses a barrier they reach; its effect was not measured.

The returned value is always the old value as it was in memory. `IEEE_MODE` has no effect. The same bit rule serves the buffer float atomics (`AtomicFloatBits`). Not measured: a denormal or signalling-NaN `data1` of `cmpst` (stored as given). `ds_add_f32` and `ds_add_rtn_f32` follow RDNA1 (gfx1010, RX 5700 XT), measured with the [hardware oracle](../HW_ORACLE.md) template run through the Windows driver's comgr and HIP runtime over 1574 operand pairs (signed zeros, denormals, the smallest normals, infinities, quiet and signalling NaNs with payloads, the largest normals, random pairs near the denormal range and pairs that nearly cancel) in all 16 combinations of the f32 denormal field and the f32 round mode, and at IEEE 1 and DX10 clamp 0: both operands are flushed to a signed zero when bit 0 of the field is clear and the result when bit 1 is clear, the sum is rounded to nearest even whatever the round mode, a NaN data operand is stored quieted, else a NaN old value is stored quieted, `+inf + -inf` stores 0xffc00000, and `IEEE_MODE` and `DX10_CLAMP` have no effect. The sum is the host's `OpFAdd` between those flushes, so where the field keeps f32 denormals the result also depends on the host preserving them, which the module does not request. thuanquang measured the same rule on RDNA2 (gfx1031, RX 6700 XT) in #5492, with the same operand classes and 18 modes in wave32 and wave64; the PS5's gfx1013 is not measured.
 - [LDS in pixel, vertex-path and fetch programs](../../../core/shader/recompiler/SpirvBackend/src/SpirvAnalysis.cpp) (shader recompiler) - is an array private to each host invocation, in `Function` storage, as only compute and mesh programs get workgroup memory; on the console one LDS region is shared by the wave (RDNA 2 ISA sections 3.6.6 and 10.4), so a lane does not see another lane's LDS writes. Sub-dword writes (`ds_write_b8`, `ds_write_b16` and their `_d16_hi` forms), the 32-bit LDS atomics, `ds_append` and `ds_consume` load, update and store the invocation's own dword without an atomic, as Vulkan allows atomics only on `Uniform`, `Workgroup`, `Image`, `StorageBuffer`, `PhysicalStorageBuffer` and `TaskPayloadWorkgroupEXT` pointers (VUID-StandaloneSpirv-None-04686). `ds_append` and `ds_consume` update only the first active lane's copy and return its old value to every lane, so a second append after the first active lane changes, or a read of the counter by another lane, differs from the hardware. Not measured on hardware.
 - [V# bases off a DWORD boundary](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - raw accesses use the exact bytes and `s_buffer_load` reads `(base & ~3) + (offset & ~3)`, as measured on gfx1035 (Linux, alignment mode UNALIGNED; the console's mode is unknown). Formatted accesses off their element's alignment throw. Atomics use the byte address `base + offset`, base's low two bits included: measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) with `buffer_atomic_add`, `buffer_atomic_swap` and `buffer_atomic_cmpswap` and bases 0 to 3 bytes past a DWORD boundary with offsets 0 to 7, an address on a DWORD boundary updates that DWORD and returns its old value, and any other address stops the dispatch, which the recompiler reports as an unaligned access fault.

 - [Texture cache budgets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - the storage image cache's budget is what the reported heap budget leaves after the heap's use other than the cached storage images, the unused part of the sampled textures' 2 GiB floor and an eighth of the budget, capped at a quarter of the budget and at `TextureCacheBudget` (a quarter of the heap's size, at least 2 GiB), never below 512 MiB; the sampled cache's budget reserves `TextureCacheBudget` for the storage cache. So the sampled budget falls first while the sampled textures alive stay within their floor, and both fall together above it; each cache trims only at its next insert, a storage image is allocated before its insert reads the budget, and both budgets read the heap at most once a second, so a burst between two reads can still exceed the reported budget. The 2 GiB floor and the eighth are the sampled formula's values reused and the 512 MiB floor and the caps the earlier ones; none was measured beyond one title (PPSA11386) on one 10 GB GPU, and a title whose storage working set exceeds the shrunk budget re-creates storage images at each use.
+- [Polygon primitive type](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - `VGT_PRIMITIVE_TYPE` 21 (`PrimitiveType::Polygon`) decodes to `VK_PRIMITIVE_TOPOLOGY_TRIANGLE_FAN` and is treated as inactive for vertex point size, like triangle fans and strips. PPSA01317 (Gran Turismo 7) submits polygon draws; whether the console performs polygon-mode decomposition or custom vertex routing is unverified.
 - [Native multisampled DCC fast clears](../../../core/libs/prx/libSceAgcDriver/Graphics/src/MultisampleTarget.cpp) import uniform 0000/0001/1110/1111 keys into a single-layer, level-zero SW_64KB_R_X color image with 2, 4 or 8 fragments. Color and DCC/CMASK ranges must stay write-watched and unchanged; expanded or mixed initial DCC, register CMASK clears, compressed payloads, color transforms, lossy modes, metadata changes, guest publication and writes over a live owner throw. Driver-mediated reads of the color and metadata stay guarded. The metadata extent follows [AMD Addrlib](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp#L347-L454) with the [PS5 Mesa model](https://github.com/mihawk-99/PS5_Mesa/blob/0b2d6d1a61d9bbf89cf8beb88a696144f67c61f8/src/amd/vulkan/winsys/ps5/radv_ps5_winsys.c): GFX10.1, 16 pipes, 256-byte interleave, two maximum compressed fragments. Console geometry, concurrent guest mutation and transitions outside this subset are unverified.
 
 - [Initial stencil state](../../../core/libs/prx/libSceAgcDriver/Execution/include/QueueState.hpp) uses zero for `DB_STENCIL_CONTROL`, `DB_STENCILREFMASK` and `DB_STENCILREFMASK_BF` (context `0x10b`-`0x10d`), including after `CLEAR_STATE`. The public V0, V4, V5 and V7-V11 [register-default tables](../../../core/libs/prx/libSceAgc/Command/include/RegisterDefaultsData.hpp) supply these values. Linux's [GFX10 clear-state table](https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/amd/amdgpu/clearstate_gfx10.h) agrees on the control register but uses `0x01000000` for the reference masks; the console reset values have not been measured. Planet Coaster (PPSA01736 v01.017) enables stencil tests without writing the control register.

 - [NGG vertex programs on the mesh path](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - an unregistered vertex program with `PRIMGEN_EN` that uses LDS or `s_barrier` runs on the geometry (mesh) path. Each input primitive is assumed to yield at most one output primitive, the subgroup is bounded by `GE_MAX_OUTPUT_PER_SUBGROUP` as a vertex budget, and the GS/ES VGPR count checks are skipped, because the merged inputs keep their positions. Taken from the code Mesa's ACO emits for NGG culling and from PPSA59322 and PPSA99010 draws, not measured on hardware. Registered programs keep the vertex path
 - [VGT_SHADER_STAGES_EN 0x02002008](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - this one value, `ES_EN` = 1 without `HS_EN` on a non-patch draw, is drawn as the vertex path. AMD's CIK register reference calls `ES_EN` = 1 `ES_STAGE_DS` (the ES stage runs the tessellation evaluation shader), which does not explain it on a non-patch draw. Seen only on PPSA29413 and not verified on the console; other vertex-path values with `ES_EN` set still throw.
 - [Strided buffer overhang](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - a strided buffer descriptor that ends less than one stride past the end of the readable registered allocation holding its base is bound only up to that allocation's end, even when another readable allocation starts right there. This assumes the bytes past the end are the rounded-up `num_records` of the last record (RADV rounds it up), which no fetch inside the buffer reads; a guest that really keeps a vertex split across two adjacent allocations would read zeros for the cut tail. Taken from the RetroArch Dolphin core case in #2912, not measured on hardware.
+- [Buffer descriptor CACHE_SWIZZLE hint](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - bit 30 of word 1 in a buffer resource descriptor (`words[1] & 0x40000000u`) is normalized to zero when binding guest buffers in `ShaderResources::addGuestBuffer`. On GFX10 (gfx1013), bit 30 of V# word 1 is `CACHE_SWIZZLE` (Mesa's `gfx10-rsrc.json`: STRIDE [29:16], CACHE_SWIZZLE [30], SWIZZLE_ENABLE [31]), a cache-bank hint with no effect on the address or data, which is dropped here.
 - [Buffer descriptors past the range limit](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - a buffer V# whose size is over `maxStorageBufferRange` is bound only up to the end of the readable registered allocation holding its base when that allocation ends before the limit, and as the empty placeholder buffer, like a null V#, when no registered allocation holds its base; a V# over an allocation that reaches the limit still throws. Titles leave such words in descriptor slots their shaders do not reach on the path taken (PPSA10528 binds `c8010002 2c6bec20 c0053c00 04000013`, about 33 TB from an address above the user address space). What the console returns for an access past the bound range is not known; here the device's robust buffer access decides. Follows the review of #3202, not measured on hardware.
 - [Zero-stride vertex fetch range](../../../core/libs/prx/libSceAgcDriver/Graphics/include/VertexInput.hpp) (libSceAgcDriver) - for a stride-0 V# with OOB_SELECT 2 the whole fetch reads memory unless NUM_RECORDS is 0; with OOB_SELECT 3 it reads zero when NUM_RECORDS is 0 and throws when the fetch only partly fits. Rules taken from the GFX10 OOB_SELECT table in Mesa [ac_descriptors.c](https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/amd/common/ac_descriptors.c), not measured on hardware. Whether OOB_SELECT 3 checks each dword of a multi-dword fetch separately is unknown. OOB_SELECT 0 and 1 keep the structured record checks.
 - [Resource registration](../../../core/libs/prx/libSceAgcDriver/Resource/src/Registration.cpp) (libSceAgcDriver) - registration always fails with `RESOURCE_REGISTRATION_UNAVAILABLE`, so the owner and resource queries, `sceAgcDriverSetResourceUserData`, `sceAgcDriverFindResourcesPublic` and `sceAgcDriverUnregisterAllResourcesForOwner` return the same error without reading their arguments. Their parameter lists follow the libSceGnmDriver counterparts and are unverified. `sceAgcDriverGetResourceRegistrationMaxNameLength` writes 0xfc and returns 0, as [prosper](https://github.com/mattias800/prosper) does from a title's registration configuration; the `uint32_t*` parameter matches the SDK wrapper `sce::Agc::ResourceRegistration::getMaxNameLength(unsigned int*)`. sharpemu writes 256 and KytyPS5 returns `RESOURCE_REGISTRATION_UNAVAILABLE`, so the value is unverified; a null output throws

Subject: [PATCH 0981/1000] feat(agc): sample 8 and 8_8 sRGB textures through
 an RGBA8 sRGB copy

A device that cannot sample R8_SRGB or R8G8_SRGB had its sRGB textures
decoded in the shader, which cannot serve filtered samples: the decode must
come before the filter. The texture is now an RGBA8 UNORM image viewed as
RGBA8 sRGB, filled by a one-to-one blit of the R8 or RG8 texels (a snapshot's
upload, or a storage image's texels refreshed when its Version changes), so
the sampler decodes and then filters, and every sample, gather and load of
these images is an ordinary sRGB one. The recompiler is given the decode mask
only for formats the device cannot blit, or when APS5_SRGB_SHADER_DECODE=1
forces the shader decode. Tests run on lavapipe only.

 - [Unnormalized S# coordinates](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) - `FORCE_UNNORMALIZED` uses a Vulkan `unnormalizedCoordinates` sampler, so the S# LOD range, LOD bias and mip filter are not applied, which is exact only on a one-level view.
 - An [unnormalized S#](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestSamplerResource.cpp) (libSceAgcDriver) maps clamp mode 0 (repeat) on X and Y to clamp-to-edge as required by Vulkan unnormalized coordinates, and assigns the magnification filter when minification and magnification filters differ (since unnormalized coordinates sample at LOD 0). Anisotropy, TRUNC_COORD, MC_COORD_TRUNC and other clamp modes still throw. Secondary LOD bias (LOD_BIAS_SEC, bits [19:14]) is accepted and ignored, matching RDNA2 hardware measurements across explicit and implicit samples. High on Life (PPSA15388, #4736) uses secondary LOD bias and unnormalized coordinates with clamp mode 0 and differing min/mag filters during home base and city rendering.
 - [Background link-time-optimized relink of library pipelines](../../../core/libs/prx/libSceAgcDriver/Execution/include/PipelineLinkOptimization.hpp) (libSceAgcDriver) is skipped on every GPU under NVIDIA's proprietary Vulkan driver (`VK_DRIVER_ID_NVIDIA_PROPRIETARY`), so those pipelines keep their fast-linked form. The optimized link loses the device when bound on an RTX 3080 (Ampere, #2866) and an RTX 4060 (Ada, #3434); an RTX 5060 and an RTX 5080 (Blackwell) on the same driver do not, so the scope is wider than the evidence. No standard Vulkan query tells the architecture apart, and the driver version that fixes it is unknown. `APS5_NO_PIPELINE_LTO` disables the relink on every driver.
-- [8_SRGB and 8_8_SRGB textures](../../../core/libs/prx/libSceAgcDriver/Graphics/src/TextureFormat.cpp) (libSceAgcDriver) that the device samples as R8_SRGB or R8G8_SRGB use its own decode, which need not match gfx1035: NVIDIA's R8_SRGB is one bf16 step off in 29 of 256 codes.
+- [8_SRGB and 8_8_SRGB textures](../../../core/libs/prx/libSceAgcDriver/Graphics/src/TextureFormat.cpp) (libSceAgcDriver) that the device samples as R8_SRGB or R8G8_SRGB use its own decode, which need not match gfx1035: NVIDIA's R8_SRGB is one bf16 step off in 29 of 256 codes. A device that cannot sample them gets an RGBA8 sRGB copy instead (a blit of the R8 or RG8 texels, refreshed with the storage image's version), whose decode is likewise the device's; 3D textures and storage images that are not single-depth and format-matched are copied from their snapshot instead.
 - [PM4 submission rings](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Queues/SubmissionRing.cpp) (libSceAgcDriver) keep only the first 512 dwords of each submission, so the packets past them are not printed. The [failure report](../../../core/libs/prx/libc/src/FailureReport.cpp) dump does not allocate from the C runtime heap: packet names come from static strings, each line is formatted with integer and string conversions into a 512-byte stack buffer and written with one `WriteFile`. It still runs on whatever state the crash left. It waits about 100 yields for each ring's lock and otherwise prints that queue as busy, so a crash while recording a submission loses that queue's ring. It reads the rings without checking them, so a crash that corrupted them can fault inside the dump; such a fault during the report of an unhandled exception stops in that report's `Sleep(INFINITE)` and the process hangs instead of ending. The reports run at most once per process. Linux has no crash report: there the rings are printed only by `APS5_STALL_WATCHDOG_SECS`.
 - [WAIT_REG_MEM](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Synchronization/WaitMemory.cpp) reports a diagnostic after `APS5_GPU_WAIT_TIMEOUT_MS` without treating the timeout as completion. An unsatisfied wait keeps polling and checking driver failures; a missing producer can therefore leave its queue waiting indefinitely. Existing recorded-label shortcuts remain in use.
 - [COND_EXEC](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Packets/PacketExecution.cpp) reads its condition after the earlier packets of its queue complete. Without PFP_SYNC_ME the console's graphics PFP reads it ahead of the ME, so a title that races the read sees a later value here.

RDNA2 hardware (measured on gfx1035) performs every lane's first exchange before any lane's second one, so when lanes of the same wave or of different waves overlap addresses, the result can differ from hardware. `offset0 == offset1` throws, although on hardware it is two exchanges in order.
 - [`ds_condxchg32_rtn_b64`](../../../core/shader/recompiler/Translation/src/MemoryInstructions/SharedMemoryInstructions.cpp) uses two 32-bit atomic conditional exchanges. RDNA2 (gfx1035) measurements confirmed aligned return values, conditional bit clearing and 16-bit offsets; out-of-range accesses return zero without modifying LDS. Misaligned accesses fault the wave on gfx1035; the recompiler does not model this fault. Radeon 780M (gfx1103, RDNA3) measurements confirmed aligned return values, conditional bit clearing, EXEC masking and operand overlap in wave32 and wave64; contended cases passed per-dword conservation checks. Contended lane ordering and gfx1013 remain unmeasured; pair-wide indivisibility is not assumed, and concurrent 64-bit LDS atomics use a separate lock. GDS throws. VGPR pairs extending beyond v255 throw; allocated-VGPR EXEC nullification is not emulated.
 - [64-bit image atomics](../../../core/shader/recompiler/Translation/src/MemoryInstructions/ImageInstructions.cpp) (`image_atomic_*` with a two-dword data mask) need `VK_EXT_shader_image_atomic_int64` and act on 32_32 UINT, SINT and FLOAT surfaces through an R64_UINT storage view. 64-bit `image_atomic_inc`, `image_atomic_dec` and the float atomics throw, as does any other access in the same shader to an image it updates with 64-bit atomics.

This is the path on a device that cannot blit R8 or RG8 to RGBA8, and with `APS5_SRGB_SHADER_DECODE=1`; otherwise a load of a sampled texture reads the RGBA8 sRGB copy and gets the device's own decode.
+- [Samples and gathers](../../../core/shader/recompiler/SpirvBackend/src/SpirvImageEmitter.cpp) of 8_SRGB and 8_8_SRGB textures read an RGBA8 sRGB copy of the texture (libSceAgcDriver, [Texture.cpp](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Texture.cpp)) on a device that cannot sample R8_SRGB or R8G8_SRGB but can blit R8 or RG8 to RGBA8, so they use that device's own decode. They still throw on a device that cannot blit, and with `APS5_SRGB_SHADER_DECODE=1`. A multisampled or depth view of these formats gets no copy.
 - [Bindless image table](../../../core/shader/recompiler/Optimization/src/ResourceMaterializer.cpp) entries of 8_SRGB and 8_8_SRGB textures read zeros, like converted formats, on a device that cannot sample R8_SRGB or R8G8_SRGB.
 - [Shader MODE register access](../../../core/shader/recompiler/Translation/src/RoundingMode.cpp) starts from the rounding fields of `GuestContext::floatMode` and follows immediate rounding writes (`s_round_mode`, `s_setreg_imm32_b32` on MODE bits 0-3) through the control flow graph; `s_getreg_b32` of those bits returns the tracked value. Only `v_cvt_f32_i32`, `v_cvt_f32_u32`, `v_ldexp_f32`, the f16 conversions and `v_ldexp_f16` (with f16 denormals kept) and the instructions that already read `FLOAT_MODE` follow a rounding mode set at run time; any other float instruction that runs while a directed rounding mode differs from the initial one throws at that instruction. Rounding bits written from an SGPR (`s_setreg_b32`) or that differ between the paths reaching an instruction throw where they are read or used. A shader without `FLOAT_MODE` metadata throws on any rounding change. Non-rounding register reads still throw; `s_setreg_b32` writes to other hardware registers are still ignored. Tests follow the public RDNA2/LLVM contract, not console measurements.
 - A [flat SRT read](../../../core/shader/recompiler/Optimization/src/SrtWalker/SrtDescriptorEvaluation.cpp) through a null or unmapped pointer loaded from memory raises a [BDA fault](../../../core/libs/prx/libSceAgcDriver/Graphics/src/BdaResources.cpp) only if the program executes it, then stops or reads zero like a BDA read.

Subject: [PATCH 0986/1000] fix(libkernel): report the accept queue length for
 a listening socket's read event

A read event on a listening socket took its data from FIONREAD, which a listening socket refuses on Linux, so kevent and sceKernelAddReadEvent reported 0 connections while saying one was ready. FreeBSD 11.4 gives a listening socket filt_solisten, which reports so_qlen, the completed connections waiting for accept. Ready now checks SO_ACCEPTCONN and on Linux reads a TCP listener's accept backlog from TCP_INFO, where tcp_get_info puts it in tcpi_unacked; with no host call for the count (Windows, macOS, a listener that is not TCP) it reports 1, the lower bound the readiness already implies.

Only the exact paths are recognised, `fstat`, `lseek` and `mmap` see the null device, and opening them for writing throws
 - [pthread_attr_getinheritsched, pthread_attr_setinheritsched, pthread_attr_getscope, pthread_attr_setscope, pthread_attr_getstackaddr](../../../core/libs/prx/libkernel/Pthread/Posix/Attr.cpp) (libkernel) follow FreeBSD 11 libthr ([thr_attr.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_attr.c), [thr_create.c](https://github.com/freebsd/freebsd-src/blob/5ed7eb0d97ba4436218e810f61bd059acba984c2/lib/libthr/thread/thr_create.c)), not measured on the console: the scope defaults to `PTHREAD_SCOPE_SYSTEM` (2), only it and `PTHREAD_SCOPE_PROCESS` (0) are accepted and other values return `EINVAL`, and an inherit value other than `PTHREAD_INHERIT_SCHED` (4) or `PTHREAD_EXPLICIT_SCHED` (0) returns `ENOTSUP`. `pthread_attr_getstackaddr` returns the configured stack address pointer (null by default). A null output of `pthread_attr_getinheritsched` throws, since libthr writes through it unchecked. A thread keeps the scope it was created with, taken from the creating thread under `PTHREAD_INHERIT_SCHED`, and `pthread_attr_get_np` and `scePthreadAttrGet` report it, but every guest thread is a host thread at system scope, so process scope changes nothing
 - [Shared memory](../../../core/libs/prx/libkernel/File/src/SharedMemory.cpp) (libkernel) on Linux implements anonymous and named objects, bounded descriptor writes and seeks, and `shm_unlink` with effective read/write permission checks from FreeBSD 11. Named paths up to 1023 bytes use `/anyps5-shm-` plus SHA-1; collisions are not detected, and the namespace is shared across processes in the host mount namespace. Named creation applies the guest umask without changing the host mask. Linux procfs and `/dev/shm` are required. Operations use an advisory directory lock; external host operations bypass it, unrelated objects serialize, and descriptor operations require two spare host descriptors and compare device/inode with the initial descriptor identity on both the pinned-object and ordinary-file fallback paths. [Guest mappings](../../../core/libs/prx/libkernel/DirectMemory/PosixMemory.cpp) support shared and private mappings of these descriptors through the allocation tracker and pin a duplicate descriptor during validation and mapping; mapping requires one spare host descriptor; file-backed mappings use the write-watch scan fallback because aliases and descriptor writes bypass per-mapping tracking. Named objects and file-backed mappings on Windows remain unsupported. Invalid non-null name pointers, console behaviour and title compatibility remain unverified.
-- [sceKernelAddReadEvent and sceKernelAddWriteEvent](../../../core/libs/prx/libkernel/Equeue/Equeue.cpp) (libkernel): a write event reports the free space of the socket's send buffer in `data`, as FreeBSD 11.4's [`filt_sowrite`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c#L3358-L3382) reports `sbspace`: on Linux the host's `SO_SNDBUF` less the bytes `SIOCOUTQ` counts as queued, which include the host's per-packet overhead, so the space shrinks by somewhat more than the bytes sent. Windows has no query for that space and macOS is not wired up, so both report the whole `SO_SNDBUF`, which does not shrink as data is queued. Only guest sockets are supported; other descriptors and a low watermark above 1 throw
+- [sceKernelAddReadEvent and sceKernelAddWriteEvent](../../../core/libs/prx/libkernel/Equeue/Equeue.cpp) (libkernel): a read event on a listening socket, here and in `kevent`, reports the number of completed connections waiting to be accepted in `data`, as FreeBSD 11.4's [`filt_solisten`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c#L3384-L3392) reports `so_qlen`: on Linux a TCP listener's accept queue from `TCP_INFO` (`tcpi_unacked`, which Linux fills with the accept backlog for a listening socket), and elsewhere, or for a listener that is not TCP, 1 while a connection is waiting, as no host call reports that count. A write event reports the free space of the socket's send buffer in `data`, as FreeBSD 11.4's [`filt_sowrite`](https://github.com/freebsd/freebsd-src/blob/release/11.4.0/sys/kern/uipc_socket.c#L3358-L3382) reports `sbspace`: on Linux the host's `SO_SNDBUF` less the bytes `SIOCOUTQ` counts as queued, which include the host's per-packet overhead, so the space shrinks by somewhat more than the bytes sent.

 - [close](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) and [setsockopt](../../../core/libs/prx/libkernel/Socket/src/Udp.cpp) (libkernel) reach a [libSceNet](../../../core/libs/prx/libSceNet/Export.cpp) socket through hooks libSceNet registers, as `select` polls them; the other libkernel socket calls do not. libSceNet numbers its sockets from 32 in its own table, so a CRT file descriptor and a socket can share a number; `close` then closes the socket. On the console both are one kernel descriptor space
 - [sceKernelPread, sceKernelPwrite, sceKernelPreadv, sceKernelPwritev](../../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) on Windows transfer at the given offset with an overlapped `ReadFile`/`WriteFile` and restore the descriptor's file pointer afterwards. Guest scalar transfers, positioned transfers, vectored transfers and seeks share a position lock across duplicated descriptors; a vector holds it for the whole operation. Independently opened descriptors and other processes do not share that lock, so vector transfers over their overlapping file ranges are not coordinated. Handles that are not disk files return `ESPIPE`. A pipe or console `readv` can return a short read when no more input is available; each iovec is transferred separately, so a failure after the first transfer returns the bytes already done
 - [sceKernelAioSubmitReadCommands, sceKernelAioSubmitWriteCommands and their Multiple variants](../../../core/libs/prx/libkernel/Aio/src/Aio.cpp) (libkernel) on Windows transfer through the same positioned path as `sceKernelPread`/`sceKernelPwrite` and restore the descriptor's file pointer afterwards; positioned transfers, plain transfers and seeks of one descriptor are serialized per descriptor (shared across duplicated descriptors), so a concurrent transfer observes a stable file pointer

 - [Flip packets raise the graphics end-of-pipe event](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Packets/PacketExecution.cpp) (libSceAgcDriver) - a flip delivers the queue's end-of-pipe event (`sceAgcDriverAddEqEvent`) once the work recorded before it completes, as a `RELEASE_MEM` with `INT_SEL` does. Minecraft (PPSA17221) registers the graphics event, never requests an interrupt in its releases, and waits on the event after every flip while holding its render lock, so without this it never presents a second frame. Whether the console raises the event from the flip itself or from an interrupt its flip sequence contains is not measured; a title that waits only on release interrupts sees one extra event per flip, with `data` counting it.
 - [Host import windows and budget](../../../core/libs/prx/libSceAgcDriver/Graphics/src/GuestBufferMemory.cpp) (libSceAgcDriver): a registered range larger than 64 MiB is imported one 64 MiB window at a time for buffer and fill accesses; an access across window edges imports the cells it touches, grown to the union of the range's imports it overlaps. An address-based build (`AcquireRegistered`) imports the range whole and replaces its windows. Live imports stay under a budget: `APS5_HOST_IMPORT_MIB`, else the larger of 6 GiB and half the physical memory, at most the largest host heap less 2 GiB (imports and type-3 mirrors share it; #167's rule). A new import beyond it retires the least recently used imports not used in the last 256 lookups; one that would not fit even then is refused before anything is retired, and imports made when a range is mapped never evict. A refused import is tried again at its next use. The 64 MiB window, the 256-lookup protection and the 2 GiB reserve are choices, not measured.
 - [Registration preparation at submit](../../../core/libs/prx/libSceAgcDriver/Execution/src/Driver/Queues/Submission.cpp) (libSceAgcDriver) - `Driver::Submit` waits for every registration-time shader preparation queued before the call, not only those of the shaders the commands use, so a submission behind a long queue of unrelated preparations waits for all of them on the submitting thread. Waiting there instead of in the queue worker keeps the GPU side of a submission short: a title that sees a submission take seconds treats the GPU as hung (Goat Simulator 3, PPSA04159, then stops submitting and its garbage collector fails a 10 s timeout). On the console shaders are compiled ahead of time, so neither wait exists; how long a title tolerates a slow submit call is not known.
-- [Resource cache entries holding released textures](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) - a sampled texture the texture cache drops while something else holds it, or makes without caching (`admitTexture` refusing a first use), is marked released, and `ResourceCache::Insert` refuses descriptor sets that hold one and removes the entries that do. The removal waits for the next insert: until then `Find` still returns those entries and their textures stay alive. One process-wide flag starts the sweep, so while the sampled cache is over its budget every insert scans all entries (1,024 at start, up to 16,384 after growth, or `APS5_RESOURCE_CACHE_ENTRIES`, each with its textures); that cost is not measured. When `ReleaseTextureCaches` runs on device memory exhaustion, the sampled textures these entries hold are only marked released and are freed at the next insert, so the immediate allocation retry gets no memory back from them. A draw or dispatch whose textures the cache refused builds its descriptor sets again on each use for as long as the cache stays full; the count bounds (`APS5_RESOURCE_CACHE_ENTRIES`, `APS5_RESOURCE_CACHE_TABLE_ELEMENTS`) still bound nothing by bytes, and sampled textures made outside the texture cache (the disabled cache, depth-surface copies) are never marked. Measured only on Ghost of Yōtei (PPSA26344) on one RTX 4090: with the default bounds, sampled textures held outside the cache peaked at 2,836 MiB (7,830 MiB before) and device-local heap 0 stayed under its 22.9 GB budget for the whole run (26,357 MiB before, which aborted with `VK_ERROR_OUT_OF_DEVICE_MEMORY` at the wolf scene). Whether the extra descriptor-set builds cost frame time elsewhere is not measured.

 - [Unclamped normalized color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) - CB_COLOR_INFO targets with BLEND_CLAMP clear (bit 15) on UNORM and SNORM formats are accepted when blending is disabled (ENABLE clear or BLEND_BYPASS set). Vulkan converts unblended shader values and clamps to the normalized range automatically; blending into an unclamped normalized target remains unmodeled because Vulkan always clamps inputs prior to blending.
 
 - [Thick SW_4KB_S_X volumes](../../../core/libs/prx/libSceAgcDriver/Graphics/src/TextureTiling.cpp) use AMD addrlib's GFX10 non-RB+ 16-pipe `GFX10_SW_4K_S3_X_PATINFO` equations for 1, 2, 4, 8 and 16-byte elements, including packed mip tails. The layout follows [AMD PAL c5e80007](https://github.com/GPUOpen-Drivers/pal/blob/c5e800072a32f68b6ccc4422936d96167c6e0728/src/core/imported/addrlib/src/gfx10/gfx10addrlib.cpp); it has not been measured on console hardware. Other thick swizzle modes outside the supported families still throw. Mipmapped 3D color targets remain refused by the color-register decoder.

Subject: [PATCH 0991/1000] fix(libc): keep the app0.zar state through exit
 handlers

Every path resolution reaches the app0.zar state, which was a
function-local static: it is destroyed during exit before the handlers
registered ahead of its first use run, so a path resolved in such a
handler locked a destroyed mutex. glibc lets that pass; macOS fails it
with EINVAL, and guest_path_lifetime failed there. The state is now
allocated once and never destroyed, as the working directory state
beside it already is.

Subject: [PATCH 0993/1000] fix(libkernel): report the precommitted stack of an
 adopted thread on Windows

An adopted thread (the main thread, or a host thread that calls
scePthreadSelf) reported its whole Windows stack reservation, and so
did sceKernelIsStack on a host thread before adoption. A relinked
executable reserves 0x210000 bytes for its main thread and commits the
top 0x200000, so the lowest 64 KiB of the reported stack hold only
reserved pages and Windows' guard pages. mprotect fails there, so
HotSpot in Java 25 LAN / DNS (PPSA99869) could not create the main
thread's stack guard pages ("Attempt to allocate stack guard pages
failed").

When everything above the bottom allocation granule is committed
read-write, the host stack is now reported from there, as created
guest threads report only their committed stack. Other host stacks
keep the whole range. The committed-pages walk is shared with
StartNativeThread and throws when VirtualQuery fails.

 - [getcontext and setcontext](../../../core/libs/prx/libkernel/System/src/UserContext.cpp) (libkernel) and [makecontext](../../../core/libs/prx/libSceLibcInternal/UserContext.cpp) (libSceLibcInternal) use FreeBSD 11's amd64 `ucontext_t` (`mcontext` at 0x10, `mc_len` 800, `uc_link` at 0x330, `uc_stack` at 0x338, 0x370 bytes), the layout homebrew built against FreeBSD's headers passes: PPSA99039's OpenSSL `ASYNC` (`crypto/async/arch/async_posix.c`) captures into a 0x370-byte stack buffer. `getcontext` writes the 0x330 bytes before `uc_link`, as FreeBSD's `UC_COPY_SIZE`. The console's own layout for these functions is not verified; the exception handler's context is a different one (see `sceKernelRaiseException`)
 - [getcontext and setcontext](../../../core/libs/prx/libkernel/System/src/UserContext.cpp) (libkernel) keep the 512-byte FXSAVE image in `mc_fpstate` (x87, MXCSR, XMM0-15), so the upper halves of YMM0-15 are neither saved nor restored, and `getcontext` leaves `mc_xfpustate` and `mc_xfpustate_len` 0. `getcontext` sets `mc_fpformat` and `mc_ownedfp` to FreeBSD's `_MC_FPFMT_XMM` and `_MC_FPOWNED_FPU`, `mc_cs` and `mc_ss` to the host selectors, and `mc_flags`, `mc_fsbase` and `mc_gsbase` to 0. `setcontext` loads `mc_fpstate` whatever `mc_fpformat` and `mc_ownedfp` say, and restores neither the segment selectors, `mc_fsbase` and `mc_gsbase` nor the extended state, which FreeBSD restores when `mc_flags` asks for them
 - [setcontext](../../../core/libs/prx/libkernel/System/src/UserContext.cpp) (libkernel) and [longjmp](../../../core/libs/prx/libc/src/JumpBuffer.cpp) (libc) on Windows set the thread's stack bounds in the TEB to the stack they switch to: a `makecontext` stack, or else the committed region around the target stack pointer. A switch to any other guest stack, such as a context built by hand, gets the bounds of that region only
+- [scePthreadAttrGet, pthread_attr_get_np and sceKernelIsStack](../../../core/libs/prx/libkernel/Pthread/src/Thread.cpp) (libkernel) report the stack of a host thread the library did not create, on Windows, from one allocation granule (64 KiB) above the bottom of its reservation when everything above that is committed read-write, as in a relinked executable's main thread and its default-size host threads (0x200000 committed of 0x210000 reserved), so the guest can protect the lowest reported pages, as HotSpot does for its stack guard pages in Java 25 LAN / DNS (PPSA99869). Any other such thread, and every such thread on Linux, gets its whole host stack: on Windows `mprotect` commits its reserved lower pages before protecting them and drops the guard flag of Windows' guard pages, and on Linux it cannot change the unmapped lower pages
 - [sceKernelInstallExceptionHandler](../../../core/libs/prx/libkernel/System/src/Exception.cpp) records the handler, but a host fault still ends the process: only signals raised with `sceKernelRaiseException` are delivered. Unity's PS5Util module installs a SIGUSR1 handler that reads `uc_mcontext.mc_rsp` (offset 0xf8 of the context) and raises SIGUSR1 on other threads to stop them for garbage collection
 - [sceKernelRaiseException](../../../core/libs/prx/libkernel/System/src/Exception.cpp) on Linux sends the host SIGUSR1, which the library takes over, to the target thread, so the handler runs wherever the thread was interrupted, emulator code included. On the console kernel objects are system calls and libthr defers signals while a thread holds its internal locks; here a handler that needs a host lock the interrupted code holds deadlocks, and a thread that the handler keeps waiting keeps its host locks. Host waits resume after the handler. The host calls Linux does not restart end early: sleeps that do not retry return before their time, and the poll of `sceNetEpollWait` and socket calls with a send or receive timeout return `EINTR` to the guest
 - [sceKernelRaiseException](../../../core/libs/prx/libkernel/System/src/Exception.cpp) builds the handler's `ucontext` with FreeBSD's amd64 layout (16-byte sigmask, `mcontext` at 0x40, `mc_rsp` at 0xf8); the console's layout is not verified beyond the fields PS5Util reads

Subject: [PATCH 0997/1000] fix(shader): act on the containing dword for
 unaligned 32-bit buffer atomics

The RDNA2 ISA (8.1.7) ignores the two low address bits of dword or wider
non-formatted accesses in alignment mode DWORD. MXGP 26 (PPSA30839) sets
bits with buffer_atomic_or at odd byte offsets, which recorded an
unaligned BDA fault and dropped the atomic. A 32-bit buffer atomic now
acts on the dword that holds its address; 64-bit atomics off an 8-byte
boundary still fault.

The returned value is always the old value as it was in memory. `IEEE_MODE` has no effect. The same bit rule serves the buffer float atomics (`AtomicFloatBits`). Not measured: a denormal or signalling-NaN `data1` of `cmpst` (stored as given). `ds_add_f32` and `ds_add_rtn_f32` follow RDNA1 (gfx1010, RX 5700 XT), measured with the [hardware oracle](../HW_ORACLE.md) template run through the Windows driver's comgr and HIP runtime over 1574 operand pairs (signed zeros, denormals, the smallest normals, infinities, quiet and signalling NaNs with payloads, the largest normals, random pairs near the denormal range and pairs that nearly cancel) in all 16 combinations of the f32 denormal field and the f32 round mode, and at IEEE 1 and DX10 clamp 0: both operands are flushed to a signed zero when bit 0 of the field is clear and the result when bit 1 is clear, the sum is rounded to nearest even whatever the round mode, a NaN data operand is stored quieted, else a NaN old value is stored quieted, `+inf + -inf` stores 0xffc00000, and `IEEE_MODE` and `DX10_CLAMP` have no effect. The sum is the host's `OpFAdd` between those flushes, so where the field keeps f32 denormals the result also depends on the host preserving them, which the module does not request. thuanquang measured the same rule on RDNA2 (gfx1031, RX 6700 XT) in #5492, with the same operand classes and 18 modes in wave32 and wave64; the PS5's gfx1013 is not measured.
 - [LDS in pixel, vertex-path and fetch programs](../../../core/shader/recompiler/SpirvBackend/src/SpirvAnalysis.cpp) (shader recompiler) - is an array private to each host invocation, in `Function` storage, as only compute and mesh programs get workgroup memory; on the console one LDS region is shared by the wave (RDNA 2 ISA sections 3.6.6 and 10.4), so a lane does not see another lane's LDS writes. Sub-dword writes (`ds_write_b8`, `ds_write_b16` and their `_d16_hi` forms), the 32-bit LDS atomics, `ds_append` and `ds_consume` load, update and store the invocation's own dword without an atomic, as Vulkan allows atomics only on `Uniform`, `Workgroup`, `Image`, `StorageBuffer`, `PhysicalStorageBuffer` and `TaskPayloadWorkgroupEXT` pointers (VUID-StandaloneSpirv-None-04686). `ds_append` and `ds_consume` update only the first active lane's copy and return its old value to every lane, so a second append after the first active lane changes, or a read of the counter by another lane, differs from the hardware. Not measured on hardware.
 - [V# bases off a DWORD boundary](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - raw accesses use the exact bytes and `s_buffer_load` reads `(base & ~3) + (offset & ~3)`, as measured on gfx1035 (Linux, alignment mode UNALIGNED; the console's mode is unknown). Formatted accesses off their element's alignment throw. Atomics use the byte address `base + offset`, base's low two bits included: measured on RDNA2 (gfx1031, Radeon RX 6700 XT, AMD Windows driver 32.0.21045.5002 through HIP) with `buffer_atomic_add`, `buffer_atomic_swap` and `buffer_atomic_cmpswap` and bases 0 to 3 bytes past a DWORD boundary with offsets 0 to 7, an address on a DWORD boundary updates that DWORD and returns its old value, and any other address stops the dispatch, which the recompiler reports as an unaligned access fault.
+- [Unaligned 32-bit buffer atomics](../../../core/shader/recompiler/SpirvBackend/src/SpirvRuntimeBuffer.cpp) (shader recompiler) act on the dword that holds their address, as section 8.1.7 of the [RDNA2 ISA](https://gpuopen.com/download/rdna2-shader-instruction-set-architecture.pdf) describes for alignment mode DWORD ("the two LSBs of the byte-address are ignored, thus forcing Dword alignment"). The mode comes from `SH_MEM_CONFIG.alignment_mode`, and the console's mode is unknown. MXGP 26 (PPSA30839) sets bits with `buffer_atomic_or` at odd byte offsets, so the console is not in a strict mode, where section 3.11 reports a memory violation for a misaligned atomic. In mode UNALIGNED, which Linux KFD sets, a misaligned atomic stops the dispatch (measured on gfx1031 and gfx1036), so the console is not in that mode either. A 64-bit buffer atomic off an 8-byte boundary still records an unaligned BDA fault: mode DWORD would align it only to 4 bytes, which a host 64-bit atomic cannot address. Covered by [BufferAtomicUnaligned.cpp](../../../core/libs/prx/libSceAgcDriver/tests/execution/BufferAtomicUnaligned.cpp).
 - [32-bit bitfield masks](../../../core/shader/recompiler/Translation/src/IntegerInstructions.cpp) (`S_BFM_B32`, `V_BFM_B32`) use the truncating 32-bit shift specified by the [RDNA 1.0 ISA](https://www.amd.com/content/dam/amd/en/documents/radeon-tech-docs/instruction-set-architectures/rdna-shader-instruction-set-architecture.pdf), sections 12.1 (opcode 36) and 12.12 (opcode 867). Width and offset use their low five bits. This matches gfx1035 (Linux) for every width/offset pair, with and without upper operand bits set, and both leave SCC unchanged; not measured on the console.
 - [Vector buffer offsets that are not a multiple of 4](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) (shader recompiler) - dword accesses count whole dwords from the V# base, where the hardware reads the exact bytes at base + offset.
 - [Raw `buffer_load_dwordx2`](../../../core/shader/recompiler/SpirvBackend/src/SpirvMemory/SpirvMemoryInstructions.cpp) is one 64-bit access on the hardware (with or without glc), so it never sees half of a `buffer_atomic_swap_x2`. Only a glc load that is 8-byte aligned and in bounds, in a program that has the 64-bit storage view (it uses 64-bit buffer atomics), is read with one 64-bit atomic load; every other dwordx2 load is two dword loads and can tear against a concurrent 64-bit write: loads without glc, and loads in a program without 64-bit buffer atomics while another shader writes the pair with `swap_x2`.

 - [Per-face depth bias](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver): Vulkan has one depth bias per draw, so a draw that rasterizes both faces with different front and back bias (PA_SU_SC_MODE_CNTL, PA_SU_POLY_OFFSET_FRONT/BACK_*) is recorded twice, front faces with the back faces culled and then back faces with the front faces culled. The vertex stages run twice, so a vertex shader that writes memory writes twice, and all front faces land before all back faces instead of in primitive order, which differs only for blending or stencil updates that depend on the order.
 - [Draw recipes with depth targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver): direct draw recipes record and replay with active depth targets, matching the bound depth surface view by its target view identity; altered depth surface addresses or incompatible view handles trigger a recipe miss and pipeline rebuild.
 - [Partial rect-list primitives](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver): a rect-list draw whose vertex or index count is not a multiple of 3 draws its complete rectangles and leaves out the 1 or 2 vertices after them, because rect lists are drawn as Vulkan patch lists of 3 control points, which generate [⌊vertexCount/3⌋ patches](https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#drawing-patch-lists). What the console draws for the incomplete rectangle is not measured; Palworld (PPSA23126) draws 4 vertices × 9 instances as a rect list when its character creation opens.
+- [8_8 UINT color targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver) decode as `R8G8_UINT` with the same component-swap mapping as 8_8 UNORM/SNORM (`0xe4` / `0xec`). Follows the existing 8 and 8_8_8_8 UINT paths; not measured on the console. RetroArch (PPSA99169) uses it during menu startup.
 - [Separate alpha blend into 8_8 SWAP_ALT targets](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Pipeline.cpp) (libSceAgcDriver): the second channel of a two-channel target with `COMP_SWAP` 1 holds the alpha export, but Vulkan blends it with the color equation of the R8G8 attachment, so a draw whose alpha equation differs from its color equation is recorded twice, the first channel with the color equation and the second with the alpha factors and operation moved into the color equation. The vertex stages run twice, so a vertex shader that writes memory writes twice, and occlusion counts include both passes. Draws that write depth or stencil, pixel shaders that write memory and factors of the destination alpha throw. That the hardware blends the second channel with the alpha equation is taken from Mesa's `si_translate_colorswap` and radeonsi's use of it for luminance-alpha formats, not measured on hardware.
 - [Unexported pixel inputs](../../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderInputState.cpp) (libSceAgcDriver): a pixel input whose `SPI_PS_INPUT_CNTL` parameter the previous stage does not export is programmed as a default-value input (`OFFSET` bit 5, `DEFAULT_VAL` 0, FP16 high half too) and reads (0, 0, 0, 0), as radeonsi's `SI_PS_INPUT_CNTL_UNUSED` does and as rect-list draws already do. The console's value for an unwritten parameter cache entry is not measured on hardware.
 - [Per-sample pixel shading](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (libSceAgcDriver): `PA_SC_MODE_CNTL_1.PS_ITER_SAMPLE` (bit 16, [PS5_Mesa GFX10.3 registers](https://github.com/mihawk-99/PS5_Mesa/blob/0b2d6d1a61d9bbf89cf8beb88a696144f67c61f8/src/amd/registers/gfx103.json)) on a multisampled draw enables Vulkan sample shading with a minimum rate of 1.0, so the pixel program runs once per sample. The draw throws when the device lacks `sampleRateShading`. On a single-sample draw the bit has no effect and is dropped. That the console runs the pixel program once per covered sample, and what it does with the other multisample registers in that mode, is taken from the register name and Vulkan's definition, not measured on hardware.

Subject: [PATCH 1000/1000] fix(relinker): report processor 0 from RDTSCP under
 --to-rosetta

Rosetta sets RDTSCP's ECX to its constant TSC_AUX, 0xAAAAAAAB, which is
not a processor index. --to-rosetta already makes RDPID return processor
0 for the same reason, so code reading the processor through RDTSCP saw
a different value from code reading it through RDPID.

--to-rosetta now moves RDTSCP into an optional stub that runs the
instruction unchanged and then loads 0 into ECX with a MOV, which
leaves the counter in EDX:EAX and the flags as they were. A site with no
movable instruction after it for the jump is kept, as for RDPID. The
Intel target and a plain relink are unchanged.

 - In executables and guest modules with a `PT_SCE_DYNLIBDATA` segment, the [code analysis](../../../core/relinker/relinker/src/analysis/CodeInstructionCollector.cpp) of the Windows and macOS outputs follows code only from the end of `PT_INTERP`, or of the `/libexec/ld-elf.so.1` string that begins the segment when no `PT_INTERP` covers it, as in OpenOrbis modules, to the end of the PLT after the last function of the unwind table, the end the pipeline's scans above use; a guest module with PLT relocations and no PLT after its last unwind function fails as the executable does. Code after that PLT is not analyzed: a TLS access in it is not rewritten, an entry point or pointer into it is ignored, and a function symbol or init/fini array entry pointing into it fails the conversion.
 - A relocation against a dynamic symbol entry that is all zero, like the null symbol, takes the value 0 plus its addend, as the gABI defines for `STN_UNDEF` ([pipeline](../../../core/relinker/relinker/src/pipeline/RelinkerPipeline.cpp)). The Linux output imports such an entry as an unnamed weak symbol, which the host loader resolves to 0; the Windows and macOS outputs write the value into the slot ([relocation builder](../../../core/relinker/elfpatcher/src/windows/WindowsRelocationBuilder.cpp)). What the console's loader does with such an entry is not measured. OliSe Player (PPSA01153) has seven of them, and its code calls through those slots only when they are not 0 ([#4437](https://github.com/boykopovar/AnyPS5/issues/4437)).
 - The Linux placement of the `--to-intel` stubs in the [ELF patcher](../../../core/relinker/elfpatcher/src/linux/LinuxElfPatcher.cpp) is covered only by a synthetic test.
-- `--to-rosetta` lowers what Rosetta lacks on top of `--to-intel` ([matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp)). AVX2, FMA, BMI1/2, F16C and MOVBE were observed to execute on an M5 Max without being reported through CPUID; this is not a guarantee for other Rosetta hosts. ANDN and RDRAND fault on an M1 running macOS 15.3.1 and execute on an M1 running macOS 26.6.2, so on the M1 the difference follows the macOS version; on that host BEXTR, BLSI, BLSMSK, BLSR, TZCNT, LZCNT, POPCNT, BZHI, MULX, PDEP, PEXT, RORX, SARX, SHLX, SHRX, MOVBE, FMA, AVX2 and F16C execute as well, its CPUID leaf 1 reports none of MOVBE, FMA, AVX or F16C, and RDSEED, RDPID, CLWB, ADCX and ADOX raise SIGILL. They also execute on an M5 running macOS 26.4, where the rest of BMI1 and BMI2, LZCNT, PREFETCHW, CLFLUSHOPT, AVX, AVX2, FMA, F16C and MOVBE execute as well although CPUID leaf 7 reads zero and leaves 1 and 0x80000001 report none of them, and where RDSEED, CLWB, RDPID, ADCX and ADOX raise an illegal instruction. ANDN is lowered, but RDRAND and other BMI instructions still depend on the host. RDSEED becomes RDRAND and CLWB a NOP. RDPID returns processor 0, because Rosetta's TSC_AUX is the constant 0xAAAAAAAB; the same value reaches RDTSCP's ECX, which is not converted. ADCX/ADOX fault under Rosetta and are not converted: compilers do not emit them, and code that checks CPUID sees no ADX. The conversions are covered by the converter tests. ANDN lowering is also executed by an x86-64 test build under Rosetta on the M1; the other conversions were originally checked on an M5 Max, outside this repository's CI.
+- `--to-rosetta` lowers what Rosetta lacks on top of `--to-intel` ([matcher](../../../core/relinker/codegen/src/x86/Amd64OnlyInstructionMatcher.cpp)). AVX2, FMA, BMI1/2, F16C and MOVBE were observed to execute on an M5 Max without being reported through CPUID; this is not a guarantee for other Rosetta hosts. ANDN and RDRAND fault on an M1 running macOS 15.3.1 and execute on an M1 running macOS 26.6.2, so on the M1 the difference follows the macOS version; on that host BEXTR, BLSI, BLSMSK, BLSR, TZCNT, LZCNT, POPCNT, BZHI, MULX, PDEP, PEXT, RORX, SARX, SHLX, SHRX, MOVBE, FMA, AVX2 and F16C execute as well, its CPUID leaf 1 reports none of MOVBE, FMA, AVX or F16C, and RDSEED, RDPID, CLWB, ADCX and ADOX raise SIGILL. They also execute on an M5 running macOS 26.4, where the rest of BMI1 and BMI2, LZCNT, PREFETCHW, CLFLUSHOPT, AVX, AVX2, FMA, F16C and MOVBE execute as well although CPUID leaf 7 reads zero and leaves 1 and 0x80000001 report none of them, and where RDSEED, CLWB, RDPID, ADCX and ADOX raise an illegal instruction. ANDN is lowered, but RDRAND and other BMI instructions still depend on the host. RDSEED becomes RDRAND and CLWB a NOP. RDPID returns processor 0, and RDTSCP runs unchanged with ECX set to 0 after it, because Rosetta's TSC_AUX is the constant 0xAAAAAAAB (also measured on an M5, macOS 27.0.1). An RDPID or RDTSCP site with no movable instruction after it for the jump is kept; a kept RDTSCP reports 0xAAAAAAAB. ADCX/ADOX fault under Rosetta and are not converted: compilers do not emit them, and code that checks CPUID sees no ADX. The conversions are covered by the converter tests. ANDN lowering is also executed by an x86-64 test build under Rosetta on the M1; the other conversions were originally checked on an M5 Max, outside this repository's CI.
 - `--to-intel` replaces the approximate legacy SSE and VEX.128 register forms of RSQRTPS/RCPPS and VRSQRTPS/VRCPPS with [correctly rounded](../../../core/relinker/codegen/src/x86/ReciprocalLowering.cpp) 1/sqrt(x) and 1/x, not with the AMD approximation: its tables are not public. Intel's approximation of 1/sqrt(1.0) is 0x3F7FF000, and two Newton-Raphson steps on it settle on 0.99999994 instead of 1.0; a renormalised identity quaternion then turns into a NaN axis in PPSA21564, which the console does not show. Refined results now reach the exact value; unrefined ones can still differ from the console in the low bits. Each site costs an out-of-line stub (two jumps, a spill below the red zone, SQRTPS/DIVPS). Legacy SSE forms preserve the destination's upper YMM bits; VEX forms clear them. The 256-bit, scalar and memory forms keep the native instruction, as does a site shorter than 5 bytes with no movable instruction after it for the jump (5 sites in PPSA21564, counted before a following RIP-relative instruction could move into the stub; not recounted).
 - `--trace-imports` ([entry stub](../../../core/relinker/elfpatcher/src/windows/WindowsEntryStubBuilder.cpp)) exists for Windows output only. Only imports bound through a PLT slot, or through a GOT slot whose symbol is a function, are traced; a function reached through any other relocation, or looked up at run time with `sceKernelDlsym`, is not, and neither are weak imports or the imports of modules loaded at run time
