Pixel, vertex-path and fetch programs keep LDS in a Function-storage
array private to each invocation. Sub-dword LDS writes (ds_write_b8,
ds_write_b16 and their _d16_hi forms), the 32-bit LDS atomics and
ds_append/ds_consume still emitted OpAtomicLoad, OpAtomicCompareExchange
or OpAtomicIAdd on that array, with Workgroup scope and a Workgroup
OpMemoryBarrier. Vulkan allows atomics only on Uniform, Workgroup,
Image, StorageBuffer, PhysicalStorageBuffer and TaskPayloadWorkgroupEXT
pointers (VUID-StandaloneSpirv-None-04686) and Workgroup memory scope
only in compute, mesh, task and tessellation control
(VUID-StandaloneSpirv-None-07321). With ANYPS5_ENABLE_SPIRV_TOOLS the
recompiler rejected such shaders; without it the invalid module went to
the driver.
InFunctionStorage now names the storage EmitMemoryElementPointer picks.
For Function storage, StoreSubwordInBounds, Atomic32, EmitAtomicUpdate,
SharedAtomicUpdate and AppendConsume load the dword, compute the new
value and store it, as scratch already did. The array belongs to one
invocation, so no other invocation can observe the dword in between.
Atomic32 takes the next value from AtomicNext32, which FlatAtomicNext32
now shares for its plain integer operations. The per-invocation LDS
model and what it means for ds_append are recorded as technical debt.

sceAgcSetAmmSemaphoreMemory(memory, sizeInBytes) registers the AMM semaphore memory once and zeroes the first 8 bytes of each 32-byte label; sceAgcGetSemaphoreLabel(index, label) writes memory + 32 * index for an index inside the registered memory.
Unblocks New Joe & Mac Caveman Ninja (PPSA02801) which imports both symbols. Matches OpenAGC and sharpemu agreements on signatures, 16 KiB alignment, 32-byte stride, and zeroed label counters.
A failing _Pad primitive threw a host std::runtime_error, which no guest
catch can see. threadcall.cpp calls the checked wrappers of xthread
(_Mtx_lockX, _Cnd_waitX, _Thrd_startX), which pass a non-success code to
_Throw_C_error: _Thrd_nomem and _Thrd_timedout become
resource_unavailable_try_again, _Thrd_busy device_or_resource_busy and
_Thrd_error invalid_argument, raised through _Throw_Cpp_error, which main
now implements. A failing thread start is _Thrd_startX's
resource_unavailable_try_again.
_Release now wakes the launching thread with _Cnd_signal, as
threadcall.cpp does; libc has it since the pad was written.
guest_ampr_threads checks, in a forked child whose guest terminate
handler reports the thrown object, that _Release on the thread still
holding the pad's mutex throws std::system_error with EBUSY. It fails
with the previous host exception and with busy mapped to
invalid_argument.
Implement _ZNSt4_PadC2Ev, _ZNSt4_PadD2Ev, _ZNSt4_Pad7_LaunchEPP7pthread
and _ZNSt4_Pad8_ReleaseEv, which Deathloop (PPSA01670) and Minecraft
Legends (PPSA05510) import from libSceAmpr for the std::thread launch path.
The algorithm and object layout follow Dinkumware V6.00 thr/xthread and
thr/threadcall.cpp of Visual C++ 2013 (ganboing/crt.vc12 f1d47126): a
vtable pointer whose first slot is the pure virtual _Go(), then the
condition and mutex handles and bool _Started (0x8, 0x10, 0x18), with the
console's pointer-to-slot handles of libc Threads.cpp (#3079). The pad
uses libc's _Cnd_*/_Mtx_* exports, starts the guest thread with
pthread_create and an entry that calls _Go() and returns its result as
the exit code, as _Call_func does. The unverified layout, thread
attributes and error reporting are recorded in TechnicalDebt.md.

Implement getservbyname (H1bArJPagV0) in libScePosixForWebKit. Cloud
Play (PPSA99600) imports it from this library only (registry index 408,
call site 0x1042124); once fnmatch (#3545) is in, its predicted load
stop is:
FAIL: unresolved ELF import H1bArJPagV0 from libScePosixForWebKit.prx
The ps5-payload-dev SDK stubs (f5d40f02, sce_stubs/) declare
getservbyname in libScePosixForWebKit.c and not in libkernel.c or
libSceLibcInternal.c. The call site is the service-name branch of a
getaddrinfo inside the title: a non-numeric service is looked up with
protocol "tcp", "udp" or "sctp" and the port is read big-endian at
offset 16 of the result, which fixes the servent layout used here
(name, aliases, 32-bit port, protocol at 0, 8, 16, 24).
The guest has no /etc/services and the console's file is unknown, so the
function searches 37 lines of FreeBSD 11.4 etc/services (8c639945):
ftp-data, ftp, ssh, telnet, smtp, domain, tftp, http, pop3, ntp, imap,
https, rtsp, submission, imaps and pop3s with their aliases and
protocols, in file order. None of their names or aliases appears on an
earlier line of the full file, so these lookups answer as the full file
would. The search follows files_servent in lib/libc/net/getservent.c
(8c639945): exact, case-sensitive match on the name or an alias, a null
protocol takes the first match, the port in network byte order, the
result in per-thread storage like getserv's NSS TLS state. Any other
name returns null without touching errno, as for a name the file lacks.
The repository's getaddrinfo still resolves service names through the
host, so there was no table to share; this is recorded in
TechnicalDebt.md.

Admit PA_SC_AA_CONFIG bit29 only without active perspective or linear centroid inputs, or with a skipped pixel program. Active/unspecified centroid inputs and unrelated AA fields remain refused. Source: pinned PS5_Mesa 0b2d6d1a GFX10.3 schema/RADV producer; existing ENA/ADDR intersection. Console covered-centroid interpolation remains unmeasured.
Full build/all 124 runtime libraries, conventions and registration pass. Final Windows suite: 965 pass, zero fail, seven skips of 972. Isolated state test passes 20 repeats and fails 5/5 with main State.cpp; four guard mutants fail 5/5 each. Original two title register captures reproduce the main refusal and pass this check with candidate, five times each. NVIDIA relevant groups pass; AMD draw-cache failure also occurs on unchanged main and is reported in issue4435.
AI-assisted: Codex.
TessellationLowering refused every domain-program read of the off-chip
ring outside its patch's control points, so domain programs that read
the hull's patch constants, like the quad terrain domain in Ghost of
Yotei at 0x8000 - 208 * (rel + 1), aborted.
Such reads now lower to a new PatchInput kind and become Patch inputs.
Hull outputs and domain inputs place a constant by its off-chip address
modulo the record stride, in a record-sized array at location
ceil(hsStride / 16); each program derives both on its own, so the two
interfaces match although they compile separately. Domain reads at an
address that does not move with the relative patch, across more than
one record or inside the control-point region still throw, as does a
domain program that reads patch constants but no control point. Hull
patch-constant writes now take the same bound: above the control points
of all NUM_PATCHES patches, not just one patch's.
8 MiB window, so a range larger than the window is always imported alone. A
buffer bound across two such ranges then has no import and is copied whole on
every use: PPSA25344 binds a 368 MiB buffer across a 320.75 MiB and a 47.3 MiB
range and copies it on almost every frame.
When UploadFinish meets such a region, it imports the run of the ranges the
region crosses, provided every one of them is larger than the window, and
retires their own imports. It does this before any region of the build
confirms an import, so the retire moves the epoch ahead of every pointer the
build would use. A range that large is registered whole, not grown in 64 KiB
pieces like a heap, so the joined import is not re-imported as a heap grows; it
stands in refreshImports while exactly its ranges stand. A later join that
reaches a joined import takes it in, so two joins that share a range never
retire each other in turn.

Every native save reported SAVE_DATA_BLOCKS_MAX blocks, all of them free,
in the sceSaveDataDirNameSearch infos and in sceSaveDataGetMountInfo,
whatever the title created it with and whatever its files held. A save's
size is now the blocks of the sceSaveDataMount3 call that created it,
kept beside the save; a save without a kept size takes that of its next
mount that names one, and otherwise keeps SAVE_DATA_BLOCKS_MAX. Free
blocks are what the save's files leave of it, each file rounded up to
32 KiB blocks, and the blocks and free-blocks sort keys use both.

ES-DE in RetroArch (PPSA99169) imports tzname from libSceLibcInternal and
fails to load without it; ICU's uprv_tzname reads it after localtime. It
points at the host's zone names and tzset refreshes it.

sceKernelConvertUtcToLocaltime and sceKernelConvertLocaltimeToUtc returned
the time unchanged while libc localtime follows the host zone, so a title
that mixes them shows UTC as local time (#5067).

On a PS5 (firmware 13.60) pthread_setschedparam and
scePthreadSetschedparam accept only SCHED_FIFO and SCHED_RR with a
priority of 256 to 767 or 896 to 959, return EINVAL otherwise, and
keep the policy for pthread_getschedparam. A created thread takes the
policy of explicit scheduling attributes, or its creator's when it
inherits. Here any policy and priority were accepted and SCHED_FIFO
was always reported.

Allow calling threads to query and set affinity using their own thread ID in addition to -1. Return ESRCH for non-matching thread or process IDs and EINVAL for invalid level/which arguments instead of throwing NotImplemented, matching FreeBSD cpuset semantics.
Main refuses every storage view of a depth or stencil plane that is not
2D. A 2D array view is now taken as the plane only at layer 0 with one
layer; a view with more layers or another base layer still throws.
A one-layer 2D array view replaces a 2D view of the plane like any other
view, so a store back through the replaced 2D view throws. The depth
storage dispatch test runs one-layer views of both planes and checks
that the depth and stencil tests see what they stored, and that a
two-layer view still throws.
strftime handed most conversions to the host's strftime, which differs
from FreeBSD 11's for E and O modifiers on conversions glibc does not
pair with them (%Ea was printed literally), padding flags on %+ and %v,
years outside 1000 to 9999 (%Y printed 899 and -1 where FreeBSD prints
0899 and -001), and out-of-range fields (%I of hour 100, %u of weekday
8). On Windows the padding flags printed nothing. strftime now follows
FreeBSD 11 strftime.c with the C locale on every host, and asctime
follows FreeBSD 11 asctime.c, padding years to four digits and setting
longer years apart.

A package with no playgo-* file in sce_sys has no PlayGo data, so only chunk 0
is valid and any other id returns SCE_PLAYGO_ERROR_BAD_CHUNK_ID. A package with
playgo-scenario.json but no chunk table (PPSA01748) keeps accepting every id.
A chunk table (playgo-chunk.dat or playgo-chunkdefs.xml) still decides when it
exists. A sce_sys that holds other playgo-* files without a chunk table or a
scenario file, or a playgo-chunk.dat that is not a plgx table with a nonzero
count, throws naming the file, since no such dump is known.
Without this a title that walks the ids until the first error (Sifu PPSA03001)
never gets the error.

Three catalog titles stop on Windows when they poll a guest socket for
POLLPRI|POLLOUT to see whether a non-blocking connect has completed:
- PPSA97510 PSXS5 (socket 0x10000002, thread gamedb, 13 s):
what(): poll: POLLPRI is not supported by WSAPoll
- PPSA98510 SwanStation (sockets 0x10000003/0x10000002, threads gamedb
and update): what(): poll: POLLPRI is not supported by WSAPoll
- PPSA99003 ProsperoTV ({0x10000001, POLLPRI|POLLOUT} at 5.3 s):
what(): poll: POLLPRI is not supported by WSAPoll
FreeBSD's sopoll_generic (sys/kern/uipc_socket.c, freebsd-src 8c639945)
reports POLLPRI and POLLRDBAND alike, only while out-of-band data is
pending (so_oobmark or SBS_RCVATMARK). WSAPoll rejects POLLPRI in events
with WSAEINVAL but reports pending urgent data as POLLRDBAND, so on
Windows the guest POLLPRI is now asked of WSAPoll as POLLRDBAND and
POLLIN as POLLRDNORM (Winsock's POLLIN includes POLLRDBAND, which would
report urgent data as readable). Measured on this host: WSAPoll reports
POLLRDBAND after a peer's send(MSG_OOB), waits for it, and clears it once
the byte is read with MSG_OOB. Linux keeps polling POLLPRI on the host.
select needs no change: libkernel's select passes exceptfds as Urgent to
the libSceNet poller, which already asks WSAPoll for POLLRDBAND, and it
does not take libkernel guest sockets on either host.
The guest send and recv refuse MSG_OOB, so urgent data only comes from a
peer outside the guest's sockets; guest_poll now sends it from a host
socket and checks that a connected pair and a non-blocking connect
report POLLOUT and not POLLPRI. TechnicalDebt records where Winsock's
answer differs from FreeBSD's once the stream passes the mark.
Depends on #3649 (poll on file descriptors), whose two commits this
branch carries, since the titles reach this stop only with it.
