With --trace-imports the entry stub resolves TraceImport_nid_no_patch
in libc.prx and passes each function import through it before writing
the slot: every PLT slot, and a GOT slot only when the original symbol
is a function, so data imports such as __stdoutp keep their address.
Without the option the output is unchanged.

FFmpeg resamples narrowband SILK (TOC configurations 0-3) from 8 kHz and
holds back 24 samples of the first narrowband packet after the decoder
starts or after a packet of another bandwidth: a 20 ms packet decodes to
936 samples and the next wider packet to 984. sceOpusDecDecode required
exactly the packet's duration and threw, so ProsperoRadio aborted on a
narrowband Opus station.
The decoder now keeps FFmpeg's output in a queue and returns exactly the
packet's duration, as libopus does: the first narrowband packet starts
with 24 samples of silence and the held-back samples follow in the next
calls. The new test decodes three libopus 6 kb/s narrowband packets and
a wideband packet after them; it aborts on main.

The JpegDec structures were libScePngDec's under new names. OpenOrbis
jpeg.h and SharpProspero JpegDec.cs agree on a 12-byte create param, a
0x30-byte decode param with a coefficient buffer, decode mode and down
scale, and a 0x24-byte image info that reports the coefficient memory
size, the suitable CSC attribute and the output size.
Accept the CSC attributes 1 and 2 that SharpProspero passes, fill the
output size, component count, coefficient memory size and suitable
attribute, apply the requested alpha, and throw for decode modes other
than 0 and down scales other than 1.

sceNetCtlGetState reports IPOBTAINED from the host's addresses, but
sceNetCtlGetInfo returned NOT_CONNECTED for every code. It now answers
from the host interface that holds an IPv4 address, preferring the one
with the default route: its address, netmask, gateway, MTU and DNS
servers. The link is presented as wired, connected, configured by DHCP
and without a proxy, with the Ethernet address sceNetGetMacAddress
reports. A null info returns INVALID_ADDR and a code outside 1..21
INVALID_CODE; the Wi-Fi, DHCP host name, PPPoE and proxy server codes
throw.

sceCoredumpAttachUserFile (5nc2gdLNsok) and
sceCoredumpAttachMemoryRegionAsUserFile (MEJ7tc7ThwM) get the
signatures of Orbital's db_types.json (cc408367) and SharpProspero's
KernelSystem.cs (5dfdb4b0): (uint32_t userValue, const char* path) and
(uint32_t userValue, const void* mem, size_t size, const char* name).
The handler is never invoked here, so both return
SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER (0x81180003, shadPS4
coredump_error.h e0a46675) and attach nothing; a null path or name and
a null, empty or wrapping region throw because the order of the
console's checks is unknown.

PPSA99058 and PPSA99420 import sceKernelGetCpuTemperature and sceKernelGetSocSensorTemperature and stop at start-up on main. Read the host CPU/package, board and NVMe sensors (hwmon/thermal on Linux, the ACPI thermal zones and the storage temperature property on Windows) and report an unsupported sensor with EINVAL.
2 Ship 2 Harkinian (PPSA99621) imports fchmodat through std::filesystem::permissions and stops at start-up on main. Resolve AT_FDCWD and absolute paths as usual and join other relative paths to the directory descriptor like openat, accept 0 and AT_SYMLINK_NOFOLLOW, and mask the mode to 07777.
TraceImport_nid_no_patch wraps a function of a library named in
APS5_TRACE_CALLS in a thunk that records the import, the thread and
the caller in a ring and counts the call, then jumps to the function.
One target keeps one thunk, so function pointers compare equal. The
crash and abort reports print the last 64 calls and the 32 most called
imports. Nothing calls TraceImport_nid_no_patch yet.

Porpoise (PPSA99764) stops on its weak chroot import (#3632, #4497).
Run 5 on main c2565f014, and again on a copy of that runtime:
FAIL: unresolved ELF import AKknh8Cx-V8 from libkernel_sys.prx
Its only call is in put_root_back (src/porpoise_jailbreak.cpp,
elripalda/Porpoise-Dolphin-Emulator-for-PS5 2ed1ab5a06995aa1): after a
jailbreak daemon has made the console's root its root and /app0 is
gone, it calls fchdir on the descriptor of "/" it opened at start, then
chroot("."), and checks the result. So it only ever puts back the root
it started in, and it does not use paths under any other root.
On top of the lookup errors of the previous commit, chroot now follows
FreeBSD 11.4 sys_chroot and pwd_chroot (8c639945, vfs_syscalls.c and
kern_descrip.c) for that case: a directory that is the guest root
("/", "/..", "." after fchdir to "/") succeeds without a change, since
fd_rdir would be set to the vnode it already is. The guest is taken
never to have changed its root, so with chroot_allow_open_directories 1
an open directory does not give EPERM. ENAMETOOLONG is added as in
pathconf, and a ".." through a file reports ENOTDIR instead of
escaping as a filesystem_error. Any other directory still throws: the
resolver's root and mount aliases are fixed, and no title is known that
needs a real new root.

Porpoise (PPSA99764) imports chroot (AKknh8Cx-V8) from
libkernel_sys.prx, not libkernel.prx, one reference. Predicted stop
once pathconf, the pthread_attr calls and ftrylockfile ahead of it are
covered (not a run):
FAIL: unresolved ELF import AKknh8Cx-V8 from libkernel_sys.prx
The NID is computed with tools/nid_names.py and matches aerolib.
Follows FreeBSD 11.4 sys/kern/vfs_syscalls.c sys_chroot and change_dir
(8c639945a44588f6cfdddfb057bb5aad88735da0) for a root caller up to the
lookup: EFAULT for a null path, ENOENT for an empty or missing one,
ENOTDIR for a file or a path through a file. A directory that is found
throws with the path named: the resolver's root is fixed and the mount
aliases (/app0, /savedata0) are host paths that do not move with it,
so it cannot be re-based, and a real chroot is not modelled. Nothing
shows that Porpoise calls it.

The console's mouse reports relative motion, so the host cursor can never line
up with the cursor a title draws. While a title has a mouse open and the
window is focused the host cursor is hidden and captured, released on focus
loss or while the pad's mouse-to-stick toggle is on. Motion deltas are scaled
from the presented image's size in window units to the title's display
resolution with sub-pixel carry, so the title's cursor travels as far as the
host pointer would, on scaled desktops and letterboxed windows alike.

ioctl() on a file, directory, pipe or character device threw "request
0x20006601 ... is not implemented" for FIOCLEX, and the same for
FIONCLEX, although the close-on-exec flag they change is already kept
for these descriptors and reported by fcntl(F_GETFD).
FreeBSD 11.4 handles both requests in kern_ioctl() for every descriptor,
before the request reaches the file's own ioctl, by changing the flag
F_GETFD reads. sys/kern/sys_generic.c, kern_ioctl():
case FIONCLEX:
fdp->fd_ofiles[fd].fde_flags &= ~UF_EXCLOSE;
goto out;
case FIOCLEX:
fdp->fd_ofiles[fd].fde_flags |= UF_EXCLOSE;
goto out;
sys/kern/kern_descrip.c, kern_fcntl():
case F_GETFD:
...
td->td_retval[0] =
(fde->fde_flags & UF_EXCLOSE) ? FD_CLOEXEC : 0;
Both requests now set or clear that flag and return 0. libuv before 1.44
sets close-on-exec this way on FreeBSD (uv__cloexec_ioctl).

PS5MC (PPSA99420, Kodi 22) imports clock_settime (d7nUj1LOdDU) from
libkernel.prx, one reference, after sigwaitinfo in its import order.
Predicted stop once the imports ahead of it are covered (not a run):
FAIL: unresolved ELF import d7nUj1LOdDU from libkernel.prx
The NID is computed with tools/nid_names.py and matches aerolib.
Follows FreeBSD 11.4 sys/kern/kern_time.c sys_clock_settime and
kern_clock_settime (8c639945a44588f6cfdddfb057bb5aad88735da0) for a
root caller: EFAULT for a null time (copyin), EINVAL for any clock but
CLOCK_REALTIME and for a negative tv_sec or a tv_nsec outside 0 to
999999999. A valid CLOCK_REALTIME request throws with the requested
time named, since the host clock must not be set and no guest clock
offset is kept.

The Python in PS5MC (PPSA99420) reads sysconf(_SC_CLK_TCK) while

A flip packet now delivers the queue's end-of-pipe event 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 it presented one frame and then waited forever.

image_sample_d and image_sample_cd on a cube pass their gradients through the
same conversion as the face coordinates, which subtracts 1.0 to move AMD's
[1, 2] face range to [0, 1]. A gradient is a difference of coordinates, so the
bias turned a one-texel gradient into one of about -1 and the sample read the
smallest mip. Gradients now skip the bias.
agc_driver_image_sample_cube_derivatives samples every face of a 16x16 cube at
five levels through image_sample_d and checks the level and face it read.
TechnicalDebt records that the gradient handling follows Mesa and was not
measured on hardware.
XPSemu PPSA97358 imports both from libkernel.prx; with the imports ahead
of them covered, its predicted next stops (relink registry order, not an
observed run) are:
FAIL: unresolved ELF import KaK52lYTBIs from libkernel.prx (execv, 7 call sites)
FAIL: unresolved ELF import kdguLiAheLI from libkernel.prx (execve, 4 call sites)
Today the title stops earlier at the observed
FAIL: unresolved ELF import aRo9AhFUXcM from libkernel.prx (sigsetjmp, merged in #3486)
As for execvp (#2827), the process image cannot be replaced here, so both
throw with the execvp message pattern once FreeBSD 11's execve would start
loading the image (freebsd-src 8c639945, sys/kern/kern_exec.c
exec_copyin_args, do_execve, exec_check_permissions; lib/libc/gen/exec.c
execv passes environ). Before that they fail as FreeBSD does: EFAULT for a
null argument vector or path, ENOENT and ENOTDIR from the lookup as stat
reports it, EACCES for a path that is not a regular file. Paths of
PATH_MAX bytes or more and strings over ARG_MAX throw instead of guessing
the console's limits. The execv calls in XPSemu's sources run in a fork
child (net/tap.c), and its fork fails with ENOSYS (ZiZc3/XPSemu 8eec07b4,
ps5/compat/libc_missing.c, ps5/build-title.sh --defsym).
NIDs computed with tools/nid_names.py and confirmed in aerolib.

(cherry picked from commit 57f0fa37132bc6c78bc02282044a00e2db859484)
getsockopt and setsockopt on a libkernel socket knew four SOL_SOCKET options
(SO_REUSEADDR, SO_BROADCAST, SO_SNDBUF, SO_RCVBUF) and failed every other
one with ENOPROTOOPT. The Mound's EOS SDK reads SO_ERROR on two of its
sockets after a connect, which therefore always failed.
The SOL_SOCKET options now follow FreeBSD 11.4 sosetopt and sogetopt:
- SO_ERROR returns the pending error of the socket as a FreeBSD errno and
reports it once (Winsock does not clear it on read, so the library does).
- SO_TYPE, SO_ACCEPTCONN, SO_KEEPALIVE, SO_DONTROUTE, SO_OOBINLINE and
SO_LINGER are read from and set on the host socket; the boolean options
read back as their own bit, as FreeBSD returns so_options & option.
- SO_DEBUG, SO_USELOOPBACK, SO_REUSEPORT, SO_TIMESTAMP and SO_NOSIGPIPE stay
ENOPROTOOPT until a title needs one.
- A value is read from its first int and fails with EINVAL when shorter, a
getsockopt buffer is filled up to its length (sooptcopyin, sooptcopyout),
SO_SNDBUF and SO_RCVBUF below 1 fail with EINVAL, and SO_LINGER outside
0..65535 seconds fails with EDOM.
A connect on a non-blocking socket now fails with EINPROGRESS on Windows too
(it was EWOULDBLOCK, which a title waiting for the connection does not
expect).

Palworld (PPSA23126, #2648) stops at start-up on the export, imported by
its bundled libdiscord_partner_sdk.prx:
FAIL: unresolved ELF import oiOi7vgPfAY from libSceAudioOut.prx
PPSA28416 imports it from its bundled party-ps5-shipping.prx as well. The
call itself has not been observed yet.
SharpProspero (5dfdb4b0, Interop/Audio/AudioOut2.cs:460-464) declares
`int sceAudioOut2EnableChat()`, "Allows chat audio alongside the
application's own", and the ps5-payload-dev SDK stub (f5d40f02,
sce_stubs/libSceAudioOut.c:62) exports it as well. There is no context or
handle to validate. The host mixes no chat audio and AudioOut2 has no chat
port, so the call records that chat audio is allowed (traced once with
APS5_TRACE_AUDIOOUT2) and returns 0. Whether the console fails it without
a chat session or when repeated is recorded in technical debt, and the
PPSA28416 "signature unknown" entry is dropped.
NID oiOi7vgPfAY matches tools/nid_names.py and the shadPS4 aerolib list.
