The IME panel cannot be open while sceImeOpen is unimplemented, so the
query returns SCE_IME_ERROR_NOT_OPENED and leaves the output untouched,
like sceImeSetCaret, sceImeSetText and sceImeSetTextGeometry. As with
sceImeSetCaret, the closed panel is reported before a null output.

shadPS4 returns success for an object id that was never reserved and the invalid-object error only for a released one; this library returns the error for both.

Both exports are imported by titles that link libSceAudio3d; without them the loader fails with an unresolved import before the title runs. Following the offline model, object attributes are validated but produce no audio and PortFlush drops the frames queued by sceAudio3dPortAdvance.
Pan follows the PS4 firmware 11.00 libSceNgs2.sprx: the speaker layout
from the init angles, then each param's angle and distance into a
volume matrix for the voice. Every param is checked before anything is
written, and angles too large to wrap throw. The pan functions are
exported from the existing Voice.cpp export block.

C17 has no binary prefix: with base 0 or 2, strtol("0b101", &end, base)
reads the subject "0", returns 0 and leaves end at the 'b'. With glibc
2.38 or later, g++ (which defines _GNU_SOURCE) binds std::strtoll,
strtoull, strtoul, strtoimax and strtoumax to the C23 __isoc23_*
functions, which accept 0b/0B: the Linux exports returned 5 and
consumed the whole string. The Windows UCRT already follows C17, so the
same guest call gave different results on the two hosts.
strtol, strtoul, strtoll, strtoull, _Stoull, strtoimax, strtoumax and
_Stoul now return 0 with the end pointer after the '0' when, after
white space and an optional sign, the text starts with 0b or 0B and a
binary digit, in base 0 or 2. Everything else still goes to the host
function. The scanf family's %i has the same glibc behaviour; it is
recorded in TechnicalDebt.

A port without a matrix sent source channel n to destination channel n, so a
mono voice reached only the left channel of a stereo mix. The PS4 firmware
11.00 libSceNgs2.sprx mixes such ports, and ports whose matrix levels were
never set, through a fixed channel map instead: mono reaches both stereo
channels at -3 dB and the centre of 5.1 and 7.1, stereo folds to mono at
-3 dB per side, and wider sources fold down with 0.5 and -3 dB gains. The map
was measured for every source width into 1, 2, 6 and 8 channels.

PPSA22520 routes its title music through port matrix 0 without setting the
matrix levels, so the music rendered silent. A matrix without levels now
mixes like a port without a matrix, source channel n to destination channel
n. The console's initial levels are unknown; the assumption is recorded in
TechnicalDebt.

FreeBSD vsyslog logs the complaint with LOG_ERR|LOG_CONS|LOG_PERROR|LOG_PID passed as the priority (0x23), not LOG_ERR.
Co-Authored-By: Claude <noreply@anthropic.com>
ps5-opengl (PPSA99005) and ProsperoRadio (PPSA99001) import syslog
from libSceLibcInternal. Messages go to stderr with the priority, and
the format follows FreeBSD's vsyslog: %m expansion, masking of unknown
priority bits, LOG_USER as the default facility, errno preserved.

A title's descriptors are taken as never being terminals: a file or
pipe gets ENOTTY with the termios untouched, a socket gets what its
protocol answers a termios ioctl on FreeBSD (EADDRNOTAVAIL for AF_INET,
EOPNOTSUPP otherwise), and a closed or invalid descriptor EBADF.
tcsetattr gives EINVAL for an action other than TCSANOW, TCSADRAIN or
TCSAFLUSH, with or without TCSASOFT, before anything else, and EFAULT
for a null termios before the descriptor is checked; with TCSASOFT a
null termios throws, where FreeBSD's libc faults copying it. What the
console gives a title as descriptors 0 to 2 is unknown, as recorded in
TechnicalDebt.

LibwuIonIBw registers video out event id 16, which the host never triggers because its VRR state does not change; kP2L8t3j-aM returns 0 without effect.
Keeps this branch's CONTEXT_FULL | CONTEXT_SEGMENTS read, context-first
order and bounded retry in RaiseOn, and adds #1478's ymm save fields to
both deliveries. The test keeps both phase sets; the vectors phase runs
after the continuing, selfing and looping phases and counts their
deliveries. The TechnicalDebt entry about ymm upper halves is dropped,
since #1478 preserves them.

Titles that link the release module libScePsml.prx failed to start
because no host library had that name; PPSA25344 links it. libScePsml
and libScePsml_debug are now built from the same source.
scePsmlMfsrGetDispatchMfsrPacket1000, which PPSA25344 imports, is
added without an implementation.

The guest process is assumed to run as root. Under FreeBSD's
sys_seteuid and sys_setegid, id 0 is then accepted without a privilege
check and changes no credential, so both return 0. Any other id would
change the effective credential, which is not modelled, and throws.
Part of #1578.
sceNpEAAccessInitialize and sceNpEAAccessTerminate resolve the NIDs
7CxI50-xlCk and pMxXhNozUX8, which shadPS4 names in np_partner.cpp. The
stubs still throw; only the names and no-argument signatures change.
Use INFINITY and NAN from <cmath> instead of a new <limits> include, and
list the TechnicalDebt entry beside the other NGS2 voice entries, so the
change merges cleanly with the pan, channel map and reverb changes.

The template allocated a fixed 4 KiB of LDS, so kernels with immediate
offsets past it could not run. --lds (Python lds) sets the group segment
size in bytes, up to 64 KiB, with 4096 as the default.

A reverb_size other than the default was accepted and ignored, and below
about 7.5 kHz an allpass length went negative and wrapped to a 16 GB buffer.

Parse legacy decimal, octal and hexadecimal forms before host lookup. Preserve FreeBSD shorthand, whitespace and 64-bit accumulation, clear the SDK resolver error on numeric success, and add regression coverage.
winpthreads initializes a PTHREAD_RWLOCK_INITIALIZER lock on its first
use and fails a concurrent first lock with EINVAL. std::shared_timed_mutex
ignores that result in release builds, so two guest threads could both
hold a fresh guest rwlock.
Lock and unlock the mutex once when the guest rwlock is created, before
another thread can reach it, and record the remaining host exposure.

libSceVdecsw is the software H.264 decoder interface PPSA05684 uses for
its movies. Decoder creation, compute queues, memory queries, decode
input and output, AVC picture info, reset and finalize are implemented
with the layouts of shadPS4's vdecsw.h, checked against the title's
movie decoder, and decode through libSceVideodec2. The H.264 stream the
Videodec2 test uses moves to a shared fixture, and a guest test decodes
it through Vdecsw.
Uncharted: Legacy of Thieves Collection (PPSA05684) plays its movies through libSceVdecsw and stopped at sceVdecswQueryComputeMemoryInfo.
