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 <[email protected]>
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.
llvmpipe builds the high dword of the shader clock with a left shift by
32 (emit_clock in Mesa's lp_bld_nir_soa.c), so it is always 0 and
s_memtime and s_memrealtime wrap every 2^32 ns. A pass of
agc_driver_shader_clock whose two reads straddle a wrap failed with
"memtime: lane N went back from 4294921902 to 3823"; dispatching right
before the boundary fails every lane of that pass.
On llvmpipe compare the low dwords modulo 2^32, which stays correct if
Mesa fixes the shift. Other devices keep the 64-bit comparison.

PS5 titles pass a 0x230-byte SceAvPlayerInitDataEx: auto start is the
byte after debug_level at 0x74, nine 0x30-byte thread parameter blocks
fill 0x78-0x228 and the output video frame buffer count is at 0x228.
sceAvPlayerInitEx read both fields at their PS4 offsets: auto start at
0xa8 is the video decoder thread priority and the buffer count at 0xa4
lies in the audio decoder block. PPSA25063 (Poppy Playtime: Chapter 4)
sets every thread priority to 700, so its intro video started on its
own and stopped at once; it writes auto start 0 and starts playback
itself.
With this_size 0x230 or more both fields are read at the PS5 offsets;
smaller structures are read as before. The layout follows KytyPS5,
prosper, SharpProspero and sharpemu and is recorded in TechnicalDebt.
guest_avplayer builds a 0x230-byte structure with auto start 0 and
nonzero thread parameters, then with auto start 1, and checks when
playback starts and how many video buffers are allocated.

sceVideoOutAddPreVblankStartEvent threw "physical pre-vblank timing is
not implemented", so titles that pace on it stopped at startup. It now
registers the event like the vblank event does, and each emulated vblank
tick triggers the pre-vblank start events just before the vblank events,
with the pre-vblank count as data. The console's lead time is unknown.
