Surround Sound Studio (PPSA99051), catalog build on main a11c8f7f with
the flat-interpolation fix, stops 16 s in, before its first frame
(orishamir, #3581 comment 6109839314):
sceAudioOutSysGetHdmiMonitorInfo not implemented
The call takes (type, out, size); out must be non-null, size exactly
0x180 and type 1 (HDMI) or 0x10 (sainsaji/PS5-Audio-Passthrough-Research
c3be9c2a, docs/FINDINGS.md section 3 and AGENTS.md:25, firmware 12.70).
Titles read the monitor name at +0x0B, the descriptor count at +0x94 and
8-byte descriptors from +0x98 (same, FINDINGS.md hardware log item 1 and
sample-app/src/platform/ps5/bitstream_out.cpp:92-128).
Audio reaches the host through SDL as PCM and there is no EDID, so type 1
with a 0x180-byte buffer reports a sink without a name or descriptors:
the buffer is zeroed and 0 is returned. Surround Sound Studio's
Passthrough page then lists no formats; EVO Player's code treats an empty
list like a negative return. A null buffer returns 0x80260004, as the
other AudioOut calls do. Type 0x10, other types and other sizes throw:
their results and error codes are not known.

PPSA07411 (Resident Evil 4) fails to load without these imports that no library exports. Their signatures are unknown, so they are declared without parameters and throw until they are implemented. Adds one test and a TechnicalDebt entry.

Dying Light 2 (PPSA02262) imports sceKernelAioSetParam (9WK-vhNXimw) from
its eboot. In #1794 tv7 reported on main b5f5362d3 + #2129 (2026-10-10):
FAIL: unresolved ELF import -q-vbO859Tw from libSceVideoOut.prx
with "12 other imports are still unresolved on `main`. In the eboot,
`-q-vbO859Tw`, `GTfJ64qFCPw`, `vwtVpHQKelI` (no known names),
`sceKernelAioSetParam` and `sceNpWebApi2GetMemoryPoolStats`." The import
is observed; its position in the loader queue after the nameless NIDs is
predicted.
The function fills one SceKernelAioSchedulingParam (five 4-byte fields,
20 bytes): Orbital cc408367 tools/ida/db_types.json:1103, SharpProspero
5dfdb4b0 Interop/Kernel/KernelAio.cs ("Sets every field of param at
once") and ampr_emu cfa85df3 ps5/include/sce/_fs.h agree on
(param, schedulingWindowSize, delayedCountLimit, enableSplit, splitSize,
splitChunkSize). No source gives an error code, so a null struct and
values outside SharpProspero's maximums (window and delayed count 0..128,
split flag 0 or 1, sizes up to 0x1000000) throw. The engine does not use
the settings, as sceKernelAioInitializeImpl ignores its struct; this is
recorded in TechnicalDebt.

(cherry picked from commit e45a2b950afe594212db2764529ccae32f84be8c)
sceKernelAvailableFlexibleMemorySize and the flexible maps counted only
explicit flexible mappings, so the full 448 MiB was reported while the
title's executable and modules were loaded. A title that derives its code
and data size from the budget minus the available size got an unsigned
underflow.
The segments of the main executable and of every .guest.prx module that
the title's ELF gives permissions now count, rounded to 16 KiB pages, as
shadPS4 maps every non-system module segment as flexible memory. The
relinker's own blocks and the host system libraries do not count. The
charge ends when a module is unloaded.

Deathloop (PPSA01670) imports sceHttpAbortWaitRequest; Planet Coaster
(PPSA01736) and Palworld import sceHttpWaitRequest.
Epoll handles are kept in a registry with an abort flag, a destroyed flag
and a condition variable. A wait with a negative timeout blocks until
sceHttpAbortWaitRequest, sceHttpDestroyEpoll or the sceHttpTerm of the
last context wakes it; a bounded wait still returns 0 events. An abort
stays set and makes every later wait return SCE_HTTP_ERROR_ABORTED
(0x80431080); a wait woken by destroy or term returns 0 events.
sceHttpDestroyEpoll no longer frees a handle a waiter is blocked on.
sceHttpInit registers its context, and the epoll calls and sceHttpTerm
return BEFORE_INIT without a live context and INVALID_ID for an unknown
context or handle.

The call was an unimplemented stub. It now writes syllable state 0 and
returns OK for every character outside the Thai block, where a PS4
firmware 11.00 libSceFont measures 1, 3 or 4; Thai characters throw as
not implemented. A null character or result returns
SCE_FONT_ERROR_INVALID_PARAMETER, and a null character writes 0 to a
non-null result, as measured. The signature follows SharpProspero.

The second argument is an out pointer to the writing's letter step, as
KytyPS5 and the SharpProspero bindings declare it. It was filled as a
letter step struct, which wrote 64 bytes over the caller's 8-byte
pointer. The letter step now lives in the writing and the call stores
its address, or null when there is no current step.

Both open the same SDL capture port as sceAudioInOpen, so Input,
GetSilentState and Close work on their handles. HqOpen accepts only a
128-sample grain at 48 kHz (SharpProspero, KytyPS5); AsyncOpen returns
INVALID_SIZE above 384 samples (SharpProspero). Values the sources
disagree on throw. Format 0x10 still throws: only KytyPS5 accepts it.
Imported by FMOD-based titles, The Smurfs Dreams (PPSA21607) and Astro
Bot (PPSA21564); Ghost of Yotei (PPSA26344) calls sceAudioInOpen.

On the AMD Windows driver 32.0.13058.8001 (Radeon 860M), a NaN compared
less than +infinity, or +infinity greater than a NaN, gives 1 when the
infinity reaches the shader as a constant, as in
agc_driver_f32_compare_constant's register operand case (#3536). The
same driver returns 1 for a NaN in an ordered not-equal (#825), which is
presumably what its compiler turns these compares into. FPOrdLessThan32
and FPOrdGreaterThan32 now AND their result with the integer NaN check
FPOrdNotEqual32 already uses, which gives the same result for every
input.

RADV (Mesa 26.2.4, GFX12) updates the user SGPR count and draw-id flag
it uses for a mesh dispatch only when the bound mesh shader has the
grid-size/draw-id slot. A mesh shader reading neither NumWorkgroups nor
DrawIndex keeps the previous vertex pipeline's values: the dispatch
opens a 3-register SET_SH_REG, writes one value, and the CP parses the
following DISPATCH_MESH_DIRECT as register data. The gfx ring then
times out and the GPU is reset with VRAM lost.
Kena: Bridge of Spirits (PPSA01802) hits this on its layered volume
draws, which interleave with vertex draws in one command buffer.
Confirmed with RADV_DEBUG=hang (the dispatch header shows up as
SPI_SHADER_USER_DATA_GS_4) and the CP header history in the amdgpu
devcoredump.
Every mesh shader now loads NumWorkgroups.x and sets zero vertices
when it is 0, which no dispatch produces, so RADV gives it the
grid-size slot and writes as many values as it announces.

PPSA15246 (Teardown) imports both from the module-named libSceCesCs-module and
stops at the loader without them. Cp1251 joins Cp1252 in sceCesSbcToUtf8 and
sceCesUtf8ToSbc; the context initializer succeeds without storing anything
because its layout is unknown (listed in TechnicalDebt.md).

winpthreads initializes a statically initialized rwlock on its first
lock and fails a concurrent first lock with EINVAL, which
std::shared_mutex ignores, so two threads can hold the lock at once.
The source, binding plan and specialized module caches take their
first locks from several threads, so their mutexes now take and
release the lock in their constructor, as guest rwlocks do.
The GuestWriteWatch mutex the technical debt entry also named is in
the Linux-only watch, so it is not affected.
In #3338, Ratchet & Clank: Rift Apart (PPSA01474) hits a 36 GB / 5 s
memcpy stall at frame ~380 right after intro logos because the GPU
worker thread is blocked copying multi-gigabyte storage buffers on every
draw snapshot miss (specifically a 3.01 GiB streaming range
0x118f800000+0xbc200000 and a 232 MiB range 0x1171258040+0xe7fffc0
across 130,000 draws).
ShaderResources::PrepareDrawBindings now caps both per-allocation and
cumulative draw input buffer snapshot copies at 64 MiB by default,
overridable via APS5_DRAW_SNAPSHOT_MAX_MIB. Inputs exceeding the threshold
skip snapshotting and bind directly in place, preventing multi-gigabyte
memory copies while preserving standard small uniforms and draw arguments.
Budget allocation prioritises earlier descriptor bindings in deterministic
pipeline layout order.
Adds drawSnapshotCapTests in core/libs/prx/libSceAgcDriver/tests/Recorder.cpp
verifying individual and cumulative capping, cross-platform cache behavior on
watched and compared hosts, and direct observation of subsequent CPU writes
on in-place bound ranges exceeding the cap. Exercised via --draw-snapshot-cap-only
registered as agc_draw_snapshot_cap in libSceAgcDriver/CMakeLists.txt.
PPSA04540 (Rise of the Ronin) imports it. The characters the callback
returns are parsed as by the (text, size) overload.

CB_COLOR_INFO format 17 with UNORM and the standard component swap renders
into VK_FORMAT_A1R5G5B5_UNORM_PACK16, whose attachment and blend support
Vulkan requires. AMD keeps X in the low bits and Vulkan keeps R in the
high bits, so the exports are mapped with X and Z exchanged and the stored
bits follow the guest layout. PPSA06699 renders into this format.

Defer registered NGG workgroup preparation until routing is known. Share the routing decision with static ABI resolution and draws. Gate the wave64 fixture on supported mesh subgroups; retain device-independent routing coverage.
PS5MC (PPSA99420) stops at start-up on sendfile. It follows FreeBSD 11:
headers, the file range and trailers go to a connected stream socket, the
file offset does not move, a non-blocking socket fails with EAGAIN after
a partial send, and *sbytes reports what was sent. The checks and the
point where *sbytes is written follow kern_sendfile.c.
The guest formatter threw on %n$ and *m$, which FreeBSD's vfprintf and
glibc accept. It now reads the arguments a numbered format names into a
table first, with the types their conversions give them, and follows
FreeBSD's rules for unnumbered conversions and unnamed arguments.
FreeBSD's vfprintf takes ' as the thousands-grouping flag. The Windows
formatter threw on it as an unsupported conversion. The guest's setlocale
only accepts the C locale, which has no thousands separator, so the flag
changes nothing: it is dropped before the host's printf sees it, and the
host's locale cannot add separators.
EVO Player (PPSA99039), Jelly5 (PPSA99505), Emby5 (PPSA99515) and
Nuvio PS5 (PPSA99997) stop on main 0f863c10 with
what(): sceAgcCreatePrimState: invalid user configuration register offsets
All four build their shader headers by hand (EVO-PLAYER-PS5
evo_agc_shader_header.c, ported from ps5-xash3d-halflife) and store the
ge_user_vgpr_en special at 0x25c (GE_USER_VGPR1, value 0) instead of
0x262 (GE_USER_VGPR_EN), as analysed in #3457. They run on the console.
OpenAGC's reconstruction of the FW 5.50 sceAgcCreatePrimState
(src/game_compat.c at 3c7e8072) copies the four special register pairs
verbatim without checking their offsets; KytyPS5's offset checks
(src/libs/agc.cpp at 16a7fe68) are EXIT_NOT_IMPLEMENTED guards. The
special is now copied at the offset the header stores, not moved to
0x262; the driver reads neither register. GE_CNTL, VGT_SHADER_STAGES_EN
and a used VGT_GS_OUT_PRIM_TYPE are still required at their own
offsets because the driver reads them there, and the error now names
the special and the offset found.
With the change all four titles get past sceAgcCreatePrimState and stop
in the shader recompiler (GetImageResource dword 3 is not a valid
runtime value), as #3457 reported for EVO Player.

Porpoise PPSA99764 stops after pthread_attr_* (#3494) with the
predicted `FAIL: unresolved ELF import h05OHOMZNMw from
libSceLibcInternal.prx` (idx 311, call site 0x8EC37); RetroArch
PPSA99169 imports it at idx 448 (call site 0xA4A27). h05OHOMZNMw is
ftrylockfile by tools/nid_names.py and aerolib.csv (zecoxao/sce_symbols
2883963a); ps5-payload-dev/sdk f5d40f02 declares
`int ftrylockfile(FILE *)` in include/freebsd/stdio.h.
ftrylockfile tries the same host CRT stream lock that flockfile,
funlockfile and every locking host stdio call on the stream take, so
no second lock exists beside the one stdio uses. It returns 0 when the
lock is acquired or already owned by the caller (recursive, released by
as many funlockfile calls) and -1 when another thread holds it, as
FreeBSD 8c639945 lib/libc/stdio/_flock_stub.c:89-104 does. Linux calls
glibc ftrylockfile. UCRT has no try variant of _lock_file, so Windows
calls TryEnterCriticalSection on the CRITICAL_SECTION that _lock_file
enters (__crt_stdio_stream_data::_lock, ucrt/inc/corecrt_internal_stdio.h,
same layout in Windows SDK 10.0.19041, 10.0.22621 and 10.0.26100). A
null or closed stream throws. The UCRT layout dependency is recorded in
TechnicalDebt.
guest_standard_streams covers trylock on an unlocked stream, re-entry
by the owner, failure from another thread while held (also after one of
two unlocks and while another thread holds flockfile), stdio calls
from another thread blocking on the trylock-held lock, release order,
and null and closed streams.
