On a PS5 (firmware 13.60) a null name returns INVALID_ARGUMENT first,
then a user id the console does not know returns 0x80960105 whatever
the buffer, and a buffer shorter than 17 bytes is zeroed before
BUFFER_TOO_SHORT is returned. Here an unknown user returned
INVALID_ARGUMENT and a short buffer was left untouched.

With SO_RCVTIMEO set, Winsock fails a receive that waits that long with
WSAETIMEDOUT, which native_error turned into ETIMEDOUT (60). sceNetRecv,
sceNetRecvfrom and sceNetRecvmsg on a datagram socket therefore failed
with 0x8041013C on Windows, where FreeBSD's sbwait returns EWOULDBLOCK
(35) to soreceive, Linux returns EAGAIN, and POSIX (XSH 2.10.16)
requires EAGAIN or EWOULDBLOCK when no data was received.
A datagram socket has no connection that can time out, so WSAETIMEDOUT
there only means that the receive timeout the guest set has expired:
report EAGAIN. Stream sockets keep ETIMEDOUT, since Winsock leaves a
connection in an indeterminate state after a timeout; TechnicalDebt
records that gap and the one for SO_SNDTIMEO.
On a PS5 (firmware 13.60) scePthreadAttrSetsolosched and
pthread_attr_setsolosched_np accept only 0 and 16; every other value
returns ENOTSUP and keeps the stored one. The SCE set and get calls
return EINVAL for a null or uninitialized attribute instead of throwing.

fopen opened its stream with _wfopen, which shares read and write
access but not delete access. While the guest held a stream open,
rename of its file failed with EIO and remove with EBUSY. POSIX rename
and remove work on open files, as on Linux and FreeBSD, and since
#3677 the descriptors sceKernelOpen returns share delete access.
fopen now creates the handle with CreateFileW sharing read, write and
delete, with the access and creation disposition of the mode, and
wraps it with _open_osfhandle and _wfdopen, keeping append mode. A
failed CreateFileW sets errno through the error mapping #3677 added to
libkernel's NativeOpen, which moves to libc as
WindowsOpenError_nid_no_patch so that both use it. freopen still
reopens through _wfreopen; TechnicalDebt records it.
With the f32 denormal field of FLOAT_MODE set to keep, v_cmp_X_f32 and
v_cmpx_X_f32 read a denormal operand as zero: NVIDIA, RADV and lavapipe
all flush denormals in their float compares. Compare the operands as
sign-magnitude integers instead, with NaN handled apart. Compares with
flushed denormals are unchanged. This matches RDNA2 (gfx1036) on 256
operand pairs per opcode, with f32 denormals kept and flushed.

On a PS5 (firmware 13.60) destroying a rwlock returns 0 even while it
is held, and leaves 1 in the handle; every later call on that handle
returns EINVAL until it is initialized again. A zero handle is
initialized on first use by the scePthreadRwlock calls too. Here a held
rwlock returned EBUSY, a destroyed handle became null and was silently
re-created by the next POSIX call, and the scePthreadRwlock calls threw
on a zero handle.

A playing sampler voice whose waveform still accepts blocks (CONTINUE)
reported only INUSE|PLAYING after it had played every queued block, so
a title that waits for EMPTY before it reuses the voice never did.
PPSA18391 (engine: Clickteam Fusion) reads state_flags & 0x22 != 2 from
sceNgs2VoiceGetState as the end of a sound; each of its sound effects
played once and never again.
The voice now also reports EMPTY (0x20) in that state and keeps
playing, so blocks added later still play. A waveform that was closed
without CONTINUE does not report it.
Resident Evil 4 (PPSA07411, #2776) and PRAGMATA (PPSA02530, #3043) stop

Deathloop, Minecraft Legends and Cyberpunk import the base-object
constructor InitParameter2::InitParameter2(), InitParameterRtti2::
setAllocatorRtti and InitParameterRtti::InitParameterRtti(AllocParamRtti*,
void*, unsigned long), which were NotImplemented stubs.
InitParameter2 is the 40-byte object of SharpEmu and KytyPS5: the
allocator, its user data, the file buffer size and the 32-bit special
float format type at 0x18. Both constructors zero it, setAllocatorRtti
writes the allocation parameters and user data where setAllocator writes
the allocator, and setSpecialFloatFormatType stores the type.
InitParameterRtti's constructor writes its three arguments to the first
24 bytes. The NID WVZBP4IyM+E recomputes from the mangled name and is in
the aerolib database. The enum's values are unknown, so no value is
rejected; the inferred layouts are recorded in TechnicalDebt.

The third argument is a relative timeout in microseconds, not a
struct timespec. FreeBSD 11.4 libthr (8c639945a44588f6cfdddfb057bb5aad88735da0)

NID and the same function for scePthreadCondTimedwait (BmMjYxmew1w), whose
microsecond argument this repository already implements. The width follows
the SCE twin's 32-bit SceKernelUseconds, as sem_reltimedwait_np does, not

Exports pause (EDyhWelj7UY), sigwait (mrbHXqK8wkg) and sigwaitinfo
(Uq5BGthgbl4) from libkernel. NIDs computed with tools/nid_names.py and
matched in aerolib; ps5-payload-dev/sdk f5d40f02 sce_stubs/libkernel.c
places all three in libkernel.
They throw like the merged sigtimedwait (#3430), with the same message
pattern: "sigwait: waiting for a pending signal", "sigwaitinfo: waiting
for a pending signal" and "pause: waiting for a delivered signal". In
FreeBSD 11.4 (8c639945) sigwaitinfo is kern_sigtimedwait without a
timeout (sys/kern/kern_sig.c:1212), sigwait is the same wait returning
the error number (kern_sig.c:1150, lib/libthr/thread/thr_sig.c:676-728)
and pause is sigsuspend of the current mask (lib/libc/gen/pause.c:46-56).
AnyPS5 never leaves a guest signal pending (blocked signals are dropped
in Dispatch, raise delivers at once), so there is nothing to take, and
raise, kill and pthread_kill run a handler only on the calling thread,
so nothing can end a pause.
Titles (predicted stops, registry order; not observed runs):

NativeError listed 17 Winsock and 17 POSIX errors and turned every other
one into EIO. A second connect while the first is pending (WSAEALREADY,
EALREADY) and an option the host rejects (WSAENOPROTOOPT, ENOPROTOOPT)
reached the guest as EIO; on Linux a nonblocking connect (EINPROGRESS),
a send with no destination (EDESTADDRREQ), ENOTSOCK, EAFNOSUPPORT,
EOPNOTSUPP and others did too.
The translation moves to SocketError.hpp and covers the socket errors of
both hosts by name, with the FreeBSD 11 numbers. WSAESHUTDOWN stays EPIPE
as before. socketpair's own table is gone, as NativeError covers it.

The guest-access guard covers CB bytes times samples (the single-sample layout size alone missed the later sample planes' tile padding), with a test row in that padding. Remove two TechnicalDebt lines duplicated by the rebase, document the guard bound and the unevicted targets, and add the multisampled targets to ARCHITECTURE.md.
The duplicate ColorTarget::cmaskAddress, decode and size helper are gone: multisampled targets
use main's cmaskAddress/cmaskBytes (whole metablocks). Single-sample targets keep main's rule
(CMASK under FAST_CLEAR); a multisampled one takes it under FAST_CLEAR or COMPRESSION. A zero
fill of the whole CMASK clears at the next use, 0xFFFFFFFF marks it expanded, any other or
partial fill refuses the next use; eliminate/DCC passes over a multisampled target and a CB
resolve into a fast-clear destination are refused. The draw key adds CMASK_BASE_EXT (0x398),
which main decodes but did not key.

A descriptor replaced before the shared-memory path probe can otherwise
bypass the pinned-object identity check through native fallback. Compare
the negative probe's current file identity to the initial snapshot and
reject a mismatch. Exercise the earlier window with an ordinary file for
all six descriptor operations.
Confidence: high
Scope-risk: narrow
Tested: 18 Linux runtime tests with zero skips; 18 deterministic reuse scenarios; affected three patched modules; standalone ASan/UBSan; Clang analyzer; conventions and diff checks
Not-tested: Full project build/suite, Windows runtime, console hardware and titles
Directive: Identity checks do not synchronize the entire descriptor table or identify separate opens of the same inode
Keep guest creation-mask state in libc behind C-linkage helpers so NID
patching preserves the shared exports. Reject a pinned descriptor whose
file identity differs from the snapshot taken before classification.
Exercise close and reuse from another thread at both acquisition windows
for writes, resize and seek, and create temporary ordinary-file fixtures
so runtime tests work without the source tree.

Not-tested: Full project build and library set, Windows runtime, console hardware and titles
Directive: Device/inode validation establishes file identity, not open-file-description identity
Pin the descriptor before mmap validation so guest descriptor reuse cannot
redirect the eventual mapping. Apply the canonical guest creation mask when
creating named objects, distinguishing new objects before setting permissions
without changing the host process umask. Add regressions that reproduce both
failures and document the remaining host requirements.

sceUserServiceGetAgeLevel reported 0. On a PS5 (firmware 13.60) the
value is the age of the user's parental restriction (0, 7, 12 and 15

0. A user who is not logged in returns 0x80960009 (not logged in) with or

A FLAT_SHADE input without pass-through that a pixel shader reads
through v_interp_mov_f32 P10 became an explicit per-vertex input and
read vertex 1 minus vertex 0. With the last provoking vertex the
pipeline then threw ("last provoking vertex with explicit per-vertex
flat interpolation is unsupported"), which stopped all three
ps5-opengl titles in the catalog.
ps5-opengl reads every flat input through P10 when GL's last-vertex
convention is in effect, and its driver passes the GL 4.6 CTS on a PS5
(#1413). Such a read now returns the provoking vertex's value, as P0
does, and only a P20 read keeps a flat input per vertex. The lane was
not measured on the console itself, so FragmentParameter records it
and a pipeline using the first provoking vertex throws.

`kern_setgroups` does (`NGROUPS_MAX` 1023, an empty list leaves the
effective group as the only entry, a first entry other than 0 throws) and
the new `getgroups` reports it. `guest_credentials` covers the accepted

M0 is unsigned, so an index at or past the window reads v0 and drops its
write, v_swaprel_b32 writes neither side when either is out of range, and
the window array starts zeroed like unwritten SSA registers; the window
load counts as a lane source so a wave64 program's second half keeps its
own registers. agc_driver_relative_indexing runs in wave32 and wave64 and
pins the rows measured on gfx1035 in the review of #3856, and the
TechnicalDebt entry states the measured behaviour, the window's end at the
last named register and the sizes.

PPSA28416 calls it on its existing save at boot (after sceSaveDataDirNameSearch finds it) and aborted on the missing implementation. The call takes one parameter block: user id at +0, the directory name pointer at +8. Host saves have no size limit, so the conversion completes at once: an existing save returns OK, a missing one NOT_FOUND, an invalid name PARAMETER. The title polls sceSaveDataGetEventResult once afterwards and continues on 'no event'.
The search returned saves in host directory order and ignored the condition's key and order. A title that asks for the newest save first (modification time, descending) got whichever directory the host listed first: the alphabetically first on NTFS, an arbitrary one on Linux. Sort by directory name, user parameter or modification time, reverse for a descending order, and reject unknown keys and orders with the parameter error, as shadPS4 does.
PPSA06888 stops on main at start-up because its bundled
Media/Plugins/SceRudp.prx imports sceRudpEnableInternalIOThread2,
sceRudpGetOption and sceRudpGetRemoteInfo, which no library exports.
The signatures are unknown, so they are declared without parameters and
throw. The title does not call them during start-up.

A rect-list draw whose count is not a multiple of 3 threw "incomplete rect-list

scePadOpen returned the standard pad's handle for a special port
(type 2) as well, and scePadGetHandle found it there. Both ports then
read the one input queue, so a press queued between two frames could be
drained by the special port's read and never reach the standard port.
PPSA16827 (Harmony's Odyssey) opens both ports for the initial user and
reads both every frame, also polling controller information and device
class data for the special one.
Special ports now return DEVICE_NOT_CONNECTED (0x80920007) from
scePadOpen, as scePadOpenExt already does because the host has no
special controller, and scePadGetHandle has no handle for them.
TechnicalDebt's scePadOpenExt entry now covers both calls.
guest_pad opens a special port before and after the standard one and
expects DEVICE_NOT_CONNECTED, and DEVICE_NO_HANDLE from scePadGetHandle
for the special port while the standard handle stays valid. It fails on
main.
PPSA16827 over 130 s of its title screen: 6812 scePadRead, 3408
scePadGetControllerInformation and 3406 scePadDeviceClassParseData calls
before, two reads of the same queue per frame; 2702 reads, one
information call and no parse calls after.
Elden Ring Nightreign (PPSA25380) imports the function, which no library
exported, so the title failed to load. The option is ORed into the buffer
attribute and a null attribute throws. Options other than 0 and 8 still
throw when the buffers are registered.
`v_movrels_b32`, `v_movreld_b32`, `v_movrelsd_b32`, `v_movrelsd_2_b32`
and `v_swaprel_b32` lowered to a compare-and-select chain over every
register from the base to the program's last allocated register, so a
program addressing 154 registers 104 times turned 3176 ISA words into
649,515 SPIR-V words that Intel's compiler did not finish. The registers
from the lowest relative base up now live in a function-scope array per
invocation (`LoadVectorWindow`/`StoreVectorWindow`), so an indexed access
is one load or store; plain accesses to those registers go through the
same array, DPP-modified relative writes keep their `DppUpdateU32` merge,
an index past the window reads 0 and drops its write, and programs
without relative addressing are unchanged. The same program recompiles
to 392,333 words with 4,992 selects instead of 32,383.

sceKernelGetOperationMode returned 0 for both values, which were

Hollow Knight Silksong (PPSA12544) imports libSceAgc NID vieBRwlh1Lw
(#699). Its name is unknown: it is not in aerolib, and the
sceAgcUpdateInterpolantMapping label other projects give it hashes to
SbuY2jN+axQ.
OpenAGC (src/game_compat.c at 3c7e807, sceAgcUnknownVieBRwlh1Lw) reads
it from FW 11.60 as the dbOlWdppb4o transform with the same (regs, gs,
ps) arguments, without the identity tail: it writes one register per
pixel shader input, none for a pixel shader without inputs, and rejects
a null pixel shader. It now shares the dbOlWdppb4o path and throws for
the rejected arguments.
For is_f16 1 and 3 inputs whose default_value and default_value_hi
differ, OpenAGC takes DEFAULT_VAL from default_value_hi, while KytyPS5,
sharpemu and dbOlWdppb4o here take it from default_value; these inputs
throw. On every other input the dbOlWdppb4o values equal OpenAGC's.

agc_driver_f32_denormal_flush fails on RADV RENOIR (Mesa 26.2.4):
lane 20 no float mode v_fma_f32 v14, v4, v5, v6 is 0x00800000, expected 0x00ffffff
The driver lowers Fma to a multiply and an add: the compiled shader has
v_mad_f32 and no v_fma_f32. The product 0x1fffffff * 0x1fffffff is below
2^-126 and is flushed before 0x00800000 is added. Lane 20 is the only
row with a tiny product and a non-zero addend. v_fma_f32 and v_fmac_f32
fail on it in all three float modes; every other check passes.
When both return that sum, the two values are not checked. FmaRounding
already leaves out its fused forms on a device that splits fma.
PPSA30601 (Resonance: A Plague Tale Legacy) 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 a TechnicalDebt entry.

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.

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.

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.
