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
measured) and 0xFFFFFFFF without one, so 0 is a user restricted to age
0. A user who is not logged in returns 0x80960009 (not logged in) with or
without an output, before the null output check.

Two more agc_driver_relative_indexing rows read a register of the window
the program never wrote, directly and through v_movrels_b32, and expect 0,
which the zeroed window array gives like an unwritten SSA register did;
the TechnicalDebt entry says the console's value is undefined.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
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.

The f16 unary ops, v_frexp_mant_f16, v_frexp_exp_i16_f16, the norm
conversions and v_cvt_f32_f16 read denormal halves as they are and
rounded denormal results as they are, whatever the denormal field of
FLOAT_MODE says. On RDNA2 a clear bit 0 flushes a denormal half input
to its signed zero and a clear bit 1 flushes a denormal half result.
One shared rule now drives all of them, and v_ldexp_f16 uses it for its
input too.

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
primitive". Rect lists are drawn as patch lists of 3 control points, and Vulkan
generates floor(vertexCount/3) patches, so the draw now records as is and the
trailing 1 or 2 vertices are left out. Palworld (PPSA23126) draws 4 vertices x 9
instances as a rect list when character creation opens (#3832).

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
unknown. A payload on a PS5 (firmware 13.60) reads mode 2 and submode 0;
nothing past the two ints is written and the result register holds no

and ignores the result.

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_interpolant_mapping runs the dbOlWdppb4o vectors and OpenAGC's
enhanced-mapping vectors through it.

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.

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

sceKernelAvailableFlexibleMemorySize and the flexible maps counted only
explicit flexible mappings, so the full 448 MiB was reported while the

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

Deathloop (PPSA01670) imports sceHttpAbortWaitRequest; Planet Coaster

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.

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

FPOrdNotEqual32 already uses, which gives the same result for every

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.

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.
The bundled SDL builds its PipeWire, PulseAudio and ALSA drivers only
when their development files are found, and otherwise keeps just the
silent dummy and disk drivers without an error. The Linux CI and

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.

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,

lseek on a non-directory descriptor no longer takes the directory table lock when no directory is open, and a listing is read under the descriptor's own lock. SEEK_CUR with offset 0 only reports the position, and an overflowing SEEK_CUR offset reports EOVERFLOW.
The f16 forms of v_fma_mix threw for any FLOAT_MODE with an f16 rounding
other than to nearest even. ps5-opengl's shaders run with FLOAT_MODE

The exact product-sum, already computed in f64 with round to odd, is now
rounded once in the mode's direction: scaled by the f16 step at its
exponent, truncated, floored or ceiled, and scaled back. A result beyond
65504 becomes infinity or 65504 as IEEE 754 gives for the direction. On
RDNA2 (gfx1036) -1.5 * 2^-24 + 2^-126 gives 0x8002 with round toward
-infinity, and this gives the same. Flushed f16 denormals still throw.

Two catalog titles stop on the absent libSceLibcInternal export reallocf
(YMZO9ChZb0E) on main 0f863c10:
- PPSA97510 PSXS5 2.2.0
- PPSA98510 SwanStationPS5 1.1.3
FAIL: unresolved ELF import YMZO9ChZb0E from libSceLibcInternal.prx
reallocf follows FreeBSD 11 lib/libc/stdlib/reallocf.c (freebsd-src
stable/11 5ed7eb0d97ba4436218e810f61bd059acba984c2) on top of the guest
realloc: it reallocates through the application heap, and when realloc
fails (the application allocator returns null or the default heap
rejects the size) it frees the block through the same allocator, sets
ENOMEM and returns null. Size 0 frees and returns null as realloc does
here, so the block is not freed twice. Other heap failures throw, as
for realloc. The NID matches tools/nid_names.py and aerolib.
The application heap tests cover grow, shrink, a null pointer, size 0
and failure with both the replacement and the default allocator.

The half-wave scan rules for 32-lane hosts made lane 31 of a matched
scan a subgroup reduction and threw on a device without subgroup
arithmetic, where the read used to build as a shuffle of the scan. Such
a device now keeps the shuffle for lane 31; lane 63 still reads the
identity, which needs no arithmetic.

A wave64 vertex program runs at one guest lane per invocation, so on a
32-lane host subgroup its lanes 32-63 have no invocation. The vertex
entry still set s3 = 64 | 64 << 8, telling the program that its wave
holds 64 vertices and 64 primitives. An NGG culling program then keys a
full-wave OR on lane < s3's primitive count, lanes 32-63 hold real cull
results, and its v_readlane_b32 of lane 63 cannot be built (#2783).
The entry now sets s3 = 32 | 32 << 8 for a wave64 program on a 32-lane
host, the wave the host runs; the console launches waves with fewer
vertices and primitives. The host subgroup width reaches the vertex
input the way it reaches the compute and mesh inputs
(BuildShaderStageInputInfo from HostSubgroupSize), and the source,
prepared-shader and disk cache keys already carry it for every stage.
Programs that do not read s3 are unchanged; wave32 programs and other
host widths keep the full wave.
The keys are then 0 in lanes 32-63, so the read is sound. On a 32-lane
host, when the existing half-wave scan rules fail, the scan may also:
- run under s_mov_b64 exec, -1 (EXEC constant true);
- use bound_ctrl:1 row_shr steps when 0, the fill, is the identity (OR,
add, unsigned max), also into another register, whose old value never
shows since such a step writes every lane;
- take keys shown to be 0 in lanes 32-63: built from 0 through selects
under a lane id or v_mbcnt of -1 below at most 32, v_cmp_ne_u32 against
0, ORs, DPP and permlanes, in stages whose entry EXEC is every lane.
Lane 63 is then the identity and lane 31 the subgroup reduction of the
host's invocations. A shuffle from lane 31 is not enough: an RTX 5070
runs the vertex warps of a non-indexed triangle list with 30 of their 32
invocations. A v_readlane_b32 outside the host subgroup of another value
that is 0 in lanes 32-63 reads 0. Only reads that used to throw change,
besides lane 31 of such scans.

The macOS image initializer called a guest module's DT_INIT with no
arguments, so a module started with sceKernelLoadStartModule never saw
its args and argp, and its result was dropped. The Linux writer already
calls DT_INIT through libkernel's pending argument handoff. On the
macOS port, the PSN plugin of PPSA12544 refuses to start without its
argument block ("PSN is an old version that cannot be used by the
current player runtime") and the title then crashes.
A guest module with DT_INIT now gets two slots bound to
__aps5_get_pending_module_args_nid_no_patch and
__aps5_set_module_init_result_nid_no_patch, and its initializer calls
DT_INIT with the args and argp that sceKernelLoadStartModule records,
as on Linux, then hands the result back. The TechnicalDebt sentence
about the missing arguments on macOS is removed.
guest_module_args also relinks its fixture with --macos and checks the
two binds; on x86-64 macOS it loads the module and checks that DT_INIT
receives the arguments and that its result is returned.

FreeBSD fchdir(2) changes the working directory to the directory referenced by a descriptor. The guest imports fchdir from libkernel_sys (PPSA99764, issue #1578) and the module did not export it.
The descriptor's directory is resolved from the path recorded when the directory was opened on Windows, and from the /proc/self/fd link target on Linux. The guest working directory is then set through the libc routine shared with chdir. A descriptor that is not open returns EBADF and one that is not a directory returns ENOTDIR.

C17 7.21.6.2p16 returns EOF only if input fails before the first conversion completes, and a suppressed conversion completes. FreeBSD counts it in nconversions (vfscanf.c, releng/11.4, lines 799-805). The host scanf returned EOF there, so sscanf("12", "%*d%d", &v) reported EOF instead of 0. Each suppressed conversion now records its end with a %n and a result of EOF becomes 0 when one was recorded.
PSXS5, SwanStationPS5 and Nuvio stop at start-up on setcontext on main,
and EVO Player and ProsperoStore do on Windows. The three are imported
by the statically linked OpenSSL's ASYNC code.
The three use FreeBSD 11's amd64 ucontext_t (mcontext at 0x10, mc_len
800, uc_link at 0x330, 0x370 bytes), which the titles are built
against: EVO Player's ASYNC_is_capable captures into a 0x370-byte stack
buffer, and async_fibre_makecontext sets uc_link at 0x330 and uc_stack
at 0x338. getcontext saves every register at its call in assembly and
stores the context as FreeBSD's sys_getcontext does: rax and rdx as 0,
the carry flag clear, the FXSAVE image and the signal mask, and nothing
from uc_link on. setcontext checks mc_len and mc_flags as set_mcontext
does, installs the signal mask, masks MXCSR with the host's MXCSR_MASK
and returns through iretq, so every general register and the flags are
restored and nothing is written below the target stack pointer.
makecontext follows FreeBSD 11's amd64 libc.
Windows checks guard-page growth and exception unwinding against the
stack bounds in the TEB. setcontext and longjmp now set them to the
stack they switch to, which makecontext registers and pins writable as
libSceFiber does for fiber stacks. OpenSSL enters a context with
setcontext and then switches with _setjmp and _longjmp.

DecodeShaderStages accepts LS, HS and an NGG passthrough ES, reads the
3-bit VGT_TF_PARAM fields, refuses its other bits but DISTRIBUTION_MODE,

Local and domain programs are prepared with their stage group: its
headers are merged over one set of defaults, and a local program left
unbound by the hull header is prepared at its first draw.
The local program ends at its jump into the hull half.
TessellationLowering lowers LDS and ring addresses that are affine in
the control point and relative index to tessellation interfaces with
strides from the code, and refuses accesses outside the patch, per-patch
writes from other control points and a modified primitive export. Hull
lanes read their own saved exec bit, also of host-subgroup-masked
copies; other masks are refused, gl_InvocationID loads as a scalar and

agc_driver_dcc_keys_first_write only exercises the import window when the
device's own host import resolves the write protection of the imported
pages, as the NVIDIA driver does on Linux. CI's devices do not, so the
comparison that #2984 adds for BlockMaybeWritten units is not run there.
RunImportWindow opens an import window itself over a pending storage
image with GuestMemory::ImportWatched and stores the byte already there,
which leaves the same stamp without depending on the driver: the image
must stay pending and unchanged. A store of a new byte inside a window
must still be seen. Devices whose imports are compared print that the
window is not tested, as the recorder's (w) test does. Linux only: the
Windows path compares imports.
TechnicalDebt records that an identical-byte CPU store inside a window
cannot be told apart from the import, and that images tracked by layer
still upload again.

Two defects found in review of the Linux delivery:
A raise right after scePthreadCreate reached the new thread before
RunThread set currentThread, so scePthreadSelf() in the handler adopted
a second handle, and could deadlock on glibc's thread lock when the
signal interrupted pthread_getattr_np. The creator now blocks all
signals around the std::thread construction, so the child starts with
them blocked, and RunThread restores the creator's mask once the thread
is registered, as libthr does. A raise in that window stays pending and
is delivered just before the entry runs.
A handler that set reserved MXCSR bits made rt_sigreturn fail with
SIGSEGV. The MXCSR the handler leaves is now masked with the frame's
MXCSR_MASK (0xffbf when it reads 0), as FreeBSD's fpusetregs does, on
both platforms; Windows also keeps CONTEXT.MxCsr equal to
FltSave.MxCsr.
guest_raise_exception raises right after each of 50 thread creations and
checks scePthreadSelf() in the handler, and its context round trip sets
a reserved MXCSR bit and FZ and checks that only FZ is kept.

sceKernelRaiseException threw on Linux, so a title whose garbage
collector stops threads with it (Unity's PS5Util raises SIGUSR1 on each
thread and reads mc_rsp from the handler's context) could not run there.
The raise now sends the host SIGUSR1 to the target thread with
pthread_kill. The host handler, installed on first use with SA_SIGINFO
and SA_RESTART, builds the FreeBSD-layout ucontext from the interrupted
registers and the FXSAVE area, calls the guest handler on the target's
own stack and writes the registers back, so the handler's changes reach
the interrupted code, as they do on Windows. errno is left as the
handler leaves it, as libthr does.
A raise on another thread takes the target's join lock with the host
signal blocked and returns ESRCH once the thread has finished, so a
detached thread's pthread_t is never signalled after it exits. The
pthread_t is recorded when the thread is created or adopted. Handlers
are now lock-free atomics, as the host handler reads them.
guest_raise_exception now runs on every platform. It also checks that
r13 and xmm8 reach the handler and that r12 and xmm8 written by the
handler reach the interrupted code.

The typed descriptor heaps write a null descriptor for a null guest
image, and the device therefore required VK_EXT_robustness2's
nullDescriptor. MoltenVK has the extension but not the feature, so on
macOS no Vulkan device opened and every GPU test was skipped. The
feature is now enabled when the device has it. Without it, the device
creates a placeholder image per typed image heap: 1x1, cleared to zero,
of the heap's dimension, sample count, numeric class and access, and a
null guest image binds the placeholder of its heap. A heap whose
placeholder the device cannot create throws when a null image reaches
it. TechnicalDebt.md lists where a placeholder differs from a null
descriptor.
agc_placeholder_images checks every image resource the recompiler maps
to a heap against that heap's placeholder, so the two cannot drift
apart, and agc_shader_device_profile now expects a device without
nullDescriptor to be accepted.

A system SDL2 that does not define SDL_JOYSTICK_HIDAPI (sdl2-compat over
SDL3 ships no such macro, and neither does a build with the driver
disabled) fails pad_sdl and makes the disk audio driver open the port
with a different channel count, so ANYPS5_USE_SYSTEM_DEPS=ON now rejects
it with a named error, like the VK_KHR_maintenance8 check. Ubuntu's real
SDL2 defines the macro through its SDL_config.h indirection and is
unaffected.
SPIRV-Tools only exports SPIRV-Tools-static when built with
SPIRV_TOOLS_BUILD_STATIC=ON; distributions that ship it shared expose
SPIRV-Tools instead, so a shared target is aliased to the static name.
Resolve SDL2, freetype, Vulkan-Headers, SPIRV-Headers, glslang and
SPIRV-Tools from the system instead of the bundled submodules when the
option is ON. It is OFF by default, so the bundled build is unchanged.
Every package is required: a missing one, or Vulkan-Headers older than
1.4.310 (the agc driver uses VK_KHR_maintenance8), fails the configure
with an error and nothing falls back to the submodule. The system
packages are exposed under the same target names the bundled path uses,
so the rest of the CMake is untouched.
SDL2 is linked from the system as a shared library because the prx
libraries are shared objects and distribution static SDL2 is usually not
PIC. ffmpeg-core, libjpeg-turbo, stb, VulkanMemoryAllocator and LibAtrac9
stay bundled.
sceSharePlayGetCurrentConnectionInfoA now writes a 72-byte

code; KytyPS5 sets the user IDs to -1, fpPS4 leaves them 0.

Relinks the ELF modules of extra directories under the module parent directory. Modules the executable or another module needs start with the executable; the others are initialized when the title loads them with sceKernelLoadStartModule, with its start arguments (Windows: __aps5_guest_initialize export; Linux: left out of DT_NEEDED).
Squashed onto main by the reviewer (history had a merge commit).
Explicit-LOD offset samples through FORCE_UNNORMALIZED samplers now add
sign-extended texel offsets to f32 coordinates before clamping, using
OpFAdd with NoContraction and a sampler specialization selector.
Without native nonconstant-offset support, retain only runtime image
modes valid for unnormalized sampling and reject normalized samplers.
Preserve constant-swizzle handling, indirect-image rejection and main's
flat-volume and flat-line compatibility rules when selecting those modes.
Serialize image compatibility and folding flags and the sampler folding
flag in cache format 34, with roundtrip, preparation and execution coverage.
Retain main's request format 15 and runtime ABI 11.
