A raised exception redirects the target thread to a stub that runs the handler and returns through RtlRestoreContext. On Windows 10 (19045) RtlRestoreContext restores in user mode only when the context flags are exactly CONTEXT_FULL | CONTEXT_SEGMENTS (CONTEXT_XSTATE aside); for the CONTEXT_FULL | CONTEXT_FLOATING_POINT context it was given, it calls NtContinue. When the next raise suspended the thread inside that system call, NtContinue then replaced the redirected context with the one it was restoring, so the handler never ran although sceKernelRaiseException had returned 0. guest_raise_exception lost such a delivery to its busy thread in about one run in five and hung until the ctest timeout.
The context is now read with CONTEXT_SEGMENTS, so the handler returns through the user-mode restore, and a raise that finds the thread inside NtContinue or NtContinueEx (an APC or an exception handler returning) resumes it and suspends it again.

libSceVoiceQoS.sprx: a null block, any size other than exactly 0x40000,
and an app type other than 0x20000000 or 0x10000000 all return
0x804E0902 without touching the block, instead of throwing. A second

Add scePadOpenExt for special ports, which return DEVICE_NOT_CONNECTED because the host has no special controller, and the extended read and report exports, which throw.
The LOD warning lwe adds to the texel status is texture-streaming feedback,
which is not reported for the T# MIN_LOD_WARN either. Accept lwe on sample
and gather instructions as it already is on loads and stores; lwe on
image_get_lod still throws.
Once an image has .ehmeta, an eh_frame_hdr version other than 1, an
eh_frame_ptr encoding other than absptr or pcrel, a 64-bit record length,
an eh_frame_ptr outside the image or a missing terminator now throw
instead of returning the empty answer. The test queries a fixture DLL
whose .ehmeta it can break, since the unwinder reads the same section.

Opening a save progress dialog immediately reported FINISHED. Skyrim

progress-bar mode running through polling and progress updates until
Close, retaining the existing automatic responses for other dialog modes.
Add lifecycle regression coverage for repeated polling, completion,

The weekday is required in any case or length, month names may be
full, RFC 2822 and RFC 850 share one lenient grammar with 2-digit years
split at 50, and the asctime zone is ignored. Zones come from a name

console rejects returns a parse error with the tick untouched, and an
invalid calendar date returns 0 with only the offset applied to the

A year before 1980 or after 2107 cannot be packed into the DOS time, so
GetDosTime threw. Following the disassembly-derived fpPS4
reimplementation of the PS4 library, it now returns INVALID_YEAR after
writing 0 for an earlier year and 0xff9fbf7d, the largest encodable
time, for a later one. The TechnicalDebt entry now records fpPS4 as the
source for the SetDosTime year decode as well.
A captured grain stored only the port slot and data pointer, so a port
created in a destroyed port's slot before the next push mixed the old
pointer with its own format. Ports now carry a generation that the
capture records. TechnicalDebt notes that the last grain pushed before a
title stops is never played.

A wave64 graphics program on a 32-lane host runs one guest lane per
invocation, yet an EXEC written as a value keeps all 64 bits: the NGG
prologue's s_lshr_b64 exec, -1, 64 - count reads count 0 and sets -1.
A waterfall loop that copies EXEC with s_mov_b64 and retires one key
per pass then never empties its copy, since no ballot sets the lanes
the host lacks, and its v_readlane picks lane 32 and up.
readRawU32 now ANDs EXEC with a ballot of true when it is read as a
value (s_mov_b64, ALU sources, src_execz), and s_*_saveexec and
s_*_wrexec store that masked copy. EXEC's own words, threadBit and the
saveexec combination keep the raw words, so s_orn2_saveexec_b64 vcc,
exec still sets all 64 bits. On subgroups under 32 lanes the EXEC_LO
copies of agc_driver_scalar_sop1 now hold only the subgroup's lanes.
The Smurfs Dreams imports both and no library exports them, so eager
binding stops the title before it starts. sceAudioInAsyncOpen throws
like the other AudioIn opens that have no implementation;
sceHttp2SetMinSslVersion returns success like the other Http2 SSL
setters, as no request reaches the network.

The APC delivery was allocated after SuspendThread, so a target holding
the allocator lock deadlocked the raising thread; it is now allocated
before the suspend. The wait count a raise checks lived in the target's
thread_local storage and dangled once the thread exited; it is now a
member of PthreadPrivate, which TimedWait counts into through a
thread-local pointer bound when the thread starts, and a raise on a
thread that already finished returns ESRCH. TechnicalDebt gets one line
per unverified choice: Windows only, the FreeBSD ucontext layout, the
signal mask, the YMM upper halves, and delivery to threads outside
TimedWait.

PPSA03306 (Silt) loads the Unity plugin Media/Plugins/PSNCore.prx, which

Eight libSceAgc exports were published under a raw NID with a made-up

PPSA01325 stops on sceFontGlyphDefineAttribute right after generating a character glyph: it sets attribute 0x11 to 0 on that glyph, deletes it without using it, and draws the character with sceFontRenderCharGlyphImageHorizontal.

PPSA16064 (Minecraft Dungeons II, Unreal Engine) failed to load because
these imports had no export:
- libkernel: sceCoredumpWriteUserString
- libSceSaveData: sceSaveDataConvert, sceSaveDataGetConvertProgress
- libSceVideoOut: sceVideoOutVrrPegToFixedRate,
sceVideoOutVrrUnpegFromFixedRate
None of them is called during the title's start-up, so they are added
as unimplemented exports that throw with their name if a title calls
them. Their signatures are unknown; TechnicalDebt records them. The
built libraries export the NIDs the title imports.
Every command writer checked bottom <= cursor_up <= cursor_down <= top.
PPSA16064 (Minecraft Dungeons II, Unreal Engine) builds small one-packet
buffers (8 dwords) with cursor_down left null, and the first
sceAgcDcbCopyData into one threw "invalid command buffer cursors".
Nothing in the library allocates downward, so cursor_down only bounds
the space above cursor_up. A null cursor_down now means that bound is
top. Non-null cursors are checked as before. TechnicalDebt records the
assumption.
agc_commands writes six dwords into such a buffer and checks that a
further allocation past top fails without moving the cursor.
NID fCWdlnmB1Ks was exported as an unknown function that threw. The
name scePadIsRemoteController hashes to it. PPSA16064 (Minecraft
Dungeons II) calls it once per controller after
scePadGetControllerInformation, with the pad handle and the address of a
byte it has just zeroed, and ignores the result.
It reports whether the controller is connected through Remote Play.
Controllers here are local devices, so the answer is always false. An
invalid handle returns INVALID_HANDLE and a null output INVALID_ARG, as
the other pad calls do. Without it the title aborted at the main menu.
scePadSetAngularVelocityBiasCorrectionState, which the title imports but
does not call during start-up, is added as an unimplemented export.
guest_pad checks the handle and null-output errors and the result.
sceHttp2SendRequestAsync no longer fails synchronously: it queues a
completion carrying the network error and triggers the user event named
by the kqueue option. sceHttp2WaitAsync returns queued completions.

Refs #981
Storage images of a SINT format threw "storage image descriptor uses
an unsupported format"; only write-only 32_SINT was accepted.
The recompiler now writes 16_SINT, 8_8_SINT, 32_SINT, 16_16_SINT,
8_8_8_8_SINT, 32_32_SINT, 16_16_16_16_SINT and 32_32_32_32_SINT
storage images with the Uint numeric class. 8- and 16-bit components
are saturated (EmitFormatStoreComponent) and 32-bit ones stored
unchanged, as measured on RDNA2 (gfx1035); image_store_pck stores
32-bit components unchanged too. The driver binds these surfaces
through a cached view of the same-size UINT format.
8_SINT, 32_32_32_SINT, the packed SINT formats (11_11_10, 10_11_11,
2_10_10_10, 10_10_10_2), D16 stores, packed stores of 8- and 16-bit
components and atomics other than 32-bit ones on 32_SINT and 64-bit
ones on 32_32_SINT still throw. New test: agc_driver_image_store_sint,
with DST_SEL X,Y,0,1 on the two-channel formats, as with X,Y,Z,W the
hardware writes channel 1 from the W data slot (TechnicalDebt).
NVIDIA 610.62 cannot sample R8G8_SRGB, and lavapipe can sample neither
it nor R8_SRGB, so an 8_8 sRGB T# made an image the device does not
support: creating it crashes the NVIDIA driver and lavapipe loads zeros.
The device's format support is read once. An 8 or 8_8 sRGB texture the
device cannot sample is created and viewed as R8_UNORM or R8G8_UNORM,
and SpirvTarget::srgbDecodeFormats makes the materializer mark the
image, so image loads map every channel through a 256-entry table of
the sRGB EOTF rounded to nearest even at bf16 precision, which is what
RDNA2 (gfx1035) returns; both channels of 8_8 are sRGB, and DST_SEL 0
and 1 map to themselves. Samples and gathers of such an image throw,
and its bindless table entries are unmapped like converted formats.
APS5_SRGB_SHADER_DECODE=1 takes this path on every device. Shader disk
cache entries and keys carry the mark: cache format version 7.
DS opcodes 0x6e and 0x6f exchange two qwords at offset0 and offset1
scaled by 8 (st64: 512) and return both old values. Each address is
exchanged with its own 64-bit LDS exchange on the locked 64-bit path.
Equal offsets and a destination past v255 throw, as for the b32 forms;
64-bit GDS throws like the other 64-bit DS atomics.

Comparison sampling of a color texture threw on the _o, _b and _cl
forms and on a sampler LOD bias. The emulation fetches the texels
itself, so the 6-bit offsets of the address are added to the point or
bilinear texel indices, as on the hardware and in Vulkan. The emulation
runs only at level zero or on a single-level view, where an LOD bias or
clamp cannot select another level, so they are accepted with no effect.

LookBackScan runs a 43-instruction decoupled look-back written for the
test: one aggregate per block, the block index from an atomic counter,
{flag, value} published with buffer_atomic_swap_x2 and read back with
glc buffer_load_dwordx2. Seven single look-backs and 50 scans of 4096
blocks are checked against a CPU prefix sum; without the recompiler
change the first whole scan fails (3 of 3 runs).
TechnicalDebt records that only glc, aligned, in-bounds dwordx2 loads
in programs with the 64-bit storage view are one atomic load: loads
without glc, and loads in programs without 64-bit buffer atomics, can
still tear against a concurrent swap_x2.
image_atomic_* with a two-dword data mask (four for cmpswap) is the
64-bit form of an integer image atomic. The decoder rejected it with
"invalid MIMG data mask". PPSA14632 (Unreal Engine) uses
image_atomic_umax this way in a compute shader during its first frames.
Swap, add, sub, signed and unsigned min/max, and, or, xor and cmpswap
now decode with 64-bit data and translate to new ImageAtomic*64 IR
opcodes. An image updated by them gets its own descriptor binding
range, declared as an R64ui image of 64-bit integers, and the module
uses Int64ImageEXT from SPV_EXT_shader_image_int64. The driver enables
shaderImageInt64Atomics when the device offers it and binds an
R64_UINT view of the 32_32 UINT, SINT or FLOAT surface. Without the
feature, recompiling such a shader throws.
64-bit inc, dec and the float atomics still throw, as does any other
access in the same shader to an image it updates with 64-bit atomics.
The new agc_driver_image_atomics64 test runs every operation on 32_32
UINT, SINT and FLOAT surfaces and checks the returned and stored values
against edge cases across the dword boundary.

The resource tracker refused a program's 33rd distinct V# with "buffer
resource limit exceeded". The 32 was a recompiler constant, not a
Vulkan limit: every buffer is one constant-indexed element of the guest
buffers binding, which ShaderResources checks against the device's
storage-buffer limits.
Drop ShaderInfo::MaxBuffers and the tracker's refusal, and size the
SPIR-V emitter's per-buffer offset list from the binding layout. When
the user data and offsets do not fit in the push constants, they all go
to the shader data buffer as before. ShaderResources counted only
storage buffers against maxPerStageResources (200 on Intel UHD) and now
adds the stage's sampled and storage images.
agc_driver_many_buffers reads and writes 52 and 124 buffers, and
agc_driver_graphics rejects buffers plus an image above the limit.
An S# with FILTER_MODE (word0 bits 29-30) set threw in
DecodeSamplerResource. Modes 1 and 2 now map to Vulkan's MIN and MAX
sampler reduction through VK_EXT_sampler_filter_minmax, which the device
enables when it reports both filterMinmax properties; mode 3 throws.
Min/max still throws with anisotropy, a linear mip filter (lavapipe and
NVIDIA disagree there), depth comparison, color-texture compare
emulation, and, in PointFilteredSamplerWord (S# words 0 and 2), when it
filters between texels or mips of an image the recompiler point-samples.
A texture sampled through a linear min/max sampler needs
SAMPLED_IMAGE_FILTER_MINMAX on its view format; the image-sampler pairs
travel in DescriptorBinding::imageSamplers (shader disk cache format 5).
Adds the agc_driver_image_sample_reduction GPU test and extends the
sampler, emulated color compare and disk cache tests.
RADV (Mesa 26.0 and later) initialises a FREE_DESCRIPTOR_SET pool's
allocator with bo_size + RADV_POOL_HEAP_OFFSET as its size, so a set can
be placed up to 32 bytes past the pool's buffer. The chain pools are
0x26000 bytes, a page multiple, so a set at the end of a full pool has
its last descriptors on an unmapped page: the CPU descriptor write
faults, or the shader's scalar load raises a GPU page fault and the ring
is reset.
Two more storage buffer descriptors make the pool 0x26020 bytes; the
buffer's last page then holds those 32 bytes.

CB_COLOR_INFO format 1 with number type 6 (8_SRGB) threw at decode.
It now decodes as R8_SRGB with component swap 0; the other swaps and
8_8_SRGB still throw.
A device that cannot attach and blend R8_SRGB (NVIDIA, lavapipe)
renders a resident 8_SRGB target through an RGBA8_SRGB view of an
RGBA8 copy of its R8 image: the image is blitted in before the pass
and back when the pass ends, and the write mask keeps R only, so the
encode, decode and blend are the device's sRGB attachment rules.
APS5_SRGB_ATTACHMENT_PROXY=1 forces the copy. Linear, mipmapped and
3D 8_SRGB targets throw on such a device.
PPSA26344 renders its G-buffer slot 5 and a multiply-blend pass into
8_SRGB targets.
LEGO Horizon Adventures imports 19 functions that no library exports

A title maps direct memory with protection 0x3f2, which adds bits
0x100 and 0x200 to the CPU, GPU and AMPR bits, and the mapping threw.
They are the audio coprocessor (ACP) read and write bits, as named in
the KytyPS5 and etaHEN headers. The coprocessor work runs on the host
CPU, so they map to host read and read/write access like the GPU bits.

The mixing stage threw when a mastering voice and its render buffer had different channel counts. A 2-channel voice is now mixed into the first two channels of a 6- or 8-channel buffer; other mismatches still throw.
Driver::RegisterShader required the Shader header at an 8-byte
boundary (alignof(Shader)) and read its fields through the pointer.
PPSA26344 uses its shader packs in place: its compute shader objects
point at headers 4 and 1 bytes past an 8-byte boundary, so the first
sceAgcCreateShader of such a header threw "null or misaligned address".
The header is now checked for null and readable memory at any
address, and its fixed fields and the registers the trace prints are
copied out with memcpy. The code address must still be 256-byte
aligned, and the header and size checks are unchanged. The console's
rule is unknown and is listed in TechnicalDebt.
The call site of PPSA21402 sets only three argument registers, so the function has no size parameter. A data chunk that runs past the buffer or ends inside a frame returns INVALID_WAVEFORM_DATA instead of being shortened. The test no longer writes padding from a string literal.

A pixel, vertex or tessellation stage whose wave is wider than the host
subgroup runs one guest lane per invocation, so lanes at or above the
subgroup size have no invocation. v_readlane_b32 still shuffled from
them, which Vulkan leaves undefined; a wave64 pixel minimum loop that
reads lanes 31 and 63 can then wait for a value no live lane holds and
hang the GPU.
At one lane per invocation outside compute, a v_readlane_b32 of a
constant lane at or above the host subgroup size, and v_permlanex16_b32
on a subgroup of 16 lanes or fewer, now fail SPIR-V emission. Lanes in
registers still build, so s_ff1_i32_b64 waterfalls are unaffected,
and neither check applies to compute or to two lanes per invocation.
v_permlane16_b32 and v_permlanex16_b32 take the source lane's EXEC from
a ballot, as DPP does, instead of a shuffle from a possibly inactive
invocation.
GFX10 image format 30 (10_11_11_UNORM: X and Y are unorm11 in bits
0-21, Z is unorm10 in bits 22-31, per Mesa's gfx10 tables) has no
Vulkan format, so its sampled and storage descriptors threw at decode.
Format 30 now takes the R32_UINT route of 10_11_11_UINT: the driver
binds the raw dwords as R32_UINT and the shader extracts each field and
converts it with the buffer format helpers (NormalizeFormatComponent on
loads, EmitFormatStoreComponent on stores); DST_SEL 1 reads 1.0f.
Samples, gathers, LOD queries, 16-bit data and loads or stores whose
DST_SEL names the missing W channel throw.
Converted textures are now viewed with an identity component mapping,
since the shader applies DST_SEL itself: a 10_11_11_UINT view whose X
selector was not X lost the packed dword. DCC clear codes 0001 and 1110
of a converted texture throw instead of filling one R32_UINT channel.

sceWebBrowserDialogGetResult and like the sign-in dialog, so a title takes its "no user chosen"
path instead of reading an invalid user id. Records the dialog in the silent-stubs list in
docs/dev/TechnicalDebt.md.
Per review: sceUserServiceGetNpAccountId reports success with account id 0 and
sceUserServiceGetUserColor returns blue by default; both are assumptions. Records them under
"Unknown function info" in docs/dev/TechnicalDebt.md.

sceAgcCbCondWrite writes the 9-dword COND_WRITE packet: poll a memory
dword, compare it masked with the reference, and write a dword to memory
on a match. sceAgcCbCondWriteGetSize returns its 36 bytes.

sceAgcAsyncCondExecPatchSetCommandAddress and

The query writes the maximum resource name length (0xfc) through its

sce::Agc::ResourceRegistration::getMaxNameLength(unsigned int*). Resource

Rack 0x2001 is created with its option layout and KytyPS5's defaults, takes
the setup (0x20010000) and I3DL2 (0x20010001) voice params and reports the
common voice state. The voice mixes its inputs and runs a Freeverb-style
approximation driven by the I3DL2 parameters: room and room HF, early
reflections and their delay, late reverb and its pre-delay, decay time and
HF ratio, and diffusion. Out-of-range params throw, param changes keep the
tail, a stop or kill clears it, and the tail ends once it decays below
1e-20. The console's algorithm is unknown; the approximation is recorded in
TechnicalDebt. The test context buffer pool grows to 64.

Whether the console's parser rejects 1e309 or stores an infinite real
is unknown, and RFC 8259 allows both. Following the exact-or-throw rule,
sce::Json::Parser::parse now throws with the number text and a note that
the behaviour is unverified, instead of returning JsonErrorParse. The
partially built tree is freed before the exception leaves the parser.
The case is listed under unknown function info in TechnicalDebt.md.

sceAgcWriteDataPatchSetDst, sceAgcWriteDataPatchSetCachePolicy, their
Async forms and sceAgcAsyncWriteDataPatchSetAddressOrOffset threw. They
now rewrite a WRITE_DATA packet in place: the destination in the
graphics (sceAgcDcbWriteData) or compute (sceAgcAcbWriteData) encoding,
the cache policy in bits 25-26 and the address in dwords 2-3, so the
patched packet equals the one written with those values. A register
destination is rejected when the packet requests write confirmation,
as when the packet is written.

PPSA14632 (Unreal Engine) writes sceAgcCbBranch(mode 1, compare
function 0, mask 0, reference 0) with a then buffer and a null else
buffer of 0 dwords. It leaves the compare address uninitialised, so it
is sometimes only 4-byte aligned. The writer rejected the null else
buffer and the misaligned compare address, and the driver accepted
opcode 0x3f only as the 4-dword INDIRECT_BUFFER, so the 14-dword branch
would have failed at submission.
sceAgcCbBranch no longer checks the compare address of an always-pass
branch, which reads nothing, or the address of a buffer of 0 dwords.
The driver runs the first buffer of an always-pass COND_INDIRECT_BUFFER
in modes 1 and 2 (if-then and if-then-else) in place of the packet. A
comparison, a predicated branch and other modes throw.

The 106-key (Japanese) arrangement threw. Its alphanumeric layer now
follows the JIS layout of the HID usages: the symbol keys right of the
digits and letters, the Ro key (0x87) and the Yen key (0x89). With the
Kana LED set it still throws, as the kana the console returns are
unknown.

sceAjmBatchJobControl threw. It now appends a control job that keeps
the sideband input pointer and runs at sceAjmBatchStart: RESET (bit 13)
clears the context as sceAjmBatchJobClearContext does, INITIALIZE
(bit 14) initializes the codec, and SIDEBAND_GAPLESS_DECODE (bit 45)
overwrites the gapless total and skip counts, in this order.
The sideband input holds the gapless decode first, then the codec's
initialize parameters: 8 bytes for ATRAC9, 12 for Opus, none for MP3.
The output is the 8-byte result. Other flags, INITIALIZE for other
codecs, and other sizes throw. SIDEBAND_GAPLESS_DECODE without RESET
throws too: RPCSX and shadPS4 keep zero counts there. The bits and the
order follow shadPS4 (PS4), the overwrite with RESET follows RPCSX, and
the sizes follow the one title seen.
PPSA14632 calls sceAudioOut2Set3DLatency(0xFF, 1) during its audio
setup (eboot 0x5613e2c) and fails the setup on a nonzero return. Only
latency 2 from PPSA26344 was accepted, so the call threw. Latency 1 and
2 are now accepted for the system user; 0, 3 and other users still
throw.

scePlayerInvitationDialogGetResult makes the common dialog checks of
sceWebBrowserDialogGetResult: NOT_INITIALIZED before the dialog is
initialized, ARG_NULL for a null result and NOT_FINISHED until the
dialog finishes. The dialog shows no UI and sends no invitation, so the
finished dialog reports USER_CANCELED with error code 0. The 40-byte
result layout (error code, result, 32 reserved bytes) is taken from
SharpProspero.

The plain-named twin of std::_Execute_once delegates to that symbol and inherits its call_once semantics; the name-equivalence assumption is recorded in TechnicalDebt. Registers guest_std_execute_once_tests.
A second sceSaveDataInitialize3 returned SAVE_DATA_ERROR_ALREADY_INITIALIZED.
PPSA12544's executable and its Unity SaveData plugin both initialize, and
the plugin raises Unity.SaveData.PS5.Core.SaveDataException on any error,
so the console must accept the second call. Initializations are now
counted; sceSaveDataTerminate ends the session at the last one and only
then checks for mounted slots.

A push mixed the ports' buffers at once and queued the mix on SDL, and
the queue level left out a 40 ms cushion that the SDL queue rarely
exceeded, so titles saw an empty queue. PPSA12544's FMOD output fills a
256-frame buffer after pushing it, reuses it two pushes later, and its
mixer thread can still be writing a buffer when the next push follows
within microseconds: a grain boundary broke about every 5 ms (an audible
crackle).
A push now records the buffers the ports point at and reads the previous
grain at the next push, 100 us after it. The mixed frames are played by
the SDL device callback, which waits for a 40 ms cushion before it plays
(again after running dry), and the queue level counts the unplayed
grains beyond that cushion. Recording the four buffers at every push
showed 27% of boundaries broken when read at the push, 59% when read two
pushes later and none when read at the next push; the title's output
went from 4-9% to none of its grain boundaries broken over 6,000 loud
grains.

A title's libc.prx passes the dso address of __cxa_thread_atexit to
_sceKernelRtldThreadAtexitIncrement and fails the registration when it
returns nonzero. Increment takes a reference on the loaded image that
contains the address, so it stays mapped while thread_local destructors
are pending, and Decrement releases one. An address outside every
loaded image and a Decrement without a reference throw.

The resource id array is cleared and given the user. A null array returns
INVALID_ADDRESS and an invalid user INVALID_USER_ID without writing it; a
user whose keyboard is not open gets NOT_OPENED, and an open one gets
CONNECTION_FAILED, as no USB keyboard is reported through the IME, as in
shadPS4. The missing IME keyboard events are recorded in TechnicalDebt.

On a host subgroup narrower than 32 lanes, threadBit reads an EXEC
written with s_mov_b32 or s_mov_b64 at bit LaneId & 31 of EXEC_LO, and
LaneId is the subgroup invocation id. Every lane at or above the host
subgroup size therefore reads the bit of a lower lane, in wave32 and
wave64 alike. An EXEC produced by a compare stays consistent because
its ballot is subgroup-local as well. Found while investigating the
llvmpipe failure of #751.
An S# with FORCE_UNNORMALIZED threw in DecodeSamplerResource. It is now
bound through a Vulkan sampler with unnormalizedCoordinates when every
use stays where the S# and the host select the same texels.
ShaderInfoCollector records the live uses of each sampler after Apply
and dead-code elimination, and the emitter shares its explicit-LOD
predicate. Populate flags a direct S# with the bit that only explicit-LOD
image_sample without offset, comparison, derivatives or _a uses, paired
only with direct 1D or 2D images without a format conversion; anything
else throws. The driver checks the S# filters, clamps, TRUNC_COORD and
MC_COORD_TRUNC, creates the sampler with nearest mips and a zero LOD
range, and requires a single-level, single-layer 1D or 2D view of mip 0.
The shader disk cache format becomes 5.
Returns the CPU mask threads get by default (DEFAULT_THREAD_AFFINITY,
0x1FFF), the value itself rather than an error code.

PPSA21564 and PPSA21567 import std::_Fiopen (NID vYWK2Pz8vGE), the only libc
NID the host libc lacks. Without it the executable fails to load against
the host libc when the title's own libc.prx is left out of the guest
conversion, which is how the Linux runs of PPSA21564 avoid the libc.prx
binding crash. The values of the open mode and the meaning of the
protection argument are unknown, so the export throws when called; it was
never called in a 300 s run of PPSA21567.

sceVoiceQoSInit accepted only app type 0x20000000 and threw for every
other value. PPSA26344 v1.008 passes 0x10000000 at both of its call
sites, so its initialization threw.
Accept 0x10000000 as a second known app type. Its meaning is unknown,
so the constant is named after the value, and it is handled like
0x20000000; the block stays unused. A null or empty block, a second
initialization and every other app type still throw.
guest_voice_qos_tests now takes the app type as its argument and runs
in ctest once per accepted value, because sceVoiceQoSEnd still throws
and one process can initialize only once.
sceAudioOut2PortCreate threw for 12-channel ports, which PPSA26344
creates as its two 7.1.4 float beds (data format 0xc00).
Each accepted layout (1, 2, 6, 8 or 12 channels, float or int16) now
folds into the stereo mix through a coefficient table: centre, side,
back and top front channels at -3 dB, top back channels at -6 dB into
the front, LFE dropped. Zero coefficients are skipped, so NaN or Inf on
a dropped channel does not reach the mix. Ports of 3, 4, 5 or 7
channels, which were mixed as L/R, now throw, as do other counts and
formats with any of bits 12-31 set. The assumed format fields,
channel order and coefficients are listed in TechnicalDebt.
The new audio_out2_port_layouts test checks each layout's fold, float
and int16, and the formats that throw.

DecodeState, the draw precheck and DecodePixelStageInfo rejected every
nonzero CONSERVATIVE_Z_EXPORT (DB_SHADER_CONTROL bits 13-14).
EXPORT_LESS_THAN_Z (1) and EXPORT_GREATER_THAN_Z (2) promise that the
exported Z stays on one side of the interpolated Z. The value now
reaches the recompiler as a pixel stage field, and a pixel shader that
writes FragDepth declares DepthLess or DepthGreater next to
DepthReplacing, the SPIR-V modes RADV maps to these values. Vulkan lets
those modes only add a depth test of the interpolated Z before shading,
so a shader that keeps the promise renders the same. The reserved value
3 still throws.
The field is part of the recompile cache key, the draw key and the
serialized request (version 7), and ValidateShaders accepts both modes.
Initialize, PortOpen/Close, PortSetAttribute, PortGetQueueLevel,
PortAdvance and PortPush. One port, validation order and error codes from

sceVideoOutRegisterBuffers2 threw "DCC presentation is not implemented"
for category 1 (DCC-compressed) buffers, which PPSA26344 registers. Such
a buffer now needs DCC metadata and the tiled layout, and dcc_control may
only use the CB_DCC_CONTROL block layout bits 0x10026c.
At a flip the keys are read behind their recorded writers, one byte per
256 bytes as in the driver's DCC model. Uncompressed keys present the
stored texels as before; a uniform clear code presents its color with a
GPU clear of the scaler's source image; a pending storage image is used
when it serves the keys. Mixed or unreadable keys, clear codes the
display format has no DCC encoding for, register-clear keys over a
pending image and a clear color wider than 32 bits throw. Buffers
without DCC take the old path.
sceFontOpenFontSet failed for every set type, so PPSA21564 drew no text
in system fonts (the title screen copyright line, credits, button
guides). It now loads the set's primary font file from
ANYPS5_SYSTEM_FONTS, or anyps5-fonts beside the executable: console
files under their own names first, then openly licensed substitutes
(Noto Sans, Noto Sans Mono, Noto Sans Thai, Noto Sans CJK). The
PS5-only JG2 set types are accepted.
System font handles use the system font context. Their faces are
loaded by FreeType in host memory: about 1 MiB per CJK face does not
fit the font memory the title sizes for the console's fonts, and
sceFontCreateRenderer then failed with ALLOCATION_FAILED. Handles of
the same font file share one copy of its bytes.
PPSA12544's Media/Plugins modules (CommonDialog, PSN, Share) import
libSceVrSetupDialog, which no library provided, and Share, NpTrophy2,
WebBrowserDialog and NpEntitlementAccess functions that were not
exported. Add libSceVrSetupDialog and the missing functions as
unimplemented exports, except
sceNpEntitlementAccessRequestConsumeServiceEntitlement, which reports
SCE_NP_ERROR_SIGNED_OUT like
sceNpEntitlementAccessRequestConsumeUnifiedEntitlement. Their other
imports are covered by #734 and #369, and two by #407.

The executor keeps the PRT pages of the AMM ranges. Unbacked PRT pages
are zero-filled with GPU read access; AllocatePaForPrt backs each
unbacked page with a pool page and changes the type and protection of
backed ones; RemapIntoPrt moves a mapped range into a PRT range; and
UnmapToPrt returns the pages to the pool and zero-fills them again. A

sceVideoOutIsOutputSupported threw VIDEO_OUT_ERROR_UNSUPPORTED_OUTPUT_MODE
for every mode other than the default and 119.88 Hz, and
sceVideoOutConfigureOutput threw for an unavailable 119.88 Hz mode. Titles
probe and request modes the display may lack and handle the result:
PPSA12544 asks for 0xd000000a and falls back to 3840 pixels when it is not
supported, and its sceVideoOutConfigureOutput caller switches on the
returned error codes, including VIDEO_OUT_ERROR_UNAVAILABLE_OUTPUT_MODE.
Every mode except the default now reports 0, and configuring one returns
VIDEO_OUT_ERROR_UNAVAILABLE_OUTPUT_MODE.

libSceAmpr gains sceAmprAmmCommandBufferRemap, MultiMap, ModifyProtect
and ModifyMtypeProtect with their GPU mask forms and the eight measure
functions. Signatures and the protection and mask checks follow ampr_emu.
The executor keeps a page table of the AMM ranges: each page's physical
offset, protection, memory type and whether it came from the pool. A
remap moves the pages of a fully mapped range and leaves the old range
reserved; a multimap maps the same pages again; a pool page returns to
the pool only when its last mapping goes. A protection change applies
the masked bits page by page.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
libSceAmpr gains the AMM command buffer (constructor, destructor, map,
map direct and unmap, with their GPU mask forms and measures),
sceAmprAmmGiveDirectMemory, sceAmprAmmGetVirtualAddressRanges, the three
submit forms and sceAmprAmmWaitCommandBufferCompletion. The APR
MapBegin, MapDirectBegin and MapEnd commands and their measures record
the same map commands.
The libkernel executor now maps: a plain map takes pages from the direct
memory given to the mapper with usage 1, a direct map uses the given
offset, and an unmap returns the pages to that pool and leaves the range
reserved. The AMM ranges are reserved in the guest arena on first use.
Commands are walked by the buffer's byte offset so an AMM submission can
run raw command memory.
Signatures, the protection mask and the APR map rules follow ampr_emu;
the mapper model follows PS5PCEM. While an APR map region is open, a
second begin and every completion write return EPERM.

sceAmprAprCommandBufferReadFileGather, ReadFileScatter,
ReadFileGatherScatter and ResetGatherScatterState, with their measure
functions. Signatures, argument checks and the read cursor follow
ampr_emu: each read leaves the file, the next offset and the next
destination; a gather reads at a new offset into the next destination, a
scatter continues in the file into a new destination, and a
gather-scatter takes both. Recording one needs a file read since the last
reset, tracked in the command buffer object next to its type.
sceAmprAprCommandBufferReadFile now applies the same length, offset and
destination checks and rejects a null command buffer instead of
dereferencing it.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
sceAmprCommandBufferWaitOnCounter_04_00 and WriteCounter_04_00 take the
counter access size and offset, the wait mask and the write operation,
with their measure functions; ConstructNop records a nop with an optional
leading word and a payload of up to 60 bytes, and ConstructMarker records
the set, push and pop markers by type. Signatures and checks follow
ampr_emu.
The executor now reads and writes counters by access: the 8-byte access
of counter n spans n and n + 1, the 2- and 1-byte accesses a half or a
byte of the counter. Waits compare at the access width, so the signed and
wrapped compares see the field's own sign bit, and the atomic writes wrap
within the field. The legacy counter commands record a 4-byte access.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
SET_PREDICATION threw, and packets with the predicate header bit were
rejected. The executor now keeps the queue's predication: operations 3
and 4 read a 64- or 32-bit value and bit 8 selects whether predicated
packets run when it is non-zero or zero; operation 0 clears it. Before
a predicated packet runs while predication is active, queued labels are
recorded and the value is read, as for COND_EXEC; the packet is skipped
when the predicate fails.
Indirect buffers are inlined when a submission is copied, so a
predicated INDIRECT_BUFFER call keeps its header in front of the
inlined commands and records their end like a COND_EXEC range; the
block runs or is skipped on one evaluation, as on the command
processor. Query predication, a predicated COND_EXEC, predicated chains
and flips inside predicated command buffers throw.
