Allow a forward scalar branch to target reachable code after S_ENDPGM.
Preserve instruction boundaries and reaching definitions across the program-end marker.

Enable graphics subgroup lowering only when the device reports a compatible native wave size.
Pass the selected policy into shader translation and shader cache keys.
Add policy and interface tests.
* fix(agc): preserve composite depth target extents
Decode attachment width and height from composite depth binding packets and carry them separately from independent context-register state.
Detach irreconcilably mismatched depth attachments instead of shrinking color passes, with focused coverage for packet parsing and fallback behavior.
* fix(cpu): preserve full-width guest callback results
Return the complete 64-bit value from direct and worker-backed guest calls instead of truncating it to 32 bits.
Add fourth-argument support for guest callbacks and cover both ABI behaviors in the native return smoke test.
* fix(shader): key translated programs by checksum
Include programmed shader checksums in decode and compiled-pipeline cache identities so replaced code at a reused guest address cannot resolve to stale translations.
Propagate checksums through compute, graphics, and submitted-geometry translation and cover address reuse with a regression test.
* fix(agc): skip rectangle draws without parameter exports
Track enabled shader parameter exports and reject only non-indexed rectangle draws that have no vertex inputs or parameter exports but still request interpolated pixel inputs.
Treat the rejection as intentional and cover the guarded and preserved draw shapes with focused tests.
* diagnostics(agc): trace video draw chains
Track decoded video planes through recent render-target dependencies and report texture payload summaries, generations, blend state, and viewport data for targeted analysis.
Keep the trace flag, rectangle-skip visibility, and flip-bounded diagnostic state together in this commit.
* fix(agc): snapshot rotating video buffers per draw
Recognize registered decoded-video buffer addresses independently of tracing and bypass address-only upload and texture-content cache shortcuts for those ranges.
This preserves the texels associated with queued draws when the decoder later reuses a rotating guest buffer.
* fix(video): queue decoded frames and honor seek state
Start video decoding with playback, buffer decoded frames on a bounded worker queue, and distinguish pending data from end of stream instead of blocking guest polling.
Preserve pause state across jumps, seek audio and video decoders to the requested timestamp, offset reported times, and deliver the completion warning through the event callback ABI.
* fix(video): load replacement-backed sources through callbacks
Read replacement-backed sources through the guest open, size, offset-read, and close callbacks, materializing a temporary host file for decoding.
Fall back to the ordinary resolved path when the optional replacement interface declines a source, and clean up owned temporary files when sources or players are released.
* fix(video): report decoded stream metadata
Preserve display aspect ratio, color range, primaries, transfer characteristics, frame pitch, and crop information when reporting decoded video streams and frames.
Use the stream's fallback frame rate when its average rate is unavailable, and cover the extended ABI field layout with focused tests.
* fix(video): report extended audio stream format
Populate channel count and sample rate in extended stream details so clients configure decoded PCM output correctly. Add ABI coverage for the audio union layout and duration.
* fix(shader): preserve full LDS single-address offsets
Combine both encoded offset bytes for single-address data-share operations while retaining independent scaled offsets for paired forms. Apply the correction to both shader backends and add decoder and generated-module regression coverage.

Build context and user-config primitive state independently, merge optional hull-stage state, and select the correct output primitive source. Cover hull handling and derived versus shader-owned output primitives.
* fix(agc): emit native indirect register packets
Emit and parse native indirect context, shader, and user-config register packets. Patch native address and count fields without clobbering control bits, retain legacy packet compatibility, and apply flagged depth-size entries to the correct state.

Add canonical draw-state summaries with optional descriptor detail filters. Improve guest instruction sampling with thread selection and per-window accounting, and trace register-default handoff provenance.
* fix(video): publish cache identity for depth aliases
Reuse the exact sampled-texture content identity when a depth-backed image resolves successfully. Publish its sampler and write generation so later submissions avoid redundant guest-memory snapshots that the presenter would discard.

Read only the programmed pixel input controls and use identity mappings beyond that range. Share duplicate-location resolution between both shader backends.
Test input-count bounds, zero-input state, identity fallback, duplicate mappings, and location limits.
* chore(diagnostics): trace interpolant packet and draw mappings
Add opt-in packet fingerprints, register pairs, and consumed draw mappings through SHARPEMU_TRACE_AGC_INTERPOLANT_FLOW.

Record fault, protection, and lock timings under frame tracing. Separate tracker and image-cache activity. Prepare thread-local state before guest execution. Report cumulative measurements without changing memory protection or lock ownership.
* feat(gui): expose strict shader mode and enable it by default
Add the strict compute switch to global and per-game debug options. Stop on shader rejections unless skip mode is explicitly selected. Preserve disabled overrides and apply the saved choice at launch. Document the default and skip behavior.
* fix(shader): implement unsigned vector xor-add
Decode V_XAD_U32 and apply XOR followed by wrapping addition in Vulkan, Metal, and resource evaluation. Add tests for literal sources, overlapping destinations, and inactive execution lanes.
* fix(gpu): replace incompatible image backing types
Replace single-row image backings when a view requires a different dimensional type. Preserve cached subresources, current contents, and deferred release. Copy between 1D and 2D images through a GPU buffer. Add cache and binding regression tests.
* fix(shader): add thread-indexed local-memory reads
Decode the thread-indexed read instruction. Form each address from the low 16 bits of M0, the byte offset, and four times the lane index. Preserve inactive destination registers. Add Vulkan and Metal translation support and regression tests.
* test(stdio): synchronize concurrent file operations
Run blocking file operations on dedicated threads. Check that close and seek block before releasing the read. Join workers before cleanup and identify failed synchronization checkpoints.
* fix(cpu): read Linux diagnostic memory safely
Use process_vm_readv to read host memory outside the allocation tracker. Reject incomplete reads and test access across a protected page.
* fix(cpu): defer native callback allocation
Create the import callback thunk when it is first needed. Reject native execution outside an x64 process and declare that requirement in backend tests.
* fix(memory): use address-space protection granularity
Keep the native page-size requirement and let test address spaces declare their granularity. Use one host-memory backend for tracker allocation and queries. Keep the test fatal handler active through cleanup.
* test(cpu): isolate POSIX signal recovery state
Prevent signal recovery tests from overlapping other test collections. Restore the previous backend after each test.
* test(metal): resolve fixture buffer descriptors
Materialize buffer descriptors before compiling compute fixtures. Check the resolved formats and update the matching shader snapshots without changing expected device results.
* test(memory): require supported native page protection
Declare the 4 KiB host page requirement for image tracking and backing-view fault tests. Skip these tests on unsupported hosts without changing production checks.
* fix(memory): isolate write-tracker warm-up pages
Use a dedicated host mapping for protection warm-up. Release the mapping after removing its tracker entry. Check native page permissions in the tracker tests.
* fix(memory): track POSIX backing-view query state
Share view mapping and protection records across host memory queries. Preserve committed state for inaccessible pages and round partial-page changes to host pages. Update protection records without allocating during faults.
* test(memory): use valid portable guest ranges
Probe free addresses within the guest range instead of relying on fixed or host-selected addresses. Respect guest and host alignment. Allocate output storage independently of fixed guest image addresses.
* fix(memory): preserve execute permissions during writes
Request writable protection without execute permission for non-executable private memory. Add a regression check that rejects unnecessary executable protection. Restore the original protection after the write.
* fix(cpu): resolve Linux TLS through libpthread
Load Linux thread-local storage functions from libpthread.so.0. Resolve the native TLS lookup from the same library to support glibc versions before the libc merge. Keep macOS imports unchanged.
* fix(kernel): connect sockets without thread-pool waits
Use synchronous TCP connection handling for the blocking guest call. Remove the fixed task wait that could reject connections under thread-pool load. Add tests for occupied workers, refused connections, and descriptor lifetime.
* fix(gpu): prepare device memory and guard inactive loads
Keep active buffers resident and upload read-only device-address ranges before use. Preserve pending faults when the output buffer is full. Prevent inactive lanes from loading global memory.
* feat(gpu): trace device-address memory faults

Clamp each unsigned input to 16 bits. Pack the first input into the low half and the second input into the high half on Vulkan, Metal, and the resource evaluator.
* fix(memory): reject overlapping fixed allocations
Reject committed pages when an exact allocation shares a host reservation. Keep adjacent allocations valid and preserve existing memory regions.
* fix(kernel): implement AIO waits and correct array arguments
Return recorded completion states for single-request waits. Use the correct argument order for array waits and polls. Validate request IDs and guest memory accesses.
* fix(shader): implement scalar signed absolute value
Decode S_ABS_I32 and emit it on Vulkan and Metal. Preserve the minimum signed value and update the scalar condition flag. Match these results in resource evaluation.

Decode V_XOR3_B32 and combine all three inputs on Vulkan and Metal. Apply the same operation during resource evaluation.
* fix(shader): implement scalar bit clear
Decode S_BITSET0_B32 and clear the selected destination bit on Vulkan and Metal. Preserve the condition flag and retain the destination input for scalar bit updates.
* fix(gpu): keep depth export format from enabling pixel shaders
Use shader control flags to detect depth and coverage effects. Do not activate a pixel shader for a depth-only draw because an export format remains set.

Report whether a failed relocation target is readable and list its tracked memory regions. Keep the details under the existing data-rebind logging switch.
* feat(kernel): trace guest-tracked mutex self-locks

* fix(gui): add missing Azerbaijani option text
Add labels and descriptions for crash dumps, performance profiling, strict shader checks, and the performance display.
AjmModuleUnregister/AjmFinalize were pure no-ops (always returned success
without touching state); they now validate the context and actually remove
the codec registration / context entry, returning a real error when the
context is unknown. AjmModuleUnregister traces whether the codec was
actually registered, to help spot a title unregistering something it never
registered.
MaxCodecType was hardcoded to 25 based on known Sony codec ids, incorrectly
rejecting valid Gen5 codec types (e.g. 24). Registration is pure bookkeeping
(HashSet.Add); the only real constraint is that codecType must not overflow
the 32-bit instanceId it gets packed into, i.e. codecType < 2^18. Named the
instanceId bit-packing constants (InstanceIdSlotBits/InstanceIdSlotMask) so
the four call sites that used to hardcode 14/0x3FFF independently can't
drift out of sync, and MaxCodecType's formula is self-evident.
Accept sceAcmBatchInitialize/InitializeLite/Start/StartMultiple/Process as
successful no-ops -- the emulator runs no ACM DSP jobs, but Scream's workers
trap on int 0x41/0x42 asserts whenever a submission call reports failure.
Accept sceAudioOut2MasteringInit/Set3DLatency as no-ops -- the host mixer
has no mastering/object pipeline to tune, but returning failure makes
titles tear down their whole ACM context and abort audio arena bring-up.
Tested on Ghost of Yotei (PPSA26344): sceAudioOut2MasteringInit/Set3DLatency
unresolved-import warnings go from 2 to 0, unblocking 5 audio-related guest
threads that never spawned before (MovieDecoder, snd_stream_parsing_thread,
snd_stream_reader_thread, Psn, NCA::PumpThread), watchdog stall errors from
1 to 0. This alone gets the title past its Scream audio-init stall into
further boot, but it still hits an unrelated infinite retry loop in
sceVideoOutGetFlipStatus shortly after -- fixed by the separate
videoout-agc-hle-misc change; combined, the title renders and presents a
real GPU frame.
Regression-checked on Demon's Souls, Astro Bot, Outer Wilds, Cult of the
Lamb, Ghost of Tsushima, GTA, Minecraft, Quake: 0 calls to any export
touched by this change on any of them, byte-for-byte identical to
upstream/main.
* [VideoOut/Vulkan] Fix boot deadlock, writeback stall, and presentation bugs
- Presenter thread now starts on the compute dispatch path too, fixing
a boot deadlock when a title's first GPU work is compute (Ghost of
Yotei G-Buffer clear).
- Guest render-target format swaps between sibling pixel formats now
reinterpret in place instead of recreating blank, preserving
GPU-written content.
- Vectorized the guest-buffer writeback scan (equal-byte skip + coarse
per-page pre-check), fixing multi-second stalls on fragmented buffers
that starved JobWorker completion signals.
- _presentedSequence now advances on every Render() early-return path,
fixing an unthrottled busy loop on stale/dropped presentations.
* Remove unnecessary Silk.NET.Windowing dependency
- Fixed guest mappings now go through a granule-aware allocator so
adjacent PS5 16 KiB pages sharing a 64 KiB Windows allocation
granule no longer collide and fail.
- TryBackFixedRange routes free/reserved gaps through the same
granule-safe path, fixing strays that stranded the rest of a granule.
- NORMAL pthread mutex self-relock reverted to real EDEADLK instead of
silent compatibility recursion, which was starving other threads.
- TryResolveMutexState now checks the handle-keyed lookup before
falling through to "not found" on a fresh, never-cached address.
Three defects found while bringing up a PS5 title. None are title-specific.
SPI_SHADER_PGM_LO_GS / HI_GS were 0x8A/0x8B, which are actually
SPI_SHADER_PGM_RSRC1/RSRC2_GS. Reading them as an address produced a
58-bit value (observed live: 0x30004622C008300). The correct offsets are
0x88/0x89, consistent with SPI_SHADER_PGM_CHKSUM_GS = 0x80 and
SPI_SHADER_PGM_LO_ES = 0xC8 already in the table.
Draw translation dropped any RECT_LIST draw whose vertex program exported
no parameters while the pixel shader had interpolated inputs. A
disposition census over a real run measured this deleting ~620 of every
5000 draws (12%). Rect lists are what AMD drivers emit for clears, blits
and resolves, so the guard was deleting clears and leaving previous frame
contents on screen as trails. Rendering a draw whose interpolants are
undefined is strictly better than deleting it.
sceAgcDcbDrawIndexIndirectMultiGetSize was unimplemented while
sceAgcDcbDrawIndexIndirectMulti emits an eight-dword packet. A title that
sizes its command buffer from the missing export under-reserves by three
dwords. NID derived with Ps5Nid.Compute, which reproduces the committed
NIDs of the neighbouring exports.
Tests: AgcContextRegisterTests and AgcShaderStageRegisterTests drive real
PM4 packets through sceAgcDriverSubmitDcb and assert what the parser
retained for the context and SH register dictionaries, via two new
internal accessors; neither dictionary had any test surface, which is why
register questions previously cost five-minute game runs.
* VideoOut: track guest-flip FPS and label load/stall gaps
Headline FPS follows VideoOut submit cadence rather than host presents, and long gaps show LOAD/STALL instead of a stale multi-second MS average.
* Metal: skip waitUntilCompleted when the command buffer is already Completed
Tiny write-back batches often finish before the wait; checking status avoids redundant ordered-queue round-trips.
* Metal: opt-in long-edge drawable cap via SHARPEMU_METAL_CAP_DRAWABLE
Default presentation resolution is unchanged; set SHARPEMU_METAL_CAP_DRAWABLE=1 to cap the drawable long edge at 1920.
* Pad: implement scePadGetTriggerEffectState under its own NID
NID znaWI0gpuo8 was mapped to sceUserServiceGetUserName as a "title-captured
alias". It is not that symbol. Recomputing the NID of every catalogued name
(base64 of the reversed first eight sha1 bytes of name+salt) resolves
znaWI0gpuo8 to scePadGetTriggerEffectState, and sceUserServiceGetUserName
hashes to 1xxcMiGu2fo instead. Auditing all 1087 export declarations the same
way found this to be the only NID whose declared name is wrong.
The consequence was not a missing export but a wrong one: the user-service
handler rejected the pad's arguments and returned
SCE_USER_SERVICE_ERROR_INVALID_PARAMETER about eighteen thousand times per
run in PPSA10112, so every poll fell back to a cached button bitmask. It
also hid the calls from every search for pad activity, which is why this
title was believed never to touch scePad at all.
The state size is taken from the caller's own frame rather than assumed: the
guest points the out-param at rbp-0x30 and stores its stack cookie at
rbp-0x28, leaving eight bytes for the state. Writing the sixteen the frame
superficially suggests would land on the cookie and fail the guest's stack
check - the same failure this codebase has already hit three times from
oversized HLE writes - so the test pins the size by asserting the cookie
survives.
No host pad exposes DualSense adaptive-trigger feedback, so the neutral
all-zero state is reported as success, which lets the caller take its normal
path instead of the fallback.
* Apply SDWA ABS/NEG as float sign-bit, not integer, modifiers
SDWA's ABS and NEG source modifiers are floating-point sign-bit
operations on GCN: ABS clears the sign bit, NEG flips it. We applied
them as integer operations instead - SAbs, and a two's-complement
negate of the raw bit pattern. That turns 1.0 into -4.0 and -3.0 into
1.5.
UE4 compiles the final line of DrawRectangle, OutPosition.xy *=
float2(1,-1), into a single V_MOV_B32 with SDWA NEG, so every UE
fullscreen pass had its clip-space Y silently skewed. The canonical
fullscreen triangle (1,-1) (-3,-1) (1,3) became (1,-4) (-3,-4) (1,1.5),
which covers 6/11 of the viewport instead of all of it.
That reproduces the measured defect exactly, on four independent
quantities: hypotenuse slope 8/11, crossings of y=+1 and y=-1 at
x=+7/11 and x=-9/11, and covered area 6/11 = 54.55% of the 2304x1296
viewport. It also explains why the edge was resolution-independent and
identical across six unrelated shaders - it is the same instruction in
every one of them.
The distinguishing evidence is the transform's fixed point. A wrong
scale would hold NDC -1 in x and +1 in y; the observed transform holds
the opposite corner in both. Independently, and using only the measured
line rather than any assumed vertex position: a wrong multiplier alone
leaves a residual of -18 whatever the multiplier, and a wrong addend
alone forces slope 1, not 8/11. Both terms had to be wrong at once,
which only a Y-only sign-bit corruption produces.
Float instructions are unaffected: GetFloatSource passes
applySdwaIntegerModifiers: false and applies its own modifiers, so this
path only ever fed raw-source reads - where the hardware behaviour is
the sign-bit one regardless of the opcode being a bit-move.
The sign bit is selected by the SDWA source-select width so a 16-bit
select flips bit 15 rather than bit 31.
Verified: emitted SPIR-V for the same shader changes from
OpISub %uint %uint_0 %2147 to OpBitwiseXor %uint %2147 %uint_2147483648;
25-program synthetic conformance gate passes; 805 tests green; three
100-110s live runs with no crashes and no new shader failures. The
end-to-end pixel re-measurement is NOT yet closed - see task #26.
* gpu: size single-channel 16-bit and two-channel 8-bit formats
GetFormatCompatibilityClass listed only R16Sfloat in the 16-bit class, so
GetVulkanImageByteCount computed zero bytes for R16Unorm, R16SNorm, R16Uint,
R16Sint and the R8G8 family. UploadGuestImageInitialData treats a zero
expected size as an incompatible upload and drops it, which leaves the
texture blank for the rest of the run rather than failing loudly.
Silent Hill uploads R16Unorm at 144x81, 240x135, 256x256, 512x512 and
1024x1024, and every one was rejected: the guest supplied exactly
width*height*2 bytes each time (23328 for 144x81) against an expected zero.
Also adds R8SNorm to the 8-bit class, which was missing for the same reason.
* Vulkan: enable textureCompressionBC when the device supports it
Guest BC1–BC7 textures can be sampled directly when the feature is available; warn when it is not.
* Share one guest image across sRGB/UNORM aliases
Ported from origin/fix/view-compatible-guest-images 7fb8fdf.
Rendering as sRGB and ImageLoad/Store-ing as UNORM at the same guest
address are the same surface accessed through different number formats.
Recreating the guest image per number format ping-pongs content between
two VkImages and loses the rendered pixels on every transition; the
mutable-format image now accepts the counterpart identity and serves it
through alias views. The commit names AvPlayer movie copies as the
pattern that needs this.
Adapted for this base: GetOrCreateGuestImage has since grown resolution
scaling and 3D/array support, so the alias accept is folded into the
current predicate (LogicalWidth/LogicalHeight/LogicalDepth/Type) rather
than the old Width/Height pair, and the storage-counterpart widening is
placed before the physical-dimension computation. The helper functions it
relies on (GetStorageImageFormat, IsCompatibleViewFormat) already existed.
* fix(gpu): one vertex attribute per guest stream view
The scalar evaluator gave every buffer_load_format instruction its own
attribute location. Two things multiply those: the CFG walk visits one
instruction on several paths, and an uber vertex shader fetches the same
stream from every material branch. UE's larger shaders reached 56 bindings
from 8 distinct views, and one reached 701 from 5.
Metal caps a vertex function at 31 attributes, so MoltenVK failed the MSL
compile with "'attribute' attribute parameter is out of bounds" and the
surrounding vkCreateGraphicsPipelines returned ErrorInitializationFailed.
Every draw using those pipelines was dropped, which is why Silent Hill:
The Short Message rendered a black scene. The vertex buffer count drove
Metal's buffer indices out of range too, giving the companion
"cannot reserve 'buffer' resource location at index 0" failures.
Key attributes by the guest stream view they read - absolute element
address, record stride and format - and alias every other fetch that
resolves to the same view onto that binding, so both translators map
those instruction PCs to one input variable. On PPSA10112 this takes the
worst shader from 56 attributes to 8 and pipeline failures from 840 to 0.
* AGC: deliver compute-queue completion events at the queue fence
sceAgcDriverSubmitAcb submissions never produced a completion interrupt.
NotifySubmittedDcbCompleted returned early for anything that was not the
graphics queue, so an ACB reaching its ordered-queue fence published
nothing. UE 4.27's dynamic-resolution GPU-timing heuristic parks the game
thread on exactly that interrupt, so the render side never advanced and
Silent Hill: The Short Message deadlocked after its first frame.
Give every queue a CompletionEventId: 0 for graphics (what it already
published) and the owner handle from sceAgcDriverSubmitAcb rdi for a
compute queue, which is the same value the guest passes to
sceAgcDriverAddEqEvent. Publish under that ident from the existing fence
point, which both PumpSubmittedQueue and ResumeSuspendedDcb already reach
only after the submission is fully parsed.
Delivery is synchronous on the ordered guest-action queue rather than on a
ThreadPool hop with a sleep. That action runs after the logical queue has
flushed and waited for its latest fence, which is the moment hardware
would raise end-of-pipe. Deferring past it can only make the interrupt
late and reorder it against registration changes.
Gating: the per-queue completion event is unconditional, because
completion interrupts do fire on real hardware and because delivery is
registration-gated -- TriggerRegisteredEvents only queues onto equeues
that registered this exact (ident, graphics filter) pair, and
sceAgcDriverAddEqEvent is the only producer of graphics registrations. A
title that never registers its ACB owner handle observes no change.
SHARPEMU_AGC_SUBMIT_COMPLETION_EVENT is left to gate only the broad
ident-ignoring fan-out (TriggerRegisteredEventsDistinct), which is a
compatibility guess rather than hardware behavior; it also stays scoped to
the graphics queue where it was measured, so enabling the flag does not
newly fan out across compute queues.
* fix(gpu): reflect guest CPU writes into large and render-target-aliased images
Ports the still-applicable half of the archived fork's stale-texture fix
(a42ccae) onto current main. Silent Hill: The Short Message (PPSA10112)
shows both faces: black title-screen UI (glyph atlas frozen at its first
upload) and stale/garbage rows on the brightness screen (a 3840x2160 UI
sheet whose backing bytes were never re-read).
1. Write tracking is armed under a byte budget, not a resolution cap.
GetOrCreateGuestImage armed GuestImageWriteTracker only when
target.Width <= 1920 && target.Height <= 1080. Silent Hill renders at
3840x2160, so every one of its render targets was excluded from
CPU-write tracking and no guest rewrite of one could ever invalidate
it: SyncCpuWrittenGuestImages (the flip / ACQUIRE_MEM re-upload path)
only ever visits ranges the tracker armed.
The cap presumably existed as a perf guard, but resolution is the
wrong proxy for the cost. Arming is one mprotect over the range, and
the fault handler unprotects the whole range on the first store, so a
write burst costs one fault regardless of size. What actually scales
with the surface is the dirty re-upload: one byte[byteCount]
allocation plus a full guest-memory read per dirty flip. So the guard
is now a byte budget, set equal to the 128 MiB limit that
SyncCpuWrittenGuestImages itself enforces before re-uploading. Above
that, arming can only cost faults; it can never produce a re-upload.
That is generous for 4K (RGBA8 32 MiB, RGBA16F 63 MiB, RGBA32F
127 MiB all fit) while still excluding volume textures that a
resolution cap could not see at all (512^3 RGBA8 is 512 MiB behind a
"512x512" surface).
Both sites now also arm the exact extent recorded in
_guestImageExtents (GetTextureByteCount) instead of
Width*Height*depth*GetTextureBytesPerPixel, so the armed range and
the range the sync path reads back are the same bytes; the old
expression over-counted block-compressed and unknown formats.
2. The CPU-texture refresh path no longer gates on IsCpuBacked alone.
TryCreateCpuTextureRefreshResource bailed on !guestImage.IsCpuBacked.
That flag is a latch: it flips false the first time an address is
used as a render target and never flips back. A surface that was
rendered into once and is afterwards rewritten by the guest CPU was
therefore frozen at its last GPU content forever, even when the parse
thread had already shipped fresh texels for it.
The gate is replaced by ShouldRefreshGuestImageFromCpu: CPU-backed,
or the parse-time write generation is above zero and differs from the
generation recorded by the last upload. Keeping the positive-
generation requirement preserves the pure GPU-feedback case (render
into an image, then sample it) that IsCpuBacked used to protect: such
a surface is now tracked (change 1) but never CPU-written, so its
generation stays zero and its live image is left alone. This matters
more than it did in the fork, precisely because change 1 arms
tracking on far more render targets. Dropping the gate outright, as
the fork did, would let a target sampled under a format tag that the
availability map does not match be overwritten once with whatever
sits in guest memory.
The existing content fingerprint still suppresses redundant uploads,
and MarkSampledImagesInitialized records the uploaded generation, so
a rewritten surface re-uploads exactly once per guest write burst.
Not ported: the fork's third part added a PeekDirty guard to the
parse-time snapshot fast path in AgcExports. It is superseded. That path
now calls IsGuestImageUploadKnown, which already compares
_cpuBackedUploadGenerations against the tracker's write generation - a
monotonic value that survives another owner consuming the dirty flag,
unlike PeekDirty, which both EvictDirtyCachedTextures and
SyncCpuWrittenGuestImages clear. Guest images with no generation entry
are covered instead by SyncCpuWrittenGuestImages. Adding a non-consuming
PeekDirty there would also make every draw between a CPU write and the
next flip fall through to a full texel re-read of the surface (33 MiB
for a 4K sheet), since Track re-arms without clearing the dirty flag.
The fork's promotion-path Track ("vulkan.cpu-backed-image") is likewise
superseded: AgcExports already arms every sampled texture's backing
extent as "agc.decoded-texture" before reading its texels.
Both decisions are extracted as pure internal predicates so they can be
unit-tested; the Vulkan device code around them needs a real device.
* Kernel: correct equeue event delivery and waiter lifetime
Ports the event-queue rework from the archived silent-hill-minimal branch
(968e9606, 9e3abb12, 2be9cfbf, f157a115) onto current upstream. The equeue
implementation had not been touched upstream since that branch forked, so
none of it had landed.
Behaviour fixed:
- Per-waiter event reservation. A blocked waiter used to wake on "the queue
has any pending event" (TryWake => HasPendingEvents) and then re-read the
queue on resume, so a woken waiter could find the event already drained by
another waiter and park again with the wake consumed. Events are now
reserved to the waiter they are delivered to.
- Level-triggered events are preserved instead of being cleared by an
unrelated read; only events that declare clear-on-read reset their trigger
state.
- Queued interrupts are bound to the registration generation that produced
them, so an event registered after a queue was reused cannot consume an
interrupt raised for the previous registration.
- Deleting an equeue now terminates its waiters instead of leaving them
blocked on a handle that no longer resolves.
- sceKernelTriggerUserEvent stores its third argument in the event's udata
(0x18) rather than its data word (0x10). The guest reads it back with
sceKernelGetEventUserData, which loads 0x18, so every triggered user event
previously read back as 0. This matches the reference behaviour in shadPS4,
where TriggerEvent takes udata and sceKernelGetEventUserData returns
ev->udata. The upstream test asserting the data word is updated, since it
encoded the inconsistency rather than the ABI.
KernelPthreadState gains TryGetCurrentThreadIdentity and a new
KernelSyncTraceFormatter carries the shared, opt-in diagnostic formatting the
ported code calls; both are gated behind the existing trace flag and do no
work when it is off.
Tests: 662 pass, 0 fail (SharpEmu.Libs.Tests 588 -> 598).
* Implement VOP3 0x149 V_BFE_I32 and 0x36A V_CVT_PKRTZ_F16_F32
PPSA10112 dropped three shaders per run on two unimplemented VOP3
opcodes. The translator fails a whole shader on an opcode it does not
know, so each one costs a dropped draw rather than wrong pixels.
0x149 sits between 0x148 V_BFE_U32 and 0x14A V_BFI_B32, and 0x36A
between 0x369 V_CVT_PKNORM_U16_F32 and 0x36D V_ADD3_U32; the
surrounding table entries already match the canonical map densely on
both sides of each gap. V_CVT_PKRTZ_F16_F32 needed no emitter - it was
already implemented for the VOP2 form at 0x2F and its VOP3 alias at
0x12F, and only the VOP3-only opcode number was missing.
V_BFE_I32 mirrors its unsigned sibling, masking offset and width to 5
bits, and differs only in extracting through a signed type so the field
sign-extends. GCN defines width 0 as returning 0 where SPIR-V leaves a
zero Count unspecified; VBfeU32 has the same gap, so this matches it
deliberately rather than diverging - fix both together if it matters.
Also widen ReportGuestPointerSplit, which filtered to an incoming value
of exactly 1. The crash being hunted leaves 0x0000007000000000, whose
low dword is 0, so the one detector built to catch this bug class could
never have reported it.
Verified: unsupported-opcode errors 3-4 per run -> 0, over a 130s run
that survives to the same stage. Metal translator still lacks VBfeI32;
Vulkan/MoltenVK is the macOS path so it is a divergence, not a blocker.
* AGC: retain active label producer records
Ported from the archived silent-hill-minimal branch (274ccfdf).
RegisterLabelProducer bounded its history with RemoveRange(0, 1024) once it
reached 4096 entries, which evicts the oldest records regardless of whether
their label write has completed. Those records are not a diagnostic cache:
a suspended DCB resolves its wait_reg_mem by finding the producer that will
write the watched label. Dropping an active record hides an earlier
same-submission label write, so a legitimate in-stream fence suspends
forever and the graphics queue stops.
Compact only completed history, and let the list exceed the soft bound when
every record is still active — correctness over a diagnostic limit.
Two hardening changes over the ported version, because a suspended queue is
exactly when every record is active:
- compaction is a single order-preserving pass instead of repeated RemoveAt,
which would shift the tail per eviction (quadratic) while the label gate is
held;
- when a pass frees nothing the bound is raised to twice the current count, so
registration does not rescan the whole list on every subsequent add, and it
is reset once compaction can make progress again.
Tests: 664 pass, 0 fail (SharpEmu.Libs.Tests 598 -> 600).
* AGC: keep produced label values a suspended wait still needs
GpuWaitRegistry.RecordProduced dropped the entire produced-value table once it
reached 8192 entries:
if (_lastProduced.Count >= 8192) { _lastProduced.Clear(); }
Those entries are release state, not a cache. CollectDeadlockBroken is the only
way out for a DCB suspended on a WAIT_REG_MEM whose label the guest has since
recycled for other data: it replays the value a real producer already wrote to
that label. Clearing the table wholesale erases exactly the records live waiters
depend on, so every such waiter is stranded permanently — the suspended graphics
queue never resumes, and with it the render thread and the whole engine thread
graph park.
That is what Silent Hill (PPSA10112) hits. Its final unsatisfied waits watch
labels holding guest allocator metadata (each reads a pointer into its own
region rather than the expected 1), i.e. recycled memory, which is precisely
the case the deadlock breaker exists to handle — yet agc.deadlock_break fires 0
times across a run with 490 wait suspensions and 1068 successful release_mem
writes, because the producing values had already been cleared.
Prune only values no registered waiter is watching, and let the table exceed the
soft bound while they are all watched. Same reasoning as the label-producer
history in the preceding commit: correctness of synchronization state takes
precedence over a diagnostic bound.
Tests: 666 pass, 0 fail. The regression test fails against the previous
wholesale Clear() and passes with the prune, verified by reverting the fix.
* Correct VOP3 0x36A: V_CVT_PK_U16_U32, not V_CVT_PKRTZ_F16_F32
a2d186e mapped 0x36A to V_CVT_PKRTZ_F16_F32 on the strength of a gap in
our own opcode table. That was wrong, and wrong in the worst available
way: an emitter for V_CVT_PKRTZ_F16_F32 already existed, so instead of
failing loudly like an unknown opcode, the mapping would have emitted
float-pack semantics for an integer-pack instruction and produced
silently incorrect results.
LLVM is unambiguous:
defm V_CVT_PK_U16_U32 : VOP3Only_Real_gfx10<0x36a>;
defm V_CVT_PKRTZ_F16_F32 : VOP2_Real_gfx6_gfx7_gfx10<0x02f>;
so on Gen5 the float pack is VOP2 0x2F with VOP3 alias 0x12F - both of
which our table already had - and there is no VOP3-only encoding of it
to add. 0x36A sits with the other integer/normalised pack conversions
at 0x368/0x369/0x36B.
silent-hill-minimal-rebased had this right all along.
The V_BFE_I32 half of a2d186e stands: LLVM confirms 0x149, and that
branch maps it identically.
Lesson, since I had just warned someone else about exactly this: a gap
in a table is evidence about numbering, not about identity. Inference
from neighbouring entries is fine for narrowing candidates and worth
nothing as a conclusion - especially when a plausible emitter already
exists to swallow the mistake quietly.
* AGC: report release-label writes that never reach guest memory
Both release_mem handlers recorded the produced label value only on success:
if (wroteData && dataSelection is 1 or 2) GpuWaitRegistry.RecordProduced(...)
with no else. A failed write is not benign here. That packet is the producer a
suspended WAIT_REG_MEM is waiting for, so when it fails the label is neither
written nor recorded, CollectDeadlockBroken has no value to replay, and the
graphics queue stays suspended forever — the render thread and the engine
thread graph park behind it with nothing in the log to say why.
Measured on Silent Hill (PPSA10112): the fatal AccessViolation lands exactly
here, on the presenter thread, in ApplySubmittedReleaseMem's label write into a
protected guest page. The faulting variant kills the process; the
returns-false variant wedges the GPU silently. Only the first was ever visible.
Report the failure (rate-limited: first 16, then powers of two) instead of
dropping it. This does not fix the underlying write failure — it makes a
permanently suspended queue diagnosable rather than silent.
Tests: 666 pass, 0 fail.
* CPU: gate periodic import logs and fast-path memcpy/memmove leaves
SHARPEMU_LOG_IMPORT_PERIODIC=1 re-enables periodic Import# tracing. memcpy/memmove use a thin TryCopy leaf that skips register marshalling.
* Ampr: cooked-id index preload and host FD LRU cache
Preload the app0 APR index during bind and bound the open host-file cache so streaming reads stay responsive under large title archives.
* Vulkan: abandon timed-out guest fences without blocking later frames
Move fence-timeout submissions out of the blocking queue, keep GPU objects alive until the fence signals, and retire them from an abandoned list so one hung dispatch cannot re-block capacity waits.
* AGC: follow command-buffer branches across arena switches
Implement sceAgcCbBranch and walk INDIRECT_BUFFER so submissions that continue in a linked buffer keep their flip and end-of-frame labels.
Ports the event-queue rework from the archived silent-hill-minimal branch
(968e9606, 9e3abb12, 2be9cfbf, f157a115) onto current upstream. The equeue
implementation had not been touched upstream since that branch forked, so
none of it had landed.
Behaviour fixed:
- Per-waiter event reservation. A blocked waiter used to wake on "the queue
has any pending event" (TryWake => HasPendingEvents) and then re-read the
queue on resume, so a woken waiter could find the event already drained by
another waiter and park again with the wake consumed. Events are now
reserved to the waiter they are delivered to.
- Level-triggered events are preserved instead of being cleared by an
unrelated read; only events that declare clear-on-read reset their trigger
state.
- Queued interrupts are bound to the registration generation that produced
them, so an event registered after a queue was reused cannot consume an
interrupt raised for the previous registration.
- Deleting an equeue now terminates its waiters instead of leaving them
blocked on a handle that no longer resolves.
- sceKernelTriggerUserEvent stores its third argument in the event's udata
(0x18) rather than its data word (0x10). The guest reads it back with
sceKernelGetEventUserData, which loads 0x18, so every triggered user event
previously read back as 0. This matches the reference behaviour in shadPS4,
where TriggerEvent takes udata and sceKernelGetEventUserData returns
ev->udata. The upstream test asserting the data word is updated, since it
encoded the inconsistency rather than the ABI.
KernelPthreadState gains TryGetCurrentThreadIdentity and a new
KernelSyncTraceFormatter carries the shared, opt-in diagnostic formatting the
ported code calls; both are gated behind the existing trace flag and do no
work when it is off.
Tests: 662 pass, 0 fail (SharpEmu.Libs.Tests 588 -> 598).
Ports the still-applicable half of the archived fork's stale-texture fix
(a42ccae) onto current main. Silent Hill: The Short Message (PPSA10112)
shows both faces: black title-screen UI (glyph atlas frozen at its first
upload) and stale/garbage rows on the brightness screen (a 3840x2160 UI
sheet whose backing bytes were never re-read).
1. Write tracking is armed under a byte budget, not a resolution cap.
GetOrCreateGuestImage armed GuestImageWriteTracker only when
target.Width <= 1920 && target.Height <= 1080. Silent Hill renders at
3840x2160, so every one of its render targets was excluded from
CPU-write tracking and no guest rewrite of one could ever invalidate
it: SyncCpuWrittenGuestImages (the flip / ACQUIRE_MEM re-upload path)
only ever visits ranges the tracker armed.
The cap presumably existed as a perf guard, but resolution is the
wrong proxy for the cost. Arming is one mprotect over the range, and
the fault handler unprotects the whole range on the first store, so a
write burst costs one fault regardless of size. What actually scales
with the surface is the dirty re-upload: one byte[byteCount]
allocation plus a full guest-memory read per dirty flip. So the guard
is now a byte budget, set equal to the 128 MiB limit that
SyncCpuWrittenGuestImages itself enforces before re-uploading. Above
that, arming can only cost faults; it can never produce a re-upload.
That is generous for 4K (RGBA8 32 MiB, RGBA16F 63 MiB, RGBA32F
127 MiB all fit) while still excluding volume textures that a
resolution cap could not see at all (512^3 RGBA8 is 512 MiB behind a
"512x512" surface).
Both sites now also arm the exact extent recorded in
_guestImageExtents (GetTextureByteCount) instead of
Width*Height*depth*GetTextureBytesPerPixel, so the armed range and
the range the sync path reads back are the same bytes; the old
expression over-counted block-compressed and unknown formats.
2. The CPU-texture refresh path no longer gates on IsCpuBacked alone.
TryCreateCpuTextureRefreshResource bailed on !guestImage.IsCpuBacked.
That flag is a latch: it flips false the first time an address is
used as a render target and never flips back. A surface that was
rendered into once and is afterwards rewritten by the guest CPU was
therefore frozen at its last GPU content forever, even when the parse
thread had already shipped fresh texels for it.
The gate is replaced by ShouldRefreshGuestImageFromCpu: CPU-backed,
or the parse-time write generation is above zero and differs from the
generation recorded by the last upload. Keeping the positive-
generation requirement preserves the pure GPU-feedback case (render
into an image, then sample it) that IsCpuBacked used to protect: such
a surface is now tracked (change 1) but never CPU-written, so its
generation stays zero and its live image is left alone. This matters
more than it did in the fork, precisely because change 1 arms
tracking on far more render targets. Dropping the gate outright, as
the fork did, would let a target sampled under a format tag that the
availability map does not match be overwritten once with whatever
sits in guest memory.
The existing content fingerprint still suppresses redundant uploads,
and MarkSampledImagesInitialized records the uploaded generation, so
a rewritten surface re-uploads exactly once per guest write burst.
Not ported: the fork's third part added a PeekDirty guard to the
parse-time snapshot fast path in AgcExports. It is superseded. That path
now calls IsGuestImageUploadKnown, which already compares
_cpuBackedUploadGenerations against the tracker's write generation - a
monotonic value that survives another owner consuming the dirty flag,
unlike PeekDirty, which both EvictDirtyCachedTextures and
SyncCpuWrittenGuestImages clear. Guest images with no generation entry
are covered instead by SyncCpuWrittenGuestImages. Adding a non-consuming
PeekDirty there would also make every draw between a CPU write and the
next flip fall through to a full texel re-read of the surface (33 MiB
for a 4K sheet), since Track re-arms without clearing the dirty flag.
The fork's promotion-path Track ("vulkan.cpu-backed-image") is likewise
superseded: AgcExports already arms every sampled texture's backing
extent as "agc.decoded-texture" before reading its texels.
Both decisions are extracted as pure internal predicates so they can be
unit-tested; the Vulkan device code around them needs a real device.
sceAgcDriverSubmitAcb submissions never produced a completion interrupt.
NotifySubmittedDcbCompleted returned early for anything that was not the
graphics queue, so an ACB reaching its ordered-queue fence published
nothing. UE 4.27's dynamic-resolution GPU-timing heuristic parks the game
thread on exactly that interrupt, so the render side never advanced and
Silent Hill: The Short Message deadlocked after its first frame.
Give every queue a CompletionEventId: 0 for graphics (what it already
published) and the owner handle from sceAgcDriverSubmitAcb rdi for a
compute queue, which is the same value the guest passes to
sceAgcDriverAddEqEvent. Publish under that ident from the existing fence
point, which both PumpSubmittedQueue and ResumeSuspendedDcb already reach
only after the submission is fully parsed.
Delivery is synchronous on the ordered guest-action queue rather than on a
ThreadPool hop with a sleep. That action runs after the logical queue has
flushed and waited for its latest fence, which is the moment hardware
would raise end-of-pipe. Deferring past it can only make the interrupt
late and reorder it against registration changes.
Gating: the per-queue completion event is unconditional, because
completion interrupts do fire on real hardware and because delivery is
registration-gated -- TriggerRegisteredEvents only queues onto equeues
that registered this exact (ident, graphics filter) pair, and
sceAgcDriverAddEqEvent is the only producer of graphics registrations. A
title that never registers its ACB owner handle observes no change.
SHARPEMU_AGC_SUBMIT_COMPLETION_EVENT is left to gate only the broad
ident-ignoring fan-out (TriggerRegisteredEventsDistinct), which is a
compatibility guess rather than hardware behavior; it also stays scoped to
the graphics queue where it was measured, so enabling the flag does not
newly fan out across compute queues.
The scalar evaluator gave every buffer_load_format instruction its own
attribute location. Two things multiply those: the CFG walk visits one
instruction on several paths, and an uber vertex shader fetches the same
stream from every material branch. UE's larger shaders reached 56 bindings
from 8 distinct views, and one reached 701 from 5.
Metal caps a vertex function at 31 attributes, so MoltenVK failed the MSL
compile with "'attribute' attribute parameter is out of bounds" and the
surrounding vkCreateGraphicsPipelines returned ErrorInitializationFailed.
Every draw using those pipelines was dropped, which is why Silent Hill:
The Short Message rendered a black scene. The vertex buffer count drove
Metal's buffer indices out of range too, giving the companion
"cannot reserve 'buffer' resource location at index 0" failures.
Key attributes by the guest stream view they read - absolute element
address, record stride and format - and alias every other fetch that
resolves to the same view onto that binding, so both translators map
those instruction PCs to one input variable. On PPSA10112 this takes the
worst shader from 56 attributes to 8 and pipeline failures from 840 to 0.
Ported from origin/fix/view-compatible-guest-images 7fb8fdf.
Rendering as sRGB and ImageLoad/Store-ing as UNORM at the same guest
address are the same surface accessed through different number formats.
Recreating the guest image per number format ping-pongs content between
two VkImages and loses the rendered pixels on every transition; the
mutable-format image now accepts the counterpart identity and serves it
through alias views. The commit names AvPlayer movie copies as the
pattern that needs this.
Adapted for this base: GetOrCreateGuestImage has since grown resolution
scaling and 3D/array support, so the alias accept is folded into the
current predicate (LogicalWidth/LogicalHeight/LogicalDepth/Type) rather
than the old Width/Height pair, and the storage-counterpart widening is
placed before the physical-dimension computation. The helper functions it
relies on (GetStorageImageFormat, IsCompatibleViewFormat) already existed.
NID znaWI0gpuo8 was mapped to sceUserServiceGetUserName as a "title-captured
alias". It is not that symbol. Recomputing the NID of every catalogued name
(base64 of the reversed first eight sha1 bytes of name+salt) resolves
znaWI0gpuo8 to scePadGetTriggerEffectState, and sceUserServiceGetUserName
hashes to 1xxcMiGu2fo instead. Auditing all 1087 export declarations the same
way found this to be the only NID whose declared name is wrong.
The consequence was not a missing export but a wrong one: the user-service
handler rejected the pad's arguments and returned
SCE_USER_SERVICE_ERROR_INVALID_PARAMETER about eighteen thousand times per
run in PPSA10112, so every poll fell back to a cached button bitmask. It
also hid the calls from every search for pad activity, which is why this
title was believed never to touch scePad at all.
The state size is taken from the caller's own frame rather than assumed: the
guest points the out-param at rbp-0x30 and stores its stack cookie at
rbp-0x28, leaving eight bytes for the state. Writing the sixteen the frame
superficially suggests would land on the cookie and fail the guest's stack
check - the same failure this codebase has already hit three times from
oversized HLE writes - so the test pins the size by asserting the cookie
survives.
No host pad exposes DualSense adaptive-trigger feedback, so the neutral
all-zero state is reported as success, which lets the caller take its normal
path instead of the fallback.

with a stateful NLayer helper so menu music is not silent.
* fix(agc): map PS interpolants via SPI_PS_INPUT_CNTL semantics

it in the graphics shader cache key.
* fix(agc): rect-list/NGG strips, Index8 expand, and GE_INDX_OFFSET

* diag(gpu): log guest-queue backlog breakdown under backpressure
Rate-limit top work types and ordered debugName prefixes when the Vulkan guest work queue stalls, so North Yankton logs show acquire/label vs draw traffic instead of only VulkanOrderedGuestAction.
* perf(agc): coalesce acquire flushes and batch non-DMA label wakes
Flush pending ACQUIRE_MEM invalidation at draw/dispatch/dma/flip boundaries instead of before every packet, and complete release/write-data producers in the same ordered action so load paths enqueue far fewer VulkanOrderedGuestAction items.
* perf(gpu): wait for ordered-action fences and keep draining sync
On Windows/Linux, block briefly for queue-visibility fences instead of deferring the whole logical queue for the tick. Prefer ordered sync/flip heads under backlog pressure, and keep macOS non-blocking defer behavior.
* perf(gpu): raise sync-item ceiling above payload guest-work cap
Apply SHARPEMU_PENDING_GUEST_WORK_ITEMS mainly to compute/draw/image payload work, and allow a higher SHARPEMU_PENDING_GUEST_SYNC_ITEMS ceiling for zero-payload ordered actions and flip markers. Keep the byte budget as the RAM safety valve.
* fix(gta): stub Voice ports and implement sceKernelCheckReachability
Resolve North Yankton-path Voice Create/Delete/Connect/Disconnect/End NIDs and EnumerationThread reachability checks so leftover unresolved imports are not on the critical path.
* diag(gta): arm flip/present/wait probes after North Audio
Rate-limited load_progress TRACE for flip submit, ordered flip enqueue, present taken/not-taken, and GPU wait backlog so North Yankton freezes can be classified without full AGC tracing.
* fix(ampr): restore sequential offset=-1 reads for streamer packs
Re-wire PakDirectoryTracker into sceAmprAprCommandBufferReadFile (dropped in #216) so RAGE sequential pack reads no longer fail while the North Yankton UI keeps flipping. Also rate-limit CheckReachability miss paths for EnumerationThread diagnosis.
* fix(hle/videoout): Windows GuestImage opt-in and keep GTA intro without sync
Default the tracker off on Windows to avoid VirtualProtect thrash, gate AGC
texel-copy skips on Enabled so guest Bink planes keep shipping pixels, and
drain CPU-written images on the present thread when sync is opted in.
* fix(videoout): probe guest content when tracker off so UI can skip copies
Restores upload-known/texture-cache skips for Dead Cells menus, and uses a
sparse guest-memory fingerprint when GuestImageWriteTracker is disabled so
CPU-updated Bink planes still force texel copies for GTA intro.
* fix(audio): keep 128KiB host queue AudioOut2-only
Restore the default 32 KiB (~171 ms) PCM bed for classic AudioOut so
titles like Dreaming Sarah stay in sync; only AudioOut2 opens the deeper
queue needed for bursty FMOD Push on GTA.

* feat(gpu): GPU compute detile for guest tiled textures (Vulkan + Metal)
Move RDNA2 exact-XOR deswizzle (swizzle modes 5/9/24/27, 4bpp) off the CPU
onto a GPU compute pass. GnmTiling.GetDetileParams resolves the shared
addressing into DetileParams; the CPU fallback and both GPU kernels consume
the same params so they never disagree.
Vulkan (verified bit-exact on NVIDIA): SpirvFixedShaders.CreateDetileCompute
hand-emits the SPIR-V kernel; VulkanDetilePass.RecordDetile records the
dispatch into the async batch command buffer (never a blocking submit on the
render thread) with transients retired via fence; VulkanDetileSelfTest
(SHARPEMU_DETILE_SELFTEST=1) checks both entry points against the CPU detile.
Metal (Mac-untested): detile_compute.msl (detile_cs) + MetalDetilePass mirror
the Vulkan pass. The active Metal path CPU-detiles via the new
GnmTiling.DetileWithParams when a texture arrives packaged (empty RgbaPixels +
TiledSource/Detile), keeping Metal correct under default-on with no regression;
wiring MetalDetilePass live is the remaining on-device step.
Flags: GPU detile is default-on (SHARPEMU_GPU_DETILE=0 disables);
[GPU-DETILE] diagnostics gated behind SHARPEMU_LOG_GPU_DETILE=1.
Tests: 17 detile unit tests pass, incl. DetileWithParams and GetDetileParams
each matching TryDetile bit-for-bit across all supported modes/bpp, plus a
SPIR-V structural-validity test.

Vulkan (verified bit-exact on NVIDIA): SpirvFixedShaders.CreateDetileCompute
hand-emits the kernel; VulkanDetilePass.RecordDetile records into the async
batch command buffer (never a blocking submit on the render thread) with

VulkanDetileSelfTest (SHARPEMU_DETILE_SELFTEST=1) checks both entry points.
Metal (Mac-untested): detile_compute.msl + MetalDetilePass mirror the Vulkan

stays correct under default-on. Wiring MetalDetilePass live is a follow-up.
Flags: default-on (SHARPEMU_GPU_DETILE=0 disables); diagnostics behind
SHARPEMU_LOG_GPU_DETILE=1. Adds 17 passing detile unit tests.
* Fix: added support layered texture support for the GPU-Detiling.
