* fix(kernel): implement APR ResolveFilepathsWithPrefixToIdsAndFileSizes
Resource streamers resolve relative paths against a shared prefix; without
this HLE every call returned NOT_FOUND and assets never got real ids/sizes.
* fix(remoteplay): stub Initialize and GetConnectionStatus as disconnected
Titles probe Remote Play during pad/network bring-up; unresolved imports
returned NOT_FOUND. Report initialized + disconnected so callers take the
normal offline path.
* fix(agc): accept Gen5 hull shaders that omit PGM_LO/HI in CreateShader
Type-5 headers can start with RSRC1/RSRC2; rejecting them left null handles
and Main Thread AVs. Scan the SH table and skip PGM patch when absent.

* fix(kernel): reject getdents on file fds and emit . / .. for empty dirs
Returning rax=0 for non-directory or empty listings looked like EOF and
let GTA treat the fd as a pointer (fiWriteAsyncDataWorker AV at 0xB1).
* fix(hle): enable GuestImageWriteTracker CPU sync on Windows
Windows previously hard-disabled the tracker, so CPU-written guest
planes never marked dirty and host textures stayed empty. Arm pages
with VirtualProtect, handle write AVs in VEH, and warm/test on
VirtualAlloc memory so protect cannot poison the CRT heap.
* fix(agc): skip CB metadata draws for EliminateFastClear/Fmask/DCC
CB_COLOR_CONTROL modes 2/5/6 are colour-buffer metadata ops; applying
the bound shader as a normal colour draw corrupts subsequent composites.
Decode MODE from bits [6:4] and return before translate.
* fix(agc): merge Prospero attrib-table formats onto IR vertex inputs
IR-discovered BufferLoadFormat often keeps a stale float sharp format;
patch DataFormat/offset from the AGC attrib table (semantic index),
allow offen fetches, and map quirks 113/121 through NarrowVk for host
vertex input.
* fix(audio): harden AudioOut2 stack out-buffer writes against canary smash
Titles that stack-allocate AudioOut2 outs next to the frame canary were
corrupted by oversized or mistyped HLE writes; keep ContextPush pacing.
* Revert "fix(memory): reserve only large regions (#608)"
This reverts commit 8f9456229a.
* fix(gpu): decode Gen5 R16 and RG32 render-target formats
* fix(audio): AudioOut2 host beds, deeper waveOut queue, AJM MP3
GTA V Enhanced routes intro/menu audio through AudioOut2 and FMOD's AJM
MP3 path. Wire PortCreate/PortSetAttributes/ContextPush to dual host
stereo streams, deepen WinMM queue to 128KiB, and decode AJM codec 0
with a stateful NLayer helper so menu music is not silent.
* fix(agc): map PS interpolants via SPI_PS_INPUT_CNTL semantics
Identity ATTR→param wiring ignored hardware remapping, so UI draws
got wrong (or empty) interpolants. Pack CNTL from matched PS/GS
semantics, thread it into Vulkan/Metal as Location/Flat, and fingerprint
it in the graphics shader cache key.
* fix(agc): rect-list/NGG strips, Index8 expand, and GE_INDX_OFFSET
NGG single-rect UI needs triangle-strip expansion; Prospero Index8 must
expand to host u16; glyphs need base vertex from GE_INDX_OFFSET. Skip
param-less rect-lists instead of inventing colour draws.
* fix(np): report GTA Story Mode addcont entitlements as owned
NpEntitlementAccess was returning an empty add-on list, so GTA V Enhanced offered Buy Story Mode. Publish the installed license labels and stub premium-event registration so offline sessions take the owned path.
* fix(cpu): prefer native workers for all guest entry stubs
Route thread entry, continuation, and main entry through RunGuestEntryStub so guest stubs are not invoked above CLR-managed frames (UnmanagedCallersOnly FailFast). Keep requireNativeWorker for tbb_thead; other paths prefer workers with calli fallback.
* fix(agc): implement Rewind/Jump writers and IT_REWIND waits
GTA Subrender AVs came from AcbJumpGetSize / DcbRewind returning NOT_FOUND as packet sizes. Add IT_REWIND and INDIRECT_BUFFER writers, patch SetRewindState into the GPU wait registry, and nest-parse 4-dword jumps.
* fix(gpu): use AddrLib ExactXor for Gen5 Standard256B (mode 1)
Mode 5 already had Standard4K ExactXor; mode 1 still used the generic StandardSwizzle block table, which mis-detiles Gen5 UI atlases.
* Revert "fix(cpu): prefer native workers for all guest entry stubs"
This reverts commit 31c4db0d38.
* fix(memory): commit-first large maps; reserve only on failure
Replace the #608 always-reserve-only exact-map path with allocate-first and lazy reserve fallback when a huge non-exec commit cannot be satisfied. Prime and widen GetPointer commit so the fallback path is safer for native walkers. Drops the need for a hard #608 revert.
* [Agc] Implement fused shader half exports
* fix(agc): accept optional hull state in CreatePrimState
Port the CreatePrimState hull-optional path from #583 so fused HS pipelines (GTA) are not rejected with INVALID_ARGUMENT. Geometry-derived CX/UC writes are unchanged; hull is traced only.
* fix(videoout): restore thread-safe VulkanHostBufferPool (#564)
The 6db095e wipe dropped CasualcoderDev's lock-ordering-safe pool. Concurrent Return/TryTake without the gate races after the first present and can hang the submit path.
* Revert "fix(agc): implement Rewind/Jump writers and IT_REWIND waits"
This reverts commit bec77bf083.
* test(memory): align lazy-commit expectations with commit-first policy
Fake hosts must reject Allocate so reserve-only paths still run, and GetPointer asserts the 32 MiB prime range including AlignUp spill.
* 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.

* [Core] Add POSIX native execution and PS5 SELF support
Extend the native backend, guest TLS, fixed-address memory, and loader paths needed by PS5 titles on Windows, Linux, and macOS. Keep workstation GC so high-core-count hosts do not reserve over fixed guest image bases.
* [HLE] Expand PS5 service and media compatibility
Add the kernel, threading, save-data, networking, audio, video-codec, font, dialog, and service exports required by newer PS5 software. Preserve every SysAbi NID currently registered by main while adding the compatibility surface used by ASTRO BOT.
* [AGC/Vulkan] Extend Gen5 shader and presentation support
Expand PM4 handling, Gen5 shader translation, MRT and packed export support, guest image tracking, depth initialization, texture aliasing, and Vulkan presentation. Add the performance overlay and address-filtered diagnostics used to validate ASTRO BOT with original shaders.
* [Core] Align static TLS reservation across hosts
* [Pad] Align primary user ID with UserService
* [Gpu] Preserve runtime scalar buffers across renderer seam
* [AGC] Restore omitted command helper exports
* [Vulkan] Reuse primary views for promoted MRT targets
* [Vulkan] Preserve scratch storage bindings in compute dispatches
* [agc] WAIT_REG_MEM suspend/resume, draw packet fixes, new HLE exports, debug cleanup
Rebased onto upstream 79a7437 (par274/sharpemu, rewritten history).
- GpuWaitRegistry: DCBs suspended on unsatisfied WAIT_REG_MEM are re-polled
against guest memory on every submit; fixed 64-bit and standard packet parse
offsets, apply the mask, treat PM4 compare function 0 as "always".
- TryReadSubmittedDrawCount: accept the 5-dword ItDrawIndex2 form emitted by
DcbDrawIndex (count at +4); menu draws were silently discarded before.
- sceAgcDriverSubmitMultiDcbs: reversed ABI (rdi=address array, rsi=dword
sizes, rdx=count).
- VideoOut: vblank events, sceVideoOutGetFlipStatus, buffers registered via
sceVideoOutRegisterBuffers are valid flip targets.
- New HLE: libc stdio (fopen/fread/fseek/ftell/fclose/fgets), Dinkumware
_Getpctype ctype table, NpTrophy2 stubs, AMPR PAK sequential-read tracker,
MsgDialog lifecycle, NGS2 alt NIDs + dummy vtable for handle objects,
guarded memset intrinsic, abort()/strcasecmp null-arg recovery.
- Removed investigation-only code (INT3 breakpoints, qfont/mcpp dumps,
error-candidate printf traces, unconditional debug logs).
First rendered frame: Quake (PPSA01880) presents a 1920x1080 guest frame.
* Implemented a guarded native intrinsic (rep movsb) in DirectExecutionBackend to bypass HLE dispatch overhead, while preserving memory safety checks.
* [hle] clock_gettime clock ids, AudioOut2 canary fix, NID rebinds, new offline stubs
- clock_gettime (lLMT9vJAck0): support CLOCK_SECOND and the *_PRECISE/*_FAST
variants instead of returning EINVAL, which games treated as fatal and
retried in a tight loop.
- AudioOut2: context param writes shrunk to the guest-observed layout (the
old 0x80-byte reset smashed the stack canary at +0x60 and killed audio
init); ContextQueryMemory writes the single u64 the caller expects.
- NGS2: dropped wrong alt-NID aliases (they hash to sceImeUpdate,
sceMouseRead, sceSystemGestureUpdateAllTouchRecognizer - now bound in
their real libraries); added sceNgs2PanInit; fixed VoiceGetState NIDs.
- New verified stubs: sceUltInitialize, sceNpUniversalDataSystemDestroyHandle,
sceNpGetOnlineId, sceNpGetNpReachabilityState, sceImeKeyboardOpen,
sceImeKeyboardGetResourceId, sceMouseOpen, sceKernelAprGetFileSize.
- Import gateway: unwind guest workers at dispatch during backend teardown;
env-gated SHARPEMU_LOG_THREAD_MODE tracing.
* [cpu] Isolate guest execution on native worker threads
Guest entry stubs no longer run above CLR-managed frames: each run is handed
to a pooled raw OS thread whose loop is emitted native code. While guest code
executes there is not a single managed frame on the thread and it stays in
preemptive GC mode, so the GC never walks a frame chain interleaved with
guest stubs that carry no CLR unwind info (the ReversePInvokeBadTransition /
UnmanagedCallersOnly FailFast class of crashes on pumped guest threads).
- NativeGuestExecutor: CreateThread + emitted run loop (WaitForSingleObject,
UnmanagedCallersOnly prologue/epilogue, entry stub call, SetEvent). The
prologue rebinds guest TLS, the host-RSP slot, thread affinity and the
Active* ambient per run, so workers carry no guest identity and pool
freely; the orchestrating managed thread parks in a preemptive wait.
- All three entry sites route through RunGuestEntryStub: guest thread
entries, blocked-continuation resumes, and the main ExecuteEntry.
- Teardown stops workers before any executable stub or TLS index they
reference is freed; a worker that will not stop leaks its loop instead of
freeing running code.
- Kill switch: SHARPEMU_DISABLE_NATIVE_GUEST_WORKERS=1 restores the inline
calli path.
