Fills NID gaps hit by PS5 titles during boot, controller setup, and
rendering, and surfaces the common runtime switches in the GUI. All
exports are additive (no behavior change to existing exports) and free of
NID and export-name collisions with upstream.
New export libraries:
- libSceBluetoothHid: Init/RegisterDevice/RegisterCallback success stubs so
titles proceed past Bluetooth controller setup (opt-out via
SHARPEMU_BTHID_UNAVAILABLE=1).
- libSceNpCppWebApi: Common::initialize no-op success; UE5 online titles
abort PS5-component startup on a negative SCE error.
Additions to existing libraries:
- libScePad: scePadOpenExt (shared PadOpenCore, accepts special ports 1/2 and
the ScePadOpenExtParam pointer), scePadClose, scePadGetExtControllerInformation.
- libSceVideoOut: sceVideoOutConfigureOutput, sceVideoOutInitializeOutputOptions.
- libSceAgc: DCB builders sceAgcDcbSetIndexCount, sceAgcDcbJump, DcbSetPredication,
SetPacketPredication (emit valid skippable packets; full draw processing TODO).
- libSceAmpr: measure and write KernelEventQueueOnCompletion pair.
- libKernel: scePthreadGet/Setschedparam, sceKernelChmod (validate and accept;
POSIX permission bits have no host equivalent on Windows).
- libSceNetCtl: sceNetCtlRegisterCallbackV6 (delegates to the v4 callback).
- libSceMouse: sceMouseInit.
- libSceUserService: sceUserServiceGetAgeLevel (adult, skips parental gates).
GUI: new Options Environment tab exposing common SHARPEMU_* switches as
toggles (BTHID_UNAVAILABLE, DISABLE_IMPORT_LOOP_GUARD, VK_VALIDATION,
DUMP_SPIRV, LOG_DIRECT_MEMORY, LOG_NP). Persisted in gui-settings.json and
applied to the emulator process environment at launch; localized with
English fallback.
* [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.
