* Boot compatibility fixes for UE titles, GUI toggles, and DeS render/boot work
Checkpoint of the Monster Truck Championship and Demon's Souls boot work.
Each piece is independently useful and verified against the titles.
- playgo: scePlayGoGetLocus now returns BAD_CHUNK_ID for chunk ids outside
the known set, matching real firmware. Titles enumerate chunk ids until
that error; answering OK for every id made the scan wrap the ushort range
and spin forever. Missing-sidecar and no-app0 fallbacks report a
fully-installed single chunk 0 so scePlayGoOpen keeps succeeding.
- kernel: restore the SHARPEMU_WRITABLE_APP0 opt-in. Unpackaged UE dumps
write their Saved tree under /app0 during PS5 component init and treat
the denial as a fatal boot error.
- pad: accept handle 0 as the primary pad across all pad calls. Real
firmware hands out small non-negative handles and some titles read state
with handle 0.
- bthid: env-gated experiment hooks for the Thrustmaster wheel middleware
investigation (fail-only-RegisterCallback modes and a synthetic
enumeration callback with a zeroed event struct). All default off.
- gui: add SHARPEMU_LOG_IO and SHARPEMU_WRITABLE_APP0 toggles to the
Environment tab.
- videoout: per-swapchain-image render-finished semaphores (the shared
semaphore raced the swapchain); whole-mip-chain layout init for offscreen
guest images (sampled binds read mips stuck in Undefined); GPU-resident
texture availability now canonicalizes through the texture format table
and accepts compatibility-class aliases, cutting per-frame CPU texture
re-reads (143 GB -> 55 GB per 300 s in Demon's Souls, 0.2 -> 0.5 fps).
- hle: add sceSystemServiceGetNoticeScreenSkipFlag,
sceSystemServiceGetMainAppTitleId (title id published from the runtime),
and sceNpWebApi2CreateUserContext (refuses so the online layer backs off).
- rtc: SHARPEMU_RTC_PROBE_RANGE diagnostic dumps the code around a busy-wait
caller of sceRtcGetCurrentTick once; costs nothing when unset.
* [ShaderCompiler] Fix VReadlaneB32 scalar destination field
The scalar destination lives in the low vdst byte (bits 0-7); it was read
from bits 8-14, the VOP3B carry-out field readlane does not have, sending
every readlane result to s0. Verified against raw gfx10 encodings and
LLVM's assembler tests (v_readlane_b32 s5, v1, s2 -> low byte 0x05).
* [VideoOut] Survive device loss and flip-order asserts without dying
Two ways a frame could take down the whole presenter:
- Device loss between any two Vulkan calls in a frame unwound the window
thread, and the Dispose-time fence check then threw again, masking the
original error. Catch the loss at the frame boundary, retire
presentations and guest submissions whose fences can never signal, and
keep the window loop pumping so the game (audio, logic) carries on.
- The ordered-flip capture invariant is violated ~100 times per run by
Demon's Souls (PPSA01342); on debug builds the Debug.Assert fail-fasts
the process with nothing in the log. Downgrade it to a once-per-version
warning until the capture/wait ordering is understood.
* Fix Dead Cells shader cache regression
