Hangs where the RSX idles were only ever visible from the RSX side, so a stall
report now names every guest thread, its state, PC and function, and for SPUs adds
the reservation counters -- conditional store calls, failures, notifications, and
the SPURS heuristic's deliberate non-notifications -- plus where the host thread
last was in cpu_task. block_counter alone cannot separate a thread livelocked
retrying PUTLLC from one that is genuinely idle; both report zero blocks a second.
The SPU code window prints once per process. Unguarded it re-emitted a whole
function on every stall dump, measured at 538 lines a second over 31 dumps with a
690 MiB log left behind, which on Android is itself a stall -- it was degrading the
hang it was meant to describe, and it buried the state lines that answered the
question.
do_local_task counters cover the case the profiler cannot: it reports the thread is
in Local task and has been for 0.00s, which together mean it is not stuck there at
all and the FIFO loop is calling it repeatedly. Which FIFO state, and whether guest
GET equals PUT, separates a starved RSX from a stuck one.
tools/ps3autotests drives ps3autotests on a device over adb and diffs per
instruction against real-hardware output; compare-platforms.py does the three-way
ARM/x86/hardware split that separates shared upstream failures from ARM-only ones.
This is what found the CFLTS and FMS divergences.
Adds an Android build of the RPCS3 core plus a Compose UI, and fixes several
things that stopped it working on ARM64.
Renderer:
- Emit concrete bounds for runtime sized arrays in uniform blocks when
VK_EXT_shader_uniform_buffer_unsized_array is missing. Adreno does not have
the extension, so every game pipeline failed with VK_ERROR_UNKNOWN and only
overlays drew.
- Probe and request that extension properly instead of chaining its feature
struct unconditionally.
- Hand VMA the Vulkan function pointers it needs under VK_NO_PROTOTYPES.
- Rebuild the surface and swapchain when the window is lost instead of killing
the RSX thread.
- Only create a GLES context when the GL renderer is actually selected.
SPU:
- Sum instead of taking an absolute difference in the ARM64 block verification
checksum. The difference collides on the near identical job binaries an SPU
job manager streams through one local store address, so a cached block could
run against another job's code.
Threading:
- Implement thread affinity on Android using sched_setaffinity.
- Add an ARM big.LITTLE core arrangement so SPU and RSX threads land on the
fast cores.
Misc:
- Detect the host CPU for the LLVM JIT instead of pinning cortex-a34.
- Fall back to the default audio device when cubeb cannot enumerate.
