get_cycles passes the pthread handle to pthread_getcpuclockid, which glibc
answers with an error for a thread that has already exited -- the else branch
below returns the last known value for exactly that case. bionic instead looks
the handle up in its list of live threads and aborts the process when it is not
there.
m_thread is never cleared when a thread ends and the performance overlay samples
every PPU, SPU and RSX thread on a timer, so one finished thread is enough to
take the emulator down with it. Latent here rather than absent: it needs the
overlay on and a thread to have gone.
Record the kernel tid at initialize and build the per-thread clock id from it
the way bionic does once its own lookup succeeds, so clock_gettime simply fails
for a dead thread, which is what the surrounding code already expects. Cleared
at finalize so a thread stops being sampled before it goes away. Other platforms
keep the original path.
Found and fixed by Zulux91 in PS3Native.
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.
- Some SPU programs inexplicably fail to compile when TBL2/TBX2 are used.
- As an insane workaround, first try to compile with TBL2/TBX2, if LLVM crashes while compiling, try to compile the same program without TBL2/TBX2.
