The log flusher, audio worker, permission repair, sampler and core-thread factory were created with no attributes, which is 64 KiB of stack on this console; they ask for 256 KiB (src/title_threads.hpp). The release candidate ran every core through boot, menu and a Quick Menu action, four with threaded video, and PPSSPP for ten minutes with 25 menu cycles: no crash.

* PS5 RetroArch - the stack the title's own threads run on.
|
|
*
|
|
* A thread created with no attributes gets 64 KiB on this console (the
|
|
* payload SDK fork's thread probe, platform/docs/PROBE.md), a sixteenth of a
|
|
* desktop's. The title's own threads -- the log flusher, the audio worker, the
|
|
* permission repair, the sampler and the core-thread factory -- run little of
|
|
* their own code, but libc and the system libraries they call run on the same
|
|
* stack, and RetroArch's video thread faulted in a 66 KB frame on that
|
|
* default. So each asks for its stack. RetroArch's threads get 2 MiB (patch
|
|
* 0096), and the cores' 2 MiB (core_threads_ps5.cpp).
