feat(libkernel): implement the pthread_rwlock try and timed lock functions
2026-10-05 11:42:29 +13:00
DotDebian f9625f2581 feat(libkernel): implement the pthread_rwlock try and timed lock functions
The POSIX layer only exported init, destroy, rdlock, wrlock and unlock.
pthread_rwlock_tryrdlock, pthread_rwlock_trywrlock,
pthread_rwlock_timedrdlock and pthread_rwlock_timedwrlock now wrap the
existing scePthreadRwlock functions and accept the static initializer.

The timed variants take an absolute CLOCK_REALTIME deadline. Like
FreeBSD libthr they try the lock first and only validate abstime when
the lock is not free. A null abstime throws, as pthread_mutex_timedlock
does.

scePthreadRwlockTryrdlock and scePthreadRwlockTrywrlock return EBUSY
when the caller already holds the write lock instead of calling into
std::shared_timed_mutex, where that is undefined behaviour.

Pacuka 98f050f879 fix(libkernel): default mutexes to error checking and add the adaptive type
The PS5 libthr (FreeBSD) creates error-checking mutexes by default and has
PTHREAD_MUTEX_ADAPTIVE_NP (type 4); relocking an error-checking or adaptive
mutex returns EDEADLK. Default mutexes were Normal and type 4 was mapped to
Normal, so a relock threw instead of returning EDEADLK, which aborted an
Unreal Engine title's recursive directory scan.

asimplestray 064006b617 feat(kernel): implement pthread semaphore lifecycle 2026-09-29 22:13:07 +00:00
Claude 210987745c
Merge upstream main into fix/audit-2026-09
Resolve conflicts with boykopovar/AnyPS5#10 (sce module loading) and
later upstream changes.

- Pthread Cond/Mutex: take upstream. It already releases mutex
  ownership across condition waits, returns ETIMEDOUT 0x8002003C, and
  rejects unlocks from non-owners for every mutex type.
- Pthread Thread: keep upstream's lifecycle, Windows adoption and job
  affinity; re-apply the POSIX fixes on top: reference-counted
  release on join/detach/exit, self-join rejection on both platforms,
  and scePthreadSelf adoption for threads not created by
  scePthreadCreate.
- Semaphore: keep upstream's TimedWait::Condition and wait tracing;
  re-apply sceKernelDeleteSema waking waiters with EACCES.
- Relinker: keep --windows-gui alongside upstream's --skip-sce-module,
  trampoline-aware Patch signature and new Python tests.

devilismyfriend a503d0b617 Merge remote-tracking branch 'origin/main' into feat/demons-souls-boot
Brings in main up to 9958d26 (homebrew runtime, POSIX wrappers in
libkernel, sce_module guest modules and --skip-sce-module, the --to-intel
general pipeline, libSceRandom, libSceRtc, libScePosixForWebKit,
libRenoirCore, test wiring).

Resolutions where both sides implemented the same thing:
- libkernel pthread: main's structure (lazy static initialisation,
  destroyed markers, MutexOperations/CondOperations, mutex protocol and
  condattr clock) with this branch's TimedWait deadlines and condition
  (precise timed lock/wait on Windows), wait tracing, the adaptive mutex
  type 4, POSIX default ERRORCHECK mutexes, EDEADLK/EPERM results instead
  of throws, and condition clocks honoured for absolute timeouts.
- libc locale: the guest Dinkumware ABI (_Locimp, facet vtables, short
  ctype/case tables, locale ids, stream storage) is kept because guest code
  inlines those layouts; main's C character functions are kept on top.
- libc stdio/strings/math: main's stream functions (guest FILE status
  sync), strerror/perror, remove, formatting, string and math exports win
  over this branch's duplicates.
- libc paths: main's working directory with this branch's path aliases
  resolved on the normalised guest path.
- libkernel file: this branch's sceKernel* results as SCE errors, main's
  POSIX wrappers and both fstat helpers.
- relinker: this branch's stub lowering keeps its trampolines through the
  main executable path; guest modules refuse lowerings that need stubs.
- AGC driver: main's rendering wait is executed by this branch's workers.

QDarkRex 76b7f998f5 fix(kernel): give every thread a pthread handle and keep mutex ownership consistent
- scePthreadSelf returned null on Linux and for threads not created by
  scePthreadCreate (including the main thread); such threads now get a
  lazily adopted, non-joinable handle
- scePthreadExit on Linux skipped FinishThread, losing the join value
- detached threads on Linux were never freed; use the reference count
  already used on Windows
- unlocking a recursive mutex from a non-owner was undefined behaviour;
  return SCE_KERNEL_ERROR_EPERM
- scePthreadCondTimedwait did not restore the mutex owner after waking,
  so another thread locking during the wait made the waiter's unlock
  fail with EPERM and left the mutex locked forever
- SCE_KERNEL_ERROR_ETIMEDOUT in Cond.cpp was 0x80020062 instead of 0x8002003C

devilismyfriend af3c2024ed feat(runtime): timed waits, sync primitive fixes, heap and RTC fixes, unattended-run switches
libkernel: a TimedWait service for condition variables, semaphores, event flags, rwlocks and
equeues with the scheduler tick; mutex/cond/sem corner cases the title hits; job worker
affinity is opt-in (APS5_JOB_AFFINITY). libc: calloc/realloc heap slot swap, a default
terminate handler with a backtrace, CPU topology helper. libSceRtc export fixes with tests.
libSceVideoOut: APS5_NO_PAD_INPUT ignores host input for unattended measurements,
APS5_FLIP_QUEUE_WAIT keeps a stalled process alive for a debugger. ApplicationHeap and
GuestRtc tests wired into the test build.

devilismyfriend f3ac61000d feat(runtime): guest arena, kernel thread/sync/file APIs, crash hooks
- libc: reserve guest memory in one arena below the PS5 map limit with
  MEM_WRITE_WATCH (GuestArena) and a caching guest heap; the allocation
  registry gains a generation counter, an invalidator callback for the
  driver's page cache and a pin waiter for leased ranges. This replaces
  the fault-based GuestMemoryTracking/GuestMemoryBacking layer, whose
  files are removed.
- libkernel: mmap/mprotect/munmap on the arena, flexible memory budget,
  real sceKernelVirtualQuery; POSIX pthread layer, rwlocks, timed locks,
  TSD, event flags; 0.5 ms scheduler tick and high-resolution sleeps;
  TSC/clock/time functions; file APIs return SCE errno codes; the APR
  file-streaming API.
- libc: vectored crash reporter with backtraces for fatal exceptions,
  SIGABRT, UCRT invalid parameters and process exit; SSE4a EXTRQ/INSERTQ
  emulation for Intel hosts; %ls/%lc/%S/%C with the guest's 16-bit
  wchar_t; hand-written setjmp/longjmp for the guest jmp_buf; a path
  alias table for short save-data mount points; more string, stdio and
  math exports.
