updateGsCsrFieldForVSync runs on the detached vsync worker and updated the
FIELD bit with a non-atomic read-modify-write of GSRegisters::csr while
guest threads concurrently read/write the same word (MMIO read32/read64 and
the W1C handling in write32/write64) and the GIF path sets SIGNAL/FINISH.
Even though the writers touch disjoint bits, a whole-word RMW loses the
other side's update: a clobbered SIGNAL/FINISH set hangs a game
synchronizing on GS completion, a clobbered W1C clear re-asserts a handled
interrupt, and a clobbered FIELD toggle stalls interlace field polling.
ThreadSanitizer flags the race on main (updateGsCsrFieldForVSync vs
PS2Memory::write64 and GS::writeRegister).
Make the field std::atomic<uint64_t> and perform every update as a single
atomic RMW:
- vsync FIELD toggle -> fetch_or / fetch_and
- MMIO W1C writes -> compare_exchange loop in shared helpers (a
load-then-store pair would still race); a 32-bit store to the CSR's upper
dword previously bypassed the W1C special case entirely and went through
the plain merge branch - both halves now share the same atomic helper
with unchanged guest-visible semantics
- GIF SIGNAL/FINISH -> fetch_or
- reads -> load()
std::atomic<uint64_t> is lock-free on all supported targets (static_assert
added), the struct's size/alignment asserts are unchanged, GSRegisters is
never copied by value, and default (seq_cst) ordering is used throughout -
these operations are rare (vblank ticks, GIF signals, CSR MMIO), so
reviewability wins over micro-optimization.
New regression test: two racer threads each own one status bit (SIGNAL /
FINISH) and loop 80k GIF-set + W1C-clear cycles verifying their own bit
after each half-op while the vsync worker toggles FIELD. Fails 20/20 runs
against the previous code, passes 50/50 with the fix, ~350ms runtime, no
sanitizer needed.

* fix: semaphore syscalls return sid on success instead of KE_OK
The PS2 EE BIOS returns the semaphore ID on success for all semaphore
syscalls, not zero. PollSema, WaitSema, SignalSema, and DeleteSema were
all returning KE_OK (0) on success, which breaks games that compare the
return value against the semaphore ID.
DQ8's init code polls a mutex semaphore at 0x12A670 and checks the result
against the semaphore ID using bne. With KE_OK returned, the comparison
always fails and the game spins forever at PC 0x164978 and never starts.
Other games that follow the same EE BIOS convention would hit the same
problem. CreateSema already returned the ID correctly; this brings the
other four operations in line with the same convention.
The fix is five changes in Sync.cpp: the four return sites are updated to
return sid, and the count-decrement guard in WaitSema is changed from
ret == 0 to ret >= 0. The guard change is necessary because ret is now
seeded to sid (a positive value) on the success path, and the old equality
check would have silently stopped decrementing the semaphore count. Error
paths (KE_WAIT_DELETE, KE_RELEASE_WAIT) are negative and still correctly
bypass the decrement.
Tests are updated to expect sid instead of KE_OK on success paths, and new
test cases cover the blocked-wait-then-signal path (the actual DQ8 scenario),
force-release via ReleaseWaitThread, and the count-decrement guard directly.
* fix: update stale KE_OK assertions in expansion and SIF RPC tests
Two test files were not updated alongside the semaphore return-value change.
PollSema and SignalSema now return sid on success; update the four assertions
that expected KE_OK on those success paths.
* fix: tighten WaitSema count-decrement guard to ret == sid
ret is seeded to sid on success and only ever overwritten with negative
error codes, so ret == sid precisely expresses "this wait acquired this
semaphore" — more explicit than the looser ret >= 0.
