The POSIX alias takes (attr, int), returns EINVAL (22) for a null or
uninitialized attribute like the other pthread_attr setters, and
stores the value through scePthreadAttrSetsolosched, returning its
result in errno form. The signature and the stored int follow the SCE
twin in KytyPS5 and sharpemu; PS5PCEM implements the alias the same
way. The value is not applied to scheduling, recorded in TechnicalDebt.
Returnal (PPSA01285 v03.000.005) stops on it after eager binding

LEGO Horizon Adventures (PPSA14632, #734) and Palworld (PPSA23126,

Use the upstream CMASK implementation and remove the import requirement from image clears. Propagate storage-image creation failures. Test repeated clears, copied write-back, and failure without changing guest data.
AI-assisted: yes.
A wait on an equeue that holds socket events now blocks in poll/WSAPoll on
those sockets plus a per-thread loopback wake socket, instead of rechecking
every millisecond. Adding, triggering or deleting an event and closing the
equeue wake the blocked waiters. Closing a socket removes its read and write
events, as on FreeBSD. A read event also reports EV_EOF once the peer has
shut down its sending side.
sceKernelAddReadEvent/DeleteReadEvent and sceKernelAddWriteEvent/
DeleteWriteEvent register EVFILT_READ and EVFILT_WRITE events on guest
sockets. The equeue polls the host socket for readiness on each wait
and reports the readable byte count or the send buffer size in data,
with EV_EOF on hang-up or error.
pthread_cond_wait and pthread_cond_timedwait, and their sce counterparts, threw a
host exception when the mutex was unlocked, locked by another thread, or not yet
initialized, and dereferenced the adaptive static initializer. FreeBSD returns
EPERM for these (EINVAL for a destroyed mutex) before touching the condition.

The elected lane's inner spin loop never ended on Mesa ANV with the LDS in
a storage buffer. It now tries once and the outer loop elects again; the
update is unchanged.

Key 0x10 (GFX9_DCC_CLEAR_SINGLE in Mesa) marks a 256-byte block whose texels all equal its first texel. A CB DCC decompress pass over uniform comp-to-single keys now writes that texel over its block and stores uncompressed keys; a fast-clear eliminate over them throws.
When another readable allocation starts right after the buffer's allocation,
the bound range still ends at the first allocation: the bytes past it are
outside the buffer the descriptor's records describe, and binding into the
neighbour would send the range back to a copy on every draw.

RADV rounds a strided buffer descriptor's record count up, so stride * records
can run up to one stride past the end of the buffer's allocation. The guest
buffer region then no longer fits inside the allocation's host import and is
copied on the CPU, whole, for every draw that binds it.
When a strided descriptor ends less than one stride past the end of the
readable registered allocation that contains its base, the range is bound up
to the allocation's end. RetroArch's Dolphin core binds a 48 MiB stream buffer
with stride 20 (records 0x266667, 12 bytes past the allocation) on every draw.
With this change the buffer is bound in place from its import.

Background registration preparations (#2583) copy the device's
SpirvTarget, whose capability and extension spans point into the
device's shader profile. Driver::stop reset the device without waiting
for the detached pool, so a preparation still queued or running read
freed extension names and agc_driver crashed at exit on RADV.
Driver::stop now closes the pool after joining the queue workers: it
stops queueing and waits until no task is queued or running. A
preparation submitted after that runs on the caller's thread, which
holds its own reference to the device, like the existing fallback for
a pool without threads.
