* feat(gpu): GPU compute detile for guest tiled textures (Vulkan + Metal)
Move RDNA2 exact-XOR deswizzle (swizzle modes 5/9/24/27, 4bpp) off the CPU
onto a GPU compute pass. GnmTiling.GetDetileParams resolves the shared
addressing into DetileParams; the CPU fallback and both GPU kernels consume
the same params so they never disagree.
Vulkan (verified bit-exact on NVIDIA): SpirvFixedShaders.CreateDetileCompute
hand-emits the SPIR-V kernel; VulkanDetilePass.RecordDetile records the
dispatch into the async batch command buffer (never a blocking submit on the
render thread) with transients retired via fence; VulkanDetileSelfTest
(SHARPEMU_DETILE_SELFTEST=1) checks both entry points against the CPU detile.
Metal (Mac-untested): detile_compute.msl (detile_cs) + MetalDetilePass mirror
the Vulkan pass. The active Metal path CPU-detiles via the new
GnmTiling.DetileWithParams when a texture arrives packaged (empty RgbaPixels +
TiledSource/Detile), keeping Metal correct under default-on with no regression;
wiring MetalDetilePass live is the remaining on-device step.
Flags: GPU detile is default-on (SHARPEMU_GPU_DETILE=0 disables);
[GPU-DETILE] diagnostics gated behind SHARPEMU_LOG_GPU_DETILE=1.
Tests: 17 detile unit tests pass, incl. DetileWithParams and GetDetileParams
each matching TryDetile bit-for-bit across all supported modes/bpp, plus a
SPIR-V structural-validity test.

Metal (Mac-untested): detile_compute.msl + MetalDetilePass mirror the Vulkan
pass; the active Metal path CPU-detiles via GnmTiling.DetileWithParams so it
stays correct under default-on. Wiring MetalDetilePass live is a follow-up.
Flags: default-on (SHARPEMU_GPU_DETILE=0 disables); diagnostics behind
SHARPEMU_LOG_GPU_DETILE=1. Adds 17 passing detile unit tests.
* Fix: added support layered texture support for the GPU-Detiling.
* Fix: Added support for BlockTable (1 / 4 / 8 (Morton/Z-order))
* feat: added support for 8 and 16 bpp (bytes per element)
* Fixed a build failure specific to this branch

* [Kernel] Implement clock_getres and the POSIX pthread_once alias
clock_getres (smIj7eqzZE8) was missing entirely. It reports 100ns, which
is the resolution clock_gettime here actually delivers via
DateTimeOffset.UtcNow, rather than claiming the 1ns a caller might
otherwise rely on. A null res pointer is accepted per POSIX.
pthread_once (Z4QosVuAsA0) needed no new logic: libKernel exports the
same routine under two NIDs and only scePthreadOnce (14bOACANTBo) was
registered. Shipped middleware links the plain name.
Both are imported by DOOM + DOOM II (PPSA21444): clock_getres blocked
party.prx from initialising, and pthread_once is used by libcohtml,
libPlayFabMultiplayer, party.prx and the eboot.

* [Libs] Implement sceAgcGetIsTrinityMode, NpReachability and Trophy2 info
Three exports DOOM + DOOM II (PPSA21444) imports and currently receives
unresolved-stub errors for.
sceAgcGetIsTrinityMode reports the base console this backend emulates. It
returns the flag in rax and writes no guest memory: the observed rdi at
the call site sits inside the AGC state block, immediately below the
shader handles the guest stores, so writing through it would corrupt live
state if that register is stale rather than an out-pointer.
sceNpRegisterNpReachabilityStateCallback accepts the callback and never
fires it, matching the existing sceNpRegisterStateCallback handling.
Reachability transitions only occur on a live PSN connection.
sceNpTrophy2GetTrophyInfo reports NOT_FOUND rather than success.
Succeeding requires filling SceNpTrophy2Details and SceNpTrophy2Data,
whose layouts are not confirmed here, and a title trusting zeroed details
would read an empty name and grade 0 as real data. NOT_FOUND is a
documented outcome callers already handle.

* [Kernel] Implement the POSIX libKernel exports titles link directly
libKernel exports many routines under both sce-prefixed and plain POSIX
NIDs, and shipped middleware links the latter. These nine are imported by
DOOM + DOOM II (PPSA21444) and had no registration at all.
Aliases onto existing implementations, identical argument order:
mprotect (YQOfxL4QfeU), munmap (UqDGjXA5yUM), setsockopt (fFxGkxF2bVo)
New:
getpagesize reports OrbisPageSize (16 KiB), not the host 4 KiB. An
allocator rounding to the host value produces sub-page offsets that
every mapping call here rejects for misalignment.
pthread_rwlock_tryrdlock/trywrlock get a dedicated non-blocking core.
They deliberately do not reuse TryAcquireBlockedRwlock, which
decrements WaitingWriters -- correct only for a thread that previously
incremented it. A fresh try never did, so reusing it would consume
another thread's waiter count and let a queued writer be skipped.
getsockopt reads back the three options this backend tracks (SO_NBIO,
SO_REUSEADDR, SO_ERROR) and rejects the rest rather than returning
success with an untouched buffer the caller would treat as real.
send maps WouldBlock onto the existing net error path.
inet_ntop converts AF_INET/AF_INET6 and returns the destination
pointer per POSIX, failing rather than truncating when it will not fit.

* [Kernel] Implement the POSIX mprotect, munmap and getpagesize aliases
mprotect and munmap forward to the existing sceKernelMprotect and
sceKernelMunmap; the argument order is identical, so they are plain
aliases rather than separate implementations.
getpagesize reports OrbisPageSize (16 KiB), the granularity this backend
maps and aligns against, not the host's 4 KiB. An allocator that rounded
to the host value would produce sub-page offsets that every mapping call
here then rejects for misalignment.

* [Kernel] Implement the POSIX _nanosleep symbol
libKernel exports nanosleep under two NIDs: yS8U2TGCe1A for the plain
name and NhpspxdjEKU for the underscore-prefixed _nanosleep that libc
conventionally provides alongside it. Only the former was registered.
Both are POSIX-side symbols, so this shares NanosleepCore with posix:
true - reporting failure as -1 plus errno rather than returning an
OrbisGen2Result the way sceKernelNanosleep does.
Not exercised at runtime: no title currently on this branch imports
_nanosleep, so the choice of error convention rests on it being the
same libc routine as nanosleep, not on observed behaviour.
* [Kernel] Implement the POSIX-named pthread aliases
libKernel exports each of these routines under two NIDs: a scePthread*
name and the plain POSIX name. Only the scePthread* half was registered,
so middleware compiled against POSIX headers linked an unresolved stub.
Adds the POSIX-named export for fourteen routines, each delegating to
the existing implementation:
pthread_setprio pthread_attr_setschedpolicy
pthread_getschedparam pthread_attr_setdetachstate
pthread_attr_getschedparam pthread_attr_setschedparam
pthread_attr_getstack pthread_attr_setinheritsched
pthread_attr_get_np pthread_attr_setguardsize
pthread_attr_getstacksize pthread_attr_getguardsize
pthread_attr_getdetachstate pthread_rename_np
Arguments are identical in both forms, and per the convention set by
scePthreadOnce's alias the POSIX name returns the same OrbisGen2Result
rather than translating to errno.
The equivalent POSIX names for mkdir, listen, accept and recv are
deliberately not included here. Those pair with sceKernelMkdir and the
libSceNet entry points, whose error convention differs from the POSIX
one, so they need a decision about error translation rather than a
straight delegation.
