Titles that import it now load; calling it throws like the other
coredump queries, since host crashes are not turned into guest dumps.

DecodeShaderStages accepts LS, HS and an NGG passthrough ES, reads the
3-bit VGT_TF_PARAM fields, refuses its other bits but DISTRIBUTION_MODE,
and needs HOS levels that keep [1, 63]; 0x286-0x287 join the draw key.
Local and domain programs are prepared with their stage group: its
headers are merged over one set of defaults, and a local program left
unbound by the hull header is prepared at its first draw.
The local program ends at its jump into the hull half.
TessellationLowering lowers LDS and ring addresses that are affine in
the control point and relative index to tessellation interfaces with
strides from the code, and refuses accesses outside the patch, per-patch
writes from other control points and a modified primitive export. Hull
lanes read their own saved exec bit, also of host-subgroup-masked
copies; other masks are refused, gl_InvocationID loads as a scalar and
factors clamp to 63.
Use unlocked POSIX EOF/error queries after unlocked byte operations so status synchronization cannot reacquire the stream lock. Keep the verified UCRT status calls on Windows, and cover byte, status, error, and held-lock behavior.

agc_driver_dcc_keys_first_write only exercises the import window when the
device's own host import resolves the write protection of the imported
pages, as the NVIDIA driver does on Linux. CI's devices do not, so the
comparison that #2984 adds for BlockMaybeWritten units is not run there.
RunImportWindow opens an import window itself over a pending storage
image with GuestMemory::ImportWatched and stores the byte already there,
which leaves the same stamp without depending on the driver: the image
must stay pending and unchanged. A store of a new byte inside a window
must still be seen. Devices whose imports are compared print that the
window is not tested, as the recorder's (w) test does. Linux only: the
Windows path compares imports.
TechnicalDebt records that an identical-byte CPU store inside a window
cannot be told apart from the import, and that images tracked by layer
still upload again.

Titles that ship their own libc.prx or Unity's PS5Util.prx import
_umtx_op (04AjkP0jO9U) for atomic waits, call_once and futex-style
waits. Implement UMTX_OP_WAIT, UMTX_OP_WAKE, UMTX_OP_WAIT_UINT,
UMTX_OP_WAIT_UINT_PRIVATE and UMTX_OP_WAKE_PRIVATE as FreeBSD 11's
kern_umtx.c does, on the sceKernelSyncOnAddressWait waiter queue.

Two defects found in review of the Linux delivery:
A raise right after scePthreadCreate reached the new thread before
RunThread set currentThread, so scePthreadSelf() in the handler adopted
a second handle, and could deadlock on glibc's thread lock when the
signal interrupted pthread_getattr_np. The creator now blocks all
signals around the std::thread construction, so the child starts with
them blocked, and RunThread restores the creator's mask once the thread
is registered, as libthr does. A raise in that window stays pending and
is delivered just before the entry runs.
A handler that set reserved MXCSR bits made rt_sigreturn fail with
SIGSEGV. The MXCSR the handler leaves is now masked with the frame's
MXCSR_MASK (0xffbf when it reads 0), as FreeBSD's fpusetregs does, on
both platforms; Windows also keeps CONTEXT.MxCsr equal to
FltSave.MxCsr.
guest_raise_exception raises right after each of 50 thread creations and
checks scePthreadSelf() in the handler, and its context round trip sets
a reserved MXCSR bit and FZ and checks that only FZ is kept.
AI-assisted: yes

sceKernelRaiseException threw on Linux, so a title whose garbage
collector stops threads with it (Unity's PS5Util raises SIGUSR1 on each
thread and reads mc_rsp from the handler's context) could not run there.
The raise now sends the host SIGUSR1 to the target thread with
pthread_kill. The host handler, installed on first use with SA_SIGINFO
and SA_RESTART, builds the FreeBSD-layout ucontext from the interrupted
registers and the FXSAVE area, calls the guest handler on the target's
own stack and writes the registers back, so the handler's changes reach
the interrupted code, as they do on Windows. errno is left as the
handler leaves it, as libthr does.
A raise on another thread takes the target's join lock with the host
signal blocked and returns ESRCH once the thread has finished, so a
detached thread's pthread_t is never signalled after it exits. The
pthread_t is recorded when the thread is created or adopted. Handlers
are now lock-free atomics, as the host handler reads them.
guest_raise_exception now runs on every platform. It also checks that
r13 and xmm8 reach the handler and that r12 and xmm8 written by the
handler reach the interrupted code.

Forwards _sceUltWaitingQueueResourcePoolCreate and _sceUltSemaphoreCreate to the existing calls, like the other underscore Ult exports. Declares sceNetShowIfconfig, sceNpWebApi2GetMemoryPoolStats, Json::Value::setNullAccessCallBack, kqueue, kevent and one pad call of unknown name without an implementation.

Map red and blue exports, write masks and constant-color blend factors together. Reject conflicting simultaneous target constants.
Semantics: Mesa 26.2.2 src/amd/common/ac_formats.c ac_translate_colorswap; console equivalence remains unverified. Graphics tests passed. Written with AI assistance.
Allocate cached sets without individual-free pools. Reset a pool after its
last owner releases it. Keep stable pool indices, skip full pools, and
terminate if reset fails. No GPU wait is added.
This avoids RADV 26.2.2's affected individual-free allocation path.
Validation: Fedora 44 Release graphics tests pass. The reset-failure
regression fails on the previous behavior and passes on this change.
llvmpipe and RX 6600 pass the 3,301-set lifecycle test with core and
synchronization validation. Windows was not tested.
AI-assisted: yes.
FreeBSD's kernel_sigaction rejects SIGKILL and SIGSTOP only for a handler other than SIG_DFL, so signal(9, SIG_DFL) and signal(17, SIG_DFL) succeed. Drop the SIG_ERR rejection, which has no kernel basis and which sigaction does not apply.
Add standard quiet NaN generators nanf (DZU+K1wozGI) and nan (zck+6bVj5pA) to libc.
Resolves startup failure in VLC for PS5 (PPSA85300) where execution halts at nanf on Linux once strsep is available.
PPSA21703's Unity PSN plugin imports sceNpWebApi2GetMemoryPoolStats
(Xweb+naPZ8Y), so the title did not start.
sceNpWebApi2Initialize now records the pool size of each context and
sceNpWebApi2Terminate forgets it. The statistics report that size with
no peak or current use, as sceHttp2GetMemoryPoolStats does, since nothing
is allocated from the pool. A null output or an unknown context throws.
The signature and layout follow the Http2 statistics and are recorded in
TechnicalDebt.
The library gets its own CMakeLists.txt, equivalent to the generic rule,
to register its test.

The typed descriptor heaps write a null descriptor for a null guest
image, and the device therefore required VK_EXT_robustness2's
nullDescriptor. MoltenVK has the extension but not the feature, so on
macOS no Vulkan device opened and every GPU test was skipped. The
feature is now enabled when the device has it. Without it, the device
creates a placeholder image per typed image heap: 1x1, cleared to zero,
of the heap's dimension, sample count, numeric class and access, and a
null guest image binds the placeholder of its heap. A heap whose
placeholder the device cannot create throws when a null image reaches
it. TechnicalDebt.md lists where a placeholder differs from a null
descriptor.
agc_placeholder_images checks every image resource the recompiler maps
to a heap against that heap's placeholder, so the two cannot drift
apart, and agc_shader_device_profile now expects a device without
nullDescriptor to be accepted.

The entry said the result is flushed before or after the scale. The
lowering flushes the exact scaled value below the minimum normal before
rounding. Measured on RDNA2 (gfx1036) with round to nearest over every
half magnitude 0x0000..0x0fff of both signs, scaled by 2^-1 and 2^0,
IEEE 0 and 1, denorm16 0..3: no mismatch.

v_ldexp_f16 ignored the FLOAT_MODE denorm16 flush bits on main. Flush a
denormal half input when bit 0 is clear. When bit 1 is clear, flush the
result when its exact value is below the minimum normal half, decided
on the f32 product before the half conversion rounds it: 0x07ff scaled
by 2^-1 is zero on RDNA2, not the minimum normal. NaN handling and
destination high-half preservation stay the same.
