v_min_f16, v_max_f16, v_min3_f16, v_max3_f16, v_med3_f16, v_pk_min_f16
and v_pk_max_f16 converted their sources to f32, ran the f32 min, max
or med3 with its NaN and signed-zero rules, and converted the result
back to f16 before applying the f16 NaN rules on the bits. The result
is always one of the sources, or for two zeros their sign bits
combined, so it is now chosen on the f16 bits: an integer comparison of
the bits with the sign folded into an ordering key, the same AND/OR
rule for two zeros, then the existing NaN, IEEE_MODE, denormal flush
and clamp rules.
The integer comparison doesn't depend on how the driver converts f16
denormals to f32. Comparing the f32 conversions instead fails on an
Intel UHD, whose UnpackHalf2x16 makes f16 denormals zero when the
module declares no f16 DenormPreserve, as these instructions no longer
convert to f16.
New test agc_driver_float16_min_max_bits checks the seven instructions
(VOP2 and VOP3 forms with abs, neg, op_sel and clamp; packed op_sel,
op_sel_hi and neg) on random and special inputs against a model of
those rules, in seven float modes including the f16 input denormal
flush. Current main gives the same results as the model on an RTX
4060, an Intel UHD and lavapipe.
Capture errno before the ENOTDIR lookup, translate EINVAL from a name
under a regular file to ENOTDIR, check the parent only once and strip a
trailing separator before taking it, and split the dense rmdir return.
On Windows mkdir_nid_postfix returned ENOENT and sceKernelMkdir and
sceKernelRmdir returned ENOENT or EIO when a regular file was used as a
directory in the path. FreeBSD mkdir(2) and rmdir(2) return ENOTDIR for
a path component that is not a directory.
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 an optional input helper for test runs without desktop input injection. Preserve physical input and release injected buttons automatically.
Validation: guest_pad tests and Python helper CLI smoke checks passed. Written with AI assistance.
signal() returned SIG_ERR with EINVAL for any signal without a host
equivalent, such as SIGHUP, SIGPIPE and SIGUSR1, while sigaction()
accepted them. FreeBSD's signal() is sigaction() with SA_RESTART and fails
only for numbers outside 1..128 and for SIGKILL and SIGSTOP.
The Windows formatter passed %p to the host CRT, which prints 16
zero-padded digits without a prefix. FreeBSD prints 0x followed by the
lowercase hex digits (0x0 for a null pointer), as if by %#lx.
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.

Replace per-draw Vulkan descriptor copies with a single write from retained buffer and image metadata. Keep per-draw guest snapshots, sets and resource ownership unchanged. Baseline RX 6600 profiling attributed 28% of graphics-worker cycles to descriptor copies.
Validation: mixed descriptor and snapshot regression passes on RADV RX 6600 and llvmpipe with Vulkan validation; graphics and guest-memory tests pass. Written with AI assistance.
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.

Report the thread's affinity mask as a 32-byte FreeBSD cpuset_t, with
FreeBSD 11's errors: ERANGE for any other set size, ESRCH for a null
thread and EFAULT for a null set.
EVO-PLAYER (PPSA99039 v0.11.0) imports it (Jb2uGFMr688) and calls it
once with a 32-byte set on pthread_self().
