The H+8UBOwfScI import was a throwing stub (libcCyberUnknown08). It is
the NID of "__powidf2", the double-precision integer-power helper that
complements __powisf2.
On a PS5 (firmware 13.60) pthread_setschedparam and
scePthreadSetschedparam accept only SCHED_FIFO and SCHED_RR with a
priority of 256 to 767 or 896 to 959, return EINVAL otherwise, and
keep the policy for pthread_getschedparam. A created thread takes the
policy of explicit scheduling attributes, or its creator's when it
inherits. Here any policy and priority were accepted and SCHED_FIFO
was always reported.

Wait for overlapping CPU writebacks and completion labels before importing buffers or accepting cached image resources. Cover texture data and compression metadata, retain asynchronous disjoint and GPU-only dependencies, and avoid recursive completion waits.
Reproduced fresh-buffer and cached-image failures with CPU Vulkan before fixing them. Regression covers fresh/reused bindings, dispatch/draw copied writers, texel/metadata updates, labels and no-wait cases; passes CPU Vulkan and RX 6600 synchronization validation. Graphics and guest-memory suites pass. The Skyrim loading GPU fault remains unattributed.
AI-assisted implementation and independent code review.
Main refuses every storage view of a depth or stencil plane that is not
2D. A 2D array view is now taken as the plane only at layer 0 with one
layer; a view with more layers or another base layer still throws.
A one-layer 2D array view replaces a 2D view of the plane like any other
view, so a store back through the replaced 2D view throws. The depth
storage dispatch test runs one-layer views of both planes and checks
that the depth and stencil tests see what they stored, and that a
two-layer view still throws.
A storage view of a depth or stencil plane was taken for the depth surface
only as a 2D image. A 2D array view of layer 0 with one layer and the
plane's extent and format is the same plane, and now gets the plane's
storage image too; a view with more layers still takes the ordinary path.
The plane's storage image is recreated when the view's dimension changes.
PPSA01289 (Sackboy: A Big Adventure) binds the stencil plane of its
2880x1620 D32S8 surface as a one-layer R8_UINT 2D array from a compute
shader during presentation, and read guest memory instead of the stencil.

Since #1463, every f16 operand read decodes sign, exponent and mantissa
with integer operations, 8 to 12 instructions more per read than
UnpackHalf2x16 on NVIDIA. The decode works around an AMD Windows driver
that folds the mask of a byte-selected half into UnpackHalf2x16.
A new target flag, float16DenormPreserve, is set when the device reports
shaderDenormPreserveFloat16 and denormBehaviorIndependence ALL, the same
rule as float64DenormPreserve. With it, EmitF16BitsToF32 uses
UnpackHalf2x16 and declares DenormPreserve for 16-bit floats, under
which SPV_KHR_float_controls keeps unpacked subnormal halves. NVIDIA
returns the default NaN for every NaN half, so the NaN bits are rebuilt
from the half: its sign at bit 31, its payload at bits 22:13. The
DenormPreserve 16 mode is declared once, shared with the native f32 to
f16 conversion. Without the flag (lavapipe; RADV reports 32_BIT_ONLY)
the integer decode stays. Halves of fields narrower than 16 bits, such
as SDWA byte selects, keep the integer decode on every device.
The flag is serialized (request version 17) and part of the cache key.
New test agc_driver_f16_to_f32_unpack converts all 65,536 halves, with
nonzero high bits, through v_cvt_f32_f16, and byte-selected halves
through v_add_f16 SDWA, with each decode the device supports, and
compares the bits with an exact decode. agc_driver_f16_to_f32_unpack_spirv
checks which decode the SPIR-V uses with and without the flag.
A fast clear of a packed float color target (format 36) was refused as unencodable. Give the format
a DCC layout (11, 11 and 10 bit float channels) and its one value, so 0000, 0001, 1110 and 1111
clear codes fill the texels and a texture keeps those keys.

strftime handed most conversions to the host's strftime, which differs
from FreeBSD 11's for E and O modifiers on conversions glibc does not
pair with them (%Ea was printed literally), padding flags on %+ and %v,
years outside 1000 to 9999 (%Y printed 899 and -1 where FreeBSD prints
0899 and -001), and out-of-range fields (%I of hour 100, %u of weekday
8). On Windows the padding flags printed nothing. strftime now follows
FreeBSD 11 strftime.c with the C locale on every host, and asctime
follows FreeBSD 11 asctime.c, padding years to four digits and setting
longer years apart.

sceKernelVirtualQuery, sceKernelMunmap, sceKernelReleaseDirectMemory and the
reservation paths walked a copy of the whole allocation registry or of every
direct mapping under one lock on each call. The registry now answers lookups
from its ordered map, applies range replacements as patches instead of
rebuilding the map, and direct mappings carry an index by physical offset so a
release finds only the mappings it covers. Minecraft (PPSA17221) holds about
7,000 direct mappings and spent its world generation in these walks.
