A depth surface lives only in its Vulkan image, so a view of its memory
with another layout could only throw, and a matching view kept reading
the image after other writes over its memory. Retire the surface when a
color target or a written storage image it does not serve overlaps its
planes, or when a view it cannot serve finds guest memory over the planes
written since the surface was last bound; lookups then skip it and the
view reads the memory like any texture. Binding the target again brings
the surface back.

The second queue that settles imports is always created on Windows, and a device without one keeps
the comparisons. The other-family settle path is tested through the recorder test device built
with its settle queue on another family (agc_import_watch_other_family) instead of
APS5_SETTLE_OTHER_FAMILY.
The settle read keeps a private import's window open for one round trip on the settle queue, so a
store from another thread can land inside it. CheckImportWindowOtherThread: a store of new bytes from
another thread within the window counts as written, and a same-value one keeps its possible CPU
touch. The debt entry notes the longer window.
On Windows a host import without a section alias left guest write tracking, and its changes were
found by comparison. Since resident direct memory became private MEM_WRITE_WATCH memory, its
imports take that path, and every storage-texture refresh over it compares its whole snapshot.
ProbeImportWriteProtection gets a Windows body on MEM_WRITE_WATCH scratch memory, and
decideImportWatch keeps direct imports of private read-write memory watched when GetWriteWatch
stays honest after an import's first GPU use. The driver marks every imported page written until
that use completes, so each such import is settled inside ImportWatched's window by a 4-byte read on
a second queue of the graphics family (the imports lock comes after GpuMutex, so the main queue
cannot be used there). APS5_NO_WATCHED_PRIVATE_IMPORTS=1 keeps the comparisons.
Decode the four PA_SC_AA_MASK fields at the rasterized sample count. Use the native Vulkan mask when all four pixels agree and apply varying masks in the fragment shader, preserving helpers and combining coverage with alpha-to-coverage and shader mask exports. Add the normalized masks to pipeline, draw and shader keys and the versioned replay request.
Refuse unsupported conservative-raster, centroid and early depth/stencil memory-write cases. Synthetic readbacks cover driver submission, depth/stencil suppression, fragment stores and one-sample and four-sample coverage.
Reject native sampled views of the depth image attached by the same draw before pipeline creation. Keep unrelated views, other devices and the single-sample path unaffected. Add unrun native-view refusal and scope controls; full dependency-stack build and runtime validation remain pending.
Adapt our preserved native-depth sampling work from c0d9edf and sample-aware footprint work from 6e35a877, retaining creation-time coherence and initial HTILE proof. The descriptor interface in upstream PR 4820 remains a separate prerequisite. This source draft has not been built or run.
A dump is fully installed, so scePlayGoGetSupportedOptionalChunk and
scePlayGoGetOptionalChunk report every optional chunk (language pack) like
scePlayGoGetLanguageMask reports every language. They returned an empty
bitmask, so PPSA01748 hid every text language its playgo-scenario.json
lists as a chunk language, English included.

A 2D image_sample_l through a 1D T# now takes the 1D runtime mode, as
image_sample_lz already does, instead of failing the runtime image
interface. Measured on RDNA2 (gfx1036) with tools/hw-oracle against the
same sample with DIM 1D: u inside, on and past the edges, v of 0, 0.5, 1,
-0.25 and 3, LOD -1 to 6 on a 5-level R32_FLOAT texture, point, linear and
linear-mip filtering, wrap, clamp and border addressing, and HEIGHT or
DEPTH 3. All 4725 rows matched: the 1D T# decides the addressing and v is
ignored.
The execution test samples a 5-level 1D T# with distinct mip contents at
LODs -1 to 6, fractional ones included, with u inside, on and past the
edges, under point filtering with wrap and clamp and linear filtering with
linear mips and wrap, clamp and border addressing. Every result must match
the same image_sample_l with DIM 1D bit for bit; point-filtered results
must also be the expected texel of the expected level, and linear-mip
results the blend of the two levels the LOD selects.
On Windows every direct host import leaves the write watch, and a sampled
texture snapshot over it was compared with guest memory at every lookup:
its generation stays 0, so UnchangedSince never holds. ASTRO BOT
(PPSA21564) compared about 31 GB per 10 s at the title.
The lookup now keys such a snapshot by UntrackedHint, NewestStamp,
ForgetSerial and the recorder's newest write note, taken before the
snapshot is read or compared, as StorageTexture::compareUntracked does,
and skips the compare while the key is unchanged and no recorded work
writes the surface. The byte compare still decides after any mark.

Crimson Desert (PPSA25286) calls scePadSetVibrationMode(handle, 5)
at start-up, and main rejects any mode above 3 with
SCE_PAD_ERROR_INVALID_ARG (0x80920001). The title then carries on
with the call failed.
The modes are not documented. SharpProspero names 1 (advanced) and 2
(compatible); mode 3 was accepted for PPSA21480. The call now also
accepts 5, which a shipped title passes, and keeps rejecting the values
no title has been seen to use (4, 6 and above). The mode is stored as
before and has no other effect.

ds_add_f32 and ds_add_rtn_f32 now follow the measured hardware: both
operands are flushed to a signed zero when bit 0 of the f32 denormal field
is clear and the result when bit 1 is clear, the sum is rounded to nearest
even, a NaN data operand is stored quieted, else a NaN old value is stored
quieted, and +inf + -inf stores 0xffc00000. Measured on gfx1010 and, in
#5492, on gfx1031.
The new MemoryInfo field is stored in the shader disk cache (field count
31, minimum record 79 bytes, FormatVersion 34). The parts that depend only
on the data operand are computed once, before the CAS loop.
