A new entry next to the FORCE_DEGAMMA entry. shadPS4 converts the filtered texel of every non-sRGB format to linear and fpPS4 documents the bit as applied after filtering regardless of format; here a forcing sampler reads the texture through its sRGB view, so the conversion happens before filtering, for formats that are not sRGB and not on a fixed list. PS4 (GCN) behaviour only; nothing is claimed about the console.

A cached address space keeps a heap mirror whose range has left the write watch while the budget refuses the range's import, and such a mirror is copied in full at every build. When the budget is held by imports a build uses every time, as the pieces #8380 imports of a heap over the budget are, the import was refused at every build, each refusal counted, and every build copied the whole range (about 1.1 GiB in Astro Bot). The check now evicts for that import as the copy cap does: idle imports, and imports a heap mirror can replace that no build in progress holds.
An address-based build that copies a range the budget refused and no mirror serves (a range outside the write watch, or not releasable) evicts idle imports when the copy would pass APS5_ADDRESS_COPY_MAX_MIB. Imports used in the current or the previous frame (before two frames have ended, within the last 256 lookups) never count as idle, so once a build uses an import every frame, as it does for the pieces #8380 imports of a heap over the budget or a whole heap imported before, nothing can be evicted and the build aborts. That eviction now also takes imports the build has not taken yet whose single range is releasable and write-watched: the build then serves that range from a heap mirror instead.
The barycentric tessellation path refused any draw with the primitive
restart bit set. A non-indexed strip ignores the bit, and on a device
without VK_EXT_primitive_topology_list_restart a list never restarts on
the host, since its indices are compacted on the CPU first, so both now
take the patches. Indexed strips with primitive restart still throw,
now also in Graphics::Draw, which knows the draw is indexed.
Patch-list pipelines never enable primitive restart, which Vulkan does not
allow for them without primitiveTopologyPatchListRestart.

The Windows and macOS branches and a hardware GPU's output are not
checked, and the list of required Vulkan items is kept in step with
VulkanDevice.cpp by hand.
Late-added ranges and write-watched blocks are read through the same
host-only-aware read as the snapshot, so a CPU store over a guarded
multisample target no longer aborts a capture. The read is a helper
tested for ranges in the middle, at either edge, overlapping and
outside a block, and against a native target and its neighbor.

A capture snapshot read every committed block through the coherent path,
which refuses memory under a multisampled color target, its FMASK or
native multisample depth whose samples exist only on the host, so the
capture stopped there. The snapshot now writes those bytes as zeros,
counts them as host_only_sample_bytes in capture.json and adds a
warning, and the replay starts those targets without their earlier
contents.

A cube T# whose last array slice is 6n - 1 is a cube array of n cubes.
The depth plane path accepted one cube only (last array 0 or 5) and
threw for the rest; it now gathers all 6n slices into the 2D array
view, as the texture path already lays cubes out. The refusal message
also names the last array slice and the copy format.
Uncharted 4's orphanage samples a two-cube D32 shadow array this way.

The stencil plane text named the game; debt entries carry title IDs
only. It also took the depth plane entry past the 1000-character limit,
so it now has an entry of its own.
AI-assisted: yes
Only the depth plane of a depth surface reached guest memory: stencil
lived in the host image alone. A title that moves stencil with buffer
copies read stale bytes from the source plane, and the destination
surface never saw what the copy wrote. Uncharted 4 clears its G-buffer
stencil plane with a fill, then copies it into the lighting depth
target and on into last frame's planes with a buffer copy kernel every
frame; its lighting kept the stencil marks of earlier frames, so
characters left trails and the image doubled while the camera moved.
The stencil plane of a single-sample surface with the 64 KiB Z swizzle
is now marked drawn when the surface is bound, stored whole when a read
overlaps it (FlushDepthPlanes, like the depth plane) and reloaded from
guest memory when a collected guest write changed it before the surface
is bound or its stencil sampled, unless a stencil clear is pending.
agc_driver_stencil_plane_memory draws stencil, reads the plane through
FlushDepthPlanes, then writes it from the CPU and tests it with stencil
EQUAL; it fails without the change.

PS4 color and depth targets, PS4 graphics EOP events, and the PS4 tile
modes (1D/2D thin and display, depth with tile split, PRT, linear
general) on the AGC executor, with a GPU detiler for every mode.
Textures sampled over the padded corner of a render target are GPU block
copies, and the PS4 SDK pattern-fill compute kernel runs as a GPU fill
when it repeats one dword, so render targets and HTILE are cleared
without a CPU drain. Two-dword patterns keep running the kernel: as
fills, Limbo's clears of its 64-bit target made its gameplay advance
about half as far per frame.
Tests cover the tiling equations against addrlib formulas, the GPU
detiler for every mode and element size, and the fill ranges.
A PS5 measurement already recorded in the debt note shows queue 0x58 succeeds; raise the exclusive SubmissionQueueEnd and cover it in agc_driver_tests.
Main took request serialization version 48 for the fragment barycentric
built-ins flag (#9193). The depth export clamp bounds are now written at
version 49 and read only for versions from 49, so a version 48 request as main
writes it still decodes, with default bounds. Tests: version 49 is the
emitted prefix, 50 the first unsupported one, a depth exporting request
without its bounds decodes at 48, 47 and 46 (the last two without main's
barycentric byte), and a version 48 two-sample dithered request decodes as
written.
