An RX 6700 XT hands a geometry shader odd strip triangle i as
(i+1, i, i+2) with the last provoking vertex, which is the order the
translator already uses, and since #7374 last mode takes the flat
outputs of the program's primitives from their last index. Keep the
last-mode refusal for fans only, which reach the program as
(i+1, i+2, 0) while the hardware gives (0, i+1, i+2). TEKKEN DARK
RESURRECTION (PPSA31371) stops on such a strip draw.

A read of memory inside a stale D32 Z_X depth plane (FlushDepthPlanes) stored
the whole plane: a copy of the depth image into the mirror, MarkWholeWritten
and a write-back of every byte. In Super Meat Boy 3D (#8840) a read-only
buffer ending about 3 KiB inside a stale 3840x2160 plane makes
ShaderResources::Revalidate flush ~1000 times per 5 s, each one moving
31.9 MiB, bound by transfer bandwidth.
A depth surface now tracks its plane as 64 KiB units, each one 128x128 tile
of the mirror's block units: a stale bit and a write generation per unit
replace memoryStale and the plane-wide syncedGeneration.
- FlushDepthPlanes stores only the stale units the range overlaps: the depth
to mirror copy takes one region per unit rectangle (UnitRects, from the
mirror's slice windows), the mirror marks just those units written
(MarkUnitsWritten) and the write-back covers their hull. The other units
stay stale and the plane stays registered. Stale bits are cleared only
after the copy was recorded, and the stored units' generations advance
only when FlushPending stored them. A depth fast clear still pending at
the store rewrites the whole image, so it makes every unit stale first.
- SyncFromMemory copies from the mirror only the units the guest wrote since
their own generation (one ChangedBlocks scan; untracked memory counts as
unwritten, as WrittenSince did), so a guest write into one unit no longer
replaces GPU depth that is still unstored in the others.
- Flushes followed by a retire keep the whole-plane store: the color target
flush in Draw and a written storage view (DepthPlaneScope::Whole). The
retire of an overwritten surface in DepthSurfaceTexture first stores its
remaining stale units the guest did not write.
- A mirror without block units (APS5_NO_BLOCK_TRACKING, unaligned base)
falls back to the whole-plane copy, and APS5_DEPTH_PLANE_WHOLE_STORE=1
tracks the plane as one unit, the previous behaviour.
- DepthPlaneStoreCounts reports stores, units and bytes stored.

A draw with DB_RENDER_CONTROL.DEPTH_COPY copies one sample of the
Z_32_FLOAT depth surface into color target 0. It now runs as a compute
pass that fetches that sample and stores it into the R32 float target,
when the draw covers the whole surface without depth or stencil tests.
With COPY_CENTROID the sample is the first one the draw covers, which is
sample 0 under the full sample mask the driver requires, as radeonsi
programs its per-sample DB to CB copies.

PA_SU_SC_MODE_CNTL with POLY_MODE set to a point or line type was refused,
and every triangle was drawn filled. The state decode now takes the polygon
type of the faces that are not culled into State::polygonMode, ignores the
types when POLY_MODE is clear or the primitives are points or lines, and
keeps refusing front and back types that differ while both faces are drawn.
Points are drawn one pixel wide (PA_SU_POINT_SIZE 0x00080008 inside
PA_SU_POINT_MINMAX), the size VK_KHR_maintenance5 gives a point whose
shader does not write PointSize, and lines one pixel wide (PA_SU_LINE_CNTL).
The device enables fillModeNonSolid and maintenance5 when they are
available. The polygon mode joins the pipeline, library and draw keys and
the pipeline journal (format 5).

A store to the trimmed tail of a written buffer would be dropped instead
of failing as an alias of the render target, so only read-only buffers,
such as per-attribute vertex fetches, are trimmed.

main 7ce3b1df3e took disk-cache format 43 (#8295) for its own layout, so this
branch's format moves to 44. The request serializer stays at 42: main
still writes 41.
When a draw's stage fails to prepare, capture or recompile, the packet
worker fails the queue and the next Submit or WaitIdle rethrows the
error, which ends the title. With APS5_SKIP_REFUSED_DRAWS set,
materializeDrawStage rethrows that error as a RefusedDraw; the packet
loop skips the draw, counts it as a thrown skip, logs the shader once
per address and runs the rest of the submission. The frame then lacks
that draw. Compute refusals and errors outside the stage build fail as
before, and without the switch nothing changes.
agc_driver_draw_unsupported_buffer_type_skip_refused submits a draw
whose pixel shader is refused twice with the switch: the WRITE_DATA
after it lands both times and the color target stays untouched.
AI-assisted: yes
Debt entries name the titles they were measured on. Use the title ID, or "a retail title" where the sentence needs no identification. No technical content changes.
A geometry program with VGT_GS_OUT_PRIM_TYPE 0 (point list) was refused
as an unsupported output assembly, halting Cocoon (PPSA08766) on boot
with "VGT_GS_OUT_PRIM_TYPE other than a triangle strip, or a line strip
from a geometry program, is unsupported".
Each primitive export of an NGG point-list geometry program outputs one
point whose vertex index is stored directly in PrimitivePointIndicesEXT,
so the mesh module now declares OutputPoints with PrimitivePointIndicesEXT
for it when outputPrimitiveSize is 1. The point primitive export extracts
the 9-bit vertex index from the packed primitive export word and stores
it to the output array. A subgroup gets up to maxVertices points, with
provoking vertex 0 and point raster primitive topology.
Tested with Cocoon (PPSA08766) which now progresses past pipeline
creation and initial frame draws into gameplay.
AI-assisted: yes. Written with AI assistance and reviewed by me.
Slots 1-5 are now written by sceAgcSetStaticBuffer and the
sceAgcSetStaticQword family, so staying zero until a title writes them
is the modelled console behaviour.

Decode DB_Z_INFO.MAXMIP and DB_DEPTH_VIEW.MIPID and render into the
selected level of a 64 KiB Z_X mip chain as a surface of its own, at
the level's offset and extent from ComputeElementMipLayout, as color
target mips do. Slices of a mip chain step by the size of the whole
chain. Multisampled depth mips, other swizzles, levels in the packed
mip tail and HTILE on a mip chain still throw. LEGO Builder's
Journey (PPSA05496) stopped at its first scene on
"depth mips (DB_DEPTH_VIEW MIP_LEVEL) is unsupported".
