The resource tracker refused a program's 33rd distinct V# with "buffer
resource limit exceeded". The 32 was a recompiler constant, not a
Vulkan limit: every buffer is one constant-indexed element of the guest
buffers binding, which ShaderResources checks against the device's
storage-buffer limits.
Drop ShaderInfo::MaxBuffers and the tracker's refusal, and size the
SPIR-V emitter's per-buffer offset list from the binding layout. When
the user data and offsets do not fit in the push constants, they all go
to the shader data buffer as before. ShaderResources counted only
storage buffers against maxPerStageResources (200 on Intel UHD) and now
adds the stage's sampled and storage images.
agc_driver_many_buffers reads and writes 52 and 124 buffers, and
agc_driver_graphics rejects buffers plus an image above the limit.
An S# with FILTER_MODE (word0 bits 29-30) set threw in
DecodeSamplerResource. Modes 1 and 2 now map to Vulkan's MIN and MAX
sampler reduction through VK_EXT_sampler_filter_minmax, which the device
enables when it reports both filterMinmax properties; mode 3 throws.
Min/max still throws with anisotropy, a linear mip filter (lavapipe and
NVIDIA disagree there), depth comparison, color-texture compare
emulation, and, in PointFilteredSamplerWord (S# words 0 and 2), when it
filters between texels or mips of an image the recompiler point-samples.
A texture sampled through a linear min/max sampler needs
SAMPLED_IMAGE_FILTER_MINMAX on its view format; the image-sampler pairs
travel in DescriptorBinding::imageSamplers (shader disk cache format 5).
Adds the agc_driver_image_sample_reduction GPU test and extends the
sampler, emulated color compare and disk cache tests.
GFX10 format 6 (8_SINT) T#s threw "sampled image descriptor uses an
unsupported format": neither the recompiler's format table nor the
driver's texture format table had a row for it. Format 6 now reads as
a SINT image through an R8_SINT view, so image_load sign-extends each
texel (0x80 reads -128) and image-table entries of format 6 decode.
8_SINT storage still throws.
RADV (Mesa 26.0 and later) initialises a FREE_DESCRIPTOR_SET pool's
allocator with bo_size + RADV_POOL_HEAP_OFFSET as its size, so a set can
be placed up to 32 bytes past the pool's buffer. The chain pools are
0x26000 bytes, a page multiple, so a set at the end of a full pool has
its last descriptors on an unmapped page: the CPU descriptor write
faults, or the shader's scalar load raises a GPU page fault and the ring
is reset.
Two more storage buffer descriptors make the pool 0x26020 bytes; the
buffer's last page then holds those 32 bytes.

libSceAvPlayer.native/Export.cpp was a byte-identical copy of
libSceAvPlayer/Export.cpp. Point add_sce_avplayer_library at the guest
directory's Export.cpp, as the Audiodec and Font library functions do, and
remove the copy.

Nine SPIR-V backend sources each defined an identical FailEmit in an
anonymous namespace. Declare it once in SpirvEmitterHelpers.hpp and
define it in SpirvEmitterHelpers.cpp; the message is unchanged.

CB_COLOR_INFO format 1 with number type 6 (8_SRGB) threw at decode.
It now decodes as R8_SRGB with component swap 0; the other swaps and
8_8_SRGB still throw.
A device that cannot attach and blend R8_SRGB (NVIDIA, lavapipe)
renders a resident 8_SRGB target through an RGBA8_SRGB view of an
RGBA8 copy of its R8 image: the image is blitted in before the pass
and back when the pass ends, and the write mask keeps R only, so the
encode, decode and blend are the device's sRGB attachment rules.
APS5_SRGB_ATTACHMENT_PROXY=1 forces the copy. Linear, mipmapped and
3D 8_SRGB targets throw on such a device.
PPSA26344 renders its G-buffer slot 5 and a multiply-blend pass into
8_SRGB targets.
Mount, unmount, param, icon and mount-info calls read and wrote the
global mount slot table without a lock, so two threads mounting at
once could take the same slot and one would later fail to unmount its
own mount point. Guard the table with a mutex and make the initialization
count atomic.

LEGO Horizon Adventures imports 19 functions that no library exports
and no open pull request adds, so it fails eager binding. They are
declared as throwing stubs. The two libSceAjmWVorbis imports have no
known name and are exported by NID from libSceAjm.native.

A title maps direct memory with protection 0x3f2, which adds bits
0x100 and 0x200 to the CPU, GPU and AMPR bits, and the mapping threw.
They are the audio coprocessor (ACP) read and write bits, as named in
the KytyPS5 and etaHEN headers. The coprocessor work runs on the host
CPU, so they map to host read and read/write access like the GPU bits.

Return the version 0 internal register defaults, the internal
counterpart of sceAgcGetRegisterDefaults.

A stage's user data registers are read for the count in its RSRC2
(COMPUTE_PGM_RSRC2 for compute). A register the title never wrote no
longer refuses the draw or dispatch: it reads 0, as Kyty and SharpEmu
read it and as AMD PAL and Mesa initialize the user data registers.

A BDA dword read whose span the probe rejects falls back to four byte
lookups with a branch each, and every fault was recorded inline with a
compare-exchange and seven stores. Both were copied into every read
site and both wave64 lane halves, so one large compute program grows
to about a million SPIR-V words and spends about 95 s in
vkCreateComputePipelines.
Faults are now recorded by one DontInline function, record_bda_fault,
and the byte fallback of a dword is read_bda_dword_bytes, in a stop
and a coherent variant, returning the value and whether the invocation
stops. Read order, fault reasons, pcs, Volatile and the stop behaviour
are unchanged, and so is the probe path.
The mixing stage threw when a mastering voice and its render buffer had different channel counts. A 2-channel voice is now mixed into the first two channels of a 6- or 8-channel buffer; other mismatches still throw.
Driver::RegisterShader required the Shader header at an 8-byte
boundary (alignof(Shader)) and read its fields through the pointer.
PPSA26344 uses its shader packs in place: its compute shader objects
point at headers 4 and 1 bytes past an 8-byte boundary, so the first
sceAgcCreateShader of such a header threw "null or misaligned address".
The header is now checked for null and readable memory at any
address, and its fixed fields and the registers the trace prints are
copied out with memcpy. The code address must still be 256-byte
aligned, and the header and size checks are unchanged. The console's
rule is unknown and is listed in TechnicalDebt.
