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.
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.

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.
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

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.

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.
The call site of PPSA21402 sets only three argument registers, so the function has no size parameter. A data chunk that runs past the buffer or ends inside a frame returns INVALID_WAVEFORM_DATA instead of being shortened. The test no longer writes padding from a string literal.
Write the 2-dword CLEAR_STATE (0x12) packet with a 4-bit command, the
packet the driver already validates and executes by restoring the
initial context registers.

Write SET_CONFIG_REG (0x68) packets like the context, shader and user
config register setters: one register from a ShaderRegister, or a range
of values at an offset.

Patch the mask of a wait packet like sceAgcWaitRegMemPatchReference
patches its reference: a 32-bit value written to the low mask word of a
32- or 64-bit WAIT_REG_MEM, rejected above 32 bits.

The end-of-shader action is written by an inline SDK builder as a
RELEASE_MEM packet, so the size is the 32 bytes that
sceAgcCbReleaseMem writes and that sceAgcAcbQueueEndOfShaderActionGetSize
already returns.

The reverb was a Freeverb-style approximation. It now follows the PS4
firmware 11.00 libSceNgs2.sprx, read and checked against its output: the
input mixed to mono with the library's fixed gains, a 14400-sample buffer
with four reflection taps from the reflection pattern tables and a late
feed, sixteen damped comb filters with a pre-emphasis stage, a signed
selection of combs and four allpasses per output channel, a two-pole room
HF filter, and the library's parameter clamps, crossfades and setup
defaults. The test values are the PS4 library's own output.

20 of the 31 NIDs have names in shadPS4's aerolib list. They are declared
under those names; POSIX sleep is implemented. The NpPartner001 and Psml
MFSR2 exports stay unnamed.

A pixel, vertex or tessellation stage whose wave is wider than the host
subgroup runs one guest lane per invocation, so lanes at or above the
subgroup size have no invocation. v_readlane_b32 still shuffled from
them, which Vulkan leaves undefined; a wave64 pixel minimum loop that
reads lanes 31 and 63 can then wait for a value no live lane holds and
hang the GPU.
At one lane per invocation outside compute, a v_readlane_b32 of a
constant lane at or above the host subgroup size, and v_permlanex16_b32
on a subgroup of 16 lanes or fewer, now fail SPIR-V emission. Lanes in
registers still build, so s_ff1_i32_b64 waterfalls are unaffected,
and neither check applies to compute or to two lanes per invocation.
v_permlane16_b32 and v_permlanex16_b32 take the source lane's EXEC from
a ballot, as DPP does, instead of a shuffle from a possibly inactive
invocation.
GFX10 image format 30 (10_11_11_UNORM: X and Y are unorm11 in bits
0-21, Z is unorm10 in bits 22-31, per Mesa's gfx10 tables) has no
Vulkan format, so its sampled and storage descriptors threw at decode.
Format 30 now takes the R32_UINT route of 10_11_11_UINT: the driver
binds the raw dwords as R32_UINT and the shader extracts each field and
converts it with the buffer format helpers (NormalizeFormatComponent on
loads, EmitFormatStoreComponent on stores); DST_SEL 1 reads 1.0f.
Samples, gathers, LOD queries, 16-bit data and loads or stores whose
DST_SEL names the missing W channel throw.
Converted textures are now viewed with an identity component mapping,
since the shader applies DST_SEL itself: a 10_11_11_UINT view whose X
selector was not X lost the packed dword. DCC clear codes 0001 and 1110
of a converted texture throw instead of filling one R32_UINT channel.
