image_atomic_* with a two-dword data mask (four for cmpswap) is the
64-bit form of an integer image atomic. The decoder rejected it with
"invalid MIMG data mask". PPSA14632 (Unreal Engine) uses
image_atomic_umax this way in a compute shader during its first frames.
Swap, add, sub, signed and unsigned min/max, and, or, xor and cmpswap
now decode with 64-bit data and translate to new ImageAtomic*64 IR
opcodes. An image updated by them gets its own descriptor binding
range, declared as an R64ui image of 64-bit integers, and the module
uses Int64ImageEXT from SPV_EXT_shader_image_int64. The driver enables
shaderImageInt64Atomics when the device offers it and binds an
R64_UINT view of the 32_32 UINT, SINT or FLOAT surface. Without the
feature, recompiling such a shader throws.
64-bit inc, dec and the float atomics still throw, as does any other
access in the same shader to an image it updates with 64-bit atomics.
The new agc_driver_image_atomics64 test runs every operation on 32_32
UINT, SINT and FLOAT surfaces and checks the returned and stored values
against edge cases across the dword boundary.

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.
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 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.
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.

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.

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.
RackGetInfo reports the rack's handles, buffer, id, uid, option limits,
render count and active voices. VoiceGetPortInfo reports a port's matrix,
volume and destination. VoiceQueryInfo answers info id 0x4001 with the
voice channel count and throws for other ids. Assumptions are recorded in
TechnicalDebt.
