374c2194d4 video_core: Address various UE bugs (#3559)
* vk_rasterizer: Reorder image query in fast clear elimination

Fixes missing clears when a texture is being cleared using this method but never actually used for rendering purposes by ensuring the texture cache has at least a chance to register cmask

* shader_recompiler: Partial support for ANCILLARY_ENA

* pixel_format: Add number conversion of BC6 srgb format

* texture_cache: Support aliases of 3D and 2D array images

Used be UE to render its post processing LUT

* pixel_format: Test BC6 srgb as unorm

Still not sure what is up with snorm/unorm can be useful to have both actions to compare for now

* video_core: Use attachment feedback layout instead of general if possible

UE games often do mipgen passes where the previous mip of the image being rendered to is bound for reading. This appears to cause corruption issues so use attachment feedback loop extension to ensure correct output

* renderer_vulkan: Improve feedback loop code

* Set proper usage flag for feedback loop usage
* Add dynamic state extension and enable it for color aspect when necessary
* Check if image is bound instead of force_general for better code consistency

* shader_recompiler: More proper depth export implementation

* shader_recompiler: Fix bug in output modifiers

* shader_recompiler: Fix sampling from MSAA images

This is not allowed by any graphics API but seems hardware supports it somehow and it can be encountered. To avoid glitched output translate to to a texelFetch call on sample 0

* clang format

* image: Add back missing code

* shader_recompiler: Better ancillary implementation

Now is implemented with a custom attribute that is constant propagated depending on which parts of it are extracted. It will assert if an unknown part is used or if the attribute itself is not removed by dead code elim

* copy_shader: Ignore not enabled export channels

* constant_propagation: Invalidate ancillary after successful elimination

* spirv: Fix f11/f10 conversion to f32

* shader_recompiler: Replace buffer pulling with attribute divisor for instance step rates

* flatten_extended_userdata: Remove special step rate buffer handling

* Review comments

* spirv_emit_context: Name all instance rate attribs properly

* spirv: Merge ReadConstBuffer again

template function only has 1 user now

* attribute: Add missing attributes

* translate: Reimplement step rate instance id

* Resolve validation warnings

3c0c921ef5 Tessellation (#1528)
* shader_recompiler: Tessellation WIP

* fix compiler errors after merge

DONT MERGE set log file to /dev/null

DONT MERGE linux pthread bb fix

save work

DONT MERGE dump ir

save more work

fix mistake with ES shader

skip list

add input patch control points dynamic state

random stuff

* WIP Tessellation partial implementation. Squash commits

* test: make local/tcs use attr arrays

* attr arrays in TCS/TES

* dont define empty attr arrays

* switch to special opcodes for tess tcs/tes reads and tcs writes

* impl tcs/tes read attr insts

* rebase fix

* save some work

* save work probably broken and slow

* put Vertex LogicalStage after TCS and TES to fix bindings

* more refactors

* refactor pattern matching and optimize modulos (disabled)

* enable modulo opt

* copyright

* rebase fixes

* remove some prints

* remove some stuff

* Add TCS/TES support for shader patching and use LogicalStage

* refactor and handle wider DS instructions

* get rid of GetAttributes for special tess constants reads. Immediately replace some upon seeing readconstbuffer. Gets rid of some extra passes over IR

* stop relying on GNMX HsConstants struct. Change runtime_info.hs_info and some regs

* delete some more stuff

* update comments for current implementation

* some cleanup

* uint error

* more cleanup

* remove patch control points dynamic state (because runtime_info already depends on it)

* fix potential problem with determining passthrough

3c90b8ac00 video_core: Bringup some basic functionality (#145)
* video_core: Remove hack in rasterizer

* The hack was to skip the first draw as the display buffer had not been created yet and the texture cache couldn't create one itself. With this patch it now can, using the color buffer parameters from registers

* shader_recompiler: Implement attribute loads/stores

* video_core: Add basic vertex, index buffer handling and pipeline caching

* externals: Make xxhash lowercase
