video_core: Implement an arm64 shader-jit backend (#7002)
* externals: Add oaksim submodule

Used for emitting ARM64 assembly

* common: Implement aarch64 ABI

Utilize oaknut to implement a stack frame.

* tests: Allow shader-jit tests for x64 and a64

Run the shader-jit tests for both x86_64 and arm64 targets

* video_core: Initialize arm64 shader-jit backend

Passes all current unit tests!

* shader_jit_a64: protect/unprotect memory when jit-ing

Required on MacOS. Memory needs to be fully unprotected and then
re-protected when writing or there will be memory access errors on
MacOS.

* shader_jit_a64: Fix ARM64-Imm overflow

These conditionals were throwing exceptions since the immediate values
were overflowing the available space in the `EOR` instructions. Instead
they are generated from `MOV` and then `EOR`-ed after.

* shader_jit_a64: Fix Geometry shader conditional

* shader_jit_a64: Replace `ADRL` with `MOVP2R`

Fixes some immediate-generation exceptions.

* common/aarch64: Fix CallFarFunction

* shader_jit_a64: Optimize `SantitizedMul`

Co-authored-by: merryhime <merryhime@users.noreply.github.com>

* shader_jit_a64: Fix address register offset behavior

Based on https://github.com/citra-emu/citra/pull/6942
Passes unit tests.

* shader_jit_a64: Fix `RET` address offset

A64 stack is 16-byte aligned rather than 8. So a direct port of the x64
code won't work. Fixes weird branches into invalid memory for any
shaders with subroutines.

* shader_jit_a64: Increase max program size

Tuned for A64 program size.

* shader_jit_a64: Use `UBFX` for extracting loop-state

Co-authored-by: JosJuice <JosJuice@users.noreply.github.com>

* shader_jit_a64: Optimize `SUB+CMP` to `SUBS`

Co-authored-by: JosJuice <JosJuice@users.noreply.github.com>

* shader_jit_a64: Optimize `CMP+B` to `CBNZ`

Co-authored-by: JosJuice <JosJuice@users.noreply.github.com>

* shader_jit_a64: Use `FMOV` for `ONE` vector

Co-authored-by: JosJuice <JosJuice@users.noreply.github.com>

* shader_jit_a64: Remove x86-specific documentation

* shader_jit_a64: Use `UBFX` to extract exponent

Co-authored-by: JosJuice <JosJuice@users.noreply.github.com>

* shader_jit_a64: Remove redundant MIN/MAX `SRC2`-NaN check

Special handling only needs to check SRC1 for NaN, not SRC2.
It would work as follows in the four possible cases:

No NaN: No special handling needed.
Only SRC1 is NaN: The special handling is triggered because SRC1 is NaN, and SRC2 is picked.
Only SRC2 is NaN: FMAX automatically picks SRC2 because it always picks the NaN if there is one.
Both SRC1 and SRC2 are NaN: The special handling is triggered because SRC1 is NaN, and SRC2 is picked.

* shader_jit/tests:: Add catch-stringifier for vec2f/vec3f

* shader_jit/tests: Add Dest Mask unit test

* shader_jit_a64: Fix Dest-Mask `BSL` operand order

Passes the dest-mask unit tests now.

* shader_jit_a64: Use `MOVI` for DestEnable mask

Accelerate certain cases of masking with MOVI as well

Co-authored-by: JosJuice <JosJuice@users.noreply.github.com>

* shader_jit/tests: Add source-swizzle unit test

This is not expansive. Generating all `4^4` cases seems to make Catch2
crash. So I've added some component-masking(non-reordering) tests based
on the Dest-Mask unit-test and some additional ones to test
broadcasts/splats and component re-ordering.

* shader_jit_a64: Fix swizzle index generation

This was still generating `SHUFPS` indices and not the ones that we wanted for the `TBL` instruction. Passes all unit tests now.

* shader_jit/tests: Add `ShaderSetup` constructor to `ShaderTest`

Rather than using the direct output of `CompileShaderSetup` allow a
`ShaderSetup` object to be passed in directly.  This enabled the ability
emit assembly that is not directly supported by nihstro.

* shader_jit/tests: Add `CALL` unit-test

Tests nested `CALL` instructions to eventually reach an `EX2`
instruction.

EX2 is picked in particular since it is implemented as an even deeper
dispatch and ensures subroutines are properly implemented between `CALL`
instructions and implementation-calls.

* shader_jit_a64: Fix nested `BL` subroutines

`lr` was getting writen over by nested calls to `BL`, causing undefined
behavior with mixtures of `CALL`, `EX2`, and `LG2` instructions.

Each usage of `BL` is now protected with a stach push/pop to preserve
and restore teh `lr` register to allow nested subroutines to work
properly.

* shader_jit/tests: Allocate generated tests on heap

Each of these generated shader-test objects were causing the stack to
overflow.  Allocate each of the generated tests on the heap and use
unique_ptr so they only exist within the life-time of the `REQUIRE`
statement.

* shader_jit_a64: Preserve `lr` register from external function calls

`EMIT` makes an external function call, and should be preserving `lr`

* shader_jit/tests: Add `MAD` unit-test

The Inline Asm version requires an upstream fix:
https://github.com/neobrain/nihstro/issues/68

Instead, the program code is manually configured and added.

* shader_jit/tests: Fix uninitialized instructions

These `union`-type instruction-types were uninitialized, causing tests
to indeterminantly fail at times.

* shader_jit_a64: Remove unneeded `MOV`

Residue from the direct-port of x64 code.

* shader_jit_a64: Use `std::array` for `instr_table`

Add some type-safety and const-correctness around this type as well.

* shader_jit_a64: Avoid c-style offset casting

Add some more const-correctness to this function as well.

* video_core: Add arch preprocessor comments

* common/aarch64: Use X16 as the veneer register

https://developer.arm.com/documentation/102374/0101/Procedure-Call-Standard

* shader_jit/tests: Add uniform reading unit-test

Particularly to ensure that addresses are being properly truncated

* common/aarch64: Use `X0` as `ABI_RETURN`

`X8` is used as the indirect return result value in the case that the
result is bigger than 128-bits. Principally `X0` is the general-case
return register though.

* common/aarch64: Add veneer register note

`LR` is generally overwritten by `BLR` anyways, and would also be a safe
veneer to utilize for far-calls.

* shader_jit_a64: Remove unneeded scratch register from `SanitizedMul`

* shader_jit_a64: Fix CALLU condition

Should be `EQ` not `NE`. Fixes the regression on Kid Icarus.
No known regressions anymore!

Rasterizer cache refactor (#6375)
* rasterizer_cache: Remove custom texture code

* It's a hacky buggy mess, will be reimplemented later when the cache is in a better state

* rasterizer_cache: Refactor surface upload/download

* Switch to the texture_codec header which was written as part of the vulkan backend by steveice and me

* Move most of the upload logic to the rasterizer cache and out of the surface object

* Scaled uploads/downloads have been disabled for now since they require more runtime infrastructure

* rasterizer_cache: Refactor runtime interface

* Remove aspect enum which is the same as SurfaceType

* Replace Subresource with specific structures for each operation (blit/copy/clear). This mimics moderns APIs vulkan much better

* Pass the surface to the runtime instead of the texture

* Implement CopyTextures with glCopyImageSubData which is available on 4.3 and gles.
  This function also has an overload for cubes which will be removed later.

* rasterizer_cache: Move texture allocation to the runtime

* renderer_opengl: Remove TextureDownloaderES

* It's overly compilcated and unused at the moment. Will be replaced with a simple compute shader in a later commit

* rasterizer_cache: Split CachedSurface

* This commit splits CachedSurface into two classes, SurfaceBase which contains the backend agnostic functions and Surface which is the opengl specific part

* For now the cache uses the opengl surface directly and there are a few ugly casts with watchers, those will be taken care of when the template convertion and watcher removal are added respectively

* rasterizer_cache: Move reinterpreters to the runtime

* rasterizer_cache: Move some pixel format function to the cpp file

* rasterizer_cache: Common texture acceleration functions

* They don't contain any backend specific code so they shouldn't be duplicated

* rasterizer_cache: Remove BlitSurfaces

* It's better to prefer copy/blit in the caller anyway

* rasterizer_cache: Only allocate needed levels

* rasterizer_cache: Move texture runtime out of common dir

* Also shorten the util header filename

* surface_params: Cleanup code

* Add more comments, organize it a bit etc

* rasterizer_cache: Move texture filtering to the runtime

* rasterizer_cache: Move to VideoCore

* renderer_opengl: Reimplement scaled uploads/downloads

* Instead of looking up for temporary textures, each allocation now contains both a scaled and unscaled handle
  This allows the scale operations to be done inside the surface object itself and improves performance in general

* In particular the scaled download code has been expanded to use ARB_get_texture_sub_image when possible
  which is faster and more convenient than glReadPixels. The latter is still relevant for OpenGLES though.

* Finally allocations are now given a handy debug name that can be viewed from renderdoc.

* rasterizer_cache: Remove global state

* gl_rasterizer: Abstract common draw operations to Framebuffer

* This also allows to cache framebuffer objects instead of always swapping the textures, something that particularly benefits mali gpus

* rasterizer_cache: Implement multi-level surfaces

* With this commit the cache can now directly upload and use mipmaps
  without needing to sync them with watchers. By using native mimaps
  directly this also adds support for mipmap for cube

* Texture cubes have also been updated to drop the watcher requirement

* host_shaders: Add CMake integration for string shaders

* Improves build time shader generation making it much less prone to errors.
  Also moves the presentation shaders here to avoid embedding them to the cpp file.

* Texture filter shaders now make explicit use of uniform bindings for better vulkan compatibility

* renderer_opengl: Emulate lod bias in the shader

* This way opengles can emulate it correctly

* gl_rasterizer: Respect GL_MAX_TEXTURE_BUFFER_SIZE

* Older Bifrost Mali GPUs only support up to 64kb texture buffers. Citra would try to allocate a much larger buffer the first 64kb of which would work fine but after that the driver starts misbehaving and showing various graphical glitches

* rasterizer_cache: Cleanup CopySurface

* renderer_opengl: Keep frames synchronized when using a GPU debugger

* rasterizer_cache: Rename Surface to SurfaceRef

* Makes it clear that surface is a shared_ptr and not an object

* rasterizer_cache: Cleanup

* Move constructor to the top of the file

* Move FindMatch to the top as well and remove the Invalid flag which was redudant;
  all FindMatch calls used it expect from MatchFlags::Copy which ignores it anyway

* gl_texture_runtime: Make driver const

* gl_texture_runtime: Fix RGB8 format handling

* The texture_codec header, being written with vulkan in mind converts RGB8 to RGBA8. The backend wasn't adjusted to account for this though and treated the data as RGB8.

* Also remove D16 convertions, both opengl and vulkan are required to support this format so these are not needed

* gl_texture_runtime: Reduce state switches during FBO blits

* glBlitFramebuffer is only affected by the scissor rectangle so just disable scissor testing instead of resetting our entire state

* surface_params: Prevent texcopy that spans multiple levels

* It would have failed before as well, with multi-level surfaces it triggers the assert though

* renderer_opengl: Centralize texture filters

* A lot of code is shared between the filters thus is makes it sense to centralize them

* Also fix an issue with partial texture uploads

* Address review comments

* rasterizer_cache: Use leading return types

* rasterizer_cache: Cleanup null checks

* renderer_opengl: Add additional logging

* externals: Actually downgrade glad

* For some reason I missed adding the files to git

* surface_params: Do not check for levels in exact match

* Some games will try to use the base level of a multi level surface. Checking for levels forces another surface to be created and a copy to be made which is both unncessary and breaks custom textures

emufan4568 17ad594a62 rasterizer_cache: Introduce TextureRuntime and separate CachedSurface
* This commit aims to both continue the rasterizer cache cleanup by
  separating CachedSurface into a dedicated header and to start weeding
  out the raw OpenGL code from the cache.

* The latter is achieved by abstracting most texture operations in a new
  class called TextureRuntime. This has many benefits such as making it easier
  to port the functionality to other graphics APIs and the removal of the need
  to pass (read/draw) framebuffer handles everywhere. The filterer and
  reinterpreter get their own sets of FBOs due to this, something that
  might be a performance win since it reduces the state switching
  overhead on the runtime FBOs.

video_core/renderer_opengl/gl_rasterizer_cache: Create Format Reinterpretation Framework (#5170)
* video_core/renderer_opengl/gl_rasterizer_cache: Create Format Reinterpretation Framework

Adds RGBA4 -> RGB5A1 reinterpretation commonly used by virtual console
If no matching surface can be found, ValidateSurface checks for a surface in the cache which is reinterpretable to the requested format.
If that fails, the cache is checked for any surface with a matching bit-width. If one is found, the region is flushed.
If not, the region is checked against dirty_regions to see if it was created entirely on the GPU.
If not, then the surface is flushed.

Texture Filtering v2 (#5166)
* video_core/renderer_opengl: Move SurfaceParams into its own file

Some of its enums are needed outside of the rasterizer cache
and trying to use it caused circular dependencies.

* video_core/renderer_opengl: Overhaul the texture filter framework

This should make it less intrusive.
Now texture filtering doesn't have any mutable global state.
The texture filters now always upscale to the internal rendering resolution.
This simplifies the logic in UploadGLTexture and it simply takes the role of BlitTextures at the end of the function.
This also prevent extra blitting required when uploading to a framebuffer surface with a mismatched size.

* video_core/renderer_opengl: Use generated mipmaps for filtered textures

The filtered guest mipmaps often looked terrible.

* core/settings: Remove texture filter factor

* sdl/config: Remove texture filter factor

* qt/config: Remove texture filter factor

video_core, core: Move pixel download to its own thread
This uses the mailbox model to move pixel downloading to its own thread, eliminating Nvidia's warnings and (possibly) making use of GPU copy engine.

To achieve this, we created a new mailbox type that is different from the presentation mailbox in that it never discards a rendered frame.

Also, I tweaked the projection matrix thing so that it can just draw the frame upside down instead of having the CPU flip it.

Markus Wick 392547a97c gl_resource_manager: Split implementations in .cpp file
Those implementations are quite costly, so there is no need to inline them to the caller.
Ressource deletion is often a performance bug, so in this way, we support to add breakpoints to them.

wwylele 0f35755572 pica/command_processor: build geometry pipeline and run geometry shader
The geometry pipeline manages data transfer between VS, GS and primitive assembler. It has known four modes:
 - no GS mode: sends VS output directly to the primitive assembler (what citra currently does)
 - GS mode 0: sends VS output to GS input registers, and sends GS output to primitive assembler
 - GS mode 1: sends VS output to GS uniform registers, and sends GS output to primitive assembler. It also takes an index from the index buffer at the beginning of each primitive for determine the primitive size.
 - GS mode 2: similar to mode 1, but doesn't take the index and uses a fixed primitive size.
hwtest shows that immediate mode also supports GS (at least for mode 0), so the geometry pipeline gets refactored into its own class for supporting both drawing mode.
In the immediate mode, some games don't set the pipeline registers to a valid value until the first attribute input, so a geometry pipeline reset flag is set in `pipeline.vs_default_attributes_setup.index` trigger, and the actual pipeline reconfigure is triggered in the first attribute input.
In the normal drawing mode with index buffer, the vertex cache is a little bit modified to support the geometry pipeline. Instead of OutputVertex, it now holds AttributeBuffer, which is the input to the geometry pipeline. The AttributeBuffer->OutputVertex conversion is done inside the pipeline vertex handler. The actual hardware vertex cache is believed to be implemented in a similar way (because this is the only way that makes sense).
Both geometry pipeline and GS unit rely on states preservation across drawing call, so they are put into the global state. In the future, the other three vertex shader units should be also placed in the global state, and a scheduler should be implemented on top of the four units. Note that the current gs_unit already allows running VS on it in the future.
