* video_core: Reimplement the buffer cacheReinUsesLisp2021-02-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reimplement the buffer cache using cached bindings and page level granularity for modification tracking. This also drops the usage of shared pointers and virtual functions from the cache. - Bindings are cached, allowing to skip work when the game changes few bits between draws. - OpenGL Assembly shaders no longer copy when a region has been modified from the GPU to emulate constant buffers, instead GL_EXT_memory_object is used to alias sub-buffers within the same allocation. - OpenGL Assembly shaders stream constant buffer data using glProgramBufferParametersIuivNV, from NV_parameter_buffer_object. In theory this should save one hash table resolve inside the driver compared to glBufferSubData. - A new OpenGL stream buffer is implemented based on fences for drivers that are not Nvidia's proprietary, due to their low performance on partial glBufferSubData calls synchronized with 3D rendering (that some games use a lot). - Most optimizations are shared between APIs now, allowing Vulkan to cache more bindings than before, skipping unnecesarry work. This commit adds the necessary infrastructure to use Vulkan object from OpenGL. Overall, it improves performance and fixes some bugs present on the old cache. There are still some edge cases hit by some games that harm performance on some vendors, this are planned to be fixed in later commits.
* video_core: Remove unnecessary enum class casting in logging messagesLioncash2020-12-071-20/+14
| | | | | | | fmt now automatically prints the numeric value of an enum class member by default, so we don't need to use casts any more. Reduces the line noise a bit.
* video_core: Resolve more variable shadowing scenarios pt.2Lioncash2020-12-051-5/+5
| | | | | | | Migrates the video core code closer to enabling variable shadowing warnings as errors. This primarily sorts out shadowing occurrences within the Vulkan code.

| * shader/other: Fix hardcoded value in S2R INVOCATION_INFOReinUsesLisp2020-05-301-1/+1
| | | | | | | | | | | | | | | | | | | | Geometry shaders built from Nvidia's compiler check for bits[16:23] to be less than or equal to 0 with VSETP to default to a "safe" value of 0x8000'0000 (safe from hardware's perspective). To avoid hitting this path in the shader, return 0x00ff'0000 from S2R INVOCATION_INFO. This seems to be the maximum number of vertices a geometry shader can emit in a primitive.

| * shader/other: Implement BAR.SYNC 0x0ReinUsesLisp2020-05-221-0/+5
| | | | | | | | | | Trivially implement this particular case of BAR. Unless games use OpenCL or CUDA barriers, we shouldn't hit any other case here.
* | shader/other: Implement thread comparisons (NV_shader_thread_group)ReinUsesLisp2020-05-221-0/+21
|/ | | | | | | | | | | Hardware S2R special registers match gl_Thread*MaskNV. We can trivially implement these using Nvidia's extension on OpenGL or naively stubbing them with the ARB instructions to match. This might cause issues if the host device warp size doesn't match Nvidia's. That said, this is unlikely on proper shaders. Refer to the attached url for more documentation about these flags. https://www.khronos.org/registry/OpenGL/extensions/NV/NV_shader_thread_group.txt

|/ | | | | | | | | | | | | | | | Credits go to gdkchan and Ryujinx. The pull request used for this can be found here: https://github.com/Ryujinx/Ryujinx/pull/1082 yuzu was already using the header for interpolation, but it was missing the FragCoord.w multiplication described in the linked pull request. This commit finally removes the FragCoord.w == 1.0f hack from the shader decompiler. While we are at it, this commit renames some enumerations to match Nvidia's documentation (linked below) and fixes component declaration order in the shader program header (z and w were swapped). https://github.com/NVIDIA/open-gpu-doc/blob/master/Shader-Program-Header/Shader-Program-Header.html
