From 5b2b6d594c6cfa77c3fb92faee63ad524bfe7204 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Thu, 4 Jun 2020 23:03:49 -0300 Subject: [PATCH] shader/texture: Join separate image and sampler pairs offline Games using D3D idioms can join images and samplers when a shader executes, instead of baking them into a combined sampler image. This is also possible on Vulkan. One approach to this solution would be to use separate samplers on Vulkan and leave this unimplemented on OpenGL, but we can't do this because there's no consistent way of determining which constant buffer holds a sampler and which one an image. We could in theory find the first bit and if it's in the TIC area, it's an image; but this falls apart when an image or sampler handle use an index of zero. The used approach is to track for a LOP.OR operation (this is done at an IR level, not at an ISA level), track again the constant buffers used as source and store this pair. Then, outside of shader execution, join the sample and image pair with a bitwise or operation. This approach won't work on games that truly use separate samplers in a meaningful way. For example, pooling textures in a 2D array and determining at runtime what sampler to use. This invalidates OpenGL's disk shader cache :) - Used mostly by D3D ports to Switch --- .../engines/const_buffer_engine_interface.h | 1 + src/video_core/engines/kepler_compute.cpp | 5 +- src/video_core/engines/kepler_compute.h | 2 + src/video_core/engines/maxwell_3d.cpp | 5 +- src/video_core/engines/maxwell_3d.h | 2 + .../renderer_opengl/gl_rasterizer.cpp | 18 ++++- .../renderer_opengl/gl_shader_disk_cache.cpp | 64 ++++++++++++---- .../renderer_opengl/gl_shader_disk_cache.h | 1 + .../renderer_vulkan/vk_rasterizer.cpp | 11 +++ src/video_core/shader/decode/texture.cpp | 55 +++++++++----- src/video_core/shader/node.h | 75 ++++++++----------- src/video_core/shader/node_helper.h | 2 +- src/video_core/shader/registry.cpp | 20 +++++ src/video_core/shader/registry.h | 35 +++++++++ src/video_core/shader/shader_ir.h | 4 +- src/video_core/shader/track.cpp | 24 ++++-- 16 files changed, 235 insertions(+), 89 deletions(-) diff --git a/src/video_core/engines/const_buffer_engine_interface.h b/src/video_core/engines/const_buffer_engine_interface.h index ebe139504..f46e81bb7 100644 --- a/src/video_core/engines/const_buffer_engine_interface.h +++ b/src/video_core/engines/const_buffer_engine_interface.h @@ -93,6 +93,7 @@ public: virtual SamplerDescriptor AccessBoundSampler(ShaderType stage, u64 offset) const = 0;
