From ddd82ef42b7bb7bea4c80edeb96bca8512580df3 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Fri, 24 Apr 2020 01:44:14 -0300 Subject: shader/memory_util: Deduplicate code Deduplicate code shared between vk_pipeline_cache and gl_shader_cache as well as shader decoder code. While we are at it, fix a bug in gl_shader_cache where compute shaders had an start offset of a stage shader. --- src/video_core/renderer_opengl/gl_shader_cache.cpp | 82 +++------------------- 1 file changed, 10 insertions(+), 72 deletions(-) (limited to 'src/video_core/renderer_opengl/gl_shader_cache.cpp') diff --git a/src/video_core/renderer_opengl/gl_shader_cache.cpp b/src/video_core/renderer_opengl/gl_shader_cache.cpp index f63156b8d..9759a7078 100644 --- a/src/video_core/renderer_opengl/gl_shader_cache.cpp +++ b/src/video_core/renderer_opengl/gl_shader_cache.cpp @@ -10,8 +10,6 @@ #include #include -#include - #include "common/alignment.h" #include "common/assert.h" #include "common/logging/log.h" @@ -28,76 +26,26 @@ #include "video_core/renderer_opengl/gl_shader_disk_cache.h" #include "video_core/renderer_opengl/gl_state_tracker.h" #include "video_core/renderer_opengl/utils.h" +#include "video_core/shader/memory_util.h" #include "video_core/shader/registry.h" #include "video_core/shader/shader_ir.h" namespace OpenGL { using Tegra::Engines::ShaderType; +using VideoCommon::Shader::GetShaderAddress; +using VideoCommon::Shader::GetShaderCode; +using VideoCommon::Shader::GetUniqueIdentifier; +using VideoCommon::Shader::KERNEL_MAIN_OFFSET; using VideoCommon::Shader::ProgramCode; using VideoCommon::Shader::Registry; using VideoCommon::Shader::ShaderIR; +using VideoCommon::Shader::STAGE_MAIN_OFFSET; namespace { -constexpr u32 STAGE_MAIN_OFFSET = 10; -constexpr u32 KERNEL_MAIN_OFFSET = 0; - constexpr VideoCommon::Shader::CompilerSettings COMPILER_SETTINGS{}; -/// Gets the address for the specified shader stage program -GPUVAddr GetShaderAddress(Core::System& system, Maxwell::ShaderProgram program) { - const auto& gpu{system.GPU().Maxwell3D()}; - const auto& shader_config{gpu.regs.shader_config[static_cast(program)]}; - return gpu.regs.code_address.CodeAddress() + shader_config.offset; -} - -/// Gets if the current instruction offset is a scheduler instruction -constexpr bool IsSchedInstruction(std::size_t offset, std::size_t main_offset) { - // Sched instructions appear once every 4 instructions. - constexpr std::size_t SchedPeriod = 4; - const std::size_t absolute_offset = offset - main_offset; - return (absolute_offset % SchedPeriod) == 0; -} - -/// Calculates the size of a program stream -std::size_t CalculateProgramSize(const ProgramCode& program) { - constexpr std::size_t start_offset = 10; - // This is the encoded version of BRA that jumps to itself.
