From 47ff00881703eeab03d32e60289ac34b7f4a7994 Mon Sep 17 00:00:00 2001 From: Henrik Rydgard Date: Thu, 28 Apr 2016 19:01:47 +0200 Subject: [PATCH] Refactor: Extract VertexLoader from command_processor.cpp. Preparation for a similar concept to Dolphin or PPSSPP. These can be JIT-ed and cached. --- src/video_core/CMakeLists.txt | 2 + src/video_core/command_processor.cpp | 134 ++------------------------- src/video_core/shader/shader.h | 2 +- src/video_core/vertex_loader.cpp | 119 ++++++++++++++++++++++++ src/video_core/vertex_loader.h | 53 +++++++++++ 5 files changed, 185 insertions(+), 125 deletions(-) create mode 100644 src/video_core/vertex_loader.cpp create mode 100644 src/video_core/vertex_loader.h diff --git a/src/video_core/CMakeLists.txt b/src/video_core/CMakeLists.txt index 76cfd4f7de..de4082b1f1 100644 --- a/src/video_core/CMakeLists.txt +++ b/src/video_core/CMakeLists.txt @@ -16,6 +16,7 @@ set(SRCS shader/shader_interpreter.cpp swrasterizer.cpp utils.cpp + vertex_loader.cpp video_core.cpp ) @@ -43,6 +44,7 @@ set(HEADERS shader/shader_interpreter.h swrasterizer.h utils.h + vertex_loader.h video_core.h ) diff --git a/src/video_core/command_processor.cpp b/src/video_core/command_processor.cpp index 8030d17a77..8c3e982a39 100644 --- a/src/video_core/command_processor.cpp +++ b/src/video_core/command_processor.cpp @@ -22,6 +22,7 @@ #include "video_core/video_core.h" #include "video_core/debug_utils/debug_utils.h" #include "video_core/shader/shader_interpreter.h" +#include "video_core/vertex_loader.h" namespace Pica { @@ -192,62 +193,19 @@ static void WritePicaReg(u32 id, u32 value, u32 mask) { #if PICA_LOG_TEV DebugUtils::DumpTevStageConfig(regs.GetTevStages()); #endif - if (g_debug_context) g_debug_context->OnEvent(DebugContext::Event::IncomingPrimitiveBatch, nullptr); - const auto& attribute_config = regs.vertex_attributes; - const u32 base_address = attribute_config.GetPhysicalBaseAddress(); - int num_total_attributes = attribute_config.GetNumTotalAttributes(); - - // Information about internal vertex attributes - u32 vertex_attribute_sources[16]; - boost::fill(vertex_attribute_sources, 0xdeadbeef); - u32 vertex_attribute_strides[16] = {}; - Regs::VertexAttributeFormat vertex_attribute_formats[16] = {}; - - u32 vertex_attribute_elements[16] = {}; - u32 vertex_attribute_element_size[16] = {}; - bool vertex_attribute_default[16] = {}; - // Setup attribute data from loaders - for (int loader = 0; loader < 12; ++loader) { - const auto& loader_config = attribute_config.attribute_loaders[loader]; - - u32 offset = 0; - - // TODO: What happens if a loader overwrites a previous one's data?
