From 2ccf85a9103afbb4dc227e481bb0e3a7360e833b Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Thu, 26 Nov 2020 16:49:20 -0300 Subject: [PATCH] vk_shader_decompiler: Implement force early fragment tests Force early fragment tests when the 3D method is enabled. The established pipeline cache takes care of recompiling if needed. This is implemented only on Vulkan to avoid invalidating the shader cache on OpenGL. --- src/video_core/engines/maxwell_3d.h | 7 ++++++- src/video_core/renderer_vulkan/fixed_pipeline_state.cpp | 7 ++++--- src/video_core/renderer_vulkan/fixed_pipeline_state.h | 8 ++++---- src/video_core/renderer_vulkan/vk_pipeline_cache.cpp | 1 + src/video_core/renderer_vulkan/vk_shader_decompiler.cpp | 6 +++--- src/video_core/renderer_vulkan/vk_shader_decompiler.h | 1 + 6 files changed, 19 insertions(+), 11 deletions(-) diff --git a/src/video_core/engines/maxwell_3d.h b/src/video_core/engines/maxwell_3d.h index 1cbe8fe67e..b0d9559d0c 100644 --- a/src/video_core/engines/maxwell_3d.h +++ b/src/video_core/engines/maxwell_3d.h @@ -755,7 +755,11 @@ public: u32 data_upload; - INSERT_UNION_PADDING_WORDS(0x44); + INSERT_UNION_PADDING_WORDS(0x16); + + u32 force_early_fragment_tests; + + INSERT_UNION_PADDING_WORDS(0x2D); struct { union { @@ -1572,6 +1576,7 @@ ASSERT_REG_POSITION(shadow_ram_control, 0x49); ASSERT_REG_POSITION(upload, 0x60); ASSERT_REG_POSITION(exec_upload, 0x6C); ASSERT_REG_POSITION(data_upload, 0x6D); +ASSERT_REG_POSITION(force_early_fragment_tests, 0x84); ASSERT_REG_POSITION(sync_info, 0xB2); ASSERT_REG_POSITION(tess_mode, 0xC8); ASSERT_REG_POSITION(tess_level_outer, 0xC9); diff --git a/src/video_core/renderer_vulkan/fixed_pipeline_state.cpp b/src/video_core/renderer_vulkan/fixed_pipeline_state.cpp index fffae528ea..5ec43db11a 100644 --- a/src/video_core/renderer_vulkan/fixed_pipeline_state.cpp +++ b/src/video_core/renderer_vulkan/fixed_pipeline_state.cpp @@ -46,7 +46,7 @@ void FixedPipelineState::Fill(const Maxwell& regs, bool has_extended_dynamic_sta regs.polygon_offset_fill_enable}; const u32 topology_index = static_cast(regs.draw.topology.Value()); - raw = 0; + raw1 = 0; primitive_restart_enable.Assign(regs.primitive_restart.enabled != 0 ?
