From 9764c13d6d2977903f407761b27d847c0056e1c4 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Wed, 30 Dec 2020 02:25:23 -0300 Subject: video_core: Rewrite the texture cache The current texture cache has several points that hurt maintainability and performance. It's easy to break unrelated parts of the cache when doing minor changes. The cache can easily forget valuable information about the cached textures by CPU writes or simply by its normal usage.The current texture cache has several points that hurt maintainability and performance. It's easy to break unrelated parts of the cache when doing minor changes. The cache can easily forget valuable information about the cached textures by CPU writes or simply by its normal usage. This commit aims to address those issues. --- .../renderer_vulkan/shaders/quad_indexed.comp | 50 ---------------------- 1 file changed, 50 deletions(-) delete mode 100644 src/video_core/renderer_vulkan/shaders/quad_indexed.comp (limited to 'src/video_core/renderer_vulkan/shaders/quad_indexed.comp') diff --git a/src/video_core/renderer_vulkan/shaders/quad_indexed.comp b/src/video_core/renderer_vulkan/shaders/quad_indexed.comp deleted file mode 100644 index 5a472ba9b..000000000 --- a/src/video_core/renderer_vulkan/shaders/quad_indexed.comp +++ /dev/null @@ -1,50 +0,0 @@ -// Copyright 2020 yuzu Emulator Project -// Licensed under GPLv2 or any later version -// Refer to the license.txt file included. - -/* - * Build instructions: - * $ glslangValidator -V quad_indexed.comp -o output.spv - * $ spirv-opt -O --strip-debug output.spv -o optimized.spv - * $ xxd -i optimized.spv - * - * Then copy that bytecode to the C++ file - */ - -#version 460 core - -layout (local_size_x = 1024) in; - -layout (std430, set = 0, binding = 0) readonly buffer InputBuffer { - uint input_indexes[]; -}; - -layout (std430, set = 0, binding = 1) writeonly buffer OutputBuffer { - uint output_indexes[]; -}; - -layout (push_constant) uniform PushConstants { - uint base_vertex; - int index_shift; // 0: uint8, 1: uint16, 2: uint32 -}; - -void main() { - int primitive = int(gl_GlobalInvocationID.x); - if (primitive * 6 >= output_indexes.length()) { - return; - } - - int index_size = 8 << index_shift; - int flipped_shift = 2 - index_shift; - int mask = (1 << flipped_shift) - 1; - - const int quad_swizzle[6] = int[](0, 1, 2, 0, 2, 3); - for (uint vertex = 0; vertex < 6; ++vertex) { - int offset = primitive * 4 + quad_swizzle[vertex]; - int int_offset = offset >> flipped_shift; - int bit_offset = (offset & mask) * index_size; - uint packed_input = input_indexes[int_offset]; - uint index = bitfieldExtract(packed_input, bit_offset, index_size); - output_indexes[primitive * 6 + vertex] = index + base_vertex; - } -} -- cgit v1.2.3
