From c574ab5aa1d3ff81b28ddfbba3818b3ce724aa32 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Sat, 4 Jul 2020 18:42:10 -0300 Subject: video_core/textures: Add and use SwizzleSliceToVoxel, and minor style changes Change GOB sizes from free-functions to constexpr constants. Add SwizzleSliceToVoxel, a function that swizzles a 2D array of pixels into a 3D texture and use it for 3D copies. --- src/video_core/textures/decoders.cpp | 134 ++++++++++++++++++++--------------- src/video_core/textures/decoders.h | 38 +++++++--- 2 files changed, 105 insertions(+), 67 deletions(-) (limited to 'src/video_core/textures') diff --git a/src/video_core/textures/decoders.cpp b/src/video_core/textures/decoders.cpp index 548e4c3fe..98beabef1 100644 --- a/src/video_core/textures/decoders.cpp +++ b/src/video_core/textures/decoders.cpp @@ -6,6 +6,7 @@ #include #include "common/alignment.h" #include "common/assert.h" +#include "common/bit_util.h" #include "video_core/gpu.h" #include "video_core/textures/decoders.h" #include "video_core/textures/texture.h" @@ -37,20 +38,10 @@ struct alignas(64) SwizzleTable { std::array, N> values{};
