From 228f516bb4426a41a4d1c1756751557f7a0eecda Mon Sep 17 00:00:00 2001 From: Fernando Sahmkow Date: Fri, 24 May 2019 15:34:31 -0400 Subject: texture_cache uncompress-compress is untopological. This makes conflicts between non compress and compress textures to be auto recycled. It also limits the amount of mipmaps a texture can have if it goes above it's limit. --- src/video_core/texture_cache/surface_base.h | 18 +++++++++++++++-- src/video_core/texture_cache/surface_params.cpp | 4 ++++ src/video_core/texture_cache/surface_params.h | 14 +++++++++++++ src/video_core/texture_cache/texture_cache.h | 26 +++++++++++++------------ 4 files changed, 48 insertions(+), 14 deletions(-) (limited to 'src/video_core/texture_cache') diff --git a/src/video_core/texture_cache/surface_base.h b/src/video_core/texture_cache/surface_base.h index 77c2d6758..70b5258c9 100644 --- a/src/video_core/texture_cache/surface_base.h +++ b/src/video_core/texture_cache/surface_base.h @@ -32,6 +32,12 @@ enum class MatchStructureResult : u32 { None = 2, }; +enum class MatchTopologyResult : u32 { + FullMatch = 0, + CompressUnmatch = 1, + None = 2, +}; + class StagingCache { public: StagingCache() {} @@ -136,12 +142,20 @@ public: params.target == SurfaceTarget::Texture2D && params.num_levels == 1; } - bool MatchesTopology(const SurfaceParams& rhs) const { + MatchTopologyResult MatchesTopology(const SurfaceParams& rhs) const { const u32 src_bpp{params.GetBytesPerPixel()}; const u32 dst_bpp{rhs.GetBytesPerPixel()}; const bool ib1 = params.IsBuffer(); const bool ib2 = rhs.IsBuffer(); - return std::tie(src_bpp, params.is_tiled, ib1) == std::tie(dst_bpp, rhs.is_tiled, ib2); + if (std::tie(src_bpp, params.is_tiled, ib1) == std::tie(dst_bpp, rhs.is_tiled, ib2)) { + const bool cb1 = params.IsCompressed(); + const bool cb2 = rhs.IsCompressed(); + if (cb1 == cb2) { + return MatchTopologyResult::FullMatch; + } + return MatchTopologyResult::CompressUnmatch; + } + return MatchTopologyResult::None; } MatchStructureResult MatchesStructure(const SurfaceParams& rhs) const { diff --git a/src/video_core/texture_cache/surface_params.cpp b/src/video_core/texture_cache/surface_params.cpp index d9d157d02..77c09264a 100644 --- a/src/video_core/texture_cache/surface_params.cpp +++ b/src/video_core/texture_cache/surface_params.cpp @@ -85,6 +85,7 @@ SurfaceParams SurfaceParams::CreateForTexture(Core::System& system, } params.pitch = params.is_tiled ?
