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. --- src/video_core/rasterizer_interface.h | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'src/video_core/rasterizer_interface.h') diff --git a/src/video_core/rasterizer_interface.h b/src/video_core/rasterizer_interface.h index 27ef4c69a..0cb0f387d 100644 --- a/src/video_core/rasterizer_interface.h +++ b/src/video_core/rasterizer_interface.h @@ -76,6 +76,9 @@ public: /// Sync memory between guest and host. virtual void SyncGuestHost() = 0; + /// Unmap memory range + virtual void UnmapMemory(VAddr addr, u64 size) = 0; + /// Notify rasterizer that any caches of the specified region should be flushed to Switch memory /// and invalidated virtual void FlushAndInvalidateRegion(VAddr addr, u64 size) = 0; @@ -83,6 +86,12 @@ public: /// Notify the host renderer to wait for previous primitive and compute operations. virtual void WaitForIdle() = 0; + /// Notify the host renderer to wait for reads and writes to render targets and flush caches. + virtual void FragmentBarrier() = 0; + + /// Notify the host renderer to make available previous render target writes. + virtual void TiledCacheBarrier() = 0; + /// Notify the rasterizer to send all written commands to the host GPU. virtual void FlushCommands() = 0; @@ -91,8 +100,7 @@ public: /// Attempt to use a faster method to perform a surface copy [[nodiscard]] virtual bool AccelerateSurfaceCopy( - const Tegra::Engines::Fermi2D::Regs::Surface& src, - const Tegra::Engines::Fermi2D::Regs::Surface& dst, + const Tegra::Engines::Fermi2D::Surface& src, const Tegra::Engines::Fermi2D::Surface& dst, const Tegra::Engines::Fermi2D::Config& copy_config) { return false; } -- cgit v1.2.3
