From 8bba84a4014e1bf204089ff7dbcaa73917f84738 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Sun, 24 May 2020 17:57:54 -0300 Subject: [PATCH 1/3] texture_cache: Implement depth stencil texture swizzles Stop ignoring image swizzles on depth and stencil images. This doesn't fix a known issue on Xenoblade Chronicles 2 where an OpenGL texture changes swizzles twice before being used. A proper fix would be having a small texture view cache for this like we do on Vulkan. --- .../renderer_opengl/gl_texture_cache.cpp | 39 +++++++++++++------ .../renderer_opengl/gl_texture_cache.h | 10 +---- .../renderer_vulkan/vk_texture_cache.cpp | 29 +++++++------- 3 files changed, 42 insertions(+), 36 deletions(-) diff --git a/src/video_core/renderer_opengl/gl_texture_cache.cpp b/src/video_core/renderer_opengl/gl_texture_cache.cpp index 94fbd2a22..7e0ffe3cd 100644 --- a/src/video_core/renderer_opengl/gl_texture_cache.cpp +++ b/src/video_core/renderer_opengl/gl_texture_cache.cpp @@ -238,6 +238,12 @@ OGLTexture CreateTexture(const SurfaceParams& params, GLenum target, GLenum inte return texture; } +constexpr u32 EncodeSwizzle(SwizzleSource x_source, SwizzleSource y_source, SwizzleSource z_source, + SwizzleSource w_source) { + return (static_cast(x_source) << 24) | (static_cast(y_source) << 16) | + (static_cast(z_source) << 8) | static_cast(w_source); +} + } // Anonymous namespace CachedSurface::CachedSurface(const GPUVAddr gpu_addr, const SurfaceParams& params, @@ -404,7 +410,8 @@ CachedSurfaceView::CachedSurfaceView(CachedSurface& surface, const ViewParams& p if (!is_proxy) { texture_view = CreateTextureView(); } - swizzle = EncodeSwizzle(SwizzleSource::R, SwizzleSource::G, SwizzleSource::B, SwizzleSource::A); + current_swizzle = + EncodeSwizzle(SwizzleSource::R, SwizzleSource::G, SwizzleSource::B, SwizzleSource::A); } CachedSurfaceView::~CachedSurfaceView() = default; @@ -449,25 +456,35 @@ void CachedSurfaceView::Attach(GLenum attachment, GLenum target) const { void CachedSurfaceView::ApplySwizzle(SwizzleSource x_source, SwizzleSource y_source, SwizzleSource z_source, SwizzleSource w_source) { - u32 new_swizzle = EncodeSwizzle(x_source, y_source, z_source, w_source); - if (new_swizzle == swizzle) + const u32 new_swizzle = EncodeSwizzle(x_source, y_source, z_source, w_source); + if (current_swizzle == new_swizzle) { return; - swizzle = new_swizzle; - const std::array gl_swizzle = {GetSwizzleSource(x_source), GetSwizzleSource(y_source), - GetSwizzleSource(z_source), GetSwizzleSource(w_source)}; + } + current_swizzle = new_swizzle; + + std::array swizzle{x_source, y_source, z_source, w_source}; + const GLuint handle = GetTexture(); - const PixelFormat format = surface.GetSurfaceParams().pixel_format; - switch (format) { + switch (const PixelFormat format = surface.GetSurfaceParams().pixel_format) { + case PixelFormat::S8Z24: case PixelFormat::Z24S8: case PixelFormat::Z32FS8: - case PixelFormat::S8Z24: + UNIMPLEMENTED_IF(x_source != SwizzleSource::R && x_source != SwizzleSource::G); glTextureParameteri(handle, GL_DEPTH_STENCIL_TEXTURE_MODE, GetComponent(format, x_source == SwizzleSource::R)); - break; - default: + + // Make sure we sample the first component + std::transform(swizzle.begin(), swizzle.end(), swizzle.begin(), [](SwizzleSource value) { + return value == SwizzleSource::G ?
