  "message": "Vulkan: Fix VVL layout mismatch and YCbCr sampler filter errors\n\nFixes Vulkan validation layer errors during draw operations caused by\nimage layout and sampler creation mismatches (VUID-00344, VUID-01645):\n\n1. TextureView::VulkanImageLayout used the view\u0027s usage instead of the\n   underlying texture\u0027s usage, writing SHADER_READ_ONLY_OPTIMAL to\n   descriptor sets while command buffer barriers transitioned the image\n   to VK_IMAGE_LAYOUT_GENERAL (for textures with StorageBinding).\n2. Sampler creation and static sampler specialization for YCbCr external\n   formats allowed user-specified minFilter/magFilter, violating the\n   requirement that they must match chromaFilter.\n\nResolved by querying the underlying texture usage in TextureView\u0027s\nVulkanImageLayout and clamping minFilter and magFilter to chromaFilter\nwhen external formats or VK_FORMAT_UNDEFINED are used.\n\nAdds regression tests:\n- TextureViewTest.SampledTextureWithStorageBinding: verifies sampling a\n  TextureBinding view when the parent texture has StorageBinding usage.\n- SharedTextureMemoryYCbCrAndroidTests.SampleExternalTextureWithLinearSampler:\n  verifies sampling an external YCbCr AHB using a linear sampler.\n\nBug: b/546851865\nChange-Id: I9d1cf8a654800b112374cd27ce01e6a9d14d6f3b\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/340235\nReviewed-by: Brandon Jones \u003cbajones@chromium.org\u003e\nReviewed-by: Corentin Wallez \u003ccwallez@chromium.org\u003e\nCommit-Queue: Sanjeevi Suresh \u003csanjeevisuresh@google.com\u003e\n",
