This patch adds a regression test to dawn_end2end_tests for an Intel D3D12 driver bug about the T2T copies with specific texture formats when the source mipmap level is greater than 0. This patch also does several clean-ups in CopyTests.cpp to support testing arbitrary texture formats: 1. Initialize the source textures with device.WriteTexture(). 2. Set default values for TextureSpec.copyLevel (0), TextureSpec.levelCount (1) and TextureSpec.copyOrigin ({0, 0, 0}). 3. Add TextureSpec.format and set the default value for it (RGBA8Unorm). 4. Support initializing and comparing the texture data with arbitrary texture format instead of RGBA8Unorm only in CopyTests_T2T. 5. Check all the texels in the related destination texture subresources instead of only the copied texels.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h
that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.h
version that Dawn implements. - A C++ wrapper for the
webgpu.h
.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs:
- D3D12 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
