This patch does several clean-ups in CopyTests as a preparation of supporting buffer-to-texture and texture-to-buffer copies with multiple texture array layers. 1. Remove the zero-initialization of textures in CopyTests_B2T 2. Use a big buffer that contains the pixel data in all the texture array layers instead of several small ones that only contains one texture array layer. 3. Make CopyTests_T2T::DoTest() also use CopyTests::TextureSpec as its input parameter. 4. Add tests for the copies with multiple texture array layers. In this patch we just copy the data once per texture array layer, while in the next patch we will be able to copy the data for all the related texture array layers in one copy command. 5. Move some helper functions for copy tests to WGPUHelpers.cpp BUG=dawn:453 TEST=dawn_end2end_tests Change-Id: Ia0150a6c55fffce3e24dda2cd45fd920b0873dc9 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/23120 Commit-Queue: Corentin Wallez <cwallez@chromium.org> Reviewed-by: Austin Eng <enga@chromium.org>
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.hversion 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
