• Add the included trybots in the CL description. All of these trybots are tested by the roll, but the final CQ-submit wouldn't necessarily test all of the variants before landing. This would mean that the 'cts export' could miss some results, as it takes the last PS with any results. • Add --force flag to cts roll to force a roll. Useful for testing. • Emit timing diagnostics for tests labelled 'Slow' instead of unhelpfully stating they pass. • Enable the --cl and --ps flags for cts export • Export with the most recent data to the top of the spreadsheet Bug: dawn:1401 Change-Id: Id926367ab805bfb9f3032fce9cce7f00daf7a5d4 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/88661 Reviewed-by: Dan Sinclair <dsinclair@chromium.org> Commit-Queue: Ben Clayton <bclayton@google.com> Kokoro: Kokoro <noreply+kokoro@google.com>
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
- Tint is a compiler for the WebGPU Shader Language (WGSL).
