This reverts commit 9fdbb74072a084e3085aaaba18276c53fa3463de. Reason for revert: The SPIRV-Cross GN files have a bug which is fixed upstream, but Skia is on an old version of SPIRV-Cross so they don't have the fix. So, the build fails when rolling Dawn into Skia complaining about unknown `-fno-exceptions` on the windows bots. Need Skia to either move to vulkan-deps, or roll their spirv-cross forward before this can re-land. Original change's description: > Use upstream SPIRV-Cross GN files. > > Previously spirv-cross didn't have its own sources files but this > changed recently so we should use them. This will ultimately allow > sharing targets between multiple components in Chromium. > > Bug: chromium:1179277 > Change-Id: Ib4bb1884b9ba9c4c3804e96d8adbb8905c60c9a3 > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/41725 > Auto-Submit: Corentin Wallez <cwallez@chromium.org> > Reviewed-by: Peng Huang <penghuang@chromium.org> > Reviewed-by: Austin Eng <enga@chromium.org> > Commit-Queue: Corentin Wallez <cwallez@chromium.org> Bug: chromium:1179277 Change-Id: If1003bafa7b35f502c08b2dab91dd3d416aab077 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/42420 Commit-Queue: dan sinclair <dsinclair@chromium.org> Commit-Queue: Austin Eng <enga@chromium.org> Auto-Submit: dan sinclair <dsinclair@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
