This is a reland of d08a14b70982a90423f4965ae5625847316de09e It gates dawn_use_swiftshader on dawn_enable_vulkan because the Vulkan backend isn't supported on Mac. We may support Swiftshader Vulkan on Mac in the future, but that will first require changes to how we initialize the Vulkan backend. Original change's description: > Use Swiftshader by default when fuzzing > > Note: This still requires Chromium to have set dawn_swiftshader_dir > to take effect. > > Bug: dawn:295 > Change-Id: I0c953196630dd2694f68d290e6f3f1e427c20a2f > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/14821 > Reviewed-by: Corentin Wallez <cwallez@chromium.org> > Reviewed-by: Kai Ninomiya <kainino@chromium.org> > Commit-Queue: Austin Eng <enga@chromium.org> Bug: dawn:295 Change-Id: Ia125005b35951021702104a99a78712bcd47dd1e Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/14941 Reviewed-by: Kai Ninomiya <kainino@chromium.org> Commit-Queue: 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
