This introduces a new field 'doYuvToRgbConversionOnly' in ExternalTextureParams to have the WGSL only do yuv->rgb conversion for better performance. User studies shows that users don't really care about the Gamma difference between 2.4 and 2.2. https://source.chromium.org/chromium/chromium/src/+/main:ui/gfx/color_space.cc;l=1022;drc=a1dbb594a6741a400db35fe3678e77bad2504ea4 Bug: dawn:1082 Bug: dawn:1466 Change-Id: I61c0fe65c5969d8a61c267c202c8dd64c259ed8a Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/92901 Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Jie A Chen <jie.a.chen@intel.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).
