The timestampWrites in render/compute pass descriptor store the timestamps at the beginning and end of passes, this requires validating all timestampWrite members in BeginXxxPass and inserting the timestampWrite cmd as close as possible to the BeginXxxPass and EndXxxPass. To do that, we first record only the querySets and queryIndexes that need to be used in BeginXxxPassCmd and EndXxxPassCmd, then insert timestampWrite cmd after the native BeginXxxPass and before the native EndXxxPass in backends. This CL adds timestampWrites in render/compute pass descriptor including the validation and tests first. Implement timestampWrites in backends in following CL.

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.h
version 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
