Li Hao 92182412b8 Implement timestampWrites on Metal
Metal configures the query set and query index for the beginning and end
of passes in pass descriptor when beginning a pass encoder, so we need
to record all timestamp writes information in BeginXxxPassCmd. For the
platfroms that support timestamp query, it must support timestamp write
at command boundary or stage boundary, if the stage boundary is
supported, use sampleBufferAttachments API for Metal implementation,
otherwise simulate timestamp write using sampleCountersInBuffer API
after begining a pass and before ending a pass.

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.
  • A "native" implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • 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) that can be used in standalone to convert shaders from and to WGSL.
