Original change's description:
> [dawn][wire] Handle command chunking in the wire in more robustly.
>
> - With the changes to make the wire more spontaneous, chunked
>   command serialization and handling need to be updated to work
>   in a multithreaded manner. Previously, the handler assumes that
>   once a chunked command is received, it will receive the entire
>   chunked command before it receives any other commands. This may
>   no longer be true, so we upgrade chunked commands into its own
>   command so with unique id's to ensure that we handle them
>   appropriately.
> - This change also unifies the command id enums in the wire to a
>   single enum since chunked command handling may occur on both
>   the server and the client (though in practice in Chromium,
>   only the server->client may be multithreaded for now.) This
>   allows us to handle commands in a unified way and also ensures
>   that the command ids are now unique both direction.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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.
