This patch refactors the implementation of APICreateComputePipelineAsync as a preparation of the async path of the creation of compute pipeline. Now the code path of APICreateComputePipelineAsync() includes the following 3 parts: - When an error occurs in the front-end validations, the callback will be called at once in the main thread. - When we can find a proper compute pipeline object in the cache, the callback will be called at once in the main thread. - When we cannot find the proper comptue pipeline object in the cache, the newly-created pipeline object, the callback and userdata will be saved into the CreatePipelineAsyncTracker, and the callback will be called in device.Tick(). All the logic mentioned in this section has been put into one function CreateComputePipelineAsyncImpl(), which will be overrided by its asynchronous version on all the backends that support creating pipeline objects asynchronously. Note that APICreateRenderPipelineAsync is not changed in this patch because it is now under refactoring to match the current updates in WebGPU SPEC.

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
