Currently Queue::SubmitImpl() may cause two queue submissions, one is because of Tick() call which will submit pending commands if there are. The other one is after converting frontend commands to backend command buffer. Queue::SubmitImpl() will submit converted commands. However usually queue submissions are expensive, so merge those two queue submissions into one by not calling Tick() before converting frontend commands, so pending commands and recorded commands can be submitted together. After that, we call Tick() to resolve callbacks and perform bookkeeping operations (deallocating memory for passed operations, etc).

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, 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.
