This requires restructuring the logic around MTLCommandBuffer allocation so that GetPendingCommandContext is guaranteed to never fail. Logic in the Metal backend is now similar to the Vulkan backend: the MTLCommandBuffer is prepared at device initialization time, or after a submission, such that it is always valid. A new mUsed boolean is added to CommandRecordingContext to say whether any commands have been recording. Previously mCommandBuffer was used for that purpose, but it is now always non-null.

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
