Previously the ObjectAllocator was tracking the generation on the side of the object. This was done to avoid the need to check that the objects aren't null before accessing the generation in ClientHandlers. This is only a very minor optimization for return commands so it is removed in favor of simplifying the code. The code is simplified in a bunch of place by getting the ObjectHandle for an object directly (since it knows the generation now) instead of walking the object graph returned by the allocator. The ObjectBase class is also changed to store an ObjectHandle interrnally that's only accessible via getters. Encapsulating the other memebers will be done in follow-up CLs. Also adds the generation to the ObjectBaseParams since all ObjectBases now require it.

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
- Tint is a compiler for the WebGPU Shader Language (WGSL).
