This is a simple RefCounted holder of a Buffer ref and offset. Encoded commands can store a ref to this object instead of directly storing an inline Buffer ref and offset, allowing other commands to dynamically patch in a different buffer+offset as needed, in a memory-safe way; as opposed to e.g. retaining an unmanaged pointer to the encoded command itself and modifying it in-place. Validation commands will use this to rewrite buffer references in encoded commands, so that they execute over validated inputs rather than over their original client-provided inputs. No net functional changes in this CL, just some groundwork for indirect draw/dispatch validation.

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
