Ken Rockot 44d729fc8c Introduce BufferLocation
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.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • 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
