Austin Eng 2e48f011b0 Add an option for the Adapter to use tiered limits 
Does nothing right now since Dawn always exposes the default limits.
In the future, setting useTieredLimits to true will bucket the
exposed adapter limits to minimize fingerprinting surface.

Disabled by default for native applications, but Chrome will always
enable it.

Dawn's logo: a sun rising behind a stylized mountain inspired by the WebGPU logo. The text "Dawn" is written below 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.
  • 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
