Jiawei Shao 3b17f0bde8 Optimize B2T and T2B copies with multiple texture layers on D3D12
This patch optimizes the implementation of buffer-to-texture and
texture-to-buffer computations on D3D12 backends by computing
TextureCopySplits once for all the 2D texture array layers in the
copy instead of computing it once per layer. You can see the
comments in the function D3D12::ComputeTextureCopySplits() for more
details.

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
