Loko Kung 75c978f9b9 Fixes buffer unmapping issue in D3D12
- Ensures that the D3D12 buffer destruction implementation no longer handles unmapping as that is now handled in the frontend.
- Moves around when the frontend buffer state is set to MappedAtCreation so that it only happens when the staging buffer (when necessary) is created successfully. Note that if the staging buffer was not created successfully, we will never return that buffer and would instead return an error buffer anyways. We need the state to be Unmapped though since it needs to be properly destroyed.

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
