Using this container is a small performance regression in the simple cases where all subresources are the same, or when the texture has few subrsources. However it give better performance in the hard subresource tracking cases of textures with many subresources. Using SubresourceStorage also makes it easier to work with compressed storage since the compression is mostly transparent. It reduces code duplication and prevent bugs from appearing when a developer would forget to handle compression. This fixes a state tracking issue in ValidatePassResourceUsage where the function didn't correctly handle the case where the PassResourceUsage was compressed. Also removes the unused vulkan::Texture::TransitionFullUsage. Also makes SubresourceStorage<T> only require operator== on T and not operator !=. Also fixes the texture format's aspect being used to create pipeline barriers instead of the range's aspects.

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
.
- 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
