This patch fixes a crash issue in both D3D12 and Vulkan backends. Previously on D3D12 and Vulkan before a compute pass we transitioned the states of all the resources used in the pass, and before each dispatch call we only checked if the states of the storage buffers, read-only storage textures and write-only storage textures need to be transitioned. This behavior causes two issues: 1. In a compute pass a buffer or texture can be used as both read-only and writable usages in different dispatch calls (e.g. as storage buffer in the first dispatch, and as the uniform buffer in the next dispatch), while this is invalid state combination on D3D12 and isn't allowed by D3D12 validation layer. 2. In the above case, the state of the buffer is not transitioned into UNIFORM, which does not match the required state in the next dispatch. This patch fixes this issue by transitioning all the states in the current bind group before each dispatch() instead of the beginning of the compute pass.

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.hversion 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
