d3d12: Use fixed key for keyed mutex acquire and release Chromium has switched to using a fixed key (0) for quite some time. Using a fixed key enables future work needed for concurrent access of external textures both inside Dawn (e.g. importing a video frame twice) or across Dawn and GL. We want to try scoping the Acquire/Release calls to command list submission, but with a non-fixed key concurrent access for the same resource becomes ambiguous.

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:
