Remove auto lock from CreateTexture/Sampler API calls Add "no autolock" to Device::CreateTexture in dawn.json to prevent automatic locking at the API boundary. Introduce virtual method UseGuardForCreateTexture() that returns std::optional<DeviceGuard>. The default implementation returns a guard, but D3D11 overrides to return nullopt since its CreateTextureImpl is already thread-safe. Lock acquisition must happen at the API level, not within Impl methods, to avoid potential lock inversion issues when Impl methods are called by other internal functions. This CL also does similar things for Device::CreateSampler.

Dawn is an open-source and cross-platform implementation of the 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:
