1. Auto-generate mutex locking code in DawnNative's ProcTable's functions. Using a mutex owned by the related Device. - Unless the function/class has "no autolock" attribute (new) in dawn.json. In which cases, no locking code will be auto-generated. - Currently Instance, Adapter, Surface, Encoder classes and Reference/Release method have "no autolock". 2. Added Feature::ImplicitDeviceSynchronization to enable Device's mutex. - If this feature is disabled, lock/unlock Device's mutex is no-op. Auto-generated locking code will have no effect. This is the default. - This approach is used instead of generating two sets of ProcTable because it's cleaner and the internal code doesn't need to care about whether there is a mutex being locked or not. Furthermore, if there were two sets of ProcTable, and user used dawnProcSetProcs() to set global ProcTable, it would affect all other modules using different Devices. Even though those modules don't need thread safety.

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, Metal, Vulkan and OpenGL. See per API support for more details.
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
- Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
