Le Hoang Quyen 7971bfe16f Add an option to enable implicit device synchronization.
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.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • 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.
