Currently, the bind group layout tightly packs the shader registers for each of the sampler and non-sampler descriptors sets. This reduces the max shader register used and helps targeting shader model 5.0, which has a relatively low max slot count per resource. It is safe in D3D, since a shader register collision can be valid if the descriptor types differ. To support Mesa's SPIR-V to DXIL compiler, we need to avoid possible collisions between resources' shader registers because it uses SPIR-V as an intermediate representation (which does not namespace bindings by type). This change re-works BindGroupLayoutD3D12 to not assume the resulting shader registers will be tightly packed and group per descriptor type.

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
.
- 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
