Yang Gu 6a9f9bd1ff Skip the check of maxFragmentCombinedOutputResources for Mesa llvmpipe driver
The Mesa Gallium llvmpipe driver is a software rasterizer that uses LLVM
to do runtime code generation. It seems to put incorrect value for
maxFragmentCombinedOutputResources, like we see on desktop GPUs.

Some relative values are as below.
vkLimits.maxFragmentCombinedOutputResources: 8
kMaxColorAttachments: 8
baseLimits.v1.maxStorageTexturesPerShaderStage: 4
baseLimits.v1.maxStorageBuffersPerShaderStage: 8

This CL will skip the check of this limit on llvmpipe, like we did for
desktop GPUs.

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 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
