Bug 1575008 - WebGPU implementation basis r=webidl,baku
Browse files Browse the repository at this point in the history
This change vendors `wgpu` library in-tree and hooks up the initialization bits. It implements adapter and device initialization and adds a simple test.

Current status:
  - [x] Architecture
    - [x] figure out the IPC story
    - [ ] move wgpu crates into a dedicated folder (let's follow up with this)
  - [x] Review
    - [x] WebIDL changes by DOM peers
  - [x] Linux
    - [x] avoid depending on spirv_cross - gfx-rs/wgpu#371
  - [x] macOS
    - [x] due to cross-compiling shaders - gfx-rs/gfx#3047
    - [x] need the dependency update
    - [x] stop using gcc - SSheldon/rust-objc-exception#5
    - [x] unexpected SSL header collision - https://phabricator.services.mozilla.com/D51148
    - [x] undefined Metal symbols
    - [x] missing webrtc headers for IPDL magic - https://phabricator.services.mozilla.com/D51558
  - [x] Windows
    - [x] due to "ipc-channel" not supporting Windows yet - servo/ipc-channel#233
    - [x] due to some exceptional stuff - grovesNL/spirv_cross#121
    - [x] undefined symbol: `D3D12CreateDevice`
    - [x] d3d12.dll is not found, dxgi1_4 doesn't present
    - [x] d3d11.dll and dxgi.dll need to be explicitly loaded on win32 mingw - gfx-rs/gfx#3076
    - [x] libbacktrace fails to link on win32 mingw
    - [x] cc mislinking C++ standard library - rust-lang/cc-rs#455
  - [x] Android
    - [x] spirv-cross fails to build - KhronosGroup/SPIRV-Cross#1193

Update-1:
We decided to go with IPDL mechanism instead of Rust based ipc-channel (or any alternatives), which unblocks Windows build.

Update-2:
It appears that WebGPUThreading isn't needed any more as the child thread (and its event loop) is now managed by IPDL infrastructure. This PR removes it 🎉 .

Update-3:
InstanceProvider is also removed.

Update-4:
All set, the try is green, waiting for dependent changes to go in.
