Status: RESOLVED FIXED

(Core :: Graphics: WebGPU, enhancement)

Description

[Sotaro Ikeda [:sotaro]]

In chromium uses ID3D11Fence and ID3D12Fence for fence handling The fence handling seems necessary also in gecko.

D3DSharedFence is used for D3D11

d3d12::Fence is used for D3D12.

The following functions control begin/end access from D3D11/D3D12.
D3DImageBacking::BeginAccessD3D11()
D3DImageBacking::EndAccessD3D11()
D3DImageBacking::BeginAccessDawn()
D3DImageBacking::EndAccessDawn()

Change to wgpu might be necessary to do the followings.

• wgpu-core
  • A way to get last_submit_index for Texture of texture_id
  • A way to get wgpu::Device.fence
• wgpu-hal
  • A way to get d3d12::Fence from wgpu_hal::dx12::Texture
  • A way to create d3d12::Fence with d3d12_ty::D3D12_FENCE_FLAG_SHARED for wgpu::Device<api::Dx12>.fence
