wgpu & WSL2

[geefuoco]

I am interested in learning graphics programming in rust through wgpu. My current workstation is on WSL2.

Environment: wsl2 Ubuntu 20.04
wgpu = 0.16
winit = 0.28

I am having trouble trying to open a window on WSL. When printing the adapters, I can see that I have my GPU available

AdapterInfo { name: "llvmpipe (LLVM 12.0.0, 256 bits)", vendor: 65541, device: 0, device_type: Cpu, driver: "llvmpipe", driver_info: "Mesa 21.2.6 (LLVM 12.0.0)", backend: Vulkan }
AdapterInfo { name: "D3D12 (NVIDIA GeForce GTX 1080)", vendor: 0, device: 0, device_type: Other, driver: "", driver_info: "", backend: Gl }

Although it produces the error
ERROR wgpu::backend::direct] Error in Adapter::request_device: Limit 'max_compute_workgroups_per_dimension' value 65535 is better than allowed 0

I have gone through the steps of installing cuda on WSL2 here hoping that would fix it, but it did not.

Here is a snapshot of nvidia-smi on my wsl instance

If I build the binary targeted to windows, I can run the .exe file and it runs as expected (so far). However, for development, if I use cargo run, I am getting this error. Is there any way to fix this ?

I have found a work around at the moment. By create a .cargo/config.toml file in the project directory, you can set the default compile target

[build]
target = "x86_64-pc-windows-gnu"

That way, it will compile to windows, and will run properly, allowing for quick iterations in development
