example wgpu03 panics on linux #1

Open ToddG opened 1 year ago

ToddG commented 1 year ago

On my linux machine, example wgpu02 lists my adapters an opens a blank window as expected. Here are the adapters it lists:

/home/todd/temp/wgpu-examples/wgpu02/target/debug/wgpu02
AdapterInfo { name: "AMD Unknown (RADV RENOIR)", vendor: 4098, device: 5686, device_type: IntegratedGpu, backend: Vulkan }
AdapterInfo { name: "llvmpipe (LLVM 15.0.6, 256 bits)", vendor: 65541, device: 0, device_type: Cpu, backend: Vulkan }
AdapterInfo { name: "RENOIR (renoir, LLVM 15.0.6, DRM 3.47, 5.19.0-42-generic)", vendor: 4098, device: 0, device_type: Other, backend: Gl }

However, example wgpu03 panics with:

"Failed to find an appropriate adapter"

here in the .request_adapter() call:

pub async fn run(event_loop: EventLoop<()>, window: Window) {      
    let size = window.inner_size();
    let instance = wgpu::Instance::new(wgpu::Backends::DX12);
    let surface = unsafe { instance.create_surface(&window) };
    let adapter = instance
        .request_adapter(&wgpu::RequestAdapterOptions {
            power_preference: wgpu::PowerPreference::default(),
            compatible_surface: Some(&surface),
            force_fallback_adapter: false,
        })
        .await
        .expect("Failed to find an appropriate adapter");

Clearly I have a GPU see specs here. What do I need to do to get the wgpu03 example working?

My Windows 11 machine has backends DX12 and Vulkan, and I found that DX12 works better. So I used DX12 backend to create the instance:

let instance = wgpu::Instance::new(wgpu::Backends::DX12);

In your Linux machine, you may use Vulkan backend instead:

let instance = wgpu::Instance::new(wgpu::Backends::VULKAN);

or just use all() as backend:

let instance = wgpu::Instance::new(wgpu::Backends::all());

don't know if this fixes your problem.
