Unable to load swapchain #9

I'm trying to run the example with cargo run -- xr and am getting this error:

I have since installed the LunarG Vulkan SDK, installed the latest drivers for my GPU (Nvidia GeForce GTX 1060) and SteamVR is running before I run cargo run -- xr. Are there any other setup steps I'm forgetting?

philpax commented 2 years ago

Hmm, do you have more than one GPU (i.e. integrated graphics) in your machine, and does cargo run -- desktop work? That looks like it's failing to create the swapchain for the window on the device that's being used for XR rendering; I'm not sure what could lead to that, other than a) disagreements over which device is responsible for rendering to that device or b) some kind of runtime Vulkan issue.

If it works in desktop mode, we can narrow it down to the device; if it doesn't, then there's something else askew with your Vulkan setup, and we'll have to keep debugging.

schell commented 2 years ago

It works in desktop mode!

Could it be that SteamVR (which is providing the OpenXR runtime) is using D3D and can't interop with Vulkan?

schell commented 2 years ago

In the SteamVR web console I do see it setting up D3D11 textures:

After enabling logging I can see that there is an available extension in wgpu_hal for this - maybe it has to be explicitly enabled? Forgive me if it's already being enabled and I just can't see it.

Hm, that might be the key! Try enabling it by adding it to the array here: https://github.com/philpax/wgpu-openxr-example/blob/main/src/xr.rs#L98

I'm guessing that the Vulkan device created for me includes the swapchain extension as a required extension, but yours doesn't. If that's the issue, then requesting it explicitly should fix it.

I've added it to #10 and now I'm seeing:

Error: XR error creating Vulkan instance

Caused by:
    the runtime failed to handle the function in an unexpected way that is not covered by another error result
schell commented 2 years ago

I downloaded a release of the openxr sdk here, which includes the "helloxr" app. I ran it with .\hello_xr.exe --graphics Vulkan and .\hello_xr.exe --graphics Vulkan2 and it connected to SteamVR and ran with no errors, so I don't think it's the device or the vulkan driver situation. Maybe there are some other steps we're missing when using my hardware/software setup that are implicit in your setup (like the vulkan extension).

I've added a few more logs to #10 but still haven't been able to figure it out. OpenXR is erring with XR_ERROR_RUNTIME_FAILURE, which seems to be an error code for "some other unenumerated error".

Hmm... this is so strange. Are you sure it's running on the correct device? What does your system configuration look like?

I'm not sure how to find out if it's selecting the correct device, I just assumed that OpenXR and SteamVR would work that out! Please let me know if there are some steps or info I'm missing. I'm new to developing on Windows, so I'm not confident in what is relevant.

Sorry, I've had a busy week! I don't see anything immediately strange there, but my current running theory is that Direct Mode (as used by your headset) produces a different Vulkan device as to what's used to render your desktop / windows.

Can you try disabling the swapchain extension and removing all of the windowing logic (you should be able to replace the winit loop with a loop)? If that works, then we'll need to think about how to properly decouple the window and XR rendering.

That might even clean up the initialisation logic - there can now be an unconditional creation of the WGPU state with winit - but device-to-device copies might be a bit of a headache. If you can confirm the no-window approach works, I'll see if I can sketch something out for decoupling it.
