Crash in gbm_dri_bo_import on ASPEED + AMDGPU system

[Dana Goyette]

I have a server machine with an ASPEED BMC (kernel driver `ast`) and a Radeon Pro WX 4100 (driver `amdgpu`). If I try to log into a KDE Wayland session or a Gnome Wayland session, it crashes back to the login screen, with the same innermost level in the traceback.

What I'd like to be able to do: if a monitor is connected to the AMD GPU, then show the login screen on that, and maybe duplicate it on the BMC. If no external monitor is connected, show it only on the BMC. Ideally, it should switch on the fly, but at the very least, it shouldn't crash.

Note that in Xorg sessions, it doesn't crash, but xrandr only shows outputs from the AMD GPU. If I do xrandr --listproviders, I see that the `ast` has no capabilities.

Provider 0: id: 0x58 cap: 0x9, Source Output, Sink Offload crtcs: 5 outputs: 4 associated providers: 0 name:AMD Radeon (TM) Pro WX 4100 @ pci:0000:0e:00.0
Provider 1: id: 0x99 cap: 0x0 crtcs: 1 outputs: 1 associated providers: 0 name:modesetting

It really would be nice to support using it as a dumb output like DisplayLink, even if it has to allow tearing or drop many frames.

Dana, Ubuntu 21.10 is no longer supported, can you try with a newer Ubuntu if the problem is still reproducible?
