I try GPU passthrough in qubes. I have laptop with 2 GPUs. I need use GPU passthrough for my rx550.
I use this: Contents/windows-gaming-hvm.md at master · Qubes-Community/Contents · GitHub Another 2. GPU passthrough post

I detached GPU from dom0 and send it to appVM, but driver not work. I has this in appVM:

$ lspci -nnk

	Subsystem: Acer Incorporated [ALI] Lexa [Radeon 540X/550X/630 / RX 640 / E9171 MCM] [1025:152b]
	Kernel modules: amdgpu

I haven’t kernel driver in use.

I send this devices to my appVM and I block their for dom0 in /etc/default/grub
