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
