I’m picking up an RX480 soon to pair with my GTX970 to do this. Was going to get a 5700, but I can do that later. Just want an 8 GB card.
Am I going to see issues in-system like say if I were to just boot linux normally? Like, before I configured the cards? I’m going to use Pop_OS (I don’t want to deal with Void and Nvidia again) so that my GTX970 is just ready to go, but I don’t want my 480 to get in the way.
to your /etc/modprobe.d/blacklist.conf if you don’t want your host to use the RX480 at all. Then you can add its PCI ID to /etc/modprobe.d/vfio.conf and use it with the VM(assuming you’ve set up everything properly).
I also have a 5700XT (uses the same kernel module as the RX480) and it works well with passthrough if I blacklist amdgpu(using it with both the host and VM is a different story). You should be fine if you don’t want to use it with the host at all.
