Before I switched to AMD, I was passing an NVidia GPU (GTX 660) into my vir=
tual
machine, and I could unbind and rebind it between nouveau and vfio-pci as m=
uch
as I wanted. No trouble at all. Even while X was running, once DRI3 support
came. I switched to AMD expecting the same functionality. Thankfully, not
having said functionality isn't the end of the world, but having to reboot =
my
computer every time I want to play a game in Windows right after playing a =
game
in Linux is exactly the kind of pain that I spent a summer setting up the V=
M to
avoid.
