To start I am now running Arch with the VFIO kernel, I did not compile
with the i915, my machine failed to boot with that last time. Currently
I can't seem to get VFIO to claim the devices I want to pass-through.
You can see kernel driver is still nvidia. I added my configs below. I
even tried a script. Every time I modify mkinitcpio.conf I regenerate
my intramfd with mkinitcpio -p linux-vfio
What am I missing?
