Check the how-to series on vfio.blogspot.com.  vfio-bind is just a hack
for binding all the device in a group to vfio-pci.  If you're using
libvirt, libvirt can do that binding for you.  There's still the
problem for GPUs though that we want to avoid the native driver
entirely.  This is often where the pci-stub.ids boot options come into
play.  The way that Roel is doing it is to bind directly to vfio-pci
early in the initramfs, solving two problems at once, the native driver
is avoided and the device is already bound to vfio-pci for assignment.
