The standard virtio-mmio devices use notification register to signal
backend. This will cause vmexits and slow down the performance when we
passthrough the virtio-mmio devices to guest virtual machines.
We proposed to update virtio over MMIO spec to add the per-queue
notify feature VIRTIO_F_MMIO_NOTIFICATION[1]. It can allow the VMM to
configure notify location for each queue.

Hmm. Any way to make this static so we don't need
base and multiplier?
E.g page per vq?
Thanks
