a Server-Grade Software-Only ARM Hypervisor), the vhost-net increased at least
30% in throughput comparing to virtio-net.
Ying-Shiuan Pan (4):
virtio-mmio: introduce set_host_notifier()
virtio-mmio: introduce set_guest_notifiers
virtio-mmio: start ioeventfd when status gets DRIVER_OK
to 'bool ioeventfd' of VirtIODevice.
Any better suggestion?

set_host_notifier() is introduced into virtio-mmio now. Most of codes came
from virtio-pci.

Same as host notifier of virtio-mmio, most of codes came from virtio-pci.
The kvm-arm does not yet support irqfd, need to fix the hard-coded part after
kvm-arm gets irqfd support.

vhost-net could be truned on by changing the last parameter vhost=on.

and the throughput of vhost-net on that platform (with 1Gbps Ethernet)
increased from 323Mbps to 435Mbps.

virtio-mmio: fix features negotiation problem
virtio-mmio should invoke virtio_set_features() when it gets
VIRTIO_MMIO_GUESTFEATURES command, since some devices (at least, virtio-net)
register their own set_features method and setup their features in that.
