[RFC PATCH 0/2] virtio-mmio: add irqfd support for vhost-net based on virtio-mmio
From: Li Liu <john.liuli at huawei.com>
This set of patches try to implemet irqfd support of vhost-net
based on virtio-mmio.
I had posted a mail to talking about the status of vhost-net
on kvm-arm refer to http://www.spinics.net/lists/kvm-arm/msg10804.html.
Some dependent patches are listed in the mail too. Basically the
vhost-net brings great performance improvements, almost 50%+.
