[Qemu-devel] [PATCH 0/4] ioeventfd support for virtio-mmio

[Shannon Zhao]

Add host/guest notifiers support for virtio-mmio, so that qemu can
enable vhost-net for kvm-arm.

Refer to the patches from Ying-Shiuan Pan
https://lists.gnu.org/archive/html/qemu-devel/2014-02/msg00715.html

As vhost-net can improve the net performance by about 30%,
so I think it's necessary to make virtio-mmio work with vhost-net
on arm/arm64.

Shannon Zhao (4):
  virtio-mmio: introduce set_host_notifier()
  virtio-mmio: introduce set_guest_notifiers
  virtio-mmio: start ioeventfd when status gets DRIVER_OK
  virtio-mmio: add a new property for ioeventfd
