[PATCH 0/3] Extend vhost to support VFIO based accelerator

[Tiwei Bie <tiwei.bie@intel.com>]

This patch set introduces the VFIO based accelerator support
for vhost. This is a new vhost user protocol feature to better
support the vDPA device at the vhost user backend. It allows
interrupts/notifications being delivered between the driver
in guest and the device in host directly.

Dependencies:

1. This patch set depends on the below patch set for QEMU:

http://lists.nongnu.org/archive/html/qemu-devel/2018-01/msg06028.html

Some of the enum definitions in this patch set have been
updated for the latest QEMU. A new patch set for QEMU will
be sent out later.

2. This patch set depends on Zhihong's "selective datapath"
   patch set:

http://dpdk.org/ml/archives/dev/2018-March/091858.html

This patch set is generated on the latest master branch of
dpdk-next-virtio with Zhihong's patches applied.

Best regards,
Tiwei Bie
