[PATCH 00/18] vhost-vDPA multiqueue |
Date: |

Hi All:
This patch implements the multiqueue support for vhost-vDPA. The most
important requirement the control virtqueue support. The virtio-net
and vhost-net core are tweak to support control virtqueue as if what
data queue pairs are done: a dedicated vhost_net device which is
coupled with the NetClientState is intrdouced so most of the existing
vhost codes could be reused with minor changes. With the control
virtqueue, vhost-vDPA are extend to support creating and destroying
multiqueue queue pairs plus the control virtqueue.
Tests are done via the vp_vdpa driver in L1 guest.
Please reivew.
Thanks
