[PATCH v5] vhost: introduce mdev based hardware backend
...this could be used for future control vq where
it needs a kthread to access the userspace memory
- Temporarily filter? SET_LOG_BASE and SET_LOG_FD until we finalize the
API for dirty page tracking.
- For kick through kthread, it looks sub-optimal but we can address this
in the future, e.g call handle_vq_kick directly in vhost_poll_queue
(probably a flag for vhost_poll) and deal with the synchronization in
vhost_poll_flush carefully.
Thanks

[PATCH 0/2] tools/virtio: virtio_ring testing tool
This implements a virtio simulator:
- adds stubs for enough support functions to compile
virtio ring in userspace.
- Adds a stub vhost based module this can talk to.
This should help us decide things like which ring layout
works best.
Communication is currently done using an eventfd descriptor.
This means there's a shared spinlock there: what I would like to do
in the future, is run
