'virtio' type is supported right now. I plan to add 'vhost' type
on top which requires some virtual IOMMU implemented in this sample
driver.

Hi all:
There are hardwares that can do virtio datapath offloading while
having its own control path. This path tries to implement a mdev based
unified API to support using kernel virtio driver to drive those
devices. This is done by introducing a new

Do we still need the class ID? It's a virtio mdev bus,
do we need a virtio class as well?
If we want to have auto matc
eperate headers
- drop the mdev_set_dma_ops()
- use device_ops to implement the transport API, then it's not a part
of UAPI any more
- use GFP_ATOMIC in mvnet sample device and other tweaks
- set_vring_base/get_vring_base support for mvnet device
Jason Wang (6):
mdev: make mdev bus agn
mdev_vfio module
- require to specify the type of bus when registering mdev device and
mdev driver
With those modifications mdev become a generic module that could be
used by multiple types of virtual buses and devices.

Helpers for setting and getting the ops were introduced to support

This patch implements a mediated virtio bus over mdev framework. This
will be used by the future virtio-mdev and vhost-mdev on top to allow
driver from either userspace or kernel to control the device which is
capable of offloading virtio datapath.
