For virtio, it doesn't depends on that to work. Thanks

Hi all: During the development of virtio-mdev[1]. I find that mdev needs to be extended to support devices other than vfio mdev device. So this series tries to extend the mdev to be able to differ from different devices by: - device id and matching for mdev bus - device speicfic callbacks and move vfio callbacks there Sent for early reivew, compile test only! Thanks [1]

Hi all: There are hardware 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 mdev transport for virtio (virtio_mdev) and register itself as a new kind of mdev driver. Then it provides a unified way for kernel virtio driver to
