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]
