[Intel-gfx] [RFC PATCH 0/2] Mdev: support mutiple kinds of devices

[Jason Wang]

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
