2016-08-24 Thread Kirti Wankhede
This series adds Mediated device support to Linux host kernel. Purpose of this series is to provide a common interface for mediated device management that can be used by different devices. This series introduces Mdev core module that create and manage mediated devices, VFIO based driver for
