Mdev is a way to virtualize devices\nin Linux kernel. Based on the device-api (mdev_type/device_api),\nthere could be different types of mdev devices (e.g. vfio-pci).\nIn this RFCv2, the PCI bus driver is extended to support scanning\nand probing the mdev devices whose device-api is \"vfio-pci\".\n\n +---------+\n | PCI bus |\n +----+----+\n |\n +--------+-------+-------+--------+\n | | | |\n Physical PCI devices ...
