Bug Description
Description:
VFIO (Virtual Function I/O) is an IOMMU/device agnostic framework for exposing direct device access to user space in a secure IOMMU protected environment. VFIO/MDEV(mediated device) is based on VFIO to provide a generic framework for mediated devices simulated by a real physical device. Current vfio/mdev doesn’t implement full iommu support. With scalable mode supported by IOMMU hardware, each mediated device could be isolated and protected by IOMMU. Hence all IOMMU ops could be handled in vfio/mdev (no dependency on the parent device).
