+|Reference VFIO Stub driver used for discrete assignment of IO, and assignment of some SR-IOV-backed vGPU devices into virtual machines. This driver is commonly replaced with a vendor built VFIO interface with differing memory management and/or page pinning mechanisms which are specific to the vGPU software internals.
