-VFIO virtual device
-===================
-
-Device types supported:
-  KVM_DEV_TYPE_VFIO
-
-Only one VFIO instance may be created per VM.  The created device
-tracks VFIO groups in use by the VM and features of those groups
-important to the correctness and acceleration of the VM.  As groups
-are enabled and disabled for use by the VM, KVM should be updated
-about their presence.  When registered with KVM, a reference to the
-VFIO-group is held by KVM.
-
-Groups:
-  KVM_DEV_VFIO_GROUP
-
-KVM_DEV_VFIO_GROUP attributes:
-  KVM_DEV_VFIO_GROUP_ADD: Add a VFIO group to VFIO-KVM device tracking
-	kvm_device_attr.addr points to an int32_t file descriptor
-	for the VFIO group.
-  KVM_DEV_VFIO_GROUP_DEL: Remove a VFIO group from VFIO-KVM device tracking
-	kvm_device_attr.addr points to an int32_t file descriptor
-	for the VFIO group.
-  KVM_DEV_VFIO_GROUP_SET_SPAPR_TCE: attaches a guest visible TCE table
-	allocated by sPAPR KVM.
-	kvm_device_attr.addr points to a struct:
-
-	struct kvm_vfio_spapr_tce {
-		__s32	groupfd;
-		__s32	tablefd;
-	};
-
-	where
-	@groupfd is a file descriptor for a VFIO group;
-	@tablefd is a file descriptor for a TCE table allocated via
-		KVM_CREATE_SPAPR_TCE.
