I'm not sure exactly what you're asking here. Are you asking if the vfio_ap_mdev_open()+static int vfio_ap_mdev_open(struct mdev_device *mdev)Can't this happen while the guest is already running? Or what hinders us
+{
+ struct ap_matrix_mdev *matrix_mdev = mdev_get_drvdata(mdev);
+ unsigned long events;
+ int ret;
+
+ matrix_mdev->group_notifier.notifier_call = vfio_ap_mdev_group_notifier;
+ events = VFIO_GROUP_NOTIFY_SET_KVM;
+ ret = vfio_register_notifier(mdev_dev(mdev), VFIO_GROUP_NOTIFY,
+ &events, &matrix_mdev->group_notifier);
+
+ ret = kvm_ap_configure_matrix(matrix_mdev->kvm,
+ matrix_mdev->matrix);
+ if (ret)
+ return ret;
+
+ ret = kvm_ap_enable_ie_mode(matrix_mdev->kvm);
from doing that?
+Thanks,
+ return ret;
+}
