Is there a plan to add an API in vDPA_config_ops for getting the notification area from the VDPA device (something similar to get_notify_area in the VDPA DPDK case)? This will make the notifications from the guest (vhost_vdpa use case) to the VDPA device more efficient - at least for virtio 1.0+ drivers in the VM. I believe this would require enhancement to the vhost ioctl (something similar to the VHOST_USER_SLAVE_VRING_HOST_NOTIFIER_MSG). Regards, Harpreet
