Support event idx feature for virtio-blk device. This feature could improve disk IO performance by suppressing notifications from guest to host and interrupts from host to guest, which has been already supported in virtio-net and vhost-user devices. To achieve this, virtqueue's event-idx-related API is leveraged for avail_event field update and needs_notification check. Fixes: #6580 Signed-off-by: wuxinyue <wuxinyue.wxy@antgroup.com> |
