vhost-scsi: support VIRTIO_SCSI_F_HOTPLUG
So far there isn't way to test host kernel vhost-scsi event queue path, because VIRTIO_SCSI_F_HOTPLUG isn't supported by QEMU. virtio-scsi.c and vhost-user-scsi.c already support VIRTIO_SCSI_F_HOTPLUG as property "hotplug". Add support to vhost-scsi.c to help evaluate and test event queue. To test the feature: 1. Create vhost-scsi target with targetcli. targetcli /backstores/fileio create name=storage file_or_dev=disk01.raw targetcli /vhost create naa.1123451234512345 targetcli /vhost/naa.1123451234512345/tpg1/luns create /backstores/fileio/storage 2. Create QEMU instance with vhost-scsi. -device vhost-scsi-pci,wwpn=naa.1123451234512345,hotplug=true 3. Once guest bootup, hotplug a new LUN from host. targetcli /backstores/fileio create name=storage02 file_or_dev=disk02.raw targetcli /vhost/naa.1123451234512345/tpg1/luns create /backstores/fileio/storage02 Signed-off-by: Dongli Zhang <dongli.zhang@oracle.com> Message-Id: <20250203005215.1502-1-dongli.zhang@oracle.com> Acked-by: Stefano Garzarella <sgarzare@redhat.com>
