Add zoned device option to host_device BlockDriver. It will be presented only for zoned host block devices. By adding zone management operations to the host_block_device BlockDriver, users can use the new block layer APIs including Report Zone and four zone management operations (open, close, finish, reset, reset_all). Qemu-io uses the new APIs to perform zoned storage commands of the device: zone_report(zrp), zone_open(zo), zone_close(zc), zone_reset(zrs), zone_finish(zf). For example, to test zone_report, use following command: $ ./build/qemu-io --image-opts -n driver=host_device, filename=/dev/nullb0 -c "zrp offset nr_zones" Signed-off-by: Sam Li <faithilikerun@gmail.com> Reviewed-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Dmitry Fomichev <dmitry.fomichev@wdc.com> Acked-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-id: 20230508045533.175575-4-faithilikerun@gmail.com Message-id: 20230324090605.28361-4-faithilikerun@gmail.com [Adjust commit message prefix as suggested by Philippe Mathieu-Daudé <philmd@linaro.org> and remove spurious ret = -errno in raw_co_zone_mgmt(). --Stefan] Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> |
