We could: (1) have the same order in the QAPI definition as the the BLK_PERM_* flags are in LSb-first order. However, then there is no guarantee that they actually match (e.g. when someone modifies the QAPI schema without thinking of the BLK_PERM_* definitions). We could add static assertions, but these would break what’s good about this solution, namely its simplicity. (2) define the BLK_PERM_* flags based on the BlockPermission values. But this way whenever someone were to modify the QAPI order (perfectly sensible in theory), the BLK_PERM_* values would change. Because these values are used for file locking, this might break file locking between different qemu versions. Therefore, go the slightly more cumbersome way: Add a function to translate from the QAPI constants to the BLK_PERM_* flags.

This patch adds this capability to blkdebug. (Note that you cannot make blkdebug release or share permissions that it needs to take or cannot share, because this might result in assertion failures in the block layer. But if the blkdebug node has no parents, it will not take any permissions and share everything by default, so you can then freely choose what permissions to take and share.)

Whatever options the test needs should simply be appended. Some tests do this (with IMGOPTS=$(_optstr_add "$IMGOPTS" "...")), but that is cumbersome. It’s simpler to just give _make_test_img an -o parameter with which tests can add options. Some tests actually must override the user-specified options, though, for example when creating an image in a different format than the test $IMGFMT. For such cases, --no-opts allows clearing the current option list.

Accomplish this by passing options to _make_test_img via -o instead of $IMGOPTS. For some tests, there is no functional change because they already only appended options to IMGOPTS. For these, this patch is just a simplification. For others, this is a change, so they now heed user-specified $IMGOPTS.

Furthermore, we should not print qcow2.py's list of incompatible features because it differs depending on whether there is an external data file or not.

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> --- meson.build | 5 + include/block/block-io.h | 9 + include/block/block_int-common.h | 21 ++ include/block/raw-aio.h | 6 +- include/sysemu/block-backend-io.h | 18 ++ block/block-backend.c | 137 +++++++++++++ block/file-posix.c | 313 +++++++++++++++++++++++++++++- block/io.c | 41 ++++ qemu-io-cmds.c | 149 ++++++++++++++ 9 files changed, 696 insertions(+), 3 deletions(-) diff --git a/meson.build b/meson.build index XXXXXXX..XXXXXXX 100644 --- a/meson.build +++ b/meson.build @@ -XXX,XX +XXX,XX @@ if rdma.found() endif # has_header_symbol +config_host_data.set('CONFIG_BLKZONED', + cc.has_header_symbol('linux/blkzoned.h', 'BLKOPENZONE')) config_host_data.set('CONFIG_EPOLL_CREATE1', cc.has_header_symbol('sys/epoll.h', 'epoll_create1')) config_host_data.set('CONFIG_FALLOCATE_PUNCH_HOLE', @@ -XXX,XX +XXX,XX @@ config_host_data.set('HAVE_SIGEV_NOTIFY_THREAD_ID', config_host_data.set('HAVE_STRUCT_STAT_ST_ATIM', cc.has_member('struct stat', 'st_atim', prefix: '#include <sys/stat.h>')) +config_host_data.set('HAVE_BLK_ZONE_REP_CAPACITY', + cc.has_member('struct blk_zone', 'capacity', + prefix: '#include <linux/blkzoned.h>')) # has_type config_host_data.set('CONFIG_IOVEC', diff --git a/include/block/block-io.h b/include/block/block-io.h index XXXXXXX..XXXXXXX 100644 --- a/include/block/block-io.h +++ b/include/block/block-io.h @@ -XXX,XX +XXX,XX @@ int coroutine_fn GRAPH_RDLOCK bdrv_co_flush(BlockDriverState *bs);

More details about ZBDs can be found at: + +https://zonedstorage.io/docs/introduction/zoned-storage + +1. Block layer APIs for zoned storage +------------------------------------- +QEMU block layer supports three zoned storage models: +- BLK_Z_HM: The host-managed zoned model only allows sequential writes access +to zones. It supports ZBD-specific I/O commands that can be used by a host to +manage the zones of a device. +- BLK_Z_HA: The host-aware zoned model allows random write operations in +zones, making it backward compatible with regular block devices. +- BLK_Z_NONE: The non-zoned model has no zones support. It includes both +regular and drive-managed ZBD devices. ZBD-specific I/O commands are not +supported. + +The block device information resides inside BlockDriverState. QEMU uses +BlockLimits struct(BlockDriverState::bl) that is continuously accessed by the +block layer while processing I/O requests. A BlockBackend has a root pointer to +a BlockDriverState graph(for example, raw format on top of file-posix). The +zoned storage information can be propagated from the leaf BlockDriverState all +the way up to the BlockBackend. If the zoned storage model in file-posix is +set to BLK_Z_HM, then block drivers will declare support for zoned host device. + +The block layer APIs support commands needed for zoned storage devices, +including report zones, four zone operations, and zone append. + +2. Emulating zoned storage controllers +-------------------------------------- +When the BlockBackend's BlockLimits model reports a zoned storage device, users +like the virtio-blk emulation or the qemu-io-cmds.c utility can use block layer +APIs for zoned storage emulation or testing. + +For example, to test zone_report on a null_blk device using qemu-io is:: + + $ path/to/qemu-io --image-opts -n driver=host_device,filename=/dev/nullb0 -c "zrp offset nr_zones" diff --git a/docs/system/qemu-block-drivers.rst.inc b/docs/system/qemu-block-drivers.rst.inc index XXXXXXX..XXXXXXX 100644 --- a/docs/system/qemu-block-drivers.rst.inc +++ b/docs/system/qemu-block-drivers.rst.inc @@ -XXX,XX +XXX,XX @@ Hard disks you may corrupt your host data (use the ``-snapshot`` command line option or modify the device permissions accordingly). +Zoned block devices + Zoned block devices can be passed through to the guest if the emulated storage + controller supports zoned storage.

To do this, the file-posix driver tracks the wp location of all zones of the device. It uses an array of uint64_t. The most significant bit of each wp location indicates if the zone type is conventional zones. The zones wp can be changed due to the following operations issued: - zone reset: change the wp to the start offset of that zone - zone finish: change to the end location of that zone - write to a zone - zone append Signed-off-by: Sam Li <faithilikerun@gmail.com> Message-id: 20230508051510.177850-2-faithilikerun@gmail.com [Fix errno propagation from handle_aiocb_zone_mgmt() --Stefan] Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> --- include/block/block-common.h | 14 +++ include/block/block_int-common.h | 5 + block/file-posix.c | 178 ++++++++++++++++++++++++++++++- 3 files changed, 193 insertions(+), 4 deletions(-) diff --git a/include/block/block-common.h b/include/block/block-common.h index XXXXXXX..XXXXXXX 100644 --- a/include/block/block-common.h +++ b/include/block/block-common.h @@ -XXX,XX +XXX,XX @@ typedef struct BlockZoneDescriptor { BlockZoneState state; } BlockZoneDescriptor; +/* + * Track write pointers of a zone in bytes. + */ +typedef struct BlockZoneWps { + CoMutex colock; + uint64_t wp[]; +} BlockZoneWps; + typedef struct BlockDriverInfo { /* in bytes, 0 if irrelevant */ int cluster_size; @@ -XXX,XX +XXX,XX @@ typedef enum { #define BDRV_SECTOR_BITS 9 #define BDRV_SECTOR_SIZE (1ULL << BDRV_SECTOR_BITS) +/* + * Get the first most significant bit of wp.

When writing to a zoned block device using zone append, the byte offset of the call may point at any position within the zone to which the data is being appended. Upon completion the device will respond with the position where the data has been written in the zone.

It supports Report Zone, four zone oparations (open, close, finish, reset), and Append Zone. The VIRTIO_BLK_F_ZONED feature bit will only be set if the host does support zoned block devices. Regular block devices(conventional zones) will not be set. The guest os can use blktests, fio to test those commands on zoned devices.
