Enhance their handling in some aspects, specifically - accept common size suffixes (k, m) - perform consistency checks on the values - lift the upper limit on physical_block_size and logical_block_size Also fix the accessor for opt_io_size in virtio-blk to make it consistent with the size of the field. History: v7 -> v8: - replace stringify with %u in error messages [Eric] - fix wording in logs [Eric] v6 -> v7: - avoid overflow in min_io_size check [Eric] - try again to perform the art form in patch splitting [Eric] v5 -> v6: - fix forgotten xen-block and swim - add prop_size32 instead of going with 64bit v4 -> v5: - re-split the patches [Philippe] - fix/reword error messages [Philippe, Kevin] - do early return on failed consistency check [Philippe] - use QEMU_IS_ALIGNED instead of open coding [Philippe] - make all BlockConf size props support suffixes - expand the log for virtio-blk opt_io_size [Michael] v3 -> v4: - add patch to fix opt_io_size width in virtio-blk - add patch to perform consistency checks [Kevin] - check min_io_size against truncation [Kevin] v2 -> v3: - mention qcow2 cluster size limit in the log and comment [Eric] v1 -> v2: - cap the property at 2 MiB [Eric] - accept size suffixes Roman Kagan (8): virtio-blk: store opt_io_size with correct size block: consolidate blocksize properties consistency checks qdev-properties: blocksize: use same limits in code and description qdev-properties: add size32 property type qdev-properties: make blocksize accept size suffixes block: make BlockConf size props 32bit and accept size suffixes qdev-properties: add getter for size32 and blocksize block: lift blocksize property limit to 2 MiB include/hw/block/block.h | 14 +- include/hw/qdev-properties.h | 5 +- hw/block/block.c | 40 ++- hw/block/fdc.c | 5 +- hw/block/nvme.c | 5 +- hw/block/swim.c | 5 +- hw/block/virtio-blk.c | 9 +- hw/block/xen-block.c | 6 +- hw/core/qdev-properties.c | 85 +++++- hw/ide/qdev.c | 5 +- hw/scsi/scsi-disk.c | 12 +- hw/usb/dev-storage.c | 5 +- tests/qemu-iotests/172.out | 532 +++++++++++++++++------------------ 13 files changed, 419 insertions(+), 309 deletions(-)
