[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v6 4/5] block: make size-related BlockConf properties accept size suffixes
Several BlockConf properties represent respective sizes in bytes so it
makes sense to accept size suffixes for them.
Turn them all into uint32_t and use size-suffix-capable setters/getters
on them; introduce DEFINE_PROP_SIZE32 and adjust DEFINE_PROP_BLOCKSIZE
for that. (Making them uint64_t and reusing DEFINE_PROP_SIZE isn't
justified because guests expect at most 32bit values.)
Also, since min_io_size is exposed to the guest by scsi and virtio-blk
devices as an uint16_t in units of logical blocks, introduce an
additional check in blkconf_blocksizes to prevent its silent truncation.
Signed-off-by: Roman Kagan <rvkagan@xxxxxxxxxxxxxx>
---
v5 -> v6:
- add prop_size32 instead of going with 64bit
v4 -> v5:
- make all BlockConf size props support suffixes
- move qdev_prop_blocksize after qdev_prop_size, to reuse get_size
- reword error messages [Kevin]
