BlockConf includes several properties counted in bytes.
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

The width of opt_io_size in virtio_blk_config is 32bit. However, it's
written with virtio_stw_p; this may result in value truncation, and on
big-endian systems with legacy virtio in completely bogus readings in
the guest.
Use the appropriate accessor to store it.

Several block device properties related to blocksize configuration must
be in certain relationship WRT each other: physical block must be no
smaller than logical block; min_io_size, opt_io_size, and
discard_granularity must be a multiple of a logical block.
To ensure these requirements are met, add corresponding consistency
checks to blkconf_blocksizes, adjusting its signature to communicate
possible error to the caller. Also remove the now redundant consistency
checks from the specific devices.

Make it easier (more visible) to maintain the limits on the blocksize
properties in sync with the respective description, by using macros both
in the code and in the description.

Introduce size32 property type which handles size suffixes (k, m, g)
just like size property, but is uint32_t rather than uint64_t. It's
going to be useful for properties that are byte sizes but are inherently
32bit, like BlkConf.opt_io_size or .discard_granularity (they are
switched to this new property type in a followup commit).
The getter for size32 is left out for a separate patch as its benefit is
less obvious, and it affects test output; for now the regular uint32
getter is used.

It appears convenient to be able to specify physical_block_size and
logical_block_size using common size suffixes.
Teach the blocksize property setter to interpret them. Also express the
upper and lower limits in the respective units.

Convert all size-related properties in BlockConf to 32bit. This will
accommodate bigger block sizes (in a followup patch). This also allows
to make them all accept size suffixes, either via DEFINE_PROP_BLOCKSIZE
or via DEFINE_PROP_SIZE32.
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.

Add getter for size32, and use it for blocksize, too.
In its human-readable branch, it reports approximate size in
human-readable units next to the exact byte value, like the getter for
64bit size does.
Adjust the expected test output accordingly.

* [PATCH v8 7/8] qdev-properties: add getter for size32 and blocksize

Add getter for size32, and use it for blocksize, too.
In its human-readable branch, it reports approximate size in
human-readable units next to the exact byte value, like the getter for
64bit size does.
Adjust the expected test output accordingly.

Logical and physical block sizes in QEMU are limited to 32 KiB.
This appears unnecessarily tight, and we've seen bigger block sizes
handy at times.
Lift the limitation up to 2 MiB which appears to be good enough for
everybody, and matches the qcow2 cluster size limit.

Pardon me if this has been answered already for prior revisions: do we
really support physical block sizes that are not a multiple of the
logical block size?

This no longer exercises floppy_drive_realize()'s check of
logical_block_size:
if (dev->conf.logical_block_size != 512 ||
dev->conf.physical_block_size != 512)
{
error_setg(errp, "Physical and logical block size must "
"be 512 for floppy");
return;
}
Please update the test.

Both physical and logical block sizes are required to be powers of two,
so the former is certain to be a multiple of the latter.

Right, this check of logical_block_size here becomes redundant now,
because eariler it's verified to be no less than 512 and no more than
physical_block_size, which is required to be 512 here. I thought it
made no harm to leave it here as it was, and decided not to bother
replacing it with a comment as to why the condition is known to be true.

The test still makes sense, it just triggers another assertion now. How
do you suggest to update it?

I guess we could just add another case with physical=logical=4096 so we
test both the original floppy check (with the new case) and your new
check (with the existing case).
But as you explained above, it's kind of redundant and we can't tell
from the result whether the logical or the physical check failed (they
are then both unsuitable for floppy), so maybe adding that case is
rather pointless.
