Commit 0d936928ef87ca1bb7b41b5b89c400c699a7691c removed code,
but left the related comment at a location where it no longer
belongs to.
The patch moves the comment to the correct callback and improves the text.

Since commit 541dc0d47f10973c241e9955afc2aefc96adec51,
some new packed structures were added without using QEMU_PACKED.
QEMU_PACKED is needed for compilations with MinGW.
For other platforms nothing changes.
The code was fixed using this command:
git grep -la '__attribute__ ((packed))'|xargs perl -pi -e 's/__attribute__ \(\(packed\)\)/QEMU_PACKED/'

By default mingw-gcc is trying to pack structures the way to
preserve binary compatibility with MS Visual C what leads to
incorrect and unexpected padding in the PCI bus ranges property of
the sPAPR PHB.
The patch replaces __attribute__((packed)) with more strict QEMU_PACKED
which actually is __attribute__((gcc_struct, packed)) on Windows.

qdev_prop_set_string uses object_property_set_str, which takes
a const char * for the value. Lets propagate the constness

All current users (IDE, SCSI and virtio-blk) happen to share this 20
characters limit. Still, it should be left to device models. They
already enforce their limits. They have to, as the DriveInfo limit
only affects legacy -drive serial=..., not the qdev properties.
usb-storage, which doesn't limit serial number length, also uses
DriveInfo for -usbdevice. But that doesn't provide access to
DriveInfo serial.

New limits straight from ATA4 6.2 Register delivered data transfer

I figure the old sector limit 63 was blindly copied from the BIOS
int 13 limit. Doesn't apply to the hardware. No idea where the old

Currently, it is split between hd_geometry_guess() and

There are two producers of these hints: drive_init() on behalf of
-drive, and hd_geometry_guess().
The only consumer of the hint is hd_geometry_guess().
The callers of hd_geometry_guess() call it only when drive_init()
didn't set the hints. Therefore, drive_init()'s hints are never used.
Thus, hd_geometry_guess() only ever sees hints it produced itself in a
prior call. Only the first call computes something, subsequent calls
just repeat the first call's results. However, hd_geometry_guess() is
never called more than once: the device models don't, and the block
device is destroyed on unplug. Thus, dropping the repeat feature
doesn't break anything now.
If a block device wasn't destroyed on unplug and could be reused with
a new device, then repeating old results would be wrong. Thus,
dropping the repeat feature prevents future breakage.
This renders the hints unused. Purge them from the block layer.

This isn't quite orthodox. CHS translation is firmware configuration,
communicated via the RTC's CMOS RAM, not a property of the disk. But
it's best to treat it just like geometry anyway.
Maintain backward compatibility exactly like for geometry: fall back
to DriveInfo's translation, set with -drive trans=...
Bonus: info qtree now shows the translation. Except when it shows
"auto": that's resolved by pc_cmos_init_late(). To be addressed
shortly.

hd_geometry_guess() picks geometry and translation. Callers can get
the geometry directly, via parameters, but for translation they need
to go through the block layer.
Add a parameter for translation, so it can optionally be gotten just
like geometry. In preparation of purging translation from the block
layer, which will happen later in this series.

When hd_geometry_guess() picks a geometry, it also picks the
appropriate translation, but only when the prior translation hint is
BIOS_ATA_TRANSLATION_AUTO. Looks wrong, because such a prior
translation would be passed to the BIOS whether it's suitable for the
geometry or not.
Fortunately, that can't happen. There are just two ways for the
translation hint to get set to something other than
BIOS_ATA_TRANSLATION_AUTO: drive_init() on behalf of -drive trans=...,
and hd_geometry_guess(). Both set it only when they also set a valid
geometry hint, i.e. one with a non-zero number of cylinders.
Since hd_geometry_guess() returns right away when it finds a valid
geometry hint, translation can only be BIOS_ATA_TRANSLATION_AUTO in
the remainder of the function.
Assert this, and simplify accordingly.

Commit f3d54fc4 factored it out of hw/ide.c for reuse. Sensible,
except it was put into block.c. Device-specific functionality should
be kept in device code, not the block layer. Move it to

checkpatch.pl happy.

Commit 5bbdbb46 moved it to block.c because "other geometry guessing
functions already reside in block.c". Device-specific functionality
should be kept in device code, not the block layer. Move it back.
Disk geometry guessing is still in block.c. To be moved out in a
later patch series.
Bonus: the floppy type used in pc_cmos_init() now obviously matches
the one in the FDrive. Before, we relied on
bdrv_get_floppy_geometry_hint() picking the same type both in
fd_revalidate() and in pc_cmos_init().

With the async schedule being kicked from other places than the frame
timer (commit 0f588df8b3688b00e77aabaa32e26ece5f19bd39) it may happen
that we call ehci_commit_interrupt() more than once per frame.
Move the call from the async schedule handler to the frame timer to
restore old irq behavior, which is more correct. Fixes regressions
with some linux kernel versions.
