This is used to sync the physical tray state after migration when
using CD-ROM passthrough. However, migrating when using passthrough
is broken anyway and shouldn't be supported...
So, drop this function as it causes a problem with the DEVICE_TRAY_MOVED
event, which is going to be introduced by the next commit.

It's not needed. Besides we can then assume that bdrv_eject() is
only called when there's a tray state change, which is useful to
the DEVICE_TRAY_MOVED event (going to be added in a future

They are QMP events, not monitor events. Rename them accordingly.
Also, move bdrv_emit_qmp_error_event() up in the file. A new event will
be added soon and it's good to have them next each other.

Replace device_init() with generalized type_init().
While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace.

bdrv_aio_cancel() can trigger bdrv_aio_flush() which makes all aio
that is currently in flight finish. So what we do is:
port reset
detect ncq in flight
cancel ncq
delete ncq sg list
at which point we have double freed the sg list. Instead, with this
patch we do:
port reset
detect ncq in flight
cancel ncq
check if we are really still in flight
delete ncq sg list
which makes things work and gets rid of the race.

Limit them to the device_add functionality. Device aliases were a hack based
on the fact that virtio was modeled the wrong way. The mechanism for aliasing
is very limited in that only one alias can exist for any device.
We have to support it for the purposes of compatibility but we only need to
support it in device_add so restrict it to that piece of code.

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.
The first step was a sed-based addition of the parent type to the subclass
registration functions.
The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.
Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.
We are almost fully converted to QOM after this commit.

These are various small stylistic changes which help make things more
consistent such that the automated conversion script can be simpler.
It's not necessary to agree or disagree with these style changes because all
of this code is going to be rewritten by the patch monkey script anyway.

Back when I made patches introducing dma_addr_t and various PCI DMA
wrapper functions, I made a mistake. The bmdma_addr_{read,write} functions
need to take target_phys_addr_t not dma_addr_t, since they are assigned
to MemoryRegionOps callbacks.
This patch corrects my error.

Many places in QEMU call qemu_aio_flush() to complete all pending
asynchronous I/O. Most of these places actually want to drain all block
requests but there is no block layer API to do so.
This patch introduces the bdrv_drain_all() API to wait for requests
across all BlockDriverStates to complete. As a bonus we perform checks
after qemu_aio_wait() to ensure that requests really have finished.

Mode page 2A of emulated ATAPI DVD-ROM should have page length 0x14
like SCSI CD-ROM, rather than 0x12.
Mode page length is off by 8, as it should contain the length of the
payload after the first two bytes.
MODE SENSE(6) should be thrown out of ATAPI DVD-ROM emulation. It is
not specified in the ATAPI list of MMC-2, and MMC-5 prescribes to use
MODE SENSE(10). Anyway, its implementation is wrong.

A few offsets were wrong in atapi.c. Also change the 2Ah mode page to
expose DVD media read capabilities in the IDE cdrom. This lets you run

The definitions in ide/internal.h are duplicates, since ATAPI commands
actually come from SCSI. Use the ones in scsi-defs.h and move the
missing ones there. Two exceptions:
- MODE_PAGE_WRITE_PARMS conflicts with the "flexible disk geometry"
page in scsi-disk.c. It is unused, so pick the latter.
- GPCMD_* is left in ide/internal.h, at least for now.
