Restart of ATAPI DMA used to be unreachable, because the request to do
so wasn't indicated in bus->error_status due to the lack of spare bits, and
ide_restart_bh() would return early doing nothing.
This patch makes use of the observation that not all bit combinations were
possible in ->error_status. In particular, IDE_RETRY_READ only made sense
together with IDE_RETRY_DMA or IDE_RETRY_PIO. This allows to re-use
IDE_RETRY_READ alone as an indicator of ATAPI DMA restart request.
To makes things more uniform, ATAPI DMA gets its own value for ->dma_cmd.
As a means against confusion, macros are added to test the state of
->error_status.
The patch fixes the restart of both in-flight and pending ATAPI DMA,
following the scheme similar to that of IDE DMA.

ide_atapi_dma_restart() used to just complete the DMA with an error,

However, as the contents of the ->io_buffer is preserved, it looks safe to

This has two significant drawbacks. First the main loop hangs util an

complete (e.g. due to an unresponsive storage) Qemu hangs completely.
Note: Due to possible race conditions requests during an ongoing

(With the previous atapi_dma flag recovery)
If migration happens between the ATAPI command being written and the
bmdma being started, the DMA is dropped. Eventually the guest times
out and recovers, but that can take many seconds.
(This is rare, on a pingpong reading the CD continuously I hit
this about ~1/30-1/50 migrates)
I don't think we've got enough state to be able to recover safely
at this point, so I throw a 'medium error, no seek complete'
that I'm assuming guests will try and recover from an apparently
dirty CD.
OK, it's a hack, the real solution is probably to push a lot of
ATAPI state into the migration stream, but this is a fix that
works with no stream changes. Tested only on Linux (both RHEL5
(pre-libata) and RHEL7).

SCSI devices have multiple kinds of queries they need to respond
to, as defined in the "cmd inquiry" section in MMC-6 and SPC-3.
Relevent sections:
MMC-6 revision 2g:
Non-VPD response data and pointer to SPC-3;
Section 6.8 "Inquiry Command"
SPC-3 revision 23:
Inquiry command and error handling:
Section 6.4 "INQUIRY command"
VPD data pages format:
Section 7.6 "Vital product data parameters"
We implement these Vital Product Data queries for SCSI, but not for
ATAPI through IDE. The result is that if you are looking for the WWN
identifier via tools such as sg3_utils, you will be unable to query
our CD/DVD rom device to obtain it.
This patch adds the minimum number of mandatory responses as defined
by SPC-3, which include the "supported pages" response (page 0x00)
and the "Device Identification" response (page 0x83). It also correctly
responds when it receives a request for an illegal page to improve
error output from related tools.
The Device ID page contains an arbitrary list of identification
strings of various formats; the ID strings included in this patch
were chosen to mimic those provided by the libata driver when
emulating this SCSI query (model, serial, and wwn when present.)
Example:
# libata emulated response

Device models should access their block backends only through the
block-backend.h API. Convert them, and drop direct includes of
inappropriate headers.
Just four uses of BlockDriverState are left:
* The Xen paravirtual block device backend (xen_disk.c) opens images
itself when set up via xenbus, bypassing blockdev.c. I figure it
should go through qmp_blockdev_add() instead.
* Device model "usb-storage" prompts for keys. No other device model
does, and this one probably shouldn't do it, either.
* ide_issue_trim_cb() uses bdrv_aio_discard() instead of
blk_aio_discard() because it fishes its backend out of a BlockAIOCB,
which has only the BlockDriverState.
* PC87312State has an unused BlockDriverState[] member.

When the command completion code in IDE and AHCI
was unified to put all command completion inside
of a callback, "cmd_done," we neglected to
ensure that all AHCI/ATAPI command paths would
eventually register as finished. for the PCI
interface to IDE this is not a problem because
cmd_done is a nop, but the AHCI implementation
needs to send a D2H_REG_FIS and interrupt back
to the guest to inform of completion.
This patch adds calls to ide_stop_transfer,
which calls ide_cmd_done, inside of
ide_atapi_cmd_ok and ide_atapi_cmd_error.
This fixes regressions observed by trying to boot QEMU
with a Fedora 20 live CD under Q35/AHCI, which uses
ATAPI command 0x00, which is a status check that may
cause a hang because we never complete, and ATAPI
command 0x56, which is unsupported by our current
implementation and results in an error that we never
report back to the guest.

1. Device models using bdrv_eject(), currently ide-cd and scsi-cd.
They expect bdrv_is_inserted() to reflect the tray status. Commit
4be9762a makes them happy.
2. Code that wants to know whether a BlockDriverState has media, such
as find_image_format(), bdrv_flush_all(). Commit 4be9762a makes them
unhappy. In particular, it breaks flush on VM stop for media ejected
by the guest.
Revert the change to bdrv_is_inserted(). Check the tray status in the
device models instead.

to guest originating I/O
- we do not double count I/O ops if the device model handles it
chunk wise
- we only account I/O once it actuall is done
- can extent I/O accounting to synchronous or coroutine I/O easily
- implement I/O latency tracking easily (see the next patch)
I've conveted the existing device model callers to the new model,
device models that are using synchronous I/O and weren't accounted
