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.

Right now, DeviceInfo acts as the class for qdev. In order to switch to a
proper ObjectClass derivative, we need to ween all of the callers off of
interacting directly with the info pointer.

commit ba43d28916 introduces a bug:
The stream-not-found case doesn't error out any more, instead the
code silently uses the first stream. Fix it.

This updates the intel-hda device emulation to use the explicit PCI DMA

SCSI buses will need to read the children list first-to-last. This
requires using a QTAILQ, because hell breaks loose if you just try
inserting at the tail (thus reversing the order of all existing
visits from last-to-first to first-to-tail).

Windows 7 may use the same stream number for input and output.
Current code will confuse streams.

Windows 7 may use the same stream number for input and output.
That will result in lot of garbage on playback.
The hardcoded value of 4 needs to be in sync with GCAP streams
description and IN/OUT registers.

This was done with:
sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
$(git grep -l 'qemu_get_clock\>' )
sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
$(git grep -l 'qemu_new_timer\>' )
after checking that get_clock and new_timer never occur twice
on the same line. There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.
There was exactly one false positive in qemu_run_timers:
- current_time = qemu_get_clock (clock);
+ current_time = qemu_get_clock_ns (clock);
which is of course not in this patch.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

The HDA bus supports up to 15 codecs, with addresses 0 ... 14.
We get that wrong in two places:
* When handing out addresses we accept address 15 as valid.
* The bitmasks for two registers (WAKEEN and STATESTS) don't
have bit 14 set.
This patch fixes it.

This patch adds three devices to qemu:
intel-hda
Intel HD Audio Controller, the PCI device. Provides a HDA bus.
Emulates ICH6 at the moment. Adding a ICH9 PCIE
variant shouldn't be hard.
hda-duplex
HDA Codec. Attaches to the HDA bus. Supports 16bit stereo,
rates 16k -> 96k, playback, recording and volume control
(with CONFIG_MIXEMU=y).
hda-output
HDA Codec without recording support. Subset of the hda-duplex
codec. Use this if you don't want your guests access your mic.
Usage: add '-device intel-hda -device hda-duplex' to your command line.
Tested guests:
* Linux works.
* Win7 works.
* DOS (mpxplay) works.
* WinXP doesn't work.
[ v2 changes ]
* Fixed endianess, big endian hosts work now.
* Fixed some emulation bugs.
* Added immediate command emulation.
* Added vmstate support.
* Make it behave like all other sound card drivers:
- can be configured via '--audio-card-list=hda'
- can be added to a VM using '-soundhw hda'
* Code style fixups.
* Zapped guest-triggerable asserts.
* Handle partial reads/writes of audio data correctly.
