I hope it will help new users easier accept concept of several PCM devices
and understand exact purposes of that devices.
with several points unappropriate for the present parser. This patch
disables input-to-output analog monitoring but instead fixes recording.
Tested by Tobias Grosser on ThinkPad T61p.
When I changed kern_conf.c three months ago I made device unit numbers
equal to (unneeded) device minor numbers. We used to require
bitshifting, because there were eight bits in the middle that were
reserved for a device major number. Not very long after I turned
dev2unit(), minor(), unit2minor() and minor2unit() into macro's.
The unit2minor() and minor2unit() macro's were no-ops.
We'd better not remove these four macro's from the kernel, because there
is a lot of (external) code that may still depend on them. For now it's
harmless to remove all invocations of unit2minor() and minor2unit().

Left only parts surely required for basic troubleshooting and configuration
purposes. There is still very long output, but further shrinking makes it
less informative.
Original debugging can be enabled with hw.snd.verbose=4.
Because of using more clear and same time more functional codec parser
new driver is able to handle more codecs, use them better then before and
without most of previous quirks. All of tested codecs itself manage playback,
record, input mixing and monitoring quite fine. In all of investigated
trouble cases problem was found or in nonstandard codec usage or incorrect
codec configuration made by BIOS. Most of that cases could be fixed using
device hints, some of which are already included to the driver.
New driver supports multiple codecs per HDA bus, multiple audio function
groups per codec and multiple logical sound devices per audio function group.
So don't worry when you get several PCM devices instead of one, it is normal.
It is usual situation with powerful codecs to provide, for example, 3 PCM
devices: one for 7.1 playback and main recording, one for headset and one
for digital SPDIF I/O.
New driver implements Universal Audio Architecture (UAA) much better then
previous one. Most information about recommended codec usage now taken from
the codec configuration registers initialized by BIOS. User may alter that
configuration using device hints to reconfigure logical audio devices to
his needs in a very broad range up to the limits of the codec functionality.
New driver supports digital PCM playback and AC3 pass-through. I am not sure
about completeness of this implementation, but I have several success stories
including my own. Vchans subsystem does not support AC3 pass-through so it
had to be disabled for that devices at this moment.
New driver is ready for multichannel playback, but until our OSS is unable
to use this it will just duplicate same stereo stream into all channel
pairs.
New driver supports suspend/resume. I am unable to really test this part
myself, but I have got several success stories.
Driver has very informative verbose boot messages. So if you have any
questions or problems - enable and read them first.

(without any real order)
1. Use device_get_nameunit for mutex naming
2. Add timer for low-latency playback
3. Move most mixer controls from sysctls to mixer(8) controls.
This is a largest part of this patch.
4. Add analog/digital switch (as a temporary sysctl)
5. Get back support for low-bitrate playback (with help of (2))
6. Change locking for exclusive I/O. Writing to non-PTR register
is almost safe and does not need to be ordered with PTR operations.
7. Disable MIDI until we get it to detach properly and fix memory
managment problems.
8. Enable multichannel playback by default. It is as stable as
single-channel mode. Multichannel recording is still an
experimental feature.
9. Multichannel options can be changed by loader tunables.
10. Add a way to disable card from a loader tunable.
11. Add new PCI IDs.
12. Debugger settings are loader tunables now.
14. Remove some unused variables.
15. Mark pcm sub-devices MPSAFE.
16. Partially revert (bus_setup_intr -> snd_setup_intr) since it need

since 2.2.x - 3.x (the introduction of newpcm). Full-duplex mmap still
doesn't work (due to VM/page design), but people still can mmap
both by opening each direction separately. mmaped playback is guarantee
to work either way.
- New sysctl: "hw.snd.compat_linux_mmap" to allow PROT_EXEC page
mapping, due to recent changes in linux compatibility layer which
require it. All linux applications that using sound + mmap() (mostly games)
require this to be enabled. Disabled by default.
