isaki | Improve am7930 family drivers to share more code.
audioamd(4) on sparc, vsaudio(4) on vax, and bba(4) are.
- Remove complex and useless callbacks: onopen, onclose, and
indirect_{read,write}. This makes audioamd and vsaudio almost the same.
- Remove (already disabled) assembly fast interrupt path from audioamd(4).
cf. http://mail-index.netbsd.org/source-changes/2009/12/19/msg004585.html
- Use trigger_* method rather than start_* method. It's more suitable.
vsaudio(4) was tested by naru@, bba(4) was tested by tsutsui@.

isaki | Clean get_props().
- Make get_props() return AUDIO_PROP_{PLAYBACK,CAPTURE} properly.
This eliminates need for audio.c to take care of such (old)
drivers which don't return both of PLAYBACK and CAPTURE.
- All get_props() doesn't need to return AUDIO_PROP_MMAP.
It is handled in the audio layer now.

isaki | Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).
Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c
- dev/audiobellvar.h -> dev/audio/audiobellvar.h
- dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

jmcneill | branches: 1.51.8; 1.51.26;
Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From
the original ad-audiomp branch notes:
Add MP locking to the audio drivers.
Making the audio drivers MP safe is necessary before efforts
can be made to make the VM system MP safe.
The are two locks per device instance, an ISR lock and
a character device lock. The ISR lock replaces calls to
splaudio()/splx(), and will be held across calls to device
methods which were called at splaudio() before (e.g.
trigger_output). The character device lock is held across
calls to nearly all of the methods, excluding some only
used for initialization, e.g. get_locks.

kent | merge kent-audio1 branch, which introduces audio filter pipeline to the MI
audio framework
Summary of changes:
* struct audio_params
- remove sw_code, factor, factor_denom, hw_sample_rate,
hw_encoding ,hw_precision, and hw_channels. Conversion information
is conveyed by stream_filter_list_t.
- change the type of sample_rate: u_long -> u_int
- add `validbits,' which represents the valid data size in
precision bits. It is required in order to distinguish 24/32bit
from 24/24bit or 32/32bit.
* audio_hw_if
- add two parameters to set_params()
stream_filter_list_t *pfil, stream_filter_list *rfil
A HW driver should set filter recipes for requested formats
- constify audio_params parameters of trigger_output() and
trigger_input(). They represent audio formats for the hardware.
- make open() and close() optional
- add int (AUMODE_PLAY or AUMODE_RECORD) and audio_params_t parameters
to round_blocksize()
* sw_code is replaced with stream_filter_t.
stream_filer_t converts audio data in an input buffer and writes
into another output buffer unlike sw_code, which converts data in
single buffer.
converters in dev/auconv.c, dev/mulaw.c, dev/aurateconv.c,
dev/tc/bba.c, dev/ic/msm6258.c, and arch/arm/iomd/vidcaudio.c are
reimplemented as stream_filter_t
* MI audio
- audiosetinfo() builds filter pipelines from stream_filter_list_t
filled by audio_hw_if::set_params()
- audiosetinfo() returns with EINVAL if mmapped and set_params()
requests filters
- audio_write(), audio_pint(), and audio_rint() invoke a filter
pipeline.
- ioctl() for FIONREAD, AUDIO_WSEEK, AUDIO_GETIOFFS,
AUDIO_GETOOFFS, and audio_prinfo::{seek,samples} for
AUDIO_GETINFO handle values for a buffer nearest to userland.
* add `struct device *' parameter to ac97_attach()
* all of audio HW drivers follow audio_hw_if and ac97 changes

chuck | fix mixer code that was clearly untested:
- allow get/set of enums SUNAUDIO_SOURCE and SUNAUDIO_OUTPUT rather
than returning EINVAL
- add missing SUNAUDIO_MONITOR_CLASS case in query_devinfo
- convert SUNAUDIO_MONITOR case from a MIXER_CLASS to a MIXER_VALUE
like it is supposed to be
- the labels for outputs/record class were swapped: fix it
this patch allows "mixerctl" to work properly on a sparc

The changes is to allow some limited mixer manipulation through

augustss | - Change audio_hw_if a little: set_param now sets the play and record modes
at the same time instead by using two different calls. This enables
it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
play and record settings are independent.
- Fix some buglets in audio.c.

augustss | Audio changes:
- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw
convertsion when they are not needed. Add 16 bit alaw/mulaw tables.
- Change the way audio properties are gotten.

augustss | audio: Simplify handling of AUDIO_SETFD and committing of encoding mode.

| 27-Jul-1997 |
augustss | Changes to the sudio system:
- It is now possible to handle devices that want "looping" DMA,
e.g. the SoundBlaster correctly. The WSS and SB drivers use this.
To do this several new methods were introduced in audio_hw_if.
- Different silence handling (forced by previous change).
- The audio driver can now be mmap()-ed, but due to problems in
the VM system only for writing for now.
- The OSS (Linux) audio emulation takes advantage of some of the
new features.

Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface

and flexible.

isaki | Adapt am7930 families to audio2.
- Remove {input/output}_conv stuff from am7930_glue.
Filter pipelines for user encoding are not necessary in audio2
so the driver only needs to handle its hardware encoding.
- audioamd/vsaudio use an ordinal linear-mulaw conversion filter
and bba requires special one. dev/audio/mulaw.c supports this
variant just for bba. It might not a good way for bba but it
keeps all other drivers simple.
- Tested on vsaudio(4) by naru@, bba(4) by tsutsui@ (a few months ago).
Thanks!
