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@.

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.

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.

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.

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

Update for changes to config.

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

branches: 1.33.2;
Make this compile again.

Make the audio API (almost) SunOS compatible.
The changes is to allow some limited mixer manipulation through
the audio device (instead of the mixer device).
This rendered 4 methods in audio_hw_if unused so garbage collect these.

AudioC[A-Z] -> AudioC[a-z]
AudioElinear -> AudioEslinear

Change match routine to use "audio" as the ROM name.

Fix prototype for amd7930_set_params.

- 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.

Change the MI audio driver so it attaches to the MD driver in the
normal way. This requires adding a line to the config files to
get audio to work again.

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.
- Recognize more versions os SoundBlaster.

branches: 1.25.2;
Audio: Remove the machine dependant code I put in audio.c by mistake.
This adds another method to audio_hw_if. Also remove a field from

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

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.

Remove all `bustype' arguments from map[io]dev() and REG2PHYS().

Tweak gain curve (from nsayer@kfu.com; PR#2909)

Change the interface between high and lowlevel audio drivers again:
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.

Convert to new orthogonal audio encoding scheme and implement
some of the new encodings. The change to ioctl AUDIO_GETENC is
NOT backwards compatible.

Change the interface between the high and low level audio drivers
so that all audio encoding parameters are set at once. This simplifies
the interface and make error checking easier.

Implement set_format.

Don't share the silence block between devices. Make silence filling work for
more encodings, and make it device-independent. From Lennart Augustsson, in
PR kern/3305.

Comply with recent autoconfiguration changes. Diffs graciously

Various cleanup; mostly trailing spaces/tabs.

New device attachment scheme:

- split softc size and match/attach out from cfdriver into

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

Change match routine to use "audio" as the ROM name.

Fix prototype for amd7930_set_params.

- 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.

Change the MI audio driver so it attaches to the MD driver in the
normal way. This requires adding a line to the config files to
get audio to work again.

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.

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

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.

Remove all `bustype' arguments from map[io]dev() and REG2PHYS().

Tweak gain curve (from nsayer@kfu.com; PR#2909)

Change the interface between high and lowlevel audio drivers again:
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.

Convert to new orthogonal audio encoding scheme and implement
some of the new encodings. The change to ioctl AUDIO_GETENC is
NOT backwards compatible.

Change the interface between the high and low level audio drivers
so that all audio encoding parameters are set at once. This simplifies

a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached

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.

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

- Fix some buglets in audio.c.

Change the MI audio driver so it attaches to the MD driver in the
normal way. This requires adding a line to the config files to
get audio to work again.

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.
- Recognize more versions os SoundBlaster.

Audio: Remove the machine dependant code I put in audio.c by mistake.
This adds another method to audio_hw_if. Also remove a field from
audio_hw_if that was not read-only.

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

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.

Remove all `bustype' arguments from map[io]dev() and REG2PHYS().

Tweak gain curve (from nsayer@kfu.com; PR#2909)

Change the interface between high and lowlevel audio drivers again:
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.

Convert to new orthogonal audio encoding scheme and implement
some of the new encodings. The change to ioctl AUDIO_GETENC is
NOT backwards compatible.

Change the interface between the high and low level audio drivers
so that all audio encoding parameters are set at once. This simplifies
the interface and make error checking easier.

Implement set_format.

Don't share the silence block between devices. Make silence filling work for
more encodings, and make it device-independent. From Lennart Augustsson, in
PR kern/3305.

Comply with recent autoconfiguration changes. Diffs graciously

Drop in a sun4m version of AUDIO_SET_SWINTR; thanks to Nick Sayer for
the reminder.

backout previous kprintf change

printf -> kprintf, sprintf -> ksprintf

count audio interupts (from OpenBSD).

Various cleanup; mostly trailing spaces/tabs.

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

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.

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

Use bus_space tags and handles, embedded in MD hooks AM7930_{READ_WRITE}_REG
to handle MD delay and bus padding. Tested on sparc2 by David Brownlee.

Should use regmaps, but that breaks sparc pDMA assembly code.

Nuke Dprintf; fix formats.

Split arch/sparc/dev/amd7930.c into:

* sparc frontend.
Presere revision history (this time).

TODO: bus.h'ify, and padded register mappings.

Fix some arithmetics lossage on typeless pointers.

Replace direct `sparc_bus_map()' calls with bus space map method.

Account for changed bus attachment scheme.

Update for changes to config.

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

branches: 1.33.2;
Make this compile again.

Make the audio API (almost) SunOS compatible.
The changes is to allow some limited mixer manipulation through
the audio device (instead of the mixer device).
This rendered 4 methods in audio_hw_if unused so garbage collect these.

AudioC[A-Z] -> AudioC[a-z]
AudioElinear -> AudioEslinear

Change match routine to use "audio" as the ROM name.

Fix prototype for amd7930_set_params.

- 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.
