jonathan dbe5213b11 Split arch/sparc/dev/amd7930.c into:
* MI sys/dev/ic/{am7930.c,am7930var.h} chipset driver
  * sparc frontend.
Presere revision history (this time).

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

chuck d76941843e 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

augustss e7029fc0da 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.

augustss 6616d47838 - 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 332ad95e76 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.

augustss 658656bb99 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.

augustss a63034762b 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.

augustss d58bc6796f audio: Simplify handling of AUDIO_SETFD and committing of encoding mode. 1997-07-27 23:51:48 +00:00
augustss 9745684ebe 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.

augustss e63a553175 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.

augustss c4a52794f1 Convert to new orthogonal audio encoding scheme and implement
some of the new encodings.  The change to ioctl AUDIO_GETENC is
NOT backwards compatible.

augustss 526ef2f618 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.

thorpej 3cd14f7597 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.
