augustss 09f43c63cf Update probing for GUS a little. From soren@t.dk, 
closes PR kern/5148.
 1998-03-12 12:28:50 +00:00
augustss d644f9b973 Apply cs4236 fix from rh@vip.at. Closes PR 5143. 1998-03-11 09:26:05 +00:00
cgd ccfe537e97 don't include <machine/pio.h>. It's unneeded here now (this code 
uses the bus_space_* interfaces), and therefore unwanted.
 1998-02-24 02:12:09 +00:00
augustss 6f6593a533 Fix initialization and timing problem. 
As per misc/4902, from Clifford Wright <cliff@snipe444.org>.

augustss 59d2219410 Split out the ISA part of the WSS driver to allow PnP attachment. 
Make the AD1848 driver a little more readable with some macros.
 1998-01-19 22:18:23 +00:00
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 a50d4ba893 XXX Add a drq2 locator for the ISA bus. Many sound cards need 
two DMA channels to do e.g. full-duplex.  This allows
a way of specifying the second channel in a sane way.
THIS IS TEMPORARY.  The drq2 locator will go away when
the locator system has been changed to allow multiple
values per locator.

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 1fea370221 Get rid of `register'. 1997-08-04 19:05:27 +00:00
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.
 1997-07-31 22:33:08 +00:00
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.
 1997-07-28 20:56:05 +00:00
augustss f6cd87f322 audio: Minor cleanup and enable looping DMA for PSS and PAS. 1997-07-28 01:31:50 +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 8727da130b In the name of backwards compatibility AUDIO_ENCODING_LINEAR has been 
renamed AUDIO_ENCODING_SLINEAR and AUDIO_ENCODING_LINEAR reverts to the
NetBSD 1.2 sematics.  A kernel with COMPAT_12 defined will accept
AUDIO_ENCODING_LINEAR and treat it as before, without COMPAT_12 it
will be rejected.

augustss 37be371415 Clean up emulation code, SB, and GUS drivers and add some more encoding 
emulation to SB.
 1997-05-13 19:02:11 +00:00
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.
 1997-05-09 22:16:27 +00:00
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.
 1997-05-07 18:51:31 +00:00
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.

mycroft e0b3534b6c Remove bogus block rounding code. If the application sets a 
block size explicitly, it had better know what it's doing.  From
