augustss 48bae9ee88 Add MIDI support. The MIDI devices can be accessed as ``raw'' through
the /dev/rmidiN devices, or with a sequencer interface via /dev/music.
So far the only supported MIDI device is the MPU401 port on SoundBlaster
(and only on SB on isapnp, since we do not have locators with multiple
values yet).

mycroft aa1112aed5 SETFRAGMENT ignores the high bit. 1998-03-19 06:53:28 +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 7002bab845 Emulate setting the hiwater mark with SETFRAGMENT the right way.
Get rid of some 'register'.

augustss 9390f073ca Increase the number of mixer devices the emulation looks at. 1997-08-24 23:31:23 +00:00
augustss 006a85ea00 Oops, forgot two lines in last commit. 1997-08-11 01:54:52 +00:00
augustss 67acd09fdc Implement OSS_SNDCTL_DSP_NONBLOCK. 1997-08-11 01:52:47 +00:00
augustss 2d2e53095a Some more debugging output. 1997-08-11 01:00:38 +00:00
augustss 46e0757329 Make sure OSS_SNDCTL_DSP_GETFMTS returns the formats the audio driver
can handle and not just some random guess.
Also add some debugging stuff.

augustss 7dfa17a43b Improve ioctl decoding.
Change mixer name mappings.

augustss d3de043fad Make sure the blocksize is always a power of 2 when inspected.
OSS only uses powers of 2 so some programs expect this.
Now Quake works!

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 c397fa8357 Return audio buffer size in audio_info_t with ioctl() AUDIO_GETINFO.
Use the buffer size to implement one more OSS ioctl().

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 32801cf383 * Move the Linux audio emulation into its own directory and rename it
OSS (aka VoxWare) audio emulation.
* Use the OSS audio emulation for Linux and FreeBSD.
* Add mixer emulation to the OSS emulator.

mycroft 41bbc3f5b6 SOUND_PCM_WRITE_CHANNELS -> SNDCTL_DSP_CHANNELS, to match current Linux code. 1997-03-20 04:21:31 +00:00
mycroft eb41ccd5fe Emulate the SOUND_PCM_WRITE_CHANNELS ioctl. From PR 3356, by Lennart
Augustsson.  Also add hooks for mixer ioctls.
