augustss 33f1482ece Make sure recording is started before we return EWOULDBLOCK in a read(). 1998-12-27 23:25:32 +00:00
augustss 496387c419 Fold lines to 80 chars. 1998-12-27 22:52:23 +00:00
drochner 6292c7eda0 Make midi_attach_mi() and audioprint() available also if MIDIBUS 
(but not necessarily MIDI) is defined.
Fixes PR port-i386/6615 (Krister Walfridsson <cato@ulysses.df.lth.se>).
(XXX this should probably go into a separate file to get rid of
the #ifdef mess)
 1998-12-20 14:26:44 +00:00
mycroft 53698488ff Do not permit a class to be recorded as a master or monitor port. 1998-11-25 13:44:13 +00:00
mrg db3051d720 fix problems in many d_mmap routines: 
- returned EOPNOTSUPP rather than -1.
	- no check for negative offset.
many of these fix potential security problems in these drivers.


XXX XXX XXX
the d_mmap cdev routine should be changed to have a prototype like:
	paddr_t (*d_mmap) __P((dev_t, off_t, int));

by someone!

christos b12bfa760e Make this compile again with no audio but with midi devices. 1998-09-27 16:43:56 +00:00
mycroft b742b9ad67 Move some debugging output to more useful levels. 1998-09-01 07:27:06 +00:00
pk 535cdbe9f2 Slight optimization in audio_[pr]int(). 1998-08-28 12:07:41 +00:00
augustss c50af72c34 Handle the case of MIDI devices with no audio devices. 1998-08-28 07:44:12 +00:00
thorpej 1083dcb6ca Back out previous. 1998-08-18 18:16:30 +00:00
thorpej 73d1752963 Deal with somewhat bogus uninitialized warning in new egcs. Behavior 
is such that would inidicate that __attribute__((__noreturn__)) is not
being honored.

augustss cd09067eb4 * Redo the way the way the MIDI driver attaches to audio devices. 
* Improve the midisyn layer a little.
* Add a driver for the Yamaha OPL[23] FM synths.
  The opl driver is not finished yet; it sounds pretty awful.

For some strange reason I cannot get any FM sound from my SB64 cards,
but a regular SB16 works fine.

mycroft 20ec08b84e Oops. 1998-08-10 01:17:33 +00:00
mycroft 10148394d2 Call set_params if usemode changes. 1998-08-10 01:13:20 +00:00
mycroft 17431823fb Add trigger_output and trigger_input entry points, which replace 
init_{in,out}put and start_{in,out}put, and are only called once.
 1998-08-09 20:28:07 +00:00
mycroft a2fc689833 Make sure output is thoroughly halted on close, and remember that we stopped 
it.
 1998-08-09 07:25:58 +00:00
mycroft 9bedf069cd Mask off extra usemode bits. 1998-08-09 05:44:51 +00:00
mycroft b3853549b3 Always copy back both the record and play parameters, in case the driver had 
to change one behind our back.
 1998-08-09 04:54:44 +00:00
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).

augustss 28e2d6024a Clarify a comment. 1998-08-05 16:38:09 +00:00
augustss 5b057ab09f Allow option AUDIO_INTR_TIME even if the platform does not support 
FP in the kernel.

mycroft f37f08c48e This doesn't need opt_compat_netbsd.h any more. 1998-07-09 09:27:33 +00:00
mycroft 401accfd7a Don't #ifdef the encoding compatibility crud. It's needed for source 
compatibility with other systems and much third party software.
 1998-07-09 02:45:45 +00:00
jonathan d275e56dee * defopt COMPAT_{09,10,11,12,13} and COMPAT_NOMID. 
TODO: revisit interaction between native compat and emul compat usage.

augustss 54281b8662 Avoid spaces in tsleep() string. 1998-05-18 18:27:43 +00:00
augustss 88edb37522 Be more verbose if attaching the audio device fails. 1998-05-15 15:45:58 +00:00
augustss df71a424d6 Change debug printing a littel again. 1998-04-28 23:19:20 +00:00
augustss 127acabd9c Add a few more debug messages and clean up debug printing a little. 1998-04-28 09:07:12 +00:00
augustss 44c6ce78d2 Avoid the name free so the MALLOCLOG option works again. 
Fix some typos.
 1998-03-03 09:16:15 +00:00
thorpej 43ba4e27bd Adjust for config changes. 1998-01-12 08:44:08 +00:00
augustss a908b2b30e Fix three problems spotted by mycroft: 
- Closing the audio device should stop recording.
- Manipulating the pause function could accidentally start playing or recording.
- AUDIO_FLUSH could accidentally start playing or recording.
 1997-12-03 01:01:19 +00:00
augustss b366d54e2e Fix slight glitch in last commit when AUDIO_DEBUG is on. 1997-10-29 02:11:45 +00:00
augustss 9f84e63746 Do audio attachment the right way. From Chris Demetriou. 
(Maybe I'll get the hang of the configuration stuff one of these days. :-)
 1997-10-29 02:00:20 +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.
 1997-10-19 07:41:33 +00:00
is 25ea46120a TMS320AV110 (mpeg layer 2 decoder chip) and ZBUS Melody board, which uses it. 
No optionboards yet for Melody, only audio driver.
MPEG data types for audio.c

augustss 31ab81c6e4 Aignore interrupts if the device isn't open. 1997-10-16 16:41:18 +00:00
augustss 0d79fbe5c5 Don't test for unused methods. 1997-10-14 18:43:42 +00:00
mycroft 3cdff9d435 GETPROPS does not indicate whether the device is currently in full-duplex 
mode.  Reinstate GETFD to return this information.
 1997-10-11 11:16:28 +00:00
augustss 4f2068ec29 Sanity check hi/lo water mark settings better. 1997-10-07 22:40:43 +00:00
augustss ffcdaf144d Move around splaudio() to (hopefully) get rid of some rare race conditions. 
Add a missing call to round_blocksize.
Add some MIDI stuff that will be used in the future.
 1997-09-06 01:14:48 +00:00
thorpej d2a9d1970d Don't deference a bad pointers if you try to open an audio device that's 
not configured.
 1997-08-27 18:54:28 +00:00
augustss 955e1e9119 Make sure audio device starts in half-duplex mode and document the fact. 1997-08-26 19:03:55 +00:00
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.
 1997-08-24 22:31:23 +00:00
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.
 1997-08-19 23:49:33 +00:00
augustss e5b75f05d4 Make a slight change to when blocksize, hi- and lo-water marks are 
recalculated.  The new semantics is more intuitive(?) and makes Doom
work :-)
 1997-08-18 23:20:09 +00:00
augustss 34085fae66 Implement /dev/audioctl. It behaves much like /dev/sound, but only 
allows ioctl() and can be opened at any time.
 1997-08-18 21:19:02 +00:00
augustss 8f096d087f Implement delivery of SIGIO on changes to /dev/mixer. 1997-08-11 01:38:12 +00:00
augustss 9a770a177f Make setting the audio block size sticky. 
Change the calculated block size to correspond to 50 ms of sound
(was 20 ms, it seems needlessly small).
 1997-08-08 00:03:26 +00:00
augustss 3c6f8bc89e Restructure a little to make sure AUDIO_FLUSH restarts the looping DMA. 1997-08-06 23:08:26 +00:00
