augustss fb4a4525a8 Be cautious about the blocksize returned by the hardware driver to 
avoid division by 0.

kleink 9dfb5a91ec Minor output formatting buglet. 1999-09-23 11:53:13 +00:00
augustss a85a08c2fb Add support for detaching audio devices. 1999-09-09 10:24:39 +00:00
thorpej 12006f3c05 Don't clobber the error returned by uiomove() when starting the audio 
output (in case we got a partial block).  Fixes PR #7722, from
Antti Kantee <pooka@iki.fi>.
 1999-06-07 19:24:38 +00:00
nathanw 9e14ee3c6e Fix two small bugs: 
(1) Fix sense of a strcmp() test so that the monitor subdevice of the
    mixer is properly identified.
(2) Use hw_if->set_port() instead of hw_if->get_port() when changinh
    the monitor level in audiosetinfo().

Fixes PR kern/7661.

nathanw ea0550413c Make these compile on the alpha when AUDIO_DEBUG is defined. 1999-02-26 01:18:09 +00:00
mycroft 35399992bb Indicate whether the decive is full or half duplex at attach time. 1999-02-19 17:09:16 +00:00
mycroft e5f5e628d2 Pass the direction to the allocm and round_buffersize methods. 
Some drivers need this to properly allocate DMAable memory.
 1999-02-17 02:37:38 +00:00
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!

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.
 1998-08-18 06:16:45 +00:00
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.
 1998-08-17 21:16:09 +00:00
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 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 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.

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.

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
