minoura 399af9e4a8 X68k built-in voice synthesizer supports 4bit ADPCM. 2001-05-02 12:49:41 +00:00
toshii b8569c0b8e The previous revision was my fault. audio_calcwater() needs to be 
called at every open.
Thanks Witold J. Wnuk for pointing out this problem.

toshii 577ac6e31c Remove the line in audio_open which zeroes sc_[pr]r.blksize. 
Because zeroing them causes zero division panic with devices which don't
support 8kHz mulaw, and the effect of this line was to force calling
audio_calcwater even when unnecessary.

augustss b85fdbbc47 Add a field in mixer_devinfo_t that indicates the minimum delta to 
change mixer value.  A value of 0 indicates that the driver doesn't
supply a delta.
The change is backwards compatible.

jmc 5b7fb2728a Back out changes from 1.124 since the additions of *ports.master=-1 wasn't 
documented as to why it was added in and it breaks the ability to set the
gain on playback. A longer term fix to set these correctly should be done but
none of the drivers today are doing this and not being able to set the playback
volume otherwise is a bit silly.

nathanw 554019cd4b More printf format munging for off_t: when printing as %lld, cast to long long. 2000-07-19 13:44:24 +00:00
thorpej cfaba33937 Use device_lookup(). 2000-07-06 00:43:04 +00:00
augustss d28770775b Make it compile with AUDIO_DEBUG after the mmap API change. 2000-06-27 21:25:02 +00:00
mrg f324eef2d2 remove include of <vm/vm.h> 2000-06-27 17:55:38 +00:00
simonb 889c658b5b Change the kernel mmap interface so that the offset to map is an 
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

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

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!

christos b12bfa760e Make this compile again with no audio but with midi devices. 1998-09-27 16:43:56 +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).

FP in the kernel.

mycroft 401accfd7a Don't #ifdef the encoding compatibility crud. It's needed for source 
compatibility with other systems and much third party software.
