wiz 1ffa7b76c4 DMA, not dma nor Dma. 2003-05-03 18:10:37 +00:00
thorpej 60530be43c Fix sizeof and whitespace bug from the script I'm using to do the 
CFATTACH_DECL conversion.  (Grumble.)
 2002-10-02 03:10:45 +00:00
thorpej 0dac35b547 Use CFATTACH_DECL(). 2002-10-02 02:00:07 +00:00
thorpej f818766afe Declare all cfattach structures const. 2002-09-27 20:31:45 +00:00
christos b5d5702d16 Deal with lossage caused by recent isa changes [/briq potr] 2002-01-08 17:20:44 +00:00
thorpej 3835413bc1 Overhaul of the ISA autoconfiguration code to support direct 
configuration of devices logically attached to the ISA bus:

* Change the isa_attach_args to have arrays of io, mem, irq, drq
  resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
  isa_attach_args.  If either of these members are non-NULL,
  direct configuration of the bus is being performed.  Add an
  ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
  direct configuration is not being performed and the probe fucntion
  is returning success.
* Adapt device drivers -- currently, all driver probe routines return
  "no match" if ISA_DIRECT_CONFIG() evaluates to true.

lukem 3f7d8d47b6 add RCSID 2001-11-13 08:01:09 +00:00
augustss 1339e88a86 Add a new optional method, dev_ioctl, to the audio hardware driver interface. 
It is called when an unrecognized ioctl() is performed on a device,
thus allowing ioctl()s that frob the hardware driver (like loading
microcode).

thorpej ce623a36cc bzero -> memset 2001-07-18 20:39:53 +00:00
thorpej e5422a382f Explictly include <machine/pio.h> (since this driver uses 
i386 pio instructions -- XXX BROKEN).

mycroft 4449a6ef39 Kill vestiges of isa_establish(). 1999-02-19 16:15:06 +00:00
mycroft 18e341a954 Add separate halt_input and halt_output methods in ad1848_isa, which disable 
the DMA channel.
 1999-02-18 17:27:39 +00:00
mycroft 27963c294a Use the trigger interface, and clean up a pile of cruft. 1999-02-17 23:05:28 +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
dbj 8f7f8d557d made prototype for debug function wss_dump_regs match its definition. 1998-12-05 10:49:24 +00:00
cgd d58173741d kill the last remnants of __BROKEN_INDIRECT_CONFIG. (only the pica port 
used it, and it's non-working and apparently slated for replacement.)
 1998-08-31 22:28:04 +00:00
pk 2ffb54bdcc Split the AD1848 driver into MI (dev/ic/ad1848.c) and ISA parts. 1998-08-25 22:34:29 +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 fae3bf0887 Add a monitor mute. The mixer here really needs more work for the 
Crystal chips.
 1998-06-30 08:24:56 +00:00
augustss 1f8eca312d Remove a bunch of totally unnecessary #include <machine/pio.h> 
left over from the olden days.
 1998-06-17 08:17:25 +00:00
thorpej 5bc2217a49 Nuke __BROKEN_INDIRECT_CONFIG. 1998-06-09 07:24:55 +00:00
thorpej 5f97398507 Adjust for changes to the ISA DMA API. 1998-06-09 00:05:44 +00:00
augustss 74545baf39 Add a Yamaha OPL3-SA3 driver and clean up all AD1848 drivers. 
Submitted by Constantine Sapuntzakis <csapuntz@reeducation-labor.lcs.mit.edu>
and originally written for OpenBSD.
 1998-05-20 16:19:41 +00:00
augustss dbef68a11b Update for __BROKEN_INDIRECT_CONFIG. Still untested since it is so hard 
to find testers for these old cards.
 1998-03-23 01:00:21 +00:00
drochner 52c701add6 Make this file compile without BROKRN_INDIRECT_CONFIG. 
(Brute force - device probe always returns 0. Should be fixed soon.)
 1998-03-22 12:50:20 +00:00
augustss 09f43c63cf Update probing for GUS a little. From soren@t.dk, 
closes PR kern/5148.
 1998-03-12 12:28:50 +00:00
thorpej 06ce220790 Update for config changes. 1998-01-12 09:39:57 +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.

mycroft 2d019e5efd AudioC[A-Z] -> AudioC[a-z] 1997-10-11 11:28:49 +00:00
augustss 1cdcb2d362 Get rid of `register'. 1997-09-14 09:03:33 +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 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 d58bc6796f audio: Simplify handling of AUDIO_SETFD and committing of encoding mode. 1997-07-27 23:51:48 +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.
 1997-07-27 01:16:32 +00:00
thorpej 11e78a6b0d Pull thorpej-bus-dma branch into mainline. 1997-06-06 23:43:45 +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.
 1997-04-29 21:01:33 +00:00
augustss 7dcb9bed4c Make sure the bus tag is set where we need it. 1997-04-06 00:54:22 +00:00
augustss 7dedd37033 Busify the WSS driver. 1997-04-05 23:50:23 +00:00
mikel eba3c11c27 some cleanup; still needs a *lot* of work 1997-03-25 07:57:14 +00:00
mycroft c1cc14fa25 Combine set_encoding and set_precision into a single set_format interface. 1997-03-20 06:48:48 +00:00
mikel 80a8a81608 normalize off-by-four ad1848 register offsets. 1997-03-19 06:45:21 +00:00
mikel 8147d1718f fix various AD1848/PSS misfeatures; from Jason Baker in PR kern/2045. 
also did some misc cleanup of my own.
 1997-03-13 08:34:49 +00:00
mycroft ac3b8b13b7 Don't share the silence block between devices. Make silence filling work for 
more encodings, and make it device-independent.  From Lennart Augustsson, in
PR kern/3305.
