mycroft 3dcff6581b Use the new trigger_{in,out}put interface.
Also, even on the SB1, we can leave the DMA controller in auto-initalize
mode and just send a command to the board for each block.  This may help
prevent FIFO underruns.

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).

thorpej 3be1ffe6a0 When hooking up the interrupt handler, use an interrupt share type
specified by the front-end.

thorpej 5f97398507 Adjust for changes to the ISA DMA API. 1998-06-09 00:05:44 +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 b2004a534c Make sure the 'input' class is used even for the 1345 mixer. 1997-10-16 23:34:57 +00:00
augustss 7886f60e81 Make SB full duplex. Ooops, I forgot this in the last commit. 1997-08-30 10:45:32 +00:00
augustss cd7e93c44d Add mute and channels swap to the mixer capabilites. 1997-08-24 23:50:40 +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.

augustss c392128002 Audio:
* Make it possible to use software assisted encodings that expand the
  sample size.
* Use 16 bits per sample when emulating mulaw coding on the SB.
* Prepare for SB16 without CT1745 mixer.
1997-08-04 09:29:51 +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.

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.

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.

thorpej 11e78a6b0d Pull thorpej-bus-dma branch into mainline. 1997-06-06 23:43:45 +00:00
augustss 72b5ba3901 Redo the way selecting the mode for SB cards is done completely.
It is now table driven since there are so many different variations
of SB cards out there.
Also fix a bug that stopped SB2 and SBPro from working.
1997-05-23 21:19:59 +00:00
augustss 0db08d11e6 Redo the SB mixer code. The driver can now distinguish between the
four different mixer options: none, CT1335, CT1345, and CT1745.
It should now be possible to access most of the SB16 functionality.

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 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.

mycroft 6f51eb5c3d Use autoinitialize DMA mode on the SB2 and later. Partly from Torsten Duwe. 1997-03-20 21:42:11 +00:00
mycroft 95abb133dc Add 16-bit DRQ support on PnP, and enable 16-bit output. 1997-03-20 11:03:10 +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.

christos e6717c0bc9 - convert to bus_space_*

christos 1c86bef3bc Fix gcc -Wall warnings. 1996-04-29 20:28:40 +00:00
jtk 8b3873367f add MediaVision Jazz16 chipset support. It must be configured with
'flags 1' on the sb? kernel configuration file line (because it frobs a
noncontiguous IO port to configure the Jazz16 extensions).

Also, remove static sb_device structure and fill in user's buffer on
each request.

mycroft 546ad9e88b Add support to the ISA DMA framework for auto-initialize mode.
Add experimental SB16 code, disabled for now.

mycroft 7847c9efee Various:
* Snap the sample rate when setting it, and remember only the time constant.
* Set the time constant when changing between play/record.
* Always return the actual sample rate with AUDIO_GETINFO.
1996-02-16 10:10:21 +00:00
mycroft 7af4edd731 Various, including:
* Add more delays while writing registers.
* Replace sc_dma{in,out}_inprogress with sc_dmadir.
* Eliminate the need for sc_locked.
* Add more DPRINTF()s.

cgd 8a640328ed clean up several ISA device interfaces: autoconfiguration, header
inclusion, and interrupt configuration.  more work still needs to be done,
but it's getting better...
