thorpej 3be1ffe6a0 When hooking up the interrupt handler, use an interrupt share type 
specified by the front-end.
 1998-06-29 22:40:56 +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 06ce220790 Update for config changes. 1998-01-12 09:39:57 +00:00
augustss dd95190002 XXX Workaround for ViBRA cards with two 8 bit DMA channels. 1997-11-12 20:28:42 +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
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 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 c612a6fca7 Check that setting IRQ and DRQ on SB16 actually succeeds. 1997-05-23 09:45:40 +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 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 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.

to isa_intr_{,dis}establish().
 1996-04-11 22:27:59 +00:00
thorpej 6d9ea4cf59 New device attachment scheme: 
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.
 1996-03-17 00:43:52 +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.
 1996-03-16 04:00:09 +00:00

but it's getting better...
