mycroft 97de30ff26 Several things:
* Rearrange the speed mapping table and adjust the code so that the highest
  rate can actually be used.  Previously we ended up rounding up slightly
  lower speeds and then losing because set_params couldn't set the mode
  back to the current one.
* Allow 260 as a valid I/O address, since the SB1 can be jumpered to this.
* Change the MPU-401 code so it can be attached as a separate device.
  (XXX Really, the SB code ought to just attach a subdevice itself.)
* Do not attach an OPL on the SB1.  Writing to the OPL registers at
  SB_base+0 on this card wedges my machine.
  (XXX Should we access it at 388 instead?  The Creative web site claims
  that this board *does* have an OPL2, but I haven't played with this
  extensively.)
* Allocate the SB DMA channels at open time, rather than attach time, so
  that a single DRQ can be used for multiple cards (if only one is in use
  at a given time).
  (XXX Let me tell you why this is a horrible hack.  If the ISA DMA code
  tries to allocate a bounce buffer after boot time, it will generally fail,
  because there is no contiguous memory below 16MB and the code to allocate
  contiguous pages doesn't know how to move things around.  Now, we
  shouldn't ever be using bounce buffers here, because we use
  isa_dmamem_alloc().  So we just turn off BUS_DMA_ALLOCNOW and we don't
  actually try to.  That's cool, and it even works, but isa_dmamem_alloc()
  has the same problem.  It just happens that we allocate the ring buffers
  at boot time, and whenever we reallocate them (due to the buffer size
  changing), we just deallocated the previous (contiguous) buffer, so we get
  lucky.  This is absolutely disgusting and needs to be fixed.)

mycroft 5e2fc07a14 Add separate halt_output and halt_input routines. 1999-02-18 07:08:35 +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.

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 0bb9a48c65 Give names to some more mixer registers. 1997-08-24 23:24:51 +00:00
augustss b99285b1e4 Round mixer values correctly when setting them.
This is important for the OSS emulation since OSS
uses a different range of values for the mixer.

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 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.

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
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 29414c5a0a Change all of the uses of IRQ{0-15} and bit masks to use plain numbers
rather than bit shifting.

mycroft 592ec61b17 Updates for new autoconfig. 1994-03-29 04:35:37 +00:00
cgd 3f787778b2 LBL /dev/audio and soundblaster drivers, as ported by brad@fcr.com.
both should work with both old- and new-config i386 trees.
Some notes:
	bsd_audio.c has dependencies on the soundblaster.  This should
		be fixed, so that it can be used for the PC speaker
		(when its driver has been modified), as well.
	sb.c needs some cleanup, and will have sections trimmed, eventually
		(when new config becomse standard for i386).  additionally,
		the SBPro support needs some cleanup.
