itohy 2b98e16426 Oops! Make it compile again. 1999-10-07 08:16:51 +00:00
itohy a44328a50e Fix power-related init code.
Change the default mixer setting to make wave and OPL3 volume even.
Mute the chip during attach not to make noise.

itohy 871f1c2c0a New ym driver.
1. Add power control to reduce power consumption.
    The behavior can be controlled by mixerctl(1).
 2. Add suspend/resume hook to keep the parameters.
    Currently this includes CODEC and control registers but
    does not include the DMA state.  FIXME.
 3. Support "opl at ym" and "mpu at ym" attachment.
    Actually, this is required for power control.
 4. Add support for the on-chip 3D enhancement hardware.
    This includes bass/treble enhancement, wide stereo, and
    the equalization mode.  This can be controlled by mixerctl(1).
 5. Make "audioctl -w play.gain=xxx" work like as
    "mixerctl -w inputs.dac=xxx" and now it changes
    the wave output volume correctly.
 6. Support hardware master volume switches.
 7. Change formula of calculating gain so that all the levels
    should be used equally.
 8. Change "audioctl name" to "OPL3-SA3" and "audioctl version"
    to the version of the chip.

mycroft 18e341a954 Add separate halt_input and halt_output methods in ad1848_isa, which disable
the DMA channel.

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.

augustss 44d4d6a60a Call correct ad1848 attach routine. Fixes PR 6269. 1998-10-11 17:02:36 +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.

augustss 1f8eca312d Remove a bunch of totally unnecessary #include <machine/pio.h>
left over from the olden days.

augustss 0b9ec50365 Add a newline.
KNF.
