itohy d5f39a2d9c Add explicit support of OPL3-SA2 (YMF711).
Not well tested....

itohy 4283f00882 1. Change equalizer (treble, bass) to be ``flat'' if the values set at
the center position (128), so as to be compatible with other drivers.
    The equalizer is enhancement only, and the values < 128 don't take
    any effect.

    Yeah, this causes spec change....
    For equalization.treble and equalization.bass, the relation between
    old and new value is

	new_value = (old_value / 2) + 128.

    (Note this does not apply to equalization.surround.)

 2. Support ++ and -- of mixerctl(1) for stepping volume variables.

 3. Fix problem where the chip is not powered up
    when the mic input is unmuted.

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).

takemura 3c9d9276dc Add new powerhook argument values, PWR_SOFTSUSPEND, PWR_SOFTSTANDBY and
PWR_SOFTRESUME. Apm calls powerhook with the values in normal interrupt
priority level while others are protected with splhigh().

itohy 572e9e2f80 Move ym_mixer_set_port() (if used) during attach AFTER initialization of
power ctl stuff, or it makes unwanted changes to the CODEC settings.

augustss 8f0fb77674 MAke sure bass&treble start in their mid position. 2000-07-04 10:02:45 +00:00
thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

itohy 38e8851905 - Unmuting an external input source (CD playback, line input, and speaker)
now prevents power down/save the device.
  The external input sources are muted by default at initialization.
- Change "power.power.*" to "power.save.*".  Sorry, spec change....
- Shorten tsleep(9) ident string for "ps l".

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.

KNF.

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.
