mycroft 81d2718d5b Add support for polling. 1999-03-18 06:03:31 +00:00
mycroft 3e404912dc Clean up the previous:
* Separate the interrupt handlers based on which channel (audio1/audio2)
  rather than which direction (input/output).  Only register the handler for
  audio1 on the 1788.
* Since the input sides are actually the same, GC the duplicated code.
* Re-KNF in a bunch of places.
* Make this work again on the 1887 in the Shark.

nathanw 64fffdfef9 Add support for the 1788 AudioDrive chip.
Some minor cleanup; refer to more registers by macros rather
than raw hex constants.

matthias 1f5c14d8ef ess_audio_channel:active is now used even when DIAGNOSTICS is not defined. 1998-08-11 12:16:22 +00:00
matt 8ba8e2056b Remove unused field (sc_ih) in ess_softc (interrupt handlers are kept
in a per-direction structure).

mycroft 7fca135b1b Use the new trigger interface. 1998-08-10 15:32:18 +00:00
mycroft 0611fc34f8 Don't actually touch the hardware in set_params; defer that until we actually
start a transfer.  Instead, just check that the parameters are valid.
Also, use 16-bit output for u-law and a-law.

mycroft c8532af3b2 Make sure the sample rate is the same on both channels, tracking the change
from one channel to the other if only one is active.

augustss f76fb48283 Use looping DMA for play channel.
More cleanup.

augustss 6b407a79c6 Major cleanup of the ESS driver. It now sorta works. More to come. 1998-07-31 15:17:17 +00:00
augustss cdeb158d5f A first stab at making the SHARK sound work. It doesn't really work
yet, but it probes and makes a noise when used.  Stay tuned!

augustss 080dc567e8 A first stab at an ESS1887 driver. The code is from the SHARK port
and needs a lot of polishing.  The code compiles (on i386), but is
untested.  See ess.c for a TODO list.
