5752a55af4 Zap drq2 if unused. 1997-08-28 00:02:12 +00:00

a50d4ba893 XXX Add a drq2 locator for the ISA bus. Many sound cards need
two DMA channels to do e.g. full-duplex.  This allows
a way of specifying the second channel in a sane way.
THIS IS TEMPORARY.  The drq2 locator will go away when
the locator system has been changed to allow multiple
values per locator.

3bcc377a4c Implement a function to test if a drq is taken and use it
in two drivers.  There are still many drivers left to fix...

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.

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.
