==CMI8788 driver status==

Rewritten from scratch.
The second-most important feature, the MIDI port, now works.
(The most important feature, the colorful jack illumination on my Xonar card, is not controlled by software and has always worked.)<br><code>:-)</code>
should work:
*analog playback
**at 32, 44.1, 48, 64, 88.2, 96, 176.4, 192 kHz
**16 or 24 bits
**2, 4, 6, 8 channels
**volume controls for all eight channels
**upmixing of stereo to rear and side channels
*digital playback of PCM data (AC-3 not yet implemented)
currently untested:
*analog playback on cards with AK4396 DACs (i.e., any card except Xonar)
*analog recording
*digital recording
not yet implemented:
*front panel output
*mixer controls for analog recording
*controls for controlling SPDIF ports
known problems:
*some garbage at the beginning of recorded data → ADC needs more time to settle after clock switch

my TODO list

  1. lots of other things
  2. CMI8788 and Xonar drivers
  3. use hrtimers in the MIDI sequencer
    ca. 25%
  4. usb-audio: allow shorter-than-1ms periods for high-speed devices (just remove the code that rounds periods to USB frames)
    0%
  5. usb-audio: handle MIDI write errors better
  6. move non-public headers out of linux/include/sound/
  7. PCI: annotate in-memory data structures read by bus master chips with __le/be
  8. implement (some?) OSS 4 API ioctls
  9. test (i.e., use) alsa-python
  10. use dev_printk?
  11. various subsystem send different and too many MIDI reset commands when a port is closed
  12. usb-audio: restructure
  13. OSS emulation by redirecting to user space (like FUSE, but we need ioctls and mmap)
  14. MIDI synth: support more sysex commands
  15. MIDI synth: MIDI tuning
  16. ymfpci: MIDI synth
