  38  * Note #2 "full duplex mode" ............................... martin 2002-12-07
  39  *
  40  * Full duplex doesn't work. All cards (32, 32/8, 32Pro) are working identical
  41  * in this mode. Rec data and play data are using the same buffer therefore. At
  42  * first you have got the playing bits in the buffer and then (after playing
  43  * them) they were overwitten by the captured sound of the CS8412/14. Both
  44  * modes (play/record) are running harmonically hand in hand in the same buffer
  45  * and you have only one start bit plus one interrupt bit to control this
  46  * paired action.
  47  * This is opposite to the latter rme96 where playing and capturing is totally
  48  * separated and so their full duplex mode is supported by alsa (using two
  49  * start bits and two interrupts for two different buffers).
  50  * But due to the wrong sequence of playing and capturing ALSA shows no solved
  51  * full duplex support for the rme32 at the moment. That's bad, but I'm not
  52  * able to solve it. Are you motivated enough to solve this problem now? Your
  53  * patch would be welcome!
  54  *
  55  * ****************************************************************************
  56  *
  57  * "The story after the long seeking" -- tiwai
  58  *
  59  * Ok, the situation regarding the full duplex is now improved a bit.
  60  * In the fullduplex mode (given by the module parameter), the hardware buffer
  61  * is split to halves for read and write directions at the DMA pointer.
  62  * That is, the half above the current DMA pointer is used for write, and
  63  * the half below is used for read.  To mangle this strange behavior, an
  64  * software intermediate buffer is introduced.  This is, of course, not good
  65  * from the viewpoint of the data transfer efficiency.  However, this allows
  66  * you to use arbitrary buffer sizes, instead of the fixed I/O buffer size.
