29 * Note #1 "Sek'd models" ................................... martin 2002-12-07
30 *
31 * Identical soundcards by Sek'd were labeled:
32 * RME Digi 32 = Sek'd Prodif 32
33 * RME Digi 32 Pro = Sek'd Prodif 96
34 * RME Digi 32/8 = Sek'd Prodif Gold

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.
67 *
