15 * Note #1 "Sek'd models" ................................... martin 2002-12-07
16 *
17 * Identical soundcards by Sek'd were labeled:
18 * RME Digi 32 = Sek'd Prodif 32
19 * RME Digi 32 Pro = Sek'd Prodif 96
20 * RME Digi 32/8 = Sek'd Prodif Gold

24 * Note #2 "full duplex mode" ............................... martin 2002-12-07
25 *
26 * Full duplex doesn't work. All cards (32, 32/8, 32Pro) are working identical
27 * in this mode. Rec data and play data are using the same buffer therefore. At
28 * first you have got the playing bits in the buffer and then (after playing
29 * them) they were overwitten by the captured sound of the CS8412/14. Both
30 * modes (play/record) are running harmonically hand in hand in the same buffer
31 * and you have only one start bit plus one interrupt bit to control this
32 * paired action.
33 * This is opposite to the latter rme96 where playing and capturing is totally
34 * separated and so their full duplex mode is supported by alsa (using two
35 * start bits and two interrupts for two different buffers).
36 * But due to the wrong sequence of playing and capturing ALSA shows no solved
37 * full duplex support for the rme32 at the moment. That's bad, but I'm not
38 * able to solve it. Are you motivated enough to solve this problem now? Your
39 * patch would be welcome!
40 *
41 * ****************************************************************************
42 *
43 * "The story after the long seeking" -- tiwai
44 *
45 * Ok, the situation regarding the full duplex is now improved a bit.
46 * In the fullduplex mode (given by the module parameter), the hardware buffer
47 * is split to halves for read and write directions at the DMA pointer.
48 * That is, the half above the current DMA pointer is used for write, and
49 * the half below is used for read. To mangle this strange behavior, an
50 * software intermediate buffer is introduced. This is, of course, not good
51 * from the viewpoint of the data transfer efficiency. However, this allows
52 * you to use arbitrary buffer sizes, instead of the fixed I/O buffer size.
