18 Vortex core low level functions.
19
20 Author: Manuel Jander (mjander@users.sourceforge.cl)
21 These functions are mainly the result of translations made
22 from the original disassembly of the au88x0 binary drivers,
23 written by Aureal before they went down.
24 Many thanks to the Jeff Muizelaar, Kester Maddock, and whoever
25 contributed to the OpenVortex project.
26 The author of this file, put the few available pieces together
27 and translated the rest of the riddle (Mix, Src and connection stuff).
28 Some things are still to be discovered, and their meanings are unclear.
29
30 Some of these functions aren't intended to be really used, rather
31 to help to understand how does the AU88X0 chips work. Keep them in, because
32 they could be used somewhere in the future.
33
34 This code hasn't been tested or proof read thoroughly. If you wanna help,
35 take a look at the AU88X0 assembly and check if this matches.
36 Functions tested ok so far are (they show the desired effect
37 at least):
38 vortex_routes(); (1 bug fixed).
39 vortex_adb_addroute();
40 vortex_adb_addroutes();
41 vortex_connect_codecplay();
42 vortex_src_flushbuffers();
43 vortex_adbdma_setmode(); note: still some unknown arguments!
44 vortex_adbdma_startfifo();
45 vortex_adbdma_stopfifo();
46 vortex_fifo_setadbctrl(); note: still some unknown arguments!
47 vortex_mix_setinputvolumebyte();
48 vortex_mix_enableinput();
49 vortex_mixer_addWTD(); (fixed)
50 vortex_connection_adbdma_src_src();
51 vortex_connection_adbdma_src();
52 vortex_src_change_convratio();
53 vortex_src_addWTD(); (fixed)

55 History:
56
57 01-03-2003 First revision.
58 01-21-2003 Some bug fixes.
59 17-02-2003 many bugfixes after a big versioning mess.
60 18-02-2003 JAAAAAHHHUUUUUU!!!! The mixer works !! I'm just so happy !
61 (2 hours later...) I cant believe it! Im really lucky today.
62 Now the SRC is working too! Yeah! XMMS works !
63 20-02-2003 First steps into the ALSA world.
64 28-02-2003 As my birthday present, i discovered how the DMA buffer pages really
65 work :-). It was all wrong.
66 12-03-2003 ALSA driver starts working (2 channels).
67 16-03-2003 More srcblock_setupchannel discoveries.
68 12-04-2003 AU8830 playback support. Recording in the works.
69 17-04-2003 vortex_route() and vortex_routes() bug fixes. AU8830 recording
70 works now, but chipn' dale effect is still there.
71 16-05-2003 SrcSetupChannel cleanup. Moved the Src setup stuff entirely
72 into au88x0_pcm.c .
73 06-06-2003 Buffer shifter bugfix. Mixer volume fix.
74 07-12-2003 A3D routing finally fixed. Believed to be OK.
75 25-03-2004 Many thanks to Claudia, for such valuable bug reports.
