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

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