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 .
