| Hello All, I'm trying to write a driver for my Compro Videomate DVB-T220 card (It's a saa7134 based card). I have made a wiki page: http://www.linuxtv.org/wiki/index.php/Compro_VideoMate_DVB-T220 that contains the state of my card from the start. I have created a patch: IncompletePatchVideoMateT220.rtf that produces this output: dmesgOutput.rtf. Basically all the chipsets are identified, I just can't work out the right way to get them to work together. So I have a number of questions about my patch. Firstly, in the card configuration file, how do you determine the right vmux values to use for your inputs. At the moment I have just been attempting to purely guess. Second, my saa7134-dvb.c init and config functions are guesswork based on looking at what other similar cards do in here. Is there any insight as to what I need in here ? Finally, from the RegSpy dump on the wiki I can see changes to a few SAA7134 registers. Do I need to worry about integrating these into the driver somehow ? Thanks, Rob |
