As updating an LNA (or something else) is very board specific, I put callback "update_lna" in dib3000mc_config. I will call this after starting the AGCs to see if the LNA has to be turned on or not (taking the agc response into account). For that I would like to know, what is the gain of the LNA when turned on? (So that I can adjust the thresholds when to turn on or off). Maybe we need to make an average of both channels, not that we kill one channel by only taking the other one into account. Or is a module_parameter enough? (I don't like this, because the majority of users does not even now what is a module, which is good). best regards, Patrick. -- Mail: patrick.boettcher@xxxxxxx WWW: http://www.wi-bw.tfh-wildau.de/~pboettch/ _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
