Now I know that as I implement it. I added kthread and it works
correctly, just I though it is aimed to work. In my case signal strength
is reported by demod, not tuner, because there is some logic in firmware
to calculate it.
Here is patches you would like to look as a example:
af9033: implement DVBv5 statistic for signal strength
https://patchwork.linuxtv.org/patch/25748/
af9033: implement DVBv5 statistic for CNR
https://patchwork.linuxtv.org/patch/25744/
af9033: implement DVBv5 stat block counters
https://patchwork.linuxtv.org/patch/25749/
af9033: implement DVBv5 post-Viterbi BER
https://patchwork.linuxtv.org/patch/25750/
regards
Antti
