moikka,
Start polling thread, which polls once per 2 sec or so, which reads RSSI
and writes value to struct dtv_frontend_properties. That it is, in my
understanding. Same for all those DVBv5 stats. Mauro knows better as he
designed that functionality.
I understand that RSSI property should be set directly in the tuner driver,
but I'm afraid that creating a kthread just for updating RSSI would be
overkill and complicate matters.
Would you give me an advice? >> Mauro
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/

Antti
