I will try to review it on Monday... I looked quickly your old patch last week and tuner driver was done by Hans-Frieder Vogt. I think he should send tuner patch first and then your rtl2832 applied top of that. > As I don't own a device with a different tuner than the fc0012 I will > include an error message about the unsupported tuner and print its > type.

But that estimation is very poor, tuner could report it more accurate. On optimal situation you should implement demod callback for signal strength and if there is tuner callback then override demod callback in order to get better reports. IMHO that override should be done in DVB-USB driver, in that case dvb-usb-rtl2832u. So when you attach rtl2832u just after that override demod callback with tuner. regards Antti -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
