Once FE_SET_PROPERTY
is called, the frontend will run a kernel thread that will periodically
check for the tuner lock status and provide statistics about the quality
of the signal.
The information about the frontend tuner locking status can be queried using FE_READ_STATUS.
Signal statistics are provided via FE_GET_PROPERTY
.
Please note that several statistics require the demodulator to be fully
locked (e. g. with FE_HAS_LOCK bit set). See
Frontend statistics indicators
for more details.
