^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) Once :ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` is called, the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) frontend will run a kernel thread that will periodically check for the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) tuner lock status and provide statistics about the quality of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) signal.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) The information about the frontend tuner locking status can be queried
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) using :ref:`FE_READ_STATUS`.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) Signal statistics are provided via

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22)    Most statistics require the demodulator to be fully locked
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23)    (e. g. with :c:type:`FE_HAS_LOCK <fe_status>` bit set). See
