There are a few things you can query:
1) the sensors list will have new things in it like gpsdo_locked, and
nmea strings:
http://files.ettus.com/uhd_docs/manual/html/gpsdo.html#using-the-gpsdo-in-your-application
2) The available time and clock sources list should also include gpsdo
(on the master branch)
Both of these things should be exposed in the python source/sink blocks.
