ATC notified us when we checked in; that GPS jamming was taking place. we received an ATC fail; and eventually GPS caution.  We lost both the left and right GPS.  They never came back; until we were on the ground and Maintenance reset the circuit breakers. I've seen GPS jamming before; but I've never seen that the GPS; and transponder didn't come back.
Air carrier Captain reported GPS jamming as probable cause of GPS navigation and transponder failure; instead of temporary interference.
