Unlike the CPU, the CDSP does not throttle its speed automatically when it reaches high temperatures in monaco. Set up CDSP cooling by throttling the cdsp, when it reaches 115°C. Add polling-delay-passive so the governor periodically evaluates the zone during passive cooling and steps up cooling levels when temperature stabilizes below the next trip.
