The Apalis TK1 datasheet (p. 67) states that thermal throttling (DVFS) is supported for the CPU, GPU and the core voltage. I found out where to configure the thermal zones. However I do not know how they are linked to the cooling devices and how to configure the cooling devices appropriately. Where do I find information about how to configure the different throttlings?
/sys/class/thermal/ thermal_zone0/ available_policies (pid_thermal_gov step_wise) policy (e.g. pid_thermal_gov) trip_point_0_temp (e.g. 105000) trip_point_0_type (e.g. critical) ... ... cooling_device0/ type (e.g. cpu_edp)
