We test AndroidKK4.4.3 in MX6Q_SABRE-SDB
When CPU load increases, case temperature repeats 92 degrees Celsius and 82 degrees Celsius.
I understand that AndroidKK4.4.3 has Thermal driver.
I referred to the following. Each parameter was as follows.
(I used a cat command.)
temp ===> 34918
trip_point_0_temp ===> 85000
trip_point_0_type ===> passive
trip_point_1_temp ===> 100000
trip_point_1_type ===> critical
I understand that frequency of CPU and GPU are decreased when the temperature of the CPU reached 85 degrees Celsius.
I was able to change a value of trip_point_0_temp by using echo command.
echo 90000 > /sys/devices/virtual/thermal/thermal_zone0/trip_point_0_temp
However, I do not understand the change method of the frequency value of CPU and GPU.
Would you tell me the method to set the decreased the frequency of CPU and GPU?
