Customize a thermal zone

The thermal zone connects the Tsens hardware information, temperature thresholds, and mitigation actions. The thermal framework creates node IDs for each thermal zone rule defined in the device tree. The following table lists the sysfs commands used to read and customize the thermal zone configurations: Note <x> in the table represents thermal zone ID. Table : Description of thermal zone commands

Commands	Description
ls /sys/class/thermal/thermal_zone*	Lists all thermal zones and their IDs that the device contains
cat /sys/class/thermal/thermal_zone<x>/type	cat /sys/class/thermal/thermal_zone<x>/type
echo enabled > /sys/class/thermal/thermal_zone<x>/mode	Enables a thermal zone Note All thermal zones are enabled by default.
echo disabled > /sys/class/thermal/thermal_zone<x>/mode	Disables a thermal zone
echo <trip_temp> >/sys/class/thermal/thermal_zone<x>/trip_point_<A>_temp Here, `trip_temp` is the temperature threshold in m°C. `A` denotes trip point numerical. For example, you can modify the temperature threshold for a trip point 0 using the following command: echo 95000 > /sys/class/thermal/thermal_zone20/trip_point_0_temp	Modifies the threshold temperature for trip point A Verify the number of trip points available to the thermal zone in the thermal zone directory and run the command: > `text > /sys/class/thermal/thermal_zone<x> >`

Note Modifications to the temperature threshold configurations should be for test purpose only. Don’t change any thermal zone configurations of Tsens. Resetting the device changes modifications performed through sysfs commands to default values. You can add a product specific thermal zone and its rules in the device tree to control the temperature of the device according to the thermal requirement as described in: Configure a thermal zone.
