I have two questions regarding thermal zones (/sys/devices/virtual/thermal/thermal_zone?):
The thermal zone GPU-therm has 7 trip points. The cooling device of the first five zones is tegra-eqos (the next one is a critical so no cooling device and the last one is passive so gpu-balancing). Questions: What is ‘tegra-eqos’ for a cooling device? What does it do?
I understand the Thermal-fan-est zone (thermal_zone7) so that this zone is to control the fan in respect to the temperature. Questions is what sensor is used to measure this temperature (where does the content of /sys/devices/virtual/thermal/thermal_zone7/temp comes from)?
