  7         help
  8           Generic Thermal Sysfs driver offers a generic mechanism for
  9           thermal management. Usually it's made up of one or more thermal
 10           zone and cooling device.
 11           Each thermal zone contains its own temperature, trip points,
 12           cooling devices.
 13           All platforms with ACPI thermal support can use this driver.
 14           If you want this support, you should say Y or M here.

 24           In case a sensor is registered with the thermal
 25           framework, this option will also register it
 26           as a hwmon. The sensor will then have the common
 27           hwmon sysfs interface.
 28 
 29           Say 'Y' here if you want all thermal sensors to
 30           have hwmon sysfs interface too.

135           WARNING: Be careful while enabling this option on production systems,
136           because userland can easily disable the thermal policy by simply
