  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.

 99           (drivers/acpi/processor_thermal.c).
100           This will be useful for platforms using the generic thermal interface

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

214           Newer laptops and tablets that use ACPI may have thermal sensors
215           outside the core CPU/SOC for thermal safety reasons. These
216           temperature sensors are also exposed for the OS to use via the so
217           called INT3403 ACPI object. This driver will, on devices that have
218           such sensors, expose the temperature information from these sensors
219           to userspace via the normal thermal framework. This means that a wide
220           range of applications and GUI widgets can show this information to
221           the user or use this information for making decisions. For example,
222           the Intel Thermal Daemon can use this information to allow the user
