   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.

  74          This implements the generic cpu cooling mechanism through frequency
  75          reduction. An ACPI version of this already exists
  76          (drivers/acpi/processor_thermal.c).
  77          This will be useful for platforms using the generic thermal interface
  78          and not the ACPI interface.

  86          directory to support temperature emulation. With emulation sysfs node,
  87          user can manually input temperature and test the different trip
  88          threshold behaviour for simulation purpose.

  90          WARNING: Be careful while enabling this option on production systems,
  91          because userland can easily disable the thermal policy by simply
  92          flooding this sysfs node with low temperature values.
