   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.

 175        help
 176          Newer laptops and tablets that use ACPI may have thermal sensors and
 177          other devices with thermal control capabilities outside the core
 178          CPU/SOC, for thermal safety reasons.
 179          They are exposed for the OS to use via the INT3400 ACPI device object
 180          as the master, and INT3401~INT340B ACPI device objects as the slaves.
 181          Enable this to expose the temperature information and cooling ability
 182          from these objects to userspace via the normal thermal framework.
 183          This means that a wide range of applications and GUI widgets can show
 184          the information to the user or use this information for making
 185          decisions. For example, the Intel Thermal Daemon can use this
 186          information to allow the user to select his laptop to run without
 187          turning on the fans.
