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

This implements the generic cpu cooling mechanism through frequency

reduction. An ACPI version of this already exists

(drivers/acpi/processor_thermal.c).

This will be useful for platforms using the generic thermal interface

and not the ACPI interface.

Enable this option to make a emul_temp sysfs node in thermal zone

user can manually input temperature and test the different trip

threshold behaviour for simulation purpose.

WARNING: Be careful while enabling this option on production systems,

because userland can easily disable the thermal policy by simply

flooding this sysfs node with low temperature values.
