Currently, we have three Kconfig options for thermal governors, aka, CONFIG_FAIR_SHARE, CONFIG_USER_SPACE and CONFIG_STEP_WISE. But these names are too generic that may bring confusion to users. Rename them to CONFIG_THERMAL_GOV_FAIR_SHARE, CONFIG_THERMAL_GOV_USER_SPACE, CONFIG_THERMAL_GOV_STEP_WISE to avoid the generic naming. Signed-off-by: Zhang Rui <rui.zhang@intel.com>

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, cpu hotplug and any other ways of reducing temperature. 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.
