menuconfig [31mCONFIG_THERMAL[0m
bool "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 [31mCONFIG_ACPI[0m thermal support can use this driver.
If you want this support, you should say Y here.
if [31mCONFIG_THERMAL[0m
config [31mCONFIG_THERMAL_STATISTICS[0m
bool "Thermal state transition statistics"
help
Export thermal state transition statistics information through sysfs.
If in doubt, say N.
config [31mCONFIG_THERMAL_EMERGENCY_POWEROFF_DELAY_MS[0m
int "Emergency poweroff delay in milli-seconds"
default 0
help
Thermal subsystem will issue a graceful shutdown when
critical temperatures are reached using orderly_poweroff(). In
case of failure of an orderly_poweroff(), the thermal emergency
poweroff kicks in after a delay has elapsed and shuts down the system.
This config is number of milliseconds to delay before emergency
poweroff kicks in. Similarly to the critical trip point,
the delay should be carefully profiled so as to give adequate
time for orderly_poweroff() to finish on regular execution.
If set to 0 emergency poweroff will not be supported.
In doubt, leave as 0.
config [31mCONFIG_THERMAL_HWMON[0m
bool
prompt "Expose thermal sensors as hwmon device"
depends on [31mCONFIG_HWMON[0m=y || [31mCONFIG_HWMON[0m=[31mCONFIG_THERMAL[0m
default y
help
In case a sensor is registered with the thermal
framework, this option will also register it
as a hwmon. The sensor will then have the common
hwmon sysfs interface.
Say 'Y' here if you want all thermal sensors to
have hwmon sysfs interface too.
config [31mCONFIG_THERMAL_OF[0m
bool
prompt "APIs to parse thermal data out of device tree"
depends on [31mCONFIG_OF[0m
default y
help
This options provides helpers to add the support to
read and parse thermal data definitions out of the
device tree blob.
Say 'Y' here if you need to build thermal infrastructure
based on device tree.
config [31mCONFIG_THERMAL_WRITABLE_TRIPS[0m
bool "Enable writable trip points"
help
This option allows the system integrator to choose whether
trip temperatures can be changed from userspace. The
writable trips need to be specified when setting up the
thermal zone but the choice here takes precedence.
Say 'Y' here if you would like to allow userspace tools to
change trip temperatures.

prompt "Default Thermal governor"
default [31mCONFIG_THERMAL_DEFAULT_GOV_STEP_WISE[0m

This option sets which thermal governor shall be loaded at
startup. If in doubt, select 'step_wise'.

bool "step_wise"
select [31mCONFIG_THERMAL_GOV_STEP_WISE[0m
help
Use the step_wise governor as default. This throttles the
devices one step at a time.
config [31mCONFIG_THERMAL_DEFAULT_GOV_FAIR_SHARE[0m
bool "fair_share"
select [31mCONFIG_THERMAL_GOV_FAIR_SHARE[0m
help
Use the fair_share governor as default. This throttles the
devices based on their 'contribution' to a zone. The
contribution should be provided through platform data.
config [31mCONFIG_THERMAL_DEFAULT_GOV_USER_SPACE[0m
bool "user_space"
select [31mCONFIG_THERMAL_GOV_USER_SPACE[0m
help
Select this if you want to let the user space manage the
platform thermals.
config [31mCONFIG_THERMAL_DEFAULT_GOV_POWER_ALLOCATOR[0m
bool "power_allocator"
select [31mCONFIG_THERMAL_GOV_POWER_ALLOCATOR[0m
help
Select this if you want to control temperature based on
system and device power allocation. This governor can only
operate on cooling devices that implement the power API.

governor.

bool "Bang Bang thermal governor"
default n
help
Enable this to manage platform thermals using bang bang governor.
Say 'Y' here if you want to use two point temperature regulation
used for fans without throttling. Some fan drivers depend on this
governor to be enabled (e.g. acerhdf).
config [31mCONFIG_THERMAL_GOV_USER_SPACE[0m
bool "User_space thermal governor"
help
Enable this to let the user space manage the platform thermals.

allocating and limiting power to devices.
config [31mCONFIG_CPU_THERMAL[0m
bool "Generic cpu cooling support"
depends on [31mCONFIG_CPU_FREQ[0m
depends on [31mCONFIG_THERMAL_OF[0m
help
This implements the generic cpu cooling mechanism through frequency
reduction. An [31mCONFIG_ACPI[0m version of this already exists
(drivers/acpi/processor_thermal.c).
This will be useful for platforms using the generic thermal interface
and not the [31mCONFIG_ACPI[0m interface.
If you want this support, you should say Y here.
config [31mCONFIG_CLOCK_THERMAL[0m
bool "Generic clock cooling support"
depends on [31mCONFIG_COMMON_CLK[0m
depends on [31mCONFIG_PM_OPP[0m
help
This entry implements the generic clock cooling mechanism through
frequency clipping. Typically used to cool off co-processors. The
device that is configured to use this cooling mechanism will be
controlled to reduce clock frequency whenever temperature is high.
config [31mCONFIG_DEVFREQ_THERMAL[0m
bool "Generic device cooling support"
depends on [31mCONFIG_PM_DEVFREQ[0m
depends on [31mCONFIG_PM_OPP[0m
help
This implements the generic devfreq cooling mechanism through
frequency reduction for devices using devfreq.
This will throttle the device by limiting the maximum allowed DVFS
frequency corresponding to the cooling level.
In order to use the power extensions of the cooling device,
devfreq should use the simple_ondemand governor.
If you want this support, you should say Y here.
config [31mCONFIG_THERMAL_EMULATION[0m
bool "Thermal emulation mode support"
help
Enable this option to make a emul_temp sysfs node in thermal zone
directory to support temperature emulation. With emulation sysfs node,
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.

This option enables the generic thermal MMIO driver that will use
memory-mapped reads to get the temperature. Any HW/System that
allows temperature reading by a single memory-mapped reading, be it
register or shared memory, is a potential candidate to work with this
driver.
