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.

config THERMAL_HWMON
bool
prompt "Expose thermal sensors as hwmon device"
depends on HWMON=y || HWMON=THERMAL
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 THERMAL_OF
bool
prompt "APIs to parse thermal data out of device tree"
depends on OF
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.
choice
prompt "Default Thermal governor"
default THERMAL_DEFAULT_GOV_STEP_WISE
help
This option sets which thermal governor shall be loaded at
startup. If in doubt, select 'step_wise'.
config THERMAL_DEFAULT_GOV_STEP_WISE
bool "step_wise"
select THERMAL_GOV_STEP_WISE
help
Use the step_wise governor as default. This throttles the
devices one step at a time.
config THERMAL_DEFAULT_GOV_FAIR_SHARE
bool "fair_share"
select THERMAL_GOV_FAIR_SHARE
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 THERMAL_DEFAULT_GOV_USER_SPACE
bool "user_space"
select THERMAL_GOV_USER_SPACE
help
Select this if you want to let the user space manage the
platform thermals.
endchoice
config THERMAL_GOV_FAIR_SHARE
bool "Fair-share thermal governor"
help
Enable this to manage platform thermals using fair-share governor.
config THERMAL_GOV_STEP_WISE
bool "Step_wise thermal governor"
help
Enable this to manage platform thermals using a simple linear
governor.
config THERMAL_GOV_BANG_BANG
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).

bool "User_space thermal governor"
help
Enable this to let the user space manage the platform thermals.
config CPU_THERMAL
bool "generic cpu cooling support"
depends on CPU_FREQ
depends on THERMAL_OF
help
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.
If you want this support, you should say Y here.
config CLOCK_THERMAL
bool "Generic clock cooling support"
depends on COMMON_CLK
depends on PM_OPP
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.
If you want this support, you should say Y here.
config THERMAL_EMULATION
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.

depends on ARCH_U8500
depends on CPU_THERMAL
default y
help
Adds DB8500 cpufreq cooling devices, and these cooling devices can be
bound to thermal zone trip points. When a trip point reached, the
bound cpufreq cooling device turns active to set CPU frequency low to
cool down the CPU.
config INTEL_POWERCLAMP
tristate "Intel PowerClamp idle injection driver"
depends on THERMAL
depends on X86
depends on CPU_SUP_INTEL
help
Enable this to enable Intel PowerClamp idle injection driver. This
enforce idle time which results in more package C-state residency. The
user interface is exposed via generic thermal framework.
config X86_PKG_TEMP_THERMAL
tristate "X86 package temperature thermal driver"
depends on X86_THERMAL_VECTOR
select THERMAL_GOV_USER_SPACE

thermal zone. Each package will have its own thermal zone. There are
two trip points which can be set by user to get notifications via thermal
notification methods.
config INTEL_SOC_DTS_THERMAL
tristate "Intel SoCs DTS thermal driver"
depends on X86 && IOSF_MBI
help
Enable this to register Intel SoCs (e.g. Bay Trail) platform digital
temperature sensor (DTS). These SoCs have two additional DTSs in
addition to DTSs on CPU cores. Each DTS will be registered as a
thermal zone. There are two trip points. One of the trip point can
be set by user mode programs to get notifications via Linux thermal
notification methods.The other trip is a critical trip point, which
was set by the driver based on the TJ MAX temperature.
config INT340X_THERMAL
tristate "ACPI INT340X thermal drivers"
depends on X86 && ACPI
select THERMAL_GOV_USER_SPACE
select ACPI_THERMAL_REL
select ACPI_FAN
help
Newer laptops and tablets that use ACPI may have thermal sensors and
other devices with thermal control capabilities outside the core
CPU/SOC, for thermal safety reasons.
They are exposed for the OS to use via the INT3400 ACPI device object
as the master, and INT3401~INT340B ACPI device objects as the slaves.
Enable this to expose the temperature information and cooling ability
from these objects to userspace via the normal thermal framework.
This means that a wide range of applications and GUI widgets can show
the information to the user or use this information for making
decisions. For example, the Intel Thermal Daemon can use this
information to allow the user to select his laptop to run without
turning on the fans.
