| bool "Thermal drivers" |
| help |
| Thermal drivers offer a generic mechanism for |
| thermal management. Usually it's made up of one or more thermal |
| zones and cooling devices. |
| Each thermal zone contains its own temperature, trip points, |
| and cooling devices. |
| All platforms with ACPI or Open Firmware thermal support can use |
| this driver. |
| If you want this support, you should say Y here. |
| |
| if THERMAL |
| |
| config THERMAL_NETLINK |
| bool "Thermal netlink management" |
| depends on NET |
| help |
| The thermal framework has a netlink interface to do thermal |
| zones discovery, temperature readings and events such as |
| trip point crossed, cooling device update or governor |
| change. It is recommended to enable the feature. |
| |
| config THERMAL_STATISTICS |
| bool "Thermal state transition statistics" |
| help |
| Export thermal state transition statistics information through sysfs. |
| |
| If in doubt, say N. |
| |
| config THERMAL_DEBUGFS |
| bool "Thermal subsystem debug support" |
| depends on DEBUG_FS |
| help |
| Say Y to allow the thermal subsystem to collect diagnostic |
| information that can be accessed via debugfs. |
| |
| config THERMAL_EMERGENCY_POWEROFF_DELAY_MS |
| 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 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. |

| 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 |
| The Userspace governor allows to get trip point crossed |
| notification from the kernel via uevents. It is recommended |
| to use the netlink interface instead which gives richer |
| information about the thermal framework events. |
| |
| config THERMAL_DEFAULT_GOV_POWER_ALLOCATOR |
| bool "power_allocator" |
| depends on THERMAL_GOV_POWER_ALLOCATOR |
| 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. |
| |
| config THERMAL_DEFAULT_GOV_BANG_BANG |
| bool "bang_bang" |
| depends on THERMAL_GOV_BANG_BANG |
| help |
| Use the bang_bang governor as default. This throttles the |
| devices one step at the time, taking into account the trip |
| point hysteresis. |

| 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 THERMAL_GOV_USER_SPACE |
| bool "User_space thermal governor" |

| config CPU_FREQ_THERMAL |
| bool "CPU frequency cooling device" |
| depends on CPU_FREQ |
| default y |
| 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. |
| |
| config CPU_IDLE_THERMAL |
| bool "CPU idle cooling device" |
| depends on IDLE_INJECT |
| help |
| This implements the CPU cooling mechanism through |
| idle injection. This will throttle the CPU by injecting |
| idle cycle. |

| config DEVFREQ_THERMAL |
| bool "Generic device cooling support" |
| depends on PM_DEVFREQ |
| depends on PM_OPP |
| 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 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. |

| driver. |
