# # Generic thermal sysfs drivers configuration # menuconfig THERMAL 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. if THERMAL 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). config THERMAL_GOV_USER_SPACE 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 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. config IMX_THERMAL tristate "Temperature sensor driver for Freescale i.MX SoCs" depends on CPU_THERMAL depends on MFD_SYSCON depends on OF help Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs. It supports one critical trip point and one passive trip point. The cpufreq is used as the cooling device to throttle CPUs when the passive trip is crossed. config SPEAR_THERMAL bool "SPEAr thermal sensor driver" depends on PLAT_SPEAR depends on OF help Enable this to plug the SPEAr thermal sensor driver into the Linux thermal framework. config RCAR_THERMAL tristate "Renesas R-Car thermal driver" depends on ARCH_SHMOBILE || COMPILE_TEST depends on HAS_IOMEM help Enable this to plug the R-Car thermal sensor driver into the Linux thermal framework. config KIRKWOOD_THERMAL tristate "Temperature sensor on Marvell Kirkwood SoCs" depends on MACH_KIRKWOOD depends on OF help Support for the Kirkwood thermal sensor driver into the Linux thermal framework. Only kirkwood 88F6282 and 88F6283 have this sensor. config DOVE_THERMAL tristate "Temperature sensor on Marvell Dove SoCs" depends on ARCH_DOVE || MACH_DOVE depends on OF help Support for the Dove thermal sensor driver in the Linux thermal framework. config DB8500_THERMAL bool "DB8500 thermal management" depends on ARCH_U8500 default y help Adds DB8500 thermal management implementation according to the thermal management framework. A thermal zone with several trip points will be created. Cooling devices can be bound to the trip points to cool this thermal zone if trip points reached. config ARMADA_THERMAL tristate "Armada 370/XP thermal management" depends on ARCH_MVEBU depends on OF help Enable this option if you want to have support for thermal management controller present in Armada 370 and Armada XP SoC. config DB8500_CPUFREQ_COOLING tristate "DB8500 cpufreq cooling" 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 default m help Enable this to register CPU digital sensor for package temperature as 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. config ACPI_THERMAL_REL tristate depends on ACPI menu "Texas Instruments thermal drivers" source "drivers/thermal/ti-soc-thermal/Kconfig" endmenu menu "Samsung thermal drivers" depends on ARCH_EXYNOS source "drivers/thermal/samsung/Kconfig" endmenu menu "STMicroelectronics thermal drivers" depends on ARCH_STI && OF source "drivers/thermal/st/Kconfig" endmenu endif
