Usually it's made up of one or more thermal 10 zone and cooling device. 11 Each thermal zone contains its own temperature, trip points, 12 cooling devices. 13 All platforms with ACPI thermal support can use this driver. 14 If you want this support, you should say Y or M here. 15 16if THERMAL 17 18config THERMAL_HWMON 19 bool 20 prompt "Expose thermal sensors as hwmon device" 21 depends on HWMON=y || HWMON=THERMAL 22 default y 23 help 24 In case a sensor is registered with the thermal 25 framework, this option will also register it 26 as a hwmon. The sensor will then have the common 27 hwmon sysfs interface. 28 29 Say 'Y' here if you want all thermal sensors to 30 have hwmon sysfs interface too. 31 32config THERMAL_OF 33 bool 34 prompt "APIs to parse thermal data out of device tree" 35 depends on OF 36 default y 37 help 38 This options provides helpers to add the support to 39 read and parse thermal data definitions out of the 40 device tree blob. 41 42 Say 'Y' here if you need to build thermal infrastructure 43 based on device tree. 44 45choice 46 prompt "Default Thermal governor" 47 default THERMAL_DEFAULT_GOV_STEP_WISE 48 help 49 This option sets which thermal governor shall be loaded at 50 startup. If in doubt, select 'step_wise'. 51 52config THERMAL_DEFAULT_GOV_STEP_WISE 53 bool "step_wise" 54 select THERMAL_GOV_STEP_WISE 55 help 56 Use the step_wise governor as default. This throttles the 57 devices one step at a time. 58 59config THERMAL_DEFAULT_GOV_FAIR_SHARE 60 bool "fair_share" 61 select THERMAL_GOV_FAIR_SHARE 62 help 63 Use the fair_share governor as default. This throttles the 64 devices based on their 'contribution' to a zone. The 65 contribution should be provided through platform data. 66 67config THERMAL_DEFAULT_GOV_USER_SPACE 68 bool "user_space" 69 select THERMAL_GOV_USER_SPACE 70 help 71 Select this if you want to let the user space manage the 72 platform thermals. 73 74endchoice 75 76config THERMAL_GOV_FAIR_SHARE 77 bool "Fair-share thermal governor" 78 help 79 Enable this to manage platform thermals using fair-share governor. 80 81config THERMAL_GOV_STEP_WISE 82 bool "Step_wise thermal governor" 83 help 84 Enable this to manage platform thermals using a simple linear 85 governor. 86 87config THERMAL_GOV_USER_SPACE 88 bool "User_space thermal governor" 89 help 90 Enable this to let the user space manage the platform thermals. 91 92config CPU_THERMAL 93 bool "generic cpu cooling support" 94 depends on CPU_FREQ 95 depends on THERMAL_OF 96 help 97 This implements the generic cpu cooling mechanism through frequency 98 reduction. An ACPI version of this already exists 99 (drivers/acpi/processor_thermal.c). 100 This will be useful for platforms using the generic thermal interface 101 and not the ACPI interface. 102 103 If you want this support, you should say Y here. 104 105config THERMAL_EMULATION 106 bool "Thermal emulation mode support" 107 help 108 Enable this option to make a emul_temp sysfs node in thermal zone 109 directory to support temperature emulation. With emulation sysfs node, 110 user can manually input temperature and test the different trip 111 threshold behaviour for simulation purpose. 112 113 WARNING: Be careful while enabling this option on production systems, 114 because userland can easily disable the thermal policy by simply 115 flooding this sysfs node with low temperature values. 116 117config IMX_THERMAL 118 tristate "Temperature sensor driver for Freescale i.MX SoCs" 119 depends on CPU_THERMAL 120 depends on MFD_SYSCON 121 depends on OF 122 help 123 Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs. 124 It supports one critical trip point and one passive trip point. The 125 cpufreq is used as the cooling device to throttle CPUs when the 126 passive trip is crossed. 127 128config SPEAR_THERMAL 129 bool "SPEAr thermal sensor driver" 130 depends on PLAT_SPEAR 131 depends on OF 132 help 133 Enable this to plug the SPEAr thermal sensor driver into the Linux 134 thermal framework. 135 136config RCAR_THERMAL 137 tristate "Renesas R-Car thermal driver" 138 depends on ARCH_SHMOBILE || COMPILE_TEST 139 depends on HAS_IOMEM 140 help 141 Enable this to plug the R-Car thermal sensor driver into the Linux 142 thermal framework. 143 144config KIRKWOOD_THERMAL 145 tristate "Temperature sensor on Marvell Kirkwood SoCs" 146 depends on ARCH_KIRKWOOD || MACH_KIRKWOOD 147 depends on OF 148 help 149 Support for the Kirkwood thermal sensor driver into the Linux thermal 150 framework.

A thermal zone with several trip points will be 167 created. Cooling devices can be bound to the trip points to cool this 168 thermal zone if trip points reached. 169 170config ARMADA_THERMAL 171 tristate "Armada 370/XP thermal management" 172 depends on ARCH_MVEBU 173 depends on OF 174 help 175 Enable this option if you want to have support for thermal management 176 controller present in Armada 370 and Armada XP SoC. 177 178config DB8500_CPUFREQ_COOLING 179 tristate "DB8500 cpufreq cooling" 180 depends on ARCH_U8500 181 depends on CPU_THERMAL 182 default y 183 help 184 Adds DB8500 cpufreq cooling devices, and these cooling devices can be 185 bound to thermal zone trip points. When a trip point reached, the 186 bound cpufreq cooling device turns active to set CPU frequency low to 187 cool down the CPU. 188 189config INTEL_POWERCLAMP 190 tristate "Intel PowerClamp idle injection driver" 191 depends on THERMAL 192 depends on X86 193 depends on CPU_SUP_INTEL 194 help 195 Enable this to enable Intel PowerClamp idle injection driver. This 196 enforce idle time which results in more package C-state residency.

Each package will have its own thermal zone. There are 207 two trip points which can be set by user to get notifications via thermal 208 notification methods. 209 210config ACPI_INT3403_THERMAL 211 tristate "ACPI INT3403 thermal driver" 212 depends on X86 && ACPI 213 help 214 Newer laptops and tablets that use ACPI may have thermal sensors 215 outside the core CPU/SOC for thermal safety reasons. These 216 temperature sensors are also exposed for the OS to use via the so 217 called INT3403 ACPI object. This driver will, on devices that have 218 such sensors, expose the temperature information from these sensors 219 to userspace via the normal thermal framework. This means that a wide 220 range of applications and GUI widgets can show this information to 221 the user or use this information for making decisions. For example, 222 the Intel Thermal Daemon can use this information to allow the user 223 to select his laptop to run without turning on the fans. 224 225config INTEL_SOC_DTS_THERMAL 226 tristate "Intel SoCs DTS thermal driver" 227 depends on X86 && IOSF_MBI 228 help 229 Enable this to register Intel SoCs (e.g. Bay Trail) platform digital 230 temperature sensor (DTS). These SoCs have two additional DTSs in 231 addition to DTSs on CPU cores. Each DTS will be registered as a 232 thermal zone. There are two trip points. One of the trip point can 233 be set by user mode programs to get notifications via Linux thermal 234 notification methods.The other trip is a critical trip point, which 235 was set by the driver based on the TJ MAX temperature. 236 237menu "Texas Instruments thermal drivers" 238source "drivers/thermal/ti-soc-thermal/Kconfig" 239endmenu 240 241menu "Samsung thermal drivers" 242depends on ARCH_EXYNOS 243source "drivers/thermal/samsung/Kconfig" 244endmenu 245 246endif 247
