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 32choice 33 prompt "Default Thermal governor" 34 default THERMAL_DEFAULT_GOV_STEP_WISE 35 help 36 This option sets which thermal governor shall be loaded at 37 startup. If in doubt, select 'step_wise'. 38 39config THERMAL_DEFAULT_GOV_STEP_WISE 40 bool "step_wise" 41 select THERMAL_GOV_STEP_WISE 42 help 43 Use the step_wise governor as default. This throttles the 44 devices one step at a time. 45 46config THERMAL_DEFAULT_GOV_FAIR_SHARE 47 bool "fair_share" 48 select THERMAL_GOV_FAIR_SHARE 49 help 50 Use the fair_share governor as default. This throttles the 51 devices based on their 'contribution' to a zone. The 52 contribution should be provided through platform data. 53 54config THERMAL_DEFAULT_GOV_USER_SPACE 55 bool "user_space" 56 select THERMAL_GOV_USER_SPACE 57 help 58 Select this if you want to let the user space manage the 59 platform thermals. 60 61endchoice 62 63config THERMAL_GOV_FAIR_SHARE 64 bool "Fair-share thermal governor" 65 help 66 Enable this to manage platform thermals using fair-share governor. 67 68config THERMAL_GOV_STEP_WISE 69 bool "Step_wise thermal governor" 70 help 71 Enable this to manage platform thermals using a simple linear 72 governor. 73 74config THERMAL_GOV_USER_SPACE 75 bool "User_space thermal governor" 76 help 77 Enable this to let the user space manage the platform thermals. 78 79config CPU_THERMAL 80 bool "generic cpu cooling support" 81 depends on CPU_FREQ 82 help 83 This implements the generic cpu cooling mechanism through frequency 84 reduction. An ACPI version of this already exists 85 (drivers/acpi/processor_thermal.c). 86 This will be useful for platforms using the generic thermal interface 87 and not the ACPI interface. 88 89 If you want this support, you should say Y here. 90 91config THERMAL_EMULATION 92 bool "Thermal emulation mode support" 93 help 94 Enable this option to make a emul_temp sysfs node in thermal zone 95 directory to support temperature emulation. With emulation sysfs node, 96 user can manually input temperature and test the different trip 97 threshold behaviour for simulation purpose. 98 99 WARNING: Be careful while enabling this option on production systems, 100 because userland can easily disable the thermal policy by simply 101 flooding this sysfs node with low temperature values. 102 103config IMX_THERMAL 104 tristate "Temperature sensor driver for Freescale i.MX SoCs" 105 depends on CPU_THERMAL 106 depends on MFD_SYSCON 107 depends on OF 108 help 109 Support for Temperature Monitor (TEMPMON) found on Freescale i.MX SoCs. 110 It supports one critical trip point and one passive trip point. The 111 cpufreq is used as the cooling device to throttle CPUs when the 112 passive trip is crossed. 113 114config SPEAR_THERMAL 115 bool "SPEAr thermal sensor driver" 116 depends on PLAT_SPEAR 117 depends on OF 118 help 119 Enable this to plug the SPEAr thermal sensor driver into the Linux 120 thermal framework. 121 122config RCAR_THERMAL 123 tristate "Renesas R-Car thermal driver" 124 depends on ARCH_SHMOBILE 125 help 126 Enable this to plug the R-Car thermal sensor driver into the Linux 127 thermal framework. 128 129config KIRKWOOD_THERMAL 130 tristate "Temperature sensor on Marvell Kirkwood SoCs" 131 depends on ARCH_KIRKWOOD 132 depends on OF 133 help 134 Support for the Kirkwood thermal sensor driver into the Linux thermal 135 framework.
