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 depends on HWMON=y || HWMON=THERMAL 21 default y 22 23choice 24 prompt "Default Thermal governor" 25 default THERMAL_DEFAULT_GOV_STEP_WISE 26 help 27 This option sets which thermal governor shall be loaded at 28 startup.

This throttles the 42 devices based on their 'contribution' to a zone. The 43 contribution should be provided through platform data. 44 45config THERMAL_DEFAULT_GOV_USER_SPACE 46 bool "user_space" 47 select THERMAL_GOV_USER_SPACE 48 help 49 Select this if you want to let the user space manage the 50 lpatform thermals. 51 52endchoice 53 54config THERMAL_GOV_FAIR_SHARE 55 bool "Fair-share thermal governor" 56 help 57 Enable this to manage platform thermals using fair-share governor. 58 59config THERMAL_GOV_STEP_WISE 60 bool "Step_wise thermal governor" 61 help 62 Enable this to manage platform thermals using a simple linear 63 64config THERMAL_GOV_USER_SPACE 65 bool "User_space thermal governor" 66 help 67 Enable this to let the user space manage the platform thermals. 68 69config CPU_THERMAL 70 bool "generic cpu cooling support" 71 depends on CPU_FREQ 72 select CPU_FREQ_TABLE 73 help 74 This implements the generic cpu cooling mechanism through frequency 75 reduction. An ACPI version of this already exists 76 (drivers/acpi/processor_thermal.c). 77 This will be useful for platforms using the generic thermal interface 78 and not the ACPI interface. 79 80 If you want this support, you should say Y here. 81 82config THERMAL_EMULATION 83 bool "Thermal emulation mode support" 84 help 85 Enable this option to make a emul_temp sysfs node in thermal zone 86 directory to support temperature emulation. With emulation sysfs node, 87 user can manually input temperature and test the different trip 88 threshold behaviour for simulation purpose. 89 90 WARNING: Be careful while enabling this option on production systems, 91 because userland can easily disable the thermal policy by simply 92 flooding this sysfs node with low temperature values. 93 94config SPEAR_THERMAL 95 bool "SPEAr thermal sensor driver" 96 depends on PLAT_SPEAR 97 depends on OF 98 help 99 Enable this to plug the SPEAr thermal sensor driver into the Linux 100 thermal framework 101 102config RCAR_THERMAL 103 tristate "Renesas R-Car thermal driver" 104 depends on ARCH_SHMOBILE 105 help 106 Enable this to plug the R-Car thermal sensor driver into the Linux 107 thermal framework 108 109config KIRKWOOD_THERMAL 110 tristate "Temperature sensor on Marvell Kirkwood SoCs" 111 depends on ARCH_KIRKWOOD 112 depends on OF 113 help 114 Support for the Kirkwood thermal sensor driver into the Linux thermal 115 framework.
