Usually it's made up of one or more thermal 11 zone and cooling device. 12 Each thermal zone contains its own temperature, trip points, 13 cooling devices. 14 All platforms with ACPI thermal support can use this driver. 15 If you want this support, you should say Y here. 16 17if THERMAL 18 19config THERMAL_STATISTICS 20 bool "Thermal state transition statistics" 21 help 22 Export thermal state transition statistics information through sysfs. 23 24 If in doubt, say N. 25 26config THERMAL_EMERGENCY_POWEROFF_DELAY_MS 27 int "Emergency poweroff delay in milli-seconds" 28 default 0 29 help 30 Thermal subsystem will issue a graceful shutdown when 31 critical temperatures are reached using orderly_poweroff().

Similarly to the critical trip point, 36 the delay should be carefully profiled so as to give adequate 37 time for orderly_poweroff() to finish on regular execution. 38 If set to 0 emergency poweroff will not be supported. 39 40 In doubt, leave as 0. 41 42config THERMAL_HWMON 43 bool 44 prompt "Expose thermal sensors as hwmon device" 45 depends on HWMON=y || HWMON=THERMAL 46 default y 47 help 48 In case a sensor is registered with the thermal 49 framework, this option will also register it 50 as a hwmon.
