|  | bool "Thermal drivers" | 
|  | help | 
|  | Thermal drivers offer a generic mechanism for | 
|  | thermal management. Usually it's made up of one or more thermal | 
|  | zones and cooling devices. | 
|  | Each thermal zone contains its own temperature, trip points, | 
|  | and cooling devices. | 
|  | All platforms with ACPI or Open Firmware thermal support can use | 
|  | this driver. | 
|  | If you want this support, you should say Y here. |

|  | Thermal subsystem will issue a graceful shutdown when | 
|  | critical temperatures are reached using orderly_poweroff(). In | 
|  | case of failure of an orderly_poweroff(), the thermal emergency | 
|  | poweroff kicks in after a delay has elapsed and shuts down the system. | 
|  | This config is number of milliseconds to delay before emergency | 
|  | poweroff kicks in. Similarly to the critical trip point, | 
|  | the delay should be carefully profiled so as to give adequate | 
|  | time for orderly_poweroff() to finish on regular execution. |
