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.

The thermal framework has a netlink interface to do thermal

trip point crossed, cooling device update or governor

change. It is recommended to enable the feature.

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.
|
|
If set to 0 emergency poweroff will not be supported.
