|
Generic Thermal Sysfs driver offers a generic mechanism for
|
||
|
|
thermal management. Usually it's made up of one or more thermal
|
||
|
|
zone and cooling device.
|
||
|
|
Each thermal zone contains its own temperature, trip points,
|
||
|
|
cooling devices.
|
||
|
|
All platforms with ACPI thermal support can use this driver.
|
||
|
|
If you want this support, you should say Y or M here.

Thermal subsystem will issue a graceful shutdown when

This config is number of milliseconds to delay before emergency

the delay should be carefully profiled so as to give adequate

The DTS will be registered as a thermal zone. There are two trip points:

hot & critical. The critical trip point default value is set by
