tristate "Generic Thermal sysfs driver"
|
|
help
|
|
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.

help
|
|
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.

In doubt, leave as 0.
