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

37	int "Emergency poweroff delay in milli-seconds"
38	default 0
39	help
40	  Thermal subsystem will issue a graceful shutdown when
41	  critical temperatures are reached using orderly_poweroff(). In
42	  case of failure of an orderly_poweroff(), the thermal emergency
43	  poweroff kicks in after a delay has elapsed and shuts down the system.
44	  This config is number of milliseconds to delay before emergency
45	  poweroff kicks in. Similarly to the critical trip point,
46	  the delay should be carefully profiled so as to give adequate
47	  time for orderly_poweroff() to finish on regular execution.
48	  If set to 0 emergency poweroff will not be supported.
49
50	  In doubt, leave as 0.

58	  In case a sensor is registered with the thermal
59	  framework, this option will also register it
60	  as a hwmon. The sensor will then have the common
61	  hwmon sysfs interface.

79config THERMAL_WRITABLE_TRIPS

111
112config THERMAL_DEFAULT_GOV_USER_SPACE

116	  The Userspace governor allows to get trip point crossed

216	  threshold behaviour for simulation purpose.
217
218	  WARNING: Be careful while enabling this option on production systems,
