=====================
|
||||
|
||||
The framework includes a simple notification mechanism, in the form of a
|
||||
netlink event. Netlink socket initialization is done during the _init_
|
||||
of the framework. Drivers which intend to use the notification mechanism
|
||||
just need to call thermal_generate_netlink_event() with two arguments viz
|
||||
(originator, event). The originator is a pointer to struct thermal_zone_device
|
||||
from where the event has been originated. An integer which represents the
|
||||
thermal zone device will be used in the message to identify the zone. The
|
||||
event will be one of:{THERMAL_AUX0, THERMAL_AUX1, THERMAL_CRITICAL,
|
||||
THERMAL_DEV_FAULT}. Notification can be sent when the current temperature
|
||||
crosses any of the configured thresholds.
