The generic thermal sysfs provides a set of interfaces for thermal zone devices (sensors)
and thermal cooling devices (fan, processor...) to register with the thermal management
solution and to be a part of it.
The generic thermal sysfs provides a set of interfaces for thermal zone
devices (sensors) and thermal cooling devices (fan, processor...) to register
with the thermal management solution and to be a part of it.
This how-to focuses on enabling new thermal zone and cooling devices to participate
in thermal management.
This solution is platform independent and any type of thermal zone devices and
cooling devices should be able to make use of the infrastructure.

3. A simple implementation
ACPI thermal zone may support multiple trip points like critical/hot/passive/active.
If an ACPI thermal zone supports critical, passive, active[0] and active[1] at the same time,
it may register itself as a thermal_zone_device (thermal_zone1) with 4 trip points in all.
It has one processor and one fan, which are both registered as thermal_cooling_device.
If the processor is listed in _PSL method, and the fan is listed in _AL0 method,
the sys I/F structure will be built like this:
