ACPI thermal zone

acpitz* at acpi?

The acpitz driver supports ACPI Thermal Zones. Temperature information is available through this driver as a sensor which is updated every 10 seconds or, if the implementation supports it, via an event. If the temperature exceeds the ‘critical’ temperature threshold, the system will be shut down and powered off. The sensor provided by acpitz can be monitored using sysctl(8) or sensorsd(8).
