Checking the DSDTs I have to hand, it seems that polling is expected on about 5% of systems via an explicit _TZP and on almost all machines via _TSP. Even on systems where thermal notifications are provided, it's still up to the OS to poll the zone to find the current temperature and take appropriate action. There's still a window for native smbus drivers to screw everything up. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
