Mm. Register a generic thermal class device and then generate a uevent? It'd be nice to do this in a generic "something has just gone wrong" way, which we could then also do for critical notifications in ACPI thermal zones. > Again, thanks to that unnamed official help!

We need decent infrastructure for exposing the reason for the wakeup - ACPI can also provide this under various circumstances, but right now we don't seem to do anything terribly useful with it. What will basically happen now is that the machine will wake up, userspace will (with luck) notice that the power is critical and either do a hibernation or clean shutdown. The wakeup event is bonus information. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ ibm-acpi-devel mailing list ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/ibm-acpi-devel
