Sorry for delayed response -- I am currently unable to read the mailbox you sent this to. The sysfs battery class stuff (which also covers AC since they're really quite similar) is merged into 2.6.23. You get a uevent when stuff changes, although the precise details of _when_ you get that uevent are dependent on the back end, and you might find that some back ends don't do it yet at all. We could do with standardising that somehow, or at least having some way to let userspace _know_ that it needs polling. The ACPI back end isn't yet merged -- it's being developed by Alexey Starikovskiy, and can be found on the linux-acpi mailing list: http://www.mail-archive.com/linux-acpi@xxxxxxxxxxxxxxx/msg08858.html http://www.mail-archive.com/linux-acpi@xxxxxxxxxxxxxxx/msg08856.html http://www.mail-archive.com/linux-acpi@xxxxxxxxxxxxxxx/msg08859.html http://www.mail-archive.com/linux-acpi@xxxxxxxxxxxxxxx/msg08857.html http://www.mail-archive.com/linux-acpi@xxxxxxxxxxxxxxx/msg08855.html -- dwmw2 _______________________________________________ Fedora-kernel-list mailing list Fedora-kernel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-kernel-list
