Since the ACPI meter receives ACPI events, it seems logical to me that these events should be passed through to ACPI clients. It also seems logical that hwmon clients shouldn't have to know about ACPI netlink sockets either, so I'll combine them both and see what popular consensus thinks of that. :) Therefore, I updated the patch to make the appropriate sysfs files pollable, and the hwmon sysfs documentation to state that they can be polled. > > So it goes with ACPI.

Ok, I'll clarify the documentation to say that those two scenarios are possible, and to contact the machine vendor for details. --D
