Hi everyone,

I noticed that section 10.4 of the ACPI 4.0 spec mentions exposing power meter
hardware via the DSDT.  Is anybody currently writing a Linux driver for that
power meter interface?  Or am I volunteering for that task? :)

No, but I'm working on a prototype to send power use estimates to kvm guests.

Reading between the lines, you sort of imply that you are working on a driver?
If you are, we should coordinate efforts.
