There were a lot of discussions on this a few months ago in context
of the ACPI 4 "power aggregator" which is a similar (perhaps
slightly less sophisticated) concept.

While there was a lot of talk about teaching the scheduler about this
the end result was just a driver which just starts real time threads
and then idles in them. This is in current mainline.

It might be a good idea to review these discussions in the archives.
