PID control configuration usage

[Matthew Barth]

I'm investigating the functionality and use of pid-control to what is 
currently being used on IBM's witherspoon system. Is there a PID control 
configuration being used that's upstream? I am unable to find any 
systems in the meta layers using pid-control that provides a direct 
configuration example. It looks to be used in the Intel layer that pulls 
a config together from entity-manager and presents it on dbus to 
pid-control, but I dont follow how the entity-manager json transforms to 
the consumable pid-control json. Could someone point me to a functional 
(possibly in-use) example or show the json config produced from 
entity-manager?

Thanks,
Matt
