	  possible powercap in Watt units

	- powercap-max : This file provides the maximum
	  possible powercap in Watt units

	- powercap-current : This file provides the current
	  powercap set on the system. Writing to this file
	  creates a request for setting a new-powercap. The
	  powercap requested must be between powercap-min
	  and powercap-max.
