+Description: System powercap directory and attributes applicable for
+ Powernv (P8, P9) servers
+
+ This directory provides powercap information. It
+ contains below sysfs attributes:
+
+ - powercap-min : This file provides the minimum
+ 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.
