19                 contains below sysfs attributes:
20
21                 - powercap-min : This file provides the minimum
22                   possible powercap in Watt units
23
24                 - powercap-max : This file provides the maximum
25                   possible powercap in Watt units
26
27                 - powercap-current : This file provides the current
28                   powercap set on the system. Writing to this file
29                   creates a request for setting a new-powercap. The
30                   powercap requested must be between powercap-min
31                   and powercap-max.
