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.
