It 19*4882a593Smuzhiyun contains below sysfs attributes: 20*4882a593Smuzhiyun 21*4882a593Smuzhiyun - powercap-min : This file provides the minimum 22*4882a593Smuzhiyun possible powercap in Watt units 23*4882a593Smuzhiyun 24*4882a593Smuzhiyun - powercap-max : This file provides the maximum 25*4882a593Smuzhiyun possible powercap in Watt units 26*4882a593Smuzhiyun 27*4882a593Smuzhiyun - powercap-current : This file provides the current 28*4882a593Smuzhiyun powercap set on the system. Writing to this file 29*4882a593Smuzhiyun creates a request for setting a new-powercap. The 30*4882a593Smuzhiyun powercap requested must be between powercap-min 31*4882a593Smuzhiyun and powercap-max. 32
