The sysfs layout looks as below:
# ls /sys/firmware/opal/powercap/
system-powercap

# ls /sys/firmware/opal/powercap/system-powercap/
powercap-current powercap-max powercap-min

# grep . /sys/firmware/opal/powercap/system-powercap/*
/sys/firmware/opal/powercap/system-powercap/powercap-current:2375
/sys/firmware/opal/powercap/system-powercap/powercap-max:2375
/sys/firmware/opal/powercap/system-powercap/powercap-min:1945

Thanks and Regards,
Shilpa
