16 Here <control type> determines how the power is going to be
17 controlled. A <control type> can contain multiple power zones.
22 Contact: linux-pm@vger.kernel.org
24 This allows to enable/disable power capping for a "control type".
25 This status affects every power zone using this "control_type.

30 Contact: linux-pm@vger.kernel.org
32 A power zone is a single or a collection of devices, which can
33 be independently monitored and controlled. A power zone sysfs
35 E.g. intel-rapl:0:1:1.
37 What: /sys/class/powercap/<control type>/<power zone>/<child power zone>
40 Contact: linux-pm@vger.kernel.org
42 Power zones may be organized in a hierarchy in which child
43 power zones provide monitoring and control for a subset of
45 power zone for a whole CPU package, each CPU core in it can
46 be a child power zone.
