 8	help
 9	  The power capping sysfs interface allows kernel subsystems to expose power
10	  capping settings to user space in a consistent way.  Usually, it consists
11	  of multiple control types that determine which settings may be exposed and
12	  power zones representing parts of the system that can be subject to power
13	  capping.

57	  This enables support for the idle injection framework. It
58	  provides a way to force idle periods on a set of specified
59	  CPUs for power capping. Idle period can be injected
60	  synchronously on a set of specified CPUs or alternatively
61	  on a per CPU basis.
