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.

24	  This enables support for the Intel Running Average Power Limit (RAPL)
25	  technology which allows power limits to be enforced and monitored on
26	  modern Intel processors (Sandy Bridge and later).
27
28	  In RAPL, the platform level settings are divided into domains for
29	  fine grained control. These domains include processor package, DRAM
30	  controller, CPU core (Power Plance 0), graphics uncore (Power Plane
31	  1), etc.

37	help
38	  This enables support for the idle injection framework. It
39	  provides a way to force idle periods on a set of specified
40	  CPUs for power capping. Idle period can be injected
41	  synchronously on a set of specified CPUs or alternatively
42	  on a per CPU basis.
