   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.

  27           This enables support for the Intel Running Average Power Limit (RAPL)
  28           technology via MSR interface, which allows power limits to be enforced
  29           and monitored on modern Intel processors (Sandy Bridge and later).

  31           In RAPL, the platform level settings are divided into domains for
  32           fine grained control. These domains include processor package, DRAM
  33           controller, CPU core (Power Plance 0), graphics uncore (Power Plane
  34           1), etc.

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