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

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.
