└─>Intel RAPL Support via MSR Interface
In linux kernel since version 3.10 (release Date: 2013-06-30)
This enables support for the Intel Running Average Power Limit (RAPL)
technology via MSR interface, which allows power limits to be enforced
and monitored on modern Intel processors (Sandy Bridge and later).
In RAPL, the platform level settings are divided into domains for
fine grained control. These domains include processor package, DRAM
controller, CPU core (Power Plance 0), graphics uncore (Power Plane
1), etc.
