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

| If you want this code to be compiled in, say Y here. |

| help |
| 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 Plane 0), graphics uncore (Power Plane |
| 1), etc. |

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