| 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. | |

| 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. | |

| 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. | |
