| 8 | help | |
| 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. | |

| 31 | In RAPL, the platform level settings are divided into domains for | |
| 32 | fine grained control. These domains include processor package, DRAM | |
| f8fee6e6 | 33 | controller, CPU core (Power Plane 0), graphics uncore (Power Plane |

| 41 | This enables support for the idle injection framework. It | |
| 42 | provides a way to force idle periods on a set of specified | |

| 44 | synchronously on a set of specified CPUs or alternatively | |
| 45 | on a per CPU basis. | |
