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

23 | This enables support for the Intel Running Average Power Limit (RAPL) | |
24 | technology which allows power limits to be enforced and monitored on | |
25 | modern Intel processors (Sandy Bridge and later). | |
26 | ||
27 | In RAPL, the platform level settings are divided into domains for | |
28 | fine grained control. These domains include processor package, DRAM | |
29 | controller, CPU core (Power Plance 0), graphics uncore (Power Plane | |
30 | 1), etc. | |
