7 bool "Generic powercap sysfs driver"
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

27 This enables support for the Intel Running Average Power Limit (RAPL)
28 technology via MSR interface, which allows power limits to be enforced
29 and monitored on modern Intel processors (Sandy Bridge and later).
31 In RAPL, the platform level settings are divided into domains for
32 fine grained control. These domains include processor package, DRAM
33 controller, CPU core (Power Plance 0), graphics uncore (Power Plane
37 bool "Idle injection framework"
41 This enables support for the idle injection framework. It
42 provides a way to force idle periods on a set of specified
43 CPUs for power capping. Idle period can be injected
