+menuconfig POWERCAP
+ bool "Generic powercap sysfs driver"
+ 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.

+config INTEL_RAPL
+ tristate "Intel RAPL Support"
+ depends on X86 && IOSF_MBI
+ default n
+ ---help---
+ This enables support for the Intel Running Average Power Limit (RAPL)
+ technology 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 Plance 0), graphics uncore (Power Plane
+ 1), etc.
+
+config IDLE_INJECT
+ bool "Idle injection framework"
+ depends on CPU_IDLE
+ default n
+ 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.
