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 via MSR Interface"
depends on X86 && IOSF_MBI
select INTEL_RAPL_CORE
help
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.
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.
config DTPM
bool "Power capping for Dynamic Thermal Power Management"
help
This enables support for the power capping for the dynamic
thermal power management userspace engine.
