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_CORE
tristate
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 ARM_SCMI_POWERCAP
tristate "ARM SCMI Powercap driver"
depends on ARM_SCMI_PROTOCOL
help
This enables support for the ARM Powercap based on ARM SCMI
Powercap protocol.
ARM SCMI Powercap protocol allows power limits to be enforced
and monitored against the SCMI Powercap domains advertised as
available by the SCMI platform firmware.
When compiled as module it will be called arm_scmi_powercap.ko.
config DTPM
bool "Power capping for Dynamic Thermal Power Management (EXPERIMENTAL)"
depends on OF
help
This enables support for the power capping for the dynamic
thermal power management userspace engine.
config DTPM_CPU
bool "Add CPU power capping based on the energy model"
depends on DTPM && ENERGY_MODEL
help
This enables support for CPU power limitation based on
energy model.
config DTPM_DEVFREQ
bool "Add device power capping based on the energy model"
depends on DTPM && ENERGY_MODEL
help
This enables support for device power limitation based on
energy model.
