- 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.

- 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.

- This enables Qualcomm Technologies, Inc. epm hardware
- device driver. It provides to measure different pmic
- regulators or bucks power consumption data in different
- modes. It exposes these data to userspace clients via
- powercap sysfs interface.
