# SPDX-License-Identifier: GPL-2.0-only # # Generic power capping sysfs interface configuration # 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. if POWERCAP # Client driver configurations go 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 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. endif
