CONFIG_INTEL_RAPL: Intel RAPL Support via MSR Interface

General informations

The Linux kernel configuration item CONFIG_INTEL_RAPL has multiple definitions:

Intel RAPL Support via MSR Interface found in drivers/powercap/Kconfig

The configuration item CONFIG_INTEL_RAPL:

• prompt: Intel RAPL Support via MSR Interface
• type: tristate
• depends on: CONFIG_X86 && CONFIG_PCI
• defined in drivers/powercap/Kconfig
• found in Linux kernels: 5.3–5.19, 6.0–6.12
• modules built: intel_rapl, intel_rapl_msr

Help text

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.
