Additionally,the Linux kernel has begun to expose RAPL-based power management via the sysfs powercap interface,which provides simpler and safer access to the low-level power controls.The Linux perf command-line interface has begun exposing and managing some of the hardware counters,but the power management is still handled by accessing the sysfs powercap filesystem.
