PowerCap: Add class driver The power capping framework providing a consistent interface between the kernel and user space that allows power capping drivers to expose their settings to user space in a uniform way. The overall design of the framework is described in the documentation added by the previous patch in this series.

PowerCap: Introduce Intel RAPL power capping driver The Intel Running Average Power Limit (RAPL) technology provides platform software with the ability to monitor, control, and get notifications on power usage. This feature is present in all Sandy Bridge and later Intel processors. Newer models allow more fine grained controls to be applied. In RAPL, power control is divided into domains, which include package, DRAM controller, CPU core (Power Plane 0), graphics uncore (power plane 1), etc. The purpose of this driver is to expose the RAPL settings to userspace. Overall, RAPL fits in the new powercap class driver in that platform level power capping controls are exposed via this generic interface. This driver is based on an earlier patch from Zhang Rui. However, while the previous work was mainly focused on thermal monitoring the focus here is on the usability from user space perspective.

powercap / idle_inject: Add an idle injection framework Initially, the cpu_cooling device for ARM was changed by adding a new policy inserting idle cycles. The intel_powerclamp driver does a similar action. Instead of implementing idle injections privately in the cpu_cooling device, move the idle injection code in a dedicated framework and give the opportunity to other frameworks to make use of it. The framework relies on the smpboot kthreads which handles via its main loop the common code for hotplugging and [un]parking. This code was previously tested with the cpu cooling device and went through several iterations. It results now in split code and API exported in the header file. It was tested with the cpu cooling device with success.
