We have done some experiment with idle injection on Intel platforms. The idea is to use the increasingly power efficient package level C-states for power capping and passive thermal control. Documentation is included in the patch to explain the theory of operation, performance implication, calibration, scalability, and user interface. Please refer to the following file for more details. Documentation/thermal/intel_powerclamp.txt Arjan van de Ven created the original idea and driver, I have been refining driver in hope that they can be to be useful beyond a proof of concept.
