Peter Anvin" , Ingo Molnar , Zhang Rui , Joe Perches , Rob Landley , Arjan van de Ven , Paul McKenney , Jacob Pan List-Id: linux-pm@vger.kernel.org v6 changes: - clamp module parameters duration and window size, reword warning messages when input parameters are out of range. 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.
