Minor syntax change since v1.
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.
Jacob Pan (3):
tick: export nohz tick idle symbols for module use
x86/nmi: export local_touch_nmi() symbol for modules
