Abstract:
A method includes capturing an interaction of a user of a data processing device therewith at a level of a user space through a process executing on the data processing device, and communicating the captured user interaction as an event from the user space to a kernel space associated with an operating system executing on the data processing device. The method also includes incorporating, through the kernel space, the communicated event as a feedback to an algorithm executing on a processor of the data processing device communicatively coupled to a memory. The algorithm is configured to modify a current performance state of the processor based on threshold levels of utilization of the processor. Further, the method includes automatically switching, based on the algorithm execution, the current performance state of the processor to a higher power state or a lower power state thereof additionally in accordance with the communicated event.
