[PATCH linux-next] cpufreq: ondemand: Calculate gradient of CPU load to early increase frequency

2013-02-20 Thread Stratos Karafotis
Instead of checking only the absolute value of CPU load_freq to increase frequency, we detect forthcoming CPU load rise and increase frequency earlier. Every sampling rate, we calculate the gradient of load_freq. If it is too steep we assume that the load most probably will go over up_threshold
