The patch titled cpufreq: fix ondemand governor powersave_bias execution time misuse has been removed from the -mm tree. Its filename was cpufreq-fix-ondemand-governor-powersave_bias-execution-time-misuse.patch This patch was dropped because an alternative patch was merged The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: cpufreq: fix ondemand governor powersave_bias execution time misuse From: Youquan Song <youquan.song@xxxxxxxxxxxxxxx> Ondemand governor use powersave_bias tunable to do aggressive power save by decrease CPU average frequency. The average frequency achieve by adjust low and high frequency's execution time proportion during one sample time interval. Current kernel, only the high frequency executes in time proportion, but the low frequency wrongly execute in one whole sample time interval when powersave_bias is set. The patch fix it by set low frequency execution time to it deserved.
