https://bugzilla.kernel.org/show_bug.cgi?id=69821 --- Comment #4 from Chen Yu <yu.c.chen@xxxxxxxxx> --- CONFIG_NO_HZ_FULL is using ktime_get to get the idle time in get_cpu_idle_time_us, it is based on clock source, while if the kernel config is set with CONFIG_HZ_PERIODIC , the governor might get idle time by jiffies(tick, minimum unit of 4 millisecond), the former is more accurate than the latter, this might be one of the reason for the problem. I can try to reproduce and take a look. -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
