Eh, yes, I found something else: You have constant_tsc feature, but not non-stop tsc feature. CPU idle drivers mark tsc unstable if C-states are used. If C-states also affect aperf/mperf timers, they must not used as well in this case. Can you try: idle=halt boot param Argh, intel idle driver does not recognize idle= overrides. Please try idle=halt with another patch I'll provide. Or try both params (then the patch should not be needed): intel_idle.max_cstate=0 idle=halt Does cpufreq-aperf then give you sane average frequency values in the range of min/max freq and cpufreq subsystem works as expected? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list 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
