https://bugzilla.kernel.org/show_bug.cgi?id=19702 --- Comment #35 from Peter Ganzhorn <peter.ganzhorn@xxxxxxxxxxxxxx> 2010-11-01 10:49:11 --- # dmesg | grep acpi-cpufreq acpi-cpufreq: average (aperf/mperf) accounting disabled by user acpi-cpufreq: average (aperf/mperf) accounting disabled by user This patch actually *FIXED* the problem for me. Please give me some instructions on how to use cpufreq-aperf - how do I use the tool? When running it, it gives me an output like this (with the patched kernel): # cpufreq-aperf CPU Average freq(KHz) Time in C0 Time in Cx C0 percentage 000 0500250 00 sec 041 ms 00 sec 958 ms 04 001 0460230 00 sec 056 ms 00 sec 943 ms 05 000 0500250 00 sec 045 ms 00 sec 954 ms 04 001 0620310 00 sec 056 ms 00 sec 943 ms 05 000 0480240 00 sec 033 ms 00 sec 966 ms 03 001 0520260 00 sec 054 ms 00 sec 945 ms 05 000 0580290 00 sec 109 ms 00 sec 890 ms 10 001 0580290 00 sec 123 ms 00 sec 876 ms 12 000 0560280 00 sec 179 ms 00 sec 820 ms 17 001 0540270 00 sec 239 ms 00 sec 760 ms 23 Do I have to create load on one or both cpu cores? Do I have to pass particular options? And if I just have to run it, how long should I run it? -- 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
