https://bugzilla.kernel.org/show_bug.cgi?id=19702 --- Comment #48 from Peter Ganzhorn <peter.ganzhorn@xxxxxxxxxxxxxx> 2010-11-09 17:38:09 --- I modified to patch like you suggested: + if (cpu_has(c, X86_FEATURE_APERFMPERF)) { + if (disable_average) { + printk(KERN_INFO "acpi-cpufreq: average (aperf/mperf) " + "accounting disabled by user\n"); + clear_cpu_cap(c, X86_FEATURE_APERFMPERF); + } + else + acpi_cpufreq_driver.getavg = cpufreq_get_measured_perf; + } Will the scheduler adapt to the changed cpu features with only that single change? Since the sched code probably gets initialized earlier, I wonder if it will notice the change. Anyways, the system feels a bit more responsive with the modification to the patch, but that might be a psychologic deception since I know that I made that change... -- 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
