https://bugzilla.kernel.org/show_bug.cgi?id=42671 Summary: cpufreq userspace governor doesn't work on Intel Core 2 Gen 2 CPUs Product: Power Management Version: 2.5 Kernel Version: All known Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: cpufreq AssignedTo: cpufreq@xxxxxxxxxxxxxxx ReportedBy: t.artem@xxxxxxxxxxxx Regression: No On my Intel Core i5 2500 CPU with acpi-cpufreq module loaded I do this # echo 2000000 | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_setspeed then # cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq 2000000 2000000 2000000 2000000 so theoretically it should work. However i7z (http://code.google.com/p/i7z/) shows that CPU frequency is freely floating and turbo boost gets enabled as soon as I have any discernible load, in other words userspace CPU frequency driver doesn't work at all and it doesn't really enforce the specified CPU frequency. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- 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
