Tashkinov @ 2011-12-25 18:36 UTC (permalink / raw) To: linux-kernel; +Cc: davej, cpufreq Hello, On my Intel Core i5 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. Best wishes, Artem ^ permalink raw reply [flat|nested] only message in thread
