I ran into the issue again with 3.7.2, and although the command does set scaling_max_frequency to equal scaling_min_frequency, turbostat still shows the core running at a much higher frequency: root@sierra:/sys/devices/system/cpu/cpu0/cpufreq# cat scaling_min_freq > scaling_max_freq root@sierra:/sys/devices/system/cpu/cpu0/cpufreq# cat scaling_max_freq 800000 root@sierra:/sys/devices/system/cpu/cpu0/cpufreq# turbostat cor CPU %c0 GHz TSC %c1 %c3 %c6 %c7 %pc2 %pc3 %pc6 %pc7 0.54 2.04 1.99 0.99 0.04 0.00 98.44 0.00 0.00 0.00 0.00 0 0 1.09 2.00 1.99 0.78 0.06 0.00 98.06 0.00 0.00 0.00 0.00 0 1 0.04 1.99 1.99 1.83 1 2 0.52 2.00 1.99 0.38 0.00 0.00 99.10 1 3 0.08 1.99 1.99 0.81 2 4 1.14 2.17 1.99 0.26 0.01 0.00 98.59 2 5 0.01 1.99 1.99 1.39 3 6 1.42 1.99 1.99 0.51 0.07 0.00 98.00 3 7 0.01 2.00 1.99 1.91 cor CPU %c0 GHz TSC %c1 %c3 %c6 %c7 %pc2 %pc3 %pc6 %pc7 0.31 2.01 1.99 0.70 0.02 0.00 98.97 0.00 0.00 0.00 0.00 0 0 0.92 1.99 1.99 0.68 0.03 0.00 98.37 0.00 0.00 0.00 0.00 0 1 0.02 1.99 1.99 1.58 1 2 0.27 1.99 1.99 0.36 0.00 0.00 99.37 1 3 0.10 1.99 1.99 0.53 2 4 0.57 2.05 1.99 0.15 0.01 0.00 99.27 2 5 0.01 2.00 1.99 0.71 3 6 0.47 1.99 1.99 0.64 0.02 0.00 98.87 3 7 0.12 1.99 1.99 0.99 -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
