<HTML><BODY>I installed OpenSuSE 12.3/x86-64 now. I may now say about the reasons why I am afraid of loading of cpufreq modules.<br><br>1) I found in /var/log/messages pairs of strings about governor like<br><br>[kernel] "cpuidle: using governor ladder"<br>[kernel] "cpuidle: using governor menu"<br><br>and strange for me<br>[kernel] ENERGY_PERF_BIAS: Set to 'normal', was 'performance'<br>[kernel] ENERGY_PERF_BIAS: View and update with x86_energy_perf_policy(8)<br><br>2) The presence on installed system of /sys/devices/system/cpu/cpufreq<br> /sys/devices/system/cpu/cpu0/cpuidle<br> directories. cpuidle directories contains state0, state1 etc directories w/non-empty files.<br><br>3) But to prevent cpu frequency changes I suppressed all like possibilities in BIOS.<br>4) And I don't have (as I wrote in my previous Beowulf message) <br>/sys/devices/system/cpu/cpu0/cpufreq files.<br><br>Just the presence of this file is used by my /etc/init.d/cpufreq script as test of needs to load cpufreq kernel modules.<br><br>5) lsmod says that there is no cpufreq modules loaded.<br>Any comments ? Am I everywhere here right and should I ignore my afraids about kernel messages and presence of some /sys/devices/system/cpu/...... files ?<br><br>Mikhail Kuzminsky<br>Computer Assistance to Chemical Research Center RAS<br>Zelinsky Institute of Organic Chemistry<br>Moscow<br><br><br><br> <br><br><br></BODY></HTML>
