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