Thanks Jaroslav, but I'm unsure of what to edit. If I'm removing "If a specific governor is not listed as available for your CPU" because those governors are built in, then the whole step is redundant because it says to use modprobe to enable a governor that is listed as unavailable for your CPU. If all governors are listed as available, then I assume the modprobe command is unnecessary, in which case the second step, which enables the governor, is all that's needed. Should I delete the first step?
Yes, please delete the first step (about modprobe).
Note that because I am updating this section to incorporate the cpupower command as we discussed, then this second step to enable the governor will use "cpupower frequency-info --governors"
Great, I hardly follow all the changes :). But your substitution command is not correct. "cpupower frequency-info --governors" will show all available governors, but enable the specific governor by: "cpupower frequency-set --governor GOVERNOR" or simply by "cpupower frequency-set -g GOVERNOR". This will change governer on all cores (CPUs). You can also modify governor on specific core only (if supported by HW) by using the -c switch.
The command "cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" that you've asked to be retained has also been replaced, by "cpupower frequency-info --policy".
OK, no problem, just be consistent.
I just want to be sure that this is acceptable and you don't actually want the existing cat and echo commands to be retained despite the emphasis on cpupower.
The admon box from RHEL guide that very briefly noted that there are also the sysfs "echo/cat" alternatives is enough.
