Tested on an AMD machine with acpi-cpufreq kernel driver providing
ondemand, conservative,... governors.
Without this line, one gets:
tuned.plugins.plugin_cpu: ignoring governor 'conservative' on cpu 'cpu7', it
is not supported
when switching to balanced profile.
With this line you see:
tuned.plugins.plugin_cpu: setting governor 'ondemand' on cpu 'cpu2'
Be careful: Order matters!
tuned seem to read profile config file line by line or section by section
and directly tries to apply things.
If order of these lines are exchanged:
[modules]
cpufreq_conservative=+r
[cpu]
governor=conservative
you fall back to previous error again. Therefore the newly introduced
[modules] section is not put at the end, but nearly at top.
