I don't use any Fedora kernel, so I can't tell which governors are
enabled in those. You should check the value of "CONFIG_CPU_FREQ_GOV"
in the respective .config file for your installed kernel.
In short: It seems that only "performance" and "powersave" are
No, I used the same .config in all versions that I tested. I've also
tried setting them as modules rather than built-in. This is the stock
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
And modprobing any governor module does not change the output of scaling_available_governors.
