Hi,

I can't find reliable up-to-date info. I have an Intel Broadwell NUC that I want to use for Audio and am informed in the AVLinux manual:

By default the 'Performance' CPU Governor is enabled, this is an absolute ' must have' setting for working with Audio and may negatively impact battery life to a small degree on laptops

I want to keep using Fedora 24, so I need this sorted. Cheers!

You can gather and configure this information using the /proc virtual file system or, in Fedora, you can install the kernel-tools package and use the cpupower command. The old Fedora 20 Power Management Guide is still relevant.

Basically:

#Install the utility
sudo dnf install kernel-tools

#Check your current cpu frequency configuration
sudo cpupower --info

#Check available governors
sudo cpupower frequency-info --governors

#Set the performance option if necessary
sudo cpupower frequency-set --governor cpufreq_performance

You can probably also control the CPU power configuration in your Intel UEFI or BIOS.

The second command should be sudo cpupower info for kernel-tools 4.11.12.
