Starting with LIKWID version 3.1.2 we included a daemon and control script to change the frequency and scaling governor of affinity regions. All operations that require only readable access to the control files in sysfs are implemented in the script. Only the writeable access is forbidden for normal users and requires a more privileged daemon.

likwid-setFrequencies can only be used in conjunction with the `acpi-cpufreq` kernel module. The `intel_pstate` kernel module, introduced with Linux kernel 3.10, does not allow to fix the clock frequency of cores. In order to deactivate the `intel_pstate` module, add `intel_pstate=disable` to the kernel command line in GRUB.
