NAME

likwid-setFreq - Mediator for likwid-setFrequencies(1) that performs the actual setting of CPU cores' frequency and governor.

SYNOPSIS

likwid-setFreq <coreId> <command> <frequency|governor>

OPTIONS

<command>: Valid commands are cur , min , max and gov

DESCRIPTION

likwid-setFreq is a command line application that mediates the request from likwid-setFrequencies(1) because setting a CPU core's frequency and/or governor requires root privileges. This executable must be suid-root. likwid-setFreq works only with the kernel module acpi-cpufreq. The recent intel_pstate module does not allow one to
set fixed frequencies.
