LIKWID-SETFREQ(1) |
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.
