CPUPOWER-FREQUENCY-SET(1) cpupower Manual CPUPOWER-FREQUENCY-SET(1)NAME
cpupower frequency-set - A small tool which allows to modify cpufreq settings.
SYNTAX
cpupower [ -c cpu ] frequency-set [options]
DESCRIPTION
cpupower frequency-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scal-
ing_set_speed" all the time.
OPTIONS -d --min <FREQ>
new minimum CPU frequency the governor may select.
-u --max <FREQ>
new maximum CPU frequency the governor may select.
-g --governor <GOV>
new cpufreq governor.
-f --freq <FREQ>
specific frequency to be set. Requires userspace governor to be available and loaded.
-r --related
modify all hardware-related CPUs at the same time
REMARKS
By default values are applied on all cores. How to modify single core configurations is described in the cpupower(1) manpage in the --cpu
option section.
The -f FREQ, --freq FREQ parameter cannot be combined with any other parameter.
FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (fre-
quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).
On Linux kernels up to 2.6.29, the -r or --related parameter is ignored.

DESCRIPTION
cpufreq-set allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed" all
the time.
OPTIONS -c --cpu <CPU>
number of CPU where cpufreq settings shall be modified.
-d --min <FREQ>
new minimum CPU frequency the governor may select.
-u --max <FREQ>
new maximum CPU frequency the governor may select.
-g --governor <GOV>
new cpufreq governor.
-f --freq <FREQ>
specific frequency to be set. Requires userspace governor to be available and loaded.
-r --related
modify all hardware-related CPUs at the same time
-h --help
Prints out the help screen.
REMARKS
Omitting the -c or --cpu argument is equivalent to setting it to zero.
The -f FREQ, --freq FREQ parameter cannot be combined with any other parameter except the -c CPU, --cpu CPU parameter.
FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (fre-
quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).

The file /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_frequency reads a value of 800 Mhz . The powertop tool also suggested that 800 Mhz w3as the minimum frequency being used . I changed the above-mentioned file to 1.6 GHz and monitored powertop tool again . To my surprise, it still said that... (3 Replies)

Hi Friends-
What does it mean by 2 cpu cores, 3 cpu cores? Does it mean 2 separate cpus or what is it exactly ?
Kindly explain a bit in detail.

so we frequently receive a lot of cpu related alerts. all types of checks have been created to keep an eye on the cpu but a lot of these checks make too much noise as the CPU is always being seen as high. the system and application owners say there's no issue with the cpu.
