mediocore - a more convenient cpufrequtils
What is mediocore?
mediocore is a Rust implementation of the cpufrequtils
toolkit used to get and set per-CPU-core frequency scaling governor and CPU frequency target.
Like the original cpufrequtils, it uses Linux' sysfs to retrieve and manipulate the current CPU governor parameters located under /sys/devices/system/cpu/cpu/.
The main grief with cpufreq-set
is that it only operates on single cores, so it must be wrapped in scripts (for example to set all of your cores to minimum frequency for maximum battery lifetime).
mediocores' mdcr
command provides convenient shortcuts to set parameters for all cores or display current settings.
Mediocore also sanity checks inputs by first discovering current and viable settings.
Installing
With Rust installed run cargo install mediocore
to install the mdcr utility.
Usage
Run mdcr help
to show available commands and mdcr help <subcommand>
to see per.
mdcr show
discovers and displays current/possible settings in a console friendly waymdcr show --json
writes discovered settings to stdout as jsonmdcr set [-g governor] [-l lower_threshold] [-h upper_threshold] [-c comma_separated_list_of_core_numbers]
applies the settings given via -g/-l/-h to all cores unless a set of cores is specified via -c
There are also two shortcut commands:
mdcr ps|powersave
sets cpu minimum frequency for both lower and upper frequency limits and applies powersave governor.mdcr p|performance
sets cpu maximum frequency as the upper frequency limit and applies performance governor.
