geopmadmin(1) – tool for GEOPM system administrators
Synopsis
geopmadmin [--config-default | --config-override | --msr-allowlist] [--cpuid]
geopmadmin [--help | --version]
Description
The geopmadmin command line tool facilitates the administration of
systems that are using GEOPM. It can be used to display the path to
the GEOPM configuration files, or check the validity the contents of
those files. This tool can also be used to configure the msr-safe
kernel driver to enable the white listing of all MSR access required
by GEOPM. When run with no arguments geopmadmin will parse the
default and override configuration files on the system and print out
in a human readable format the values determined by these files.
Options
- --help
Print brief summary of the command line usage information, then exit.
- --version

- -d, --config-default
Print the path to the GEOPM configuration file that controls the default values for the system.
- -o, --config-override
Print the path to the GEOPM configuration file that controls the override values for the system.
- -a, --msr-allowlist
Print the minimum required allowlist for the
msr-safedriver to enable all of the GEOPM features.- -c, --cpuid
Specify the
cpuidin hexadecimal to select the architecture for themsr-safeallowlist generation. If this option is not specified the architecture where the application is running will be used.
Examples
Set the msr-safe allowlist to enable GEOPM:
geopmadmin --allowlist > /dev/cpu/msr_allowlist
on a legacy msr-safe system:
geopmadmin --allowlist > /dev/cpu/msr_whitelist
