intel_lpmd(8) System Manager's Manual intel_lpmd(8) NAME intel_lpmd - Intel Energy Optimizer (LPMD) Daemon SYNOPSIS intel_lpmd [ OPTIONS ] DESCRIPTION intel_lpmd is a Linux daemon used for energy optimization on Intel hybrid systems. This daemon uses a configuration file "intel_lpmd_config.xml". Based on the configuration, it will choose right set of CPUs to enable. For example, this daemon can monitor system utilization and choose a set of low power CPUs to enable and disable the rest. This enable disable of CPUs are done using Linux cpuset feature of intel power clamp driver. There is a control utility distributed along with this daemon. This control utility is called "intel_lpmd_control". This utility can be used to set different modes for this daemon. For example: intel_lpmd_control ON To turn on low power mode operation. intel_lpmd_control OFF To turn off low power mode operation. intel_lpmd_control AUTO To turn on low power mode operation in auto mode, which allows low power mode based on system utilization. OPTIONS -h --help Print the help message --version Print intel_lpmd version and exit --no-daemon Don't run as a daemon: Default is daemon mode --systemd Assume daemon is started by systemd --loglevel= log severity: can be info or debug --dbus-enable Enable Dbus server to receive requests via Dbus --ignore-platform-check Ignore platform check EXAMPLES intel_lpmd --loglevel=info --no-daemon --dbus-enable Run intel_lpmd with log directed to stdout intel_lpmd --systemd --dbus-enable Run intel_lpmd as a service with logs directed to system journal SEE ALSO intel_lpmd_config.xml(5) AUTHOR Written by Zhang Rui 1 Jun 2023 intel_lpmd(8)
