intel_lpmd - Man Page

intel_lpmd [ Options ]

intel_lpmd is a Linux daemon used for energy optimization on Intel hybrid systems. This daemon uses a configuration file called "intel_lpmd_config.xml". The other installed configuration files are to be treated as best practice templates. The main configuration file should be edited by the user to enable LPMD and it's desired functionalities. Based on the configuration and system utilization LPMD can:

- choose the best set of CPU cores to enable for a given moment in time

- choose the best EPP (energe performance preference) and EPB (energy performance bias) value

- pick the best SoC power slider settings

There is a control utility distributed along with this daemon. It's called "intel_lpmd_control" and it can be used to change modes in the running LPMD instance.
