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.
