intel_lpmd8
Intel energy optimizer (lpmd) daemon
Usage
intel_lpmd [OPTIONS]
Overview
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.
