NAME

       intel_lpmd - Intel Low Power Mode Daemon

SYNOPSIS

       intel_lpmd  [ OPTIONS ]

DESCRIPTION

       intel_lpmd  is  a  Linux daemon used to optimize active idle power. 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.
