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.
