NAME

       thermald - start Linux thermal daemon

SYNOPSIS

       thermald  [ OPTIONS ]

DESCRIPTION

       thermald  is  a  Linux  daemon  used  to prevent the overheating of platforms. This daemon
       monitors temperature and applies compensation using available cooling methods.

       By default, it monitors CPU temperature using available CPU  digital  temperature  sensors
       and maintains CPU temperature under control, before HW takes aggressive correction action.

       Thermal  daemon looks for thermal sensors and thermal cooling drivers in the Linux thermal
       sysfs (/sys/class/thermal) and builds a list of sensors and cooling drivers. Each  of  the
       thermal sensors can optionally be binded to a cooling drivers by the in kernel drivers. In
       this case the Linux kernel thermal core can directly take actions based on the temperature
       trip points, for each sensor and associated cooling device. For example a trip temperature
       X in a sensor can be associates a cooling driver Y. So when the sensor  temperature  =  X,
       the cooling driver "Y" is activated.

       Thermal  daemon  allows  to  change  this  relationship  or  add  new  one  via  a thermal
       configuration file (thermal-conf.xml). This file is automatically created and used, if the
       platform has ACPI thermal relationship table. If not this needs to be manually configured.

       When  there  is a sensor, which has no associate cooling device, via configuration file or
       thermal relationship table, then this sensor is tested  for  relationship  with  CPU  load
       dynamically  up  to  maximum  3  times. If there is no relationship, then it is added to a
       black list of unbinded sensors and not tried again.

       Optionally thermal daemon can act as an exclusive  thermal  controller  by  using  thermal
       sysfs and acting as a user space governor.  In this case kernel thermal core is not active
       and decision is taken by thermal daemon only.

OPTIONS

       -h, --help
              Show help options.

       --version
              Print thermald version and exit.

       --no-daemon
              Don't become a daemon: Default is daemon mode.

       --loglevel=info
              log severity: info level and up.

       --loglevel=debug
              log severity: debug level and up: Max logging.

       --poll-interval
              Poll interval in seconds: Poll for zone temperature changes.  To  disable  polling,
              set  to  zero.  Polling  can only be disabled, if available temperature sensors can
              notify temperature change asynchronously.

       --dbus-enable
              Enable Dbus.

       --exclusive-control
              Act as exclusive thermal controller. This will use user-space governor for  thermal
              sysfs and take over control.
