Use man pages to check command line arguments in configuration: man thermald man thermal-conf.xml

Prerequisites: Kernel Prefers kernel with Intel RAPL power capping driver : Available from Linux kernel 3.13.rc1 Intel P State driver (Available in Linux kernel stable release) Intel Power clamp driver (Available in Linux kernel stable release)

    CONFIG_X86_MSR, so that x86 MSR can be read/write from user space to control RAPL if no RAPL powecap class driver is not present.

Default
    If none of the above available cpufreq to control P states.

Building and executing on Fedora 1. Install

yum install automake
yum install gcc
yum install gcc-c++
yum install glib-devel
yum install dbus-glib-devel
yum install libxml2-devel

2 Build

./autogen.sh
 ./configure prefix=/
make
sudo make install

3

  • start service sudo systemctl start thermald.service
  • Get status sudo systemctl status thermald.service
  • Stop service sudo systemctl stop thermald.service
  1. Terminate using DBUS I/F sudo test/test_pref.sh and select TERMINATE choice.

Building on Ubuntu

  1. Install sudo apt-get install autoconf sudo apt-get install g++ sudo apt-get install libglib2.0-dev sudo apt-get install libdbus-1-dev sudo apt-get install libdbus-glib-1-dev sudo apt-get install libxml2-dev

2 Build

./autogen.sh
 ./configure prefix=/usr
make
sudo make install

(It will give error for systemd configuration, but ignore)

3. If using systemd, use

  • start service sudo systemctl start thermald.service
  • Get status sudo systemctl status thermald.service
  • Stop service sudo systemctl stop thermald.service

Version 0.2

  • Define XML interface to set configuration data. Refere to thermal-conf.xml. This allows to overide buggy Bios thermal comfiguration and also allows to extend the capability.

  • Methods can be overridden in a custom class to modify default behaviour
  • Read thermal zone and cooling devices, trip points etc,
  • Read temprature via netlink notification or via polling configurable via command line
  • Once a trip point is crossed, activate the associate cooling devices. Start with min tstate to max tstate for each cooling device.
  • Based on active or passive settings it decides the cooling devices
