PowerTOP
open-in-new
<h2 id="usage">Usage</h2> <p>The original focus was on <a href="/facts/Advanced_Configuration_and_Power_Interface/GnLLzfyr">CPU sleep states</a>, and showing the programs or drivers responsible for "wakeups" which prevent CPUs entering sleep states. A database of known problems automatically provides more user friendly "tips" for specific sources of wakeups. However, it also shows information on <a href="/facts/Advanced_Configuration_and_Power_Interface/GnLLzfyr">CPU frequency scaling</a>. Over time the database has been expanded to include tips on a wide range of power consumption issues. </p> <h2 id="project-activity">Project activity</h2> <p>The latest release of PowerTOP (version 2.15) was made public on September 29, 2022.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> The project is hosted on <a href="/facts/GitHub/n1hNCsc3">GitHub</a>.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p> <h2 id="see-also">See also</h2> <ul> <li>Energy portal</li><li>Free and open-source software portal</li></ul> <ul><li><a href="/facts/Power_management/fWv2k2sP">Power management</a></li> <li><a href="/facts/Green_computing/SpV1lJg2">Green computing</a></li> <li><a href="/facts/LatencyTOP/extlyWsK">LatencyTOP</a></li> <li><a href="/facts/Top_(software)/QDeL7v2T">top (software)</a></li> <li><a href="/facts/Run-time_estimation_of_system_and_sub-system_level_power_consumption/1Qqsrcf7">Run-time estimation of system and sub-system level power consumption</a></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="https://01.org/powertop/">Official website</a></li> <li><a href="https://github.com/fenrus75/powertop">Version Control Repository</a></li> <li><a href="http://opensolaris.org/os/project/tesla/Work/Powertop">Powertop for OpenSolaris</a> – part of Project Tesla</li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Gray, James (15 February 2008).
