Will the Powertop Add-on be available in future updates?

Hi,

The latest blog, about testing for core update 172, says:

Obsolete gnu-netcat and powertop add-ons have been dropped.

Does this mean that powertop will not be supported in future updates?

I use powertop on all my home PCs, including IPFire where I have:

/usr/sbin/powertop --auto-tune

in /etc/sysconfig/rc.local so I have the optimal settings on boot.

My IPFire system is intel-based and obviously on all the time, so I would like to ensure that it keeps using less power.

Thank you!

Perhaps this addon would do: cpufrequtils
You could set CPUFreq Governor to Powersave
-cab

Thank you but I’m afraid not.

The powertop “auto tune” option sets the optimal values for a variety of power saving options. If an update to Powertop has new optimal values, then they are automatically applied.

I could fall back to manually changing what Powertop recommends today (see below) but the “auto tune” option is helpful as it sets what is recommended with the current version of Powertop. I’m hoping that I have misunderstood the blog post or that someone will be willing to keep maintaining Powertop.

# Power Management at boot.  Auto-tune replaces all lines below with the best values at the time!
/usr/sbin/powertop --auto-tune
#

This was discussed in the monthly Development Video Conf Call today.

Log of meeting

The decision was taken to keep Powertop as an addon in IPFire. The removal in Core Update 172 Testing will be reverted for Core Update 172 release.
