TuneD supports profiles to adjust different power/performance characteristics depending upon the common use-cases or alternatively fully-customized configurations as well. Plus monitoring via the TuneD daemon in looking out for any changes.
With TuneD 2.26 there are various tuned-ppd adjustments, fixing instance priority inheritance, SCSI default changes, support for MMC devices within the disk plug-in, P-State driver changes for real-time systems, and other fixes/changes based on internal Red Hat customer tickets.
The TuneD 2.26 source code is available via GitHub . Those wanting to learn more about this project from Red Hat's Performance Team can do so via TuneD-Project.org .
