Uncore support is currently worked on #576.
If you mean the following line from the powersave
TuneD profile:
governor=ondemand|powersave
It means governor is set to ondemand
and if not possible/supported/available it will fallback to powersave
governor.
Generally, the powersave
TuneD profile is very performance throttled. For optimal power consumption/performance the balanced
profile is usually better choice. For good performance the throughput-performance
is usually the best (it is also the default profile on RHEL/CentOS for servers). For work servers you can e.g. switch to powersave
profile during off business hours and back to throughput-performance
on business hours or you can keep it on balanced
and it will try to balance performance/power automatically according to the current load.
I am new to tuned and try to use it to regulate power consumption of my server. I saw words like ondemand | powersave in the profiles. Do these refer to the cpufreq governors? How does tuned work behind the scene in adjusting core/uncore frequencies. Any help is greatly appreciated
