Mageia released an update for this tool (maybe today or just a couple of days ago since my laptop was off for 3 days) and I noticed that the available governors on the updated version are:
powersave
performance
Previously, I had the following:
powersave
performance
conservative
ondemand
userspace
I noticed that the behavior of powersave seems to be somewhat similar to ondemand and conservative although it spikes more frequently than the previous version and it doesn't seem to be lowering to 1200 mhz, which is the lowest clock available for my processor (I view my CPU frequency via Conky). I would like to have that 1.2GHZ clock when my Laptop is idle for the obvious reason of conserving power and lowering temperature. What I liked about the update is that it now reaches the 3.1GHZ which is utilizes the maximum automatic "over" clock rate designed for my processor wherein for the previous version, it can only be set to 2.5GHZ max.
Here are the commands I ran for reference (this is after the update). I was not able to take note of the previous version of cpupower though
cpupower frequency-set -u 1200000
Setting cpu: 0
Setting cpu: 1
Setting cpu: 2
Setting cpu: 3
cpupower frequency-set -u 3100000
Setting cpu: 0
Setting cpu: 1
Setting cpu: 2
Setting cpu: 3
cpupower frequency-set -g powersave
Setting cpu: 0
Setting cpu: 1
Setting cpu: 2
Setting cpu: 3
cpupower --version
cpupower 3.12.18-1.mga4
My processor is an Intel i5 3210m.
So my question is: Does cpupower not provide a governor or setting that I can force my processor to run at a specific speed? e.g. I would only like to run it at 1.2GHZ consistently instead of stepping up/down since it will be useful when I run my laptop on batteries.
Thank you in advance!
