powertop

[Chris Murphy]

[root at f25h ~]# ls -l /var/cache/powertop/
total 0
-rw-r--r--. 1 root root 0 Dec 29 14:49 saved_parameters.powertop
-rw-r--r--. 1 root root 0 Dec 29 14:49 saved_results.powertop

These files are always 0 length files. I'm not finding that any of the
calibration runs I've done are actually getting saved.

And each time I do a calibration...

[root at f25h ~]# powertop -c
modprobe cpufreq_stats failedLoaded 0 prior measurements

That suggests there are no measurements. So... is it broken on F25 or
am I missing something? I've asked on the powertop list and there's
been no reply.

Hi Chris,
I tried now first installing the powertop rpm and than running it, on
a Fedora 25 x86_64 platform, and I get exactly the same results:
...
ls /var/cache/power* -l
total 0
-rw-r--r--. 1 root root 0 Jan 11 19:30 saved_parameters.powertop
-rw-r--r--. 1 root root 0 Jan 11 19:30 saved_results.powertop
desku:~$powertop -c
modprobe cpufreq_stats failedLoaded 0 prior measurements
RAPL device for cpu 0
RAPL device for cpu 0...

I don't know what does this message mean, whether it indicates some
anomaly or not.

I get that, but lots of other stuff as well (powertop-2.8-2.fc24.x86_64
on an F25 system):

Then it goes into a "top"-like display. After exiting, both the
saved_parameters.powertop and saved_results.powertop mtime stamps get
updated (although the saved_parameters.powertop file remains empty).

Try running with "--debug" set?

So your case is different. Are you running Fedora 24 or Fedora 25. I'm
on Fedora 25 and I'm only seeing an fc24 package, that's what I've got
installed:

powertop-2.8-2.fc24.x86_64

Did that. No additional information. Also the audit log doesn't report
anything, no AVC denial either. The time stamp of the /var/cache files
changes to coincide with the powertop run, but still it's a zero
length file with nothing in it. I'm curious if yours are also zero
length files.

Nope:
