As described in the prerequisites section, the package name is distribution dependant.
On my distribution the original package name is phython3-gnuplot,
and it is working fine.
sys.version_info(major=3, minor=8, micro=10, releaselevel='final', serial=0)
I don't currently have python3-pygnuplot installed, and so this patch breaks
the intel_pstate_tracer for me.
So, I installed the python3-pygnuplot package, and it still didn't work, as there
still wasn't a pygnuplot module to import.
So, I found something called PyGnuplot.py and so changed to that and got further.
But then it got upset with:
File "./intel_pstate_tracer.py.amd", line 298, in common_gnuplot_settings
g_plot = gnuplot.Gnuplot(persist=1)
NameError: name 'gnuplot' is not defined
I gave up and returned to the unpatched
intel_pstate_tracer.py
And checked that is still worked fine. It did.
So, I do not accept this proposed patch.
Not really related, but for a few years now I have been meaning to
change the minimum python version prerequisite to >= 3.0 and
to change the shebang line from this:
#!/usr/bin/env python
To this:
#!/usr/bin/env python3
I have to use the latter version on my distro.
Back when I looked into it, things were inconsistent,
so I didn't know what to do. The kernel tree has 52 .py files
of the latter shebang and 11 of the former.
