[PATCH 0/2] Fix issues observed with selftests/amd-pstate

[Swapnil Sapkal]

This series fixes the issues observed with selftests/amd-pstate while
running performance comparison tests with different governors. First
patch changes relative paths with absolute path and also change it with
correct path wherever it is broken.
The second patch fixes error observed while importing the Gnuplot in
intel_pstate_tracer.py.

[PATCH 1/2] selftests/amd-pstate: Fix broken paths to run workloads in amd-pstate-ut

[Swapnil Sapkal]

In selftests/amd-pstate, tbench and gitsource microbenchmarks are used to
compare the performance with different governors. In Current
implementation relative path to run `amd_pstate_tracer.py`
broken. Fixed this by using absolute paths.
Also selftests/amd-pstate uses distro `perf` to capture stats while running
these microbenchmarks. Distro `perf` is not working with upstream
kernel. Fixed this by providing an option to give the perf binary path.

[PATCH 2/2] tools/power/x86/intel_pstate_tracer: Use pygnuplot package for Gnuplot

[Swapnil Sapkal]

In intel_pstate_tracer.py, Gnuplot is used to generate 2D plots.
In current implementation this tracer gives error while importing
the module because Gnuplot is imported from package Gnuplot-py which
does not support python 3.x. Fix this by using pygnuplot package to
import this module.

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.

Presumably this is the one that Swapnil intended:

https://pypi.org/project/py-gnuplot/

It requires python3, so I think if upgrading to this one the script does 
need to be switched to python3.  Besides the shebang, you should also 
use a helper like 2to3 to look for any other changes.

There were 97 hits for 'gnuplot' at pypi.  2 stood out but at least in 
the case of gnuplot based stuff, I think it's worth dropping
a comment that links back to pypi page for the intended package.

Another alternative is to include a 'requirements.txt' file that pip can 
pick up.

Yes, I found that earlier.
For my part of it, I do not want to use any out-of-distro package.

I already did the python 3 patch in January, 2020:
commit e749e09db30c38f1a275945814b0109e530a07b0
tools/power/x86/intel_pstate_tracer: changes for python 3 compatibility

I haven't had any issues since, shebang aside.
