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. ...

Doug 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. https://pip.pypa.io/en/stable/reference/requirements-file-format/ > >> Signed-off-by: Swapnil Sapkal <swapnil.sapkal@amd.com> >> --- >> tools/power/x86/amd_pstate_tracer/amd_pstate_trace.py | 1 - >> tools/power/x86/intel_pstate_tracer/intel_pstate_tracer.py | 4 ++-- >> 2 files changed, 2 insertions(+), 3 deletions(-) >> >> diff --git a/tools/power/x86/amd_pstate_tracer/amd_pstate_trace.py b/tools/power/x86/amd_pstate_tracer/amd_pstate_trace.py >> index 2448bb07973f..14f8d81f91de 100755 >> --- a/tools/power/x86/amd_pstate_tracer/amd_pstate_trace.py >> +++ b/tools/power/x86/amd_pstate_tracer/amd_pstate_trace.py >> @@ -27,7 +27,6 @@ import re >> import signal >> import sys >> import getopt >> -import Gnuplot >> from numpy import * >> from decimal import * >> sys.path.append(os.path.join(os.path.dirname(__file__), '../intel_pstate_tracer')) >> diff --git a/tools/power/x86/intel_pstate_tracer/intel_pstate_tracer.py > b/tools/power/x86/intel_pstate_tracer/intel_pstate_tracer.py >> index ec3323100e1a..68412abdd7d4 100755 >> --- a/tools/power/x86/intel_pstate_tracer/intel_pstate_tracer.py >> +++ b/tools/power/x86/intel_pstate_tracer/intel_pstate_tracer.py >> @@ -32,7 +32,7 @@ import re >> import signal >> import sys >> import getopt >> -import Gnuplot >> +from pygnuplot import gnuplot >> from numpy import * >> from decimal import * >> >> @@ -295,7 +295,7 @@ def common_all_gnuplot_settings(output_png): >> def common_gnuplot_settings(): >> """ common gnuplot settings.

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. ...

Hi Mario, I was not aware of the 2to3 helper. Thank you mentioning it. The 2to3 helper only changed one line, which I included in the minimum python version patch I just submitted. > 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. ...

Initially I tried with other packages in prerequisites and it didn't worked for me.

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.
