[PATCH v1 1/2] perf test: Add an 'import perf' test shell script

[Ian Rogers]

The 'import perf' test needs to set up a path to the python module as
well as to know the python command to invoke. These are hard coded at
build time to be build a directory and the python used in the build,
which is less than desirable. Avoid the hard coded values by reusing
the existing shell script python setup and determine a potential built
python module via the path of the perf executable.

Aside from avoiding hard coded build directories, this also looks much cleaner to me.

There is another patch in this area to make it work, right?

After applying this one I get a failure, only when I set PYTHONPATH it
works:

⬢ [acme@toolbx perf-tools-next]$ export PYTHONPATH=/tmp/build/perf-tools-next/python_ext_build/lib/
⬢ [acme@toolbx perf-tools-next]$ perf test -v pytho
Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
 88: 'import perf' in python                                         : Ok
⬢ [acme@toolbx perf-tools-next]$

Hmm.. if you are running from the install directory then I guess the
assumption should be that the install bin directory is in the PATH,
lib in LD_LIBRARY_PATH and PYTHONPATH set up for the directory too? We
could have the script look for a python module going from ..../bin to
..../lib and fix the PYTHONPATH for you. Wdyyt?

Thanks,
Ian

I reported it more in the sense that something that was working before
stopped working but having not yet tried to see why it stopped working.
