Subject: [VSP-Tests PATCH 0/3] Run as user, and python3 support
Date: Wed, 16 Sep 2020 15:42:59 +0100 [thread overview]
Message-ID: <20200916144302.1483470-1-kieran.bingham@ideasonboard.com> (raw)
My development target now runs as a user, rather than root and fails to
obtain timestamps through the /proc/timer_list which requires root
access, and generates a warning on every log output.
Whilst not fatal, this can be fixed by using a c-based implementation to
read the monotonic timestamps without parsing proc manually with awk.
This has the extra advantage of not spawning extra processes for every
line that is logged, and simplifies the timestamp handling.
Furthermore, python2 is no longer available on my platforms so the
gen-lut.py script is updated to run as python3.
I am aware that there is a second python2 tool in this repository, for
converting histograms, however I have not yet identified what files this
process so I have not completed the python3 migration for that file yet.
If someone wants to complete this, I have the initial conversion, or
alternatively - if someone has a set of appropriate histograms to give
me I can update and validate the tool myself.
