So, this is the first:
commit 0ab58c405dd7c143a1482cb9414eb0eb9b31d42a (HEAD)
Author: Leo Yan <leo.yan@linaro.org>
Date: Mon Sep 14 19:53:10 2020 +0800
perf tests tsc: Make tsc testing as a common testing
I'll remove it and the ones after that, so the main feature is kept.
I'll retest, and then push to perf/core you can then continue from
there.
Thanks,
- Arnaldo
