Subject: [PATCH 0/5] perf tools: Clean up cpu map handling for system-wide evsel (v2)
Date: Fri, 30 Sep 2022 10:27:09 -0700 [thread overview]
Message-ID: <20220930172714.711616-1-namhyung@kernel.org> (raw)
Hello,
The system-wide evsel has a cpu map for all (online) cpus regardless
of user requested cpus. But the cpu map handling code has some
special case for it and I think we can cleanup the code by making sure
that such a evsel has a proper cpu/thread maps from the beginning.
This patches should not cause any change in the behavior.
Changes from v1:
* use evlist->core.needs_map_propagation field
* add Reviewed-by from Adrian
You can get the code from 'perf/cpumap-update-v2' branch in
git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git
Thanks,
Namhyung
