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
