The problem is, this will cause a _lot_ of counters to be used by default, overloading the PMU quite significantly and reducing precision. The number of hw counters is chosen intentionally the way it is now, so that on common hardware there's no over-commit. As i suggested before, your change does make sense if introduced as extended event specifications to 'perf stat': -e all -e all-sw-counters -e all-hw-counters with regex wildcard support too. Instead, you chose to ignore my feedback and wasted my time by re-sending the same broken patch. If you do such things i'll have to start ignoring you - it is very ineffective for me to repeat every argument and suggestion two or more times and no other contributor does this ... > Remove dead code and some code alignment. Could you please send this separately?
