I didn't use oprofile before and always use 'perf', and I am sure it works well with arm a9 pmu hardware on linus tree.
Should we consider oprofile as obsolete in favor of perf?
Are these projects competing to be a default system profiling tool for Linux (at least for ARM platforms)?
Generally, I would advise to migrate to perf. oprofile now uses perf as the backend for ARM anyway; and perf seems to be more functional, more robust and in a better state of maintenance (just my opinion!)
