It does the same as '-p' but it force the deep search of the callchain and looks for the deepest possible match. The -p option searches for the first match of the parent pattern in the callchain. $ perf report -i perf.data.delete -p perf_session__delete -s parent + 99.51% [other] + 0.46% perf_session__delete_dead_threads + 0.03% perf_session__delete + 0.00% perf_session__delete_threads so we got multiple 'different' matches instancies, while they all belong under perf_session__delete function: $ perf report -i perf.data.delete -P perf_session__delete -s parent + 99.51% [other] + 0.49% perf_session__delete NOTE the 'p' vs 'P' difference in above commands above.
