When in report group mode (perf report --group) with option --show-total-period, display period values for all group members.
Currently only the group leader period counts are shown. Example of new output: $ perf report --group --show-total-period --stdio ... # Samples: 76 of event 'anon group { cycles, cache-misses }' # Event count (approx.): 32249096 # # Overhead Period Command Shared Object Symbol # ................ ........................ ....... ................. ............................. # 18.45% 11.67% 5949678 333 ls [kernel.kallsyms] [k] __lock_acquire 16.49% 11.39% 5317432 325 ls [kernel.kallsyms] [k] native_sched_clock 8.55% 15.42% 2757064 440 ls [kernel.kallsyms] [k] lock_acquire 8.31% 12.58% 2680708 359 ls [kernel.kallsyms] [k] clear_page_c ...
