![]() When we filter by column content we may end up with a column that has the same value for all the lines. So remove that column and tell its unique value on the top, as a comment. Example: [acme@doppio pahole]$ perf report --sort comm,dso,symbol -d ./build/libdwarves.so.1.0.0 -C pahole | head -15 # dso: ./build/libdwarves.so.1.0.0 # comm: pahole # Samples: 58409 # # Overhead Symbol # ........ ...... # 20.93% [.] tag__recode_dwarf_type 14.94% [.] namespace__recode_dwarf_types 10.38% [.] cu__table_add_tag 6.69% [.] __die__process_tag 5.05% [.] die__process_function 4.70% [.] list__for_all_tags 3.68% [.] tag__init 3.48% [.] die__create_new_parameter [acme@doppio pahole]$ Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> LKML-Reference: <1247325517-12272-3-git-send-email-acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> |
