"absolute" means it retains original value before and after the filter applied. In patch 9/9, I made the "absolute" as default since it makes more sense IMHO. $ perf report -s comm # Overhead Command # ........ ............ # 74.19% cc1 7.61% gcc 6.11% as 4.35% sh 4.14% make 1.13% fixdep ... $ perf report -s comm -c cc1,gcc --percentage absolute # Overhead Command # ........ ............ # 74.19% cc1 7.61% gcc $ perf report -s comm -c cc1,gcc --percentage relative # Overhead Command # ........ ............ # 90.69% cc1 9.31% gcc Note that it has zero effect if no filter was applied. * changes in v7: - rename ->nr_filtered_* to ->nr_non_filtered_* (Arnaldo) - remove an unneeded alignment change (Arnaldo) * changes in v6: - fix a bug in --stdio group report - reuse __hpp__fmt() function in TUI/GTK - add Acked-by from Jiri * changes in v5: - fix 0 samples in relative percent output (Jiri) - factor hists__total_period function (Jiri) - share config parsing code with option parser (Jiri) * changes in v4: - support perf top and perf diff also (Jiri) - add HIST_FILTER__HOST/GUEST (Jiri) - retain both of filtered and total stats (Arnaldo) - add 'F' hotkey on TUI (Jiri) - rename config variable to have "hist." prefix You can get this on the 'perf/percentage-v7' branch in my tree git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git Any comments are welcome, thanks Namhyung Namhyung Kim (9): perf tools: Pass evsel to hpp->header/width functions explicitly perf tools: Count periods of filtered entries separately perf hists: Add support for showing relative percentage perf report: Add --percentage option perf top: Add --percentage option perf diff: Add --percentage option perf tools: Add hist.percentage config option perf ui/tui: Add 'F' hotkey to toggle percentage output perf tools: Show absolute percentage by default tools/perf/Documentation/perf-diff.txt | 21 ++++++++-- tools/perf/Documentation/perf-report.txt | 24 ++++++++--- tools/perf/Documentation/perf-top.txt | 18 +++++++-- tools/perf/builtin-diff.c | 39 ++++++++++++------ tools/perf/builtin-report.c | 24 +++++++++-- tools/perf/builtin-top.c | 2 + tools/perf/ui/browsers/hists.c | 39 ++++++++++++++---- tools/perf/ui/gtk/hists.c | 14 +++---- tools/perf/ui/hist.c | 32 +++++++-------- tools/perf/ui/stdio/hist.c | 5 +-- tools/perf/util/config.c | 4 ++ tools/perf/util/event.c | 22 +++++------ tools/perf/util/hist.c | 68 ++++++++++++++++++++++---------- tools/perf/util/hist.h | 25 +++++++++++- tools/perf/util/symbol.h | 5 ++- 15 files changed, 242 insertions(+), 100 deletions(-) -- 1.7.11.7
