"absolute" means it retains original value before and after the filter applied. In patch 5, 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 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-v4' 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 (8): 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 | 48 +++++++++++++++++++++---- tools/perf/builtin-report.c | 32 +++++++++++++++-- tools/perf/builtin-top.c | 16 +++++++++ tools/perf/ui/browsers/hists.c | 61 ++++++++++++++++++++++++++------ tools/perf/ui/gtk/hists.c | 27 +++++++++----- tools/perf/ui/hist.c | 12 +++++-- tools/perf/util/config.c | 4 +++ tools/perf/util/event.c | 22 ++++++------ tools/perf/util/hist.c | 52 ++++++++++++++++----------- tools/perf/util/hist.h | 15 ++++++++ tools/perf/util/symbol.h | 5 +-- 14 files changed, 278 insertions(+), 79 deletions(-) -- 1.7.11.7 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
