Subject[PATCHSET 0/9] perf tools: Update on filtered entries' percentage output (v7)
Date
Hello,

I added --percentage option to perf report to control display of
percentage of filtered entries.

usage: perf report [<options>]

--percentage <relative|absolute>
how to display percentage of filtered entries

"relative" means it's relative to filtered entries only so that the
sum of shown entries will be always 100%. "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

Any comments are welcome, thanks
