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 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.
I only added the option to perf report for now. If it looks good to
you I'll add it to perf top too.
Any comments are welcome, thanks
