[PATCH 4/5] perf report: Add report.percentage config option

From: Namhyung Kim
Date: Wed Jan 22 2014 - 18:29:58 EST


Add report.percentage option for setting default value of the
symbol_conf.filter_relative. It affects the report output only if a
filter applied.

An user can write .perfconfig file like below to show absolute
percentage of filtered entries by default:

$ cat ~/.perfconfig
[report]
percentage = absolute

And it can be changed through command line:

$ perf report --percentage relative
