perf tools: Add hist.percentage config option
Add hist.percentage option for setting default value of the symbol_conf.filter_relative. It affects the output of various perf commands (like perf report, top and diff) only if filter(s) applied. An user can write .perfconfig file like below to show absolute percentage of filtered entries by default: $ cat ~/.perfconfig [hist] percentage = absolute And it can be changed through command line: $ perf report --percentage relative Signed-off-by: Namhyung Kim <namhyung@kernel.org> Link: http://lkml.kernel.org/r/1397145720-8063-6-git-send-email-namhyung@kernel.org Signed-off-by: Jiri Olsa <jolsa@redhat.com>
