perf ui/stdio: Implement hierarchy output mode
The hierarchy output mode is to group entries for each level so that user can see higher level picture more easily. It also helps to find out which component is most costly. The output will look like below: 15.11% swapper 14.97% [kernel.vmlinux] 0.09% [libahci] 0.05% [iwlwifi] 10.29% irq/33-iwlwifi 6.45% [kernel.vmlinux] 1.41% [mac80211] 1.15% [iwldvm] 1.14% [iwlwifi] 0.14% [cfg80211] 4.81% firefox 3.92% libxul.so 0.34% [kernel.vmlinux] Signed-off-by: Namhyung Kim <namhyung@kernel.org> Acked-by: Pekka Enberg <penberg@kernel.org> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1456326830-30456-10-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
