From: Namhyung Kim <namhyung@kernel.org>
When --hierarchy option is used, each entry has its own hpp_list to show
the result. But it missed to update width of each column.
Before:
- 46.29% 48.12% netctl-auto
+ 31.44% 29.25% [kernel.vmlinux]
+ 8.52% 11.55% libc-2.22.so
+ 5.19% 6.91% bash
+ 10.75% 11.83% wpa_cli
+ 8.25% 2.23% swapper
+ 6.45% 5.40% tr
+ 4.81% 8.09% awk
+ 4.15% 2.85% firefox
+ 3.86% 2.53% sh
After:
- 46.29% 48.12% netctl-auto
+ 31.44% 29.25% [kernel.vmlinux]
+ 8.52% 11.55% libc-2.22.so
+ 5.19% 6.91% bash
+ 10.75% 11.83% wpa_cli
+ 8.25% 2.23% swapper
+ 6.45% 5.40% tr
+ 4.81% 8.09% awk
+ 4.15% 2.85% firefox
+ 3.86% 2.53% sh
Committer note:
Full testing instructions:
1) Record with an event group:
$ perf record -e '{cycles,instructions}' make -j4
2) Use report in hierarchy mode, to get a few expanded trees on
the same screen, use --percent-limit:
$ perf report --hierarchy --percent-limit 0.5
Samples: 103K of event 'anon group { cycles:u, instructions:u }',
Event count (approx.): 57317631725
