Namhyung Kim f58c95e344 perf report: Use hierarchy hpp list on stdio ... Now hpp formats are linked using perf_hpp_list_node when hierarchy is enabled. Use this info to print entries with multiple sort keys in a single hierarchy properly. For example, the below example shows using 4 sort keys with 2 levels. $ perf report --hierarchy -s '{prev_pid,prev_comm},{next_pid,next_comm}' \ --percent-limit 1 -i perf.data.sched ... # Overhead prev_pid+prev_comm / next_pid+next_comm # ........... ....................................... # 22.36% 0 swapper/0 9.48% 17773 transmission-gt 5.25% 109 kworker/0:1H 1.53% 6524 Xephyr 21.39% 17773 transmission-gt 9.52% 0 swapper/0 9.04% 0 swapper/2 1.78% 0 swapper/3 Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1457361308-514-6-git-send-email-namhyung@kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>		2016-03-08 10:11:20 +01:00
