perf tools: Add support for sorting on the iaddr
Sorting on 'symbol' gives to broad a resolution as it can cover a range of IP address. Use the iaddr instead to get proper sorting on IP addresses. Need to use the 'mem_sort' feature of perf record. New sort option is: symbol_iaddr, header label is 'Code Symbol'. $ perf mem report --stdio -F +symbol_iaddr # Overhead Samples Code Symbol Local Weight # ........ ............ ........................ ............ # 54.08% 1 [k] nmi_handle 192 4.51% 1 [k] finish_task_switch 16 3.66% 1 [.] malloc 13 3.10% 1 [.] __strcoll_l 11 Signed-off-by: Don Zickus <dzickus@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Kan Liang <kan.liang@intel.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1444068369-20978-8-git-send-email-jolsa@kernel.org Signed-off-by: Jiri Olsa <jolsa@kernel.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
