Namhyung Kim 2a7ef02c9c perf kmem: Add --live option for current allocation stat ... Currently 'perf kmem stat --page' shows total (page) allocation stat by default, but sometimes one might want to see live (total alloc-only) requests/pages only. The new --live option does this by subtracting freed allocation from the stat. E.g.: # perf kmem stat --page SUMMARY (page allocator) ======================== Total allocation requests : 988,858 [ 4,045,368 KB ] Total free requests : 886,484 [ 3,624,996 KB ] Total alloc+freed requests : 885,969 [ 3,622,628 KB ] Total alloc-only requests : 102,889 [ 422,740 KB ] Total free-only requests : 515 [ 2,368 KB ] Total allocation failures : 0 [ 0 KB ] Order Unmovable Reclaimable Movable Reserved CMA/Isolated ----- ------------ ------------ ------------ ------------ ------------ 0 172,173 3,083 806,686 . . 1 284 . . . . 2 6,124 58 . . . 3 114 335 . . . 4 . . . . . 5 . . . . . 6 . . . . . 7 . . . . . 8 . . . . . 9 . . 1 . . 10 . . . . . # perf kmem stat --page --live SUMMARY (page allocator) ======================== Total allocation requests : 988,858 [ 4,045,368 KB ] Total free requests : 886,484 [ 3,624,996 KB ] Total alloc+freed requests : 885,969 [ 3,622,628 KB ] Total alloc-only requests : 102,889 [ 422,740 KB ] Total free-only requests : 515 [ 2,368 KB ] Total allocation failures : 0 [ 0 KB ] Order Unmovable Reclaimable Movable Reserved CMA/Isolated ----- ------------ ------------ ------------ ------------ ------------ 0 2,214 3,025 97,156 . . 1 59 . . . . 2 19 58 . . . 3 23 335 . . . 4 . . . . . 5 . . . . . 6 . . . . . 7 . . . . . 8 . . . . . 9 . . . . . 10 . . . . . # Signed-off-by: Namhyung Kim <namhyung@kernel.org> Acked-by: Pekka Enberg <penberg@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Joonsoo Kim <js1304@gmail.com> Cc: Minchan Kim <minchan@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: linux-mm@kvack.org Link: http://lkml.kernel.org/r/1429592107-1807-4-git-send-email-namhyung@kernel.org [ Added examples to the changeset log ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2015-05-04 13:34:47 -03:00
