Prev: [PATCH 4/7] vmscan: convert direct reclaim tracepoint to DEFINE_EVENT
Next: [PATCH 3/7] memcg: nid and zid can be calculated from zone
From: KOSAKI Motohiro on 16 Jul 2010 06:20 Recently, Mel Gorman added some vmscan tracepoint. but they can't trace memcg. So, This patch series does. following three patches are nit fix and cleanups. memcg: sc.nr_to_reclaim should be initialized memcg: mem_cgroup_shrink_node_zone() doesn't need sc.nodemask memcg: nid and zid can be calculated from zone following four patches are tracepoint conversion and adding memcg tracepoints. vmscan: convert direct reclaim tracepoint to DEFINE_EVENT memcg, vmscan: add memcg reclaim tracepoint vmscan: convert mm_vmscan_lru_isolate to DEFINE_EVENT memcg, vmscan: add mm_vmscan_memcg_isolate tracepoint diffstat ================ include/linux/memcontrol.h | 6 ++-- include/linux/mmzone.h | 5 +++ include/linux/swap.h | 3 +- include/trace/events/vmscan.h | 79 +++++++++++++++++++++++++++++++++++++++-- mm/memcontrol.c | 15 +++++--- mm/vmscan.c | 35 ++++++++++++------ 6 files changed, 118 insertions(+), 25 deletions(-) Sameple output is here. ========================= dd-1851 [001] 158.837763: mm_vmscan_memcg_reclaim_begin: order=0 may_writepage=1 gfp_flags=GFP_HIGHUSER_MOVABLE dd-1851 [001] 158.837783: mm_vmscan_memcg_isolate: isolate_mode=0 order=0 nr_requested=32 nr_scanned=32 nr_taken=32 contig_taken=0 contig_dirty=0 contig_failed=0 dd-1851 [001] 158.837860: mm_vmscan_memcg_reclaim_end: nr_reclaimed=32 (...) dd-1970 [000] 266.608235: mm_vmscan_wakeup_kswapd: nid=0 zid=1 order=0 dd-1970 [000] 266.608239: mm_vmscan_wakeup_kswapd: nid=1 zid=1 order=0 dd-1970 [000] 266.608248: mm_vmscan_wakeup_kswapd: nid=2 zid=1 order=0 kswapd1-348 [001] 266.608254: mm_vmscan_kswapd_wake: nid=1 order=0 dd-1970 [000] 266.608254: mm_vmscan_wakeup_kswapd: nid=3 zid=1 order=0 kswapd3-350 [000] 266.608266: mm_vmscan_kswapd_wake: nid=3 order=0 (...) kswapd0-347 [001] 267.328891: mm_vmscan_memcg_softlimit_reclaim_begin: order=0 may_writepage=1 gfp_flags=GFP_HIGHUSER_MOVABLE kswapd0-347 [001] 267.328897: mm_vmscan_memcg_isolate: isolate_mode=0 order=0 nr_requested=32 nr_scanned=32 nr_taken=32 contig_taken=0 contig_dirty=0 contig_failed=0 kswapd0-347 [001] 267.328915: mm_vmscan_memcg_isolate: isolate_mode=0 order=0 nr_requested=32 nr_scanned=32 nr_taken=32 contig_taken=0 contig_dirty=0 contig_failed=0 kswapd0-347 [001] 267.328989: mm_vmscan_memcg_softlimit_reclaim_end: nr_reclaimed=32 kswapd0-347 [001] 267.329019: mm_vmscan_lru_isolate: isolate_mode=1 order=0 nr_requested=32 nr_scanned=32 nr_taken=32 contig_taken=0 contig_dirty=0 contig_failed=0 kswapd0-347 [001] 267.330562: mm_vmscan_lru_isolate: isolate_mode=1 order=0 nr_requested=32 nr_scanned=32 nr_taken=32 contig_taken=0 contig_dirty=0 contig_failed=0 (...) kswapd2-349 [001] 267.407081: mm_vmscan_kswapd_sleep: nid=2 kswapd3-350 [001] 267.408077: mm_vmscan_kswapd_sleep: nid=3 kswapd1-348 [000] 267.427858: mm_vmscan_kswapd_sleep: nid=1 kswapd0-347 [001] 267.430064: mm_vmscan_kswapd_sleep: nid=0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
