From fa25c503dfa203b921199ea42c0046c89f2ed49f Mon Sep 17 00:00:00 2001 From: KOSAKI Motohiro Date: Tue, 24 May 2011 17:11:28 -0700 Subject: mm: per-node vmstat: show proper vmstats commit 2ac390370a ("writeback: add /sys/devices/system/node//vmstat") added vmstat entry. But strangely it only show nr_written and nr_dirtied. # cat /sys/devices/system/node/node20/vmstat nr_written 0 nr_dirtied 0 Of course, It's not adequate. With this patch, the vmstat show all vm stastics as /proc/vmstat. # cat /sys/devices/system/node/node0/vmstat nr_free_pages 899224 nr_inactive_anon 201 nr_active_anon 17380 nr_inactive_file 31572 nr_active_file 28277 nr_unevictable 0 nr_mlock 0 nr_anon_pages 17321 nr_mapped 8640 nr_file_pages 60107 nr_dirty 33 nr_writeback 0 nr_slab_reclaimable 6850 nr_slab_unreclaimable 7604 nr_page_table_pages 3105 nr_kernel_stack 175 nr_unstable 0 nr_bounce 0 nr_vmscan_write 0 nr_writeback_temp 0 nr_isolated_anon 0 nr_isolated_file 0 nr_shmem 260 nr_dirtied 1050 nr_written 938 numa_hit 962872 numa_miss 0 numa_foreign 0 numa_interleave 8617 numa_local 962872 numa_other 0 nr_anon_transparent_hugepages 0 [akpm@linux-foundation.org: no externs in .c files] Signed-off-by: KOSAKI Motohiro Cc: Michael Rubin Cc: Wu Fengguang Acked-by: David Rientjes Cc: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- mm/vmstat.c | 261 ++++++++++++++++++++++++++++++------------------------------ 1 file changed, 132 insertions(+), 129 deletions(-) (limited to 'mm') diff --git a/mm/vmstat.c b/mm/vmstat.c index 897ea9e8823..209546a8bdd 100644 --- a/mm/vmstat.c +++ b/mm/vmstat.c @@ -659,6 +659,138 @@ static void walk_zones_in_node(struct seq_file *m, pg_data_t *pgdat, } #endif +#if defined(CONFIG_PROC_FS) || defined(CONFIG_SYSFS) +#ifdef CONFIG_ZONE_DMA +#define TEXT_FOR_DMA(xx) xx "_dma", +#else +#define TEXT_FOR_DMA(xx) +#endif + +#ifdef CONFIG_ZONE_DMA32 +#define TEXT_FOR_DMA32(xx) xx "_dma32", +#else +#define TEXT_FOR_DMA32(xx) +#endif + +#ifdef CONFIG_HIGHMEM +#define TEXT_FOR_HIGHMEM(xx) xx "_high", +#else +#define TEXT_FOR_HIGHMEM(xx) +#endif + +#define TEXTS_FOR_ZONES(xx) TEXT_FOR_DMA(xx) TEXT_FOR_DMA32(xx) xx "_normal", \ + TEXT_FOR_HIGHMEM(xx) xx "_movable", + +const char * const vmstat_text[] = { + /* Zoned VM counters */ + "nr_free_pages", + "nr_inactive_anon", + "nr_active_anon", + "nr_inactive_file", + "nr_active_file", + "nr_unevictable", + "nr_mlock", + "nr_anon_pages", + "nr_mapped", + "nr_file_pages", + "nr_dirty", + "nr_writeback", + "nr_slab_reclaimable", + "nr_slab_unreclaimable", + "nr_page_table_pages", + "nr_kernel_stack", + "nr_unstable", + "nr_bounce", + "nr_vmscan_write", + "nr_writeback_temp", + "nr_isolated_anon", + "nr_isolated_file", + "nr_shmem", + "nr_dirtied", + "nr_written", + +#ifdef CONFIG_NUMA + "numa_hit", + "numa_miss", + "numa_foreign", + "numa_interleave", + "numa_local", + "numa_other", +#endif + "nr_anon_transparent_hugepages", + "nr_dirty_threshold", + "nr_dirty_background_threshold", + +#ifdef CONFIG_VM_EVENT_COUNTERS + "pgpgin", + "pgpgout", + "pswpin", + "pswpout", + + TEXTS_FOR_ZONES("pgalloc") + + "pgfree", + "pgactivate", + "pgdeactivate", + + "pgfault", + "pgmajfault", + + TEXTS_FOR_ZONES("pgrefill") + TEXTS_FOR_ZONES("pgsteal") + TEXTS_FOR_ZONES("pgscan_kswapd") + TEXTS_FOR_ZONES("pgscan_direct") + +#ifdef CONFIG_NUMA + "zone_reclaim_failed", +#endif + "pginodesteal", + "slabs_scanned", + "kswapd_steal", + "kswapd_inodesteal", + "kswapd_low_wmark_hit_quickly", + "kswapd_high_wmark_hit_quickly", + "kswapd_skip_congestion_wait", + "pageoutrun", + "allocstall", + + "pgrotated", + +#ifdef CONFIG_COMPACTION + "compact_blocks_moved", + "compact_pages_moved", + "compact_pagemigrate_failed", + "compact_stall", + "compact_fail", + "compact_success", +#endif + +#ifdef CONFIG_HUGETLB_PAGE + "htlb_buddy_alloc_success", + "htlb_buddy_alloc_fail", +#endif + "unevictable_pgs_culled", + "unevictable_pgs_scanned", + "unevictable_pgs_rescued", + "unevictable_pgs_mlocked", + "unevictable_pgs_munlocked", + "unevictable_pgs_cleared", + "unevictable_pgs_stranded", + "unevictable_pgs_mlockfreed", + +#ifdef CONFIG_TRANSPARENT_HUGEPAGE + "thp_fault_alloc", + "thp_fault_fallback", + "thp_collapse_alloc", + "thp_collapse_alloc_failed", + "thp_split", +#endif + +#endif /* CONFIG_VM_EVENTS_COUNTERS */ +};
