      "message": "Move remote node draining out of slab allocators\n\nCurrently the slab allocators contain callbacks into the page allocator to\nperform the draining of pagesets on remote nodes.  This requires SLUB to have\na whole subsystem in order to be compatible with SLAB.  Moving node draining\nout of the slab allocators avoids a section of code in SLUB.\n\nMove the node draining so that is is done when the vm statistics are updated.\nAt that point we are already touching all the cachelines with the pagesets of\na processor.\n\nAdd a expire counter there.  If we have to update per zone or global vm\nstatistics then assume that the pageset will require subsequent draining.\n\nThe expire counter will be decremented on each vm stats update pass until it\nreaches zero.  Then we will drain one batch from the pageset.  The draining\nwill cause vm counter updates which will then cause another expiration until\nthe pcp is empty.  So we will drain a batch every 3 seconds.\n\nNote that remote node draining is a somewhat esoteric feature that is required\non large NUMA systems because otherwise significant portions of system memory\ncan become trapped in pcp queues.  The number of pcp is determined by the\nnumber of processors and nodes in a system.  A system with 4 processors and 2\nnodes has 8 pcps which is okay.  But a system with 1024 processors and 512\nnodes has 512k pcps with a high potential for large amount of memory being\ncaught in them.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

These are two different domains\nof values.\n\nFor some reason seemed to work before the zone reduction patchset (It\ndefinitely works on SGI boxes since we just have one zone and the check\ncannot fail).\n\nWith the zone reduction patchset this check definitely fails on systems\nwith two zones if the system actually has memory in both zones.\n\nThis is because ZONE_NORMAL is selected using no __GFP flag at\nall and thus gfp_zone(gfpmask) \u003d\u003d 0. ZONE_DMA is selected when __GFP_DMA\nis set. __GFP_DMA is 0x01.  So gfp_zone(gfpmask) \u003d\u003d 1.\n\npolicy_zone is set to ZONE_NORMAL (\u003d\u003d1) if ZONE_NORMAL and ZONE_DMA are\npopulated.\n\nFor ZONE_NORMAL gfp_zone(\u003cno _GFP_DMA\u003e) yields 0 which is \u003c\npolicy_zone(ZONE_NORMAL) and so policy is not applied to regular memory\nallocations!\n\nInstead gfp_zone(__GFP_DMA) \u003d\u003d 1 which results in policy being applied\nto DMA allocations!\n\nWhat we realy want in that place is to establish the highest allowable\nzone for a given gfp_mask. If the highest zone is higher or equal to the\npolicy_zone then memory policies need to be applied. We have such\na highest_zone() function in page_alloc.c.\n\nSo move the highest_zone() function from mm/page_alloc.c into\ninclude/linux/gfp.h.  On the way we simplify the function and use the new\nzone_type that was also introduced with the zone reduction patchset plus we\nalso specify the right type for the gfp flags parameter.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] slab: Node rotor for freeing alien caches and remote per cpu pages.\n\nThe cache reaper currently tries to free all alien caches and all remote\nper cpu pages in each pass of cache_reap.  For a machines with large number\nof nodes (such as Altix) this may lead to sporadic delays of around ~10ms.\nInterrupts are disabled while reclaiming creating unacceptable delays.\n\nThis patch changes that behavior by adding a per cpu reap_node variable.\nInstead of attempting to free all caches, we free only one alien cache and\nthe per cpu pages from one remote node.  That reduces the time spend in\ncache_reap.  However, doing so will lengthen the time it takes to\ncompletely drain all remote per cpu pagesets and all alien caches.  The\ntime needed will grow with the number of nodes in the system.  All caches\nare drained when they overflow their respective capacity.  So the drawback\nhere is only that a bit of memory may be wasted for awhile longer.\n\nDetails:\n\n1. Rename drain_remote_pages to drain_node_pages to allow the specification\n   of the node to drain of pcp pages.\n\n2. Add additional functions init_reap_node, next_reap_node for NUMA\n   that manage a per cpu reap_node counter.\n\n3. Add a reap_alien function that reaps only from the current reap_node.\n\nFor us this seems to be a critical issue.  Holdoffs of an average of ~7ms\ncause some HPC benchmarks to slow down significantly.  F.e.  NAS parallel\nslows down dramatically.  NAS parallel has a 12-16 seconds runtime w/o rotor\ncompared to 5.8 secs with the rotor patches.  It gets down to 5.05 secs with\nthe additional interrupt holdoff reductions.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] x86_64: Add 4GB DMA32 zone\n\nAdd a new 4GB GFP_DMA32 zone between the GFP_DMA and GFP_NORMAL zones.\n\nAs a bit of historical background: when the x86-64 port\nwas originally designed we had some discussion if we should\nuse a 16MB DMA zone like i386 or a 4GB DMA zone like IA64 or\nboth. Both was ruled out at this point because it was in early\n2.4 when VM is still quite shakey and had bad troubles even\ndealing with one DMA zone.  We settled on the 16MB DMA zone mainly\nbecause we worried about older soundcards and the floppy.\n\nBut this has always caused problems since then because\ndevice drivers had trouble getting enough DMA able memory. These days\nthe VM works much better and the wide use of NUMA has proven\nit can deal with many zones successfully.\n\nSo this patch adds both zones.\n\nThis helps drivers who need a lot of memory below 4GB because\ntheir hardware is not accessing more (graphic drivers - proprietary\nand free ones, video frame buffer drivers, sound drivers etc.).\nPreviously they could only use IOMMU+16MB GFP_DMA, which\nwas not enough memory.\n\nAnother common problem is that hardware who has full memory\naddressing for \u003e4GB misses it for some control structures in memory\n(like transmit rings or other metadata).  They tended to allocate memory\nin the 16MB GFP_DMA or the IOMMU/swiotlb then using pci_alloc_consistent,\nbut that can tie up a lot of precious 16MB GFPDMA/IOMMU/swiotlb memory\n(even on AMD systems the IOMMU tends to be quite small) especially if you have\nmany devices.  With the new zone pci_alloc_consistent can just put\nthis stuff into memory below 4GB which works better.\n\nOne argument was still if the zone should be 4GB or 2GB. The main\nmotivation for 2GB would be an unnamed not so unpopular hardware\nraid controller (mostly found in older machines from a particular four letter\ncompany) who has a strange 2GB restriction in firmware. But\nthat one works ok with swiotlb/IOMMU anyways, so it doesn\u0027t really\nneed GFP_DMA32. I chose 4GB to be compatible with IA64 and because\nit seems to be the most common restriction.\n\nThe new zone is so far added only for x86-64.\n\nFor other architectures who don\u0027t set up this\nnew zone nothing changes. Architectures can set a compatibility\ndefine in Kconfig CONFIG_DMA_IS_DMA32 that will define GFP_DMA32\nas GFP_DMA. Otherwise it\u0027s a nop because on 32bit architectures\nit\u0027s normally not needed because GFP_NORMAL (\u003d0) is DMA able\nenough.\n\nOne problem is still that GFP_DMA means different things on different\narchitectures. e.g. some drivers used to have #ifdef ia64  use GFP_DMA\n(trusting it to be 4GB) #elif __x86_64__ (use other hacks like\nthe swiotlb because 16MB is not enough) ... . This was quite\nugly and is now obsolete.\n\nThese should be now converted to use GFP_DMA32 unconditionally. I haven\u0027t done\nthis yet. Or best only use pci_alloc_consistent/dma_alloc_coherent\nwhich will use GFP_DMA32 transparently.\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] Periodically drain non local pagesets\n\nThe pageset array can potentially acquire a huge amount of memory on large\nNUMA systems.  F.e.  on a system with 512 processors and 256 nodes there\nwill be 256*512 pagesets.  If each pageset only holds 5 pages then we are\ntalking about 655360 pages.With a 16K page size on IA64 this results in\npotentially 10 Gigabytes of memory being trapped in pagesets.  The typical\ncases are much less for smaller systems but there is still the potential of\nmemory being trapped in off node pagesets.  Off node memory may be rarely\nused if local memory is available and so we may potentially have memory in\nseldom used pagesets without this patch.\n\nThe slab allocator flushes its per cpu caches every 2 seconds.  The\nfollowing patch flushes the off node pageset caches in the same way by\ntying into the slab flush.\n\nThe patch also changes /proc/zoneinfo to include the number of pages\ncurrently in each pageset.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] VM: add __GFP_NORECLAIM\n\nWhen using the early zone reclaim, it was noticed that allocating new pages\nthat should be spread across the whole system caused eviction of local pages.\n\nThis adds a new GFP flag to prevent early reclaim from happening during\ncertain allocation attempts.  The example that is implemented here is for page\ncache pages.  We want page cache pages to be spread across the whole system,\nand we don\u0027t want page cache pages to evict other pages to get local memory.\n\nSigned-off-by:  Martin Hicks \u003cmort@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
