So we also invert the way the lists of pages for migration are\nbuild.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nLooks-ok-to: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "fcab6f351305029fc5e3c632209d45cae57e4835", "tree": "21a84b35d172b63a47421190af83eb12c006a8e2", "parents": [ "1dd31b6c89611ee91c0ff309c8733c0af61579e8" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Feb 20 18:28:10 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Feb 20 20:00:11 2006 -0800" }, "message": "[PATCH] mm/mempolicy.c: fix \u0027if ();\u0027 typo\n\n[akpm; it happens that the code was still correct, only inefficient ]\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Christoph Lameter \u003cchristoph@lameter.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a9c930bac163c5e616ca0ba9378e7dc746c93227", "tree": "58ff339858cee3a87893c094561eb72381044a08", "parents": [ "c255d844dd73616f23e4b4733edcc2e5fa4042b2" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Mon Feb 20 18:27:59 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Feb 20 20:00:10 2006 -0800" }, "message": "[PATCH] Fix units in mbind check\n\nmaxnode is a bit index and can\u0027t be directly compared against a byte length\nlike PAGE_SIZE\n\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Chris Wright \u003cchrisw@sous-sol.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "636f13c174dd7c84a437d3c3e8fa66f03f7fda63", "tree": "2dd28d7729a52655eb4e155af620c5afdda85a8a", "parents": [ "74910e6c7dc7471b286a883c1a7af70483ffd2ba" ], "author": { "name": "Chris Wright", "email": "chrisw@sous-sol.org", "time": "Fri Feb 17 13:59:36 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Feb 17 14:09:22 2006 -0800" }, "message": "[PATCH] sys_mbind sanity checking\n\nMake sure maxnodes is safe size before calculating nlongs in\nget_nodes().\n\nSigned-off-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "dd942ae331425812930cd01766178b7e28e65f2d", "tree": "b513bcfa00c1fc0f78e06b7f4c8d999275b64dfb", "parents": [ "759b650f54ed13e9b3d6c064c763a72ee09c74dd" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Fri Feb 17 01:39:16 2006 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Feb 17 08:18:14 2006 -0800" }, "message": "[PATCH] Handle all and empty zones when setting up custom zonelists for mbind\n\nThe memory allocator doesn\u0027t like empty zones (which have an\nuninitialized freelist), so a x86-64 system with a node fully\nin GFP_DMA32 only would crash on mbind.\n\nFix that up by putting all possible zones as fallback into the zonelist\nand skipping the empty ones.\n\nIn fact the code always enough allocated space for all zones,\nbut only used it for the highest.

This means that memory policies may control the behavior of\nalloc_pages(). During bootup the memory policy is set to MPOL_INTERLEAVE\nresulting in the spreading out of allocations during bootup over all\navailable nodes. The slab allocator in 2.6.13 has only a single list of\nslab pages. As a result the per cpu slab cache and the spinlock controlled\npage lists may contain slab entries from off node memory. The slab\nallocator in 2.6.13 makes no effort to discern the locality of an entry on\nits lists.\n\nThe NUMA aware slab allocator in 2.6.14 controls locality of the slab pages\nexplicitly by calling alloc_pages_node(). The NUMA slab allocator manages\nslab entries by having lists of available slab pages for each node. The\nper cpu slab cache can only contain slab entries associated with the node\nlocal to the processor. This guarantees that the default allocation mode\nof the slab allocator always assigns local memory if available.\n\nSetting MPOL_INTERLEAVE as a default policy during bootup has no effect\nanymore. In 2.6.14 all node unspecific slab allocations are performed on\nthe boot processor. This means that most of key data structures are\nallocated on one node. Most processors will have to refer to these\nstructures making the boot node a potential bottleneck. This may reduce\nperformance and cause unnecessary memory pressure on the boot node.\n\nThis patch implements NUMA policies in the slab layer. There is the need\nof explicit application of NUMA memory policies by the slab allcator itself\nsince the NUMA slab allocator does no longer let the page_allocator control\nlocality.\n\nThe check for policies is made directly at the beginning of __cache_alloc\nusing current-\u003emempolicy. The memory policy is already frequently checked\nby the page allocator (alloc_page_vma() and alloc_page_current()). So it\nis highly likely that the cacheline is present. For MPOL_INTERLEAVE\nkmalloc() will spread out each request to one node after another so that an\nequal distribution of allocations can be obtained during bootup.\n\nIt is not possible to push the policy check to lower layers of the NUMA\nslab allocator since the per cpu caches are now only containing slab\nentries from the current node. If the policy says that the local node is\nnot to be preferred or forbidden then there is no point in checking the\nslab cache or local list of slab pages. The allocation better be directed\nimmediately to the lists containing slab entries for the allowed set of\nnodes.\n\nThis way of applying policy also fixes another strange behavior in 2.6.13.\nalloc_pages() is controlled by the memory allocation policy of the current\nprocess. It could therefore be that one process is running with\nMPOL_INTERLEAVE and would f.e. obtain a new page following that policy\nsince no slab entries are in the lists anymore. A page can typically be\nused for multiple slab entries but lets say that the current process is\nonly using one. The other entries are then added to the slab lists. These\nare now non local entries in the slab lists despite of the possible\navailability of local pages that would provide faster access and increase\nthe performance of the application.\n\nAnother process without MPOL_INTERLEAVE may now run and expect a local slab\nentry from kmalloc(). However, there are still these free slab entries\nfrom the off node page obtained from the other process via MPOL_INTERLEAVE\nin the cache. The process will then get an off node slab entry although\nother slab entries may be available that are local to that process. This\nmeans that the policy if one process may contaminate the locality of the\nslab caches for other processes.\n\nThis patch in effect insures that a per process policy is followed for the\nallocation of slab entries and that there cannot be a memory policy\ninfluence from one process to another. A process with default policy will\nalways get a local slab entry if one is available. And the process using\nmemory policies will get its memory arranged as requested. Off-node slab\nallocation will require the use of spinlocks and will make the use of per\ncpu caches not possible. A process using memory policies to redirect\nallocations offnode will have to cope with additional lock overhead in\naddition to the latency added by the need to access a remote slab entry.\n\nChanges V1-\u003eV2\n- Remove #ifdef CONFIG_NUMA by moving forward declaration into\n prior #ifdef CONFIG_NUMA section.\n\n- Give the function determining the node number to use a saner\n name.\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" }, { "commit": "fc3012896337c83a056c496d7cfb0072e1591181", "tree": "5b774e59ba982fd4330eb96abace9cda9d744b0f", "parents": [ "053837fce7aa79025ed57656855df09f80175527" ], "author": { "name": "Christoph Lameter", "email": "clameter@engr.sgi.com", "time": "Wed Jan 18 17:42:29 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Jan 18 19:20:17 2006 -0800" }, "message": "[PATCH] Simplify migrate_page_add\n\nSimplify migrate_page_add after feedback from Hugh.

The kernel maintains\ninternal state for each mempolicy, tracking what nodes are used for the\nMPOL_INTERLEAVE, MPOL_BIND or MPOL_PREFERRED policies.\n\nWhen a tasks cpuset memory placement changes, whether because the cpuset\nchanged, or because the task was attached to a different cpuset, then the\ntasks mempolicies have to be rebound to the new cpuset placement, so as to\npreserve the cpuset-relative numbering of the nodes in that policy.\n\nAn earlier fix handled such mempolicy rebinding for mempolicies attached to a\ntask.\n\nThis fix rebinds mempolicies attached to vma\u0027s (address ranges in a tasks\naddress space.) Due to the need to hold the task-\u003emm-\u003emmap_sem semaphore while\nupdating vma\u0027s, the rebinding of vma mempolicies has to be done when the\ncpuset memory placement is changed, at which time mmap_sem can be safely\nacquired. The tasks mempolicy is rebound later, when the task next attempts\nto allocate memory and notices that its task-\u003ecpuset_mems_generation is\nout-of-date with its cpusets mems_generation.\n\nBecause walking the tasklist to find all tasks attached to a changing cpuset\nrequires holding tasklist_lock, a spinlock, one cannot update the vma\u0027s of the\naffected tasks while doing the tasklist scan. In general, one cannot acquire\na semaphore (which can sleep) while already holding a spinlock (such as\ntasklist_lock). So a list of mm references has to be built up during the\ntasklist scan, then the tasklist lock dropped, then for each mm, its mmap_sem\nacquired, and the vma\u0027s in that mm rebound.\n\nOnce the tasklist lock is dropped, affected tasks may fork new tasks, before\ntheir mm\u0027s are rebound.

It does so within the context of the task,\nwithout any need to support low level external mempolicy manipulation.\n\nIf a system is not using cpusets, or if running on a system with just the\nroot (all-encompassing) cpuset, then this remap is a no-op. Only when a\ntask is moved between cpusets, or a cpusets memory placement is changed\ndoes the following apply. Otherwise, the main routine below,\nrebind_policy() is not even called.\n\nWhen mixing cpusets, scheduler affinity, and NUMA mempolicies, the\nessential role of cpusets is to place jobs (several related tasks) on a set\nof CPUs and Memory Nodes, the essential role of sched_setaffinity is to\nmanage a jobs processor placement within its allowed cpuset, and the\nessential role of NUMA mempolicy (mbind, set_mempolicy) is to manage a jobs\nmemory placement within its allowed cpuset.\n\nHowever, CPU affinity and NUMA memory placement are managed within the\nkernel using absolute system wide numbering, not cpuset relative numbering.\n\nThis is ok until a job is migrated to a different cpuset, or what\u0027s the\nsame, a jobs cpuset is moved to different CPUs and Memory Nodes.\n\nThen the CPU affinity and NUMA memory placement of the tasks in the job\nneed to be updated, to preserve their cpuset-relative position. This can\nbe done for CPU affinity using sched_setaffinity() from user code, as one\ntask can modify anothers CPU affinity. This cannot be done from an\nexternal task for NUMA memory placement, as that can only be modified in\nthe context of the task using it.\n\nHowever, it easy enough to remap a tasks NUMA mempolicy automatically when\na task is migrated, using the existing cpuset mechanism to trigger a\nrefresh of a tasks memory placement after its cpuset has changed. All that\nis needed is the old and new nodemask, and notice to the task that it needs\nto rebind its mempolicy. The tasks mems_allowed has the old mask, the\ntasks cpuset has the new mask, and the existing\ncpuset_update_current_mems_allowed() mechanism provides the notice. The\nbitmap/cpumask/nodemask remap operators provide the cpuset relative\ncalculations.\n\nThis patch leaves open a couple of issues:\n\n 1) Updating vma and shmfs/tmpfs/hugetlbfs memory policies:\n\n These mempolicies may reference nodes outside of those allowed to\n the current task by its cpuset. Tasks are migrated as part of jobs,\n which reside on what might be several cpusets in a subtree. When such\n a job is migrated, all NUMA memory policy references to nodes within\n that cpuset subtree should be translated, and references to any nodes\n outside that subtree should be left untouched. A future patch will\n provide the cpuset mechanism needed to mark such subtrees. With that\n patch, we will be able to correctly migrate these other memory policies\n across a job migration.\n\n 2) Updating cpuset, affinity and memory policies in user space:\n\n This is harder. Any placement state stored in user space using\n system-wide numbering will be invalidated across a migration. More\n work will be required to provide user code with a migration-safe means\n to manage its cpuset relative placement, while preserving the current\n API\u0027s that pass system wide numbers, not cpuset relative numbers across\n the kernel-user boundary.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5fcbb23050936d69de8087d4b311eaf55cb42740", "tree": "10d14ca6927bc1bfa4bca4d206d2e1039f6cbf03", "parents": [ "8bccd85ffbaf8ff1448d1235fa6594e207695531" ], "author": { "name": "Christoph Lameter", "email": "clameter@engr.sgi.com", "time": "Sat Oct 29 18:17:00 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Oct 29 21:40:45 2005 -0700" }, "message": "[PATCH] Remove policy contextualization from mbind\n\nPolicy contextualization is only useful for task based policies and not for\nvma based policies.

This means that the operations to manage pages on remote zone can be\ndone with information available locally.\n\nWe play a macro trick so that non-NUMA pmachines avoid the additional\npointer chase on the page allocator fastpath.\n\nAIM7 benchmark on a 32 CPU SGI Altix\n\nw/o patches:\nTasks jobs/min jti jobs/min/task real cpu\n 1 484.68 100 484.6769 12.01 1.97 Fri Mar 25 11:01:42 2005\n 100 27140.46 89 271.4046 21.44 148.71 Fri Mar 25 11:02:04 2005\n 200 30792.02 82 153.9601 37.80 296.72 Fri Mar 25 11:02:42 2005\n 300 32209.27 81 107.3642 54.21 451.34 Fri Mar 25 11:03:37 2005\n 400 34962.83 78 87.4071 66.59 588.97 Fri Mar 25 11:04:44 2005\n 500 31676.92 75 63.3538 91.87 742.71 Fri Mar 25 11:06:16 2005\n 600 36032.69 73 60.0545 96.91 885.44 Fri Mar 25 11:07:54 2005\n 700 35540.43 77 50.7720 114.63 1024.28 Fri Mar 25 11:09:49 2005\n 800 33906.70 74 42.3834 137.32 1181.65 Fri Mar 25 11:12:06 2005\n 900 34120.67 73 37.9119 153.51 1325.26 Fri Mar 25 11:14:41 2005\n 1000 34802.37 74 34.8024 167.23 1465.26 Fri Mar 25 11:17:28 2005\n\nwith slab API changes and pageset patch:\n\nTasks jobs/min jti jobs/min/task real cpu\n 1 485.00 100 485.0000 12.00 1.96 Fri Mar 25 11:46:18 2005\n 100 28000.96 89 280.0096 20.79 150.45 Fri Mar 25 11:46:39 2005\n 200 32285.80 79 161.4290 36.05 293.37 Fri Mar 25 11:47:16 2005\n 300 40424.15 84 134.7472 43.19 438.42 Fri Mar 25 11:47:59 2005\n 400 39155.01 79 97.8875 59.46 590.05 Fri Mar 25 11:48:59 2005\n 500 37881.25 82 75.7625 76.82 730.19 Fri Mar 25 11:50:16 2005\n 600 39083.14 78 65.1386 89.35 872.79 Fri Mar 25 11:51:46 2005\n 700 38627.83 77 55.1826 105.47 1022.46 Fri Mar 25 11:53:32 2005\n 800 39631.94 78 49.5399 117.48 1169.94 Fri Mar 25 11:55:30 2005\n 900 36903.70 79 41.0041 141.94 1310.78 Fri Mar 25 11:57:53 2005\n 1000 36201.23 77 36.2012 160.77 1458.31 Fri Mar 25 12:00:34 2005\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Shobhit Dayal \u003cshobhit@calsoftinc.com\u003e\nSigned-off-by: Shai Fultheim \u003cShai@Scalex86.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "01424961e621737c638e489b6a0b5e6602b02612", "tree": "ae51380febe42e40d09375648b0d379325b905a7", "parents": [ "bc86120a85ebf553180946e8854d1993f074e9f5" ], "author": { "name": "Al Viro", "email": "viro@www.linux.org.uk", "time": "Sun Apr 24 12:28:34 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sun Apr 24 12:28:34 2005 -0700" }, "message": "[PATCH] mempolicy.c GFP fix\n\nzonelist_policy() forgot to mask non-zone bits from gfp when comparing\nzone number with policy_zone. \n\nACKed-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Al Viro \u003cviro@parcelfarce.linux.theplanet.co.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
