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": "fb5eeeee44edb248b4837416966f19731f497f79", "tree": "f947a4dcf103f55d526bb5c71f69b657d8f22e61", "parents": [ "28a42b9ea7e42e1efb02cc2dcacba0b6af234e1b" ], "author": { "name": "Paul Jackson", "email": "pj@sgi.com", "time": "Sun Oct 30 15:02:33 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 30 17:37:21 2005 -0800" }, "message": "[PATCH] cpusets: bitmap and mask remap operators\n\nIn the forthcoming task migration support, a key calculation will be\nmapping cpu and node numbers from the old set to the new set while\npreserving cpuset-relative offset.\n\nFor example, if a task and its pages on nodes 8-11 are being migrated to\nnodes 24-27, then pages on node 9 (the 2nd node in the old set) should be\nmoved to node 25 (the 2nd node in the new set.)\n\nAs with other bitmap operations, the proper way to code this is to provide\nthe underlying calculation in lib/bitmap.c, and then to provide the usual\ncpumask and nodemask wrappers.\n\nThis patch provides that.

Replace single semaphore with two semaphores.\n\nThe suggestion to use two locks was made by Roman Zippel.\n\nBoth locks are global. Code that wants to modify cpusets must first\nacquire the exclusive manage_sem, which allows them read-only access to\ncpusets, and holds off other would-be modifiers. Before making actual\nchanges, the second semaphore, callback_sem must be acquired as well. Code\nthat needs only to query cpusets must acquire callback_sem, which is also a\nglobal exclusive lock.\n\nThe earlier problems with double tripping are avoided, because it is\nallowed for holders of manage_sem to nest the second callback_sem lock, and\nonly callback_sem is needed by code called from within __alloc_pages(),\nwhere the double tripping had been possible.\n\nThis is not quite the same as a normal read/write semaphore, because\nobtaining read-only access with intent to change must hold off other such\nattempts, while allowing read-only access w/o such intention. Changing\ncpusets involves several related checks and changes, which must be done\nwhile allowing read-only queries (to avoid the double trip), but while\nensuring nothing changes (holding off other would be modifiers.)\n\nThis overhaul of cpuset locking also makes careful use of task_lock() to\nguard access to the task-\u003ecpuset pointer, closing a couple of race\nconditions noticed while reading this code (thanks, Roman).
