A process may\nhave migrated to another node. Memory was allocated optimally for the prior\ncontext. sys_migrate_pages allows to shift the memory to the new node.\n\nsys_migrate_pages is also useful if the processes available memory nodes have\nchanged through cpuset operations to manually move the processes memory. Paul\nJackson is working on an automated mechanism that will allow an automatic\nmigration if the cpuset of a process is changed. However, a user may decide\nto manually control the migration.\n\nThis implementation is put into the policy layer since it uses concepts and\nfunctions that are also needed for mbind and friends. The patch also provides\na do_migrate_pages function that may be useful for cpusets to automatically\nmove memory. sys_migrate_pages does not modify policies in contrast to Ray\u0027s\nimplementation.\n\nThe current code here is based on the swap based page migration capability and\nthus is not able to preserve the physical layout relative to it containing\nnodeset (which may be a cpuset). When direct page migration becomes available\nthen the implementation needs to be changed to do a isomorphic move of pages\nbetween different nodesets. The current implementation simply evicts all\npages in source nodeset that are not in the target nodeset.\n\nPatch supports ia64, i386 and x86_64.\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": "67207b9664a8d603138ef1556141e6d0a102bea7", "tree": "e98886778be65aeb6625a5f516873bbc5beeb978", "parents": [ "d7a301033f1990188f65abf4fe8e5b90ef0e3888" ], "author": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Tue Nov 15 15:53:48 2005 -0500" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Jan 09 14:49:12 2006 +1100" }, "message": "[PATCH] spufs: The SPU file system, base\n\nThis is the current version of the spu file system, used\nfor driving SPEs on the Cell Broadband Engine.\n\nThis release is almost identical to the version for the\n2.6.14 kernel posted earlier, which is available as part\nof the Cell BE Linux distribution from\nhttp://www.bsc.es/projects/deepcomputing/linuxoncell/.\n\nThe first patch provides all the interfaces for running\nspu application, but does not have any support for\ndebugging SPU tasks or for scheduling.

While i\u0027m sure Martin is\ntrying to solve a real problem, we must not hard-code an incomplete and\ninsufficient approach into a syscall, because syscalls are pretty much\nfor eternity. I am quite strongly convinced that this syscall must not\nhit v2.6.13 in its current form.\n\nFirstly, the syscall lacks basic syscall design: e.g. it allows the\nglobal setting of VM policy for unprivileged users. (!) [ Imagine an\nOracle installation and a SAP installation on the same NUMA box fighting\nover the \u0027optimal\u0027 setting for this flag. What will they do? Will they\ntry to set the flag to their own preferred value every second or so? ]\n\nSecondly, it was added based on a single datapoint from Martin:\n\n http://marc.theaimsgroup.com/?l\u003dlinux-mm\u0026m\u003d111763597218177\u0026w\u003d2\n\nwhere Martin characterizes the numbers the following way:\n\n \u0027 Run-to-run variability for \"make -j\" is huge, so these numbers aren\u0027t\n terribly useful except to see that with reclaim the benchmark still\n finishes in a reasonable amount of time. \u0027\n\nin other words: the fundamental problem has likely not been solved, only\na tendential move into the right direction has been observed, and a\nhandful of numbers were picked out of a set of hugely variable results,\nwithout showing the variability data. How much variance is there\nrun-to-run?\n\nI\u0027d really suggest to first walk the walk and see what\u0027s needed to get\nstable \u0026 predictable kernel compilation numbers on that NUMA box, before\nadding random syscalls to tune a particular aspect of the VM ... which\napproach might not even matter once the whole picture has been analyzed\nand understood!\n\nThe third, most important point is that the syscall exposes VM tuning\ninternals in a completely unstructured way. What sense does it make to\nhave a _GLOBAL_ per-node setting for \u0027should we go to another node for\nreclaim\u0027? If then it might make sense to do this per-app, via numalib or\nso.\n\nThe change is minimalistic in that it doesnt remove the syscall and the\nunderlying infrastructure changes, only the user-visible changes. We\ncould perhaps add a CAP_SYS_ADMIN-only sysctl for this hack, a\u0027ka\n/proc/sys/vm/swappiness, but even that looks quite counterproductive\nwhen the generic approach is that we are trying to reduce the number of\nexternal factors in the VM balance picture.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0eeca28300df110bd6ed54b31193c83b87921443", "tree": "7db42d8a18d80eca538f5b7d25e0532b8fa38b85", "parents": [ "bd4c625c061c2a38568d0add3478f59172455159" ], "author": { "name": "Robert Love", "email": "rml@novell.com", "time": "Tue Jul 12 17:06:03 2005 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jul 12 20:38:38 2005 -0700" }, "message": "[PATCH] inotify\n\ninotify is intended to correct the deficiencies of dnotify, particularly\nits inability to scale and its terrible user interface:\n\n * dnotify requires the opening of one fd per each directory\n that you intend to watch.
