To solve this:\n\n- I\u0027ve added a \u0027domain distance\u0027 function, which is used to cache\n measurement results. Each distance is only measured once. This means\n that e.g. on NUMA distances of 0, 1 and 2 might be measured, on HT\n distances 0 and 1, and on SMP distance 0 is measured. The code walks\n the domain tree to determine the distance, so it automatically follows\n whatever hierarchy an architecture sets up. This cuts down on the boot\n time significantly and removes the O(N^2) limit. The only assumption\n is that migration costs can be expressed as a function of domain\n distance - this covers the overwhelming majority of existing systems,\n and is a good guess even for more assymetric systems.\n\n [ People hacking systems that have assymetries that break this\n assumption (e.g. different CPU speeds) should experiment a bit with\n the cpu_distance() function. Adding a -\u003emigration_distance factor to\n the domain structure would be one possible solution - but lets first\n see the problem systems, if they exist at all. Lets not overdesign. ]\n\nAnother problem was that only a single cache-size was used for measuring\nthe cost of migration, and most architectures didnt set that variable\nup. Furthermore, a single cache-size does not fit NUMA hierarchies with\nL3 caches and does not fit HT setups, where different CPUs will often\nhave different \u0027effective cache sizes\u0027. To solve this problem:\n\n- Instead of relying on a single cache-size provided by the platform and\n sticking to it, the code now auto-detects the \u0027effective migration\n cost\u0027 between two measured CPUs, via iterating through a wide range of\n cachesizes. The code searches for the maximum migration cost, which\n occurs when the working set of the test-workload falls just below the\n \u0027effective cache size\u0027. I.e. real-life optimized search is done for\n the maximum migration cost, between two real CPUs.\n\n This, amongst other things, has the positive effect hat if e.g. two\n CPUs share a L2/L3 cache, a different (and accurate) migration cost\n will be found than between two CPUs on the same system that dont share\n any caches.\n\n(The reliable measurement of migration costs is tricky - see the source\nfor details.)\n\nFurthermore i\u0027ve added various boot-time options to override/tune\nmigration behavior.\n\nFirstly, there\u0027s a blanket override for autodetection:\n\n\tmigration_cost\u003d1000,2000,3000\n\nwill override the depth 0/1/2 values with 1msec/2msec/3msec values.\n\nSecondly, there\u0027s a global factor that can be used to increase (or\ndecrease) the autodetected values:\n\n\tmigration_factor\u003d120\n\nwill increase the autodetected values by 20%. This option is useful to\ntune things in a workload-dependent way - e.g. if a workload is\ncache-insensitive then CPU utilization can be maximized by specifying\nmigration_factor\u003d0.\n\nI\u0027ve tested the autodetection code quite extensively on x86, on 3\nP3/Xeon/2MB, and the autodetected values look pretty good:\n\nDual Celeron (128K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 131072, cpu: 467 MHz):\n ---------------------\n [00] [01]\n [00]: - 1.7(1)\n [01]: 1.7(1) -\n ---------------------\n cacheflush times [2]: 0.0 (0) 1.7 (1784008)\n ---------------------\n\nHere the slow memory subsystem dominates system performance, and even\nthough caches are small, the migration cost is 1.7 msecs.\n\nDual HT P4 (512K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 524288, cpu: 2379 MHz):\n ---------------------\n [00] [01] [02] [03]\n [00]: - 0.4(1) 0.0(0) 0.4(1)\n [01]: 0.4(1) - 0.4(1) 0.0(0)\n [02]: 0.0(0) 0.4(1) - 0.4(1)\n [03]: 0.4(1) 0.0(0) 0.4(1) -\n ---------------------\n cacheflush times [2]: 0.0 (33900) 0.4 (448514)\n ---------------------\n\nHere it can be seen that there is no migration cost between two HT\nsiblings (CPU#0/2 and CPU#1/3 are separate physical CPUs).

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": "ed03f430cdc8c802652467e9097606fedc2c7abc", "tree": "30941ec1e6f93e99358fefe18175e5dd800a4379", "parents": [ "ed349a8a0a780ed27e2a765f16cee54d9b63bfee", "6f957eaf79356a32e838f5f262ee9a60544b1d5b" ], "author": { "name": "Len Brown", "email": "len.brown@intel.com", "time": "Sat Jan 07 03:50:18 2006 -0500" }, "committer": { "name": "Len Brown", "email": "len.brown@intel.com", "time": "Sat Jan 07 03:50:18 2006 -0500" }, "message": "Pull pnpacpi into acpica branch\n" }, { "commit": "1fa744e6e91a895750b9980d13fcfc5791a0cd91", "tree": "2ba30e6d4f263cdb5e5ec9a85fc1fecec9100036", "parents": [ "766c3f94d4492ee4ec60b65693e71ee4b1d6fd68" ], "author": { "name": "Shaohua Li", "email": "shaohua.li@intel.com", "time": "Fri Jan 06 00:12:20 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:33:39 2006 -0800" }, "message": "[PATCH] cpu hotplug/x86_64: disable interrupt in play_dead\n\nWith physical CPU hotplug, the CPU is hot removed and it should not receive\nany interrupts.

However the only way to\nrelease tmpfs-swap is to MADV_REMOVE\". - Andrea Arcangeli\n\nDatabases want to use this feature to drop a section of their bufferpool\n(shared memory segments) - without writing back to disk/swap space.\n\nThis feature is also useful for supporting hot-plug memory on UML.\n\nConcerns raised by Andrew Morton:\n\n- \"We have no plan for holepunching! If we _do_ have such a plan (or\n might in the future) then what would the API look like? I think\n sys_holepunch(fd, start, len), so we should start out with that.\"\n\n- Using madvise is very weird, because people will ask \"why do I need to\n mmap my file before I can stick a hole in it?\"\n\n- None of the other madvise operations call into the filesystem in this\n manner. A broad question is: is this capability an MM operation or a\n filesytem operation? truncate, for example, is a filesystem operation\n which sometimes has MM side-effects. madvise is an mm operation and with\n this patch, it gains FS side-effects, only they\u0027re really, really\n significant ones.\"\n\nComments:\n\n- Andrea suggested the fs operation too but then it\u0027s more efficient to\n have it as a mm operation with fs side effects, because they don\u0027t\n immediatly know fd and physical offset of the range. It\u0027s possible to\n fixup in userland and to use the fs operation but it\u0027s more expensive,\n the vmas are already in the kernel and we can use them.\n\nShort term plan \u0026 Future Direction:\n\n- We seem to need this interface only for shmfs/tmpfs files in the short\n term. We have to add hooks into the filesystem for correctness and\n completeness. This is what this patch does.\n\n- In the future, plan is to support both fs and mmap apis also. This\n also involves (other) filesystem specific functions to be implemented.\n\n- Current patch doesn\u0027t support VM_NONLINEAR - which can be addressed in\n the future.\n\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Andrea Arcangeli \u003candrea@suse.de\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "90933fc8ba5cc9034e3c04ee19938a22b0b4fe4e", "tree": "e42a78d253b375025cf73efe0f582d2722619397", "parents": [ "3821af2fe13700cab6fd67367128fa180e43f8b8" ], "author": { "name": "Stephen Hemminger", "email": "shemminger@osdl.org", "time": "Wed Dec 21 19:31:36 2005 -0800" }, "committer": { "name": "David S.
