In the interest of getting the ball rolling, it would be\n desirable to see this much merged for 3.8 with the view to building\n scheduler smarts on top and adapting the VM where required for 3.9.\n\n The most recent set of comparisons available from different people are\n\n mel: https://lkml.org/lkml/2012/12/9/108\n mingo: https://lkml.org/lkml/2012/12/7/331\n tglx: https://lkml.org/lkml/2012/12/10/437\n srikar: https://lkml.org/lkml/2012/12/10/397\n\n The results are a mixed bag. In my own tests, balancenuma does\n reasonably well. It\u0027s dumb as rocks and does not regress against\n mainline. On the other hand, Ingo\u0027s tests shows that balancenuma is\n incapable of converging for this workloads driven by perf which is bad\n but is potentially explained by the lack of scheduler smarts. Thomas\u0027\n results show balancenuma improves on mainline but falls far short of\n numacore or autonuma. Srikar\u0027s results indicate we all suffer on a\n large machine with imbalanced node sizes.\n\n My own testing showed that recent numacore results have improved\n dramatically, particularly in the last week but not universally.\n We\u0027ve butted heads heavily on system CPU usage and high levels of\n migration even when it shows that overall performance is better.\n There are also cases where it regresses. Of interest is that for\n specjbb in some configurations it will regress for lower numbers of\n warehouses and show gains for higher numbers which is not reported by\n the tool by default and sometimes missed in treports. Recently I\n reported for numacore that the JVM was crashing with\n NullPointerExceptions but currently it\u0027s unclear what the source of\n this problem is. Initially I thought it was in how numacore batch\n handles PTEs but I\u0027m no longer think this is the case. It\u0027s possible\n numacore is just able to trigger it due to higher rates of migration.\n\n These reports were quite late in the cycle so I/we would like to start\n with this tree as it contains much of the code we can agree on and has\n not changed significantly over the last 2-3 weeks.\"\n\n* tag \u0027balancenuma-v11\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma: (50 commits)\n mm/rmap, migration: Make rmap_walk_anon() and try_to_unmap_anon() more scalable\n mm/rmap: Convert the struct anon_vma::mutex to an rwsem\n mm: migrate: Account a transhuge page properly when rate limiting\n mm: numa: Account for failed allocations and isolations as migration failures\n mm: numa: Add THP migration for the NUMA working set scanning fault case build fix\n mm: numa: Add THP migration for the NUMA working set scanning fault case.\n mm: sched: numa: Delay PTE scanning until a task is scheduled on a new node\n mm: sched: numa: Control enabling and disabling of NUMA balancing if !SCHED_DEBUG\n mm: sched: numa: Control enabling and disabling of NUMA balancing\n mm: sched: Adapt the scanning rate if a NUMA hinting fault does not migrate\n mm: numa: Use a two-stage filter to restrict pages being migrated for unlikely task\u003c-\u003enode relationships\n mm: numa: migrate: Set last_nid on newly allocated page\n mm: numa: split_huge_page: Transfer last_nid on tail page\n mm: numa: Introduce last_nid to the page frame\n sched: numa: Slowly increase the scanning period as NUMA faults are handled\n mm: numa: Rate limit setting of pte_numa if node is saturated\n mm: numa: Rate limit the amount of memory that is migrated between nodes\n mm: numa: Structures for Migrate On Fault per NUMA migration rate limiting\n mm: numa: Migrate pages handled during a pmd_numa hinting fault\n mm: numa: Migrate on reference policy\n ...\n" }, { "commit": "b8593bfda1652755136333cdd362de125b283a9c", "tree": "c0395d9cf775fd9225e81b055fc8f5540a14333a", "parents": [ "e42c8ff2999de1239a57d434bfbd8e9f2a56e814" ], "author": { "name": "Mel Gorman", "email": "mgorman@suse.de", "time": "Wed Nov 21 01:18:23 2012 +0000" }, "committer": { "name": "Mel Gorman", "email": "mgorman@suse.de", "time": "Tue Dec 11 14:42:55 2012 +0000" }, "message": "mm: sched: Adapt the scanning rate if a NUMA hinting fault does not migrate\n\nThe PTE scanning rate and fault rates are two of the biggest sources of\nsystem CPU overhead with automatic NUMA placement.

If the offset reaches the last mapped\naddress of the mm then it then it starts over at the first\naddress.\n\nThe per-task nature of the working set sampling functionality in this tree\nallows such constant rate, per task, execution-weight proportional sampling\nof the working set, with an adaptive sampling interval/frequency that\ngoes from once per 100ms up to just once per 8 seconds. The current\nsampling volume is 256 MB per interval.\n\nAs tasks mature and converge their working set, so does the\nsampling rate slow down to just a trickle, 256 MB per 8\nseconds of CPU time executed.\n\nThis, beyond being adaptive, also rate-limits rarely\nexecuting systems and does not over-sample on overloaded\nsystems.\n\n[ In AutoNUMA speak, this patch deals with the effective sampling\n rate of the \u0027hinting page fault\u0027. AutoNUMA\u0027s scanning is\n currently rate-limited, but it is also fundamentally\n single-threaded, executing in the knuma_scand kernel thread,\n so the limit in AutoNUMA is global and does not scale up with\n the number of CPUs, nor does it scan tasks in an execution\n proportional manner.\n\n So the idea of rate-limiting the scanning was first implemented\n in the AutoNUMA tree via a global rate limit. This patch goes\n beyond that by implementing an execution rate proportional\n working set sampling rate that is not implemented via a single\n global scanning daemon. ]\n\n[ Dan Carpenter pointed out a possible NULL pointer dereference in the\n first version of this patch. ]\n\nBased-on-idea-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nBug-Found-By: Dan Carpenter \u003cdan.carpenter@oracle.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\n[ Wrote changelog and fixed bug. ]\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\n" }, { "commit": "cbee9f88ec1b8dd6b58f25f54e4f52c82ed77690", "tree": "d4cfbcfa3e89742216cd792d4aa914356406b532", "parents": [ "a720094ded8cbb303111035be91858011d2eac71" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Thu Oct 25 14:16:43 2012 +0200" }, "committer": { "name": "Mel Gorman", "email": "mgorman@suse.de", "time": "Tue Dec 11 14:42:45 2012 +0000" }, "message": "mm: numa: Add fault driven placement and migration\n\nNOTE: This patch is based on \"sched, numa, mm: Add fault driven\n\tplacement and migration policy\" but as it throws away all the policy\n\tto just leave a basic foundation I had to drop the signed-offs-by.\n\nThis patch creates a bare-bones method for setting PTEs pte_numa in the\ncontext of the scheduler that when faulted later will be faulted onto the\nnode the CPU is running on.

The common method of exploitation\nof this flaw is to cross privilege boundaries when following a given\nhardlink (i.e. a root process follows a hardlink created by another\nuser). Additionally, an issue exists where users can \"pin\" a potentially\nvulnerable setuid/setgid file so that an administrator will not actually\nupgrade a system fully.\n\nThe solution is to permit hardlinks to only be created when the user is\nalready the existing file\u0027s owner, or if they already have read/write\naccess to the existing file.\n\nMany Linux users are surprised when they learn they can link to files\nthey have no access to, so this change appears to follow the doctrine\nof \"least surprise\". Additionally, this change does not violate POSIX,\nwhich states \"the implementation may require that the calling process\nhas permission to access the existing file\"[1].\n\nThis change is known to break some implementations of the \"at\" daemon,\nthough the version used by Fedora and Ubuntu has been fixed[2] for\na while.

It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here. Other process execution related bits\n could perhaps go here from asm/processor.h.\n\n (4) asm/cmpxchg.h\n\n Move xchg() and cmpxchg() here as they\u0027re full word atomic ops and\n frequently used by atomic_xchg() and atomic_cmpxchg().\n\n (5) asm/bug.h\n\n Move die() and related bits.\n\n (6) asm/auxvec.h\n\n Move AT_VECTOR_SIZE_ARCH here.\n\n Other arch headers are created as needed on a per-arch basis.\"\n\nFixed up some conflicts from other header file cleanups and moving code\naround that has happened in the meantime, so David\u0027s testing is somewhat\nweakened by that.

This patch\nimplements an idea from Linus, to automatically create task\ngroups. Currently, only per session autogroups are implemented,\nbut the patch leaves the way open for enhancement.\n\nImplementation: each task\u0027s signal struct contains an inherited\npointer to a refcounted autogroup struct containing a task group\npointer, the default for all tasks pointing to the\ninit_task_group. When a task calls setsid(), a new task group\nis created, the process is moved into the new task group, and a\nreference to the preveious task group is dropped. Child\nprocesses inherit this task group thereafter, and increase it\u0027s\nrefcount. When the last thread of a process exits, the\nprocess\u0027s reference is dropped, such that when the last process\nreferencing an autogroup exits, the autogroup is destroyed.\n\nAt runqueue selection time, IFF a task has no cgroup assignment,\nits current autogroup is used.\n\nAutogroup bandwidth is controllable via setting it\u0027s nice level\nthrough the proc filesystem:\n\n cat /proc/\u003cpid\u003e/autogroup\n\nDisplays the task\u0027s group and the group\u0027s nice level.\n\n echo \u003cnice level\u003e \u003e /proc/\u003cpid\u003e/autogroup\n\nSets the task group\u0027s shares to the weight of nice \u003clevel\u003e task.\nSetting nice level is rate limited for !admin users due to the\nabuse risk of task group locking.\n\nThe feature is enabled from boot by default if\nCONFIG_SCHED_AUTOGROUP\u003dy is selected, but can be disabled via\nthe boot option noautogroup, and can also be turned on/off on\nthe fly via:\n\n echo [01] \u003e
