But the \u0027ran\u0027 field fluctuates around 13.33 msecs and there\u0027s no\nmechanism in CFS to keep that from happening: it\u0027s a perfectly valid\nsolution that CFS finds.\n\nto fix this we add a granularity/preemption rule that knows about\nthe \"target latency\", which makes tasks that run longer than the ideal\nlatency run a bit less. The simplest approach is to simply decrease the\npreemption granularity when a task overruns its ideal latency. For this\nwe have to track how much the task executed since its last preemption.\n\n( this adds a new field to task_struct, but we can eliminate that\n  overhead in 2.6.24 by putting all the scheduler timestamps into an\n  anonymous union. )\n\nwith this change in place, chew-max output is fluctuation-less all\naround:\n\n out:  28 . 27. 39 | flu:  0 .  2 | ran:   13 .   13 | per:   41 .   40\n out:  28 . 27. 39 | flu:  0 .  2 | ran:   13 .   13 | per:   41 .   40\n out:  28 . 27. 39 | flu:  0 .  2 | ran:   13 .   13 | per:   41 .   40\n out:  28 . 27. 39 | flu:  0 .  2 | ran:   13 .   13 | per:   41 .   40\n out:  28 . 27. 39 | flu:  0 .  1 | ran:   13 .   13 | per:   41 .   40\n out:  28 . 27. 39 | flu:  0 .  1 | ran:   13 .   13 | per:   41 .   40\n\nthis patch has no impact on any fastpath or on any globally observable\nscheduling property.

      "message": "sched: fix sleeper bonus limit\n\nThere is an Amarok song switch time increase (regression) under\nhefty load.\n\nWhat is happening is that sleeper_bonus is never consumed, and only\nrarely goes below runtime_limit, so for the most part, Amarok isn\u0027t\ngetting any bonus at all.  We\u0027re keeping sleeper_bonus right at\nruntime_limit (sched_latency \u003d\u003d sched_runtime_limit \u003d\u003d 40ms) forever, ie\nwe don\u0027t consume if we\u0027re lower that that, and don\u0027t add if we\u0027re above\nit.  One Amarok thread waking (or anybody else) will push us past the\nthreshold, so the next thread waking gets nada, but will reap pain from\nthe previous thread waking until we drop back to runtime_limit.  It\nlooks to me like under load, some random task gets a bonus, and\neverybody else pays, whether deserving or not.\n\nThis diff fixed the regression for me at any load rate.\n\nSigned-off-by: Mike Galbraith \u003cefault@gmx.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\n"

      "message": "sched: fix bug in balance_tasks()\n\nThere are two problems with balance_tasks() and how it used:\n\n1. The variables best_prio and best_prio_seen (inherited from the old\nmove_tasks()) were only required to handle problems caused by the\nactive/expired arrays, the order in which they were processed and the\npossibility that the task with the highest priority could be on either.\n  These issues are no longer present and the extra overhead associated\nwith their use is unnecessary (and possibly wrong).\n\n2. In the absence of CONFIG_FAIR_GROUP_SCHED being set, the same\nthis_best_prio variable needs to be used by all scheduling classes or\nthere is a risk of moving too much load.  E.g. if the highest priority\ntask on this at the beginning is a fairly low priority task and the rt\nclass migrates a task (during its turn) then that moved task becomes the\nnew highest priority task on this_rq but when the sched_fair class\ninitializes its copy of this_best_prio it will get the priority of the\noriginal highest priority task as, due to the run queue locks being\nheld, the reschedule triggered by pull_task() will not have taken place.\n  This could result in inappropriate overriding of skip_for_load and\nexcessive load being moved.\n\nThe attached patch addresses these problems by deleting all reference to\nbest_prio and best_prio_seen and making this_best_prio a reference\nparameter to the various functions involved.\n\nload_balance_fair() has also been modified so that this_best_prio is\nonly reset (in the loop) if CONFIG_FAIR_GROUP_SCHED is set.  This should\npreserve the effect of helping spread groups\u0027 higher priority tasks\naround the available CPUs while improving system performance when\nCONFIG_FAIR_GROUP_SCHED isn\u0027t set.\n\nSigned-off-by: Peter Williams \u003cpwil3058@bigpond.net.au\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "sched: simplify move_tasks()\n\nThe move_tasks() function is currently multiplexed with two distinct\ncapabilities:\n\n1. attempt to move a specified amount of weighted load from one run\nqueue to another; and\n2. attempt to move a specified number of tasks from one run queue to\nanother.\n\nThe first of these capabilities is used in two places, load_balance()\nand load_balance_idle(), and in both of these cases the return value of\nmove_tasks() is used purely to decide if tasks/load were moved and no\nnotice of the actual number of tasks moved is taken.\n\nThe second capability is used in exactly one place,\nactive_load_balance(), to attempt to move exactly one task and, as\nbefore, the return value is only used as an indicator of success or failure.\n\nThis multiplexing of sched_task() was introduced, by me, as part of the\nsmpnice patches and was motivated by the fact that the alternative, one\nfunction to move specified load and one to move a single task, would\nhave led to two functions of roughly the same complexity as the old\nmove_tasks() (or the new balance_tasks()).  However, the new modular\ndesign of the new CFS scheduler allows a simpler solution to be adopted\nand this patch addresses that solution by:\n\n1. adding a new function, move_one_task(), to be used by\nactive_load_balance(); and\n2. making move_tasks() a single purpose function that tries to move a\nspecified weighted load and returns 1 for success and 0 for failure.\n\nOne of the consequences of these changes is that neither move_one_task()\nor the new move_tasks() care how many tasks sched_class.load_balance()\nmoves and this enables its interface to be simplified by returning the\namount of load moved as its result and removing the load_moved pointer\nfrom the argument list.  This helps simplify the new move_tasks() and\nslightly reduces the amount of work done in each of\nsched_class.load_balance()\u0027s implementations.\n\nFurther simplification, e.g. changes to balance_tasks(), are possible\nbut (slightly) complicated by the special needs of load_balance_fair()\nso I\u0027ve left them to a later patch (if this one gets accepted).\n\nNB Since move_tasks() gets called with two run queue locks held even\nsmall reductions in overhead are worthwhile.\n\n[ mingo@elte.hu ]\n\nthis change also reduces code size nicely:\n\n   text    data     bss     dec     hex filename\n   39216    3618      24   42858    a76a sched.o.before\n   39173    3618      24   42815    a73f sched.o.after\n\nSigned-off-by: Peter Williams \u003cpwil3058@bigpond.net.au\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
