The following patchset and glibc patch implements it,\nontop of the robust-futexes patchset which is included in 2.6.16-mm1.\n\nWe are calling it lightweight for 3 reasons:\n\n - in the user-space fastpath a PI-enabled futex involves no kernel work\n (or any other PI complexity) at all. No registration, no extra kernel\n calls - just pure fast atomic ops in userspace.\n\n - in the slowpath (in the lock-contention case), the system call and\n scheduling pattern is in fact better than that of normal futexes, due to\n the \u0027integrated\u0027 nature of FUTEX_LOCK_PI. [more about that further down]\n\n - the in-kernel PI implementation is streamlined around the mutex\n abstraction, with strict rules that keep the implementation relatively\n simple: only a single owner may own a lock (i.e. no read-write lock\n support), only the owner may unlock a lock, no recursive locking, etc.\n\n Priority Inheritance - why, oh why???\n -------------------------------------\n\nMany of you heard the horror stories about the evil PI code circling Linux for\nyears, which makes no real sense at all and is only used by buggy applications\nand which has horrible overhead. Some of you have dreaded this very moment,\nwhen someone actually submits working PI code ;-)\n\nSo why would we like to see PI support for futexes?\n\nWe\u0027d like to see it done purely for technological reasons. We dont think it\u0027s\na buggy concept, we think it\u0027s useful functionality to offer to applications,\nwhich functionality cannot be achieved in other ways. We also think it\u0027s the\nright thing to do, and we think we\u0027ve got the right arguments and the right\nnumbers to prove that. We also believe that we can address all the\ncounter-arguments as well. For these reasons (and the reasons outlined below)\nwe are submitting this patch-set for upstream kernel inclusion.\n\nWhat are the benefits of PI?\n\n The short reply:\n ----------------\n\nUser-space PI helps achieving/improving determinism for user-space\napplications. In the best-case, it can help achieve determinism and\nwell-bound latencies. Even in the worst-case, PI will improve the statistical\ndistribution of locking related application delays.\n\n The longer reply:\n -----------------\n\nFirstly, sharing locks between multiple tasks is a common programming\ntechnique that often cannot be replaced with lockless algorithms. As we can\nsee it in the kernel [which is a quite complex program in itself], lockless\nstructures are rather the exception than the norm - the current ratio of\nlockless vs. locky code for shared data structures is somewhere between 1:10\nand 1:100. Lockless is hard, and the complexity of lockless algorithms often\nendangers to ability to do robust reviews of said code. I.e. critical RT\napps often choose lock structures to protect critical data structures, instead\nof lockless algorithms. Furthermore, there are cases (like shared hardware,\nor other resource limits) where lockless access is mathematically impossible.\n\nMedia players (such as Jack) are an example of reasonable application design\nwith multiple tasks (with multiple priority levels) sharing short-held locks:\nfor example, a highprio audio playback thread is combined with medium-prio\nconstruct-audio-data threads and low-prio display-colory-stuff threads. Add\nvideo and decoding to the mix and we\u0027ve got even more priority levels.\n\nSo once we accept that synchronization objects (locks) are an unavoidable fact\nof life, and once we accept that multi-task userspace apps have a very fair\nexpectation of being able to use locks, we\u0027ve got to think about how to offer\nthe option of a deterministic locking implementation to user-space.\n\nMost of the technical counter-arguments against doing priority inheritance\nonly apply to kernel-space locks. But user-space locks are different, there\nwe cannot disable interrupts or make the task non-preemptible in a critical\nsection, so the \u0027use spinlocks\u0027 argument does not apply (user-space spinlocks\nhave the same priority inversion problems as other user-space locking\nconstructs). Fact is, pretty much the only technique that currently enables\ngood determinism for userspace locks (such as futex-based pthread mutexes) is\npriority inheritance:\n\nCurrently (without PI), if a high-prio and a low-prio task shares a lock [this\nis a quite common scenario for most non-trivial RT applications], even if all\ncritical sections are coded carefully to be deterministic (i.e. all critical\nsections are short in duration and only execute a limited number of\ninstructions), the kernel cannot guarantee any deterministic execution of the\nhigh-prio task: any medium-priority task could preempt the low-prio task while\nit holds the shared lock and executes the critical section, and could delay it\nindefinitely.\n\n Implementation:\n ---------------\n\nAs mentioned before, the userspace fastpath of PI-enabled pthread mutexes\ninvolves no kernel work at all - they behave quite similarly to normal\nfutex-based locks: a 0 value means unlocked, and a value\u003d\u003dTID means locked.\n(This is the same method as used by list-based robust futexes.) Userspace uses\natomic ops to lock/unlock these mutexes without entering the kernel.\n\nTo handle the slowpath, we have added two new futex ops:\n\n FUTEX_LOCK_PI\n FUTEX_UNLOCK_PI\n\nIf the lock-acquire fastpath fails, [i.e. an atomic transition from 0 to TID\nfails], then FUTEX_LOCK_PI is called. The kernel does all the remaining work:\nif there is no futex-queue attached to the futex address yet then the code\nlooks up the task that owns the futex [it has put its own TID into the futex\nvalue], and attaches a \u0027PI state\u0027 structure to the futex-queue. The pi_state\nincludes an rt-mutex, which is a PI-aware, kernel-based synchronization\nobject. The \u0027other\u0027 task is made the owner of the rt-mutex, and the\nFUTEX_WAITERS bit is atomically set in the futex value. Then this task tries\nto lock the rt-mutex, on which it blocks. Once it returns, it has the mutex\nacquired, and it sets the futex value to its own TID and returns. Userspace\nhas no other work to perform - it now owns the lock, and futex value contains\nFUTEX_WAITERS|TID.\n\nIf the unlock side fastpath succeeds, [i.e. userspace manages to do a TID -\u003e\n0 atomic transition of the futex value], then no kernel work is triggered.\n\nIf the unlock fastpath fails (because the FUTEX_WAITERS bit is set), then\nFUTEX_UNLOCK_PI is called, and the kernel unlocks the futex on the behalf of\nuserspace - and it also unlocks the attached pi_state-\u003ert_mutex and thus wakes\nup any potential waiters.\n\nNote that under this approach, contrary to other PI-futex approaches, there is\nno prior \u0027registration\u0027 of a PI-futex. [which is not quite possible anyway,\ndue to existing ABI properties of pthread mutexes.]\n\nAlso, under this scheme, \u0027robustness\u0027 and \u0027PI\u0027 are two orthogonal properties\nof futexes, and all four combinations are possible: futex, robust-futex,\nPI-futex, robust+PI-futex.\n\n glibc support:\n --------------\n\nUlrich Drepper and Jakub Jelinek have written glibc support for PI-futexes\n(and robust futexes), enabling robust and PI (PTHREAD_PRIO_INHERIT) POSIX\nmutexes.

Now\nsuppose that there is a system with 2 CPUs and 2 nice\u003d\u003d19 hard spinners and\n2 nice\u003d\u003d0 hard spinners running. The user of this system would be entitled\nto expect that the nice\u003d\u003d0 tasks each get 95% of a CPU and the nice\u003d\u003d19\ntasks only get 5% each. However, whether this expectation is met is pretty\nmuch down to luck as there are four equally likely distributions of the\ntasks to the CPUs that the load balancing code will consider to be balanced\nwith loads of 2.0 for each CPU. Two of these distributions involve one\nnice\u003d\u003d0 and one nice\u003d\u003d19 task per CPU and in these circumstances the users\nexpectations will be met. The other two distributions both involve both\nnice\u003d\u003d0 tasks being on one CPU and both nice\u003d\u003d19 being on the other CPU and\neach task will get 50% of a CPU and the user\u0027s expectations will not be\nmet.\n\nSolution:\n\nThe solution to this problem that is implemented in the attached patch is\nto use weighted loads when determining if the system is balanced and, when\nan imbalance is detected, to move an amount of weighted load between run\nqueues (as opposed to a number of tasks) to restore the balance. Once\nagain, the easiest way to explain why both of these measures are necessary\nis to use a simple example. Suppose that (in a slight variation of the\nabove example) that we have a two CPU system with 4 nice\u003d\u003d0 and 4 nice\u003d19\nhard spinning tasks running and that the 4 nice\u003d\u003d0 tasks are on one CPU and\nthe 4 nice\u003d\u003d19 tasks are on the other CPU. The weighted loads for the two\nCPUs would be 4.0 and 0.2 respectively and the load balancing code would\nmove 2 tasks resulting in one CPU with a load of 2.0 and the other with\nload of 2.2. If this was considered to be a big enough imbalance to\njustify moving a task and that task was moved using the current\nmove_tasks() then it would move the highest priority task that it found and\nthis would result in one CPU with a load of 3.0 and the other with a load\nof 1.2 which would result in the movement of a task in the opposite\ndirection and so on -- infinite loop. If, on the other hand, an amount of\nload to be moved is calculated from the imbalance (in this case 0.1) and\nmove_tasks() skips tasks until it find ones whose contributions to the\nweighted load are less than this amount it would move two of the nice\u003d\u003d19\ntasks resulting in a system with 2 nice\u003d\u003d0 and 2 nice\u003d19 on each CPU with\nloads of 2.1 for each CPU.\n\nOne of the advantages of this mechanism is that on a system where all tasks\nhave nice\u003d\u003d0 the load balancing calculations would be mathematically\nidentical to the current load balancing code.\n\nNotes:\n\nstruct task_struct:\n\nhas a new field load_weight which (in a trade off of space for speed)\nstores the contribution that this task makes to a CPU\u0027s weighted load when\nit is runnable.\n\nstruct runqueue:\n\nhas a new field raw_weighted_load which is the sum of the load_weight\nvalues for the currently runnable tasks on this run queue. This field\nalways needs to be updated when nr_running is updated so two new inline\nfunctions inc_nr_running() and dec_nr_running() have been created to make\nsure that this happens. This also offers a convenient way to optimize away\nthis part of the smpnice mechanism when CONFIG_SMP is not defined.\n\nint try_to_wake_up():\n\nin this function the value SCHED_LOAD_BALANCE is used to represent the load\ncontribution of a single task in various calculations in the code that\ndecides which CPU to put the waking task on. While this would be a valid\non a system where the nice values for the runnable tasks were distributed\nevenly around zero it will lead to anomalous load balancing if the\ndistribution is skewed in either direction. To overcome this problem\nSCHED_LOAD_SCALE has been replaced by the load_weight for the relevant task\nor by the average load_weight per task for the queue in question (as\nappropriate).\n\nint move_tasks():\n\nThe modifications to this function were complicated by the fact that\nactive_load_balance() uses it to move exactly one task without checking\nwhether an imbalance actually exists. This precluded the simple\noverloading of max_nr_move with max_load_move and necessitated the addition\nof the latter as an extra argument to the function. The internal\nimplementation is then modified to move up to max_nr_move tasks and\nmax_load_move of weighted load. This slightly complicates the code where\nmove_tasks() is called and if ever active_load_balance() is changed to not\nuse move_tasks() the implementation of move_tasks() should be simplified\naccordingly.\n\nstruct sched_group *find_busiest_group():\n\nSimilar to try_to_wake_up(), there are places in this function where\nSCHED_LOAD_SCALE is used to represent the load contribution of a single\ntask and the same issues are created. A similar solution is adopted except\nthat it is now the average per task contribution to a group\u0027s load (as\nopposed to a run queue) that is required. As this value is not directly\navailable from the group it is calculated on the fly as the queues in the\ngroups are visited when determining the busiest group.\n\nA key change to this function is that it is no longer to scale down\n*imbalance on exit as move_tasks() uses the load in its scaled form.\n\nvoid set_user_nice():\n\nhas been modified to update the task\u0027s load_weight field when it\u0027s nice\nvalue and also to ensure that its run queue\u0027s raw_weighted_load field is\nupdated if it was runnable.\n\nFrom: \"Siddha, Suresh B\" \u003csuresh.b.siddha@intel.com\u003e\n\nWith smpnice, sched groups with highest priority tasks can mask the imbalance\nbetween the other sched groups with in the same domain. This patch fixes some\nof the listed down scenarios by not considering the sched groups which are\nlightly loaded.\n\na) on a simple 4-way MP system, if we have one high priority and 4 normal\n priority tasks, with smpnice we would like to see the high priority task\n scheduled on one cpu, two other cpus getting one normal task each and the\n fourth cpu getting the remaining two normal tasks. but with current\n smpnice extra normal priority task keeps jumping from one cpu to another\n cpu having the normal priority task. This is because of the\n busiest_has_loaded_cpus, nr_loaded_cpus logic.. We are not including the\n cpu with high priority task in max_load calculations but including that in\n total and avg_load calcuations.. leading to max_load \u003c avg_load and load\n balance between cpus running normal priority tasks(2 Vs 1) will always show\n imbalanace as one normal priority and the extra normal priority task will\n keep moving from one cpu to another cpu having normal priority task..\n\nb) 4-way system with HT (8 logical processors). Package-P0 T0 has a\n highest priority task, T1 is idle. Package-P1 Both T0 and T1 have 1 normal\n priority task each.. P2 and P3 are idle. With this patch, one of the\n normal priority tasks on P1 will be moved to P2 or P3..\n\nc) With the current weighted smp nice calculations, it doesn\u0027t always make\n sense to look at the highest weighted runqueue in the busy group..\n Consider a load balance scenario on a DP with HT system, with Package-0\n containing one high priority and one low priority, Package-1 containing one\n low priority(with other thread being idle).. Package-1 thinks that it need\n to take the low priority thread from Package-0. And find_busiest_queue()\n returns the cpu thread with highest priority task.. And ultimately(with\n help of active load balance) we move high priority task to Package-1. And\n same continues with Package-0 now, moving high priority task from package-1\n to package-0.. Even without the presence of active load balance, load\n balance will fail to balance the above scenario..

Im not\nincluding those patches here; they (the patch + doc-pre-patch) are still quite\nraw (and unreviewed on KNML), and since they \u0027invent\u0027 a convention for GPIO, a\nproper vetting is needed.

I\u0027m now\nconsidering node-hot-add with cpu + memory on ACPI.\n\nI found acpi container, which describes node, could evaluate cpu before\nmemory. This means cpu-hot-add occurs before memory hot add.\n\nIn most part, cpu-hot-add doesn\u0027t depend on node hot add. But register_cpu(),\nwhich creates symbolic link from node to cpu, requires that node should be\nonlined before register_cpu(). When a node is onlined, its pgdat should be\nthere.\n\nThis patch-set holds off creating symbolic link from node to cpu\nuntil node is onlined.\n\nThis removes node arguments from register_cpu().\n\nNow, register_cpu() requires \u0027struct node\u0027 as its argument. But the array of\nstruct node is now unified in driver/base/node.c now (By Goto\u0027s node hotplug\npatch). We can get struct node in generic way. So, this argument is not\nnecessary now.\n\nThis patch also guarantees add cpu under node only when node is onlined. It\nis necessary for node-hot-add vs. cpu-hot-add patch following this.\n\nMoreover, register_cpu calculates cpu-\u003enode_id by cpu_to_node() without regard\nto its \u0027struct node *root\u0027 argument.
