The\nprocessor however has not much to do with the zone these pages belong to. We\ncannot tell f.e. how many ZONE_DMA pages are dirty.\n\nSo we are blind to potentially inbalances in the usage of memory in various\nzones. F.e. in a NUMA system we cannot tell how many pages are dirty on a\nparticular node. If we knew then we could put measures into the VM to balance\nthe use of memory between different zones and different nodes in a NUMA\nsystem. For example it would be possible to limit the dirty pages per node so\nthat fast local memory is kept available even if a process is dirtying huge\namounts of pages.\n\nAnother example is zone reclaim. We do not know how many unmapped pages exist\nper zone. So we just have to try to reclaim. If it is not working then we\npause and try again later. It would be better if we knew when it makes sense\nto reclaim unmapped pages from a zone. This patchset allows the determination\nof the number of unmapped pages per zone. We can remove the zone reclaim\ninterval with the counters introduced here.\n\nFuthermore the ability to have various usage statistics available will allow\nthe development of new NUMA balancing algorithms that may be able to improve\nthe decision making in the scheduler of when to move a process to another node\nand hopefully will also enable automatic page migration through a user space\nprogram that can analyse the memory load distribution and then rebalance\nmemory use in order to increase performance.\n\nThe counter framework here implements differential counters for each processor\nin struct zone. The differential counters are consolidated when a threshold\nis exceeded (like done in the current implementation for nr_pageache), when\nslab reaping occurs or when a consolidation function is called.\n\nConsolidation uses atomic operations and accumulates counters per zone in the\nzone structure and also globally in the vm_stat array. VM functions can\naccess the counts by simply indexing a global or zone specific array.\n\nThe arrangement of counters in an array also simplifies processing when output\nhas to be generated for /proc/*.\n\nCounters can be updated by calling inc/dec_zone_page_state or\n_inc/dec_zone_page_state analogous to *_page_state. The second group of\nfunctions can be called if it is known that interrupts are disabled.\n\nSpecial optimized increment and decrement functions are provided. These can\navoid certain checks and use increment or decrement instructions that an\narchitecture may provide.\n\nWe also add a new CONFIG_DMA_IS_NORMAL that signifies that an architecture can\ndo DMA to all memory and therefore ZONE_NORMAL will not be populated. This is\nonly currently set for IA64 SGI SN2 and currently only affects\nnode_page_state(). In the best case node_page_state can be reduced to\nretrieving a single counter for the one zone on the node.\n\n[akpm@osdl.org: cleanups]\n[akpm@osdl.org: export vm_stat[] for filesystems]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f6ac2354d791195ca40822b84d73d48a4e8b7f2b", "tree": "5f600175cf3591eac3d32bb8cebfd45d0aabf804", "parents": [ "672b2714ae57af16fe7d760dc4e0918a7a6cb0fa" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Fri Jun 30 01:55:32 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 30 11:25:34 2006 -0700" }, "message": "[PATCH] zoned vm counters: create vmstat.c/.h from page_alloc.c/.h\n\nNOTE: ZVC are *not* the lightweight event counters. ZVCs are reliable whereas\nevent counters do not need to be.\n\nZone based VM statistics are necessary to be able to determine what the state\nof memory in one zone is. In a NUMA system this can be helpful for local\nreclaim and other memory optimizations that may be able to shift VM load in\norder to get more balanced memory use.\n\nIt is also useful to know how the computing load affects the memory\nallocations on various zones. This patchset allows the retrieval of that data\nfrom userspace.\n\nThe patchset introduces a framework for counters that is a cross between the\nexisting page_stats --which are simply global counters split per cpu-- and the\napproach of deferred incremental updates implemented for nr_pagecache.\n\nSmall per cpu 8 bit counters are added to struct zone. If the counter exceeds\ncertain thresholds then the counters are accumulated in an array of\natomic_long in the zone and in a global array that sums up all zone values.\nThe small 8 bit counters are next to the per cpu page pointers and so they\nwill be in high in the cpu cache when pages are allocated and freed.\n\nAccess to VM counter information for a zone and for the whole machine is then\npossible by simply indexing an array (Thanks to Nick Piggin for pointing out\nthat approach). The access to the total number of pages of various types does\nno longer require the summing up of all per cpu counters.\n\nBenefits of this patchset right now:\n\n- Ability for UP and SMP configuration to determine how memory\n is balanced between the DMA, NORMAL and HIGHMEM zones.\n\n- loops over all processors are avoided in writeback and\n reclaim paths. We can avoid caching the writeback information\n because the needed information is directly accessible.\n\n- Special handling for nr_pagecache removed.\n\n- zone_reclaim_interval vanishes since VM stats can now determine\n when it is worth to do local reclaim.\n\n- Fast inline per node page state determination.\n\n- Accurate counters in /sys/devices/system/node/node*/meminfo. Current\n counters are counting simply which processor allocated a page somewhere\n and guestimate based on that. So the counters were not useful to show\n the actual distribution of page use on a specific zone.\n\n- The swap_prefetch patch requires per node statistics in order to\n figure out when processors of a node can prefetch.

The application\ncan then use this security context to determine the security context for\nprocessing on behalf of the peer who sent the packet.\n\nPatch design and implementation:\n\nThe design and implementation is very similar to the UDP case for INET\nsockets. Basically we build upon the existing Unix domain socket API for\nretrieving user credentials. Linux offers the API for obtaining user\ncredentials via ancillary messages (i.e., out of band/control messages\nthat are bundled together with a normal message). To retrieve the security\ncontext, the application first indicates to the kernel such desire by\nsetting the SO_PASSSEC option via getsockopt. Then the application\nretrieves the security context using the auxiliary data mechanism.\n\nAn example server application for Unix datagram socket should look like this:\n\ntoggle \u003d 1;\ntoggle_len \u003d sizeof(toggle);\n\nsetsockopt(sockfd, SOL_SOCKET, SO_PASSSEC, \u0026toggle, \u0026toggle_len);\nrecvmsg(sockfd, \u0026msg_hdr, 0);\nif (msg_hdr.msg_controllen \u003e sizeof(struct cmsghdr)) {\n cmsg_hdr \u003d CMSG_FIRSTHDR(\u0026msg_hdr);\n if (cmsg_hdr-\u003ecmsg_len \u003c\u003d CMSG_LEN(sizeof(scontext)) \u0026\u0026\n cmsg_hdr-\u003ecmsg_level \u003d\u003d SOL_SOCKET \u0026\u0026\n cmsg_hdr-\u003ecmsg_type \u003d\u003d SCM_SECURITY) {\n memcpy(\u0026scontext, CMSG_DATA(cmsg_hdr), sizeof(scontext));\n }\n}\n\nsock_setsockopt is enhanced with a new socket option SOCK_PASSSEC to allow\na server socket to receive security context of the peer.\n\nTesting:\n\nWe have tested the patch by setting up Unix datagram client and server\napplications. We verified that the server can retrieve the security context\nusing the auxiliary data mechanism of recvmsg.\n\nSigned-off-by: Catherine Zhang \u003ccxzhang@watson.ibm.com\u003e\nAcked-by: Acked-by: James Morris \u003cjmorris@namei.org\u003e\nSigned-off-by: David S.

genirq: rename desc-\u003ehandler to desc-\u003echip\n\nThis patch-queue improves the generic IRQ layer to be truly generic, by adding\nvarious abstractions and features to it, without impacting existing\nfunctionality.\n\nWhile the queue can be best described as \"fix and improve everything in the\ngeneric IRQ layer that we could think of\", and thus it consists of many\nsmaller features and lots of cleanups, the one feature that stands out most is\nthe new \u0027irq chip\u0027 abstraction.\n\nThe irq-chip abstraction is about describing and coding and IRQ controller\ndriver by mapping its raw hardware capabilities [and quirks, if needed] in a\nstraightforward way, without having to think about \"IRQ flow\"\n(level/edge/etc.) type of details.\n\nThis stands in contrast with the current \u0027irq-type\u0027 model of genirq\narchitectures, which \u0027mixes\u0027 raw hardware capabilities with \u0027flow\u0027 details.\nThe patchset supports both types of irq controller designs at once, and\nconverts i386 and x86_64 to the new irq-chip design.\n\nAs a bonus side-effect of the irq-chip approach, chained interrupt controllers\n(master/slave PIC constructs, etc.) are now supported by design as well.\n\nThe end result of this patchset intends to be simpler architecture-level code\nand more consolidation between architectures.\n\nWe reused many bits of code and many concepts from Russell King\u0027s ARM IRQ\nlayer, the merging of which was one of the motivations for this patchset.\n\nThis patch:\n\nrename desc-\u003ehandler to desc-\u003echip.\n\nOriginally i did not want to do this, because it\u0027s a big patch. But having\nboth \"desc-\u003ehandler\", \"desc-\u003ehandle_irq\" and \"action-\u003ehandler\" caused a\nlarge degree of confusion and made the code appear alot less clean than it\ntruly is.\n\nI have also attempted a dual approach as well by introducing a\ndesc-\u003echip alias - but that just wasnt robust enough and broke\nfrequently.\n\nSo lets get over with this quickly. The conversion was done automatically\nvia scripts and converts all the code in the kernel.\n\nThis renaming patch is the first one amongst the patches, so that the\nremaining patches can stay flexible and can be merged and split up\nwithout having some big monolithic patch act as a merge barrier.\n\n[akpm@osdl.org: build fix]\n[akpm@osdl.org: another build fix]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "9dc3885dfbebc76f4461b19e1af15e704ff4fcb0", "tree": "6bdc5c1f00039dbbc94bada9cac215f88fad2f60", "parents": [ "699352c30da8525a6224116983dab012689a0a76" ], "author": { "name": "Karsten Keil", "email": "kkeil@suse.de", "time": "Thu Jun 29 02:24:33 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Jun 29 10:26:21 2006 -0700" }, "message": "[PATCH] i4l: remove unneeded include/linux/isdn/tpam.h\n\nThe TPAM isdn driver was removed in 2.6.12, but include/linux/isdn/tpam.h\nwas missed.\n\nSigned-off-by: Karsten Keil \u003ckkeil@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "4e54f08543d05e519e601368571cc3787fefae96", "tree": "0cd9d982e5bb25abcb9251d26c36ff11e7dc81a5", "parents": [ "94583779e6625154e8d7fce33d097ae7d089e9de" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Jun 29 02:24:28 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Jun 29 10:26:20 2006 -0700" }, "message": "[PATCH] Keys: Allow in-kernel key requestor to pass auxiliary data to upcaller\n\nThe proposed NFS key type uses its own method of passing key requests to\nuserspace (upcalling) rather than invoking /sbin/request-key.

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. (PTHREAD_PRIO_PROTECT support will be added later on too, no\nadditional kernel changes are needed for that). [NOTE: The glibc patch is\nobviously inofficial and unsupported without matching upstream kernel\nfunctionality.]\n\nthe patch-queue and the glibc patch can also be downloaded from:\n\n http://redhat.com/~mingo/PI-futex-patches/\n\nMany thanks go to the people who helped us create this kernel feature: Steven\nRostedt, Esben Nielsen, Benedikt Spranger, Daniel Walker, John Cooper, Arjan\nvan de Ven, Oleg Nesterov and others.

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.. Fix find_busiest_queue\n to use \"imbalance\" when it is lightly loaded.\n\n[kernel@kolivas.org: sched: store weighted load on up]\n[kernel@kolivas.org: sched: add discrete weighted cpu load function]\n[suresh.b.siddha@intel.com: sched: remove dead code]\nSigned-off-by: Peter Williams \u003cpwil3058@bigpond.com.au\u003e\nCc: \"Siddha, Suresh B\" \u003csuresh.b.siddha@intel.com\u003e\nCc: \"Chen, Kenneth W\" \u003ckenneth.w.chen@intel.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Con Kolivas \u003ckernel@kolivas.org\u003e\nCc: John Hawkes \u003chawkes@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f31000e573da052b6b8bcc21faff520b4e2eda7a", "tree": "670d5e6e00da615f70d99a950cfe7b8603edad26", "parents": [ "58b087cda1e9e46c7061c2282f92bd8e1970bfe7" ], "author": { "name": "Jim Cromie", "email": "jim.cromie@gmail.com", "time": "Tue Jun 27 02:54:23 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Jun 27 17:32:43 2006 -0700" }, "message": "[PATCH] chardev: GPIO for SCx200 \u0026 PC-8736x: use dev_dbg in common module\n\nUse of dev_dbg() and friends is considered good practice. dev_dbg() needs a\nstruct device *devp, but nsc_gpio is only a helper module, so it doesnt\nhave/need its own.

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.

Driver specific open()s set private_data to the vtable so its\navailable for use by write().\n\nThe vtable gets the gpio_dump() too, since its user-friendly, and (could be\nconstrued as) part of the current device-file interface.

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.
