As a consequence, the cpuidle states that the SoC is safe to\nenter can change from idle period to idle period. In addition, the\nlatency and threshold of each cpuidle state can vary, depending on the\noperating condition when the CPU becomes idle, e.g. the current cpu\nfrequency, the current state of the HW blocks, etc.\n\ncpuidle core and the menu governor, in the current form, are geared\ntowards cpuidle states that are static, i.e. the availabiltiy of the\nstates, their latencies, their thresholds are non-changing during run\ntime. cpuidle does not provide any hook that cpuidle drivers can use to\nadjust those values on the fly for the current idle period before the menu\ngovernor selects the target cpuidle state.\n\nThis patch extends cpuidle core and the menu governor to handle states\nthat are dynamic. There are three additions in the patch and the patch\nmaintains backwards-compatibility with existing cpuidle drivers.\n\n1) add prepare() to struct cpuidle_device. A cpuidle driver can hook\n into the callback and cpuidle will call prepare() before calling the\n governor\u0027s select function. The callback gives the cpuidle driver a\n chance to update the dynamic information of the cpuidle states for the\n current idle period, e.g. state availability, latencies, thresholds,\n power values, etc.\n\n2) add CPUIDLE_FLAG_IGNORE as one of the state flags. In the prepare()\n function, a cpuidle driver can set/clear the flag to indicate to the\n menu governor whether a cpuidle state should be ignored, i.e. not\n available, during the current idle period.\n\n3) add power_specified bit to struct cpuidle_device. The menu governor\n currently assumes that the cpuidle states are arranged in the order of\n increasing latency, threshold, and power savings. This is true or can\n be made true for static states. Once the state parameters are dynamic,\n the latencies, thresholds, and power savings for the cpuidle states can\n increase or decrease by different amounts from idle period to idle\n period. So the assumption of increasing latency, threshold, and power\n savings from Cn to C(n+1) can no longer be guaranteed.\n\nIt can be straightforward to calculate the power consumption of each\navailable state and to specify it in power_usage for the idle period.\nUsing the power_usage fields, the menu governor then selects the state\nthat has the lowest power consumption and that still satisfies all other\ncritieria. The power_specified bit defaults to 0. For existing cpuidle\ndrivers, cpuidle detects that power_specified is 0 and fills in a dummy\nset of power_usage values.\n\nSigned-off-by: Ai Li \u003caili@codeaurora.org\u003e\nCc: Len Brown \u003clen.brown@intel.com\u003e\nAcked-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Venkatesh Pallipadi \u003cvenki@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d2997b1042ec150616c1963b5e5e919ffd0b0ebf", "tree": "c970746ad3d5c3e0ccbd1695d07144dbe4534ec4", "parents": [ "966cca029f739716fbcc8068b8c6dfe381f86fc3" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Mon Aug 09 17:20:11 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Aug 09 20:45:04 2010 -0700" }, "message": "hibernation: freeze swap at hibernation\n\nWhen taking a memory snapshot in hibernate_snapshot(), all (directly\ncalled) memory allocations use GFP_ATOMIC.

The goal is to\nmake it as simple and predictable as possible so the results are better\nunderstood and we end up killing the task which will lead to the most\nmemory freeing while still respecting the fine-tuning from userspace.\n\nInstead of basing the heuristic on mm-\u003etotal_vm for each task, the task\u0027s\nrss and swap space is used instead. This is a better indication of the\namount of memory that will be freeable if the oom killed task is chosen\nand subsequently exits. This helps specifically in cases where KDE or\nGNOME is chosen for oom kill on desktop systems instead of a memory\nhogging task.\n\nThe baseline for the heuristic is a proportion of memory that each task is\ncurrently using in memory plus swap compared to the amount of \"allowable\"\nmemory. \"Allowable,\" in this sense, means the system-wide resources for\nunconstrained oom conditions, the set of mempolicy nodes, the mems\nattached to current\u0027s cpuset, or a memory controller\u0027s limit. The\nproportion is given on a scale of 0 (never kill) to 1000 (always kill),\nroughly meaning that if a task has a badness() score of 500 that the task\nconsumes approximately 50% of allowable memory resident in RAM or in swap\nspace.\n\nThe proportion is always relative to the amount of \"allowable\" memory and\nnot the total amount of RAM systemwide so that mempolicies and cpusets may\noperate in isolation; they shall not need to know the true size of the\nmachine on which they are running if they are bound to a specific set of\nnodes or mems, respectively.\n\nRoot tasks are given 3% extra memory just like __vm_enough_memory()\nprovides in LSMs. In the event of two tasks consuming similar amounts of\nmemory, it is generally better to save root\u0027s task.\n\nBecause of the change in the badness() heuristic\u0027s baseline, it is also\nnecessary to introduce a new user interface to tune it. It\u0027s not possible\nto redefine the meaning of /proc/pid/oom_adj with a new scale since the\nABI cannot be changed for backward compatability. Instead, a new tunable,\n/proc/pid/oom_score_adj, is added that ranges from -1000 to +1000. It may\nbe used to polarize the heuristic such that certain tasks are never\nconsidered for oom kill while others may always be considered. The value\nis added directly into the badness() score so a value of -500, for\nexample, means to discount 50% of its memory consumption in comparison to\nother tasks either on the system, bound to the mempolicy, in the cpuset,\nor sharing the same memory controller.\n\n/proc/pid/oom_adj is changed so that its meaning is rescaled into the\nunits used by /proc/pid/oom_score_adj, and vice versa. Changing one of\nthese per-task tunables will rescale the value of the other to an\nequivalent meaning. Although /proc/pid/oom_adj was originally defined as\na bitshift on the badness score, it now shares the same linear growth as\n/proc/pid/oom_score_adj but with different granularity. This is required\nso the ABI is not broken with userspace applications and allows oom_adj to\nbe deprecated for future removal.\n\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "74bcbf40546bb7500f2a7ba4ff3cc056a6bd004a", "tree": "39411d83f448da818368043af9b52e9b405a2002", "parents": [ "cef1d3523d33ebc35fc29e454b1f4bab953fabbf" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Mon Aug 09 17:19:43 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Aug 09 20:45:02 2010 -0700" }, "message": "oom: move badness() declaration into oom.h\n\nCc: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "25edde0332916ae706ccf83de688be57bcc844b7", "tree": "35a5b0e651f9cdb48d9a55a748970339c4f681bc", "parents": [ "b898cc70019ce1835bbf6c47bdf978adc36faa42" ], "author": { "name": "KOSAKI Motohiro", "email": "kosaki.motohiro@jp.fujitsu.com", "time": "Mon Aug 09 17:19:27 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Aug 09 20:45:00 2010 -0700" }, "message": "vmscan: kill prev_priority completely\n\nSince 2.6.28 zone-\u003eprev_priority is unused. Then it can be removed\nsafely.

Thus I give up such approach.\n\nThe rest of this changelog is notes on prev_priority and why it existed in\nthe first place and why it might be not necessary any more. This information\nis based heavily on discussions between Andrew Morton, Rik van Riel and\nKosaki Motohiro who is heavily quotes from.\n\nHistorically prev_priority was important because it determined when the VM\nwould start unmapping PTE pages. i.e. there are no balances of note within\nthe VM, Anon vs File and Mapped vs Unmapped. Without prev_priority, there\nis a potential risk of unnecessarily increasing minor faults as a large\namount of read activity of use-once pages could push mapped pages to the\nend of the LRU and get unmapped.\n\nThere is no proof this is still a problem but currently it is not considered\nto be. Active files are not deactivated if the active file list is smaller\nthan the inactive list reducing the liklihood that file-mapped pages are\nbeing pushed off the LRU and referenced executable pages are kept on the\nactive list to avoid them getting pushed out by read activity.\n\nEven if it is a problem, prev_priority prev_priority wouldn\u0027t works\nnowadays. First of all, current vmscan still a lot of UP centric code. it\nexpose some weakness on some dozens CPUs machine. I think we need more and\nmore improvement.\n\nThe problem is, current vmscan mix up per-system-pressure, per-zone-pressure\nand per-task-pressure a bit. example, prev_priority try to boost priority to\nother concurrent priority. but if the another task have mempolicy restriction,\nit is unnecessary, but also makes wrong big latency and exceeding reclaim.\nper-task based priority + prev_priority adjustment make the emulation of\nper-system pressure. but it have two issue 1) too rough and brutal emulation\n2) we need per-zone pressure, not per-system.\n\nAnother example, currently DEF_PRIORITY is 12. it mean the lru rotate about\n2 cycle (1/4096 + 1/2048 + 1/1024 + .. + 1) before invoking OOM-Killer.\nbut if 10,0000 thrreads enter DEF_PRIORITY reclaim at the same time, the\nsystem have higher memory pressure than priority\u003d\u003d0 (1/4096*10,000 \u003e 2).\nprev_priority can\u0027t solve such multithreads workload issue. In other word,\nprev_priority concept assume the sysmtem don\u0027t have lots threads.\"\n\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nReviewed-by: Johannes Weiner \u003channes@cmpxchg.org\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Chris Mason \u003cchris.mason@oracle.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Michael Rubin \u003cmrubin@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "755f0225e8347b23a33ee6e3fb14a35310f95766", "tree": "23489e9f52f1435c7b8bc4da8e98d607460e4e23", "parents": [ "a8a94d151521b248727c1f88756174e15260815a" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Mon Aug 09 17:19:18 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Aug 09 20:45:00 2010 -0700" }, "message": "vmscan: tracing: add trace event when a page is written\n\nAdd a trace event for when page reclaim queues a page for IO and records\nwhether it is synchronous or asynchronous.

The kernel is then able to cache the DNS replies as keys\ncan be retained in keyrings.\n\nResolver keys are of type \"dns_resolver\" and have a case-insensitive\ndescription that is of the form \"[\u003ctype\u003e:]\u003cdomain_name\u003e\". The optional \u003ctype\u003e\nindicates the particular DNS lookup and packaging that\u0027s required. The\n\u003cdomain_name\u003e is the query to be made.\n\nIf \u003ctype\u003e isn\u0027t given, a basic hostname to IP address lookup is made, and the\nresult is stored in the key in the form of a printable string consisting of a\ncomma-separated list of IPv4 and IPv6 addresses.\n\nThis key type is supported by userspace helpers driven from /sbin/request-key\nand configured through /etc/request-key.conf. The cifs.upcall utility is\ninvoked for UNC path server name to IP address resolution.\n\nThe CIFS functionality is encapsulated by the dns_resolve_unc_to_ip() function,\nwhich is used to resolve a UNC path to an IP address for CIFS filesystem.
