This may be improved by using\nhighmem for saving the contents of saveable highmem pages.\n\nNamely, during the suspend phase of the suspend-resume cycle we try to\nallocate as many free highmem pages as there are saveable highmem pages.\nIf there are not enough highmem image pages to store the contents of all of\nthe saveable highmem pages, some of them will be stored in the \"normal\"\nmemory. Next, we allocate as many free \"normal\" pages as needed to store\nthe (remaining) image data. We use a memory bitmap to mark the allocated\nfree pages (ie. highmem as well as \"normal\" image pages).\n\nNow, we use another memory bitmap to mark all of the saveable pages\n(highmem as well as \"normal\") and the contents of the saveable pages are\ncopied into the image pages. Then, the second bitmap is used to save the\npfns corresponding to the saveable pages and the first one is used to save\ntheir data.\n\nDuring the resume phase the pfns of the pages that were saveable during the\nsuspend are loaded from the image and used to mark the \"unsafe\" page\nframes. Next, we try to allocate as many free highmem page frames as to\nload all of the image data that had been in the highmem before the suspend\nand we allocate so many free \"normal\" page frames that the total number of\nallocated free pages (highmem and \"normal\") is equal to the size of the\nimage. While doing this we have to make sure that there will be some extra\nfree \"normal\" and \"safe\" page frames for two lists of PBEs constructed\nlater.\n\nNow, the image data are loaded, if possible, into their \"original\" page\nframes. The image data that cannot be written into their \"original\" page\nframes are loaded into \"safe\" page frames and their \"original\" kernel\nvirtual addresses, as well as the addresses of the \"safe\" pages containing\ntheir copies, are stored in one of two lists of PBEs.\n\nOne list of PBEs is for the copies of \"normal\" suspend pages (ie. \"normal\"\npages that were saveable during the suspend) and it is used in the same way\nas previously (ie. by the architecture-dependent parts of swsusp). The\nother list of PBEs is for the copies of highmem suspend pages.

From the swsusp\u0027s point of view (1) is not a problem,\n because it is already taken care of by the swap-handling code, but (2) has\n to be taken into consideration.\n\nIn principle the location of a swap file\u0027s header may be determined with the\nhelp of appropriate filesystem driver. Unfortunately, however, it requires\nthe filesystem holding the swap file to be mounted, and if this filesystem is\njournaled, it cannot be mounted during a resume from disk. For this reason we\nneed some other means by which swap areas can be identified.\n\nFor example, to identify a swap area we can use the partition that holds the\narea and the offset from the beginning of this partition at which the swap\nheader is located.\n\nThe following patch allows swsusp to identify swap areas this way. It changes\nswap_type_of() so that it takes an additional argument representing an offset\nof the swap header within the partition represented by its first argument.\n\nSigned-off-by: Rafael J.

However, GFP_THISNODE does not do reclaim (it wont do any at\nall if the recent GFP_THISNODE patch is accepted). If we truly run out of\nmemory in the whole system then fallback_alloc may return NULL although\nmemory may still be available if we would perform more thorough reclaim.\n\nThis patch changes fallback_alloc() so that we first only inspect all the\nper node queues for available slabs. If we find any then we allocate from\nthose. This avoids slab fragmentation by first getting rid of all partial\nallocated slabs on every node before allocating new memory.\n\nIf we cannot satisfy the allocation from any per node queue then we extend\na slab. We now call into the page allocator without specifying\nGFP_THISNODE. The page allocator will then implement its own fallback (in\nthe given cpuset context), perform necessary reclaim (again considering not\na single node but the whole set of allowed nodes) and then return pages for\na new slab.\n\nWe identify from which node the pages were allocated and then insert the\npages into the corresponding per node structure. In order to do so we need\nto modify cache_grow() to take a parameter that specifies the new slab.\nkmem_getpages() can no longer set the GFP_THISNODE flag since we need to be\nable to use kmem_getpage to allocate from an arbitrary node. GFP_THISNODE\nneeds to be specified when calling cache_grow().\n\nOne key advantage is that the decision from which node to allocate new\nmemory is removed from slab fallback processing.

(This test on 2,6.18 as 2.6.19-rc\ncrashes at __drain_pages\nhttp://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d116172164217678\u0026w\u003d2 )\n\nThe approach here is to hold cache_chain_mutex from CPU_UP_PREPARE until\nCPU_ONLINE (similar in approach as worqueue_mutex) . Slab code sensitive\nto cpu_online_map (kmem_cache_create, kmem_cache_destroy, slabinfo_write,\n__cache_shrink) is already serialized with cache_chain_mutex. (This patch\nlengthens cache_chain_mutex hold time at kmem_cache_destroy to cover this).\n This patch also takes the cache_chain_sem at kmem_cache_shrink to protect\nsanity of cpu_online_map at __cache_shrink, as viewed by slab.\n(kmem_cache_shrink-\u003e__cache_shrink-\u003edrain_cpu_caches). But, really,\nkmem_cache_shrink is used at just one place in the acpi subsystem! Do we\nreally need to keep kmem_cache_shrink at all?\n\nAnother note. Looks like a cpu hotplug event can send CPU_UP_CANCELED to\na registered subsystem even if the subsystem did not receive CPU_UP_PREPARE.\nThis could be due to a subsystem registered for notification earlier than\nthe current subsystem crapping out with NOTIFY_BAD. Badness can occur with\nin the CPU_UP_CANCELED code path at slab if this happens (The same would\napply for workqueue.c as well). To overcome this, we might have to use either\na) a per subsystem flag and avoid handling of CPU_UP_CANCELED, or\nb) Use a special notifier events like LOCK_ACQUIRE/RELEASE as Gautham was\n using in his experiments, or\nc) Do not send CPU_UP_CANCELED to a subsystem which did not receive\n CPU_UP_PREPARE.\n\nI would prefer c).\n\nSigned-off-by: Ravikiran Thirumalai \u003ckiran@scalex86.org\u003e\nSigned-off-by: Shai Fultheim \u003cshai@scalex86.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a44b56d354b49f9abb184e5a14f71889856283bb", "tree": "36eced3b179038a70463645395e6b31f3a5cc74c", "parents": [ "cace673d376d97b0c66ffa0a49b8d588a696d5d2" ], "author": { "name": "Kevin Hilman", "email": "khilman@mvista.com", "time": "Wed Dec 06 20:32:11 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 08:39:21 2006 -0800" }, "message": "[PATCH] slab debug and ARCH_SLAB_MINALIGN don\u0027t get along\n\nWhen CONFIG_SLAB_DEBUG is used in combination with ARCH_SLAB_MINALIGN, some\ndebug flags should be disabled which depend on BYTES_PER_WORD alignment.\n\nThe disabling of these debug flags is not properly handled when\nBYTES_PER_WORD \u003c ARCH_SLAB_MEMALIGN \u003c cache_line_size()\n\nThis patch fixes that and also adds an alignment check to\ncache_alloc_debugcheck_after() when ARCH_SLAB_MINALIGN is used.\n\nSigned-off-by: Kevin Hilman \u003ckhilman@mvista.com\u003e\nCc: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nCc: Christoph Lameter \u003cclameter@engr.sgi.com\u003e\nCc: Manfred Spraul \u003cmanfred@colorfullife.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "cace673d376d97b0c66ffa0a49b8d588a696d5d2", "tree": "c85c2ad65ad10132f00b484e91c8bfcd6e3f1afc", "parents": [ "39dde65c9940c97fcd178a3d2b1c57ed8b7b68aa" ], "author": { "name": "Chen, Kenneth W", "email": "kenneth.w.chen@intel.com", "time": "Wed Dec 06 20:32:07 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 08:39:21 2006 -0800" }, "message": "[PATCH] htlb forget rss with pt sharing\n\nImprecise RSS accounting is an irritating ill effect with pt sharing.

And it stashes a zone-to-node table in the zonelist struct,\nto optimize that conversion (minimize its cache footprint.)\n\nRecent changes:\n\n This differs in a significant way from a similar patch that I\n posted a week ago. Now, instead of having a nodemask_t of\n recently full nodes, I have a bitmask of recently full zones.\n This solves a problem that last weeks patch had, which on\n systems with multiple zones per node (such as DMA zone) would\n take seeing any of these zones full as meaning that all zones\n on that node were full.\n\n Also I changed names - from \"zonelist faster\" to \"zonelist cache\",\n as that seemed to better convey what we\u0027re doing here - caching\n some of the key zonelist state (for faster access.)\n\n See below for some performance benchmark results. After all that\n discussion with David on why I didn\u0027t need them, I went and got\n some ;). I wanted to verify that I had not hurt the normal case\n of memory allocation noticeably. At least for my one little\n microbenchmark, I found (1) the normal case wasn\u0027t affected, and\n (2) workloads that forced scanning across multiple nodes for\n memory improved up to 10% fewer System CPU cycles and lower\n elapsed clock time (\u0027sys\u0027 and \u0027real\u0027). Good. See details, below.\n\n I didn\u0027t have the logic in get_page_from_freelist() for various\n full nodes and zone reclaim failures correct. That should be\n fixed up now - notice the new goto labels zonelist_scan,\n this_zone_full, and try_next_zone, in get_page_from_freelist().\n\nThere are two reasons I persued this alternative, over some earlier\nproposals that would have focused on optimizing the fake numa\nemulation case by caching the last useful zone:\n\n 1) Contrary to what I said before, we (SGI, on large ia64 sn2 systems)\n have seen real customer loads where the cost to scan the zonelist\n was a problem, due to many nodes being full of memory before\n we got to a node we could use. Or at least, I think we have.\n This was related to me by another engineer, based on experiences\n from some time past. So this is not guaranteed. Most likely, though.\n\n The following approach should help such real numa systems just as\n much as it helps fake numa systems, or any combination thereof.\n\n 2) The effort to distinguish fake from real numa, using node_distance,\n so that we could cache a fake numa node and optimize choosing\n it over equivalent distance fake nodes, while continuing to\n properly scan all real nodes in distance order, was going to\n require a nasty blob of zonelist and node distance munging.\n\n The following approach has no new dependency on node distances or\n zone sorting.\n\nSee comment in the patch below for a description of what it actually does.\n\nTechnical details of note (or controversy):\n\n - See the use of \"zlc_active\" and \"did_zlc_setup\" below, to delay\n adding any work for this new mechanism until we\u0027ve looked at the\n first zone in zonelist. I figured the odds of the first zone\n having the memory we needed were high enough that we should just\n look there, first, then get fancy only if we need to keep looking.\n\n - Some odd hackery was needed to add items to struct zonelist, while\n not tripping up the custom zonelists built by the mm/mempolicy.c\n code for MPOL_BIND. My usual wordy comments below explain this.\n Search for \"MPOL_BIND\".\n\n - Some per-node data in the struct zonelist is now modified frequently,\n with no locking. Multiple CPU cores on a node could hit and mangle\n this data. The theory is that this is just performance hint data,\n and the memory allocator will work just fine despite any such mangling.\n The fields at risk are the struct \u0027zonelist_cache\u0027 fields \u0027fullzones\u0027\n (a bitmask) and \u0027last_full_zap\u0027 (unsigned long jiffies). It should\n all be self correcting after at most a one second delay.\n\n - This still does a linear scan of the same lengths as before.

We seem, at least in the fake numa case, to have put the\n lie to that claim.\n\n - I pay no attention to the various watermarks and such in this performance\n hint. A node could be marked full for one watermark, and then skipped\n over when searching for a page using a different watermark.

The \u0027sys\u0027 and \u0027user\u0027 columns are total\n CPU seconds spent on that test pass. For a 19 thread test run,\n for example, the sum of \u0027sys\u0027 and \u0027user\u0027 could be up to 19 times the\n number of \u0027real\u0027 elapsed wall clock seconds.\n\n 3) Tests were run on a fresh, single-user boot, to minimize the amount\n of memory already in use at the start of the test, and to minimize\n the amount of background activity that might interfere.\n\n 4) Tests were done on a 56 CPU, 28 Node system with 96 GBytes of RAM.\n\n 5) Notice that the \u0027real\u0027 time gets large for the single thread runs, even\n though the measured \u0027sys\u0027 and \u0027user\u0027 times are modest. I\u0027m not sure what\n that means - probably something to do with it being slow for one thread to\n be accessing memory along ways away. Perhaps the fake numa system, running\n ostensibly the same workload, would not show this substantial degradation\n of \u0027real\u0027 time for one thread on many nodes -- lets hope not.\n\n 6) The high thread count passes (one thread per CPU - on 55 of 56 CPUs)\n ran quite efficiently, as one might expect. Each pair of threads needed\n to allocate and touch the memory on the node the two threads shared, a\n pleasantly parallizable workload.\n\n 7) The intermediate thread count passes, when asking for alot of memory forcing\n them to go to a few neighboring nodes, improved the most with this zonelist\n caching patch.\n\nConclusions:\n * This zonelist cache patch probably makes little difference one way or the\n other for most workloads on real numa hardware, if those workloads avoid\n heavy off node allocations.\n * For memory intensive workloads requiring substantial off-node allocations\n on real numa hardware, this patch improves both kernel and elapsed timings\n up to ten per-cent.\n * For fake numa systems, I\u0027m optimistic, but will have to leave that up to\n Rohit Seth to actually test (once I get him a 2.6.18 backport.)\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nCc: Rohit Seth \u003crohitseth@google.com\u003e\nCc: Christoph Lameter \u003cclameter@engr.sgi.com\u003e\nCc: David Rientjes \u003crientjes@cs.washington.edu\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "89689ae7f95995723fbcd5c116c47933a3bb8b13", "tree": "4d73ff59b557fa1a84c6064406ff101c76ff8adc", "parents": [ "c0a499c2c42992cff097b38be29d2ba60d2fd99a" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Wed Dec 06 20:31:45 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 08:39:20 2006 -0800" }, "message": "[PATCH] Get rid of zone_table[]\n\nThe zone table is mostly not needed.

In all of\nthe above cases there will be no need at all for the zone table.\n\nThe only remaining case is if in a NUMA system the node numbers do not fit\ninto the page flags.
