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. The pages\nin this list are restored (in a reversible way) right before the\narch-dependent code is called.\n\nSigned-off-by: Rafael J.

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.

This\nset of patch target shared page table for hugetlb memory only.\n\nThe shared page table is particular useful in the situation of large number of\nindependent processes sharing large shared memory segments. In the normal\npage case, the amount of memory saved from process\u0027 page table is quite\nsignificant. For hugetlb, the saving on page table memory is not the primary\nobjective (as hugetlb itself already cuts down page table overhead\nsignificantly), instead, the purpose of using shared page table on hugetlb is\nto allow faster TLB refill and smaller cache pollution upon TLB miss.\n\nWith PT sharing, pte entries are shared among hundreds of processes, the cache\nconsumption used by all the page table is smaller and in return, application\ngets much higher cache hit ratio. One other effect is that cache hit ratio\nwith hardware page walker hitting on pte in cache will be higher and this\nhelps to reduce tlb miss latency.

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. All\n I\u0027ve optimized is making the scan faster, not algorithmically\n shorter. It is now able to scan a compact array of \u0027unsigned\n short\u0027 in the case of many full nodes, so one cache line should\n cover quite a few nodes, rather than each node hitting another\n one or two new and distinct cache lines.\n\n - If both Andi and Nick don\u0027t find this too complicated, I will be\n (pleasantly) flabbergasted.\n\n - I removed the comment claiming we only use one cachline\u0027s worth of\n zonelist. 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. I think\n that\u0027s actually quite ok, as it will tend to slightly increase the\n spreading of memory over other nodes, away from a memory stressed node.\n\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nPerformance - some benchmark results and analysis:\n\nThis benchmark runs a memory hog program that uses multiple\nthreads to touch alot of memory as quickly as it can.\n\nMultiple runs were made, touching 12, 38, 64 or 90 GBytes out of\nthe total 96 GBytes on the system, and using 1, 19, 37, or 55\nthreads (on a 56 CPU system.)

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 balance_pgdat, we keep a separate\npriority record per zone in a local array. In try_to_free_pages there is\nno need to do this, as the priority level is the same for all zones that we\nreclaim from.\n\nImpact of this bug is that temp_priority is copied into prev_priority, and\nsetting this artificially high causes reclaimers to set distress\nartificially low.

We simply use the\ninode number and generation number to construct the filehandle.\n\nThe generation number is the time when the file was created. As inode numbers\ncycle through the full 32 bits before being reused, there is no real chance of\nthe same inum being allocated to different files in the same second so this is\nsuitably unique. Using time-of-day rather than e.g. jiffies makes it less\nlikely that the same filehandle can be created after a reboot.\n\nIn order to be able to decode a filehandle we need to be able to lookup by\ninum, which means that the inode needs to be added to the inode hash table\n(tmpfs doesn\u0027t currently hash inodes as there is never a need to lookup by\ninum). To avoid overhead when not exporting, we only hash an inode when it is\nfirst exported. This requires a lock to ensure it isn\u0027t hashed twice.\n\nThis code is separate from the patch posted in June06 from Atal Shargorodsky\nwhich provided the same functionality, but does borrow slightly from it.\n\nLocking comment: Most filesystems that hash their inodes do so at the point\nwhere the \u0027struct inode\u0027 is initialised, and that has suitable locking\n(I_NEW). Here in shmem, we are hashing the inode later, the first time we\nneed an NFS file handle for it.

Basically, that provides a generic solution\nfor being able to have no_page() map hardware devices, which is something that\nI think sound driver folks have been asking for some time too).\n\nAll of these things depend on having the NOPAGE_REFAULT exit path from\nno_page() handlers.\n\nSigned-off-by: Benjamin Herrenchmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1ca4cb2418c04914e4661c059cf5b7b9262c645a", "tree": "add7a43542be686a552dfc48754a540fb721f811", "parents": [ "da66b719d16f6ea3801b859c1ff35d5cd05c517d" ], "author": { "name": "Pekka Enberg", "email": "penberg@cs.helsinki.fi", "time": "Fri Oct 06 00:43:52 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Oct 06 08:53:40 2006 -0700" }, "message": "[PATCH] slab: reduce numa text size\n\nReduce the NUMA text size of mm/slab.o a little on x86 by using a local\nvariable to store the result of numa_node_id().\n\n text data bss dec hex filename\n 16858 2584 16 19458 4c02 mm/slab.o (before)\n 16804 2584 16 19404 4bcc mm/slab.o (after)\n\n[akpm@osdl.org: use better names]\n[pbadari@us.ibm.com: fix that]\nCc: Christoph Lameter \u003cchristoph@lameter.com\u003e\nSigned-off-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nSigned-off-by: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "fefd26b3b8597a11a422d950c0d4424ff33a70ad", "tree": "6794a36072635e71e5b33aec47c616bafdca65c1", "parents": [ "4a61f17378c2cdd9bd8f34ef8bd7422861d0c1f1", "038b0a6d8d32db934bba6a24e74e76e4e327a94f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 09:59:57 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 09:59:57 2006 -0700" }, "message": "Merge master.kernel.org:/pub/scm/linux/kernel/git/davej/configh\n\n* master.kernel.org:/pub/scm/linux/kernel/git/davej/configh:\n Remove all inclusions of \u003clinux/config.h\u003e\n\nManually resolved trivial path conflicts due to removed files in\nthe sound/oss/ subdirectory.\n" }, { "commit": "4a61f17378c2cdd9bd8f34ef8bd7422861d0c1f1", "tree": "a2054556900af8c16fd9f5419f012dcf1ee2995a", "parents": [ "d002ec481c24f325ed6cfcb7810d317c015dd1b5", "7ecdb70a0ea436c06540140242bfac6ac3babfc0" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 09:06:16 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 09:06:16 2006 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-2.6: (292 commits)\n [GFS2] Fix endian bug for de_type\n [GFS2] Initialize SELinux extended attributes at inode creation time.\n [GFS2] Move logging code into log.c (mostly)\n [GFS2] Mark nlink cleared so VFS sees it happen\n [GFS2] Two redundant casts removed\n [GFS2] Remove uneeded endian conversion\n [GFS2] Remove duplicate sb reading code\n [GFS2] Mark metadata reads for blktrace\n [GFS2] Remove iflags.h, use FS_\n [GFS2] Fix code style/indent in ops_file.c\n [GFS2] streamline-generic_file_-interfaces-and-filemap gfs fix\n [GFS2] Remove readv/writev methods and use aio_read/aio_write instead (gfs bits)\n [GFS2] inode-diet: Eliminate i_blksize from the inode structure\n [GFS2] inode_diet: Replace inode.u.generic_ip with inode.i_private (gfs)\n [GFS2] Fix typo in last patch\n [GFS2] Fix direct i/o logic in filemap.c\n [GFS2] Fix bug in Makefiles for lock modules\n [GFS2] Remove (extra) fs_subsys declaration\n [GFS2/DLM] Fix trailing whitespace\n [GFS2] Tidy up meta_io code\n ...\n" }, { "commit": "1d2c8eea698514cfaa53fc991b960791d09508e1", "tree": "e6e2b2d491e7e7256862fcc493b81815cc966312", "parents": [ "88ca3b94e82e763ef90c8e57cacd51a3c143ea62" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed Oct 04 02:15:25 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Oct 04 07:55:13 2006 -0700" }, "message": "[PATCH] slab: clean up leak tracking ifdefs a little bit\n\n- rename ____kmalloc to kmalloc_track_caller so that people have a chance\n to guess what it does just from it\u0027s name.
