For\nexample i386 and x86_64 have 16M DMA zones and either 900M ZONE_NORMAL or\nZONE_DMA32. These are even present on SMP and NUMA systems.\n\nThe patch here sets up a threshold based on the number of processors in the\nsystem and the size of the zone that these counters are used for.

This single instruction is atomic for i386 and x86_64.\n And therefore even the rare race condition in an interrupt is avoided for\nboth architectures in most cases.\n\nThe patchset also adds an off switch for embedded systems that allows a\nbuilding of linux kernels without these counters.\n\nThe implementation of these counters is through inline code that hopefully\nresults in only a single instruction increment instruction being emitted\n(i386, x86_64) or in the increment being hidden though instruction\nconcurrency (EPIC architectures such as ia64 can get that done).\n\nBenefits:\n- VM event counter operations usually reduce to a single inline instruction\n on i386 and x86_64.\n- No interrupt disable, only preempt disable for the preempt case.\n Preempt disable can also be avoided by moving the counter into a spinlock.\n- Handling is similar to zoned VM counters.\n- Simple and easily extendable.\n- Can be omitted to reduce memory use for embedded use.\n\nReferences:\n\nRFC http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113512330605497\u0026w\u003d2\nRFC http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d114988082814934\u0026w\u003d2\nlocal_t http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d114991748606690\u0026w\u003d2\nV2 http://marc.theaimsgroup.com/?t\u003d115014808400007\u0026r\u003d1\u0026w\u003d2\nV3 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115024767022346\u0026w\u003d2\nV4 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115047968808926\u0026w\u003d2\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "ca889e6c45e0b112cb2ca9d35afc66297519b5d5", "tree": "0a5efdec2a61540204d34bcbf56dc691d8f9c391", "parents": [ "bab1846a0582f627f5ec22aa2dc5f4f3e82e8176" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Fri Jun 30 01:55:44 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 30 11:25:36 2006 -0700" }, "message": "[PATCH] Use Zoned VM Counters for NUMA statistics\n\nThe numa statistics are really event counters.

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. This patch provides\n some of the needed numbers.\n\n- Detailed VM counters available in more /proc and /sys status files.\n\nReferences to earlier discussions:\nV1 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113511649910826\u0026w\u003d2\nV2 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d114980851924230\u0026w\u003d2\nV3 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115014697910351\u0026w\u003d2\nV4 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115024767318740\u0026w\u003d2\n\nPerformance tests with AIM7 did not show any regressions.

It uses copy_from_user_atomic rather than copy_from_user\nso the simple expedient is to change copy_from_user_atomic to *not* zero out\nbytes on failure.\n\nThe first of these two patches prepares for the change by fixing two places\nwhich assume copy_from_user_atomic does zero the tail. The two usages are\nvery similar pieces of code which copy from a userspace iovec into one or more\npage-cache pages. These are changed to remove the assumption.\n\nThe second patch changes __copy_from_user_inatomic* to not zero the tail.\nOnce these are accepted, I will look at similar patches of other architectures\nwhere this is important (ppc, mips and sparc being the ones I can find).\n\nThis patch:\n\nThere is a problem with __copy_from_user_inatomic zeroing the tail of the\nbuffer in the case of an error. As it is called in atomic context, the error\nmay be transient, so it results in zeros being written where maybe they\nshouldn\u0027t be.\n\nIn the usage in filemap, this opens a window for a well timed read to see data\n(zeros) which is not consistent with any ordering of reads and writes.\n\nMost cases where __copy_from_user_inatomic is called, a failure results in\n__copy_from_user being called immediately. As long as the latter zeros the\ntail, the former doesn\u0027t need to. However in *copy_from_user_iovec\nimplementations (in both filemap and ntfs/file), it is assumed that\ncopy_from_user_inatomic will zero the tail.\n\nThis patch removes that assumption, so that after this patch it will\nbe safe for copy_from_user_inatomic to not zero the tail.\n\nThis patch also adds some commentary to filemap.h and asm-i386/uaccess.h.\n\nAfter this patch, all architectures that might disable preempt when\nkmap_atomic is called need to have their __copy_from_user_inatomic* \"fixed\".\nThis includes\n - powerpc\n - i386\n - mips\n - sparc\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Anton Altaparmakov \u003caia21@cantab.net\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "43b0bc00fdbf2f1503a57f0c2c1338438c5d2805", "tree": "1009ac1c764b21c50f96e2a108a2736504d9588a", "parents": [ "dc851a0fd2736e8dc3e90bd990cb911a0013da67" ], "author": { "name": "Chris Wright", "email": "chrisw@sous-sol.org", "time": "Sun Jun 25 05:47:55 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jun 25 10:01:08 2006 -0700" }, "message": "[PATCH] cpuset: remove extra cpuset_zone_allowed check in __alloc_pages\n\nThis is redundant with check in wakeup_kswapd.\n\nSigned-off-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nAcked-by: Paul Jackson \u003cpj@sgi.com\u003e\nAcked-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d616e09ab33aa4d013a93c9b393efd5cebf78521", "tree": "13837ef8dc9e955c621d798235c064218b56361d", "parents": [ "bc64863814b14a4f75884746e68d3bf9f96b3559" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Sun Jun 25 05:47:46 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jun 25 10:01:06 2006 -0700" }, "message": "[PATCH] pdflush: handle resume wakeups\n\npdflush is carefully designed to ensure that all wakeups have some\ncorresponding work to do - if a woken-up pdflush thread discovers that it\nhasn\u0027t been given any work to do then this is considered an error.\n\nThat all broke when swsusp came along - because a timer-delivered wakeup to a\nfrozen pdflush thread will just get lost.

For io schedulers such as CFQ,\nthis will cause us lost merges and suboptimal behaviour in scheduling.\n\nRemove PF_SYNCWRITE completely from the fsync/msync paths, and let\nthe O_DIRECT path just directly indicate that the writes are sync\nby using WRITE_SYNC instead.\n\nSigned-off-by: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "125e18745f16685f69a34fd6130d47598fc4bf54", "tree": "c97ed94b0525a572efa1bd4990a55b18be5d781d", "parents": [ "78ce89c92bc6eaf5933b5664bff64253a7103bd7" ], "author": { "name": "Eric Sesterhenn", "email": "snakebyte@gmx.de", "time": "Fri Jun 23 02:06:06 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 23 07:43:08 2006 -0700" }, "message": "[PATCH] More BUG_ON conversion\n\nSigned-off-by: Eric Sesterhenn \u003csnakebyte@gmx.de\u003e\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nCc: Bartlomiej Zolnierkiewicz \u003cB.Zolnierkiewicz@elka.pw.edu.pl\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: James Bottomley \u003cJames.Bottomley@steeleye.com\u003e\nAcked-by: \"Salyzyn, Mark\" \u003cmark_salyzyn@adaptec.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" } ], "next": "e0f23603fb2607315ce52432cc4225df410828cf" }
