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.

This way, the condition to check whether to pre-empt the swap\ntoken, is a matter of comparing two task\u0027s priority fields.\n\n[akpm@osdl.org: cleanups]\nSigned-off-by: Ashwin Chaugule \u003cashwin.chaugule@celunite.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "098fe651f7e9d759d1117c78c1a642b9b3945922", "tree": "8688e367d04c8341e79d9da775dccb9dc7747509", "parents": [ "cd54e7e54318d333227b13186f9a464bf1f68d27" ], "author": { "name": "Ashwin Chaugule", "email": "ashwin.chaugule@celunite.com", "time": "Wed Dec 06 20:31:54 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 08:39:21 2006 -0800" }, "message": "[PATCH] grab swap token reordered\n\nMake sure the contention for the token happens _before_ any read-in and\nkicks the swap-token algo only when the VM is under pressure.\n\nSigned-off-by: Ashwin Chaugule \u003cashwin.chaugule@celunite.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "cd54e7e54318d333227b13186f9a464bf1f68d27", "tree": "75bf795ab6c3805f318b2d3040321ba31ef35c6a", "parents": [ "f2a2a7108aa0039ba7a5fe7a0d2ecef2219a7584" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Wed Dec 06 20:31:53 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 08:39:20 2006 -0800" }, "message": "[PATCH] mm: incorrect VM_FAULT_OOM returns from drivers\n\nSome drivers are returning OOM when it is not in response to a memory\nshortage.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Dave Airlie \u003cairlied@linux.ie\u003e\nCc: Jaroslav Kysela \u003cperex@suse.cz\u003e\nCc: Takashi Iwai \u003ctiwai@suse.de\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f2a2a7108aa0039ba7a5fe7a0d2ecef2219a7584", "tree": "a82338b774d680ca410830e94c1125fa3b9b693d", "parents": [ "f3af38d30c18538d069a95e624a3db7c3d486a1e" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Wed Dec 06 20:31:52 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 08:39:20 2006 -0800" }, "message": "[PATCH] oom: less memdie\n\nDon\u0027t cause all threads in all other thread groups to gain TIF_MEMDIE\notherwise we\u0027ll get a thundering herd eating our memory reserve.

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.

The main benefit is to\nreduce the cache foootprint of the VM from the frequent lookups of zones.\nPlus it simplifies the page allocator.\n\n[akpm@osdl.org: build fix]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c0a499c2c42992cff097b38be29d2ba60d2fd99a", "tree": "e02e80f190eb6f4eedb2c991d92840137505f8f8", "parents": [ "0798e5193cd70f6c867ec176d7730589f944c627" ], "author": { "name": "Chen, Kenneth W", "email": "kenneth.w.chen@intel.com", "time": "Wed Dec 06 20:31:39 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 08:39:20 2006 -0800" }, "message": "[PATCH] __unmap_hugepage_range(): add comment\n\nSigned-off-by: Ken Chen \u003ckenneth.w.chen@intel.com\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0798e5193cd70f6c867ec176d7730589f944c627", "tree": "abe3ada0b04080729418a0c301d8b55b4363b56e", "parents": [ "a2ce774096110ccc5c02cbdc05897d005fcd3db8" ], "author": { "name": "Paul Jackson", "email": "pj@sgi.com", "time": "Wed Dec 06 20:31:38 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Thu Dec 07 08:39:20 2006 -0800" }, "message": "[PATCH] memory page alloc minor cleanups\n\n- s/freeliest/freelist/ spelling fix\n\n- Check for NULL *z zone seems useless - even if it could happen, so\n what?
