Before the change new areas were always\n searched from the base address on.\n\n So now new small areas are cluttering holes of all sizes\n throughout the whole mmap-able region whereas before small holes\n tended to close holes near the base leaving holes far from the base\n large and available for larger requests.\n\n 2) the free_area_cache also is set to the location of the last\n munmap-ed area so in scenarios where we allocate e.g. five regions of\n 1K each, then free regions 4 2 3 in this order the next request for 1K\n will be placed in the position of the old region 3, whereas before we\n appended it to the still active region 1, placing it at the location\n of the old region 2. Before we had 1 free region of 2K, now we only\n get two free regions of 1K -\u003e fragmentation.\n\nThe patch addresses thes issues by introducing yet another cache descriptor\ncached_hole_size that contains the largest known hole size below the\ncurrent free_area_cache. If a new request comes in the size is compared\nagainst the cached_hole_size and if the request can be filled with a hole\nbelow free_area_cache the search is started from the base instead.\n\nThe results look promising: Whereas 2.6.12-rc4 fragments quickly and my\n(earlier posted) leakme.c test program terminates after 50000+ iterations\nwith 96 distinct and fragmented maps in /proc/self/maps it performs nicely\n(as expected) with thread creation, Ingo\u0027s test_str02 with 20000 threads\nrequires 0.7s system time.\n\nTaking out Ingo\u0027s patch (un-patch available per request) by basically\ndeleting all mentions of free_area_cache from the kernel and starting the\nsearch for new memory always at the respective bases we observe: leakme\nterminates successfully with 11 distinctive hardly fragmented areas in\n/proc/self/maps but thread creating is gringdingly slow: 30+s(!) system\ntime for Ingo\u0027s test_str02 with 20000 threads.\n\nNow - drumroll ;-) the appended patch works fine with leakme: it ends with\nonly 7 distinct areas in /proc/self/maps and also thread creation seems\nsufficiently fast with 0.71s for 20000 threads.\n\nSigned-off-by: Wolfgang Wander \u003cwwc@rentec.com\u003e\nCredit-to: \"Richard Purdie\" \u003crpurdie@rpsys.net\u003e\nSigned-off-by: Ken Chen \u003ckenneth.w.chen@intel.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e (partly)\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "63551ae0feaaa23807ebea60de1901564bbef32e", "tree": "f6f97f60f83c3e9813bdfcc6039c499997b1ea10", "parents": [ "1e7e5a9048b30c57ba1ddaa6cdf59b21b65cde99" ], "author": { "name": "David Gibson", "email": "david@gibson.dropbear.id.au", "time": "Tue Jun 21 17:14:44 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Tue Jun 21 18:46:15 2005 -0700" }, "message": "[PATCH] Hugepage consolidation\n\nA lot of the code in arch/*/mm/hugetlbpage.c is quite similar.

The end result is that each fault takes longer when\nthere\u0027s contention, which in turn increases the chance of another thread\nhitting the same fault and also piling up. Not pretty.\n\nThere\u0027s two options here:\n1. Do an out-of-line busy loop a\u0027la spinlocks with just loads (no\n reserves)\n2. Just bail and refault if needed.\n\n(2) makes sense here: If the PTE is busy, chances are it\u0027s in flux anyway\nand the other code path making a change might just be ready to hash it.\n\nThis fixes a stampede seen on a large-ish system where a multithreaded\nHPC app faults in the same text pages on several cpus at the same time.\n\nSigned-off-by: Olof Johansson \u003colof@lixom.net\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "58366af5861eee1479426380e3c91ecb334c301d", "tree": "2c7e61d424279057ebeb2ef32b2e9648666848ca", "parents": [ "0339ad77c4a06fa8529db17c91f790058e18b65b" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Sun May 01 08:58:44 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sun May 01 08:58:44 2005 -0700" }, "message": "[PATCH] ppc64: update to use the new 4L headers\n\nThis patch converts ppc64 to use the generic pgtable-nopud.h instead of the\n\"fixup\" header.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "bb78cb72201985ae9269b723c82ea0f892048b9e", "tree": "e956a4c1647e79a9b39d0cb1dfa6f6f60c4f9af1", "parents": [ "1b29f9d13e3cf0fe86bf7f82a3399c9e3caf58e5" ], "author": { "name": "Olof Johansson", "email": "olof@austin.ibm.com", "time": "Sun May 01 08:58:44 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sun May 01 08:58:44 2005 -0700" }, "message": "[PATCH] ppc64: remove unused argument to create_slbe\n\nRemove vsid argument to create_slbe, since it\u0027s no longer used.\n\nSpotted by R Sharada.\n\nSigned-off-by: Olof Johansson \u003colof@austin.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "021740dc30d184e3b0fa7679936e65a56090c425", "tree": "c31bd23fe74038b4bab5148e17e07745b75b453d", "parents": [ "146425a316fb937fbdcac018b34a23c67d12214b" ], "author": { "name": "Hugh Dickins", "email": "hugh@veritas.com", "time": "Tue Apr 19 13:29:18 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org.(none)", "time": "Tue Apr 19 13:29:18 2005 -0700" }, "message": "[PATCH] freepgt: hugetlb area is clean\n\nOnce we\u0027re strict about clearing away page tables, hugetlb_prefault can assume\nthere are no page tables left within its range.

Since ia64 does need a special case, restore to\nppc64 the special case of skipping them.\n\nThe ia64 hugetlb case has been broken since pgd_addr_end went in, though it\nprobably appeared to work okay if you just had one such area; in fact it\u0027s\nbeen broken much longer if you consider a long munmap spanning from another\nregion into the hugetlb region.\n\nIn the ia64 hugetlb region, more virtual address bits are available than in\nthe other regions, yet the page tables are structured the same way: the page\nat the bottom is larger.
