API\n\nTwo new functions are added to kprobes:\n\n\tint register_kretprobe(struct kretprobe *rp);\n\tvoid unregister_kretprobe(struct kretprobe *rp);\n\n2. Registration and unregistration\n\n2.1 Register\n\n To register a function-return probe, the user populates the following\n fields in a kretprobe object and calls register_kretprobe() with the\n kretprobe address as an argument:\n\n kp.addr - the function\u0027s address\n\n handler - this function is run after the ret instruction executes, but\n before control returns to the return address in the caller.\n\n maxactive - The maximum number of instances of the probed function that\n can be active concurrently. For example, if the function is non-\n recursive and is called with a spinlock or mutex held, maxactive \u003d 1\n should be enough. If the function is non-recursive and can never\n relinquish the CPU (e.g., via a semaphore or preemption), NR_CPUS should\n be enough. maxactive is used to determine how many kretprobe_instance\n objects to allocate for this particular probed function. If maxactive \u003c\u003d\n 0, it is set to a default value (if CONFIG_PREEMPT maxactive\u003dmax(10, 2 *\n NR_CPUS) else maxactive\u003dNR_CPUS)\n\n For example:\n\n struct kretprobe rp;\n rp.kp.addr \u003d /* entrypoint address */\n rp.handler \u003d /*return probe handler */\n rp.maxactive \u003d /* e.g., 1 or NR_CPUS or 0, see the above explanation */\n register_kretprobe(\u0026rp);\n\n The following field may also be of interest:\n\n nmissed - Initialized to zero when the function-return probe is\n registered, and incremented every time the probed function is entered but\n there is no kretprobe_instance object available for establishing the\n function-return probe (i.e., because maxactive was set too low).\n\n2.2 Unregister\n\n To unregiter a function-return probe, the user calls\n unregister_kretprobe() with the same kretprobe object as registered\n previously. If a probed function is running when the return probe is\n unregistered, the function will return as expected, but the handler won\u0027t\n be run.\n\n3. Limitations\n\n3.1 This patch supports only the i386 architecture, but patches for\n x86_64 and ppc64 are anticipated soon.\n\n3.2 Return probes operates by replacing the return address in the stack\n (or in a known register, such as the lr register for ppc). This may\n cause __builtin_return_address(0), when invoked from the return-probed\n function, to return the address of the return-probes trampoline.\n\n3.3 This implementation uses the \"Multiprobes at an address\" feature in\n 2.6.12-rc3-mm3.\n\n3.4 Due to a limitation in multi-probes, you cannot currently establish\n a return probe and a jprobe on the same function. A patch to remove\n this limitation is being tested.\n\nThis feature is required by SystemTap (http://sourceware.org/systemtap),\nand reflects ideas contributed by several SystemTap developers, including\nWill Cohen and Ananth Mavinakayanahalli.\n\nSigned-off-by: Hien Nguyen \u003chien@us.ibm.com\u003e\nSigned-off-by: Prasanna S Panchamukhi \u003cprasanna@in.ibm.com\u003e\nSigned-off-by: Frederik Deweerdt \u003cfrederik.deweerdt@laposte.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "84de856ed30c568c2bb7b9ac0679772bd2737d9b", "tree": "532e4f6bcc0db2d1baf0455484ec7f64a2a51e71", "parents": [ "df164db5fd16888ddbe2a63a47b2f6dda9a428b5" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Thu Jun 23 00:09:16 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:20 2005 -0700" }, "message": "[PATCH] quota: consolidate code surrounding vfs_quota_on_mount\n\nMove some code duplicated in both callers into vfs_quota_on_mount\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nAcked-by: Jan Kara \u003cjack@ucw.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "ac20427ef6aa63da663bdc88b71d16f7394f5e23", "tree": "49ba4f88c5cea42d59b386c508174f585efc8a01", "parents": [ "3bc1ee3e8f1c05c0f64a479c6d56eb34a6190599" ], "author": { "name": "Neil Horman", "email": "nhorman@redhat.com", "time": "Thu Jun 23 00:09:11 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:19 2005 -0700" }, "message": "[PATCH] add check to /proc/devices read routines\n\nPatch to add check to get_chrdev_list and get_blkdev_list to prevent reads\nof /proc/devices from spilling over the provided page if more than 4096\nbytes of string data are generated from all the registered character and\nblock devices in a system\n\nSigned-off-by: Neil Horman \u003cnhorman@redhat.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: \u003cviro@parcelfarce.linux.theplanet.co.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "35a82d1a53e1a9ad54efafcc940f9335beaed5c3", "tree": "776d5b01970c5ce3e2c9fd4a2c4cf2168a0afa3c", "parents": [ "ab4af03a4054bd78bcabfb2214c9597201beae35" ], "author": { "name": "Nick Piggin", "email": "nickpiggin@yahoo.com.au", "time": "Thu Jun 23 00:09:06 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:18 2005 -0700" }, "message": "[PATCH] optimise loop driver a bit\n\nLooks like locking can be optimised quite a lot.

The timer can be fired again after\n del_timer_sync have checked all cpus and before it will recheck\n timer_pending().\n\n2. It has scalability problems. All cpus are scanned to determine\n if the timer is running on that cpu.\n\n With this patch del_timer_sync is O(1) and no slower than plain\n del_timer(pending_timer), unless it has to actually wait for\n completion of the currently running timer.\n\n The only restriction is that the recurring timer should not use\n add_timer_on().\n\n3. The timers are not serialized wrt to itself.\n\n If CPU_0 does mod_timer(jiffies+1) while the timer is currently\n running on CPU 1, it is quite possible that local interrupt on\n CPU_0 will start that timer before it finished on CPU_1.\n\n4. The timers locking is suboptimal. __mod_timer() takes 3 locks\n at once and still requires wmb() in del_timer/run_timers.\n\n The new implementation takes 2 locks sequentially and does not\n need memory barriers.\n\nCurrently -\u003ebase !\u003d NULL means that the timer is pending. In that case\n-\u003ebase.lock is used to lock the timer. __mod_timer also takes timer-\u003elock\nbecause -\u003ebase can be \u003d\u003d NULL.\n\nThis patch uses timer-\u003eentry.next !\u003d NULL as indication that the timer is\npending. So it does __list_del(), entry-\u003enext \u003d NULL instead of list_del()\nwhen the timer is deleted.\n\nThe -\u003ebase field is used for hashed locking only, it is initialized\nin init_timer() which sets -\u003ebase \u003d per_cpu(tvec_bases). When the\ntvec_bases.lock is locked, it means that all timers which are tied\nto this base via timer-\u003ebase are locked, and the base itself is locked\ntoo.\n\nSo __run_timers/migrate_timers can safely modify all timers which could\nbe found on -\u003etvX lists (pending timers).\n\nWhen the timer\u0027s base is locked, and the timer removed from -\u003eentry list\n(which means that _run_timers/migrate_timers can\u0027t see this timer), it is\npossible to set timer-\u003ebase \u003d NULL and drop the lock: the timer remains\nlocked.\n\nThis patch adds lock_timer_base() helper, which waits for -\u003ebase !\u003d NULL,\nlocks the -\u003ebase, and checks it is still the same.\n\n__mod_timer() schedules the timer on the local CPU and changes it\u0027s base.\nHowever, it does not lock both old and new bases at once. It locks the\ntimer via lock_timer_base(), deletes the timer, sets -\u003ebase \u003d NULL, and\nunlocks old base. Then __mod_timer() locks new_base, sets -\u003ebase \u003d new_base,\nand adds this timer. This simplifies the code, because AB-BA deadlock is not\npossible. __mod_timer() also ensures that the timer\u0027s base is not changed\nwhile the timer\u0027s handler is running on the old base.\n\n__run_timers(), del_timer() do not change -\u003ebase anymore, they only clear\npending flag.\n\nSo del_timer_sync() can test timer-\u003ebase-\u003erunning_timer \u003d\u003d timer to detect\nwhether it is running or not.\n\nWe don\u0027t need timer_list-\u003elock anymore, this patch kills it.\n\nWe also don\u0027t need barriers. del_timer() and __run_timers() used smp_wmb()\nbefore clearing timer\u0027s pending flag. It was needed because __mod_timer()\ndid not lock old_base if the timer is not pending, so __mod_timer()-\u003elist_add()\ncould race with del_timer()-\u003elist_del(). With this patch these functions are\nserialized through base-\u003elock.\n\nOne problem. TIMER_INITIALIZER can\u0027t use per_cpu(tvec_bases). So this patch\nadds global\n\n struct timer_base_s {\n spinlock_t lock;\n struct timer_list *running_timer;\n } __init_timer_base;\n\nwhich is used by TIMER_INITIALIZER. The corresponding fields in tvec_t_base_s\nstruct are replaced by struct timer_base_s t_base.\n\nIt is indeed ugly. But this can\u0027t have scalability problems. The global\n__init_timer_base.lock is used only when __mod_timer() is called for the first\ntime AND the timer was compile time initialized.

It changes behavior so that there is a call to\npfn_to_page() for each individual page inside of a node\u0027s range:\nnode_start_pfn through node_end_pfn. It used to simply do this once, at the\nbeginning of the node, but having sparsemem\u0027s non-contiguous mem_map[]s inside\nof a node made it necessary to change.\n\nMike Kravetz recently wrote a patch which made the NUMA code accept some new\nkinds of layouts. The system\u0027s memory was laid out like this, with node 0\u0027s\nmemory in two pieces: one before and one after node 1\u0027s memory:\n\n\tNode 0: +++++ +++++\n\tNode 1: +++++\n\nPrevious behavior before Mike\u0027s patch was to assign nodes like this:\n\n\tNode 0: 00000 XXXXX\n\tNode 1: 11111\n\nWhere the \u0027X\u0027 areas were simply thrown away. The new behavior was to make the\npg_data_t span node 0 across all of its areas, including areas that are really\nnode 1\u0027s: Node 0: 000000000000000 Node 1: 11111\n\nThis wastes a little bit of mem_map space, but ends up being OK, and more\nfully utilizes the system\u0027s memory. memmap_init_zone() initializes all of the\n\"struct page\"s for node 0, even for the \"hole\", but those never get used,\nbecause there is no pfn_to_page() that resolves to those pages. However, only\ncalling pfn_to_page() once, memmap_init_zone() always uses the pages that were\nallocated for node0-\u003enode_mem_map because:\n\n\tstruct page *start \u003d pfn_to_page(start_pfn);\n\t// effectively start \u003d \u0026node-\u003enode_mem_map[0]\n\tfor (page \u003d start; page \u003c (start + size); page++) {\n\t\tinit_page_here();...\n\t\tpage++;\n\t}\n\nSlow, and wasteful, but generally harmless.\n\nBut, modify that to call pfn_to_page() for each loop iteration (like sparsemem\ndoes):\n\n\tfor (pfn \u003d start_pfn; pfn \u003c \u003c (start_pfn + size); pfn++++) {\n\t\tpage \u003d pfn_to_page(pfn);\n\t}\n\nAnd you end up trying to initialize node 1\u0027s pages too early, along with bogus\ndata from node 0.

This kind of\nmem_map[] is needed by discontiguous memory machines (like in the old\nCONFIG_DISCONTIGMEM case) as well as memory hotplug systems. Sparsemem\nreplaces DISCONTIGMEM when enabled, and it is hoped that it can eventually\nbecome a complete replacement.\n\nA significant advantage over DISCONTIGMEM is that it\u0027s completely separated\nfrom CONFIG_NUMA. When producing this patch, it became apparent in that NUMA\nand DISCONTIG are often confused.\n\nAnother advantage is that sparse doesn\u0027t require each NUMA node\u0027s ranges to be\ncontiguous. It can handle overlapping ranges between nodes with no problems,\nwhere DISCONTIGMEM currently throws away that memory.\n\nSparsemem uses an array to provide different pfn_to_page() translations for\neach SECTION_SIZE area of physical memory. This is what allows the mem_map[]\nto be chopped up.\n\nIn order to do quick pfn_to_page() operations, the section number of the page\nis encoded in page-\u003eflags. Part of the sparsemem infrastructure enables\nsharing of these bits more dynamically (at compile-time) between the\npage_zone() and sparsemem operations. However, on 32-bit architectures, the\nnumber of bits is quite limited, and may require growing the size of the\npage-\u003eflags type in certain conditions. Several things might force this to\noccur: a decrease in the SECTION_SIZE (if you want to hotplug smaller areas of\nmemory), an increase in the physical address space, or an increase in the\nnumber of used page-\u003eflags.\n\nOne thing to note is that, once sparsemem is present, the NUMA node\ninformation no longer needs to be stored in the page-\u003eflags.

But, if out of room, an alternate (theoretically slower) mechanism is\nused.\n\nThis patch introduces CONFIG_FLATMEM. It is used in almost all cases where\nthere used to be an #ifndef DISCONTIG, because SPARSEMEM and DISCONTIGMEM\noften have to compile out the same areas of code.\n\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nSigned-off-by: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nSigned-off-by: Martin Bligh \u003cmbligh@aracnet.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\nSigned-off-by: Bob Picco \u003cbob.picco@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b159d43fbf7eaaac6ecc647f51cf4257332db47b", "tree": "968d856c1bd80b47c76d27da272d95bcaf97aa78", "parents": [ "368a0a3afad08069b2679ecaff80fc18c10a6e2a" ], "author": { "name": "Andy Whitcroft", "email": "apw@shadowen.org", "time": "Thu Jun 23 00:07:52 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Thu Jun 23 09:45:04 2005 -0700" }, "message": "[PATCH] generify early_pfn_to_nid\n\nProvide a default implementation for early_pfn_to_nid returning node 0.

Details\nare as follows.\n\nCurrent state of module:\n\nA server using the current implementation (2.6.11.7) of the x25 module will\naccept a call request/ incoming call packet at the listening x.25 address,\nfrom all callers to that address, as long as NO call user data is present\nin the packet header.\n\nIf the server needs to choose to accept a particular call request/ incoming\ncall packet arriving at its listening x25 address, then the kernel has to\nallow a match of call user data present in the call request packet with its\nown. This is required when multiple servers listen at the same x25 address\nand device interface. The kernel currently matches ALL call user data, if\npresent.\n\nCurrent Changes:\n\nThis patch is a follow up to the patch submitted previously by Andrew\nHendry, and allows the user to selectively control the number of octets of\ncall user data in the call request packet, that the kernel will match. By\ndefault no call user data is matched, even if call user data is present. \nTo allow call user data matching, a cudmatchlength \u003e 0 has to be passed\ninto the kernel after which the passed number of octets will be matched. \nOtherwise the kernel behavior is exactly as the original implementation.\n\nThis patch also ensures that as is normally the case, no call user data\nwill be present in the Call accepted / call connected packet sent back to\nthe caller \n\nFuture Changes on next patch:\n\nThere are cases however when call user data may be present in the call\naccepted packet. According to the X.25 recommendation (ITU-T 10/96)\nsection 5.2.3.2 call user data may be present in the call accepted packet\nprovided the fast select facility is used. My next patch will include this\nfast select utility and the ability to send up to 128 octets call user data\nin the call accepted packet provided the fast select facility is used.

Centralizing this ownership in a core driver is desirable.\n\n- The IOC4 chip implements multiple functions (serial, IDE, others not\n yet implemented in the mainline kernel) but is not a multifunction\n PCI device. In order to properly handle device addition and removal\n as well as module insertion and deletion, an intermediary IOC4-specific\n driver layer is needed to handle these operations cleanly.\n\n- All IOC4 drivers are currently enabled by a single CONFIG value. As\n not all systems need all IOC4 functions, it is desireable to enable\n these drivers independently.\n\n- The current IOC4 core driver will trigger loading of all function-level\n drivers, as it makes direct calls to them. This situation should be\n reversed (i.e. function-level drivers cause loading of core driver)\n in order to maintain a clear and least-surprise driver loading model.\n\n- IOC4 hardware design necessitates some driver-level dependency on\n the PCI bus clock speed. Current code assumes a 66MHz bus, but the\n speed should be autodetected and appropriate compensation taken.\n\nThis patch series effects the above changes by a newly and better designed\nIOC4 core driver with which the function-level drivers can register and\nderegister themselves upon module insertion/removal. By tracking these\nmodules, device addition/removal is also handled properly. PCI resource\nmanagement and ownership issues are centralized in this core driver, and\nIOC4-wide configuration actions such as bus speed detection are also\nhandled in this core driver.\n\nThis patch:\n\nThe SGI IOC4 I/O controller chip implements multiple functions, though it is\nnot a multi-function PCI device. Additionally, various PCI resources of the\nIOC4 are shared by multiple hardware functions, and thus resource ownership by\ndriver is not clearly delineated. Due to the current driver design, all core\nand subordinate drivers must be loaded, or none, which is undesirable if not\nall IOC4 hardware features are being used.\n\nThis patch reorganizes the IOC4 drivers so that the core driver provides a\nsubdriver registration service. Through appropriate callbacks the subdrivers\ncan now handle device addition and removal, as well as module insertion and\ndeletion (though the IOC4 IDE driver requires further work before module\ndeletion will work). The core driver now takes care of allocating PCI\nresources and data which must be shared between subdrivers, to clearly\ndelineate module ownership of these items.\n\nSigned-off-by: Brent Casavant \u003cbcasavan@sgi.com\u003e\nAcked-by: Pat Gefre \u003cpfg@sgi.com\nAcked-by: Jeremy Higdon \u003cjeremy@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5b37b700f7c491a9320f4e29472bbaf23dded8fd", "tree": "e8a77c322bec5e75f0524c99f3be61645560b3c3", "parents": [ "da3caa204ca40c32dcb751ebead2a6835b83e8d1" ], "author": { "name": "Kumar Gala", "email": "galak@freescale.com", "time": "Tue Jun 21 17:15:18 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Tue Jun 21 18:46:23 2005 -0700" }, "message": "[PATCH] ppc32: Added support for new MPC8548 family of PowerQUICC III processors\n\nAdded descriptions of the new MPC8548 family processors, e500 core and\nperipherals.\n\nSigned-off-by: Kumar Gala \u003ckumar.gala@freescale.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "f14f75b81187cdbe10cc53a521bf9fdf97b59f8c", "tree": "5c0d48c8a3338e6f1747e6cd55f699be96ffef1a", "parents": [ "2caaad41e4aa8f5dd999695b4ddeaa0e7f3912a4" ], "author": { "name": "Jes Sorensen", "email": "jes@wildopensource.com", "time": "Tue Jun 21 17:15:02 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Tue Jun 21 18:46:18 2005 -0700" }, "message": "[PATCH] ia64 uncached alloc\n\nThis patch contains the ia64 uncached page allocator and the generic\nallocator (genalloc).

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": "e7c8d5c9955a4d2e88e36b640563f5d6d5aba48a", "tree": "f04f7b0d08cbc46d2f190a85904a3dd696dc6e88", "parents": [ "63551ae0feaaa23807ebea60de1901564bbef32e" ], "author": { "name": "Christoph Lameter", "email": "christoph@lameter.com", "time": "Tue Jun 21 17:14:47 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Tue Jun 21 18:46:16 2005 -0700" }, "message": "[PATCH] node local per-cpu-pages\n\nThis patch modifies the way pagesets in struct zone are managed.\n\nEach zone has a per-cpu array of pagesets.

This means that the operations to manage pages on remote zone can be\ndone with information available locally.\n\nWe play a macro trick so that non-NUMA pmachines avoid the additional\npointer chase on the page allocator fastpath.\n\nAIM7 benchmark on a 32 CPU SGI Altix\n\nw/o patches:\nTasks jobs/min jti jobs/min/task real cpu\n 1 484.68 100 484.6769 12.01 1.97 Fri Mar 25 11:01:42 2005\n 100 27140.46 89 271.4046 21.44 148.71 Fri Mar 25 11:02:04 2005\n 200 30792.02 82 153.9601 37.80 296.72 Fri Mar 25 11:02:42 2005\n 300 32209.27 81 107.3642 54.21 451.34 Fri Mar 25 11:03:37 2005\n 400 34962.83 78 87.4071 66.59 588.97 Fri Mar 25 11:04:44 2005\n 500 31676.92 75 63.3538 91.87 742.71 Fri Mar 25 11:06:16 2005\n 600 36032.69 73 60.0545 96.91 885.44 Fri Mar 25 11:07:54 2005\n 700 35540.43 77 50.7720 114.63 1024.28 Fri Mar 25 11:09:49 2005\n 800 33906.70 74 42.3834 137.32 1181.65 Fri Mar 25 11:12:06 2005\n 900 34120.67 73 37.9119 153.51 1325.26 Fri Mar 25 11:14:41 2005\n 1000 34802.37 74 34.8024 167.23 1465.26 Fri Mar 25 11:17:28 2005\n\nwith slab API changes and pageset patch:\n\nTasks jobs/min jti jobs/min/task real cpu\n 1 485.00 100 485.0000 12.00 1.96 Fri Mar 25 11:46:18 2005\n 100 28000.96 89 280.0096 20.79 150.45 Fri Mar 25 11:46:39 2005\n 200 32285.80 79 161.4290 36.05 293.37 Fri Mar 25 11:47:16 2005\n 300 40424.15 84 134.7472 43.19 438.42 Fri Mar 25 11:47:59 2005\n 400 39155.01 79 97.8875 59.46 590.05 Fri Mar 25 11:48:59 2005\n 500 37881.25 82 75.7625 76.82 730.19 Fri Mar 25 11:50:16 2005\n 600 39083.14 78 65.1386 89.35 872.79 Fri Mar 25 11:51:46 2005\n 700 38627.83 77 55.1826 105.47 1022.46 Fri Mar 25 11:53:32 2005\n 800 39631.94 78 49.5399 117.48 1169.94 Fri Mar 25 11:55:30 2005\n 900 36903.70 79 41.0041 141.94 1310.78 Fri Mar 25 11:57:53 2005\n 1000 36201.23 77 36.2012 160.77 1458.31 Fri Mar 25 12:00:34 2005\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Shobhit Dayal \u003cshobhit@calsoftinc.com\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": "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 goal of this\npatch is to reclaim some easily-freed pages from a zone before falling back\nonto another zone.\n\nOne of the major uses of this is NUMA machines. With the default allocator\nbehavior the allocator would look for memory in another zone, which might be\noff-node, before trying to reclaim from the current zone.\n\nThis adds a zone tuneable to enable early zone reclaim. It is selected on a\nper-zone basis and is turned on/off via syscall.\n\nAdding some extra throttling on the reclaim was also required (patch\n4/4). Without the machine would grind to a crawl when doing a \"make -j\"\nkernel build. Even with this patch the System Time is higher on\naverage, but it seems tolerable. Here are some numbers for kernbench\nruns on a 2-node, 4cpu, 8Gig RAM Altix in the \"make -j\" run:\n\n\t\t\twall user sys %cpu ctx sw. sleeps\n\t\t\t---- ---- --- ---- ------ ------\nNo patch\t\t1009 1384 847 258 298170 504402\nw/patch, no reclaim 880 1376 667 288 254064 396745\nw/patch \u0026 reclaim 1079 1385 926 252 291625 548873\n\nThese numbers are the average of 2 runs of 3 \"make -j\" runs done right\nafter system boot.
