Presently this requires\na global kernel TLB flush, which on most architectures is a broadcast IPI\nto all CPUs to flush the cache. This is all done under a global lock. As\nthe number of CPUs increases, so will the number of vunmaps a scaled\nworkload will want to perform, and so will the cost of a global TLB flush.\n This gives terrible quadratic scalability characteristics.\n\nAnother problem is that the entire vmap subsystem works under a single\nlock. It is a rwlock, but it is actually taken for write in all the fast\npaths, and the read locking would likely never be run concurrently anyway,\nso it\u0027s just pointless.\n\nThis is a rewrite of vmap subsystem to solve those problems. The existing\nvmalloc API is implemented on top of the rewritten subsystem.\n\nThe TLB flushing problem is solved by using lazy TLB unmapping. vmap\naddresses do not have to be flushed immediately when they are vunmapped,\nbecause the kernel will not reuse them again (would be a use-after-free)\nuntil they are reallocated. So the addresses aren\u0027t allocated again until\na subsequent TLB flush. A single TLB flush then can flush multiple\nvunmaps from each CPU.\n\nXEN and PAT and such do not like deferred TLB flushing because they can\u0027t\nalways handle multiple aliasing virtual addresses to a physical address.\nThey now call vm_unmap_aliases() in order to flush any deferred mappings.\nThat call is very expensive (well, actually not a lot more expensive than\na single vunmap under the old scheme), however it should be OK if not\ncalled too often.\n\nThe virtual memory extent information is stored in an rbtree rather than a\nlinked list to improve the algorithmic scalability.\n\nThere is a per-CPU allocator for small vmaps, which amortizes or avoids\nglobal locking.\n\nTo use the per-CPU interface, the vm_map_ram / vm_unmap_ram interfaces\nmust be used in place of vmap and vunmap. Vmalloc does not use these\ninterfaces at the moment, so it will not be quite so scalable (although it\nwill use lazy TLB flushing).\n\nAs a quick test of performance, I ran a test that loops in the kernel,\nlinearly mapping then touching then unmapping 4 pages. Different numbers\nof tests were run in parallel on an 4 core, 2 socket opteron. Results are\nin nanoseconds per map+touch+unmap.\n\nthreads vanilla vmap rewrite\n1 14700 2900\n2 33600 3000\n4 49500 2800\n8 70631 2900\n\nSo with a 8 cores, the rewritten version is already 25x faster.\n\nIn a slightly more realistic test (although with an older and less\nscalable version of the patch), I ripped the not-very-good vunmap batching\ncode out of XFS, and implemented the large buffer mapping with vm_map_ram\nand vm_unmap_ram... along with a couple of other tricks, I was able to\nspeed up a large directory workload by 20x on a 64 CPU system.

One problem spot are\nkernel timers, where the detection of the problem often happens in interrupt\ncontext and usually causes the machine to panic.\n\nWhile working on a timer related bug report I had to hack specialized code\ninto the timer subsystem to get a reasonable hint for the root cause. This\ndebug hack was fine for temporary use, but far from a mergeable solution due\nto the intrusiveness into the timer code.\n\nThe code further lacked the ability to detect and report the root cause\ninstantly and keep the system operational.\n\nKeeping the system operational is important to get hold of the debug\ninformation without special debugging aids like serial consoles and special\nknowledge of the bug reporter.\n\nThe problems described above are not restricted to timers, but timers tend to\nexpose it usually in a full system crash. Other objects are less explosive,\nbut the symptoms caused by such mistakes can be even harder to debug.\n\nInstead of creating specialized debugging code for the timer subsystem a\ngeneric infrastructure is created which allows developers to verify their code\nand provides an easy to enable debug facility for users in case of trouble.\n\nThe debugobjects core code keeps track of operations on static and dynamic\nobjects by inserting them into a hashed list and sanity checking them on\nobject operations and provides additional checks whenever kernel memory is\nfreed.\n\nThe tracked object operations are:\n- initializing an object\n- adding an object to a subsystem list\n- deleting an object from a subsystem list\n\nEach operation is sanity checked before the operation is executed and the\nsubsystem specific code can provide a fixup function which allows to prevent\nthe damage of the operation. When the sanity check triggers a warning message\nand a stack trace is printed.\n\nThe list of operations can be extended if the need arises. For now it\u0027s\nlimited to the requirements of the first user (timers).\n\nThe core code enqueues the objects into hash buckets. The hash index is\ngenerated from the address of the object to simplify the lookup for the check\non kfree/vfree.

These all need the basic abstraction of being\nable to group together multiple processes in an aggregate, in order to\ntrack/limit the resources permitted to those processes, or control\nother behaviour of the processes, and all implement this grouping in\ndifferent ways.\n\nThis patchset provides a framework for tracking and grouping processes\ninto arbitrary \"cgroups\" and assigning arbitrary state to those\ngroupings, in order to control the behaviour of the cgroup as an\naggregate.\n\nThe intention is that the various resource management and\nvirtualization/cgroup efforts can also become task cgroup\nclients, with the result that:\n\n- the userspace APIs are (somewhat) normalised\n\n- it\u0027s easier to test e.g. the ResGroups CPU controller in\n conjunction with the BeanCounters memory controller, or use either of\nthem as the resource-control portion of a virtual server system.\n\n- the additional kernel footprint of any of the competing resource\n management systems is substantially reduced, since it doesn\u0027t need\n to provide process grouping/containment, hence improving their\n chances of getting into the kernel\n\nThis patch:\n\nAdd the main task cgroups framework - the cgroup filesystem, and the\nbasic structures for tracking membership and associating subsystem state\nobjects to tasks.\n\nSigned-off-by: Paul Menage \u003cmenage@google.com\u003e\nCc: Serge E.

If it is set to the maximum possible then we only waste\nsome memory for early boot users.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "15700770ef7c5d12e2f1659d2ddbeb3f658d9f37", "tree": "7fa2f81c33c9efcb1a1568385beead75c5892cfb", "parents": [ "6de410c2b0cc055ae9ee640c84331f6a70878d9b", "11de39e2fbbc592018e0a231d0ee773653dcc8d6" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Sun May 06 13:21:57 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Sun May 06 13:21:57 2007 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/sam/kbuild: (38 commits)\n kconfig: fix mconf segmentation fault\n kbuild: enable use of code from a different dir\n kconfig: error out if recursive dependencies are found\n kbuild: scripts/basic/fixdep segfault on pathological string-o-death\n kconfig: correct minor typo in Kconfig warning message.\n kconfig: fix path to modules.txt in Kconfig help\n usr/Kconfig: fix typo\n kernel-doc: alphabetically-sorted entries in index.html of \u0027htmldocs\u0027\n kbuild: be more explicit on missing .config file\n kbuild: clarify the creation of the LOCALVERSION_AUTO string.\n kbuild: propagate errors from find in scripts/gen_initramfs_list.sh\n kconfig: refer to qt3 if we cannot find qt libraries\n kbuild: handle compressed cpio initramfs-es\n kbuild: ignore section mismatch warning for references from .paravirtprobe to .init.text\n kbuild: remove stale comment in modpost.c\n kbuild/mkuboot.sh: allow spaces in CROSS_COMPILE\n kbuild: fix make mrproper for Documentation/DocBook/man\n kbuild: remove kconfig binaries during make mrproper\n kconfig/menuconfig: do not hardcode \u0027.config\u0027\n kbuild: override build timestamp \u0026 version\n ...\n" }, { "commit": "aae5f662a32c35b1a962627535acb588d48ff5f9", "tree": "6e300ed8557e850e350c95dffb57ff9d5d5b182d", "parents": [ "85bd2fddd68e757da8e1af98f857f61a3c9ce647" ], "author": { "name": "Sam Ravnborg", "email": "sam@ravnborg.org", "time": "Mon Feb 26 16:45:41 2007 +0100" }, "committer": { "name": "Sam Ravnborg", "email": "sam@ravnborg.org", "time": "Wed May 02 20:58:07 2007 +0200" }, "message": "kbuild: whitelist section mismatch in init/main.c\n\nIn init/main.c we have a reference from rest_init() to .init.text\nwhich is intentional.\nRename the function \u0027init\u0027 to \u0027kernel_init\u0027 to make it a\nkernel wide unique symbol and whitelist the reference.\n\nSigned-off-by: Sam Ravnborg \u003csam@ravnborg.org\u003e\n" }, { "commit": "b6e3590f8145c77b8fcef3247e2412335221412f", "tree": "47fb1a28e41fd9f4e1aef45b5482b69b8d7c154e", "parents": [ "de90c5ce832b1218042316260ff9268b00fdcba3" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy@goop.org", "time": "Wed May 02 19:27:12 2007 +0200" }, "committer": { "name": "Andi Kleen", "email": "andi@basil.nowhere.org", "time": "Wed May 02 19:27:12 2007 +0200" }, "message": "[PATCH] x86: Allow percpu variables to be page-aligned\n\nLet\u0027s allow page-alignment in general for per-cpu data (wanted by Xen, and\nIngo suggested KVM as well).\n\nBecause larger alignments can use more room, we increase the max per-cpu\nmemory to 64k rather than 32k: it\u0027s getting a little tight.\n\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n" }, { "commit": "53b8a315b76a3f3c70a5644976c0095460eb13d8", "tree": "f407a607adb1f552942aef9150ec709ed3f01798", "parents": [ "74c7aa8b8581e0ba8d6d17c623b9279aaabbb0cf" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Tue Feb 20 13:57:51 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 20 17:10:13 2007 -0800" }, "message": "[PATCH] Convert highest_possible_processor_id to nr_cpu_ids\n\nWe frequently need the maximum number of possible processors in order to\nallocate arrays for all processors.

Most architectures stores two copies of this buffer,\none for future reference and one for parameter parsing.\n\nCurrent kernel command-line size for most architecture is much too small for\nmodule parameters, video settings, initramfs paramters and much more. The\nproblem is that setting COMMAND_LINE_SIZE to a grater value, allocates static\nbuffers.\n\nIn order to allow a greater command-line size, these buffers should be\ndynamically allocated or marked as init disposable buffers, so unused memory\ncan be released.\n\nThis patch renames the static saved_command_line variable into\nboot_command_line adding __initdata attribute, so that it can be disposed\nafter initialization.
