But\neven the pte allocations still see a doubling of performance.\n\n1. Proven code from the IA64 arch.\n\n\tThe method used here has been fine tuned for years and\n\tis NUMA aware. It is based on the knowledge that accesses\n\tto page table pages are sparse in nature. Taking a page\n\toff the freelists instead of allocating a zeroed pages\n\tallows a reduction of number of cachelines touched\n\tin addition to getting rid of the slab overhead. So\n\tperformance improves. This is particularly useful if pgds\n\tcontain standard mappings. We can save on the teardown\n\tand setup of such a page if we have some on the quicklists.\n\tThis includes avoiding lists operations that are otherwise\n\tnecessary on alloc and free to track pgds.\n\n2. Light weight alternative to use slab to manage page size pages\n\n\tSlab overhead is significant and even page allocator use\n\tis pretty heavy weight. The use of a per cpu quicklist\n\tmeans that we touch only two cachelines for an allocation.\n\tThere is no need to access the page_struct (unless arch code\n\tneeds to fiddle around with it). So the fast past just\n\tmeans bringing in one cacheline at the beginning of the\n\tpage. That same cacheline may then be used to store the\n\tpage table entry. Or a second cacheline may be used\n\tif the page table entry is not in the first cacheline of\n\tthe page. The current code will zero the page which means\n\ttouching 32 cachelines (assuming 128 byte). We get down\n\tfrom 32 to 2 cachelines in the fast path.\n\n3. x86_64 gets lightweight page table page management.\n\n\tThis will allow x86_64 arch code to faster repopulate pgds\n\tand other page table entries. The list operations for pgds\n\tare reduced in the same way as for i386 to the point where\n\ta pgd is allocated from the page allocator and when it is\n\tfreed back to the page allocator. A pgd can pass through\n\tthe quicklists without having to be reinitialized.\n\n64 Consolidation of code from multiple arches\n\n\tSo far arches have their own implementation of quicklist\n\tmanagement. This patch moves that feature into the core allowing\n\tan easier maintenance and consistent management of quicklists.\n\nPage table pages have the characteristics that they are typically zero or in a\nknown state when they are freed. This is usually the exactly same state as\nneeded after allocation. So it makes sense to build a list of freed page\ntable pages and then consume the pages already in use first. Those pages have\nalready been initialized correctly (thus no need to zero them) and are likely\nalready cached in such a way that the MMU can use them most effectively. Page\ntable pages are used in a sparse way so zeroing them on allocation is not too\nuseful.\n\nSuch an implementation already exits for ia64. Howver, that implementation\ndid not support constructors and destructors as needed by i386 / x86_64. It\nalso only supported a single quicklist. The implementation here has\nconstructor and destructor support as well as the ability for an arch to\nspecify how many quicklists are needed.\n\nQuicklists are defined by an arch defining CONFIG_QUICKLIST. If more than one\nquicklist is necessary then we can define NR_QUICK for additional lists. F.e.\n i386 needs two and thus has\n\nconfig NR_QUICK\n\tint\n\tdefault 2\n\nIf an arch has requested quicklist support then pages can be allocated\nfrom the quicklist (or from the page allocator if the quicklist is\nempty) via:\n\nquicklist_alloc(\u003cquicklist-nr\u003e, \u003cgfpflags\u003e, \u003cconstructor\u003e)\n\nPage table pages can be freed using:\n\nquicklist_free(\u003cquicklist-nr\u003e, \u003cdestructor\u003e, \u003cpage\u003e)\n\nPages must have a definite state after allocation and before\nthey are freed. If no constructor is specified then pages\nwill be zeroed on allocation and must be zeroed before they are\nfreed.\n\nIf a constructor is used then the constructor will establish\na definite page state. F.e. the i386 and x86_64 pgd constructors\nestablish certain mappings.\n\nConstructors and destructors can also be used to track the pages.\ni386 and x86_64 use a list of pgds in order to be able to dynamically\nupdate standard mappings.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: \"David S.

It attempts to address a variety of concerns\nwith the existing implementation.\n\nA. Management of object queues\n\n A particular concern was the complex management of the numerous object\n queues in SLAB. SLUB has no such queues. Instead we dedicate a slab for\n each allocating CPU and use objects from a slab directly instead of\n queueing them up.\n\nB. Storage overhead of object queues\n\n SLAB Object queues exist per node, per CPU. The alien cache queue even\n has a queue array that contain a queue for each processor on each\n node. For very large systems the number of queues and the number of\n objects that may be caught in those queues grows exponentially. On our\n systems with 1k nodes / processors we have several gigabytes just tied up\n for storing references to objects for those queues This does not include\n the objects that could be on those queues. One fears that the whole\n memory of the machine could one day be consumed by those queues.\n\nC. SLAB meta data overhead\n\n SLAB has overhead at the beginning of each slab. This means that data\n cannot be naturally aligned at the beginning of a slab block. SLUB keeps\n all meta data in the corresponding page_struct. Objects can be naturally\n aligned in the slab. F.e. a 128 byte object will be aligned at 128 byte\n boundaries and can fit tightly into a 4k page with no bytes left over.\n SLAB cannot do this.\n\nD. SLAB has a complex cache reaper\n\n SLUB does not need a cache reaper for UP systems. On SMP systems\n the per CPU slab may be pushed back into partial list but that\n operation is simple and does not require an iteration over a list\n of objects. SLAB expires per CPU, shared and alien object queues\n during cache reaping which may cause strange hold offs.\n\nE. SLAB has complex NUMA policy layer support\n\n SLUB pushes NUMA policy handling into the page allocator. This means that\n allocation is coarser (SLUB does interleave on a page level) but that\n situation was also present before 2.6.13. SLABs application of\n policies to individual slab objects allocated in SLAB is\n certainly a performance concern due to the frequent references to\n memory policies which may lead a sequence of objects to come from\n one node after another. SLUB will get a slab full of objects\n from one node and then will switch to the next.\n\nF. Reduction of the size of partial slab lists\n\n SLAB has per node partial lists. This means that over time a large\n number of partial slabs may accumulate on those lists. These can\n only be reused if allocator occur on specific nodes. SLUB has a global\n pool of partial slabs and will consume slabs from that pool to\n decrease fragmentation.\n\nG. Tunables\n\n SLAB has sophisticated tuning abilities for each slab cache. One can\n manipulate the queue sizes in detail. However, filling the queues still\n requires the uses of the spin lock to check out slabs. SLUB has a global\n parameter (min_slab_order) for tuning. Increasing the minimum slab\n order can decrease the locking overhead. The bigger the slab order the\n less motions of pages between per CPU and partial lists occur and the\n better SLUB will be scaling.\n\nG. Slab merging\n\n We often have slab caches with similar parameters. SLUB detects those\n on boot up and merges them into the corresponding general caches. This\n leads to more effective memory use. About 50% of all caches can\n be eliminated through slab merging. This will also decrease\n slab fragmentation because partial allocated slabs can be filled\n up again. Slab merging can be switched off by specifying\n slub_nomerge on boot up.\n\n Note that merging can expose heretofore unknown bugs in the kernel\n because corrupted objects may now be placed differently and corrupt\n differing neighboring objects. Enable sanity checks to find those.\n\nH. Diagnostics\n\n The current slab diagnostics are difficult to use and require a\n recompilation of the kernel. SLUB contains debugging code that\n is always available (but is kept out of the hot code paths).\n SLUB diagnostics can be enabled via the \"slab_debug\" option.\n Parameters can be specified to select a single or a group of\n slab caches for diagnostics. This means that the system is running\n with the usual performance and it is much more likely that\n race conditions can be reproduced.\n\nI. Resiliency\n\n If basic sanity checks are on then SLUB is capable of detecting\n common error conditions and recover as best as possible to allow the\n system to continue.\n\nJ. Tracing\n\n Tracing can be enabled via the slab_debug\u003dT,\u003cslabcache\u003e option\n during boot. SLUB will then protocol all actions on that slabcache\n and dump the object contents on free.\n\nK. On demand DMA cache creation.\n\n Generally DMA caches are not needed. If a kmalloc is used with\n __GFP_DMA then just create this single slabcache that is needed.\n For systems that have no ZONE_DMA requirement the support is\n completely eliminated.\n\nL. Performance increase\n\n Some benchmarks have shown speed improvements on kernbench in the\n range of 5-10%. The locking overhead of slub is based on the\n underlying base allocation size. If we can reliably allocate\n larger order pages then it is possible to increase slub\n performance much further. The anti-fragmentation patches may\n enable further performance increases.\n\nTested on:\ni386 UP + SMP, x86_64 UP + SMP + NUMA emulation, IA64 NUMA + Simulator\n\nSLUB Boot options\n\nslub_nomerge\t\tDisable merging of slabs\nslub_min_order\u003dx\tRequire a minimum order for slab caches.

If this flag is set when the serial port is configured, any\nattempts to alter the port\u0027s type, io address, irq or base clock with\nsetserial are ignored.\n\nIn addition this patch uses the new flag for on-chip serial ports probed in\narch/powerpc/kernel/legacy_serial.c, and for other hard-wired serial ports\nprobed by drivers/serial/of_serial.c.\n\nSigned-off-by: David Gibson \u003cdwg@au1.ibm.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "bd71c182d5a02337305fc381831c11029dd17d64", "tree": "0b21234a7d1c38bfcafc12b6dcbfb3455d73b587", "parents": [ "beab697ab4b2962e3d741b476abe443baad0933d" ], "author": { "name": "Thomas Koeller", "email": "thomas.koeller@baslerweb.com", "time": "Sun May 06 14:48:47 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon May 07 12:12:50 2007 -0700" }, "message": "RM9000 serial driver\n\nAdd support for the integrated serial ports of the MIPS RM9122 processor\nand its relatives.\n\nThe patch also does some whitespace cleanup.\n\n[akpm@linux-foundation.org: cleanups]\nSigned-off-by: Thomas Koeller \u003cthomas.koeller@baslerweb.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "beab697ab4b2962e3d741b476abe443baad0933d", "tree": "f581ce38378f6cacbf0042b4eb9c084a6fc932d9", "parents": [ "6179b5562d5d17c7c09b54cb11dd925ca308d7a9" ], "author": { "name": "Marc St-Jean", "email": "stjeanma@pmc-sierra.com", "time": "Sun May 06 14:48:45 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon May 07 12:12:50 2007 -0700" }, "message": "serial driver PMC MSP71xx\n\nSerial driver patch for the PMC-Sierra MSP71xx devices.\n\nThere are three different fixes:\n\n1 Fix for DesignWare APB THRE errata: In brief, this is a non-standard\n 16550 in that the THRE interrupt will not re-assert itself simply by\n disabling and re-enabling the THRI bit in the IER, it is only re-enabled\n if a character is actually sent out.\n\n It appears that the \"8250-uart-backup-timer.patch\" in the \"mm\" tree\n also fixes it so we have dropped our initial workaround. This patch now\n needs to be applied on top of that \"mm\" patch.\n\n2 Fix for Busy Detect on LCR write: The DesignWare APB UART has a feature\n which causes a new Busy Detect interrupt to be generated if it\u0027s busy\n when the LCR is written. This fix saves the value of the LCR and\n rewrites it after clearing the interrupt.\n\n3 Workaround for interrupt/data concurrency issue: The SoC needs to\n ensure that writes that can cause interrupts to be cleared reach the UART\n before returning from the ISR. This fix reads a non-destructive register\n on the UART so the read transaction completion ensures the previously\n queued write transaction has also completed.\n\nSigned-off-by: Marc St-Jean \u003cMarc_St-Jean@pmc-sierra.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6179b5562d5d17c7c09b54cb11dd925ca308d7a9", "tree": "2f740d0f653678557a5601c6dffed1287b9aa513", "parents": [ "02c83595b86480ee4d61665beb13f76685d40239" ], "author": { "name": "Bernhard Walle", "email": "bwalle@suse.de", "time": "Sun May 06 14:48:44 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon May 07 12:12:50 2007 -0700" }, "message": "add new_id to PCMCIA drivers\n\nPCI drivers have the new_id file in sysfs which allows new IDs to be added\nat runtime.

In\nother words, this means that the following race is possible:\n\n\twhile (CQ is not empty)\n\t\tib_poll_cq(CQ);\n\t// new completion is added after while loop is exited\n\tib_req_notify_cq(CQ);\n\t// no event is generated for the existing completion\n\nTo close this race, the IB spec recommends doing another poll of the\nCQ after requesting notification.\n\nHowever, it is not always possible to arrange code this way (for\nexample, we have found that NAPI for IPoIB cannot poll after\nrequesting notification). Also, some hardware (eg Mellanox HCAs)\nactually will generate an event for completions added before the call\nto ib_req_notify_cq() -- which is allowed by the spec, since there\u0027s\nno way for any upper-layer consumer to know exactly when a completion\nwas really added -- so the extra poll of the CQ is just a waste.\n\nMotivated by this, we add a new flag \"IB_CQ_REPORT_MISSED_EVENTS\" for\nib_req_notify_cq() so that it can return a hint about whether the a\ncompletion may have been added before the request for notification.\nThe return value of ib_req_notify_cq() is extended so:\n\n\t \u003c 0\tmeans an error occurred while requesting notification\n\t\u003d\u003d 0\tmeans notification was requested successfully, and if\n\t\tIB_CQ_REPORT_MISSED_EVENTS was passed in, then no\n\t\tevents were missed and it is safe to wait for another\n\t\tevent.\n\t \u003e 0\tis only returned if IB_CQ_REPORT_MISSED_EVENTS was\n\t\tpassed in.
