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.

A pointer to another data structure may be stored in the private\nfield such as struct mem_size_stats, which acts as the smaps accumulator. For\neach pmd in the VMA, the action function is called with a pointer to its\nstruct vm_area_struct, a pointer to the pmd_t, its start and end addresses,\nand the private field.\n\nThe interface for walking pmd\u0027s in a VMA for fs/proc/task_mmu.c is now:\n\n\tvoid for_each_pmd(struct vm_area_struct *vma,\n\t\t\t void (*action)(struct vm_area_struct *vma,\n\t\t\t\t\t pmd_t *pmd, unsigned long addr,\n\t\t\t\t\t unsigned long end,\n\t\t\t\t\t void *private),\n\t\t\t void *private);\n\nSince the pmd walker is now extracted from the smaps code, smaps_one_pmd() is\ninvoked for each pmd in the VMA. Its behavior and efficiency is identical to\nthe existing implementation.\n\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0013572b2ae535bfd6314f22d9aef53725ea00d8", "tree": "0c405dfe8a106099696ed9955b4405e6d7caed70", "parents": [ "10a8d6ae4b3182d6588a5809a8366343bc295c20" ], "author": { "name": "Zachary Amsden", "email": "zach@vmware.com", "time": "Sun May 06 14:49:20 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Mon May 07 12:12:52 2007 -0700" }, "message": "i386: use pte_update_defer in ptep_test_and_clear_{dirty,young}\n\nIf you actually clear the bit, you need to:\n\n+ pte_update_defer(vma-\u003evm_mm, addr, ptep);\n\nThe reason is, when updating PTEs, the hypervisor must be notified.

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.
