If we find the destination page is non uptodate, unlock it (this could be\n made slightly more optimal), then allocate a temporary page to copy the\n source data into. Relock the destination page and continue with the copy.\n However, instead of a usercopy (which might take a fault), copy the data\n from the pinned temporary page via the kernel address space.\n\n(also, rename maxlen to seglen, because it was confusing)\n\nThis increases the CPU/memory copy cost by almost 50% on the affected\nworkloads. That will be solved by introducing a new set of pagecache write\naops in a subsequent patch.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4a9e5ef1f4f15205e477817a5cefc34bd3f65f55", "tree": "51f52086ecbccc3f41955d8d12293ef7a566a05b", "parents": [ "eb2be189317d031895b5ca534fbf735eb546158b" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Tue Oct 16 01:24:58 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:42:54 2007 -0700" }, "message": "mm: write iovec cleanup\n\nHide some of the open-coded nr_segs tests into the iovec helpers.

These writes to\n the struct page could cause excessive cacheline bouncing on big\n systems. There are a number of ways this could be addressed if it is\n an issue.\n\nAnd indeed this cacheline bouncing has shown up on large SGI systems.\nThere was a situation where an Altix system was essentially livelocked\ntearing down ZERO_PAGE pagetables when an HPC app aborted during startup.\nThis situation can be avoided in userspace, but it does highlight the\npotential scalability problem with refcounting ZERO_PAGE, and corner\ncases where it can really hurt (we don\u0027t want the system to livelock!).\n\nThere are several broad ways to fix this problem:\n1. add back some special casing to avoid refcounting ZERO_PAGE\n2. per-node or per-cpu ZERO_PAGES\n3. remove the ZERO_PAGE completely\n\nI will argue for 3. The others should also fix the problem, but they\nresult in more complex code than does 3, with little or no real benefit\nthat I can see.\n\nWhy? Inserting a ZERO_PAGE for anonymous read faults appears to be a\nfalse optimisation: if an application is performance critical, it would\nnot be doing many read faults of new memory, or at least it could be\nexpected to write to that memory soon afterwards. If cache or memory use\nis critical, it should not be working with a significant number of\nZERO_PAGEs anyway (a more compact representation of zeroes should be\nused).\n\nAs a sanity check -- mesuring on my desktop system, there are never many\nmappings to the ZERO_PAGE (eg. 2 or 3), thus memory usage here should not\nincrease much without it.\n\nWhen running a make -j4 kernel compile on my dual core system, there are\nabout 1,000 mappings to the ZERO_PAGE created per second, but about 1,000\nZERO_PAGE COW faults per second (less than 1 ZERO_PAGE mapping per second\nis torn down without being COWed). So removing ZERO_PAGE will save 1,000\npage faults per second when running kbuild, while keeping it only saves\nless than 1 page clearing operation per second. 1 page clear is cheaper\nthan a thousand faults, presumably, so there isn\u0027t an obvious loss.\n\nNeither the logical argument nor these basic tests give a guarantee of no\nregressions. However, this is a reasonable opportunity to try to remove\nthe ZERO_PAGE from the pagefault path. If it is found to cause regressions,\nwe can reintroduce it and just avoid refcounting it.\n\nThe /dev/zero ZERO_PAGE usage and TLB tricks also get nuked. I don\u0027t see\nmuch use to them except on benchmarks. All other users of ZERO_PAGE are\nconverted just to use ZERO_PAGE(0) for simplicity. We can look at\nreplacing them all and maybe ripping out ZERO_PAGE completely when we are\nmore satisfied with this solution.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus \"snif\" Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "aadb4bc4a1f9108c1d0fbd121827c936c2ed4217", "tree": "879b7c9ba11a65958e4477c563602e08d9e6635f", "parents": [ "57f6b96c09c30e444e0d3fc3080feba037657a7b" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Tue Oct 16 01:24:38 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:42:53 2007 -0700" }, "message": "SLUB: direct pass through of page size or higher kmalloc requests\n\nThis gets rid of all kmalloc caches larger than page size.

This works both inline where we will call __get_free_pages\ninstead of kmem_cache_alloc and in __kmalloc.\n\nkfree is modified to check if the object is in a slab page.

Roughly similar to what\nSLOB does.\n\nAdvantages:\n- Reduces memory overhead for kmalloc array\n- Large kmalloc operations are faster since they do not\n need to pass through the slab allocator to get to the\n page allocator.\n- Performance increase of 10%-20% on alloc and 50% on free for\n PAGE_SIZEd allocations.\n SLUB must call page allocator for each alloc anyways since\n the higher order pages which that allowed avoiding the page alloc calls\n are not available in a reliable way anymore.

It would be great if it could be the default so that we can get\nrid of various forms of DISCONTIG and other variations on memory maps. So far\nwhat has hindered this are the additional lookups that SPARSEMEM introduces\nfor virt_to_page and page_address. This goes so far that the code to do this\nhas to be kept in a separate function and cannot be used inline.\n\nThis patch introduces a virtual memmap mode for SPARSEMEM, in which the memmap\nis mapped into a virtually contigious area, only the active sections are\nphysically backed. This allows virt_to_page page_address and cohorts become\nsimple shift/add operations. No page flag fields, no table lookups, nothing\ninvolving memory is required.\n\nThe two key operations pfn_to_page and page_to_page become:\n\n #define __pfn_to_page(pfn) (vmemmap + (pfn))\n #define __page_to_pfn(page) ((page) - vmemmap)\n\nBy having a virtual mapping for the memmap we allow simple access without\nwasting physical memory. As kernel memory is typically already mapped 1:1\nthis introduces no additional overhead. The virtual mapping must be big\nenough to allow a struct page to be allocated and mapped for all valid\nphysical pages. This vill make a virtual memmap difficult to use on 32 bit\nplatforms that support 36 address bits.\n\nHowever, if there is enough virtual space available and the arch already maps\nits 1-1 kernel space using TLBs (f.e. true of IA64 and x86_64) then this\ntechnique makes SPARSEMEM lookups even more efficient than CONFIG_FLATMEM.\nFLATMEM needs to read the contents of the mem_map variable to get the start of\nthe memmap and then add the offset to the required entry. vmemmap is a\nconstant to which we can simply add the offset.\n\nThis patch has the potential to allow us to make SPARSMEM the default (and\neven the only) option for most systems. It should be optimal on UP, SMP and\nNUMA on most platforms.

It would be great if it could be the default so that we can get\nrid of various forms of DISCONTIG and other variations on memory maps. So far\nwhat has hindered this are the additional lookups that SPARSEMEM introduces\nfor virt_to_page and page_address. This goes so far that the code to do this\nhas to be kept in a separate function and cannot be used inline.\n\nThis patch introduces a virtual memmap mode for SPARSEMEM, in which the memmap\nis mapped into a virtually contigious area, only the active sections are\nphysically backed. This allows virt_to_page page_address and cohorts become\nsimple shift/add operations. No page flag fields, no table lookups, nothing\ninvolving memory is required.\n\nThe two key operations pfn_to_page and page_to_page become:\n\n #define __pfn_to_page(pfn) (vmemmap + (pfn))\n #define __page_to_pfn(page) ((page) - vmemmap)\n\nBy having a virtual mapping for the memmap we allow simple access without\nwasting physical memory. As kernel memory is typically already mapped 1:1\nthis introduces no additional overhead. The virtual mapping must be big\nenough to allow a struct page to be allocated and mapped for all valid\nphysical pages. This vill make a virtual memmap difficult to use on 32 bit\nplatforms that support 36 address bits.\n\nHowever, if there is enough virtual space available and the arch already maps\nits 1-1 kernel space using TLBs (f.e. true of IA64 and x86_64) then this\ntechnique makes SPARSEMEM lookups even more efficient than CONFIG_FLATMEM.\nFLATMEM needs to read the contents of the mem_map variable to get the start of\nthe memmap and then add the offset to the required entry. vmemmap is a\nconstant to which we can simply add the offset.\n\nThis patch has the potential to allow us to make SPARSMEM the default (and\neven the only) option for most systems. It should be optimal on UP, SMP and\nNUMA on most platforms. Then we may even be able to remove the other memory\nmodels: FLATMEM, DISCONTIG etc.\n\nThe current aim is to bring a common virtually mapped mem_map to all\narchitectures. This should facilitate the removal of the bespoke\nimplementations from the architectures. This also brings performance\nimprovements for most architecture making sparsmem vmemmap the more desirable\nmemory model. The ultimate aim of this work is to expand sparsemem support to\nencompass all the features of the other memory models. This could allow us to\ndrop support for and remove the other models in the longer term.\n\nBelow are some comparitive kernbench numbers for various architectures,\ncomparing default memory model against SPARSEMEM VMEMMAP. All but ia64 show\nmarginal improvement; we expect the ia64 figures to be sorted out when the\nlarger mapping support returns.\n\nx86-64 non-NUMA\n Base VMEMAP % change (-ve good)\nUser 85.07 84.84 -0.26\nSystem 34.32 33.84 -1.39\nTotal 119.38 118.68 -0.59\n\nia64\n Base VMEMAP % change (-ve good)\nUser 1016.41 1016.93 0.05\nSystem 50.83 51.02 0.36\nTotal 1067.25 1067.95 0.07\n\nx86-64 NUMA\n Base VMEMAP % change (-ve good)\nUser 30.77 431.73 0.22\nSystem 45.39 43.98 -3.11\nTotal 476.17 475.71 -0.10\n\nppc64\n Base VMEMAP % change (-ve good)\nUser 488.77 488.35 -0.09\nSystem 56.92 56.37 -0.97\nTotal 545.69 544.72 -0.18\n\nBelow are some AIM bencharks on IA64 and x86-64 (thank Bob).

If you are actually capable of\nwaking up the system from that port, would be nice to test that as well.\n\nSigned-off-by: Guennadi Liakhovetski \u003cg.liakhovetski@gmx.de\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "aa5346a2126ea65e8ef04eebea0f2481f701bdb8", "tree": "a7d59e9cc61482d379baa676f9455c29529fa849", "parents": [ "bf0df636e5ddf43cbacff8435962ee8aa40f563e" ], "author": { "name": "Guennadi Liakhovetski", "email": "g.liakhovetski@gmx.de", "time": "Tue Oct 16 01:24:01 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:42:50 2007 -0700" }, "message": "provide stubs for enable_irq_wake() and disable_irq_wake()\n\nProvide {enable,disable}_irq_wakeup dummies for undefined\ncross-compilers for platforms without CONFIG_GENERIC_IRQ.\n\nNeeded by wake-up-from-a-serial-port.patch\n\nSigned-off-by: Guennadi Liakhovetski \u003cg.liakhovetski@gmx.de\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "bf0df636e5ddf43cbacff8435962ee8aa40f563e", "tree": "5bbf1cc53eed746e96ebc03017da1986de120a16", "parents": [ "7201863ca7a97e83daea1ea2755750a256245600" ], "author": { "name": "Alan Cox", "email": "alan@lxorguk.ukuu.org.uk", "time": "Tue Oct 16 01:24:00 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Oct 16 09:42:50 2007 -0700" }, "message": "8250_pci: Autodetect mainpine cards\n\nAdd support for a whole range of boards.
