This\nis a slightly fragile thing right now, needing both an address and a\nsize, and many driver writers do.. various things there.\n\nThis patch introduces an pci_ioremap() function taking just a PCI device\nstruct and the bar number as arguments, and figures this all out itself,\nin one place. In addition, we can add various sanity checks to this\nfunction (the patch already checks to make sure that the bar in question\nreally is a MEM bar; few to no drivers do that sort of thing).\n\nHopefully with this type of API we get less chance of mistakes in\ndrivers with ioremap() operations.\n\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "58c3a727cb73b75a9104d295f096cca12959a5a5", "tree": "70f1fe31f1ec12021777b6c6c49167356a864749", "parents": [ "201de56eb22f1ff3f36804bc70cbff220b50f067" ], "author": { "name": "Yu Zhao", "email": "yu.zhao@intel.com", "time": "Tue Oct 14 14:02:53 2008 +0800" }, "committer": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Mon Oct 20 10:54:32 2008 -0700" }, "message": "PCI: support PCIe ARI capability\n\nThis patch adds support for PCI Express Alternative Routing-ID\nInterpretation (ARI) capability.\n\nThe ARI capability extends the Function Number field of the PCI Express\nEndpoint by reusing the Device Number which is otherwise hardwired to 0.\nWith ARI, an Endpoint can have up to 256 functions.\n\nSigned-off-by: Yu Zhao \u003cyu.zhao@intel.com\u003e\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "c322b28a04c084a467a862766f74c40c917a721c", "tree": "74845fc3bd358be76291e4aefa60ea2adf86aa32", "parents": [ "5d9bc1fa47f0c1561f1d7c0bdff5e24860852b42" ], "author": { "name": "Zhao, Yu", "email": "yu.zhao@intel.com", "time": "Mon Oct 13 19:36:05 2008 +0800" }, "committer": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Mon Oct 20 10:54:28 2008 -0700" }, "message": "PCI: use same arg names in PCI_VDEVICE comment\n\nThis cleanup makes the argument names in PCI_VDEVICE comment consistent\nwith those used in its definition.\n\nSigned-off-by: Yu Zhao \u003cyu.zhao@intel.com\u003e\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "37a84ec668ba251ae02cf2c2c664baf6b247ae1f", "tree": "1cc937e4264fade2d790757b1f294d6e33479d2d", "parents": [ "f7a10e32a1a7ae240fa3925c5727d224eba3e31d" ], "author": { "name": "Seth Heasley", "email": "seth.heasley@intel.com", "time": "Thu Aug 28 15:40:59 2008 -0700" }, "committer": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Mon Oct 20 10:53:48 2008 -0700" }, "message": "x86/PCI: irq and pci_ids patch for Intel Ibex Peak DeviceIDs\n\nThis patch updates the Intel Ibex Peak (PCH) LPC and SMBus Controller\nDeviceIDs.\n\nThe LPC Controller ID is set by Firmware within the range of\n0x3b00-3b1f.

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.

We can defer the moving of\n nonreclaimable pages until when vmscan [shrink_*_list()]\n encounters them. Vmscan will only need to handle such pages\n once, but if there are a lot of them it could impact system\n performance.\n\n2) The \u0027vma\u0027 argument to page_evictable() is require to notice that\n we\u0027re faulting a page into an mlock()ed vma w/o having to scan the\n page\u0027s rmap in the fault path. Culling mlock()ed anon pages is\n currently the only reason for this patch.\n\n3) We can\u0027t cull swap pages in read_swap_cache_async() because the\n vma argument doesn\u0027t necessarily correspond to the swap cache\n offset passed in by swapin_readahead().

This\n effectively replaces the use of one of the lru list links\n as an mlock count. If this mechanism let\u0027s pages in mlocked\n vmas leak through w/o PG_mlocked set [I don\u0027t know that it\n does], we should catch them later in try_to_unmap().
