A typical SR-IOV\ndevice can support multiple VFs whose BARs must be in a contiguous region,\neffectively an array of VF BARs. The BAR reports the size requirement\nfor a single VF. We calculate the full range needed by simply multiplying\nthe VF BAR size with the number of possible VFs and create a resource\nspanning the full range.\n\nThis all seems sane enough except it artificially inflates the alignment\nrequirement for the VF BAR. The VF BAR need only be aligned to the size\nof a single BAR not the contiguous range of VF BARs. This can cause us\nto fail to allocate resources for the BAR despite the fact that we\nactually have enough space.\n\nThis patch adds a thin PCI specific layer over the generic\nresource_alignment() function which is aware of the special nature of\nVF BARs and does sorting and allocation based on the smaller alignment\nrequirement.\n\nI recognize that while resource_alignment is generic, it\u0027s basically a\nPCI helper. An alternative to this patch is to add PCI VF BAR specific\ninformation to struct resource. I opted for the extra layer rather than\nadding such PCI specific information to struct resource. This does\nhave the slight downside that we don\u0027t cache the BAR size and re-read\nfor each alignment query (happens a small handful of times during boot\nfor each VF BAR).\n\nSigned-off-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Matthew Wilcox \u003cmatthew@wil.cx\u003e\nCc: Yu Zhao \u003cyu.zhao@intel.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\n" }, { "commit": "79896cf42f6a96d7e14f2dc3473443d68d74031d", "tree": "bf4aa83fedfbe51d9a2a60d03007ec69de5a0cd2", "parents": [ "0dd8486b5cfe8048e0613334659d9252ecd1b08a" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Aug 02 14:04:19 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun Aug 02 14:10:18 2009 -0700" }, "message": "Make pci_claim_resource() use request_resource() rather than insert_resource()\n\nThis function has traditionally used \"insert_resource()\", because before\ncommit cebd78a8c5 (\"Fix pci_claim_resource\") it used to just insert the\nresource into whatever root resource tree that was indicated by\n\"pcibios_select_root()\".\n\nSo there Matthew fixed it to actually look up the proper parent\nresource, which means that now it\u0027s actively wrong to then traverse the\nresource tree any more: we already know exactly where the new resource\nshould go.\n\nAnd when we then did commit a76117dfd6 (\"x86: Use pci_claim_resource\"),\nwhich changed the x86 PCI code from the open-coded\n\n\tpr \u003d pci_find_parent_resource(dev, r);\n\tif (!pr || request_resource(pr, r) \u003c 0) {\n\nto using\n\n\tif (pci_claim_resource(dev, idx) \u003c 0) {\n\nthat \"insert_resource()\" now suddenly became a problem, and causes a\nregression covered by\n\n\thttp://bugzilla.kernel.org/show_bug.cgi?id\u003d13891\n\nwhich this fixes.\n\nReported-and-tested-by: Rafael J.

This fails because in the PIIX4 these BAR registers have\nimplicitly assumed values and read back as zero; it used to work because\nthe kernel used to just write zero to that register the read back value did\nmatch what was written.\n\nThe fix is a new resource flag IORESOURCE_PCI_FIXED used to mark a resource\nas non-movable. This will also be useful to keep other import system\nresources from being moved around - for example system consoles on PCI\nbusses.\n\n[akpm@osdl.org: cleanup]\nSigned-off-by: Ralf Baechle \u003cralf@linux-mips.org\u003e\nAcked-by: Alan Cox \u003calan@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "e31dd6e4520439ceae4753f32dd2da2c345e929a", "tree": "fea87cfb0077135c6dcaf7849e518ee31733b0fc", "parents": [ "d75fc8bbccf7c019994bcfd6255d5b56335ed21d" ], "author": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Jun 12 17:06:02 2006 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Jun 27 09:24:00 2006 -0700" }, "message": "[PATCH] 64bit resource: change pci core and arch code to use resource_size_t\n\nBased on a patch series originally from Vivek Goyal \u003cvgoyal@in.ibm.com\u003e\n\nCc: Vivek Goyal \u003cvgoyal@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "1396a8c3f7cec9f5e0d00bd089be21fc468f0f1c", "tree": "b96018459e26a24e20221f0bb7d5bb25d6608147", "parents": [ "7c7459d1f91abdf1e31ef80cad526e83e8b8ba4e" ], "author": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Jun 12 15:14:29 2006 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Tue Jun 27 09:23:58 2006 -0700" }, "message": "[PATCH] 64bit resource: fix up printks for resources in pci core and hotplug drivers\n\nThis is needed if we wish to change the size of the resource structures.\n\nBased on an original patch from Vivek Goyal \u003cvgoyal@in.ibm.com\u003e\n\nCc: Vivek Goyal \u003cvgoyal@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "75acfecaa031c0e1bc412cee4fe58ba49ff3406c", "tree": "39f784dcc17a093e80463163867ec0e554942453", "parents": [ "ea28502d5d0fc624777a8a6b4d6865d282055b05" ], "author": { "name": "Kumar Gala", "email": "galak@kernel.crashing.org", "time": "Mon May 01 10:43:46 2006 -0500" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Jun 21 11:59:59 2006 -0700" }, "message": "[PATCH] PCI: Add pci_assign_resource_fixed -- allow fixed address assignments\n\nPCI: Add pci_assign_resource_fixed -- allow fixed address assignments\n\nOn some embedded systems the PCI address for hotplug devices are not only\nknown a priori but are required to be at a given PCI address for other\nmaster in the system to be able to access.\n\nAn example of such a system would be an FPGA which is setup from user space\nafter the system has booted.

These resources get linked into the\n iomem/ioport tree when PCI controllers are probed.\n\n So the hierarchy looks like this:\n\n iomem --|\n\t PCI controller 1 MEM space --|\n\t\t\t\t device 1\n\t\t\t\t\tdevice 2\n\t\t\t\t\tetc.\n\t PCI controller 2 MEM space --|\n\t\t\t\t ...\n ioport --|\n PCI controller 1 IO space --|\n\t\t\t\t\t...\n PCI controller 2 IO space --|\n\t\t\t\t\t...\n\n You get the idea. The drivers/pci/setup-res.c code allocates\n using plain iomem_space and ioport_space as the root, so that\n wouldn\u0027t work with the above setup.\n\n So I added a pcibios_select_root() that is used to handle this.\n It uses the PCI controller struct\u0027s io_space and mem_space on\n sparc64, and io{port,mem}_resource on every other platform to\n keep current behavior.\n\n2) quirk_io_region() is buggy. It takes in raw BUS view addresses\n and tries to use them as a PCI resource.\n\n pci_claim_resource() expects the resource to be fully formed when\n it gets called. The sparc64 implementation would do the translation\n but that\u0027s absolutely wrong, because if the same resource gets\n released then re-claimed we\u0027ll adjust things twice.\n\n So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource()\n conversion before passing it on to pci_claim_resource().\n\n3) I was mistakedly __init\u0027ing the function methods the PCI controller\n drivers provide on sparc64 to implement some parts of these\n routines. This was, of course, easy to fix.\n\nSo we end up with the following, and that nasty SPARC64 makefile\nifdef in drivers/pci/Makefile is finally zapped.\n\nSigned-off-by: David S.
