Greetings, Following patches are intended to support SR-IOV capability in the Linux kernel. With these patches, people can turn a PCI device with the capability into multiple ones from software perspective, which will benefit KVM and achieve other purposes such as QoS, security, and etc. SR-IOV specification can be found at: http://www.pcisig.com/members/downloads/specifications/iov/sr-iov1.0_11Sep07.pdf (it requires membership.) Devices that support SR-IOV are available from following vendors: http://download.intel.com/design/network/ProdBrf/320025.pdf http://www.myri.com/vlsi/Lanai_Z8ES_Datasheet.pdf http://www.neterion.com/products/pdfs/X3100ProductBrief.pdf Physical Function driver patches for Intel 82576 NIC are available: http://patchwork.kernel.org/patch/8063/ http://patchwork.kernel.org/patch/8064/ http://patchwork.kernel.org/patch/8065/ http://patchwork.kernel.org/patch/8066/ Major changes from v9 to v10: 1, minor fix in pci_restore_iov_state(). 2, respin against the latest tree.
