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.neterion.com/products/x3100.html Physical Function driver for Intel 82576 NIC (based on drivers/net/igb/) will come in few weeks. Major changes from v7 to v8: 1, simplified the API for the PF driver 2, split the code and respin them against the latest tree Yu Zhao (7): PCI: initialize and release SR-IOV capability PCI: restore saved SR-IOV state PCI: reserve bus range for SR-IOV device PCI: add SR-IOV API for Physical Function driver PCI: handle SR-IOV Virtual Function Migration PCI: document SR-IOV sysfs entries PCI: manual for SR-IOV user and driver developer Documentation/ABI/testing/sysfs-bus-pci | 27 ++ Documentation/DocBook/kernel-api.tmpl | 1 + Documentation/PCI/pci-iov-howto.txt | 106 +++++ drivers/pci/Kconfig | 13 + drivers/pci/Makefile | 3 + drivers/pci/iov.c | 692 +++++++++++++++++++++++++++++++ drivers/pci/pci.c | 8 + drivers/pci/pci.h | 53 +++ drivers/pci/probe.c | 7 + include/linux/pci.h | 28 ++ include/linux/pci_regs.h | 33 ++ 11 files changed, 971 insertions(+), 0 deletions(-) create mode 100644 Documentation/PCI/pci-iov-howto.txt create mode 100644 drivers/pci/iov.c -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
