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. [PATCH 1/8 v4] PCI: define PCI resource names in a 'enum' [PATCH 2/8 v4] PCI: export __pci_read_base [PATCH 3/8 v4] PCI: export pci_alloc_child_bus [PATCH 4/8 v4] PCI: add a wrapper for resource_alignment [PATCH 5/8 v4] PCI: add a new function to map BAR offset [PATCH 6/8 v4] PCI: support the SR-IOV capability [PATCH 7/8 v4] PCI: reserve bus range for the SR-IOV device [PATCH 8/8 v4] PCI: document the changes --- b/Documentation/DocBook/kernel-api.tmpl | 1 b/Documentation/PCI/pci-iov-howto.txt | 223 ++++++++ b/drivers/pci/Kconfig | 12 b/drivers/pci/Makefile | 2 b/drivers/pci/iov.c | 853 ++++++++++++++++++++++++++++++++ b/drivers/pci/pci-sysfs.c | 4 b/drivers/pci/pci.c | 19 b/drivers/pci/pci.h | 9 b/drivers/pci/probe.c | 2 b/drivers/pci/proc.c | 7 b/drivers/pci/setup-bus.c | 4 b/drivers/pci/setup-res.c | 8 b/include/linux/pci.h | 38 - b/include/linux/pci_regs.h | 22 drivers/pci/iov.c | 24 drivers/pci/pci-sysfs.c | 4 drivers/pci/pci.c | 61 ++ drivers/pci/pci.h | 65 ++ drivers/pci/probe.c | 39 - drivers/pci/setup-res.c | 14 include/linux/pci.h | 57 ++ 21 files changed, 1397 insertions(+), 71 deletions(-) --- Single Root I/O Virtualization (SR-IOV) capability defined by PCI-SIG is intended to enable multiple system software to share PCI hardware resources. PCI device that supports this capability can be extended to one Physical Functions plus multiple Virtual Functions. Physical Function, which could be considered as the "real" PCI device, reflects the hardware instance and manages all physical resources. Virtual Functions are associated with a Physical Function and shares physical resources with the Physical Function.Software can control allocation of Virtual Functions via registers encapsulated in the capability structure. SR-IOV specification can be found at http://www.pcisig.com/members/downloads/specifications/iov/sr-iov1.0_11Sep07.pdf Devices that support SR-IOV are available from following vendors: http://download.intel.com/design/network/ProdBrf/320025.pdf http://www.netxen.com/products/chipsolutions/NX3031.html http://www.neterion.com/products/x3100.html -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
