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. [PATCH 1/8 v4] PCI: define PCI resource names in a 'enum' [PATCH 2/8 v4] PCI: export __pci_read_base
