The PCI_EXPRESS_CORRECTABLE_ERROR_STATUS structure describes a PCI Express (PCIe) correctable error status register of a PCIe advanced error reporting capability structure. The PCI_EXPRESS_CORRECTABLE_ERROR_MASK structure describes a PCI Express (PCIe) correctable error mask register of a PCIe advanced error reporting capability structure. The PCI_EXPRESS_CAPABILITY structure describes a PCI Express (PCIe) capability structure. The PCI_EXPRESS_CAPABILITIES_REGISTER structure describes a PCI Express (PCIe) capabilities register of a PCIe capability structure. The PCI_EXPRESS_BRIDGE_AER_CAPABILITY structure describes a PCI Express (PCIe) advanced error reporting capability structure for a PCIe bridge device. The PCI_EXPRESS_AER_CAPABILITY structure describes a PCI Express (PCIe) advanced error reporting capability structure. The PCI_EXPRESS_AER_CAPABILITIES structure describes a PCI Express (PCIe) advanced error capabilities and control register of a PCIe advanced error reporting capability structure. The PCI_DEVICE_PRESENT_INTERFACE structure is reserved for system use. The PCI_CAPABILITIES_HEADER structure defines a header that is present in every PCI capability structure. The SetVirtualFunctionData routine writes data to the PCI Express (PCIe) configuration space of a virtual function (VF) on a device that supports the single root I/O virtualization (SR-IOV) interface. The GetVirtualFunctionProbedBars routine returns the values of the PCI Express (PCIe) Base Address Registers (BARs) of a device that supports the single root I/O virtualization (SR-IOV) interface. The GetResources routine returns the resources that the PCI Express (PCIe) physical function (PF) requires in order to enable virtualization on a device that supports the single root I/O virtualization (SR-IOV) interface. A device that supports the single root I/O virtualization (SR-IOV) interface can expose one or more VFs on the PCI bus. The GetLocation routine returns the device location of a PCI Express (PCIe) virtual function (VF) on a PCI bus.
The GetVirtualFunctionData routine reads data from the PCI Express (PCIe) configuration space of a virtual function (VF) on a device that supports the single root I/O virtualization (SR-IOV) interface. Similarly, a PCIE Bridge acts a tiered root complex with a "Type 0 Configuration Table".The EnableVirtualization routine enables or disables virtualization for a PCI Express (PCIe) device that supports the single root I/O virtualization (SR-IOV) interface. Both the Type 1 and Type 0 configuration tables are set up by the Host Operating System that controls the Root Complex by a process known as enumeration and which acts to build a device memory map for the system by querying each bridge, and endpoint device connected on the bus network. In addition, each PCIE Endpoint device holds a master copy of their own memory space map in the host system memory as a 'Type 0 Configuration Table', this configuration table in each device allows the host to access the local memory of a PCIe device.
The PCIE Root Complex holds a master copy of a 'Type 1 Configuration Table' that defines the host memory space that is accessible from each Endpoint device.
