Overview of Virtual Function Initialization and Teardown

  • Artikel

This section provides an overview of the initialization and teardown sequence for PCI Express (PCIe) Virtual Functions (VFs). VFs are provided by a network adapter that supports single root I/O virtualization (SR-IOV).

This section includes the following topics:

Virtual Function Initialization Sequence

Virtual Function Teardown Sequence

For more information on VFs for SR-IOV network adapters, see SR-IOV Virtual Functions (VFs).

Note  Only the PF miniport driver can configure the network adapter's hardware resources, such as the VFs. The VF miniport driver cannot directly access most of the SR-IOV adapter's hardware resources. For more information, see Writing SR-IOV VF Miniport Drivers.
