29.Sh NAME
30.Nm PCI_IOV_UNINIT
31.Nd disable SR-IOV on a PF device
32.Sh SYNOPSIS
33.In sys/bus.h
34.In dev/pci/pci_iov.h
35.Ft void
36.Fn PCI_IOV_UNINIT "device_t dev"
37.Sh DESCRIPTION
38The
39.Fn PCI_IOV_UNINIT
40method is called by the PCI Single-Root I/O Virtualization (SR-IOV)
41infrastructure when the user requests that SR-IOV be disabled on a Physical
42Function (PF).
43When this method is called, the PF driver must release any SR-IOV-related
44resources that it has allocated and disable any device-specific SR-IOV
45configuration in the device.
46.Pp
47This method will only be called following a successful call to
48.Xr PCI_IOV_INIT 9 .
49It is not guaranteed that
50.Xr PCI_IOV_ADD_VF 9
51will have been called for any Virtual Function (VF) after the call to
52.Xr PCI_IOV_INIT 9
53and before the call to
54.Nm .
