.Sh NAME
|
|
.Nm PCI_IOV_UNINIT
|
|
.Nd disable SR-IOV on a PF device
|
|
.Sh SYNOPSIS
|
|
.In sys/bus.h
|
|
.In dev/pci/pci_iov.h
|
|
.Ft void
|
|
.Fn PCI_IOV_UNINIT "device_t dev"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn PCI_IOV_UNINIT
|
|
method is called by the PCI Single-Root I/O Virtualization (SR-IOV)
|
|
infrastructure when the user requests that SR-IOV be disabled on a Physical
|
|
Function (PF).
|
|
When this method is called, the PF driver must release any SR-IOV-related
|
|
resources that it has allocated and disable any device-specific SR-IOV
|
|
configuration in the device.
|
|
.Pp
|
|
This method will only be called following a successful call to
|
|
.Xr PCI_IOV_INIT .
|
|
It is not guaranteed that
|
|
.Xr PCI_IOV_ADD_VF
|
|
will have been called for any Virtual Function (VF) after the call to
|
|
.Xr PCI_IOV_INIT
|
|
and before the call to
|
|
.Nm .
