SR-IOV Interfaces Summary

The following table lists the Oracle Solaris interfaces that are available to the SR-IOV drivers. The interfaces are called to obtain PF and VF parameters, to configure VFs, and to export the configuration parameters to any calling applications.

Note - All the interfaces listed in the table with the exception of pciv_send() are applicable only for PF drivers.

Table 22 Interfaces for SR-IOV Drivers

Interface Name	Description
`pci_param_get`(9F)	Used by PCI device drivers to get the name-value pair list of the currently configured parameters
`pci_param_free`(9F)	Must be called by the device driver after they have obtained the device parameters by using the `param` handle. This call frees up the resources allocated by the `pci_param_get()` and `pci_param_get_ioctl()` interfaces.
`pci_plist_get`(9F)	Used by the SR-IOV device drivers to get the name-value pair list for the PF devices.
`pci_plist_getvf`(9F)	Used by the SR-IOV device drivers to get the name-value pair list for the VF devices.
`pci_param_get_ioctl`(9F)	A helper function to SR-IOV device drivers to extract the parameters for the PF and VF devices from the `arg` argument if the drivers implement the ioctl `IOV_VALIDATE_PARAM.`
`pciv_vf_config`(9F)	Used by PF drivers to obtain VF configuration parameters and to configure their VFs.
`pci_plist_lookup`(9F)	Used to obtain the parameters for PF and VF from the list obtained from the `pci_plist_get()` and `pci_plist_getvf()` interfaces.
`pciv_send`(9F)	Used by the PF and VF drivers to transmit information.
`ddi_cb_register`(9F)	Callback registration mechanism interfaces.

Driver Ioctls

The SR-IOV driver ioctls are used to identify the device–specific parameters that can be configured by the administrator and to validate a specific configuration before it is applied. The following ioctls and their data structures are defined.
