Routine Description:
|
|
|
|
This function registers the PCI IO device. It creates a handle for this PCI IO device
|
|
(if the handle does not exist), attaches appropriate protocols onto the handle, does
|
|
necessary initialization, and sets up parent/child relationship with its bus controller.
|
|
|
|
Arguments:
|
|
|
|
Controller - An EFI handle for the PCI bus controller.
|
|
PciIoDevice - A PCI_IO_DEVICE pointer to the PCI IO device to be registered.
|
|
Handle - A pointer to hold the EFI handle for the PCI IO device.
|
|
|
|
Returns:
|
|
|
|
EFI_SUCCESS - The PCI device is successfully registered.
|
|
Others - An error occurred when registering the PCI device.
