Detailed Description

Bus Specific Driver Override protocol as defined in the UEFI 2.0 specification.

Bus drivers that have a bus specific algorithm for matching drivers to controllers are required to produce this protocol for each controller. For example, a PCI Bus Driver will produce an instance of this protocol for every PCI controller that has a PCI option ROM that contains one or more UEFI drivers. The protocol instance is attached to the handle of the PCI controller.

◆ EFI_BUS_SPECIFIC_DRIVER_OVERRIDE_GET_DRIVER

typedef EFI_STATUS(EFIAPI * EFI_BUS_SPECIFIC_DRIVER_OVERRIDE_GET_DRIVER) (IN EFI_BUS_SPECIFIC_DRIVER_OVERRIDE_PROTOCOL *This, IN OUT EFI_HANDLE *DriverImageHandle)

Uses a bus specific algorithm to retrieve a driver image handle for a controller.

Parameters

This	A pointer to the EFI_BUS_SPECIFIC_DRIVER_ OVERRIDE_PROTOCOL instance.
DriverImageHandle	On input, a pointer to the previous driver image handle returned by GetDriver(). On output, a pointer to the next driver image handle. Passing in a NULL, will return the first driver image handle.

Return values

EFI_SUCCESS	A bus specific override driver is returned in DriverImageHandle.
EFI_NOT_FOUND	The end of the list of override drivers was reached. A bus specific override driver is not returned in DriverImageHandle.
EFI_INVALID_PARAMETER	DriverImageHandle is not a handle that was returned on a previous call to GetDriver().
