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.

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

Parameters:
ThisA pointer to the EFI_BUS_SPECIFIC_DRIVER_ OVERRIDE_PROTOCOL instance.
DriverImageHandleOn 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_SUCCESSA bus specific override driver is returned in DriverImageHandle.
EFI_NOT_FOUNDThe end of the list of override drivers was reached. A bus specific override driver is not returned in DriverImageHandle.
EFI_INVALID_PARAMETERDriverImageHandle is not a handle that was returned on a previous call to GetDriver().
