Description
The EFI_DRIVER_DIAGNOSTICS_PROTOCOL is used by a platform management utility to
allow the user to run driver specific diagnostics on a controller. This protocol is optionally attached
to the image handle of driver in the driver’s entry point. The platform management utility can
collect all the
EFI_DRIVER_DISAGNOTICS_PROTOCOL instances present in the system, and
present the user with a menu of the controllers that have diagnostic capabilities. This platform
management utility is invoked through a platform component such as the EFI Boot Manager.
