Detailed Description

This protocol provides the services required to determine if a driver supports a given controller.

If a controller is supported, then it also provides routines to start and stop the controller.

◆ Supported

EFI_DRIVER_BINDING_SUPPORTED _EFI_DRIVER_BINDING_PROTOCOL::Supported

Definition at line 166 of file DriverBinding.h.

◆ Start

EFI_DRIVER_BINDING_START _EFI_DRIVER_BINDING_PROTOCOL::Start

Definition at line 167 of file DriverBinding.h.

◆ Stop

EFI_DRIVER_BINDING_STOP _EFI_DRIVER_BINDING_PROTOCOL::Stop

Definition at line 168 of file DriverBinding.h.

◆ Version

UINT32 _EFI_DRIVER_BINDING_PROTOCOL::Version

The version number of the UEFI driver that produced the EFI_DRIVER_BINDING_PROTOCOL.

This field is used by the EFI boot service ConnectController() to determine the order that driver's Supported() service will be used when a controller needs to be started. EFI Driver Binding Protocol instances with higher Version values will be used before ones with lower Version values. The Version values of 0x0- 0x0f and 0xfffffff0-0xffffffff are reserved for platform/OEM specific drivers. The Version values of 0x10- 0xffffffef are reserved for IHV-developed drivers.

◆ ImageHandle

EFI_HANDLE _EFI_DRIVER_BINDING_PROTOCOL::ImageHandle

The image handle of the UEFI driver that produced this instance of the EFI_DRIVER_BINDING_PROTOCOL.

◆ DriverBindingHandle

EFI_HANDLE _EFI_DRIVER_BINDING_PROTOCOL::DriverBindingHandle

The handle on which this instance of the EFI_DRIVER_BINDING_PROTOCOL is installed.

In most cases, this is the same handle as ImageHandle. However, for UEFI drivers that produce more than one instance of the EFI_DRIVER_BINDING_PROTOCOL, this value may not be the same as ImageHandle.
