UINT32 | Version |
EFI_HANDLE | ImageHandle |
EFI_HANDLE | 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.
The image handle of the UEFI driver that produced this instance of the EFI_DRIVER_BINDING_PROTOCOL.
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.
