4.7.4 EFI Driver Model Example (Multiple Instances)
The following is the same as the first EFI Driver Model example, except it produces three
EFI_DRIVER_BINDING_PROTOCOL
instances. The first one is installed onto the driver’s
image handle. The other two are installed onto newly created handles.
extern EFI_GUID gEfiDriverBindingProtocolGuid;
EFI_BOOT_SERVICES_TABLE *gBS;
static EFI_DRIVER_BINDING_PROTOCOL mAbcDriverBindingA = {
AbcSupportedA,
AbcStartA,
AbcStopA,
1,
NULL,
NULL
};
static EFI_DRIVER_BINDING_PROTOCOL mAbcDriverBindingB = {
AbcSupportedB,
AbcStartB,
AbcStopB,
1,
NULL,
NULL
};
static EFI_DRIVER_BINDING_PROTOCOL mAbcDriverBindingC = {
AbcSupportedC,
AbcStartC,
AbcStopC,
1,
NULL,
NULL
};
