Typedef Documentation

typedef EFI_STATUS(EFIAPI * EFI_DRIVER_CONFIGURATION_FORCE_DEFAULTS)(IN EFI_DRIVER_CONFIGURATION_PROTOCOL *This, IN EFI_HANDLE ControllerHandle, IN EFI_HANDLE ChildHandle, IN UINT32 DefaultType, OUT EFI_DRIVER_CONFIGURATION_ACTION_REQUIRED *ActionRequired)

Forces a driver to set the default configuration options for a controller.

Parameters:
This A pointer to the EFI_DRIVER_CONFIGURATION_PROTOCOL instance.
ControllerHandle The handle of the controller to force default configuration options on.
ChildHandle The handle of the child controller to force default configuration options on This is an optional parameter that may be NULL. It will be NULL for device drivers. It will also be NULL for bus drivers that wish to force default configuration options for the bus controller. It will not be NULL for a bus driver that wishes to force default configuration options for one of its child controllers.
DefaultType The type of default configuration options to force on the controller specified by ControllerHandle and ChildHandle. See Table 9-1 for legal values. A DefaultType of 0x00000000 must be supported by this protocol.
ActionRequired A pointer to the action that the calling agent is required to perform when this function returns. See "Related Definitions" in Section 9.1 for a list of the actions that the calling agent is required to perform prior to accessing ControllerHandle again.
Return values:
EFI_SUCCESS The driver specified by This successfully forced the default configuration options on the controller specified by ControllerHandle and ChildHandle.
EFI_INVALID_PARAMETER ControllerHandle is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER ActionRequired is NULL.
EFI_UNSUPPORTED The driver specified by This does not support forcing the default configuration options on the controller specified by ControllerHandle and ChildHandle.
EFI_UNSUPPORTED The driver specified by This does not support the configuration type specified by DefaultType.
EFI_DEVICE_ERROR A device error occurred while attempt to force the default configuration options on the controller specified by ControllerHandle and ChildHandle.
EFI_OUT_RESOURCES There are not enough resources available to force the default configuration options on the controller specified by ControllerHandle and ChildHandle.

typedef EFI_STATUS(EFIAPI * EFI_DRIVER_CONFIGURATION_OPTIONS_VALID)(IN EFI_DRIVER_CONFIGURATION_PROTOCOL *This, IN EFI_HANDLE ControllerHandle, IN EFI_HANDLE ChildHandle)

Tests to see if a controller's current configuration options are valid.

Parameters:
This A pointer to the EFI_DRIVER_CONFIGURATION_PROTOCOL instance.
ControllerHandle The handle of the controller to test if it's current configuration options are valid.
ChildHandle The handle of the child controller to test if it's current configuration options are valid. This is an optional parameter that may be NULL. It will be NULL for device drivers. It will also be NULL for bus drivers that wish to test the configuration options for the bus controller. It will not be NULL for a bus driver that wishes to test configuration options for one of its child controllers.
Return values:
EFI_SUCCESS The controller specified by ControllerHandle and ChildHandle that is being managed by the driver specified by This has a valid set of configuration options.
EFI_INVALID_PARAMETER ControllerHandle is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid EFI_HANDLE.
EFI_UNSUPPORTED The driver specified by This is not currently managing the controller specified by ControllerHandle and ChildHandle.
EFI_DEVICE_ERROR The controller specified by ControllerHandle and ChildHandle that is being managed by the driver specified by This has an invalid set of configuration options.

typedef EFI_STATUS(EFIAPI * EFI_DRIVER_CONFIGURATION_SET_OPTIONS)(IN EFI_DRIVER_CONFIGURATION_PROTOCOL *This, IN EFI_HANDLE ControllerHandle, IN EFI_HANDLE ChildHandle, IN CHAR8 *Language, OUT EFI_DRIVER_CONFIGURATION_ACTION_REQUIRED *ActionRequired)

Allows the user to set controller specific options for a controller that a driver is currently managing.

Parameters:
This A pointer to the EFI_DRIVER_CONFIGURATION_PROTOCOL instance.
ControllerHandle The handle of the controller to set options on.
ChildHandle The handle of the child controller to set options on. This is an optional parameter that may be NULL. It will be NULL for device drivers, and for bus drivers that wish to set options for the bus controller. It will not be NULL for a bus driver that wishes to set options for one of its child controllers.
Language A pointer to a three character ISO 639-2 language identifier. This is the language of the user interface that should be presented to the user, and it must match one of the languages specified in SupportedLanguages. The number of languages supported by a driver is up to the driver writer.
ActionRequired A pointer to the action that the calling agent is required to perform when this function returns. See "Related Definitions" for a list of the actions that the calling agent is required to perform prior to accessing ControllerHandle again.
Return values:
EFI_SUCCESS The driver specified by This successfully set the configuration options for the controller specified by ControllerHandle..
EFI_INVALID_PARAMETER ControllerHandle is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER ActionRequired is NULL.
EFI_UNSUPPORTED The driver specified by This does not support setting configuration options for the controller specified by ControllerHandle and ChildHandle.
EFI_UNSUPPORTED The driver specified by This does not support the language specified by Language.
EFI_DEVICE_ERROR A device error occurred while attempt to set the configuration options for the controller specified by ControllerHandle and ChildHandle.
EFI_OUT_RESOURCES There are not enough resources available to set the configuration options for the controller specified by ControllerHandle and ChildHandle.
