◆ ArpComponentNameGetControllerName()

EFI_STATUS EFIAPI ArpComponentNameGetControllerName	(	IN EFI_COMPONENT_NAME_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN EFI_HANDLE ChildHandle	OPTIONAL,
		IN CHAR8 *	Language,
		OUT CHAR16 **	ControllerName
	)

Retrieves a Unicode string that is the user readable name of the controller that is being managed by a driver.

This function retrieves the user readable name of the controller specified by ControllerHandle and ChildHandle in the form of a Unicode string. If the driver specified by This has a user readable name in the language specified by Language, then a pointer to the controller name is returned in ControllerName, and EFI_SUCCESS is returned. If the driver specified by This is not currently managing the controller specified by ControllerHandle and ChildHandle, then EFI_UNSUPPORTED is returned. If the driver specified by This does not support the language specified by Language, then EFI_UNSUPPORTED is returned.

Parameters

[in]	This	A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or EFI_COMPONENT_NAME_PROTOCOL instance.
[in]	ControllerHandle	The handle of a controller that the driver specified by This is managing. This handle specifies the controller whose name is to be returned.
[in]	ChildHandle	The handle of the child controller to retrieve the name of. This is an optional parameter that may be NULL. It will be NULL for device drivers. It will also be NULL for a bus drivers that wish to retrieve the name of the bus controller. It will not be NULL for a bus driver that wishes to retrieve the name of a child controller.
[in]	Language	A pointer to a Null-terminated ASCII string array indicating the language. This is the language of the driver name that the caller is requesting, 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. Language is specified in RFC 4646 or ISO 639-2 language code format.
[out]	ControllerName	A pointer to the Unicode string to return. This Unicode string is the name of the controller specified by ControllerHandle and ChildHandle in the language specified by Language from the point of view of the driver specified by This.

Return values

EFI_SUCCESS	The Unicode string for the user readable name in the language specified by Language for the driver specified by This was returned in DriverName.
EFI_INVALID_PARAMETER	ControllerHandle is NULL.
EFI_INVALID_PARAMETER	ChildHandle is not NULL and it is not a valid EFI_HANDLE.

◆ ArpComponentNameGetDriverName()

EFI_STATUS EFIAPI ArpComponentNameGetDriverName	(	IN EFI_COMPONENT_NAME_PROTOCOL *	This,
		IN CHAR8 *	Language,
		OUT CHAR16 **	DriverName
	)

Retrieves a Unicode string that is the user readable name of the driver.

This function retrieves the user readable name of a driver in the form of a Unicode string. If the driver specified by This has a user readable name in the language specified by Language, then a pointer to the driver name is returned in DriverName, and EFI_SUCCESS is returned. If the driver specified by This does not support the language specified by Language, then EFI_UNSUPPORTED is returned.

Parameters

[in]	This	A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or EFI_COMPONENT_NAME_PROTOCOL instance.
[in]	Language	A pointer to a Null-terminated ASCII string array indicating the language. This is the language of the driver name that the caller is requesting, 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. Language is specified in RFC 4646 or ISO 639-2 language code format.

◆ ArpDriverBindingStart()

EFI_STATUS EFIAPI ArpDriverBindingStart	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN EFI_DEVICE_PATH_PROTOCOL *RemainingDevicePath	OPTIONAL
	)

Start this driver on ControllerHandle.

The Start() function is designed to be invoked from the EFI boot service ConnectController(). As a result, much of the error checking on the parameters to Start() has been moved into this common boot service. It is legal to call Start() from other locations, but the following calling restrictions must be followed or the system behavior will not be deterministic.

ControllerHandle must be a valid EFI_HANDLE.
If RemainingDevicePath is not NULL, then it must be a pointer to a naturally aligned EFI_DEVICE_PATH_PROTOCOL.
Prior to calling Start(), the Supported() function for the driver specified by This must have been called with the same calling parameters, and Supported() must have returned EFI_SUCCESS.

Parameters

[in]	This	A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
[in]	ControllerHandle	The handle of the controller to start. This handle must support a protocol interface that supplies an I/O abstraction to the driver.
[in]	RemainingDevicePath	A pointer to the remaining portion of a device path. This parameter is ignored by device drivers, and is optional for bus drivers.

Return values

EFI_SUCCESS	The device was started.
EFI_DEVICE_ERROR	The device could not be started due to a device error. Currently not implemented.
EFI_OUT_OF_RESOURCES	The request could not be completed due to a lack of resources.
Others	The driver failed to start the device.

◆ ArpDriverBindingStop()

EFI_STATUS EFIAPI ArpDriverBindingStop	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN UINTN	NumberOfChildren,
		IN EFI_HANDLE *	ChildHandleBuffer
	)

Stop this driver on ControllerHandle.

Release the control of this controller and remove the IScsi functions. The Stop() function is designed to be invoked from the EFI boot service DisconnectController(). As a result, much of the error checking on the parameters to Stop() has been moved into this common boot service. It is legal to call Stop() from other locations, but the following calling restrictions must be followed or the system behavior will not be deterministic.

ControllerHandle must be a valid EFI_HANDLE that was used on a previous call to this same driver's Start() function.
The first NumberOfChildren handles of ChildHandleBuffer must all be a valid EFI_HANDLE. In addition, all of these handles must have been created in this driver's Start() function, and the Start() function must have called OpenProtocol() on ControllerHandle with an Attribute of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.

Parameters

[in]	This	A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
[in]	ControllerHandle	A handle to the device being stopped. The handle must support a bus specific I/O protocol for the driver to use to stop the device.
[in]	NumberOfChildren	The number of child device handles in ChildHandleBuffer. Not used.
[in]	ChildHandleBuffer	An array of child handles to be freed. May be NULL if NumberOfChildren is 0.Not used.

Return values

EFI_SUCCESS	The device was stopped.
EFI_DEVICE_ERROR	The device could not be stopped due to a device error.

◆ ArpDriverBindingSupported()

EFI_STATUS EFIAPI ArpDriverBindingSupported	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN EFI_DEVICE_PATH_PROTOCOL *RemainingDevicePath	OPTIONAL
	)

Tests to see if this driver supports a given controller.

If a child device is provided, it further tests to see if this driver supports creating a handle for the specified child device.

Parameters

[in]	This	A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
[in]	ControllerHandle	The handle of the controller to test. This handle must support a protocol interface that supplies an I/O abstraction to the driver.
[in]	RemainingDevicePath	A pointer to the remaining portion of a device path. This parameter is ignored by device drivers, and is optional for bus drivers.

Return values

EFI_SUCCESS	The device specified by ControllerHandle and RemainingDevicePath is supported by the driver specified by This.
EFI_ALREADY_STARTED	The device specified by ControllerHandle and RemainingDevicePath is already being managed by the driver specified by This.
EFI_ACCESS_DENIED	The device specified by ControllerHandle and RemainingDevicePath is already being managed by a different driver or an application that requires exclusive access. Currently not implemented.
EFI_UNSUPPORTED	The device specified by ControllerHandle and RemainingDevicePath is not supported by the driver specified by This.

◆ ArpServiceBindingCreateChild()

EFI_STATUS EFIAPI ArpServiceBindingCreateChild	(	IN EFI_SERVICE_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE *	ChildHandle
	)

Creates a child handle and installs a protocol.

The CreateChild() function installs a protocol on ChildHandle. If ChildHandle is a pointer to NULL, then a new handle is created and returned in ChildHandle. If ChildHandle is not a pointer to NULL, then the protocol installs on the existing ChildHandle.

Parameters

This	Pointer to the EFI_SERVICE_BINDING_PROTOCOL instance.
ChildHandle	Pointer to the handle of the child to create. If it is NULL, then a new handle is created. If it is a pointer to an existing UEFI handle, then the protocol is added to the existing UEFI handle.

Return values

EFI_SUCCESS	The protocol was added to ChildHandle.
EFI_INVALID_PARAMETER	ChildHandle is NULL.
EFI_OUT_OF_RESOURCES	There are not enough resources available to create the child
other	The child handle was not created

◆ ArpServiceBindingDestroyChild()

EFI_STATUS EFIAPI ArpServiceBindingDestroyChild	(	IN EFI_SERVICE_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ChildHandle
	)

Destroys a child handle with a protocol installed on it.

The DestroyChild() function does the opposite of CreateChild(). It removes a protocol that was installed by CreateChild() from ChildHandle. If the removed protocol is the last protocol on ChildHandle, then ChildHandle is destroyed.

Parameters

This	Pointer to the EFI_SERVICE_BINDING_PROTOCOL instance.
ChildHandle	Handle of the child to destroy

Return values

EFI_SUCCESS	The protocol was removed from ChildHandle.
EFI_UNSUPPORTED	ChildHandle does not support the protocol that is being removed.
EFI_INVALID_PARAMETER	Child handle is NULL.
EFI_ACCESS_DENIED	The protocol could not be removed from the ChildHandle because its services are being used.
other	The child handle was not destroyed
