◆ AtaBusDriverBindingStart()

EFI_STATUS EFIAPI AtaBusDriverBindingStart	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	Controller,
		IN EFI_DEVICE_PATH_PROTOCOL *	RemainingDevicePath
	)

Starts a device controller or a bus controller.

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. For a bus driver, if this parameter is NULL, then handles for all the children of Controller are created by this driver. If this parameter is not NULL and the first Device Path Node is not the End of Device Path Node, then only the handle for the child device specified by the first Device Path Node of RemainingDevicePath is created by this driver. If the first Device Path Node of RemainingDevicePath is the End of Device Path Node, no child handle is created by this driver.

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.

Definition at line 715 of file AtaBus.c.

◆ AtaBusDriverBindingStop()

EFI_STATUS EFIAPI AtaBusDriverBindingStop	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	Controller,
		IN UINTN	NumberOfChildren,
		IN EFI_HANDLE *	ChildHandleBuffer
	)

Stops a device controller or a bus controller.

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.
[in]	ChildHandleBuffer	An array of child handles to be freed. May be NULL if NumberOfChildren is 0.

Return values

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

Definition at line 897 of file AtaBus.c.

◆ AtaBusDriverBindingSupported()

EFI_STATUS EFIAPI AtaBusDriverBindingSupported	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	Controller,
		IN EFI_DEVICE_PATH_PROTOCOL *	RemainingDevicePath
	)

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.

This function checks to see if the driver specified by This supports the device specified by ControllerHandle. Drivers will typically use the device path attached to ControllerHandle and/or the services from the bus I/O abstraction attached to ControllerHandle to determine if the driver supports ControllerHandle. This function may be called many times during platform initialization. In order to reduce boot times, the tests performed by this function must be very small, and take as little time as possible to execute. This function must not change the state of any hardware devices, and this function must be aware that the device specified by ControllerHandle may already be managed by the same driver or a different driver. This function must match its calls to AllocatePages() with FreePages(), AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol(). Since ControllerHandle may have been previously started by the same driver, if a protocol is already in the opened state, then it must not be closed with CloseProtocol(). This is required to guarantee the state of ControllerHandle is not modified by this function.

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. For bus drivers, if this parameter is not NULL, then the bus driver must determine if the bus controller specified by ControllerHandle and the child controller specified by RemainingDevicePath are both supported by this bus driver.

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.

◆ AtaDiskInfoIdentify()

EFI_STATUS EFIAPI AtaDiskInfoIdentify	(	IN EFI_DISK_INFO_PROTOCOL *	This,
		IN OUT VOID *	IdentifyData,
		IN OUT UINT32 *	IdentifyDataSize
	)

Provides identify information for the controller type.

This function is used by the IDE bus driver to get identify data. Data format of Identify data is defined by the Interface GUID.

Parameters

[in]	This	Pointer to the EFI_DISK_INFO_PROTOCOL instance.
[in,out]	IdentifyData	Pointer to a buffer for the identify data.

		IN UINTN	PayloadBufferSize,
		OUT VOID *	PayloadBuffer,
		OUT UINTN *	PayloadTransferSize
	)

Send a security protocol command to a device that receives data and/or the result of one or more commands sent by SendData.

The ReceiveData function sends a security protocol command to the given MediaId. The security protocol command sent is defined by SecurityProtocolId and contains the security protocol specific data SecurityProtocolSpecificData. The function returns the data from the security protocol command in PayloadBuffer.

For devices supporting the SCSI command set, the security protocol command is sent using the SECURITY PROTOCOL IN command defined in SPC-4.

For devices supporting the ATA command set, the security protocol command is sent using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize is non-zero.

If the PayloadBufferSize is zero, the security protocol command is sent using the Trusted Non-Data command defined in ATA8-ACS.

If PayloadBufferSize is too small to store the available data from the security protocol command, the function shall copy PayloadBufferSize bytes into the PayloadBuffer and return EFI_WARN_BUFFER_TOO_SMALL.

If PayloadBuffer or PayloadTransferSize is NULL and PayloadBufferSize is non-zero, the function shall return EFI_INVALID_PARAMETER.

If the given MediaId does not support security protocol commands, the function shall return EFI_UNSUPPORTED. If there is no media in the device, the function returns EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the device, the function returns EFI_MEDIA_CHANGED.

If the security protocol fails to complete within the Timeout period, the function shall return EFI_TIMEOUT.

If the security protocol command completes without an error, the function shall return EFI_SUCCESS. If the security protocol command completes with an error, the function shall return EFI_DEVICE_ERROR.

Parameters

This	Indicates a pointer to the calling context.
MediaId	ID of the medium to receive data from. If there is no block IO protocol supported by the physical device, the value of MediaId is undefined.
Timeout	The timeout, in 100ns units, to use for the execution of the security protocol command. A Timeout value of 0 means that this function will wait indefinitely for the security protocol command to execute. If Timeout is greater than zero, then this function will return EFI_TIMEOUT if the time required to execute the receive data command is greater than Timeout.
SecurityProtocolId	The value of the "Security Protocol" parameter of the security protocol command to be sent.
SecurityProtocolSpecificData	The value of the "Security Protocol Specific" parameter of the security protocol command to be sent.

	)

Send a security protocol command to a device.

The SendData function sends a security protocol command containing the payload PayloadBuffer to the given MediaId. The security protocol command sent is defined by SecurityProtocolId and contains the security protocol specific data SecurityProtocolSpecificData. If the underlying protocol command requires a specific padding for the command payload, the SendData function shall add padding bytes to the command payload to satisfy the padding requirements.

For devices supporting the SCSI command set, the security protocol command is sent using the SECURITY PROTOCOL OUT command defined in SPC-4.

For devices supporting the ATA command set, the security protocol command is sent using one of the TRUSTED SEND commands defined in ATA8-ACS if PayloadBufferSize is non-zero. If the PayloadBufferSize is zero, the security protocol command is sent using the Trusted Non-Data command defined in ATA8-ACS.

If PayloadBuffer is NULL and PayloadBufferSize is non-zero, the function shall return EFI_INVALID_PARAMETER.

If the given MediaId does not support security protocol commands, the function shall return EFI_UNSUPPORTED. If there is no media in the device, the function returns EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the device, the function returns EFI_MEDIA_CHANGED.
