Tests to see if this driver supports a given controller. If a child device is provided,

|

|
|

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.

@param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.

@param[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.

||
|
@param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This

parameter is ignored by device drivers, and is optional for bus

the bus driver must determine if the bus controller specified

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,

|

1. ControllerHandle must be a valid EFI_HANDLE.

2. If RemainingDevicePath is not NULL, then it must be a pointer to a naturally aligned

an I/O abstraction to the driver.

@param[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

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.

@param MediaId ID of the medium to receive data from.
|

|
@param 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.
|

@param SecurityProtocolId The value of the "Security Protocol" parameter of
|

|
the security protocol command to be sent.

|
||
|
of the security protocol command to be sent.
|

@param PayloadBufferSize Size in bytes of the payload data buffer.
|
||
|
@param PayloadBuffer A pointer to a destination buffer to store the security
|

|
protocol command specific payload data for the security
|
||
|
protocol command. The caller is responsible for having
|
||
|
either implicit or explicit ownership of the buffer.

@param PayloadTransferSize A pointer to a buffer to store the size in bytes of the
|

data written to the payload data buffer.

@retval EFI_SUCCESS The security protocol command completed successfully.
|

@retval EFI_WARN_BUFFER_TOO_SMALL The PayloadBufferSize was too small to store the available

data from the device. The PayloadBuffer contains the truncated data.

@retval EFI_DEVICE_ERROR The security protocol command completed with an error.
