/** | |
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 DeviceIndex. | |
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 DeviceIndex does not support security protocol commands, the function | |
shall return EFI_UNSUPPORTED. | |
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[in] This The PPI instance pointer. | |
@param[in] DeviceIndex Specifies the storage security device to which the | |
function wants to talk. Because the driver that | |
implements Storage Security Command PPIs will manage | |
multiple storage devices, the PPIs that want to talk | |
to a single device must specify the device index | |
that was assigned during the enumeration process. | |
This index is a number from one to NumberofDevices. | |
@param[in] 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[in] SecurityProtocolId | |
The value of the "Security Protocol" parameter of | |
the security protocol command to be sent. | |
@param[in] SecurityProtocolSpecificData | |
The value of the "Security Protocol Specific" | |
parameter of the security protocol command to be | |
sent. | |
@param[in] PayloadBufferSize | |
Size in bytes of the payload data buffer. | |
@param[out] 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[out] 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_UNSUPPORTED The given DeviceIndex does not support | |
security protocol commands. | |
@retval EFI_DEVICE_ERROR The security protocol command completed | |
with an error. | |
@retval EFI_INVALID_PARAMETER The PayloadBuffer or PayloadTransferSize | |
is NULL and PayloadBufferSize is non-zero. | |
@retval EFI_TIMEOUT A timeout occurred while waiting for the | |
security protocol command to execute. | |

The SendData function sends a security protocol command containing the payload | |
PayloadBuffer to the given DeviceIndex. The security protocol command sent is | |

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. | |
