|
|
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.

the security protocol command to be sent.

sent.

|
|
Size in bytes of the payload data buffer.

for the security protocol command. The caller is

|
|
ownership of the buffer.

of the data written to the payload data buffer.

security protocol commands.
