2 | This file implements ATA pass through transaction for ATA bus driver.\r | |
3 | \r | |
4 | This file implements the low level execution of ATA pass through transaction.\r | |
5 | It transforms the high level identity, read/write, reset command to ATA pass\r | |
c24097a5 | 6 | through command and protocol.\r |
7 | \r | |
3c063fed | 8 | NOTE: This file also implements the StorageSecurityCommandProtocol(SSP). For input\r |
58727f29 | 9 | parameter SecurityProtocolSpecificData, ATA spec has no explicitly definition\r |
10 | for Security Protocol Specific layout. This implementation uses big endian for\r | |
c24097a5 | 11 | Cylinder register.\r |

857 | This function performs one ATA pass through transaction to do a trust transfer from/to\r | |
858 | ATA device. It chooses the appropriate ATA command and protocol to invoke PassThru\r | |
859 | interface of ATA pass through.\r | |
860 | \r | |
861 | @param AtaDevice The ATA child device involved for the operation.\r | |
862 | @param Buffer The pointer to the current transaction buffer.\r | |
863 | @param SecurityProtocolId The value of the "Security Protocol" parameter of\r | |
864 | the security protocol command to be sent.\r | |
865 | @param SecurityProtocolSpecificData The value of the "Security Protocol Specific" parameter\r | |
866 | of the security protocol command to be sent.\r | |
867 | @param TransferLength The block number or sector count of the transfer.\r | |
868 | @param IsTrustSend Indicates whether it is a trust send operation or not.\r | |
869 | @param Timeout The timeout, in 100ns units, to use for the execution\r | |
870 | of the security protocol command. A Timeout value of 0\r | |
871 | means that this function will wait indefinitely for the\r | |
872 | security protocol command to execute. If Timeout is greater\r | |
873 | than zero, then this function will return EFI_TIMEOUT\r | |
874 | if the time required to execute the receive data command\r | |
875 | is greater than Timeout.\r | |
86d8e199 | 876 | @param TransferLengthOut A pointer to a buffer to store the size in bytes of the data\r |
877 | written to the buffer. Ignore it when IsTrustSend is TRUE.\r | |
c24097a5 | 878 | \r |
879 | @retval EFI_SUCCESS The data transfer is complete successfully.\r | |
