aeb49322 | 18 | Sends a SCSI Request Packet to a SCSI device that is attached to the SCSI channel. This function \r |
19 | supports both blocking I/O and nonblocking I/O. The blocking I/O functionality is required, and the\r | |
20 | nonblocking I/O functionality is optional. \r | |
21 | \r | |
22 | @param[in] This A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance.\r | |
23 | @param[in] Target The Target is an array of size TARGET_MAX_BYTES and it represents\r | |
24 | the id of the SCSI device to send the SCSI Request Packet. Each\r | |
25 | transport driver may chose to utilize a subset of this size to suit the needs\r | |
26 | of transport target representation. For example, a Fibre Channel driver\r | |
27 | may use only 8 bytes (WWN) to represent an FC target.\r | |
28 | @param[in] Lun The LUN of the SCSI device to send the SCSI Request Packet.\r | |
29 | @param[in, out] Packet A pointer to the SCSI Request Packet to send to the SCSI device\r | |
30 | specified by Target and Lun.\r | |
31 | @param[in] Event If nonblocking I/O is not supported then Event is ignored, and blocking\r | |
32 | I/O is performed. If Event is NULL, then blocking I/O is performed. If\r | |
33 | Event is not NULL and non blocking I/O is supported, then\r | |
34 | nonblocking I/O is performed, and Event will be signaled when the\r | |
35 | SCSI Request Packet completes.\r | |
36 | \r | |
37 | @retval EFI_SUCCESS The SCSI Request Packet was sent by the host. For bi-directional\r | |
38 | commands, InTransferLength bytes were transferred from\r | |
39 | InDataBuffer. For write and bi-directional commands,\r | |
40 | OutTransferLength bytes were transferred by\r | |
41 | OutDataBuffer.\r | |
42 | @retval EFI_BAD_BUFFER_SIZE The SCSI Request Packet was not executed. The number of bytes that\r | |
43 | could be transferred is returned in InTransferLength. For write\r | |
44 | and bi-directional commands, OutTransferLength bytes were\r | |
45 | transferred by OutDataBuffer. Currently not implemeted. \r | |
46 | @retval EFI_NOT_READY The SCSI Request Packet could not be sent because there are too many\r | |
47 | SCSI Request Packets already queued. The caller may retry again later. \r | |
48 | @retval EFI_DEVICE_ERROR A device error occurred while attempting to send the SCSI Request\r | |
49 | Packet. \r | |
50 | @retval EFI_INVALID_PARAMETER Target, Lun, or the contents of ScsiRequestPacket are invalid.\r | |
51 | @retval EFI_UNSUPPORTED The command described by the SCSI Request Packet is not supported\r | |
52 | by the host adapter. This includes the case of Bi-directional SCSI\r | |
53 | commands not supported by the implementation. The SCSI Request\r | |
54 | Packet was not sent, so no additional status information is available.\r | |
55 | Currently not implemeted.\r | |
56 | @retval EFI_TIMEOUT A timeout occurred while waiting for the SCSI Request Packet to execute. \r | |
