193\r
194 Routine Description:\r
195 Sends a SCSI Request Packet to the SCSI Controller for execution.\r
196\r
197 Arguments:\r
198 This - Protocol instance pointer.\r
199 Packet - The SCSI request packet to send to the SCSI\r
200 Controller specified by the device handle.\r
201 Event - If the SCSI bus where the SCSI device is attached\r
202 does not support non-blocking I/O, then Event is\r
203 ignored, and blocking I/O is performed.\r
204 If Event is NULL, then blocking I/O is performed.\r
205 If Event is not NULL and non-blocking I/O is\r
206 supported, then non-blocking I/O is performed,\r
207 and Event will be signaled when the SCSI Request\r
208 Packet completes.\r
209\r
210 Returns:\r
211 EFI_SUCCESS - The SCSI Request Packet was sent by the host\r
212 successfully, and TransferLength bytes were\r
213 transferred to/from DataBuffer.See\r
214 HostAdapterStatus, TargetStatus,\r
215 SenseDataLength, and SenseData in that order\r
216 for additional status information.\r
217 EFI_BAD_BUFFER_SIZE - The SCSI Request Packet was executed,\r
218 but the entire DataBuffer could not be transferred.\r
219 The actual number of bytes transferred is returned\r
220 in TransferLength. See HostAdapterStatus,\r
221 TargetStatus, SenseDataLength, and SenseData in\r
222 that order for additional status information.\r
223 EFI_NOT_READY - The SCSI Request Packet could not be sent because\r
224 there are too many SCSI Command Packets already\r
225 queued.The caller may retry again later.\r
226 EFI_DEVICE_ERROR - A device error occurred while attempting to send\r
227 the SCSI Request Packet. See HostAdapterStatus,\r
228 TargetStatus, SenseDataLength, and SenseData in\r
229 that order for additional status information.\r
230 EFI_INVALID_PARAMETER - The contents of CommandPacket are invalid.\r
231 The SCSI Request Packet was not sent, so no\r
232 additional status information is available.\r
233 EFI_UNSUPPORTED - The command described by the SCSI Request Packet\r
234 is not supported by the SCSI initiator(i.e., SCSI\r
235 Host Controller). The SCSI Request Packet was not\r
236 sent, so no additional status information is\r
237 available.\r
238 EFI_TIMEOUT - A timeout occurred while waiting for the SCSI\r
239 Request Packet to execute. See HostAdapterStatus,\r
240 TargetStatus, SenseDataLength, and SenseData in\r
241 that order for additional status information.\r
