10213 | * @phba: Pointer to HBA context object.. |
10214 | * @pring: Pointer to sli ring. | |
10215 | * @piocb: Pointer to command iocb. | |
10216 | * @prspiocbq: Pointer to response iocb. | |
10217 | * @timeout: Timeout in number of seconds. | |
10218 | * | |
10219 | * This function issues the iocb to firmware and waits for the | |
5a0916b4 JS |
10220 | * iocb to complete. The iocb_cmpl field of the shall be used |
10221 | * to handle iocbs which time out. If the field is NULL, the | |
10222 | * function shall free the iocbq structure. If more clean up is | |
10223 | * needed, the caller is expected to provide a completion function | |
10224 | * that will provide the needed clean up. If the iocb command is | |
10225 | * not completed within timeout seconds, the function will either | |
10226 | * free the iocbq structure (if iocb_cmpl == NULL) or execute the | |
10227 | * completion function set in the iocb_cmpl field and then return | |
10228 | * a status of IOCB_TIMEDOUT. The caller should not free the iocb | |
10229 | * resources if this function returns IOCB_TIMEDOUT. | |
e59058c4 JS |
10230 | * The function waits for the iocb completion using an |
10231 | * non-interruptible wait. | |
10232 | * This function will sleep while waiting for iocb completion. | |
10233 | * So, this function should not be called from any context which | |
10234 | * does not allow sleeping. Due to the same reason, this function | |
10235 | * cannot be called with interrupt disabled. | |
10236 | * This function assumes that the iocb completions occur while | |
10237 | * this function sleep. So, this function cannot be called from | |
10238 | * the thread which process iocb completion for this ring. | |
10239 | * This function clears the iocb_flag of the iocb object before | |
10240 | * issuing the iocb and the iocb completion handler sets this | |
10241 | * flag and wakes this thread when the iocb completes. | |
10242 | * The contents of the response iocb will be copied to prspiocbq | |
10243 | * by the completion handler when the command completes. | |
10244 | * This function returns IOCB_SUCCESS when success. | |
10245 | * This function is called with no lock held. | |
