| * General explenations: |
| * ===================== |
| * 1) This SM calls some functions that may complete their processing in another context. |
| * All of these functions (wlanDrvIf_GetFile, drvMain_InitHw, drvMain_InitFw, drvMain_ConfigFw, |
| * drvMain_StopActivities, smeSm_start, smeSm_stop) are provided with a callback which |
| * they always call upon completion, even if they are completed in the original (SM) context. |
| * Since these callbacks are calling the SM, a simple mechanism is added to prevent |
| * recursion, by postponing the last event if the SM is still in the previous event's context. |
| * 2) In any case of unexpected event, the eStatus remains TI_NOK, leading to the FAILED state! |
| * FAILED state is also reached if any of the functions listed in note 1 returns TI_NOK. |
| * Note that if these functions detect a failure in another context, they may call their callback |
| * with the eStatus parameter set to TI_NOK, or call the drvMain_InitFailCb callback. |
| * All these cases lead to FAILED state which terminates all driver activities and wait for destroy. |
| * 3) Note that the wlanDrvIf_GetFile is always completed in the original context, and the |
| * option of completion in a later context is only for future use. |
| * 4) All processes (Start, Stop, Relcovery) are protected by a watchdog timer to let |
| * the user free the driver in case of deadlock during the process. |
