Hello Xenomai experts, I am running a xenomai-2.5.1 patched kernel (v 2.6.30.3) with ipipe version 2.7-06. The target is powerpc (MPC8533E). My application is switching to the secondary mode (I guess because of a page-fault) when ntohl() is called. This is a libc function and I am wondering why only this function (ntohl()) is causing a page-fault.
Here is how the application looks like main () { ... ... /* Avoids memory swapping for this program */ mlockall(MCL_CURRENT | MCL_FUTURE); ...... ...... /* signal handlers */ ..... ..... /* create communication pipes */ rt_pipe_create(&tPipe1, ..... rt_pipe_create(&tPipe2,....... /* create RT tasks */ rt_task_create(&tTask1,..... rt_task_create(&tTask2,...... ........... .......... /* start the RT tasks */ rt_task_start(&tTask1,..... .............. .............. /* turn the current thread into RT function */ ret = rt_task_shadow(NULL, "RT main function", 1, T_SUSP); .... .... } One of the rt tasks created calls ntohl() and switches to secondary mode. Is there a way to avoid it ? -- Thanks and regards Bharath
