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 ?
