I putthe following rtdm_printk functions in this function and the
rtdm_printk("\tEvent occured\n");
never is doner when a send messages to the receiveing network.
I don't know why.
static void rt_stack_mgr_task(void *arg)
{
rtdm_event_t *mgr_event = &((struct rtnet_mgr *)arg)->event;
struct rtskb *rtskb;
rtdm_printk("\tArrive to the rt_stack_mgr_task function\n");
while (rtdm_event_wait(mgr_event) == 0) {
/* we are the only reader => no locking required */
rtdm_printk("\tEvent occured\n");
while ((rtskb = __rtskb_fifo_remove(&rx.fifo)))
{
rtdm_printk("\trtskb removed from fifo\n");
rt_stack_deliver(rtskb);
rtdm_printk("\trtskb delivered\n");
}
}
rtdm_printk("\tGoing out from rt_stack_mgr_task function\n");
}
The first
rtdm_printk("\tArrive to the rt_stack_mgr_task function\n");
and the last
rtdm_printk("\tGoing out from rt_stack_mgr_task function\n");
are done in the starting and at the end of rtnet.
Any clues??
