I am running kernel 2.6.21 on my realview_eb_mpcore system. at the beginning I found the program is stuck at calibrating loop................, this is because that the timer0 didn't give out any interrupt.
after enable the timer0's interrupt, I found that even when there is no timer interrupt the interrupt routine (realview_timer_interrupt() )is still reached. I added a timer interrupt disable instruction in the routine realview_timer_interrupt() , which makes sure that after the first interrupt the interrupt would be disabled. even in this situation , I can still see that the interrupt routine is accessed by the cpu. I guess this maybe caused by the problem of the gic_ack() or some other functions? does anyone ever meet such a situation? anyone knows how to handle this? any idea is appreciated. regards, Yang - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
