I have been looking in Cortex-A9 MPCore doc, and have seen that it is routed to IRQ29. In arch/arm/mach-vexpress/include/mach/irqs.h I can see IRQ_LOCALTIMER defined, but I do not see it used anywhere. Is there some example of this timer usage I can look at and see what have to be done to set up this timer and associate irq, so that it is triggered each time the timer expires. BR, Drasko
