Hi Thomas, here comes V2 of the patch to add sched_clock to the Atmel TCB clock source. It provides the sched_clock: 32 bits at 16MHz, resolution 60ns, wraps every 260301047747ns It is not yet clear, why interrupts are enabled when this code is running. Thanks, -Carsten. -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
