The global timer is a 64-bit free running up-counter and can generate 4 interrupts when the counter reaches one of the -four preset counter values. The CPU local timers are 32-bit free running +four preset counter values. The CPU local timers are 31-bit free running down-counters and generate an interrupt when the counter expires. There is one CPU local timer instantiated in MCT for every CPU in the system. -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
