Could > it also apply an offset? No. ia64_get_itc() does no scaling it returns the raw value from the cr.itc register which increments at a frequency that the OS discovers using a PAL call. I'm not quite sure what the above code thinks it is doing. NS_PER_TICK may have been poorly named??? -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
