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 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
