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 _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@lists.xensource.com http://lists.xensource.com/xen-ia64-devel
