counter register in-CPU. This is to be used as a fast "timer", where linearity is more important than time, and multiple lines in the linearity caused by multiple CPUs in an SMP machine is not a problem. This adds no code whatsoever to the FreeBSD kernel until it is actually used, and then as a single-instruction inline routine (except for the 80386 and 80486 where it is some more inline code around nanotime(9).
