I too had the same intuition that DTrace works completely in software, but
after knowing that there is Performance Monitoring Unit(PMU) present in intel's
chip, so I got confused if DTRace uses it, also same type of hardware is

Need conformation.
Well, it uses the features of the CPUs it runs on, like breakpoint
instructions, traps, etc., but it's not *special* hardware of any sort;
it's just the standard hardware you get with your computer.
