        supported_frequencies_Hz        1000000000

And the output of  "dtrace -l|grep cyclic-start" is as below:
bash-3.2# dtrace -l|grep cyclic-start
 5125        sdt           genunix                    cyclic_softint 
cyclic-start
 5126        sdt           genunix                cyclic_remove_pend 
cyclic-start
 5127        sdt           genunix                     cyclic_expire 
cyclic-start

Thanks
