-.Dt GET_CYCLECOUNT 9
-.Os
-.Sh NAME
-.Nm get_cyclecount
-.Nd get the CPU's fast counter register contents
-.Sh SYNOPSIS
-.In sys/param.h
-.In machine/cpufunc.h
-.In machine/cpu.h
-.Ft u_int64_t
-.Fn get_cyclecount "void"
-.Sh DESCRIPTION
-The
-.Fn get_cyclecount
-function uses a register
-available in most modern CPUs
-to return a value
-that is monotonically increasing
-inside each CPU.
-.Pp
-On SMP systems,
-there will be a number of
-separate monotonic sequences,
-one for each CPU running.
-The value in the SMP case is
-selected from one of these sequences,
-dependent on which CPU
-was scheduled to service the request.
-.Pp
-The speed and the maximum value
-of each counter
-is CPU-dependent.
-Some CPUs
-(such as the
-.Tn Intel
-80386 and 80486)
-do not have such a register,
-so
-.Fn get_cyclecount
-on these platforms
-returns the number of nanoseconds
-represented by the
-structure returned by
-.Xr nanotime 9 .
-.Pp
-The
-.Tn Pentium
-processors all use the
-.Li TSC
-register.
-.Pp
-The
-.Tn Alpha
-processors use the
-.Li PCC
-register.
-.Pp
-The
-.Tn IA64
-processors use the
-.Li AR.ITC
-register.
-.Sh SEE ALSO
-.Xr nanotime 9
-.Sh HISTORY
-The
-.Fn get_cyclecount
-function first appeared in
-.Fx 5.0 .
-.Sh AUTHORS
-This manual page was written by
