In normal boot mode, the screen shows a single line :

get_cyclecount
GET_CYCLECOUNT(9) BSD Kernel Developer's Manual GET_CYCLECOUNT(9)
NAME
get_cyclecount -- get the CPU's fast counter register contents
SYNOPSIS
#include <sys/param.h>
#include <sys/systm.h>
#include <machine/cpu.h>
u_int64_t
get_cyclecount(void);
DESCRIPTION
The get_cyclecount() function uses a register available in most modern CPUs to return a value that is monotonically increasing inside each
CPU.
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.
The speed and the maximum value of each counter is CPU-dependent. Some CPUs (such as the Intel 80486) do not have such a register, so
get_cyclecount() on these platforms returns the number of nanoseconds represented by the structure returned by nanotime(9).
The Pentium processors all use the TSC register.
The Alpha processors use the PCC register.
The IA64 processors use the AR.ITC register.
SEE ALSO
nanotime(9)
HISTORY
The get_cyclecount() function first appeared in FreeBSD 5.0.
