oprofile: enabling cpu events

[li nux]

I want to profile cpu events using oprofile, when i
issue following command, it gives me an error saying
that oprofile is in timer mode.
What does it mean ?
the link
http://oprofile.sourceforge.net/docs/intel-piii-events.php3
says event=CPU_CLK_UNHALTED is suppported for Pentium
II processor.

Is there any way i can enable cpu events ?

# opcontrol --setup  --event=CPU_CLK_UNHALTED
You cannot specify any performance counter events
because OProfile is in timer mode.

#opcontrol --event=CPU_CLK_UNHALTED
You cannot specify any performance counter events
because OProfile is in timer mode.
