I would like to use oprofile to measure P4 FSB activity.  The P4 architecture does support counters for that.  The FSB_DATA_ACTIVITY event is listed in /usr/local/share/oprofile/i386/p4/events.  It is simple to measure and doesn’t require any tagging.  Is it possible to use oprofile to measure FSB events?  If so, is there additional configuration that is needed.  I am using a recent version of oprofile checked out from CVS and kernel.org kernel version 2.6.14.  Thanks.
