commit 2e6bcb2a4291f9ae66a4cd44ddec2375723fb1b8
Author: Dan Terpstra <terpstra@eecs.utk.edu>
Date: Thu May 2 14:19:43 2013 -0400
Add two command line switches:
-i EVENTSTR includes only events whose names contain EVENTSTR;
-x EVENTSTR excludes all events whose names contain EVENTSTR.
These two switches can be combined, but only one string per switch can be used.
This allows you to, for example, filter events by component name, or eliminate all uncore events on Sandy Bridge…
