--- Comment #1 from Hiren Panchasara <hiren at FreeBSD.org> ---
On -HEAD (r278050M), I do see non-kernel events.
# pmcstat -S instructions -O /var/tmp/sample
# pmcstat -R /var/tmp/sample -G /var/tmp/sample.callgraph
In sample.callgraph, I see things like

100.0% [1] 0xdb799d @ /usr/local/lib/firefox/libxul.so

Am I understanding this correctly?
