Opreport can generate samples per function (usilg -l option).
In the paper you mentioned we grouped the kernel functions into classes using
scripts that maps functions into files and/or directories based on the
information in linux source tree.
This is a post processing step that you need to do to group functions into
meaninfull categories

Subject: [Xen-devel] questions about xenoprof
In the intial paper, "diagnosing performance overheads in xen virtual
machine environment", the author has published results about cache miss of
functions and their modules {xen, network driver and vmlinux} in table 1.
However, although I have tried very hard, I still can''t get the which
function belongs to which module in the "opreport". If I
can''t get the module information, how could I know which part of cache
miss belongs to virtual machines not the VMM or host?
Thank you!
