RE: [Xen-devel] questions about xenoprof

["Santos, Jose Renato G" <joserenato.santos@xxxxxx>]

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!
