Thanks a lot for the input. I opened https://github.com/open-mpi/hwloc/issues/243 I have access to a T5 but this will need investigation to actually find where to get the info from. Feel free to comment the issue if you find more. I am going to modify Pg.pm to better understand where Caches come from.
