Ok. I guess I don't have too strong of an opinion here. >> How / where do these new devices show up in the tree that is returned from >> hwloc?

Brice's text of "They have no cpusets / may appear at random places in the topology" could be interpreted multiple ways, so I wasn't sure. >> Is libpci available on all platforms?

Or do we allow building without it (and therefore you just don't get the PCI functionality)? -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
