What are the rules of RMIDs, I can't seem to find that in the SDM and I think you're tagging cachelines with them. Which would mean that in order to (re) use them you need a complete cache (L3) wipe. Without a wipe you keep having stale entries of the former user and no clear indication on when your numbers are any good. Also, is there any sane way of shooting down the entire L3? _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/containers
