Finishing the VHPT is on the "to do" list that I posted on xen-devel on Dec20. I put in some basic structure but decided to focus on base functionality rather than performance for the alpha release. I believe that not only is the code missing for inserting an entry, but also for soft-walking the LVHPT if the hardware walker misses. Since this is probably a huge performance impact, it would be a valuable contribution to add this code if you are interested. There was a Linux/ia64 patch to support LVHPT posted to the linux-ia64 mailing list a few months ago (from Australia if I recall) and I was going to look at that to see if there was code that could be leveraged/reused. I also have some code from a previous project that I was going to dig up. If you decide to work on this, please keep in touch so that effort is not duplicated.
