I'll start working on this approach.This also facilitates a useful follow-on change: modify XS_INTRODUCE totake a grant reference instead of an mfn and use that as the command (instead of XS_NEW_CONNECTION) to establish communication with the userspace clients. This would have the additional benefit of not requiring xenstored's domain to be privileged just to map pages for its clients. Of course, it would mean altering the domain builder code to create a grant reference for the xenbus page. We definitely want that change anyway (and also for the console page). We already reserve the first 8 entries in every grant table to allow us to implement this in future. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
