Hi, as you noticed domain_page_flush is a big hammer and may seriously impact performance. I suppose that's a reason why VHPT size is reduced. It would be really better to only purge by range (like vcpu_ptc_ga). But can the mapping addresses be easily known ? What do you think about this issue ? Tristan. _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel |
