Thanks, if ACPI_HPET_PAGE_PROTECT4 is set then we can prevent access to the full page and if ACPI_HPET_PAGE_PROTECT64 is set we can prevent access to this page and the adjacent 60KB (15 pages). Will send an updated version. Roger. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
