Please introduce a command line parameter to control this, but defaulting to read-only is perfectly fine. I can well imagine that there are some bits of firmware around which reuse the other 3/4 of the HPET page, and users with such hardware will need a workaround. Perhaps a boolean parameter named "ro_hpet" ? ~Andrew _______________________________________________ Xen-devel mailing list [email protected] http://lists.xen.org/xen-devel
