For what purpose? The length of the access doesn't affect which handler should accept the IO. This length check now causes an MMIO handler to not claim an access which straddles the upper boundary. It is probably fine to terminate such an access early, but it isn't fine to pass such a straddled access to the default ioreq server. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
