Theory: If some BIOS programmer set aside two records to be used for various needs, and then on boot detected that one of them wasn't needed (say, integrated graphics not present, so 0 MB reserved?), perhaps said BIOS programmer would just set the range to be 0 bytes, rather than go through the effort to remove the entire record? What could go wrong if the parser just treated entries mapping 0 byte ranges (like this one) as if they didn't exist? -- View this message in context: http://www.nabble.com/VT-D-RMRR-is-incorrect-tp22005500p22423800.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
