Xen tracks protected memory regions in its private e820 structure. If tboot is no longer marking E820_UNUSABLE in e820, then have Xen manually add the regions to its private e820. Then you won’t need your new ad hoc structure plus needing to process that new structure in various places. -- Keir On 20/01/2009 05:49, "Cihula, Joseph" <joseph.cihula@xxxxxxxxx> wrote: tboot no longer marks the TXT heap/SINIT/private config space as E820_UNUSABLE in the e820 table, so Xen must explicitly disallow those regions from dom0. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
