Actually I think I ran into this once before. Someone sent me a screen shot of their e820 mappings from the actual BIOS setup program clearly showing the memory range was reserved yet the check that generated the message below was triggered. I could not reproduce it but I think I tracked it down to changes that xen was making to the e820 mappings in sanitize_e820_map() (that is IIRC, it was a year ago or more).

Actually iommu_inclusive_mapping=1 is the default now. The above warning appears to print even when iommu_inclusive_mapping is set. :-) -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
