Our automated tests still use 2.6.32. It wouldn't surprise me if upstream Linux 3 doesn't have the pirq_eoi_map stuff; it's an optimisation rather than core absolutely-required functionality. It's the dom0 PV kernel that matters in this case by the way, not the kernel that you are running in HVM mode as a domU. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
