Do we really need to duplicate the swiotlb code? Did you need to make big changes? Other points that I can see from a quick browse include the fact that alloc_coherent() still looks broken afaics and the one-liner in io_apic-xen.c is a bit random (since none of the other use-iommu-or-not decision points are changed, and the GART stuff which is presumably what is being kludged around is not even included in Xen builds yet). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
