Using the common swiotlb code (as far as possible) for x86/64 may make sense -- many of the nasty differences in our own swiotlb implementation are to deal with CONFIG_HIGHMEM which does not exist on x86/64. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
