The differences are substantial enough that pci-gart.c needs several functions that are only in lib/swiotlb.c. Is xen-merge going to move up to 2.6.16 soon or should I just figure out the Makefile magic to get x86_64 to compile with lib/swiotlb.c if CONFIG_IOMMU_GART is defined and arch/i386/kernel/swiotlb.c if it isn't? -Mark Langsdorf AMD, Inc. _______________________________________________ Xen-merge mailing list Xen-merge@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-merge |
