Hi Joerg,
I've got a little question on the amd_iommu code, hope you (or someone else on the list) can answer it. Most of the dma_map_ops methods have a fallback for the case when get_domain() return -EINVAL, which basically duplicates the normal no-iommu implementation, with the map_sg method being and exception that always returns and error (return value of 0 is an error for its calling convention). Is that an oversight? If yes so I wonder why it hasn't been caught yet. Or is the whole fallback code dead and can be removed? _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
