I think the prime issue is that dma_direct_alloc respects the dma mask. Which we don't need if actually using the iommu. This would be mostly harmless exept for the the SEV bit high in the address that makes the checks fail.
For now I'd say revert this commit for 4.17/4.18-rc and I'll look into addressing these issues properly. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
