Stefano, can you take a look asap? This is a pretty trivial fix for a nasty bug that breaks boot on real life systems. I'd like to merge it by tomorrow so that I can send it off to Linus for the next rc (I will be offline for about two days after Friday morning) ___ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu

Unfortunately AOSP is giving me grief this week, so I've not been able to test the full environment, but I don't seem to be hitting the io hangs I was seeing earlier with this patch set.

This looks good modulo the minor nitpicks. Konrad, are you ok with me picking up both through the dma-mapping tree? ___ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
[PATCH 0/2] SWIOTLB fixes for 4.20
This is what I have so far, which at least resolves the most ovbious problems. I still haven't got very far with the USB corruption issue I see on Juno with -rc1, but I'm yet to confirm whether that's actually attributable to the SWIOTLB changes or something else entirely.
