I am not very happy with that patch, but I have a hard time coming up with something saner. Bascially x86_64 and mips/loongson default to SWIOTLB=y but allow to deselect it, powerpc has it optional without any real dependency and defaults to n and everyone just selects it otherwise. I suspect the right thing is to just have it always one for x86_64 and loongson and have a ppc-specific option to enable it on powerpc so that we can always use select statements. I'll do that for the next round. ___ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu

We shouldn't end up with NEED_SG_DMA_LENGTH=y on ARM by default. It is only select by ARM_DMA_USE_IOMMU before the patch, and it will now also be selected by SWIOTLB, which for arm is never used or seleted directly by anything but xen-swiotlb. Then again looking at the series there shouldn't be any need to even select NEED_SG_DMA_LENGTH for swiotlb, as we'll never merge segments, so I'll fix that up. ___ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu

For example, arch/arm/mach-rpc/dma.c doesn't use the dma_length member of struct scatterlist. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 8.8Mbps down 630kbps up According to speedtest.net: 8.21Mbps down 510kbps up ___ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
