ARM's iommu code (arch/plat-omap/include/plat/iommu.h) is a library to simplify the IOMMU implementations. It could be useful for all the iommu implementations. The current iommu-api (include/linux/iommu.h) provides the common interface for specific purposes (for KVM). I think that the current iommu-api can be a part of the former. I also think that the IOMMU part of this new msm should be integrated into the former. Another question is how the above can work with the DMA-API. -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
