Hi Robin,

Thanks for your work. We are really moving forward to a common DMA-API
implementation for all iommu drivers.

Yes, this would be great. I think it makes a lot of sense to make use of
the default domain feature. Can you have a look at how well this
integrates with my current patches for default domains and provide some
feedback?

Thanks,
