I'm wondering if we could remove it. I've been done lots of maintainance on various dma mapping and iommu drivers, and the calgary one seems like it didn't get a whole lot of love, and I've not seen any recent users, so I mostly wonder if I should bother at all. _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
