NVMe defines the host as following: "1.6.16 host An entity that interfaces to an NVM subsystem through one or more controllers and submits commands to Submission Queues and retrieves command completions from Completion Queues." in other words - the Linux kernel is the NVMe host. You need to describe this magic broken piece of crap a lot better than that. _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
