This only enables it to be an option, it doesn't change things unless "enable_unsafe_noiommu_mode" is set. See this reference: https://patchwork.kernel.org/patch/7906971/ for more details. This is used for some setups of DPDK see this http://dpdk- guide.gitlab.io/dpdk-guide/setup/binding.html#vfio-no-iommu Usually the reason to pick vfio over uio is the isolation. But there are some cases where vfio is required for extra features but can't work unless NO-IOMMU mode is used. I watched the topic a while checking if there is some major "oh crap what have we done" but there was none. An since by only enabling it in the kernel it shouldn't change a lot I wanted to ask if you could enable this config in the kernel for Z*. Technically it would be nice to get it in Yakkety as well, but I think we should be fine only working forward and enabling it in the Z release.
