It's quite messy, "iommu" controls only GART, SWIOTLB and Calgary (IBM) while AMD-V and Intel VT-d have their own options. I couldn't find this in docs, but your kernel messages suggest that AMD-V disables GART and "iommu=soft" disables AMD-V. Generally, Intel systems with VT-d, and AMD systems with AMD-Vi support this. But it is not guaranteed that everything will work out of the box, due to bad hardware implementation and missing or low quality drivers.

Nov 25, 2015 · Enable IOMMU for AMD CPU; 1. Enable VT-d for Intel CPU. If you have an Intel CPU, the IOMMU technology is called "VT-d". If it is not already done, enable "Intel VT-x" virtualization feature. This is the virtualization technology that everyone knows. In the Asus UEFI BIOS, this feature is in "Advanced -> CPU configuration" and is named "Intel Virtualization Technology".
