I am looking to buy a new mini PC home server and I want to be able to pass through my iGPU and NIC to different VMs. Where can I find a well-maintained database of IOMMU groups so that I can pick a good match for my needs?

There exists iommu.info but that barely has any entries.

      There are links to other wikis with lists of devices.

      Thanks but these are only lists of CPUs and motherboards that support IOMMU, not the IOMMU groups. For me (and many others) the groupings are just as important as whether there is support at all.

      The groupings are defined by the motherboard. In my experience, all motherboards that support IOMMU will put at least 1 PCIe slot in its own own group, which is good for Graphics Card passthrough. However, the grouping of other stuff like SATA controllers and NICs varies wildly between board, and that is what I am interested in.
