Hi all,

Please see my comments here, where I've linked to my gist
https://forum.level1techs.com/t/asus-rog-zenith-extreme-x399-threadripper-iommu-details/121122/7

-+-[0000:40]-+-00.0  Advanced Micro Devices, Inc. [AMD] Family 17h (Models 00h-0fh) Root Complex
| +-00.2 Advanced Micro Devices, Inc. [AMD] Device 1451
| +-01.0 Advanced Micro Devices, Inc. [AMD] Family 17h (Models 00h-0fh) PCIe Dummy Host Bridge
| +-01.1-[41]----00.0 Samsung Electronics Co Ltd NVMe SSD Controller SM961/PM961
| +-01.3-[42]----00.0 Aquantia Corp. AQC107 NBase-T/IEEE 802.3bz Ethernet Controller [AQtion]


The above do not appear in IOMMU groupings - Do I need to enable 'Enumerate all IOMMU in IVRs'?

Thanks! M.
