AM5 IOMMU VFIO - Best Motherboard

Hardware Motherboards
, ,
1

It’s time to upgrade and looks like it’s the best time to do so.

I have anUnraid server that I use for plex and a couple of VM’s, but I will be using a windows 11 VM as my daily driver.

I’m looking at the new AMD 7000 series and I don’t know what motherboard is going to give me the best IOMMU separation, so passing through my GPU, USBs, storage, and possibly motherboard sound to my Windows 1 VM.

If anyone has tested their AM5 chipset motherboard, please send me your IOMMU screenshots. At least some advice on which brand to go with.

Also, if you have a great recommendation on a AM4 chipset motherboard that will have great IOMMU separation, please send that as well.

Another question:

Are the IOMMU grouping defined by purely the chipset?

Too early to know for B650. Also not sure if the B650/B650E difference may play into that.

@Patrick_Layton Asrock X570 Taichi motherboard has the best virtualization features in their BIOS. While I didn’t mess with graphic card pass-through due to the lack of having two graphic cards, using VirtualBox, I was able to create a few virtual machines inside a virtual machine. If I hadn’t ascendingly destroyed the computer’s power supply, I would still be using that system instead of my current one.

are you sure you don’t have the acs patch enabled in your kernel?

From what I can tell (I dont have many b650 mobos yet) the apu video/audio should be in one group, and chipset usb hubs should be grouped together as well.

If you’re looking for one to get from ASRock, the PG Riptide mATX is what I’m dying to know the IOMMU to. If it’s good, I’m gonna get it and wait for the Phoenix APU AM5 chips to start my homelab.

The Asus ProArt X670E-CREATOR WIFI is the MB I’m looking at for an upcoming build as it has the connectivity I’m looking for as far as PCIe slot layout, M.2s and USB4(which may or may not be Thunderbolt). So if anyone gets one of these and can dump the IOMMU groups that it would be much appreciated.

Vanilla Ubuntu 22.04 LTS install. Only updated and rebooted. 100% sure it’s the stock Ubuntu kernel.

Really wish I had a DDR5 ECC UDIMM to test with. I’m not willing to pay Dell $350 for a 16GB stick, ugh.

So that IOMMU dump is from the Asus ProArt X670E-CREATOR WIFI? Thanks!

11

Yeah that’s from the X670E-Creator. Finally managed to get one last Friday when they finally came in stock in the U.K. As you can see too it is thunderbolt.

12

What haben’s if you use a Thunderbolt to PCIe enclosure, do these cards get a own group or are they lumped together with other devices? - this wouldn‘t be very useful.

14

I’d imagine it stays in the same group, everything in group 20 I am guessing is chipset connected not entirely sure. An external graphics card or a need to pass through anything connected to the thunderbolt 4 ports is beyond my own use case and not something I’m looking to do.

15

After thinking of it more both will 100% be in group 20 still as they are also Display Port outs to be used with the integrated graphics on the 7000Series or if you use the Display Port input feature on the X670E-Creator.

16

It’s just a general question. I‘ve read that passed through PCIe devices on the thunderbolt port are available as separate devices while the host takes care about the thunderbolt controller. I just wanted to make sure before I blow 500 bucks on this that the groups are sorted.

17

That looks promising, thanks Blissing. Have you had any success passing through any pci cards besides the gpu? Looking to pass through a pci usb card and wondering if the small pci slot on the bottom of the board is in its own iommu group.

18

Not a card specifically but have passed a controller on the motherboard before. Passing a usb card shouldn’t be difficult as long as the IOMMU grouping is fine.

19

Isn’t group 20 problematic as:

You wouldn’t be able to pass these through, would you?

Trying to figure out a good AM5 board to do passthrough.
