AM5 IOMMU VFIO - Best Motherboard

Re: ASRock X670E Taichi’s SATA ports: I bought some random used SATA drives off eBay to plug into the motherboard for verification. (I decided it was not worth the wait to see the 16 TB SATA drives go down in price. They are still too expensive at $1,700 a pop.) Here is what it looks like after connecting all the motherboard SATA ports (SATA drives marked by blue vertical bar):

Yes… my script also “cds” into PCIe devices and lses their USB or storage devices. I needed it to be able to easily identify which PCIe device was for what. I will publish my IOMMU script after some clean-up.

TLDR: So if you or anyone else reading this can confirm if it is possible to have basically each PCIe x16 slot on the ASUS B650 Creator board or any other AM5 board in its own isolated group that would be great.

Hi quilt. I have been researching into the ASUS ProArt B650 Creator and I think I am trying to create a similar setup to yours. I saw your IOMMU groups on the “ASUS ProArt X670E-Creator ACS in BIOS?” thread, and I am wondering if you could clarify something. I figured it would be best to ask here as others might find it helpful for others trying to research something similar.

My end goal is to passthrough:

  • A GPU to one VM (GPU is x16 card)
  • A HBA card to another VM (HBA is x8 card)
  • A few Intel Ethernet ports from a Intel I350-T4V2 to multiple VMs (NIC is x4 card)

The ASUS ProArt B650 Creator’s x8/x8 for PCIEX16_1 and PCIEX16_2 is where the GPU and HBA cards will go respectively. There should be no issue with the GPU running in x8 mode for my use case, but my primary fear and concern is this:

Both PCIEX16_1 and PCIEX16_2 will/might be in the same IOMMU group and therefore can’t be split between the VM that needs the GPU and the VM that needs the HBA card

My understanding is that IF the board supports ACS then there is more granular control over splitting the groups. But I can’t say for 100% certainty. I got most of this info from a 4yr old Proxmox reddit post called " How important is ACS, If I’m doing PCI pass through do I need to worry? E3-1285 V4".

The NIC card will go into the last PCIe x16 slot (PCIEX16_3) as it only runs in x4 mode and it runs off the chipset and not the CPU. So “should” be in its own group.

Any help or insight from anyone would be appreciated.

I can’t comment on the B650, but some here on the forum have it and have posted IOMMU groups.

That said, on my board both x8 slots from the CPU have their own groups. This should be the case for all AM5 boards since these are the CPU lanes.

Perfect. Thank you for the reply.

That iommu grouping on the Steel Legend is a bit disappointing to see.
i was actually interested in getting one.
Because i like the amount of usb ports and the dual nic´s.

Curious if anybody with this particular board and the newest bios updates if there,
are some improvements on the iommu situation or not?

Don’t know what you expect to see. The problem all AM5 boards have, is the second chipset, where all devices, and there are lots, are under the same IOMMU group. Below are from the GB Aorus Master:

Yeah that is a little bit of a bummer but it seems like the case with many X670E boards,
not having that great iommu groupings.

Thanks. :slight_smile:

ASRock Taichi X670E with BIOS version 2.00 has broken IOMMU groups.

I’ve edited the below to remove some devices from my script’s output. But having 7 groups now broke everything. :face_holding_back_tears:

That is a bummer really.

I kinda get the idea that X670E is not really that ideal for this in general.
Not sure how B650 (E) boards are doing.

71

The B650 boards seem to not have this issue. Which makes sense, since they have a single chipset, where x670 is literally two B650 daisy chained to the CPU.

It’s a bit sad, but it is what it is. Perhaps the next gen will be better. Having a pcie 5 link to the chipset would be nice too for 10GB nics and multiple ssd’s hanging on the chipset. Intel seems to do better in this respect, with an x8 link to the chipset.

72

Now this is fixed in ASRock Taichi X670E BIOS version 2.0.2.

The biggest bummer is the lack of documentation. These updates do f**k-what, and you wouldn’t know from the single sentence they write about it next to the download link.

No, it “improves performance for various devices”.
What’s vague about that?

74

No hint of unrelated changes to IOMMU groups

75

These are phenomenal groups on the B650 LiveMixer!

But wait, how come your B650 board has IOMMU groupings superior to some (or most) X670 boards here? Didn’t Wendell say that B650 and B550 are not suited for VFIO?

It seems to be a consequence of the daisy chained chipset on x670. Everything on the second chipset gets thrown in the same group AFAIK.

X670 is literally two b650 chained together with a pcie link.

77

Yeah, apparently.

I’ve been looking at the B650 MSI Tomahawk. Would anyone happen to have any knowledge of the IOMMU groups on that board?

Seems to me that ~ $200 B650 boards all seem to have very similar groupings, which are perfect like Asrock LiveMixer’s.

B650M PRO RS - Groupings with BIOS 2.02

I believe Group 9 contains some chipset connectivity. This is broken up after enabling some IOMMU related options in the BIOS. I will update this post after enabling said options.

From reading this thread, it’s seems that the AM5 boards with the “best” IOMMU groups are:

  • Asus ProArt B650-Creator
  • Asrock B650E Taichi (non lite)

Or did I miss something?
(Also eager to see what @tommy_goodshoes finds with the Pro RS board)

I almost pulled the trigger on a ProArt X670E board this week, but figured this was the place to confirm. Glad I came here first to check. :wink:

Thanks to those who are contributing to this topic!

Did anyone successfully pass-through the APU on Zen 4? I have a B650-Creator here with Ryzen 9 and as soon as I start a VM in proxmox, the system spontaneously reboots.

The other time this happened †o me was when there were other crucial devices in the IOMMU group, but the GPU has own dedicated one, so this shouldn’t be an issue?

amdgpu is blacklisted, device ID assigned to vfio module. Don’t know what else can I check?

It might be the wrong lead, but also check the usb devices if you passthrough an onboard AMD USB-controller along the iGPU.

I experience the spontaneous reboots you describe because the USB controller / host OS hates passing along a certain external USB-Hub in my case.

For AMD GPUs I also noticed that you may have to add the GPU device and the accompanying audio device as separate entries in your VM config and that the „pass all functions“ option of most hypervisors/VM management tools is not enough.
