X570 taichi IOMMU groups

I fancied having a play with VFIO and upgrading my ancient 2500k, so bought an x570 taichi and a 3700x. Wendell’s video implied that the grouping was good on this motherboard, but I can only seem to get 9 groups, with NVMe drive mixed in amongst other devices, so I’m wondering if I’m doing something wrong?

Tried UEFI versions 1.60, 1.65 and 1.70, each with the same result.

Here’s the groupings:

It might be useful for people to start posting their IOMMU groups in general. Here are the results for my ASUS ROG Crosshair VIII Hero Wi-Fi (BIOS 0702) with 2 GPUs attached.

Overall I’m pretty happy with it (28 groups!) except none of the USB controllers are on their own IOMMU groups (I’ll either be seeing if I can set up dynamic attachment with udev, or maybe I’ll put in a PCIe controller vs ACS). I just went on my own VFIO journey yesterday (I’ll probably do a write-up soon as there were a lot of sharp edges I encountered and managed to (eventually) solve).

For the X570 Taichi go to
Advanced>AMD CBS>NBIO Common Options
Make sure you have “IOMMU” set to “Enable” (Auto doesn’t work).
Also make sure “Enable AER Cap.” is set to “Enable”
Once you’ve set that an option called “ACS Enable” will show up, I left that set to “Auto”.

After that’s done you’ll have the normal X570 IOMMU groupings.

Thanks so much, that worked! it would’ve taken me ages to discover that :smiley:

You ever have any luck passing through your HD Audio Controller? I have a very similar grouping (x570 TUF Gaming mobo) and while the GPU passthrough is working fine, the audio is giving me trouble. Seems to be paired up in a group with SATA controllers and some other stuff…

Thanks!

I also struggled with the audio controller for a while until the latest firmware, AGESA 1.0.0.4 Patch B
