In case it helps, I booted with amd_iommu_dump=1 and got this:
[ 0.108593] [ T0] AMD-Vi: Using IVHD type 0x11

I'm also attaching the ACPI IVRS table.
Side note: I wanted to check AMD documents at https://docs.amd.com/
but the "Create Account" button doesn't work. :-(
(And why do they require an account anyway, Intel and ARM don't...)
Best Regards,
Johannes
