Hey silly question did you turn on IOMMU in the vendor BIOS? by
default it is off.
This is caused by a bad driver or bad hardware, I had a old graphics
card that did the same.
My D16 works fine and I am able to assign a variety of devices to VM's
with vfio, I doubt this is a coreboot issue.
Yes, I turned it on and everything works fine. I use it to passthrough
my graphics card to my virtual machine.
Hmm...strange. I have no idea as to why this is happening. Thanks for
bringing this up btw, I was about to buy one for my VM gaming setup.
My guess is that it is related to the fact that ASUS's PCI-e audio cards
use a PCI audio chip, and thus require a PCI-e>PCI bridge. I hope they
release some native PCI-e audio cards soon.
Shot in the dark - but can you post your lspci -vv and IOMMU groups from
both the vendor bios and coreboot?
