Been pulling my hair out for an hour or 2 each day trying to get this working again. I’m trying to get GPU passthrough working again on Manjaro with 2 identical 1080TI’s. I had this working previously but something borked my Manjaro install so I had to reinstall from scratch, now I can’t seem to get it going again. I haven’t made any hardware changes in between so I know UEFI is setup correctly.
Following the steps from the Arch wiki (can’t post links here?)
But jumping from step 3 to 6.1 because of the identical GPUs. IOMMU is working but the 2nd GPU to be passed through is not using the vfio-pci driver which it would be if it were being properly passed through. Not really sure what I’m missing.
