Am I screwed if both my GPUs are in the same IOMMU group? (Aorus X570 Master)

Operating Systems & Open Source Linux
4

Please enable these options in BIOS and report back with your full IOMMU groups list

SVM → Enable
iommu → Enable
ACS Enable → Enable
Enable AER cap → Enable
Alternative routing → Enable

Not sure whether the Alternative Routing one is necessary. Please try enable/disable it and see if there is any difference.
