January 3, 20206 yr When I try to pass through a new serial controller it's not showing as an available option to passthrough on the VM. Here's the controller I'm trying to use https://amzn.to/37yXpUZ IOMMU group 22 [RESET] 08:00.0 Serial controller [0700]: MosChip Semiconductor Technology Ltd. MCS9922 PCIe Multi-I/O Controller [9710:9922] label Unraid OS menu default kernel /bzimage append vfio-pci.ids=8086:1521,8086:5912,9710:9922 initrd=/bzroot 8086:1521 and 8086:5912 are a graphics and nic card which pass through fine, but the serial controller doesn't show up. What am I doing wrong here? Edited January 3, 20206 yr by mlapaglia
January 3, 20206 yr Author Changing it from vfio-pci.ids to pci-stub.ids made it show up label Unraid OS menu default kernel /bzimage append vfio-pci.ids=8086:1521,8086:5912 pci-stub.ids=9710:9922 initrd=/bzroot Is stubbing a good solution? Is the server hooking onto the serial card before unraid can try to pass it through but stubbing is earlier in the process?
