March 19, 20188 yr Hello, I have been working for a few days now trying to get the GPU passthrough to work on my Dell R610. I have tried ACS override as well as the interrupts. My dmesg has the following lines and this is why I have tried the allow unsafe interrupts in my syslinux file. However, whenever I have that line, when I try to start or create a VM using passthrough, the VM portion of Unraid freezes and I cannot do anything including loading the VM page or the VM settings. Any help would be greatly appreciated as I have googled for days without much luck. [ 881.242312] vfio_iommu_type1_attach_group: No interrupt remapping support. Use the module param "allow_unsafe_interrupts" to enable VFIO IOMMU support on this platform [ 881.541863] vfio-pci 0000:07:00.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=none IOMMU group 15: [1b21:1184] 05:03.0 PCI bridge: ASMedia Technology Inc.
