In order to use mediated device functionality you may need to set some or all of the following settings in your machine's UEFI.
UEFI Setup
Intel CPUs (VT-d)
Optimal UEFI Settings
IOMMU >> Enabled
SR-IOV Support >> Enabled
VT-x >> Enabled
ARI Mode >> Enabled
AMD CPUs (AMD-v)
Optimal UEFI Settings
SVM Mode >> Enabled
SR-IOV Support >> Enabled
ACS Enable >> Enabled
IOMMU >> Enabled
PCI AER Support >> Enabled
ACS Enable >> Enabled
ARI Mode >> Enabled
Note to AMD CPU users: If you are using a first generation Ryzen or ThreadRipper platform you may need to update your motherboard UEFI to make proper use of IOMMU Groups. If your motherboard manufacturer has not made an update available you may need to apply an ACS override patch. Successive AMD CPU platforms are unaffected.
