But that's the purpose of iommu=force, no? With "iommu=force": strictly require IOMMU Without "iommu=force": use IOMMU on best-effort basis It makes sense to refuse the boot if intremap is broken in the first case. But also, it makes sense to allow using IOMMU without intremp in the second case. -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab
