Hello! Your Dell Latitude E5520 is running Windows, but you're using Debian 9 on a separate drive. You've modified GRUB and turned on iOMMU. When checking `/sys/groups/iommu_groups`, nothing appears listed. This usually means the iOMMU driver isn't properly detected or enabled. Try reinstalling iOMMU drivers or ensuring your BIOS supports them. If issues persist, consider updating your BIOS or consulting Dell support for compatibility.

Yes, a Dell Latitude is indeed a laptop. It uses a mobile CPU that supports VT-d, and many desktop models with i5 cores can also enable it. The motherboard must be compatible for this feature. As for the IOMMU, it’s important to understand its role in enhancing performance and security.
