Device Security doesn't mention that IOMMU Protection is also called "Intel Virtualization Technology for Direct I/O (Intel VT-d)" and "AMD I/O Virtualization Technology"
"Intel Virtualization Technology for Direct I/O [Intel VT-d] is an I/O memory management unit (IOMMU) designed for the VMM (Virtual Machine Monitor), to support I/O virtualization. Since Intel VT-d has the capability of fine-grained access control per device, it is a better mitigation for DMA attacks."
I was confused, searching for this option in the UEFI Settings and searching about why my laptop supposedly didn't have it, until I found out that it does have.
Additional information
- GNOME/GNOME Settings 43.1
