Back in 2021 AMD began preparing Linux kernel support for 5-level paging support with their future processors and building off the prior 5-level page table kernel support established by Intel. That was followed by AMD enabling 5-level page table support with KVM SVM in the Linux 5.15 kernel. AMD CPUs with 5-level page table support since launched in the form of 4th Gen EPYC "Genoa" processors. One piece only now coming together though is AMD IOMMU driver support for 5-level guest page table support...
