[PATCH v1 0/3] SVM 5-level page table support

From: Wei Huang
Date: Thu Aug 05 2021 - 16:55:16 EST


This patch set adds 5-level page table support for AMD SVM. When the
5-level page table is enabled on host OS, the nested page table for guest
VMs will use the same format as host OS (i.e. 5-level NPT). These patches
were tested with various combination of different settings (nested/regular
VMs, AMD64/i686 kernels, etc.)

Thanks,
-Wei
