Subject: [PATCH v1 0/3] SVM 5-level page table support
Date: Thu,  5 Aug 2021 15:55:01 -0500	[thread overview]
Message-ID: <20210805205504.2647362-1-wei.huang2@amd.com> (raw)

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
