Date: Fri, 21 Apr 2023 16:36:17 +0800 [thread overview]
Message-ID: <20230421083628.1408-1-dun.tan@intel.com> (raw)
In V3 patch set:
1.Add a new patch 'Remove code that apply AddressEncMask to non-leaf entry'.
This patch is to avoid apply AddressEncMask to non-leaf entry when split smm page table.
2.Add two new patches to clear CR0.WP before modify smm page table when ReadyToLock.
This is because FvbServicesSmm driver may set a part of smm page table memory as RO before ReadyToLock.
With these three patches, this patch set successfully boots an SEV guest with SMM enabled.
