The properties table should not be used. It has been superseded by the memory attributes table, per spec. In edk2, the properties table is controlled by the PCD, regardless of the memory attributes table. In edk2, the memory attributes table is always produced, regardless of the properties table. Please see the discussion under: [edk2] [patch 0/7] Add UEFI2.6 MemoryAttributesTable support. http://mid.mail-archive.com/1454069539-4056-1-git-send-email-jiewen.yao@intel.com Thanks Laszlo -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
