Now that the EDK2 tree uses GetMemoryProtectionsLib to query the platform memory protection settings, OvmfPkg can be updated to use QemuCfg to set the entire memory protection profile instead of just SetNxForStack. For example, the following will set the DXE memory protection to the RELEASE preset. -fw_cfg name=opt/org.tianocore/DxeMemoryProtectionProfile,string=release The following will set the MM memory protection to the RELEASE preset. -fw_cfg name=opt/org.tianocore/MmMemoryProtectionProfile,string=release For users of Stuart, DXE_MEMORY_PROTECTION_PROFILE=release and MM_MEMORY_PROTECTION_PROFILE=release are equivalent to the above examples.
