The following "A Tour Beyond BIOS" whitepapers, available at https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-white-papers discuss the WSMT ACPI table: - "Secure SMM Communication" - "Memory Protection in UEFI BIOS" - "Memory Map and Practices in UEFI BIOS" With time, OVMF should install the WSMT ACPI table. I made an effort to analyze what was missing for that, here: [edk2-devel] WSMT bits 3c32815c-3ee9-261a-b473-1be341bdfb0c@redhat.com">http://mid.mail-archive.com/3c32815c-3ee9-261a-b473-1be341bdfb0c@redhat.com https://edk2.groups.io/g/devel/message/55715 The part (or, well, "one part") that OVMF seems to miss is Assumption/Recommendation #3 from "Secure SMM Communication", so this series supplies that. This series overlaps with TianoCore#386 (although the series is motivated differently from the BZ). I used TianoCore#386 as the BZ reference in the patches, for simplicity.
