If TD-Guest firmware supports measurement and an event is created, TD-Guest firmware is designed to report the event log with the same data structure in TCG-Platform-Firmware-Profile specification with EFI_TCG2_EVENT_LOG_FORMAT_TCG_2 format. The TD-Guest firmware supports measurement, the TD Guest Firmware is designed to produce EFI_TD_PROTOCOL with new GUID EFI_TD_PROTOCOL_GUID to report event log and provides hash capability. https://software.intel.com/content/dam/develop/external/us/en/documents/ intel-tdx-guest-hypervisor-communication-interface-1.0-344426-002.pdf Section 4.3.2 includes the EFI_TD_PROTOCOL. Patch #1: Introduce the TD Protocol definition into MdePkg Patch #2: Update DxeTpm2MeasureBootLib to support TD based measure boot. Patch #3: Update DxeTpmMeasurementLib to support TD based measurement. Code is at https://github.com/mxu9/edk2/tree/td_protocol.v2 v2 changes: - TD based measure boot is implemented in DxeTpm2MeasureBootLib. This minimize the code changes. - TD based measurement is added. It is implemented in DxeTpmMeasurementLib. - Fix the typo in comments.
