If Confidential Computing (Cc) firmware supports measurement and an event is created, CC-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 CC-Guest firmware supports measurement. It is designed to produce EFI_CC_MEASUREMENT_PROTOCOL with new GUID EFI_CC_MEASUREMENT_PROTOCOL_GUID to report event log and provides hash capability. Patch #1: Introduce the CC Measurement Protocol definition into MdePkg. Patch #2: Update DxeTpm2MeasureBootLib to support CC based measure boot. Patch #3: Update DxeTpmMeasurementLib to support CC based measurement. Code is at https://github.com/mxu9/edk2/tree/td_protocol.v4 v4 changes: - Rename TeeMeasurementProtocol to CcMeasurementProtocol based on the discussion in below links: https://edk2.groups.io/g/devel/message/82876 https://edk2.groups.io/g/devel/message/82999 https://edk2.groups.io/g/devel/message/83000 With this protocol, CC based measure boot is supported. TD based measure boot is one of the CC based measure boot. - The spec will be updated according to the changes later. - TdProtocol.h is deleted. Its content is merged into CcMeasurement.h. - Add gEfiCcFinalEventsTableGuid definition in MdePkg.dec - Update the description in DxeTpm2MeasureBootLib.inf and DxeTpmMeasurementLib.inf v3 changes: - Rename TdProtocol to TeeMeasurementProtocol which is a neutral name. With this protocol, TEE based measure boot is supported. TD based measure boot is one of the TEE based measure boot. - The spec will be updated according to the changes later. - Fix errors in DxeTpm2MeasureBootLib. 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.
