If TEE-Guest firmware supports measurement and an event is created,
TEE-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 TEE-Guest firmware supports measurement. It is
designed to produce EFI_TEE_MEASUREMENT_PROTOCOL with new
GUID EFI_TEE_MEASUREMENT_PROTOCOL_GUID to report event log
and provides hash capability.
Patch #1:
Introduce the TEE Measurement Protocol definition into MdePkg.
Patch #2:
Update DxeTpm2MeasureBootLib to support TEE based measure boot.
Patch #3:
Update DxeTpmMeasurementLib to support TEE based measurement.
Code is at https://github.com/mxu9/edk2/tree/td_protocol.v3
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.
