Hello Kun, Could you help to send the library interface together with its usage in modules in the series? Thanks in advance. Also, one more question is that are Tcg2Smm and VariableSmmRuntimeDxe the only modules need to be updated? Or an investigation in the code base should be done to address all the potential modules affected?

But if it is preferred to submit the patch for Tcg2Smm and VariableSmmRuntimeDxe to make better sense on how this interface will be consumed, I can send them out in v2. Please let me know how you would like to proceed. Thanks, Kun
