Maybe we can let TCG PEIM install the TCG_PPI *b= efore* any measurement record, then the other PEIM can register a callb= ack to record the HW ROT measurement ?

If we are resolving same problem, we can resolve al= together.

Since we’re working on early boot TCG interfa= ces, is this a good time to discuss a standard way to init the log with mea= surements made by the HW root of trust prior to Tcg2Pei? We were using a NU= LL lib and a registration pattern on the PEIM, but I’m open to other ideas, too. Thoughts?
