Hi, Ray
The meeting minutes of last Friday's TianoCore design meeting is listed below.
I am not sure how to send out the meeting minutes, send it to the community in mail or paste it in somewhere?

Thank you!

1. TDVF Design Overview v0.9

2. Propose 2 Configurations for TDVF to upstream (https://edk2.groups.io/g/devel/message/76367)
a. Config-A: (slide 6)
b. Config-B: (slide 8)

3. Discussion about the 2 Configurations
a. RTMR:
i. RTMR is not supported in Config-A. But we support QEMU based vTpm in Config-A.
b. PEI phase:
i. In Config-A, if PEI phase is skipped, then the QEMU based vTpm will not work.
ii. Intel need to figure out a way to fix this gap.
1. support vTpm in TdxStartuplib
2. or follow the standard EDK2 flow SEC -> PEI -> DXE ->BDS
c. Page table
i. 5-level page table is considered to be implemented in the future, but not a TDVF task in Config-A

4. The new design review session is booked at Jun 25 for further discussion.
