[Qualcomm feedback] Chapter 5.1. Clarify deployment models with figures #52

Closed rsahita closed 6 months ago

rsahita commented 7 months ago

Reference: link

There are two deployment models possible here. CoVE ABI is equally applicable for both modes - this specification focusses on the second deployment model (b) where a peer supervisor domain is used to host confidential workloads.

This requires a bit of rewording I guess (b) is referring to (2) below. Also as mentioned before, other deployment models are possible that can house multiple TSMs.

A diagram depicting the architecture for variant 1 would be helpful, as it does not rely on SMMTT.

yes it was a, b in ascii doc and it got replaced as 1, 2 (since i had not used the lower alpha tag) - fixed that to use numbers. also will put a figure for deployment model 1 in appendix since that is not the focus of this spec per se.
