[Qualcomm feedback] Chapter 4: Clarification on usage of Smmtt #45

Closed rsahita closed 6 months ago

rsahita commented 7 months ago

Reference: link

For Supervisor Domain memory isolation, the Smmtt extension may be used for deployment scenarios where the TSM is at the same privilege level as the VMM.

Not sure we understand the significance of this qualification

rsahita commented 6 months ago

this is simply stating that a TSM operating in a separate supervisor domain, operates at the same privilege mode as the VMM in the hosting supervisor domain.
