I apologize for not defining the acronyms, I had wrongly assumed they
were well understood by the reviewers/maintainers. I can fix that up
going forward. In the meantime:
RMP: Reverse Map Table
SEV: Secure Encrypted Virtualization
SNP: Secure Nested Paging
These definitions are also available in AMD-APM vol 2: Chapter 15 [1]
