Create a Documentation entry to describe the AMD Secure Encrypted
Virtualization (SEV) feature.
A couple of quick notes...
- This is describing an x86 subarchitecture feature, so it seems to me
that Documentation/x86 would be a more logical place for it. Yes, KVM
can use this feature, but it's not a KVM feature and there might be
something else that takes advantage of it too.
In part1 of SEV patches, we do expand the
Documentation/x86/amd-memory-eencryption.txt to explain the SEV
architecture feature. In this patch, we focus on documenting the SEV
specific changes from the KVM point of view and how it integrate with KVM.
- Any chance of getting it formatted as RST? It's almost there already.
Sure, next rev I will convert it to RST format.
Beyond that, the document obviously falls far short of what one would
have to know to use SEV; probably filling all that in would make it long
indeed.
In later part of patches (Patch 24/38 [1]), I expand this doc to provide
high level overview of various SEV commands to support common lifecycle
events of SEV guests, such as launching, running, snapshotting,
migrating etc.
