BTW, was there any progress on conditioning sev.c build on
CONFIG_KVM_AMD_SEV? (So that the defines workaround isn't needeed.)
Tom, Brijesh,
Is this something you guys thought about or have some plans to do in the
future? Basically to not include sev.c in compilation if
CONFIG_KVM_AMD_SEV is disabled.
It's crossed my mind, but the number of stubs needed made me back off. I'm
certainly not opposed to the idea, it's just not a trivial change.
Right, I looked at it when I was doing the SEV-ES work and came to the
same conclusion.
Thanks,
Tom
