Yeah, the attached file mostly included Xeons because I couldn't find a
desktop or laptop CPU for each generation. However I did find Penryn and
Nehalem desktop CPUs and they already had vNMI support.
I stopped at Haswell because we still don't support nesting some
Broadwell+ extensions (e.g. PML). In fact we don't support EPT A/D
bits too, though that one shouldn't be hard to add.
The list of server-only features seems to be small though until Haswell:
only EPT 1GB page tables, PLE and APICv.
> 2. No Atoms in the list.
Centerton (Saltwell-based) is the only one I have access to and it's
the same as Conroe, so it has it.
