Indeed there's nothing like this as of today. We talked about it in the
past but it's not very easy to implement on Linux (see below) so we
forgot about it until somebody complained.
Adding infos would certainly be fine. I think it should rather be
"CPUType" and "CPUModel" since existing infos have no underscore in
their name if I remember correctly. You could also set object->name to a
combination of type and model. Socket looks like the right object to put
this. Maybe even use "Model" and "Type" as the info names then?
The reason it's not easy on Linux is that we usually take infos from
either sysfs, or /proc/cpuinfo if sysfs isn't available, but not from
both. Processor names are only in /proc/cpuinfo IIRC. So we'd need to
mix sysfs and /proc/cpuinfo. Not easy with the current code, especially
if you can't assume that all sockets are similar. But definitely
something that I will do at some point.
