Can this package support detecting CPU microarchitecture information?

The sample output gives a good overview. Would CPU Family, Model, and microarchitectue level be enough or are you looking for something else?

Yeah, we just need to find a cpuid alternative golang pkg/lib to achieve similar target, since cpuid itself is a binary dependency which is not included in all Linux Distros. Another reason is that the command call in Golang is also not so elegant.

We found project here, but the current CPU mapping list looks not complete. Not sure if there is any project where the CPU mapping list is well maintained and up-to-date, at lease for Intel CPUs:)

There is none here. I cannot commit to maintaining such a list, but I would accept a reasonably worked through PR that can map family+model to a microarch.

The cpuid_data.zip can be used for testing.
