Is this chip something we will be able to obtain outside of China? Will hardware documentation be published in English, other than that provided by AMD for its not-quite-the-same-hardware? What plans does Hygon have going forward? Will they continue to just license future AMD designs or will there be any differentiation?
It seems that Hygon is just a licensed AMD Zen core with zero differentiation. Why not just set cpu_vendor_id to CPU_VENDOR_AMD if Hygon cpuid string is detected? That way we can avoid rototilling almost all of this code by treating hygon / family 0x18 as a weird AMD (which it is).
My concern is that this adds maintenance burden to the AMD MD codebase for an obscure chip no one actually has, uses, or has documentation for.
