This is the same signature we use for Icelake-Server, which is most likely wrong. The question is which one should be changed and to what value? But most likely the Icelake-Server signature is wrong. We copied it from QEMU, but I haven't seen a mention of any real Icelake-Server CPU with such signature (or perhaps at all). Anyway, it would be nice if we could add a test data (prior to this patch) from host with Snowridge CPU to prove its signature is correct. Jirka
