AMD Zen 3 based Cezanne processors which are models 50-5fh are out in the market. We should add a few things for these:

To test this, I managed to track down a Cezanne system and verified the following:

  • The socket was detected as AM4 via fmtopo
  • fmtopo also showed the temperature sensors for the CPU cores, which implies that we had correctly attached the Zen nexus driver and found all the data fabric bits
