Yes, but it by no means covers all zen 2 models. See amd-ucode/README Family=0x17 Model=0x31 Stepping=0x00: Patch=0x0830107a Length=3200 bytes Family=0x17 Model=0xa0 Stepping=0x00: Patch=0x08a00008 Length=3200 bytes 17-31-00 Rome/Castle Peak 0x0830107a 17-a0-00 Mendocino 0x08a00008 Models missing include: 17-60-01 Renoir 0x0860010b 17-68-01 Lucienne 0x08608105 17-71-00 Matisse 0x08701032 17-90-02 Van Gogh The known good patch levels are used by xen and linux.
