It shouldn't be. I'm not sure if Ryzen has anything equivalent to the Intel Management Engine. Intel has been scrambling to patching the firmware for that (which basically gives a hardware-level rootkit to anybody who exploits it). The official docs just mentioned adding support for additional processors with an AGESA update. I wouldn't be surprised if at some point the motherboard vendors slip in the microcode updates there as well. When I was having issues getting linux to update the microcode I figured I'd check the firmware for updates. When it failed to boot I just rolled it back. They actually did 2 firmware releases, with one being used as a bridge to the other. That also makes me wonder if there is a microcode update of some kind in there. -- Rich
