If anybody has an EPYC[1], SuSe has a srpm - but it doesn't apply to
Ryzens, and the kerneli might need a patch because it had known
nothing about Ryzen microcode and tests against an old default size
(not sure which versions have that patch) - details at
https://bugs.archlinux.org/task/56951
Clearly this is aimed at Spectre.
I saw the kernel patch a while ago, which is why I was hopeful about
microcode. But I don't even have a Ryzen so for me that part is
academic.
1. The server version of Zen, aimed at Data Centres, so I can
understand why that would get priority.
