Does anybody have a link for (any) updated AMD firmware? Ryzen is
model 17h, AFAICS linux firmware has nothing for that, and the
firmware for earlier models has not been updated in a long time.
I also sure would like a link to that if anyone here knows it. That
said, the Debian page for the AMD microcode is here:
https://packages.debian.org/sid/amd64-microcode
There is also a place on github where Linux related firmware is
distributed from. The AMD CPU microcode area of that is here:
https://github.com/wkennington/linux-firmware/tree/master/amd-ucode
But no updates since 2016 so far. Sigh.
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
Yes, I had seen this as well, but this is specific to Epyc.
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.
I might be confused, but I thought microcode updates on consumer
processors is handled by BIOS update from the motherboard manufacturer,
the AGESA part of the BIOS version, currently 1.0.0.7. I'm not sure if
we'll see a late-load .bin for the consumer processors. If anybody can
confirm or deny, please speak up.
