[gentoo-user] Ryzen initial results.

[Alan Grimes]

I installed my Ryzen system today, using a mATX b350 mobo.

My existing kernel mostly works,

I should probably break my version freeze on my kernel but I am deeply
concerned about nvidia_drivers compatibility... =\

From what I've been reading, Ryzen support wasn't added until 4.10, with
partial support in 4.9. So you probably won't get everything out of your
new hardware.

I am using 4.9.16 on my laptop with binary nvidia drivers, I haven't had
issues yet. Although, it is one of those dual-gpu models, intel and
nvidia - but the nvidia kernel module loads with no erroneous messages.

If you have bleeding edge hardware you really need to use a newer kernel
for proper support. I didn't even try my new laptop with an old kernel
(most of my other machines are on 4.1 LTS still.)

Ditto. With a bleeding edge hardware one needs a bleeding edge
software, at least kernel, drivers/firmware and @system.
