It's on their twitter

Ah thanks. There isn't much info there about how it works, so I guess I'm gonna get on to some googling.

GREAT Joerg, go for it.
And when 'you' (SUSE) could contact VIA about these _nice_ C7+ (C7-D in my case) that would be even GREATER!
My 'little' file-/phone/WIFI-server is running openSUSE x86 32bit for ages (4.14.14-1.geef6178-pae, now).
Mostly idleling. All power mangement working.
So please, do NOT fade out x86-32 so fast as other distros.

Latest stable kernel show _all_ 'new' bugs. --- But is VIA really affected?
They are enabled for 'all' vendors only exception AMD, currently...

How to check if patches work with a shell script?
