Hi,
from a previous thread I learned which micorcode file needs
to be loaded for the "fight against Spectre and Melddown"...
Now two question came up for me:
1.) WIth this particular micorcode loaded: Do I need to activate
the Spectre/Meldtown fix in the kernel itsself?
2.) Which microcode file gets loaded?
cat /proc/cpuinfo (from one of the six cores):

(***) I think, these microcodes do I need...
Thanks for any help in advance!
