Hi, |
| 2 |
|
| 3 |
from a previous thread I learned which micorcode file needs |
| 4 |
to be loaded for the "fight against Spectre and Melddown"... |
| 5 |
|
| 6 |
Now two question came up for me: |
| 7 |
1.) WIth this particular micorcode loaded: Do I need to activate |
| 8 |
the Spectre/Meldtown fix in the kernel itsself? |
| 9 |
2.) Which microcode file gets loaded? |
