An “errate” is what Intel calls an error or defect in its hardware, as far |
11 |
as I know. Microcode is sort of a “firmware” running in a CPU. For example, |
12 |
the TSX feature in Haswells (which was one of the reasons why I chose my |
13 |
particular CPU in the first place, grrr) was found to have a bug, so Intel |
14 |
produced a microcode update that would simply disable the relevant set of |
15 |
instructions. |

Not necessarily. The first search hit (“linux update microcode”) brought me |
24 |
to ¹, another to ². The latter led me to finding sys-apps/microcode-ctl, |
25 |
which might do what you need. |
