An “errate” is what Intel calls an error or defect in its hardware, as far as I know. Microcode is sort of a “firmware” running in a CPU. For example, the TSX feature in Haswells (which was one of the reasons why I chose my particular CPU in the first place, grrr) was found to have a bug, so Intel produced a microcode update that would simply disable the relevant set of instructions. > > no, possibly from a CPU errata and a bios update might bring in the > > microcode update that works around that. > > I see, thanks for clarifying that. So looks like not too many options, > either try to update the bios and/or replace the CPU. Not necessarily. The first search hit (“linux update microcode”) brought me to ¹, another to ². The latter led me to finding sys-apps/microcode-ctl, which might do what you need. ¹ https://wiki.archlinux.org/index.php/Microcode ² http://www.linux-mag.com/id/723/ -- Gruß | Greetings | Qapla’ Please do not share anything from, with or about me with any social network. “Ask us no questions and we’ll tell you no lies.” – Fred Weasley
