regarding microcode patch for intel gen3 and below

Hi, I'm one of Intel's customer who uses Sandybridge-E and Ivybridge-E cpus. [i7-3960X and E5-2667 V2]

Because of recent Meltdown and Spectre issues, I came to know of patches that are going on.

Variant 1 and 3 are patched by MS's windows update patch,

and Variant 2 is patched by m.b manufacturers who got microcodes that are patched by Intel.

As you can see in the latest microcode patch done by Intel, in the releasenote, there's patch for Ivy-E/EN/EP but not for Ivy and any gen below it.

One of your guys at support page led me here to ask a question about it so here it is.

I wanna know how long I have to wait to get patched microcode for them.

First of all, while you likely have already, I suggest that you should review this and associated pages again: Facts about The New Security Research Findings and Intel Products. At the bottom, it includes a list of the affected processor families. All second and third generation Intel Core and Xeon processor are included.

Secondly, Intel's commitment is to have microcode updates available for all affected processors by the end of the month. Any concerns regarding missing microcode before the end of the month are premature and a waste of everyone's time. If you do not see the necessary updates at the end of the month, feel free to yell and scream then...

I understand you are looking for new Linux microcode for your Intel® processors. Let me help you on this matter.

It's possible that some microcode updates will not be included in the download. Some microcode patches can only be delivered via BIOS update, that is why we recommend checking directly with your system manufacturer and OS provided updates.
