intel-microcode upate downloaded from Intel differs from Ubuntu package
[posting in Answers because not sure this is a bug, but it looks odd ...]
I was reading the kernel boot messages and got curious whether the Intel microcode on my CPU, a Core 2 Quad Q8400 had a Spectre, etc, update.
I found this page:
https:/
which if I understood correctly lists my CPU as having a microcode update in 2018. However my dmesg output indicates the microcode was updated but to a 2010 version.
(This is on xenial's kernel 4.4.141; the intel-microcode package installedq is 3.20180807a.
I downloaded the intel package and located the installed intel-microcode files; there are quite a number of "missing" files (I presume these relate to ) and some binary file differences. I examined a couple of the files and there is at least some similarity between them. For example, f0-06-05 Intel has a blob prefixed to the Ubuntu one.
Do these differences explain why my CPU is not being updated, or is there some other reason?
Why are there differences here in any case?
