intel-microcode

Post by thx-1138 » Sat Apr 29, 2017 6:03 am

...on my system, the Driver Manager detects & offers intel-microcode 3.20151106. I think it does so by quering Ubuntu's 'restricted extras' repos for Xenial.

While browsing Intel's site, i noticed there's a much newer microcode version released since November 2015:
https://downloadcenter.intel.com/downlo ... -Data-File

Ubuntu seems to provide the newer microcode...but it offers it only in Yakkety and afterwards releases.
https://launchpad.net/ubuntu/+source/intel-microcode
http://ftp.ubuntu.com/ubuntu/ubuntu/poo ... microcode/

I think it would be beneficial if Mint's update / package mechanism would 'automagically' always offer by default the latest microcode released by Intel...

Mint is based on the LTS version of Ubuntu. Linux Mint 18 and the point releases (18.1, 18.2) use the Xenial LTS (16.04) base. Yakkety is a short term base (17.xx) so there could be conflicts with packages that aren't officially for the LTS-based versions. Installing drivers not specifically for a release could totally fubar your Mint. With Mint's reputation as a "Linux distro that works out of the box" I am sure the developers would include the drivers you mentioned if they feel they are necessary and stable.

o-l-d, it's microcode, firmware meant to run / enhance your processor...it's not a 'driver' in the usual sense:
https://wiki.archlinux.org/index.php/microcode

Theoritically speaking, if someone keeps his/her BIOS regularly updated, most likely he / she doesn't need it, as it's supposed to be already included there...
Most people don't do so though i think...plus, lots of end-users can't do it easily as well (vendors don't always provide a Linux-friendly way to update their BIOS)...

As you can see, for the most part of it, it's relatively 'OS agnostic'...someone can simply use iucode-tool to manually install such. But if still in doubt in regards to LTS etc, well, Intel's site itself clearly mentions Ubuntu 16.04x...
https://downloadcenter.intel.com/downlo ... -Data-File

By the way, there's also a newer version released from what i see above, microcode-20170511.
There was a discovery of an exploit against Intel AMT/ME that made the fuzz out there earlier this month, so i assume this doesn't come as a surprise...

Agreed and thanks for the further explanation. Most linux users are using older hardware (as I do since my "newest" is 5 years old) and BIOS updates from the system manufacturer aren't available to a great extent.
