Intel-Linux-Processor-Microcode-Data-Files VS nonguix

So where is the microcode update? I don't see anything for Linux yet.

https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/blob/main/releasenote.md looks like they released a new microcode (24000024) affecting these units on Feb 14th this year.

Package: intel-microcode Version: 3.20221108.1 Priority: optional Section: non-free/admin Maintainer: Henrique de Moraes Holschuh Installed-Size: 6460 kB Depends: iucode-tool (>= 1.0) Recommends: initramfs-tools (>= 0.113~) Conflicts: microcode.ctl (<< 0.18~0) Homepage: https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files Tag: hardware::TODO, role::app-data, use::driver Download-Size: 4509 kB APT-Sources: http://deb.debian.org/debian testing/non-free amd64 Packages Description: Processor microcode firmware for Intel CPUs

They have been sort of cracked, but it doesn't matter. The web or chain of trust of those updates from the vendor to the processor is what matters. They're at least CRC checked to prevent loading corrupt files.

Not to “well aktchually”, but all modern processors do have regularly updated microcode that’s uploaded at boot time - https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files

6-94-3 would become 6-5E-3. https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/blob/6c0c4691e5bb446e0e428ebca595164709c59586/intel-ucode/06-5e-03

OpenBSD kernel has no support for loading microcode on AMD CPUs, A number of issues/errata on AMD systems may be fixed as part of AGESA updates, in addition to microcode as part of BIOS/firmware updates. While there have been microcode updates released for Zen+ or newer CPUs, but these seem to be less frequent than Intel.

I use the nonguix channel for non-free stuff https://gitlab.com/nonguix/nonguix. It has the mainline linux kernel (instead of the free linux-libre), proprietary drivers and a bunch of other proprietary stuff.

Guix has these things called "channels" containing package definitions. They're actually just git repositories. nonguix was made to have nonfree stuff. It has a lot of stuff including the mainline linux kernel.

https://gitlab.com/nonguix/nonguix you can use non free software if you need to. But the project itself is a gnu project and as such should not encourage users to use non free software.

I think Guix approach is good, community helps with open-source packages, some third-party manages the non-free channels. And they are as easy to use

There are flatpacks, snaps, appimages, PPAs, channels... why would you except a linux distro maintainer to work for free for a billion dollar company? Testing and maintain their software

My background consists of using/developing Guix, openSUSE/SUSE as well of OBS. I'm a co-maintainer at nonguix, where we provide non-free software which is not allowed at upstream Guix. We even run our own little build service, called Cuirass. This softwore is developed mostly by https://www.reddit.com/user/mothacehe/ :)

Thanks for the link. Although I was just planning to follow the steps in the https://gitlab.com/nonguix/nonguix repo.

You'll want to read about "channels" which are additional software repositories you can include in Guix from anywhere, There are other channels, but the main one for non-free is https://gitlab.com/nonguix/nonguix

Even GNU Guix System (which is a fully libre, FSF approved distro) can be used to install non-free packages. All you have to do is add the nonguix repository.
