Please test early update of microcode for AMD CPUs using an amd-microcode package.

Please find a package and instructions for testing in this repository. Top of the README below:

This repository contains files needed to test the package amd-microcode on Slackware or derivatives. The goal of testing is to check that after installation of this package and update of GRUB's /boot/grub/grub.cfg accordingly, at boot the microcode of AMD CPUs is updated early in the boot process.

Rationale:

• Many (most) users do not keep their firmware up to date installing a new version when available, although these updates would alleviate security risks and functional issues.
• But the Linux Microcode Loader allows to instead update the microcode, either integrating the updated files in it or applying them at each boot, through an initrd file.
• It is preferable to use an initrd loaded early, to avoid having to rebuild a kernel every time new microcode files are available for either Intel or AMD.
• The updated microcode files (presented in a CIPO archive as an intrd file) can then either integrated in a main initrd (like the one that can write mknitrd or dracut) or be in /boot, loaded early by the boot loader.

For Slint GRUB will load the microcode early and this is my recommendation for Slackware 15.1 as well. This way grub.cfg will need to be updated only once (after the microcode file has been included in /boot for the first time) as its name won't change after an update.

I request testing of this package and method here because I can't test myself by lack of a computer with an AMD CPU and as this feature could be included in Slackware without any modification.

I do not request testing this method for Intel CPUs (using an intel-microcode package for which a SlackBuild is available) as I have successfully tested it myself
