File 0606-ucode-properly-include-early-only-ucode.patch of Package dracut.15536
From 2e8648ac1d801c6c35913aa3ffa8198bbb174a70 Mon Sep 17 00:00:00 2001 From: Daniel Molkentin <dmolkentin@suse.com> Date: Thu, 28 Mar 2019 13:46:35 +0100 Subject: [PATCH] ucode: properly include early only ucode Intel has notified us that some microcode updates are not safe to be applied during runtime. To accomodate for that, microcode files shipped by SUSE and openSUSE have an '.early' postfix such that triggering /sys/devices/system/cpu/microcode/reload from a booted system cannot pick up the ucode by accident, while still allowing the code to be picked up during initrd time. This change is needed to make this scheme work also in a hostonly situation. Currently, this affects only 06-4f-01, which is now 06-4f-01.early. If a distro does not change the filename, the behavior does not change.
