From 17882e76afc0e69a0d4ed142aa33b94017ae4e58 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Fri, 15 Mar 2024 17:43:49 +0000 Subject: [ucode] Add support for updating x86 microcode Intel and AMD distribute microcode updates, which are typically applied by the BIOS and/or the booted operating system. BIOS updates can be difficult to obtain and cumbersome to apply, and are often neglected. Operating system updates may be subject to strict change control processes, particularly for production workloads. There is therefore value in being able to update the microcode at boot time using a freshly downloaded microcode update file, particularly in scenarios where the physical hardware and the installed operating system are controlled by different parties (such as in a public cloud infrastructure). Add support for parsing Intel and AMD microcode update images, and for applying the updates to all CPUs in the system.
