amd64-microcode (3.20230808.1) unstable; urgency=high This release requires *either* new-enough system firmware, *or* a recent-enough Linux kernel to properly work on AMD Genoa and Bergamo processors. The firmware requirement is AGESA 1.0.0.8 or newer. The Linux kernel requirement is a group of patches that are already present in the Linux stable/LTS trees since versions: v4.19.289, v5.4.250, v5.10.187, v5.15.120, v6.1.37, v6.3.11 and v6.4.1. These patches are also present in Linux v6.5-rc1. -- Henrique de Moraes Holschuh Thu, 10 Aug 2023 09:32:37 -0300 amd64-microcode (2.20141028.1) unstable; urgency=medium This release drops support for automatically applying microcode updates without a reboot. The microcode updates can still be applied without a reboot through manual action of the system administrator. This is a defensive measure. At this time, there are no reported issues caused by the AMD microcode update itself when done outside of the boot process. However, updating only on boot works around a very elusive issue in the Linux kernel microcode update driver for AMD processors, which may or may not have been fixed in the latest stable/long-term kernels. It is now possible to configure how the amd64-microcode package should behave through the /etc/default/amd64-microcode file. By default, it will install microcode update support to the initramfs only when running in a system with an AMD processor. -- Henrique de Moraes Holschuh Wed, 17 Dec 2014 19:17:30 -0200
