Questions concering microcode releases

bpw — Sun, 25 Aug 2024 14:22:29 GMT

Hi,

The Intel Github repo (https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files) contains MCU releases for processors that support OS loading of MCUs, so it should cover Intel's 12th/13th and 14th gen CPUs.

However, I was unable to find newer Raptor Lake MCUs like 0x125 and 0x129 in this repository. Likewise, my own i9-12900K already reports microcode version 36, while the Github repository contains only version 35 for that processor.

What is Intel's publication strategy/schedule here? Is this Github repository supposed to eventually contain the complete microcode update revision history for all applicable processors? If not, is there such a complete microcode revision history available elsewhere?

Thanks

For all Intel Core 13th/14th Gen desktop processor users: This patch is being distributed via BIOS update and will not be available through operating system updates.

Source: https://community.intel.com/t5/Processors/Microcode-0x129-Update-for-Intel-Core-13th-and-14th-Gen-Desktop/m-p/1622129

Presumably also applies to 0x125.

Thanks, but that answers only part of my questions, that are not specific to the current 13th/14th gen processor issues.

Is there a comprehensive microcode revision history available that includes all MCUs (regardless if distributed via OS or BIOS-only)?
