[Hardware] Linux 6.6 Receives Patches For AMD’s Next-Gen Zen 5 CPUs

[BirSaNN]

As AMD's next-gen Zen 5 CPUs come close to launch, it seems like Linux 6.6 has started to receive new patches based on the upcoming "Family 1Ah" architecture.

The newly emerged patches reveal that AMD has provided support for Error Detection and Correction (EDAC) along with "k10temp", which is utilized for monitoring CPU temperatures, for its upcoming Zen 5 CPUs. These are the initial set of patches that cover the basic needs of a processor, and we anticipate several patches to get uploaded in the future as well.

Phoronix also highlights that the new driver changes were pending in a kernel TIP branch, and it is expected that more patches are in the pipeline, possibly emerging on the "Linux 6.6 merge window" which is slated at the end of August. Following are more details on the patches and their functionality:

EDAC/amd64: Add support for AMD family 1Ah models 00h-1Fh and 40h-4Fh

Add support for family 1Ah-based models 00h-1Fh and 40h-4Fh.
hwmon: (k10temp) Add thermal support for AMD Family 1Ah-based models

Add thermal info support for AMD Family 1Ah-based models. Support is provided on a per-socket granularity.
x86/amd_nb: Add PCI IDs for AMD Family 1Ah-based models

Add new PCI Device IDs required to support AMD's new Family 1Ah-based models 00h-1Fh, 20h, and 40h-4Fh.
AMD already has Zen 5 CPUs running in its labs which is made evident by the numerous spottings of early samples within various databases such as the one here.

With the immense popularity of Team Red in Linux platforms, the company has been fairly quick in releasing next-gen support. This includes improvements being made with the open-source Radeon Vulkan drivers, along with several optimization fixes. With the lion's share of the platform, we expect AMD to deliver patches for upcoming launches early; hence make sure to keep following since they sometimes tend to reveal something interesting.
