The AMD PMC driver used for the SoC power management controller [1]already supports the initial AMD Zen 5 SoCs but new patches coming in as "fixes" for the Linux 6.11 kernel extend the coverage for some upcoming AMD platforms.

Today's batch of platform-drivers-x86 fixes for the Linux 6.11 kernel "Extend support for PMC features on new AMD platform" and "Fix SMU command submission path on new AMD platform."

This "new" AMD platform support is for covering AMD Family 1Ah Model 60h series processors. The 60h series doesn't belong to the recently launched Strix Point (Ryzen AI 3000 series) and Granite Ridge (Ryzen 9000 series desktop CPUs) but is [2]a newer model range that's been appearing in Linux source code in recent months. Whether these model 60h series parts is for Strix Halo, Kraken Point, some custom parts, or some other refresh parts is yet to be figured out.

The AMD PMC driver earlier in the Linux 6.11 cycle began [3]adding the new models while today's pull request gets that new support sorted out.

Whatever these new Family 1Ah Model 60h parts ends up being, it's good as usual seeing AMD getting the Linux support squared away ahead of time. These latest AMD PMC driver patches can be found via this morning's [4]platform-drivers-x86 pull request . That code will likely be merged within the next day or so and be part of the Linux 6.11-rc6 kernel on Sunday.
