The AMD SoC Power Management Controller Driver is the latest seeing patch activity now in preparing for next-gen Zen 6 processors.

Sent out on Thursday were a set of five patches for the Power Management Controller (PMC) driver with necessary changes for supporting Family 1Ah Model 80h processors that will be part of the Zen 6 processor line-up.

These patches add a new ACPI ID "AMDI000C", address SMU changes with these upcoming processors, and ultimately make the needed preparations for s0i3 power management support with these next-gen wares. The suspend-to-idle "s2idle" functionality has been verified to work correctly on AMD 1Ah Family 80h processors following these AMD PMC Linux driver patches. Quite important these days for optimal power management.

This patch series takes care of the needed AMD PMC Linux driver changes for those upcoming processors. We'll see if these patches manage to make it for next month's Linux v7.2 kernel merge window. This is just a small portion of the overall AMD Zen 6 enablement happening in the open-source ecosystem from other Linux kernel patch activity to the already-enabled GCC and LLVM/Clang znver6 compiler toolchain support.
