AMD has submitted five patches to update the SoC Power Management Controller (PMC) driver for its processors. The goal is to add support for the upcoming Zen 6 chips, identified with family 1Ah and model 80h. The update includes a new ACPI ID (AMDI000C) and necessary adjustments to ensure s0i3 power management and s2idle suspension, features already verified on these processors.
Technical details of the patches for Zen 6 🔧
The patches introduce changes to the PMC driver to recognize the new ACPI ID AMDI000C, specific to Zen 6 processors. The power state tables and initialization routines have been adjusted to ensure compatibility with the low-power modes s0i3 and s2idle. AMD confirmed that idle suspension tests already work correctly on these chips, indicating that the driver integration is advanced and ready for upcoming platforms.
Another patch, another promise of energy savings 😅
Five patches so your future processor consumes less when you're not doing anything. It seems like a master plan: first they sell you a chip that guzzles power like a power plant, and then they spend months patching its power management. But hey, while the competition is also sweating over their own controllers, at least AMD assures us that s2idle will work. Of course, don't ask how many patches it will take for the battery to last more than an afternoon.
