AMD has sent five patches to update the SoC Power Management Controller (PMC) driver of its processors. The goal is to add support for the upcoming Zen 6 chips, identified by the 1Ah family and the 80h model. The update includes a new ACPI ID (AMDI000C) and the necessary adjustments to guarantee s0i3 energy management and s2idle suspension, functions already verified on these processors.
Technical details of fixes for Zen 6 🔧
The fixes introduce changes to the PMC driver to recognize the new ACPI ID AMDI000Cspecific to Zen 6 processors. The energy state tables and initialization routines have been adjusted to ensure compatibility with the s0i3 and s2idle low-power modes. AMD has confirmed that suspend testing is already working properly on these chips, indicating that driver integration is advanced and ready for upcoming platforms.
Another fix, another promise of energy savings 😅
Five fixes so that your future processor consumes less when you’re doing nothing. This sounds like a brilliant plan: first, they sell you a chip that consumes like a power plant, then they spend months fixing its power management. But hey, while the competition is also sweating over its own drivers, at least AMD assures us that the s2idle will work. Of course, don’t ask how many fixes will be needed to make the battery last more than an afternoon.
