The latest Linux 6.16 kernel brings incremental but meaningful improvements for Apple Silicon hardware, including M-Series and A-Series SoCs, as Sven Peter submits Device Tree (DT) updates for upstream integration.
While this cycle isn’t groundbreaking, the refinements enhance compatibility and reporting for Apple’s custom silicon in the open-source ecosystem.
Apple M-Series SoC Updates: SPMI & PMIC Drivers Go Mainstream
The Linux 6.16 merge window includes critical Device Tree patches for Apple M1, M2, and M3 processors, focusing on:
SPMI Controller Support: Enables better power management communication between CPU and peripherals.
PMIC NVMEM Drivers: Facilitates non-volatile memory handling for power management ICs.
Previously maintained downstream by Asahi Linux, these patches now enter the mainline kernel, improving stability for Linux on MacBook Pro, Mac mini, and Mac Studio systems.
Apple A-Series SoC Enhancements: Cache Size Reporting
For older Apple A-Series chips (e.g., A14, A15), Linux 6.16 introduces:
Instruction Cache (I-Cache) Size Reporting
Data Cache (D-Cache) Size Reporting
This optimization aids developers and system tuners in optimizing performance for iOS-to-Linux ports and embedded applications.
Why This Matters for Linux on Apple Silicon
While not a major release, these updates signify:
✅ Progress in Mainline Support: Reducing reliance on downstream forks like Asahi Linux.
✅ Better Hardware Utilization: Smoother power management and cache-aware scheduling.
✅ Future-Proofing: Laying groundwork for upcoming M4 and beyond compatibility.
For developers and enterprise users, this means improved stability for ARM-based Linux workloads on premium Apple hardware.
