Progress Linux 7.2 – Asahi Linux

Asahi Linux released version 7.2 and made progress on power management for Apple Silicon, a complex challenge involving multiple hardware blocks. The team encountered a technical obstacle: Linux kernel standards mandate using PSCI (Power State Coordination Interface) for CPU power management, but Apple's chips lack the EL3 exception level required to implement it, forcing them to continue using a vendor-specific workaround. They are seeking a proper solution to enable efficient CPU sleep states critical for battery life on Apple Silicon devices.
