Asahi Linux Progress Report: Linux 7.2

Linux 7.2 is out, and the Asahi Linux progress report details the complex power management infrastructure on Apple Silicon, involving hardware blocks like SMC, PMGR, and PMP. A key challenge is handling CPU core sleep modes, with Apple's "deep" WFI mode requiring state saving. The upstream Linux kernel mandates using the standard PSCI interface for power management, which Asahi Linux must implement to avoid vendor-specific hacks.
