The Asahi Linux project demonstrates how to port Linux to Apple Silicon hardware through reverse engineering techniques. The team uses a thin hypervisor to trace MMIO access instead of analyzing disassembly, then develops Linux drivers based on those findings. The talk covers the upstreaming process to the Linux kernel, highlighting how downstream patches have been reduced. Type-C port support serves as a detailed example of the complexity involved, requiring changes across multiple subsystems. The presentation also addresses upcoming challenges with M3/M4/M5 chip support.
