Porting NetBSD to new hardware architectures involves several challenges, some of which are quite technical and intricate. Here are some of the main challenges developers face:
Architecture-Specific Code: NetBSD has a significant amount of architecture-specific code, particularly in low-level areas like boot loaders, device drivers, and system initialization routines. Adapting this code to a new architecture requires a deep understanding of both NetBSD's internals and the new hardware's specifics.
