A static linked simple hello_world could still run on a non-compat support hardware. But most rv32 apps would meet different userspace segment faults. Current code would let the machine try the rv32 apps without detecting whether hw support or not. -- Best Regards Guo Ren ML: https://lore.kernel.org/linux-csky/
