Moving forward I see MIPS mainly used in embedded systems. I think need of using the same kernel binary for multiple CPUs is rare, especially for the "same" CPU with or without FPU. Therefore having run-time detection is a waste of effort. Half-config-half-runtime solution is pretty messy too. For CPUs with the same PrID that may or may not have a FPU, we can add an optional FPU selection in the config.in file. To be complete, I probably would add a check for the existence of FPU, if we can infer from PrID, when FPU config option is enabled. Jun
