i recall the i386/x86_64 port being updated with some code that modifies itself at runtime ... basically you configure the kernel for SMP support but at boot if the kernel detects just one processor, the spinlock code and friends will modify themselves to be nops so there is no runtime overhead compared with building the kernel for a uniprocessor ... anyone know where these implementation details are ? -mike -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
