The C file does exactly the same, but there are the init functions, which are not called. If I understand these mess right, normally this function is called by device operations. i.e initializing. But these happens on enabled devices, only. cpu_dev_ops seems to be a special case. However, the function model_gx1_init() is never called for some reason. Therefor, x86_enable_cache is not called, too. The northbridge.c file under src/northbridge/amd/gx1 has a similiar init function, it calls the initialize_cpus() function which later calls the cpu_initialize function. But this never happens, too. The captured serial logs have not any debug lines about cpu initializing. chris > > -- > Richard A.
