This looks to be BSP specific and could originate in configure.ac or a .h file. It is likely that each BSP has an underlying hardware limit. > >rtems_configuration_get_maximum_processors() called in gets this >configured number. But I don't know from where. This is set initially based on the confdefs.h parameter CONFIGURE_SMP_MAXIMUM_PROCESSORS or something close to that (on phone). Ultimately the maximum CPUs for an application is the lower of those available or RTEMS is configured for. >Also where is RTEMS_SMP defined for a bsp?
