As you and I have discussed, there was an issue in that EVERY core was stepped up and all had to come to the same state. I know that we want to be able to run on a subset of CPU cores so this is undesirably rigid.
Yes and statically controlling this in RTEMS via a configuration table needs to be discussed. The number of operating cores may be driven by a complex application based configuration.
But the idea that the secondary cores that ARE available do not execute threads until we are ready is still needed. Basically, the initialization needs to be single threaded until we want to use the other cores.
This means we need to embed into RTEMS the ability to control cores which is something I think we need to support.
