RTEMS C User's Guide
The System Initialization Task is responsible for initializing all device drivers. As a result, this task has a higher priority than all other tasks to insure that no application tasks executes until all device drivers are initialized. After device initialization in a single processor system, this task will delete itself.
The System Initialization Task must have enough stack space to successfully execute the initialization routines for all device drivers and, in multiprocessor configurations, the Multiprocessor Communications Interface Layer initialization routine. The CPU Configuration Table contains a field which allows the application or BSP to increase the default amount of stack space allocated for this task.
In multiprocessor configurations, the System Initialization Task does not delete itself after initializing the device drivers. Instead it transforms itself into the Multiprocessing Server which initializes the Multiprocessor Communications Interface Layer, verifies multiprocessor system consistency, and processes all requests from remote nodes.
