|
|
* Description:
|
|
* This is the common start-up logic for the IDLE task for CPUs 1 through
|
|
* (CONFIG_SMP_NCPUS-1). Having a start-up function such as this for the
|
|
* IDLE is not really an architectural necessity. It is used only for
|
|
* symmetry with now other threads are started (see nxtask_start() and
|
|
* pthread_start()).
|
|
*
|
|
* Input Parameters:
|
|
* None.
|
|
*
|
|
* Returned Value:
|
|
* This function does not return.

* Name: nx_smp_start

*
|
|
* Description:
|
|
* In an SMP configuration, only one CPU is initially active (CPU 0).
|
|
* System initialization occurs on that single thread. At the completion
|
|
* of the initialization of the OS, just before beginning normal
|
|
* multitasking, the additional CPUs would be started by calling this
|
|
* function.

|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
|
|
* Zero on success; a negated errno value on failure.
|
|
*
|
|
* Assumption:
|
|
* Runs before the full initialization sequence has completed. Runs after
|
|
* all OS facilities are set up, but before multi-tasking has been started.
