Hi All: I want to do some modification on the SMP architecture. Purpose: Only the first CPU is running the linux OS, while others do some private services processing. My solution: In the end of the start_secondary() function, I try to schedu the slave cpu to call my private endless loop instead of cpu_idle(); Result: The system can NOT up, there is no interactive cli. Question: Is there some wrong with my modification or I go to the wrong way? Thank you very much. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
