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.
