I am asking below question for understanding. Pls help me to understand
1. How does APIC schedule interrupt on particular core ? How does Apic
takes a decision that first few interrupt will be schedule on Core 0 and
remaining for load balancing will be schedule on different core ? What are
the advantage of scheduling interrupt always on core 0 w.r.t Cache hot
and all ?
2. Is it possible that incoming interrupt can be scheduled on particular
core rather than core 0 ? What is the configuration option or api is
available for that inside kernel or in user space ?
