Hi,
Can anyone explain me the routing from IOAPIC to LAPIC and how the
LAPIC/vcpu is choosen for the given IRQ.
I found two different structures for IRQ routing and I am little
confused with them.
1. kvm_kernel_irq_routing_entry
2. kvm_irq_routing_entry
And also it will really helpful if someone can tell me how IRQ is mapped
to specific interrupt vector. I believe it will be programmed by the
guest (i.e. guest can change the mapping) but through which API it is
changing and where exactly it is stored.
Thanks,
Senthilkumaran R
