Hi, I've noticed that kvm_irq_delivery_to_apic() is locating the destination APIC by running through kvm_for_each_vcpu() which becomes a scalability issue with a large number if vcpus. I'm thinking about speeding that up using a radix tree for lookups, and was wondering if it sounds right. -- Sasha. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
