I would have loved to eliminate that EOI completely, but that is a much broader problem to solve ;) Actually dynirq wasnt introduced as a performance alternative over MSI. Rather, I was trying to eliminate the complexity of needing to sync between the userspace PCI emulation and the in kernel models. However, its moot. Since v2 introduce virtio-vbus, I now have a much clearer picture of what is needed here, and v3 will simply integrate with MSI interrupts and drop dynirq completely. So please ignore this patch. -Greg -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
