Is an extra branch faster or slower than reverting d57ed95?Sorry, unfortunately I have no way to measure this, as I don't have any virtualization/x86 setup. I'm developing on ARM SoCs, where virtualization hardware is coming, but not here yet.You can try using the micro-benchmark in tools/virtio/.
Hmm, care to show me exactly what do you mean ? Though I somewhat suspect that any micro-benchmarking I'll do with my random ARM SoC will not have much value to real virtualization/x86 workloads. Thanks, Ohad.
