This was just posted on Thursday? That's a bit too quick for a pull request. I've seen no review from Stefan or Paolo and I would think that given the work that's been done already, it would be counterproductive to enable x-data-plane for another backend. Paolo/Stefan, what do you guys think?

Considering what the patch looks like, I don't think it's a huge problem... In fact, perhaps x-data-plane could be even added to DEFINE_VIRTIO_BLK_PROPERTIES. This would make it clear that support for non-ioeventfd hosts (including TCG) is one of the things to do to make data plane the default. Paolo

Since this patch is so minimal it will not add extra work as we reintegrate dataplane into core QEMU. Acked-by: Stefan Hajnoczi <stefanha@redhat.com>

Any further guidelines on when to ask for acks from you guys? The mode I've been operating in is mostly "if virtio-pci provides this feature, it shouldn't be half bad and we want it in virtio-ccw as well in order to keep things consistent and get more test coverage". (dataplane has been enabled in our internal testing for some time now, I just had asked Dominik to re-do his patch with a proper description as we had some code churn in our internal repository.)

I agree with these guidelines, in fact neither I nor Stefan saw a problem with your patch. :) Paolo

Three days between a post and pull request is a bit short especially with no feedback. That was my primary concern here.

Pulled. Thanks. Regards, Anthony Liguori
