Should it go (1) virtio spec (2) kernel (3) qemu, or should it go (2), (1), (3)?1. Informal discussionWhere? Is this lkml? There were a number of virtio changes recently that never involved qemu-devel.Theoretically, address@hidden, if it still exists. Maybe we need a virtio list. qemu-devel@, kvm@, lkml could be copied.Perhaps it's time to create a address@hidden Just have a simple process that all spec changes to there the appropriate kernel, QEMU, virtio-win, or NKT maintainers can require any virtio change to also have a committed spec change first.Historically address@hidden was used, that is still low enough volume. It was down but seems to be up now. It's easy enough for me to subscribe to yet another list but my concern is that if we move we might loose some people that don't notice the change. Anything wrong with just using the old list?
No, but it's so old, I have no idea who admin's it these days.
It's on the MAINTAINERS file, I'm not sure why it was bypassed in this case. Maybe linux-foundation.org was still down when the patch was posted?
The list has been down for a while.
2. Proposed spec patch, kernel change, qemu change 3. Buy-ins from spec maintainer, kernel driver maintainer, qemu device maintainer (only regarding the ABI, not the code)I don't think this is how it's working today. I would be happy with a flow like this.If Michael and Rusty agree, we can adopt it immediately.If I understand the proposal, what is suggested is that all of spec, kvm and virtio patches are posted on list and acked before merging any one of them? Sure, this makes sense.
Well, what's needed before the spec is changed is an interesting question, but I think the main thing is, don't commit any virtio ABI changes to vhost, QEMU, NKT, or the kernel until the spec for the change has been committed.
It would be nice to have a working implementation before committing a spec change. Even nicer would be to have Acked-by's a maintainer in each area affected.
