In the hope to get everyone on the same page, I created several variants of this patch so they can be compared. Whoever's interested, please check out the following, and tell me how these compare: kernel: git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git virtio-net-limit-xmit-polling/base - this is net-next baseline to test against virtio-net-limit-xmit-polling/v0 - fixes checks on out of capacity virtio-net-limit-xmit-polling/v1 - previous revision of the patch this does xmit,free,xmit,2*free,free virtio-net-limit-xmit-polling/v2 - new revision of the patch this does free,xmit,2*free,free There's also this on top: virtio-net-limit-xmit-polling/v3 -> don't delay avail index update I don't think it's important to test this one, yet Userspace to use: event index work is not yet merged upstream so the revision to use is still this: git://git.kernel.org/pub/scm/linux/kernel/git/mst/qemu-kvm.git virtio-net-event-idx-v3 -- MST -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
