Another iteration of virtio-1 patches for qemu, as always available on git://github.com/cohuck/qemu virtio-1 This one seems to work together with the current vhost-next patches (well, I can ping :) Changes from v4: - add helpers for feature bit manipulation and checking - use 64 bit feature bits instead of 32 bit arrays - infrastructure to allow devices to offer different sets of feature bits

And yet another iteration of virtio-1 support in qemu, tested with the latest virtio kernel patches. Find it at git://github.com/cohuck/qemu virtio-1 Changes from v5: - fixed stupid bug in "virtio: support more feature bits": we need to define a proper prop backend for 64 bit wide handling... - don't negotiate revision 1 unless VERSION_1 is offered - use 64 bit wide features
