Hi Ohad, In his comments to my recent vhost RPMsg API patch-set update Michael Tsirkin commented [1], that messages in the RPMsg over VirtIO case should be sent in the LE format. Could you please confirm that you agree with this comment? I'll then go ahead and patch virtio_rpmsg_bus.c firat and then also update my patch-set. In fact you can just reply to the original thread - you're on CC for it too. Thanks Guennadi [1] https://www.spinics.net/lists/kvm/msg217704.html
