Sorry for the back and forth, I've been pondering MST's points. If we make a new dma-multiport device (eg. ID 11), how ugly is the code? It would be a virtio console with DMA buffers and no console, just the multiport stuff. This would have no impact on the current spec for virtio console. Thanks, Rusty. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
