Hi! I see this in virtio_ring.c: /* Put entry in available array (but don't update avail->idx * until they do sync). */ Why is it done this way? It seems that updating the index straight away would be simpler, while this might allow the host to specilatively look up the buffer and handle it, without waiting for the kick. -- MST _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
