Have you considered using memory registration through a send queue (from the base memory management extensions)? mlx4 at least has support for this operation, which would let you pre-allocate everything and avoid the possibility of failure (I think). When do we get FMR mapping failures now? - R. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
