[-- Attachment #1 --] In FreeBSD does there exist a similar function or a combination of functions to do the same thing as NetBSD's bus_dmamap_load_uio()? This function is a variation of the bus_dmamap_load(), which maps buffers pointed to by uio for DMA transfers. The value of uio->uio_segflg determins if the buffer is in user or kernel space.
