I'm trying to use bus_dmamem_alloc. The function man says: /* * Allocate a piece of memory that can be efficiently mapped into * bus device space based on the constraints listed in the dma tag. * A dmamap to for use with dmamap_load is also allocated. */
so I'm running: err = bus_dmamem_alloc(ring->dma_tag, &ring->buf, BUS_DMA_NOWAIT|BUS_DMA_ALLOCNOW, &ring->dma_map); but after calling bus_dmamem_allloc the dma_map variable is still NULL. is this OK?
