+.SH "DESCRIPTION"
+.PP
+If an audio driver manages the DMA buffer itself (it has the alloc_buffer and
+free_buffer methods in it's callback table) it can set the DMA buffer address
+using \fIossddk_dmap_set_dmabuf\fR. The buffer size can be set using
+\fIossddk_dmap_set_buffsize(9ossddk)\fR.
+.PP
+In addition to the virtual address the driver should usually set the physical
+memory/bus address too using \fIossddk_dmap_set_phys(9ossddk)\fR.
