182 * sDMA - System DMA

186 * and each one supports 1 ring buffer used for gfx
187 * and 2 queues used for compute.
188 *
189 * The programming model is very similar to the CP
190 * (ring buffer, IBs, etc.), but sDMA has it's own
191 * packet format that is different from the PM4 format
192 * used by the CP. sDMA supports copying data, writing
193 * embedded data, solid fills, and a number of other
194 * things. It also has support for tiling/detiling of
195 * buffers.
