76 * sDMA - System DMA
77 * Starting with CIK, the GPU has new asynchronous
78 * DMA engines. These engines are used for compute
79 * and gfx. There are two DMA engines (SDMA0, SDMA1)
80 * and each one supports 1 ring buffer used for gfx
81 * and 2 queues used for compute.
82 *
83 * The programming model is very similar to the CP
84 * (ring buffer, IBs, etc.), but sDMA has it's own
85 * packet format that is different from the PM4 format
86 * used by the CP. sDMA supports copying data, writing
87 * embedded data, solid fills, and a number of other
88 * things. It also has support for tiling/detiling of
89 * buffers.
