10 fixed-function hardware in the display controller rather than using graphics or
11 compute shaders for composition. This can yield some power savings if it means
12 the graphics/compute pipelines can be put into low-power states. In summary,
13 MPO can bring the following benefits:
15 * Decreased GPU and CPU workload - no composition shaders needed, no extra
16 buffer copy needed, GPU can remain idle.
17 * Plane independent page flips - No need to be tied to global compositor
18 page-flip present rate, reduced latency, independent timing.
20 .. note:: Keep in mind that MPO is all about power-saving; if you want to learn
