>>713378310Multiplane Overlay (MPO) allows for multiple framebuffers to be composited via fixed-function hardware in the display controller rather than using graphics or compute shaders for composition. This can yield some power savings if it means the graphics/compute pipelines can be put into low-power states. In summary, MPO can bring the following benefits:
Decreased GPU and CPU workload - no composition shaders needed, no extra buffer copy needed, GPU can remain idle.
Plane independent page flips - No need to be tied to global compositor page-flip present rate, reduced latency, independent timing.
