/** * DOC: overview * * Multiple Pipe/Plane Combiner (MPC) is a component in the hardware pipeline * that performs blending of multiple planes, using global and per-pixel alpha. * It also performs post-blending color correction operations according to the * hardware capabilities, such as color transformation matrix and gamma 1D and * 3D LUT. * * MPC receives output from all DPP pipes and combines them to multiple outputs * supporting "M MPC inputs -> N MPC outputs" flexible composition * architecture. It features: * * - Programmable blending structure to allow software controlled blending and * cascading; * - Programmable window location of each DPP in active region of display; * - Combining multiple DPP pipes in one active region when a single DPP pipe * cannot process very large surface; * - Combining multiple DPP from different SLS with blending; * - Stereo formats from single DPP in top-bottom or side-by-side modes; * - Stereo formats from 2 DPPs; * - Alpha blending of multiple layers from different DPP pipes; * - Programmable background color;
