| * After Stream Source is completed, we will further scale and |
| * reposition the entire canvas of the stream source to Stream |
| * Destination in Timing Active Space. This could be due to display |

| * the planes so they can fit into a TV with overscan or downscale |
| * upscale features such as GPU scaling or VSR. |
| * |
| * This two step blending is a virtual procedure in software. In |

| * Source space to decouple the math complicity so scaling param |
| * calculation focuses on one step at a time. |
| * |

| * down by the same ratio, Plane Clip position (i.e. x and y) with |

| * In Timing Active Space a plane clip could be further sliced into |
| * pieces called MPC slices. Each Pipe Context is responsible for |
| * processing only one MPC slice so the plane processing workload can be |
| * distributed to multiple DPP Pipes. MPC slices could be blended |
| * together to a single ODM slice. Each ODM slice is responsible for |
| * processing a portion of Timing Active divided horizontally so the |
| * output pixel processing workload can be distributed to multiple OPP |
| * pipes. All ODM slices are mapped together in ODM block so all MPC |
| * slices belong to different ODM slices could be pieced together to |
| * form a single image in Timing Active. MPC slices must belong to |
| * single ODM slice. If an MPC slice goes across ODM slice boundary, it |
| * needs to be divided into two MPC slices one for each ODM slice. |
| * |
| * In the following diagram the output pixel processing workload is |
| * divided horizontally into two ODM slices one for each OPP blend tree. |
| * OPP0 blend tree is responsible for processing left half of Timing |
| * Active, while OPP2 blend tree is responsible for processing right |
| * half. |
| * |
| * The plane has two MPC slices. However since the right MPC slice goes |
| * across ODM boundary, two DPP pipes are needed one for each OPP blend |
| * tree. (i.e. DPP1 for OPP0 blend tree and DPP2 for OPP2 blend tree). |
| * |
| * Assuming that we have a Pipe Context associated with OPP0 and DPP1 |
| * working on processing the plane in the diagram. We want to know the |
| * width and height of the shaded rectangle and its relative position |
| * with respect to the ODM slice0. This is called the recout of the pipe |
| * context. |
| * |
| * Planes can be at arbitrary size and position and there could be an |
| * arbitrary number of MPC and ODM slices. The algorithm needs to take |
| * all scenarios into account. |
