Methods and apparatus for incremental resource allocation for jank free composition convergence

An apparatus for display processing, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• identify an adjustment in one or more layers of a plurality of layers in a current frame compared to one or more layers of a plurality of layers in a previous frame;
• determine, upon identifying the adjustment in the one or more layers, a first resource allocation for each of the plurality of layers, the first resource allocation being associated with a composition process for the plurality of layers;
• determine, after the determination of the first resource allocation begins, a second resource allocation for each of the plurality of layers, the second resource allocation being associated with the composition process for the plurality of layers;
• initiate, upon determining the first resource allocation, an execution of the composition process for each of the plurality of layers in the current frame based on the first resource allocation;
• and
• initiate, upon determining the second resource allocation, an execution of the composition process for each of the plurality of layers in at least one subsequent frame based on the second resource allocation.

An apparatus for display processing, comprising:

• means for identifying an adjustment in one or more layers of a plurality of layers in a current frame compared to one or more layers of a plurality of layers in a previous frame;
• means for determining, upon identifying the adjustment in the one or more layers, a first resource allocation for each of the plurality of layers, the first resource allocation being associated with a composition process for the plurality of layers;
• means for determining after the determination of the first resource allocation begins, a second resource allocation for each of the plurality of layers, the second resource allocation being associated with the composition process for the plurality of layers;
• means for initiating, upon determining the first resource allocation, an execution of the composition process for each of the plurality of layers in the current frame based on the first resource allocation;
• and
• means for initiating, upon determining the second resource allocation, an execution of the composition process for each of the plurality of layers in at least one subsequent frame based on the second resource allocation.

A computer-readable medium storing computer executable code for display processing, the code when executed by a processor causes the processor to:

• identify an adjustment in one or more layers of a plurality of layers in a current frame compared to one or more layers of a plurality of layers in a previous frame;
• determine, upon identifying the adjustment in the one or more layers, a first resource allocation for each of the plurality of layers, the first resource allocation being associated with a composition process for the plurality of layers;
• determine, after the determination of the first resource allocation begins, a second resource allocation for each of the plurality of layers, the second resource allocation being associated with the composition process for the plurality of layers;
• initiate, upon determining the first resource allocation, an execution of the composition process for each of the plurality of layers in the current frame based on the first resource allocation;
• and
• initiate, upon determining the second resource allocation, an execution of the composition process for each of the plurality of layers in at least one subsequent frame based on the second resource allocation.
