Abstract: Methods, systems, and devices for dependency detection of a graphical processor unit (GPU) workload at a device are described. The method relates to generating a resource packet for a first GPU workload of a set of GPU workloads, the resource packet including a list of resources, identifying a first resource from the list of resources, retrieving a GPU address from a first memory location associated with the first resource, determining whether a dependency of the first resource exists between the first GPU workload and a second GPU workload from the set of GPU workloads based on the retrieving of the GPU address, and processing, when the dependency exists, the first resource after waiting for a duration to lapse.

Abstract: Techniques are described for generating image content for display. A host processor may read opacity information generated by processing circuitry for one or more blocks of pixels of a first layer of a plurality of layers. The host processor may determine an inner rectangular portion of the first layer that is substantially opaque based on the read opacity information, and instruct a display processor to not retrieve, for use in composing the plurality layer, an area of a second layer of the plurality of layers that is occluded by the inner rectangular portion of the first layer. The display processor may compose the plurality of layers to generate an image frame for display.
