Abstract: The present disclosure relates to methods and apparatus for graphics processing. An example method generally includes receiving, at a graphics processing unit (GPU), a plurality of commands corresponding to a plurality of draws across a frame, each of the plurality of commands indicating a depth test direction with respect to a low-resolution depth (LRZ) buffer for the corresponding draw. The method generally includes maintaining, at the GPU, a LRZ status buffer to store a corresponding depth test direction for a first command in time of the plurality of commands processed by the GPU. The method generally includes disabling, at the GPU, use of the LRZ buffer for depth testing for any of the plurality of commands remaining unprocessed after processing a command of the plurality of commands having a different depth test direction than the corresponding depth test direction stored in the LRZ status buffer.

Abstract: Methods, systems, and devices for processing are described. In some devices, a command processor (CP) block may determine a first workload type for processing by a graphics processing unit (GPU). The first workload type may be a low power-consuming workload type or a high power-consuming workload type. The CP block may signal a request to a graphics power management unit (GMU) of the GPU to update the upper clock rate of the GPU while processing the first workload type. The GMU may configure the upper clock rate of the GPU based on the request from the CP block and a current limit of the device, and the GPU may process the first workload type based on using the updated upper clock rate.
