Abstract: The example techniques described in this disclosure may be directed to synchronization between producer shaders and consumer shaders. For example, a graphics processing unit (GPU) may execute a producer shader to produce graphics data. After the completion of the production of graphics data, the producer shader may store a value indicative of the amount of produced graphics data. The GPU may execute one or more consumer shaders, after the storage of the value indicative of the amount of produced graphics data, to consume the produced graphics data.

Abstract: A method and apparatus for processing real time command information includes a real time event engine that monitors event signals. A real time event detector within the real time event engine detects when the real time event occurs. Thereupon, real time event commands within a real time event command buffer are fetched and consumed by the command processor in response to the occurrence of the real time event. The real time event detector contains a plurality of control registers, which contain an event selector register, a real time command buffer point register, and a real time command buffer length register. A driver may program the registers, whereupon a singe real time event detector may be used in conjunction with a plurality of real time event command buffers.

Abstract: This disclosure describes techniques for selectively activating a resume check operation in a single instruction, multiple data (SIMD) processing system. A processor is described that is configured to selectively enable or disable a resume check operation for a particular instruction based on information included in the instruction that indicates whether a resume check operation is to be performed for the instruction. A compiler is also described that is configured to generate compiled code which, when executed, causes a resume check operation to be selectively enabled or disabled for particular instructions. The compiled code may include one or more instructions that each specify whether a resume check operation is to be performed for the respective instruction. The techniques of this disclosure may be used to reduce the power consumption of and/or improve the performance of a SIMD system that utilizes a resume check operation to manage the reactivation of deactivated threads.

Abstract: An apparatus and method for processing pixel depth information eliminates stalling of data in a pixel pipeline, by performing late Z processing for one or more pixels currently in the pixel pipeline and early Z processing for one or more pixels entering the pixel pipeline. The apparatus and method also includes determining whether the late Z processing for the one or more pixels currently in the pixel pipeline has been completed. The apparatus and method also includes solely performing early Z processing for subsequent pixels entering the pixel pipeline responsive to determining that late Z processing for the one or more pixels currently in the pixel pipeline has been completed. The methods and apparatus, facilitates concurrent processing of early and late Z data to avoid flushing portions of the pixel pipeline.

Abstract: In general, techniques are described for visibility-based state updates in graphical processing units (GPUs). A device that renders image data comprising a memory configured to store state data and a GPU may implement the techniques. The GPU may be configured to perform a multi-pass rendering process to render an image from the image data. The GPU determines visibility information for a plurality of objects defined by the image data during a first pass of the multi-pass rendering process. The visibility information indicates whether each of the plurality of objects will be visible in the image rendered from the image data during a second pass of the multi-pass rendering process. The GPU then retrieves the state data from the memory for use by the second pass of the multi-pass rendering process in rendering the plurality of objects of the image data based on the visibility information.

Abstract: This disclosure is directed to deferred preemption techniques for scheduling graphics processing unit (GPU) command streams for execution on a GPU. A host CPU is described that is configured to control a GPU to perform deferred-preemption scheduling. For example, a host CPU may select one or more locations in a GPU command stream as being one or more locations at which preemption is allowed to occur in response to receiving a preemption notification, and may place one or more tokens in the GPU command stream based on the selected one or more locations. The tokens may indicate to the GPU that preemption is allowed to occur at the selected one or more locations. This disclosure further describes a GPU configured to preempt execution of a GPU command stream based on one or more tokens placed in a GPU command stream.
