摘要： One embodiment of the present invention sets forth a technique for providing state information to one or more shader engines within a processing pipeline. State information received from an application accessing the processing pipeline is stored in constant buffer memory accessible to each of the shader engines. The shader engines can then retrieve the state information during execution.

摘要： A method for providing state inheritance across command lists in a multi-threaded processing environment. The method includes receiving an application program that includes a plurality of parallel threads; generating a command list for each thread of the plurality of parallel threads; causing a first command list associated with a first thread of the plurality of parallel threads to be executed by a processing unit; and causing a second command list associated with a second thread of the plurality of parallel threads to be executed by the processing unit, where the second command list inherits from the first command list state associated with the processing unit.

摘要： Systems and methods for auto-throttling encapsulated compute tasks. A device driver may configure a parallel processor to execute compute tasks in a number of discrete throttled modes. The device driver may also allocate memory to a plurality of different processing units in a non-throttled mode. The device driver may also allocate memory to a subset of the plurality of processing units in each of the throttling modes. Data structures defined for each task include a flag that instructs the processing unit whether the task may be executed in the non-throttled mode or in the throttled mode. A work distribution unit monitors each of the tasks scheduled to run on the plurality of processing units and determines whether the processor should be configured to run in the throttled mode or in the non-throttled mode.

摘要： One embodiment of the present invention sets forth a technique for tracking and filtering state change methods provided to a graphics pipeline. State shadow circuitry at the start of the graphics pipeline may be configured in different modes. A track mode is used to capture the current state by storing state change methods that are transmitted to the graphics pipeline. A passthrough mode is used to provide different state data to the graphics pipeline without updating the current state stored in the state shadow circuitry. A replay mode is used to restore the current state to the graphics pipeline using the state shadow circuitry. Additionally, the state shadow circuitry may also be configured to filter the state change methods that are transmitted to graphics pipeline by removing redundant state change methods.

摘要： One embodiment of the present invention sets forth a method macro expander (MME) coupled to a driver and the processing pipeline of a graphics processing unit. In operation, the MME receives, from the driver, a first packet of work indicating a macro stored in an instruction memory that is to be executed. The MME then executes the commands of the macro in the instruction memory to generate a second packet of work, and the second packet of work is then transmitted to the processing pipeline for further execution.
