  • Patent number: 10373287
    Abstract: Systems, methods, and computer readable media to improve task switching operations in a graphics processing unit (GPU) are described. As disclosed herein, the clock rate (and voltages) of a GPU's operating environment may be altered so that a low priority task may be rapidly run to a task switch boundary (or completion) so that a higher priority task may begin execution. In some embodiments, only the GPU's operating clock (and voltage) is increased during the task switch operation. In other embodiments, the clock rate (voltages) of supporting components may also be increased. For example, the operating clock for the GPU's supporting memory, memory controller or memory fabric may also be increased. Once the lower priority task has been swapped out, one or more of the clocks (and voltages) increased during the switch operation could be subsequently decreased, though not necessarily to their pre-switch rates.

  • Publication number: 20190213776
    Abstract: One disclosed embodiment includes a method of scheduling graphics commands for processing. A plurality of micro-commands is generated based on one or more graphics commands obtained from a central processing unit. The dependency between the one or more graphics commands is then determined and an execution graph is generated based on the determined dependency. Each micro-command in the execution graph is connected by an edge to the other micro-commands that it depends on. A wait count is defined for each micro-command of the execution graph, where the wait count indicates the number of micro-commands that the each particular micro-command depends on. One or more micro-commands with a wait count of zero are transmitted to a ready queue for processing.

  • Publication number: 20190108037
    Abstract: One disclosed embodiment includes a method of graphics processing. The method includes receiving an indication to update a current frame on a display. A plurality of graphics command are determined to be associated with a next frame that replaces the current frame. A power-up command is generated based on the received indication, configured to cause GPU hardware to begin an initialization operation. The central processing unit processes the plurality of graphics command. Prior to completely process the plurality of graphics command, a power-up command is sent to a GPU firmware. The GPU firmware initializes the GPU hardware based on the power-up command. The processed plurality of graphics command is also transmitted to the GPU hardware. The GPU hardware executes the processed plurality of graphics command to render the next frame on the display.

  • Publication number: 20180349146
    Abstract: In general, techniques are disclosed for tracking and allocating graphics processor hardware over specified periods of time. More particularly, hardware sensors may be used to determine the utilization of graphics processor hardware after each of a number of specified intervals (referred to as “sample intervals”). The utilization values so captured may be combined after a first number of sample intervals (the combined interval referred to as an “epoch interval”) and used to determine a normalized utilization of the graphic processor's hardware resources. Normalized epoch utilization values have been adjusted to account for resources used by concurrently executing processes. In some embodiments, a lower priority process that obtains and fails to release resources that should be allocated to one or more higher priority processes may be detected, paused, and its hardware resources given to the higher priority processes.
