Abstract: Systems, apparatuses, and methods for implementing fine-grain power management for virtual reality (VR) systems are disclosed. A VR compositor monitors workload tasks while rendering and displaying content of a VR application. The VR compositor determines the priorities of different tasks of a given VR frame and cause power states to be assigned to processing units to match the priorities of the tasks being performed. For example, if a first task within a first frame period is assigned a high priority, a processing unit executing the task operates at a relatively high power performance state when performing the first task. If a second task within the first frame period is assigned a low priority, the processing unit operates at a relatively low power performance state when performing the second task. By implementing fine-grain power management in a VR environment, the likelihood of the processing unit suffering a thermal event or impaired performance is reduced.

Abstract: Systems, apparatuses, and methods for abstracting tasks in virtual memory identifier (VMID) containers are disclosed. A processor coupled to a memory executes a plurality of concurrent tasks including a first task. Responsive to detecting one or more instructions of the first task which correspond to a first operation, the processor retrieves a first identifier (ID) which is used to uniquely identify the first task, wherein the first ID is transparent to the first task. Then, the processor maps the first ID to a second ID and/or a third ID. The processor completes the first operation by using the second ID and/or the third ID to identify the first task to at least a first data structure. In one implementation, the first operation is a memory access operation and the first data structure is a set of page tables. Also, in one implementation, the second ID identifies a first application of the first task and the third ID identifies a first operating system (OS) of the first task.

Abstract: A computer vision processor in an image cluster defines a fenced memory region (FMR) that controls access to image data stored in a first portion of a trusted memory region (TMR). The computer vision processor receives FMR requests from an application implemented in a processing cluster. The FMR requests are to access the image data in the first portion of the TMR. The computer vision processor selectively allows the requesting application to access the image data. In some cases, the computer vision processor acquires the image data and stores the image data in the first portion of the TMR, such as buffers in the TMR. A data fabric selectively permits the image processing application to access the data stored in the TMR based on whether the image cluster has opened or closed the FMR for the portion of the TMR.
