Abstract: Refreshing displays using on-die cache, including: determining that a static display condition has been met; storing, in cache memory of a processor, first display data; and displaying the first display data from the cache memory.

Abstract: A compute device implements a technique for facilitating selective access to hardware codec resources. The compute device executes, in a trusted execution environment, firmware for controlling graphics hardware of a device that supports a plurality of video codecs. The compute device obtains codec control data specific to the device from a remote system and then configures the firmware to implement a codec policy for selectively providing access to the plurality of video codecs based on the codec control data.

Abstract: Systems, apparatuses, and methods for prefetching data by a display controller. From time to time, a performance-state change of a memory are performed. During such changes, a memory clock frequency is changed for a memory subsystem storing frame buffer(s) used to drive pixels to a display device. During the performance-state change, memory accesses may be temporarily blocked. In order to reduce visual artifacts that may occur while the memory accesses are blocked, a memory subsystem includes a control circuit configured to enable a caching mode which caches display data provided to the display controller. Subsequent requests for display data from the display controller are then serviced using the cached data instead of accessing memory.

Abstract: A computing device and method controls power consumption of a graphics processing unit in the computing device by the GPU determining an allocated power for the USB device connected through a USB port, such as a USB-C port. The GPU issues allocated power information for the external USB device to cause the allocated power to be provided to the USB device and includes issuing allocated power information to a power delivery (PD) controller that is connected to a USB port. In some implementations, the GPU shifts at least a portion of the allocated power from the USB device back to the GPU in response to a usage change event associated with the USB device for improving GPU performance. The usage change event can be a disconnect event of the USB device, a power renegotiation event between the USB device and the GPU, or any other suitable usage change event.
