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 and methods for selecting and setting clock frequencies for an electronic device are disclosed. Specifically, clock frequencies may be adjusted to avoid interference with input electromagnetic energy, often in radio frequency bands. Clock frequencies may be chosen to minimize signal interference and improve device performance. In some embodiments, clock frequency information is stored in one or more lookup tables in device memory. In certain embodiments, a system processor can access the information stored in the lookup table and instruct system circuitry to adjust clock frequency as needed based on lookup table entries.
