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.
Claims20
A computer-implemented method comprising:
- executing, in a trusted execution environment of a compute system, firmware for controlling graphics hardware of a device that supports a plurality of video codecs;
- obtaining, at the device, codec control data specific to the device from a remote system;
- and
- implementing, at the device, a codec policy for selectively providing access to the plurality of video codecs based on the codec control data.
An apparatus comprising:
- a device having a security processor to provide a trusted execution environment and graphics hardware that supports a plurality of video codecs, the device to:
- execute firmware at the security processor for controlling the graphics hardware;
- obtain codec control data specific to the device from a remote system;
- and
- implement a codec policy for selectively providing access to the plurality of video codecs at the graphics hardware based on the codec control data.
