Abstract: Security and support for trust domain operation is described. An example of a method includes processing, at an accelerator, one or more compute workloads received from a host system; upon receiving a notification that a trust domain has transitioned to a secure state, transition an original set of privileges for the accelerator to a downgraded set of privileges; upon receiving a command from the host system for the trust domain, processing the command in accordance with the trust domain; and upon receiving a request from the host system to access a register, for a register included in an allowed list of registers for access, allow access to the register, and, for a register that is not within the allowed list of registers for access, disallowing access to the register.

Abstract: Systems, apparatuses and methods may provide for encryption based technology. Data may be encrypted locally with a graphics processor with encryption engines. The graphics processor components may be verified with a root-of-trust and based on collection of claims. The graphics processor may further be able to modify encrypted data from a non-pageable format to a pageable format. The graphics processor may further process data associated with a virtual machine based on a key that is known by the virtual machine and the graphics processor.

Abstract: Embodiments described herein provide a graphics, media, and compute device having a tiled architecture composed of a number of tiles of smaller graphics devices. The work distribution infrastructure for such device enables the distribution of workloads across multiple tiles of the device. Work items can be submitted to any one or more of the multiple tiles, with workloads able to span multiple tiles. Additionally, upon completion of a work item, graphics, media, and/or compute engines within the device can readily acquire new work items for execution with minimal latency.
