Abstract: Described herein is a partitionable graphics processor having a plurality of flexibly partitioned processing resources. One embodiment provides a graphics processor comprising a plurality of processing resources configurable to be flexibly partitioned into a plurality of resource partitions and circuitry to compose multiple graphics processor device partitions from the plurality of resource partitions. The multiple graphics processor device partitions are configurable to be asymmetrically composed of different types of functional units.

Abstract: Described herein is a partitional graphics processor having multiple hard partitions with separate software execution and fault domains. One embodiment provides a graphics processor comprising a system interface and a plurality of graphics processing resources coupled with the system interface. The plurality of graphics processing resources is configurable to be partitioned into a plurality of isolated device partitions, each isolated device partition configured for fault isolation and independent concurrent execution of workloads associated with a plurality of clients, and the system interface is configured to present each of the plurality of isolated device partitions as a virtual function.

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 an apparatus comprising a processor to allocate a first memory space for data for a graphics workload, the first memory comprising a first plurality of addressable memory locations, allocate a second memory space for compression metadata relating to the data for the graphics workload, the second memory space comprising a second plurality of addressable memory locations and having an amount of memory corresponding to a predetermined ratio of the amount of memory allocated to first memory space, and configure a direct memory mapping between the first plurality of addressable memory locations and the second plurality of addressable memory locations. Other embodiments may be described and claimed.

Abstract: A virtual-to-virtual page table maps a main surface containing the actual data and a metadata or auxiliary surface that gives information about compression of the main surface. In order to access the metadata that corresponds to main surface, an additional virtual-to-virtual table may be used ahead of the regular page table mapping to avoid the need to pass the metadata base address and x, y coordinates across a pipeline which may result in multiple memory writes.
