Hard partitioning via intra-SOC composition

A method comprising:

• configuring a number of cache and memory partitions for a graphics processing unit of a multi-client server device, wherein the graphics processing unit is partitionable into a plurality of isolated device partitions, each of the plurality of isolated device partitions having an independent reset and power management domain configured for fault isolation and independent workload execution;
• configuring a number of compute partitions for the graphics processing unit;
• compositing isolated device partitions of the graphics processing unit via selection, from collections of fixed function and programmable logic within the graphics processing unit, of one or more cache partitions, memory partitions, fixed function units, and compute partitions for each device partition;
• partitioning memory bandwidth among the isolated device partitions;
• configuring capabilities for the isolated device partitions, wherein configuring the capabilities for the isolated device partitions includes configuring render and media processing capabilities for the isolated device partitions based on selected fixed function units;
• and
• executing multiple workloads in parallel from multiple clients of the multi-client server device via multiple isolated device partitions of the graphics processing unit, the multiple workloads executed according to configured capabilities of the isolated device partitions.
