Abstract: Systems and methods for cache utilization are disclosed. In one embodiment, a graphics processor includes processing resources to perform graphics operations and a cache controller of a cache memory that is coupled to the processing resources. The cache controller is configured to set an initial aging policy using an aging field based on age of cache lines within the cache memory and to determine whether a hint or an instruction to indicate a level of aging has been received. In one embodiment, the cache memory configured to be partitioned into multiple cache regions, wherein the multiple cache regions include a first cache region having a cache eviction policy with a configurable level of data persistence.

Abstract: Apparatuses including general-purpose graphics processing units and graphics multiprocessors that exploit queues or transitional buffers for improved low-latency high-bandwidth on-die data retrieval are disclosed. In one embodiment, a graphics multiprocessor includes at least one compute engine to provide a request, a queue or transitional buffer, and logic coupled to the queue or transitional buffer. The logic is configured to cause a request to be transferred to a queue or transitional buffer for temporary storage without processing the request and to determine whether the queue or transitional buffer has a predetermined amount of storage capacity.

Abstract: Described herein is a technique to enhance the responsiveness of gameplay for a 3D gaming application while maintaining the ability to enqueue multiple frames for processing on the GPU. Each frame or a set of workloads within a frame is submitted to the GPU with predication, such that the indicated rendering and resource manipulation commands are not actually performed if the predication condition is enabled. A low latency command can be submitted to the GPU via a copy engine command queue. The command will cause the copy engine to enable or disable predication for command buffers in the command queue. When predication for queued command buffers is enabled, command buffers for workloads that are not related to the workload that is generated in response to the user input are bypassed. High priority command buffers that include workloads generated in response to user input can then be executed immediately.
