Apparatuses, systems, and methods for controlling cache allocations in a configurable combined private and shared cache in a processor-based system

A processor-based system, comprising:

• means for receiving a cache allocation request including a client identifier (ID);
• means for comparing the cache allocation request and the client ID to a sub-Non-Uniform Memory Access (NUMA) bit mask and a client allocation bit mask to generate a cache allocation vector;
• means for selecting a processing core to receive the cache allocation request based on the cache allocation vector and a per-processing core weighting;
• and
• means for providing the cache allocation request to the processing core at an associated shared cache.

A method of controlling cache allocations in a configurable combined private and shared cache, comprising:

• receiving, by a vector generation circuit of a processor-based system, a cache allocation request;
• generating, by the vector generation circuit, an associated cache allocation vector based on a sub-Non-Uniform Memory Access (NUMA) bit mask and a client allocation bit mask;
• providing, by the vector generation circuit, the cache allocation vector to a cache selection circuit of the processor-based system;
• receiving, by the cache selection circuit, the cache allocation vector;
• and
• selecting, by the cache selection circuit, a processing core to receive the cache allocation request based on cache weighting information and the cache allocation vector.

A non-transitory computer-readable medium having stored thereon computer-executable instructions which, when executed by a processor, cause the processor to:

• receive a cache allocation request;
• generate an associated cache allocation vector based on a sub-Non-Uniform Memory Access (NUMA) bit mask and a client allocation bit mask;
• provide, by a vector generator, the cache allocation vector to a cache selection circuit of the processor;
• receive, by a cache selector, the cache allocation vector;
• and
• select a processing core to receive the cache allocation request based on cache weighting information and the cache allocation vector.
