Dynamically adjusting memory allocations based on quality-of-service (QoS) pool threshold values in processor-based devices

A method for dynamically adjusting memory allocations, comprising:

• for each pool of a plurality of pools, wherein memory accesses are categorized into a plurality of access categories, and wherein each pool of the plurality of pools is a logical portion of a dedicated storage device and corresponds to one or more access categories of the plurality of access categories:
• determining usage of the pool;
• evaluating whether the usage of the pool exceeds a threshold, wherein a corresponding allocation constraint of a plurality of allocations constraints is set for stored memory access of the one or more access categories of the corresponding pool;
• and
• responsive to the usage of the pool exceeding the threshold, modifying the allocation constraint, wherein modifying the allocation constraint maintains request throughput of the memory accesses over variations in the usage of the pools.

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

• for each pool of a plurality of pools, wherein memory accesses are categorized into a plurality of access categories, and wherein each pool of the plurality of pools is a logical portion of a dedicated storage device and corresponds to one or more access categories of the plurality of access categories:
• determine usage of the pool;
• evaluate whether the usage of the pool exceeds a threshold, wherein a corresponding allocation constraint of a plurality of allocations constraints is set for stored memory access of the one or more access categories of the corresponding pool;
• and
• responsive to the usage of the pool exceeding the threshold, modifying the allocation constraint, wherein modifying the allocation constraint maintains request throughput of the memory accesses over variations in the usage of the pools.
