Hardware-assisted paging mechanisms

A method of computer memory management, the method comprising:

• accessing, through processing circuitry, a memory region of a memory device, the memory region subject to a memory reduction technique;
• obtaining an indication of memory reduction of the memory region;
• based on the indication of memory reduction, calculating metrics of cache lines associated with the memory region;
• and
• providing the metrics to a system software component for use in memory management mechanisms,
• wherein the memory reduction technique includes memory deduplication,
• wherein the indication of memory reduction is a reference count, the reference count enumerating a number of logical addresses that point to a physical address of a cache line of the cache lines associated with the memory region, and
• wherein calculating metrics of the cache lines associated with the memory region includes calculating a number of cache lines with a reference count value of one.

At least one non-transitory machine-readable medium including instructions for computer memory management, the instructions when executed by processing circuitry, cause the processing circuitry to perform the operations comprising:

• accessing a memory region of a memory device, the memory region subject to a memory reduction technique;
• obtaining an indication of memory reduction of the memory region;
• based on the indication of memory reduction, calculating metrics of cache lines associated with the memory region;
• and
• providing the metrics to a system software component for use in memory management mechanisms,
• wherein the memory reduction technique includes memory deduplication,
• wherein the indication of memory reduction is a reference count, the reference count enumerating a number of logical addresses that point to a physical address of a cache line of the cache lines associated with the memory region, and
• wherein calculating metrics of the cache lines associated with the memory region includes calculating a number of cache lines with a reference count value of one.
