Abstract
The disclosure provides an approach for tracking metadata (e.g., accessed and dirty bits) of page tables at finer granularity than the size of the page tables. A disclosed herein, modification to existing hardware design may enable finer page table granularity of metadata, leading to more precise representation of the state of memory and an improvement to system performance and efficiency. Finer grain dirty metadata can dramatically improve the efficiency and simplicity of subsystems.
