The address space11specific monitoring operations including monitoring target regions12constructions and actual access checks can be implemented and configured on the13DAMON core by the users. In this way, DAMON users can monitor any address14space with any access check technique.15 16Nonetheless, DAMON provides vma/rmap tracking and PTE Accessed bit check based17implementations of the address space dependent functions for the virtual memory18and the physical memory by default, for a reference and convenient use.19 20 21Can I simply monitor page granularity?22======================================23 24Yes.
