| Frequently Asked Questions |
| ========================== |
| |
| Does DAMON support virtual memory only? |
| ======================================= |
| |
| No. The core of the DAMON is address space independent. The address space |
| specific monitoring operations including monitoring target regions |
| constructions and actual access checks can be implemented and configured on the |
| DAMON core by the users. In this way, DAMON users can monitor any address |
| space with any access check technique. |
| |
| Nonetheless, DAMON provides vma/rmap tracking and PTE Accessed bit check based |
| implementations of the address space dependent functions for the virtual memory |
| and the physical memory by default, for a reference and convenient use. |
| |
| |
| Can I simply monitor page granularity? |
| ====================================== |
| |
| Yes. You can do so by setting the ``min_nr_regions`` attribute higher than the |
| working set size divided by the page size. Because the monitoring target |
| regions size is forced to be ``>=page size``, the region split will make no |
| effect. |
