SPDX-License-Identifier: GPL-2.0 2 3========================== 4Frequently Asked Questions 5========================== 6 7Does DAMON support virtual memory only? 8======================================= 9 10No. The core of the DAMON is address space independent. The address space 11specific monitoring operations including monitoring target regions 12constructions and actual access checks can be implemented and configured on the 13DAMON core by the users. In this way, DAMON users can monitor any address 14space with any access check technique. 15 16Nonetheless, DAMON provides vma/rmap tracking and PTE Accessed bit check based 17implementations of the address space dependent functions for the virtual memory 18and the physical memory by default, for a reference and convenient use. 19 20 21Can I simply monitor page granularity? 22====================================== 23 24Yes. You can do so by setting the ``min_nr_regions`` attribute higher than the 25working set size divided by the page size. Because the monitoring target 26regions size is forced to be ``>=page size``, the region split will make no 27effect. 28
