The end physical address of memory region that DAMON_LRU_SORT will do work against. By default, biggest System RAM is used as the region. +addr_unit +--------- + +A scale factor for memory addresses and bytes. + +This parameter is for setting and getting the :ref:`address unit +<damon_design_addr_unit>` parameter of the DAMON instance for DAMON_RECLAIM. + +``monitor_region_start`` and ``monitor_region_end`` should be provided in this +unit. For example, let's suppose ``addr_unit``, ``monitor_region_start`` and +``monitor_region_end`` are set as ``1024``, ``0`` and ``10``, respectively. +Then DAMON_LRU_SORT will work for 10 KiB length of physical address range that +starts from address zero (``[0 * 1024, 10 * 1024)`` in bytes). + +Stat parameters having ``bytes_`` prefix are also in this unit. For example, +let's suppose values of ``addr_unit``, ``bytes_lru_sort_tried_hot_regions`` and +``bytes_lru_sorted_hot_regions`` are ``1024``, ``42``, and ``32``, +respectively. Then it means DAMON_LRU_SORT tried to LRU-sort 42 KiB of hot +memory and successfully LRU-sorted 32 KiB of the memory in total. + +If unsure, use only the default value (``1``) and forget about this. + kdamond_pid ----------- |
