77 mapping is not strictly required but could even incur a high overhead in some
109 bit(s) set again after one sampling period.  This could disturb other kernel

210 The monitoring target address range could dynamically changed.  For example,
211 virtual memory could be dynamically mapped and unmapped.  Physical memory could
214 As the changes could be quite frequent in some cases, DAMON allows the
240 operation changes for the regions.  The changes could be made by modifying or
242 reconfiguring the hardware.  Both offline and online approaches could be
