| |
DAMON sysfs interface exposes access rate of each region via DAMOS tried regions directory. For this, the nr_accesses field of the region is used. DAMOS was actually using nr_accesses in the past, but it uses nr_accesses_bp now. Use the value that it is really using as the source.
Note that this doesn't expose nr_accesses_bp as is (in basis point), but after converting it to the natural number by dividing the value by 10,000. Hence there is no behavioral change from users' perspective.
