# This script shows example usage of damo for access-aware weighted
# interleaving. The script assumes the system has two NUMA nodes of id 0 and 1.
# The script asks DAMON to interleave hot pages of the target process, passed
# as the first command line argument of this script, at a 1:1 ratio between
# nodes 0 and 1.
#
# To run this, the kernel should have the weighted interleaving support of
# DAMON[1], which is expected to land into mainline in v6.17-rc1.
