For the system operations, DAMON providesa feature called DAMOS (Data Access Monitoring-based Operation Schemes). There is no sample API usage of DAMOS, though. Copy the working set sizeestimation sample modules with changed names of the module and symbols, touse it as a skeleton for a sample module showing the DAMOS API usage. Thefollowing commit will make it proactively reclaim cold memory of the givenprocess, using DAMOS.Link: https://lkml.kernel.org/r/20241210215030.85675-5-sj@kernel.orgSigned-off-by: SeongJae Park <sj@kernel.org>Signed-off-by: Andrew Morton <akpm@linux-foundation.org> List of files: /linux-6.15/samples/damon/Makefile Tue, 10 Dec 2024 21:50:29 +0000 SeongJae Park <sj@kernel.org> http://172.16.0.5:8080/history/linux-6.15/samples/damon/Makefile#19d7c3ad samples: add a skeleton of a sample DAMON module for working set size estimationPatch series "mm/damon: add sample modules".Implement a proactive cold memory regions reclaiming logic of prcl samplemodule using DAMOS. The logic treats memory regions that not accessed atall for five or more seconds as cold, and reclaim those as soon as found.This patch (of 5):Add a skeleton for a sample DAMON static module that can be used forestimating working set size of a given process. Note that it is a staticmodule since DAMON is not exporting symbols to loadable modules for now. It exposes two module parameters, namely 'pid' and 'enable'. 'pid' willspecify the process that the module will estimate the working set size of.'enable' will receive whether to start or stop the estimation. Becausethis is just a skeleton, the parameters do nothing, though. Thefunctionalities will be implemented by following commits.Link: https://lkml.kernel.org/r/20241210215030.85675-1-sj@kernel.orgLink: https://lkml.kernel.org/r/20241210215030.85675-2-sj@kernel.orgSigned-off-by: SeongJae Park <sj@kernel.org>Signed-off-by: Andrew Morton <akpm@linux-foundation.org> List of files: /linux-6.15/samples/damon/Makefile Tue, 10 Dec 2024 21:50:26 +0000 SeongJae Park <sj@kernel.org>
