The core -monitoring :ref:`mechanisms <damon_design_monitoring>` of DAMON make it - - - *accurate* (the monitoring output is useful enough for DRAM level memory - management; It might not appropriate for CPU Cache levels, though), - - *light-weight* (the monitoring overhead is low enough to be applied online), - and - - *scalable* (the upper-bound of the overhead is in constant range regardless - of the size of target workloads). - -Using this framework, therefore, the kernel can operate system in an -access-aware fashion. Because the features are also exposed to the :doc:`user -space </admin-guide/mm/damon/index>`, users who have special information about -their workloads can write personalized applications for better understanding -and optimizations of their workloads and systems. - -For easier development of such systems, DAMON provides a feature called -:ref:`DAMOS <damon_design_damos>` (DAMon-based Operation Schemes) in addition -to the monitoring. Using the feature, DAMON users in both kernel and :doc:`user -spaces </admin-guide/mm/damon/index>` can do access-aware system operations -with no code but simple configurations. +DAMON is a Linux kernel subsystem for efficient :ref:`data access monitoring +<damon_design_monitoring>` and :ref:`access-aware system operations +<damon_design_damos>`.
