@ -358,3 +358,15 @@ example, the memory cgroup filter type asks users to specify the file path of
the memory cgroup for the filter. Hence, users can apply specific schemes to
only anonymous pages, non-anonymous pages, pages of specific cgroups, all pages
excluding those of specific cgroups, and any combination of those.
Application Programming Interface
---------------------------------
The programming interface for kernel space data access-aware applications.
DAMON is a framework, so it does nothing by itself. Instead, it only helps
other kernel components such as subsystems and modules building their data
access-aware applications using DAMON's core features. For this, DAMON exposes
its all features to other kernel components via its application programming
interface, namely ``include/linux/damon.h``. Please refer to the API
:doc:`document </mm/damon/api>` for details of the interface.
