+config DAMON
+	bool "DAMON: Data Access Monitoring Framework"
+	help
+	  This builds a framework that allows kernel subsystems to monitor
+	  access frequency of each memory region. The information can be useful
+	  for performance-centric DRAM level memory management.
+
+	  See https://damonitor.github.io/doc/html/latest-damon/index.html for
+	  more information.

+	default KUNIT_ALL_TESTS
+	help
+	  This builds the DAMON Kunit test suite.
+
+	  For more information on KUnit and unit tests in general, please refer
+	  to the KUnit documentation.
+
+	  If unsure, say N.
+
+config DAMON_VADDR
+	bool "Data access monitoring primitives for virtual address spaces"
+	depends on DAMON && MMU
+	select PAGE_IDLE_FLAG
+	help
