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.
config DAMON_VADDR
bool "Data access monitoring primitives for virtual address spaces"
depends on DAMON && MMU
select PAGE_IDLE_FLAG
help
This builds the default data access monitoring primitives for DAMON
that works for virtual address spaces.
config DAMON_DBGFS
bool "DAMON debugfs interface"
depends on DAMON_VADDR && DEBUG_FS
help
This builds the debugfs interface for DAMON. The user space admins
can use the interface for arbitrary data access monitoring.
If unsure, say N.
