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_KUNIT_TEST
bool "Test for damon" if !KUNIT_ALL_TESTS
depends on DAMON && KUNIT=y
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
This builds the default data access monitoring primitives for DAMON
that work for virtual address spaces.
config DAMON_PADDR
bool "Data access monitoring primitives for the physical address space"
depends on DAMON && MMU
select PAGE_IDLE_FLAG
help
This builds the default data access monitoring primitives for DAMON
that works for the physical address space.
config DAMON_VADDR_KUNIT_TEST
bool "Test for DAMON primitives" if !KUNIT_ALL_TESTS
depends on DAMON_VADDR && KUNIT=y
default KUNIT_ALL_TESTS
help
This builds the DAMON virtual addresses primitives 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_DBGFS
bool "DAMON debugfs interface"
depends on DAMON_VADDR && DAMON_PADDR && 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.
config DAMON_DBGFS_KUNIT_TEST
bool "Test for damon debugfs interface" if !KUNIT_ALL_TESTS
depends on DAMON_DBGFS && KUNIT=y
default KUNIT_ALL_TESTS
help
This builds the DAMON debugfs interface Kunit test suite.
