There are use cases that need to apply DAMOS schemes to specific address
ranges or DAMON monitoring targets. NUMA nodes in the physical address
space, special memory objects in the virtual address space, and
monitoring target specific efficient monitoring results snapshot
retrieval could be examples of such use cases. This patchset extends
DAMOS filters feature for such cases, by implementing two more filter
types, namely address ranges and DAMON monitoring types.
Patches sequence
----------------
The first seven patches are for the address ranges based DAMOS filter.
The first patch implements the filter feature and expose it via DAMON
kernel API. The second patch further expose the feature to users via
DAMON sysfs interface. The third and fourth patches implement unit
tests and selftests for the feature. Three patches (fifth to seventh)
updating the documents follow.
The following six patches are for the DAMON monitoring target based
DAMOS filter. The eighth patch implements the feature in the core layer
and expose it via DAMON's kernel API. The ninth patch further expose it
to users via DAMON sysfs interface. Tenth patch add a selftest, and two
patches (eleventh and twelfth) update documents.
