CONFIG_DEMAND_PAGING_STATS
##########################

*Gather Demand Paging Statistics*

Type: ``bool``

Help
====

.. code-block:: none

    This enables gathering various statistics related to demand paging,
    e.g. number of pagefaults. This is useful for tuning eviction
    algorithms and optimizing backing store.

    Should say N in production system as this is not without cost.

Direct dependencies
===================

\ :kconfig:`DEMAND_PAGING <CONFIG_DEMAND_PAGING>` && \ :kconfig:`MMU <CONFIG_MMU>`

*(Includes any dependencies from ifs and menus.)*

Defaults
========

No defaults. Implicitly defaults to ``n``.

Kconfig definition
==================



At ``<Zephyr Architecture>/Kconfig:715``

Included via ``Kconfig:8`` → ``Kconfig.zephyr:39``

Menu path: (Top) → Enable MMU features → Enable demand paging [EXPERIMENTAL]
