*Gather Demand Paging Execution Timing Histogram*

Type: ``bool``

Help
====

.. code-block:: none

    This gathers the histogram of execution time on page eviction
    selection, and backing store page in and page out.

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

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

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

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

Defaults
========

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