CONFIG_HW_STACK_PROTECTION
##########################

*Hardware Stack Protection*

Type: ``bool``

Help
====

.. code-block:: none

    Select this option to enable hardware-based platform features to
    catch stack overflows when the system is running in privileged
    mode. If CONFIG_USERSPACE is not enabled, the system is always
    running in privileged mode.

    Note that this does not necessarily prevent corruption and assertions
    about the overall system state when a fault is triggered cannot be
    made.
