.. title:: HW_STACK_PROTECTION

.. option:: CONFIG_HW_STACK_PROTECTION

*Hardware Stack Protection*

Type: ``bool``

Help
====

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.
