#####################

*Enable separate firq stack*

Type: ``bool``

Help
====

.. code-block:: none

    Use separate stack for FIRQ handing. When the fast irq is also a direct
    irq, this will get the minimal interrupt latency.

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

\ :kconfig:`ARC_FIRQ <CONFIG_ARC_FIRQ>` && \ :kconfig:`RGF_NUM_BANKS <CONFIG_RGF_NUM_BANKS>` > 1 && \ :kconfig:`ARC <CONFIG_ARC>`

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

Defaults
========

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