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

*Size of the exception stack(s)*

Type: ``int``

Help
====

.. code-block:: none

    The exception stack(s) (one per CPU) are used both for exception
    processing and early kernel/CPU initialization. They need only
    support limited call-tree depth and must fit into the low core,
    so they are typically smaller than the ISR stacks.

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

\ :kconfig:`X86_64 <CONFIG_X86_64>` && \ :kconfig:`X86 <CONFIG_X86>`

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