*(No prompt -- not directly user assignable.)*

Type: ``bool``

Help
====

.. code-block:: none

    This hidden option enables defining a Task State Segment (TSS) for
    kernel execution. This is needed to handle double-faults or
    do privilege elevation. It also defines a special TSS and handler
    for correctly handling double-fault exceptions, instead of just
    letting the system triple-fault and reset.
