*Enable support for dynamic direct interrupts*

Type: ``bool``

Help
====

.. code-block:: none

    Direct interrupts are designed for performance-critical interrupt
    handling and do not go through all of the common interrupt handling
    code. This option enables the installation of interrupt service
    routines for direct interrupts at runtime.
    Note: this requires enabling support for dynamic interrupts in the
    kernel.
