.. title:: DYNAMIC_DIRECT_INTERRUPTS

.. option:: CONFIG_DYNAMIC_DIRECT_INTERRUPTS

*Enable support for dynamic direct interrupts*

Type: ``bool``

Help
====

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.
