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

*Enable MSI multi-vector support*

Type: ``bool``

Help
====

.. code-block:: none

    MSI can support up to 32 different messages. This will enable the
    support of such capability so each message can get a vector
    assigned to it. This will require for the selected architecture
    to provide the necessary logic to make it work. Disable this if
    the vectors cannot be managed by the hardware or if none of the
    peripheral require this.
