*Intel VT-D interrupt remapping controller*

Type: ``bool``

Help
====

.. code-block:: none

    Such interrupt remapping hardware is provided through Intel VT-D
    technology. It's being used, currently, only for MSI/MSI-X
    multi-vector support. If you have such PCIe device requiring
    multi-vector support, you will need to enable this.

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

\ :option:`ACPI <CONFIG_ACPI>` && \ :option:`X86 <CONFIG_X86>` && \ :option:`64BIT <CONFIG_64BIT>`

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

Defaults
========

No defaults. Implicitly defaults to ``n``.
