.. title:: PCIE_MSI_MULTI_VECTOR

.. option:: CONFIG_PCIE_MSI_MULTI_VECTOR

*Enable MSI multi-vector support*

Type: ``bool``

Help
====

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.

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

\ :option:`PCIE_MSI <CONFIG_PCIE_MSI>` && \ :option:`PCIE <CONFIG_PCIE>`

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

Defaults
========

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