it might enter into kernel space to wake up those kthreads if
necessary).
+* **Added virtio Rx interrupt suppprt.**
+
+ This feature enables Rx interrupt mode for virtio pci net devices as
+ binded to VFIO (noiommu mode) and drived by virtio PMD.
+
+ With this feature, virtio PMD can switch between polling mode and
+ interrupt mode, to achieve best performance, and at the same time save
+ power. It can work on both legacy and modern virtio devices. At this mode,
+ each rxq is mapped with an exluded MSIx interrupt.
+
+ See the :ref:`Virtio Interrupt Mode <virtio_interrupt_mode>` documentation
+ for more information.
