 IOAT Rawdev Driver
 ===================
 
+.. warning::
+        As of DPDK 21.11 the rawdev implementation of the IOAT driver has been deprecated.
+        Please use the dmadev library instead.

 The ``ioat`` rawdev driver provides a poll-mode driver (PMD) for Intel\ |reg|
 Data Streaming Accelerator `(Intel DSA)
 <https://01.org/blogs/2019/introducing-intel-data-streaming-accelerator>`_ and for Intel\ |reg|

 For builds using ``meson`` and ``ninja``, the driver will be built when the target platform is x86-based.
 No additional compilation steps are necessary.
 
+.. note::
+        Since the addition of the dmadev library, the ``ioat`` and ``idxd`` parts of this driver
+        will only be built if their ``dmadev`` counterparts are not built.
+        The following can be used to disable the ``dmadev`` drivers,
