.. title:: RING_BUFFER

.. option:: CONFIG_RING_BUFFER

*Enable ring buffers*

Type: ``bool``

Help
====

Enable usage of ring buffers. This is similar to kernel FIFOs but ring
buffers manage their own buffer memory and can store arbitrary data.
For optimal performance, use buffer sizes that are a power of 2.

Defaults
========

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