Drivers that support CEC will create a CEC device node (/dev/cecX) to
give userspace access to the CEC adapter. The
:ref:`CEC_ADAP_G_CAPS` ioctl will tell userspace what it is allowed to do.

+In order to check the support and test it, it is suggested to download
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ package. It
+provides three tools to handle CEC:
+
+- cec-ctl: the Swiss army knife of CEC. Allows you to configure, transmit
+ and monitor CEC messages.
+
+- cec-compliance: does a CEC compliance test of a remote CEC device to
+ determine how compliant the CEC implementation is.

+- cec-follower: emulates a CEC follower.

Description
===========
-.. note::
-
- This documents the proposed CEC API. This API is not yet finalized
- and is currently only available as a staging kernel module.
-
To receive a CEC message the application has to fill in the
``timeout`` field of struct :c:type:`cec_msg` and pass it to
:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
