HDMI CEC: What? Why? How? - Hans Verkuil, Cisco Systems Norway

The HDMI connector features a CEC (Consumer Electronics Control) pin that allows connected devices to detect and control one another. This talk describes what CEC is, why you would want to implement support for it, and how you can use the new kernel framework and API that was introduced in kernel 4.8 to support this HDMI feature. In addition to describing the framework, this presentation will also demonstrate CEC compliance tests that were created to test both your own CEC application code and the CEC implementation of other CEC devices.
