But CEC should be independent in functionality with audio/video though it is A/V related. I prefer to support only CEC frame TX/RX in kernel. CEC include different category features that need parsing and may need application interaction. Venders may also configure some features as not supported. If kernel support more than TX/RX, policy may be separated to user space part and kernel space part. The kernel interface also becomes complex, maybe ambiguous too. An user space library is more suitable for this task to interact with OS/media player/audio control/etc.
